Description

 Membrane method Coloring method of stucco composition

 The present invention relates to a method for uniformly and stably coloring a colored stucco composition while suppressing color separation. In particular, the present invention relates to a method for suppressing color separation and uniformly and stably coloring a colored stucco composition containing water, in other words, a method for maintaining coloring stability.

 Further, the present invention provides a method for coloring a stucco composition useful for suppressing color unevenness of a colored stucco coating film and the occurrence of color difference due to overcoating, and a stucco composition useful for suppressing color skipping of a colored stucco coating film. It relates to a method of coloring an object.

 Furthermore, the present invention relates to a method for suppressing the occurrence of color difference in colored stucco by repeated coating of a colored stucco composition, and a method for suppressing color jump of a colored stucco coating film.

 Background art

 Plaster has a calm and dignified finish, and also has excellent functions such as humidity control (moisture absorption and moisture release), mold resistance and fire protection. This is a building material used as a painted wall material.

 Conventionally, plastering is generally performed by first kneading lime and a binder, which are raw materials, with water and preparing the materials on site. However, since the proportions of lime, binder and water vary depending on the experience and skills of each plasterer, there is a problem that there is a tendency for differences between the vendors and constant quality cannot be obtained. For this reason, a form in which only lime and a binder are mixed in advance and only water is blended on site (powder mixed stucco composition), or a form in which lime, a binder and water are preliminarily mixed and used immediately on site (Pre-prepared stucco composition, water-containing stucco composition) are required.

 In addition, plaster basically has a white color based on the color of the main material, lime (white plaster), but in recent years there has been a demand for colored plaster colored in various colors in accordance with the diversification of customer needs. It can be done. However, it has been pointed out that colorants are generally difficult to disperse evenly in lime, so they tend to separate when mixed with lime, which causes color unevenness in the colored stucco coating film. (For example, see JP-A-7-19663

No. 55, and Japanese Patent Application Laid-Open No. 91-56698).

 Disclosure of invention

 An object of the present invention is to solve the problem of the conventional on-site preparation (preparation at the time of use) of plaster and the problem of coloring of plaster. Specifically, the present invention is a colored stucco coating material prepared by adding a binder and a coloring agent, or further adding water to lime in advance so that it can be used easily or immediately without the need for on-site preparation and toning. The purpose is to provide a method for stably supplying water. More specifically, the present invention provides a method for coloring a stucco composition, in particular, a stucco composition capable of significantly suppressing color unevenness and color skipping when a coating film is formed, or generation of a color difference when overcoated. An object of the present invention is to provide a method for coloring an object. The present invention also provides a method for coloring a water-containing stucco composition, in particular, a method for coloring a water-containing stucco composition capable of suppressing color separation during storage, and a method for stably maintaining the coloring of the water-containing stucco composition. The purpose of the present invention is to provide a form.

 Still another object of the present invention is to provide a method for suppressing the occurrence of a color difference due to overcoating of a colored stucco composition, and a method for suppressing color jump of a colored stucco coating film. To supply color stucco materials to the market in a state where lime is pre-mixed with a binder and a coloring agent or water so that it can be used easily without the need for on-site blending and toning, the main material is lime. It is necessary to color the stucco composition uniformly, and to maintain the coloring stably. Such uneven coloring and color separation of the composition is one of the causes of color unevenness and color difference of the coating film to be formed, and significantly impairs the commercial value as a decorative coating material (finish coating material).

According to the coloring method, it was confirmed that even when a coating film was formed, color skipping and color unevenness were significantly suppressed, and that a colored stucco coating film having almost no color difference could be formed even when coating was performed repeatedly. Further, the present inventors have found that the water-containing colored stucco composition colored by the above-described method maintains a stable colored state in which color separation is suppressed in a state of being filled in a water-resistant container and packed. In this way, it can be supplied stably to the market and long-term storage is possible. And confirmed. The present invention has been developed based on these findings.

Specific examples of those having such an action include potassium sulfate, alum, fine powder of dihydrated water, and organic acids such as oxalic acid.

 (1-36) The colored stucco composition thus prepared is color-separated by mixing a white pigment with lime and coloring the base with the colored pigment as shown in an experimental example described later. And is uniformly and stably colored throughout the composition. The determination of whether or not the colored stucco composition is uniformly colored (uniformly colored) throughout the composition without discoloration is determined by a colored stucco composition (water-containing stucco composition) prepared by blending water. ) In a transparent container (or transparent bag) with stirring or after standing, it can be visually judged. The determination can also be made by applying (painting) the prepared water-containing colored stucco composition to a substrate and observing the formed ^ E for color unevenness.

(1-37) The water-containing colored stucco composition, which is uniformly and stably colored by the method of the present invention, has color unevenness as shown in Experimental Examples 1 and 3, etc. It can be used effectively to form a colored stucco coating film in which the occurrence of a color difference from the overcoated surface (difference in chromaticity, color, hue or color tone on the E surface) is suppressed. Therefore, the coloring method of the present invention is also a coloring method that simultaneously suppresses color unevenness of the colored plaster coating film after drying, and a coloring method that suppresses the color difference caused by repeatedly applying the water-containing colored plaster composition. In addition, as shown in Experimental Examples 2 and 3, coloring was performed by the method of the present invention. By using the water-containing colored stucco composition thus obtained, it is possible to significantly suppress whitening due to the color skipping characteristic of the colored stucco coating film. Therefore, the coloring method of the present invention is also a coloring method that simultaneously suppresses color skipping of the colored stucco coating film or whitening thereof. In addition, as shown in Experimental Example 3 etc., by suppressing the color jump of the colored stucco coating, the problem of color unevenness over time of the colored stucco coating and the color difference due to overcoating can be eliminated. From this, the phenomenon of color unevenness and the occurrence of color difference due to overcoating, which are remarkably observed in colored stucco ^ E, is due to the fact that lime, which is the main component of stucco, especially colored stucco, which is generated due to slaked lime being a strong alkali. This is considered to be caused by color skipping and white color dangling (a phenomenon in which white lime floats) due to color skipping.

 (1-38) The water-containing colored stucco composition colored by the method of the present invention is preferably colored unevenness or color difference due to overcoating (particularly, color unevenness due to whitening due to color skipping or color difference due to overcoating). Is reduced to such an extent that the value of the product as a decorative coating material (finish coating material) is not impaired. However, the use of white pigments together makes the color unevenness and overlap more than when white pigments are not used. The present invention belongs to the technical scope of the present invention as long as the effect of suppressing color difference generation due to coating, particularly the effect of suppressing color unevenness due to color skipping and color difference generation due to overcoating, is recognized.

 (2) Method for suppressing occurrence of color difference by repeatedly applying 7-containing colored stucco composition

 (2-1) As described in the above (1-37), the water-containing colored stucco composition colored by the method of the present invention described in (1) has a color difference in the colored stucco even when repeatedly applied. It can be effectively used to form a colored stucco coating film having a uniform color, in which the generation is significantly suppressed and the coating is inconspicuous. Therefore, the present invention provides, from another angle, a method for suppressing the occurrence of color difference in a colored stucco coating film caused by overcoating of a water-containing colored stucco composition containing lime as a main component.

 (2-2) This method can be achieved by employing the method described in detail in (1) as a method for coloring the stucco composition. Specifically, it can be carried out by coloring a stucco composition containing lime, a white pigment, a binder, and water using a coloring pigment. In other words, the present invention provides a water-containing colored stucco composition for forming a colored stucco coating film by using a composition prepared by mixing lime, a white pigment, a colored pigment, a binder and water. Can be implemented.

(2-3) The type and amount of lime and binder used for coloring the water-containing stucco composition (preparation of colored stucco composition), the type and amount of white pigment and color pigment, and the percentage of water The method described in the above (1) can be used in the same manner as the compounding and blending method (α-3) to (1-14) and the like). As for other components that can be incorporated into the water-containing colored stucco composition, the same components as described in the above (1) can be used ((1-15) to (1-35) (2-4) In addition, the method of applying the 7-containing colored stucco composition is not particularly limited, and the usual method used for coating the coating material and the paint [brush coating, roller coating, spray coating (airless gun, Air spray)] can be similarly used.

 (3) Method to control color unevenness of colored stucco

 (3-1) Lime is a highly alkaline component with a pH of about 9.5 to 12.6. For this reason, it is difficult for a stucco composition containing lime as a main component to evenly color even when an alkali-resistant coloring pigment is used, and the formed stucco coating film fades or fades over time due to drying. (See Experimental Examples 1-3). Then, it is considered that it causes color unevenness.

 (3-2) As described in (37) above, the method for coloring the stucco composition of the present invention described in (1) may be effectively used for suppressing such color unevenness of the colored stucco coating film. Can be. Therefore, the present invention provides a method for suppressing the occurrence of color unevenness in colored stucco containing lime as a main component from another angle.

 (3-3) This method can be achieved by employing the method described in detail in (1) as a method for coloring a water-containing stucco composition used for forming a colored stucco coating film. Specifically, it can be carried out by coloring a stucco composition containing lime, a white pigment, a binder, and water using a coloring pigment. In other words, the present invention can be practiced by forming a water-containing colored stucco composition which is colored by mixing and preparing lime, white pigment, coloring pigment, binder and water. Thus, colored stucco without color unevenness can be formed, and the occurrence of color unevenness can be significantly suppressed by suppressing non-uniform color fading caused by color skipping that occurs over time.

 (3-4) Here, the types and proportions of lime, white pigments, coloring pigments, and binders used in the preparation of the water-containing colored stucco composition used for formation, the proportion of water, the proportion of water, and the preparation method are as described above. It is as described in (1) (see (Part 3) to (Part 14), etc.). Further, as other components that can be blended in the water-containing colored stucco composition, the same components as described in the above (1) can be used (see (1-15) to (1-35)).

 (3-5) In addition, the method of applying the 7K-containing colored stucco composition is not particularly limited, and the usual method used for coating the coating material and the coating material [brush coating, one roller coating, spray coating (airless gun) , Air spray)] can be used as well.

(3-6) Although not being bound by theory, the effect of the colored stucco coating film of the present invention for suppressing color unevenness is determined by coloring based on a mixture of lime and a white pigment to contain water used for construction. Stucco composition can be uniformly and stably colored, and It can be inferred that this is due to the result that the release (color skipping) of the colored pigment, which can be caused by the drying of the colored stucco coating film formed with the lapse of time and the transpiration of water over time, is significantly suppressed.

 (3-7) The method of the present invention can be effectively used for forming a colored stucco coating film having uniform color with suppressed color unevenness.

 (4) Color plaster ¾ J3 color jump suppression method

 (4-1) As described above, lime is a highly alkaline component having a pH of about 9.5 to 12.6, so that a plaster composition containing lime as a main component is an alkali-resistant coloring pigment. Even when lacquer is used, uniform coloring is difficult, and the formed colored stucco coating is liable to cause color jump (whitening) with drying and over time (see Experimental Examples 2 and 3). Such color skip causes color unevenness during drying of the colored stucco coating film and over time. In addition, the coloring of the colored stucco coating and the whitening of the coating due to the color skipping (phenomenon of white lime floating on the colored stucco coating) are particularly remarkable when the water-containing colored stucco composition is overcoated. However, this may cause color difference when coating is applied repeatedly (Experimental example 3).

 (4-2) ± 13 As described in (1-37), the water-containing colored stucco composition colored by the method of the present invention described in (1) is useful for suppressing color jump of a colored stucco coating film. Can be used effectively. Therefore, the present invention provides a method for suppressing color jumping of a colored stucco coating film containing lime as a main component and suppressing whitening of a colored stucco coating film by the colored stucco coating film containing lime as a main component.

 (4-3) This method can be achieved by employing the method described in detail in (1) as a method for coloring the water-containing stucco composition. Specifically, it can be carried out by coloring a stucco composition containing lime, a white pigment, a binder, and water using a coloring pigment. In other words, the present invention can be practiced by forming a water-containing colored stucco composition which is prepared by mixing lime, white pigment, coloring pigment, binder and water. Thus, according to the present invention, even when the coating is performed while sequentially applying the coating, or when the coating is performed repeatedly such as the first coating and the second coating or the repair coating, it may occur between the undercoat surface and the overcoat surface. The color difference (particularly the color difference generated between the painted surface and the other surface) can be significantly suppressed.

 (4-4) Here, the types and blending ratios of lime, white pigments, coloring pigments, and binders used in the preparation of the water-containing colored stucco composition used in the formation, the proportions of water, and the preparation method are as described in the above ( It is as described in 1) (see (3) to α-14). In addition, the same components as described in the above (1) can be used for other components that can be blended with the water-containing colored stucco composition (see (1-15) to (1-35)).

(4-5) In addition, the method of applying the 7-containing colored stucco composition is not particularly limited, either. The usual methods used for coating (brush coating, roller coating, spray coating (airless gun, air spray)) can be used as well.

 (4-6) It is to be noted that, without being bound by theory, the effect of suppressing the occurrence of color difference due to the repeated application of the colored stucco coating film according to the present invention is to color with a color pigment based on a mixture of lime and white pigment. Thus, the water-containing stucco composition used for construction can be uniformly and stably colored, and the release of color pigments (color skipping) that may occur due to water evaporation during drying of the formed colored stucco coating film is significant. It can be inferred that this is due to the suppressed results.

The container having such a carbon dioxide barrier property may be one having a carbon dioxide permeation resistance to such an extent that the water-containing colored stucco composition contained in the container is not adversely affected (solidified). For example, in addition to ordinary paint containers, containers made of a film or sheet constituting a flexible container can be used by appropriately selecting the material and the thickness thereof.

 (5-2) In the latter case, as a carbon dioxide barrier material, polyvinylidene chloride resin (PVDC), various (poly) vinylidene chloride coat films, ethylene vinyl alcohol film, ethylene-vinyl acetate copolymer are generally used.

 (5-5) The water vapor barrier property may be any as long as the plaster composition contained in the container has a water vapor permeation resistance to such an extent that the plaster composition is not adversely affected (drying and solidification). For example, in addition to ordinary paint containers, containers made of a film or sheet constituting a flexible container can be used by appropriately selecting the material and the thickness thereof.

 (5-6) In the case of the latter, polyvinylidene chloride-based resin (PVDC), various (poly) vinylidene chloride coated films, moisture-proof cellophane (lacquer-coated cellophane, polymer-coated cellophane), polyester, PVDC coated polyester, PVDC coated nylon, polyvinyl chloride, polyethylene (low density, medium density, high density, especially high density polyethylene), linear lowden polyethylene, stretched polyethylene, unstretched polypropylene, stretched polypropylene, ethylene monoacetate Synthetic resins such as copolymers, ionomers, aluminum foil laminating films, and evaporated films of inorganic substances such as silicon oxide and aluminum oxide are known. In the present invention, a film having a water vapor barrier property can be suitably selected and used without any particular limitation. Generally, when the water-containing colored stucco composition targeted by the present invention is housed in a water-resistant container in an airtight state and stored at room temperature (20 ± 5) for at least one month, the internal stucco composition If drying and solidification are not observed in the container, it can be determined that the container has steam barrier properties.

Such a water vapor barrier property can be adjusted by adjusting the thickness of a known water vapor barrier material, or by forming a film into two or more layers or multiple layers so as to include a laminate layer made of the material. It can be achieved by preparing as a layer film.

 (5-8) Further, a container suitable as a container used in the present invention has water resistance, preferably has further flexibility, and more preferably has a carbon dioxide barrier property and a steam barrier property. . Such a container may be a single-layer film composed of one kind of resin, or a multi-layer or multilayer film having a laminated structure (laminated layer or coat layer) of two or more resin films. There may be. In addition, it does not matter whether the film is a non-stretched film or a stretched film (uniaxially stretched or biaxially stretched). Preferably, a film coated on at least one side with polyvinyl alcohol (PVA) resin (such as PVA-coated biaxially stretched polypropylene film), and a film coated on at least one side with polyvinylidene chloride (PVDC) resin (P VD C coated biaxially oriented polypropylene film, P VD C coated polyester film, PP / PVDC / PP, etc., Polyolefin unstretched coextruded multilayer film (PP / PE / PP, polyolefin (PE, PP, etc.)) Polyvinylidene chloride Z Examples are, but not limited to, these.

Is preferred. Multilayer or multilayer films may be used to satisfy these different properties. In this case, it is preferable that at least the inner layer of the container has resistance to heat and heat sealability.

 (5-10) Particularly from the liquid property of the water-containing colored stucco composition contained in the container, the container used in the present invention may have at least an inner surface in contact with the stucco composition having alkali resistance. preferable. For this purpose, a method using an alkali-resistant container, a method of coating the inner surface of a container such as a film can with an alkali-resistant resin, a method of using an alkali-resistant resin film on the inner surface of the film, and the like are used. it can. Examples of the alkali-resistant resin include vinyl chloride, vinyl acetate, and urethane resin. Preferably, homopolymers of vinyl polymers (for example, those having a weight average molecular weight of 20,000 or more) or copolymers and / or alkali-resistant urethane resins (for example, those having a weight average molecular weight of 100,000 or more) And polyvinyl chloride and a vinyl chloride-vinyl acetate copolymer. In the present invention, the term "alkali resistance" means that even when the stucco composition as a content is put at room temperature for 3 months, preferably 6 months, dissolution or corrosion of the container film is not visually observed. More preferably, it is desirable to use one that can obtain alkali resistance in the following accelerated test.

(5-11) <Accelerated test for evaluation of resistance to resistance> A 1N aqueous hydroxide solution is placed in a water-resistant container, allowed to stand in a thermostat at 50 ° C for 6 hours, then left at room temperature for 18 days, and then the potassium hydroxide aqueous solution is taken out. Then, visually inspect the inside of the container for dissolution or corrosion.

 (5-12) In the case of a film, the thickness to be adopted (the thickness of the container) is not particularly limited as long as it satisfies the above-mentioned carbon dioxide barrier properties and water vapor barrier properties, but is preferably 3 to 3 times. 0 m, more preferably 5 to 200 m. If the thickness is less than the above, the strength, impact resistance, pinhole resistance, and carbon dioxide barrier property are likely to be insufficient. ) And transparency tend to be insufficient. It is more preferably from 10 to 100 m, and still more preferably from 10 to 80 m.

 (5-13) Although transparency as a film is not particularly required, it is better for the colored stucco composition to be contained as contents to be less affected by light due to its excellent weather resistance, and for the contents to be recognizable from outside. Therefore, it is desirable to have transparency. In this case, transparency means that the contents can be seen visually.

As the easily tearable technique, any conventionally known technique can be used arbitrarily, for example, forming a V notch or a U notch, using a tear tape, using a needle-like filler, forming a perforation, or forming a fine surface on the film surface. Examples of the method include making a scratch. In addition, as long as the above properties are satisfied, an easy-opening material obtained by laminating a uniaxially stretched polyolefin film on the intermediate layer of the film (for example, a biaxially stretched polyester film, a nonaxially stretched polyolefin film, and a three-layer unstretched polyolefin film Laminated film) can also be used.

 (5-15) Further, the container used in the present invention may be provided with reclosing means such as a zipper at the opening.

(5-16) The method of filling the water-resistant container with the stucco composition is not particularly limited, but preferably, the filling is performed so that air is not mixed as much as possible at the time of filling, and then the filling port is heat-sealed. (Bar seal, hot-melt seal, hot-melt seal), impulse seal, high-frequency seal or ultrasonic seal, etc., and a method of hermetically sealing (sealing) can be used.

Can be kept. In particular, the water-containing colored stucco composition can be stably maintained in a state where non-uniformity of content components such as solidification, water separation, and color separation is significantly prevented. After the container has been opened, the contents harden or solidify over time due to contact with air, but this can be prevented by sealing to prevent air from re-entering. The water-containing colored stucco composition is preferably contained in a container in such a dosage that it can be used up once or two or three times. The content weight is not limited, but may be, for example, 0.5 to 5 kg. Figures 1 and 2 show examples of stucco packages prepared using flexible containers.

1: red iron oxide, 2: yellow iron oxide, 3: black iron oxide As a result, Comparative Composition 4 (without white pigment) using precipitated calcium carbonate in place of lime gradually darkens the color of the coated surface as the second and third coatings are applied. On the other hand, Comparative Composition 3 (without white pigment) using lime, on the other hand, gradually becomes white on the coated surface as the second coating and the third coating are repeated (the white color obtained by the repeated coating). ). The whitening phenomenon caused by the overcoating of the lime composition (comparative composition 3) is based on the fact that the lime is strongly alkaline, and is caused by color skipping caused by the evaporation of water. It was considered to be a problem specific to the plaster composition. It was considered that such color skipping and whitening due to the color skipping were the causes of the color difference due to the overcoating of the colored stucco composition and the color unevenness occurring over time. On the other hand, the colored stucco composition (the composition of the present invention) of the present invention in which lime is blended with a white pigment has significantly suppressed color skipping and whitening, and has a two-coat surface and a 3 Each of the first-coated surfaces had the same color tone (chromaticity, hue, and color) as the first-coated surface, and no color difference was visually observed. For this reason, by coloring lime using a white pigment and a coloring pigment, the color jump of the coloring pigment caused by the strong alkali of lime can be significantly suppressed, and as a result, the overlapping that is peculiar to the colored stucco composition It was found that it was possible to suppress the occurrence of color difference due to coating, the generation of colored plaster, and the occurrence of color unevenness. In this experiment, since the test plate which had been previously primed with a sealer containing titanium oxide was used, the coated surfaces of Comparative Compositions 3 and 4 were colored in the same manner as when the composition of the present invention was used. I was able to finish it evenly. Experiment 4

 According to the coloring method of the present invention, it is possible to uniformly color lime, which has conventionally been considered difficult, and it is possible to stably color the stucco composition while suppressing color separation over time. Non-uniform coloring of the stucco composition or color separation due to storage is one of the causes of uneven color of the formed stucco coating film. Therefore, the method for coloring a stucco composition of the present invention can be usefully used for forming a colored stucco having no color unevenness. Furthermore, according to the coloring method of the present invention, it is possible to significantly suppress the color jump of the colored stucco coating film, which is considered to be caused by the high strength of lime, and the whitening due to it. The color jump phenomenon of the colored stucco coating film is remarkably recognized by the water transpiration during drying of the colored stucco coating film and the water transpiration over time due to the moisture absorption and desorption properties of the stucco. Therefore, it is considered that the occurrence of color difference and color unevenness that occurs over time caused by over-coating the water-containing colored stucco composition are caused particularly by the color jump phenomenon of the colored stucco coating film. Therefore, the method for coloring the stucco composition of the present invention is useful not only for forming a colored stucco coating film without color skipping, but also for generating color difference due to overcoating and color unevenness over time after drying. It can be used effectively to control. In particular, according to the coloring method of the present invention, it is possible to provide a water-containing colored stucco composition which can be repair-applied with a tacky tap, in addition to being capable of recoating without color difference.

 As described above, the coloring method of the present invention is a method in which a colored stucco material, which has been conventionally prepared at the time of use (formulation and toning) in the field, has been previously toned, or has already been mixed with water. It can be used effectively to provide a stable state as a product, and even if it is applied, it does not jump out of color, and even if it is applied repeatedly, it can produce a reproduction of the desired color evenly without color unevenness and color difference. Can be used effectively.

Further, the method for suppressing the occurrence of color difference by re-coating of the present invention comprises: When applying as a coating film forming material, uniform color tone (chromaticity, hue) by suppressing the color difference (color difference between the undercoated surface and the overcoated surface) caused by seaming and repair. (Color) can be effectively used for forming a colored stucco coating film. That is, the method of the present invention can be effectively used for providing a water-containing colored stucco composition that can be repaired or overcoated.

 Furthermore, the method for suppressing color jump of a colored stucco coating film of the present invention is intended to suppress the whitening of a colored stucco coating film to form a coating film having a desired color. Can be effectively used to suppress the occurrence of color difference due to the difference in color, and to suppress the occurrence of color unevenness due to the time-dependent color jump of the colored stucco coating film. That is, the method for suppressing color jump of a colored stucco coating film of the present invention is useful for forming a colored stucco blocking film having a uniform tint (chromaticity, hue, and color).
