MULTI-LAYER ROLLED ZOLNER ZERO COVERING

The utility model relates to the field of laminated materials, in particular, to rolled polyvinyl chloride coating of zero in construction, usually called “linoleum.

In modern conditions, the most important operational and technical requirements for polymer materials for flooring are:

ensuring maximum industry, manufacturability and workability of coatings;

high physical and mechanical properties and physico-chemical parameters (wear resistance, stability of linear dimensions, low deformability under load, resistance to pollution, resistance to pollution and staining);

certain sanitary and hygienic indicators (low level of emissions of harmful substances; natural, low total toxicity for polyvinyl chloride floor coverings);

high decorative-aesthetic and heat and sound insulation properties, as well as low mass consumption of polymeric materials.

Abroad and in recent years in the Russian Federation, the most technologically advanced floor coverings are PVC foam floor coverings with a fiberglass backing such as “Cushioned vinyls” foam coatings from 3 to 4 meters wide, laid on the entire room with a single carpet without cutting individual sheets, excluding these additional operations. PVC flooring without a weld in the middle of the room is also more durable with the equality of other indicators. In the Russian Federation, such foamed PVC coatings have been produced since 1995 by the SZhZhO plant (before 2001 - SINTERROS) with a thickness of 1.4 to 3.0 mm and a width of 2 4 m.

However, often, in accordance with SNiP, the sound absorption index (reduction index of the reduced level of impact noise) should be 18 dB for heat absorption, the heat absorption coefficient of the floor surface should be no more than 10.0 10.8), while the thickness of the foamed PVC floor coverings should be at least 3.0 mm, usually 3.3 mm.

With such a large thickness of PVC foamed coatings of plasticized polyvinyl chloride, which has undergone heat treatment when foaming at a temperature of 200 ° C, the coating always contains decomposition products of the polyvinyl chloride composition that degrade the sanitary and hygienic properties and physicochemical parameters of the polymeric material and the use of foamed coatings of such a thickness PVC layer in residential areas is undesirable.

A competitor is also known as a rolled multilayer polymer new floor covering, which is a polyvinyl chloride floor covering with a compact polyvinyl chloride layer and a multi-color printed pattern on a needle-punched fibrous substrate made of polyester fibers with a total thickness of 2.7 mm, which has better sanitary and chemical properties, but the width of this coating is 3 , 0 and 3.5 m.

Known PVC flooring “The competitor is the closest analogue to the claimed flooring and is accepted by the applicant as a prototype.

The disadvantages of the known coating include the fact that the “Competitor” PVC coating is made on a heat-sensitive (to a high temperature in a heat chamber) basis of polyester fibers using standard promaznoy technology, and as a result, a coating of 4 m width is not made and cannot be made due to shrinkage in the heat chamber.

Also, due to the thermal sensitivity of the base, the temperature in the heat chamber cannot be raised to 220 ° C due to shrinkage of the base and therefore, coatings with an upper foamed decorative relief pattern are not produced, as in foamed type “Cushioned vinyls.

In addition, the thickness of the polymer coating “Competitor 2.7 mm is insufficient to obtain thermal and acoustic insulation performance indicators that meet the requirements of SNiP.

PVC flooring with a decorative relief pattern that imitates the structure of wood, stone, etc., with improved sanitary and chemical properties, i.e. with a smaller thickness of the needle-punched polymer layer up to 4 m wide, the Russian market needs LNG countries, as one of the main residential construction rooms is 3.6 and 4.0 m.

In the proposed coating, these drawbacks of analogues, including the prototype, are eliminated due to the fact that the multilayer rolled polymer floor covering in the structure of the lower polyvinyl chloride layer contains fiberglass, and as part of the polyvinyl chloride layers of the claimed coating, one layer is foamed with a decorative relief pattern.

The inventive coating is also characterized in that the upper polymer layer consists of several at least two or three polyvinyl chloride layers, while the upper layer is made of protective wear-resistant thickness of 0.12 - 0.50 mm, the lower structure of which contains fiberglass or mineral paper with a thickness of 0.6 1.0 mm, and foamed (in the case of a coating with a decorative relief pattern) with a thickness of 0.3 0.5 mm. As the lower layer of the claimed coating can be used non-woven needle-punched material of polyester polypropylene fibers (or mixtures thereof) by weight of 200 360 g / m

The invention is illustrated in FIG. 1,2,3 and 4., where figure 1 shows the claimed coating in cross section, consisting of 4 layers (front transparent layer, the middle foam layer with a multicolor decorative relief pattern, a compact layer containing fiberglass in its structure, the lower layer - the basis of non-woven needle-punched

material from polyester fibers), where Fig. 2 shows the claimed coating in cross section, consisting of 4 layers (front transparent layer, middle foam layer with multicolor decorative relief pattern, compact layer containing mineral paper in its structure, lower layer - basis of non-woven needle-punched material from a mixture of polyester and polypropylene fibers), Fig. 3 shows the claimed coating in cross section, consisting of 3 layers (front transparent layer, lower compact layer with multicolor decor tive relief pattern, comprising in its structure a glass fiber, the bottom layer - the basis of the needled nonwoven material of polyester fibers), as in Figure 4 - a table of properties of the claimed coatings compared with known, used in building coatings.

The inventive consists of 2 or 3 of the upper polyvinyl chloride layers and the lower layer - the basis of non-woven needle-punched material, while the lower of the polyvinyl chloride layers contains fiberglass in its structure, which allows to obtain dimensionally stable coatings with a given width of up to 4 m, as well as receive such coatings with a foamed middle polyvinyl chloride layer with a multi-color decorative relief pattern.

The claimed coating inherently represents a new construction of polymer linoleum, which can be implemented in enterprises producing PVC flooring, as follows:

Example I

1. At the first stage, the top layer of the polymer floor covering is made, consisting of three polyvinyl chloride layers and fiberglass, in the following ways, for example:

- by applying a primer layer of plastisol PVC composition weighing 550-600 g / m and gelation by heat treatment on a heated drum (cylinder) at a temperature of 130-140 ° C to obtain a lower compact layer with a thickness of 0.6 mm;

-application of a middle layer of plastisol PVC composition containing a blowing agent - porphore CHKhZ-21 in the amount of 360 g / m and its heat treatment on a heated drum (cylinder) at a temperature of 130-140 ° C for preliminary gelation of the middle layer;

-application on the middle layer of a multicolor printed drawing by intaglio printing inks containing a foaming inhibitor;

-applying a transparent (protective) front layer of PVC complastizol compositions in an amount of 350 g / m and heat treatment of all three layers in a heat chamber at temperatures of 200 - 220 ° C with foaming of the middle layer with the formation of a decorative relief pattern due to the action of the foaming inhibitor in paints;

- cooling of the upper polymer layer with a thickness of 1.5 - 1.6 mm and winding into a large roll with a width of 4100 mm.

fibers by weight 360 g / m with the upper polymer layer obtained on the first.

An adhesive layer of the PVC plastisol composition is applied to the back side of the upper polymer layer and combined with the base - needle-punched non-woven material with a width of 4100 mm, and then the doubled coating is heat treated on a heated cylinder with a diameter of 1.8 - 2.0 m at a temperature of 140-160 ° C .

The thus formed 3.3 mm thick multilayer polymer coating web is cooled to a temperature of 20 - 23 ° C, the edges are trimmed to a material width of 4000 mm and cut into cross rolls on measuring rolls 25 m long each.

Example II

1. At the first stage, an upper layer of polymer flooring is made, consisting of two polyvinyl chloride layers and mineral paper as a reinforcing material, in the following ways, for example:

- by applying a layer of GHS of a plastisol composition with a weight of 800 g / m, containing the ChHZ-21 porophore, for foaming this layer and its heat treatment (preliminary gelation) on heated cylinders at a temperature of 130 - 140 ° С;

-application on this layer of a multi-color printed drawing by intaglio printing with inks containing a foaming inhibitor;

-applying a transparent (protective) face layer of PVC plastisol compositions in an amount of 250 g / m and heat treatment of two layers in a heat chamber at temperatures of 200 220 ° C with foaming of the lower layer with the formation of a decorative relief pattern due to the action of the foaming inhibitor in paints;

- cooling of the upper polymer layer with a thickness of 1.7 1.8 mm and winding into a large roll with a width of 4100 mm.

2. At the second stage, the upper polymer layer is duplicated with the base of needle-punched non-woven material from a mixture of polyester and polypropylene fibers (in the ratio of 80% - 20%) by weight of 250 t / m with the upper polymer layer obtained in the first stage.

On the back side of the upper polymer layer, an adhesive layer of the PVC plastisol composition is applied and combined with the base - needle-punched non-woven material with a width of 4100 mm, and then the doubled coating is heat treated on a heated cylinder with a diameter of 1.8 - 2.0 m at a temperature of 140 160 ° С.

The 3.0 mm thick multilayer polymer coating web thus formed is cooled to a temperature of 20 - 23 ° C, the edges are trimmed to a material width of 4000 mm and cut into cross rolls on measuring rolls 25 m long each.

nenny because Compared to fiberglass, mineral paper is denser, less porous, impregnated with latex, and a layer containing porophore can be immediately applied to it.

When using fiberglass, a porous material, fiberglass as the reinforcing base, it is necessary to impregnate the fiberglass with the composition of PVC plastisol in the first stage to displace air from it (the presence of air will lead to the formation of large bubbles when foaming the coating).

After obtaining a compact lower layer reinforced with fiberglass, a plastisol layer containing a porophore can be applied to it to form a foamed layer with a relief pattern.

According to the proposed utility model formula, it is also possible to produce coatings up to 4 m wide inclusive with a compact top layer consisting of two polyvinyl chloride layers of which the bottom is reinforced with fiberglass or mineral paper 2.7, 3 mm thick.

The inventive device of a multilayer roll polymer floor covering, consisting of 3 layers with a thickness in a certain ratio, due to the use in the structure of the lower compact polyvinyl chloride layer as a reinforcing material of fiberglass or mineral paper, works as a single design and allows to improve its decorative, aesthetic and heat and sound insulation properties and ensure the preservation of these properties during the further operation of the coating for a long time.

Comparative physico-mechanical characteristics of the claimed coating and known manufactured products are shown in the table (Fig. 4), from which it follows that the inventive multilayer rolled polymer floor covering is characterized not only by the best indicators (total toxicity, sound absorption, heat absorption), but also allows to achieve the required performance in accordance with SNiP.

Thus, the claimed device due to the introduction of a reinforcing base-fiberglass or mineral paper into the structure of the material allows you to create the optimal floor covering design with improved sanitary and hygienic characteristics, heat and sound insulation properties, significantly increase its wear resistance and durability, maintain heat and sound insulation properties throughout the entire life cycle, corresponding to requirements for PVC floor coverings laid directly on concrete in accordance with applicable laws and regulations.
