Description

  TECHNICAL FIELD The present invention relates to a room-temperature drying type solvent-based soft-feel coating material, and a paint and a coating film using the same, and more specifically, mainly automobile interiors; resin molded products indoors and outdoors; stairs, floors, furniture. The present invention relates to a room-temperature dry solvent-based soft-feel paint material that can be applied to woodwork products and the like, paints using the same, and coating films.

Conventionally, products that are frequently touched, for example, automobile interior parts such as power window finishers and audio switches, and eyeglass cases have been subjected to surface treatment to give a soft feeling (for example, Patent Document 1). reference.).
In addition, soft feel paint is often used in European cars, and recently its application is increasing in Japan.
Japanese Patent Laid-Open No. 2-174976

Two-component urethane paints are mainly used for coating used for these surface treatments, and solvent-based and water-based coatings are known (for example, see Patent Documents 2 and 3).
In such painting, undercoating is applied to improve adhesion, and soft feel paint is thickened or baked so that scratches, sweat, and cosmetics do not occur when nails, rings, etc. are rubbed. Countermeasures for suppressing the penetration of chemicals and the like are performed by increasing the temperature or increasing the baking time.

  However, due to such a response, not only the cost is increased but also the productivity is decreased.

  The present invention has been made in view of such problems of the prior art, and the object of the present invention is a room temperature dry solvent system that can provide a soft touch even with a normal coating method or film thickness. An object of the present invention is to provide a material for soft feel paint, and a paint and a coating film using the same.

  As a result of intensive studies to achieve the above object, the present inventors have found that the above object can be achieved by using a lipophilic polyrotaxane in which a linear molecule or a cyclic molecule is hydrophobic. It came to be completed.

  That is, the room temperature drying type solvent-based soft feel coating material of the present invention includes a cyclic molecule, a linear molecule that claws the cyclic molecule in a skewered manner, and the cyclic molecule disposed at both ends of the linear molecule. And at least one of the linear molecule and the cyclic molecule is composed of a lipophilic polyrotaxane having a hydrophobic property.

  The room temperature drying solvent-based soft-feel paint of the present invention contains the coating material of the present invention, that is, the lipophilic polyrotaxane described above, preferably in a mass ratio of 30 to 80% with respect to the coating film forming component. Features.

  Furthermore, the soft feel coating film of the present invention is characterized by solidifying the above-mentioned room temperature drying solvent-based soft feel paint of the present invention.

  Furthermore, the laminated coating film of the present invention is characterized in that a coating film using a room temperature drying type solvent-based soft feel coating is formed on an object to be coated.

  According to the present invention, since a lipophilic polyrotaxane in which linear molecules and cyclic molecules are hydrophobic is used, a soft tactile sensation can be obtained even with a normal coating method and film thickness.

  Hereinafter, the room temperature dry type solvent-based soft feel coating material of the present invention, the coating material using the same, and the coating film will be described in detail. In the present specification, “%” represents mass percentage unless otherwise specified.

As described above, the room temperature dry solvent-based soft feel coating material of the present invention is composed of an oleophilic polyrotaxane modified to a room temperature dry type that dissolves in a solvent.
The room temperature dry solvent-based soft-feel paint of the present invention contains the above-mentioned material, that is, a lipophilic polyrotaxane.

FIG. 1 is a schematic diagram conceptually showing a hydrophobic modified polyrotaxane.
In this figure, this hydrophobic modified polyrotaxane 1 has a linear molecule 2, a cyclodextrin 3 that is a cyclic molecule, and a blocking group 4 disposed at both ends of the linear molecule 2. The molecule 2 penetrates the opening of the cyclic molecule 3 and includes the cyclic molecule 3.
And cyclodextrin 3 has the hydrophobic modification group 3a.

By using such a lipophilic polyrotaxane, it is possible to obtain a soft feel coating material that is miscible with a hydrophobic solvent. Moreover, when applied to a paint, a coating film having a soft feeling can be obtained.
The “soft-feel paint” refers to a paint that provides a soft touch such as a rubber touch or a suede tone.

In the present invention, one or both of the cyclic molecule 2 and the linear molecule 3 have hydrophobicity, and the lipophilic polyrotaxane showing lipophilicity as a whole, typically the cyclic molecule 2 has a hydroxyl group, A lipophilic polyrotaxane in which all or part of the hydroxyl groups of the cyclic molecule are modified with a hydrophobic modifying group is used, and the polyrotaxane becomes soluble in the solvent described later, and is used as a component of the solvent-based paint. It becomes possible to mix.
When the soft feel coating material of the present invention comprising such a lipophilic polyrotaxane is mixed with another polymer, pseudo-crosslinking occurs due to van der Waals force, etc., and both of them behave as a composition or a compound. Conceivable. In this case, it is considered that at least the polyrotaxane exhibits the pulley effect described above.

In the present invention, the modifying group exhibiting hydrophobicity has a hydrophobic group or a hydrophobic group and a hydrophilic group, and may be hydrophobic as a whole.
Examples of the hydrophobic group include an alkyl group, a benzyl group (benzene ring) and a benzene derivative-containing group, an acyl group, a silyl group, a trityl group, a nitrate ester group, and a tosyl group.
Examples of the hydrophilic group include a carboxyl group, a sulfonic acid group, a sulfate ester group, a phosphate ester group, an amino group (primary to tertiary), a quaternary ammonium base, and a hydroxyalkyl group.

The cyclic molecule in the lipophilic polyrotaxane is not particularly limited as long as it is included in the linear molecule as described above and exhibits a sliding effect, and various cyclic substances can be exemplified. Many cyclic molecules have a hydroxyl group.
In addition, it is sufficient that the cyclic molecule is substantially cyclic, and it is not necessarily required to be completely closed like “C” shape.

Furthermore, as the cyclic molecule, those having a reactive group are preferable, and this facilitates the binding with the above-described hydrophobic modifying group.
Examples of such a reactive group include, but are not limited to, a hydroxyl group, a carboxyl group, an amino group, an epoxy group, an isocyanate group, a thiol group, and an aldehyde group. In addition, as a reactive group, when forming the blocking group mentioned later (blocking reaction), the group which does not react with this blocking group is preferable.

In addition, the degree of modification by the hydrophobic modifying group of the cyclic molecule in the lipophilic polyrotaxane used in the present invention may be 0.02 or more when the maximum number of hydroxyl groups that the cyclic molecule can be modified is 1. Preferably, it is 0.04 or more, more preferably 0.06 or more.
That is, when the modification degree is less than 0.02, the solubility in a solvent is not sufficient, and insoluble bumps (protrusions derived from foreign matter adhesion, etc.) may be generated.

  The maximum number of hydroxyl groups that can be modified in the cyclic molecule means the total number of hydroxyl groups that the cyclic molecule had before modification. The degree of modification is, in other words, the ratio of the number of modified hydroxyl groups to the total number of hydroxyl groups.

  Furthermore, when the polyrotaxane has a large number of cyclic molecules, it is not necessary that all or a part of the hydroxyl groups of each cyclic molecule is modified with a hydrophobic modifying group. In other words, as long as the entire polyrotaxane exhibits lipophilicity, there may be no problem even if a cyclic molecule having a hydroxyl group that is not modified with a hydrophobic modifying group is partially present.

As a method for introducing the hydrophobic modifying group, the following method can be employed.
For example, cyclodextrin is used as a cyclic molecule of polyrotaxane, and an isocyanated PEG-monostearate composed of hexamethylene diisocyanate and PEG-monostearate is reacted with the hydroxyl group of the cyclodextrin. The modification rate can be arbitrarily controlled by changing the addition amount of the isocyanated PEG-monostearate at this time.

In the lipophilic polyrotaxane, the number (inclusion amount) of the cyclic molecule included in the linear molecule is 0 when the maximum inclusion amount that the linear molecule can include the cyclic molecule is 1. 06-0.61 are preferable, 0.11-0.48 are still more preferable, and 0.24-0.41 are still more preferable.
That is, if this ratio is less than 0.06, the pulley effect is insufficient, the elongation percentage of the coating film is lowered, and the soft feeling may be insufficient. If it exceeds 0.61, the cyclic molecules are arranged too densely, the mobility of the cyclic molecules is lowered, the elongation rate of the coating film is similarly lowered, and the soft feeling tends to be insufficient.

Further, the amount of inclusion of the cyclic molecule can be controlled as follows.
For example, to DMF (dimethylformamide), a BOP reagent (benzotriazol-1-yl-oxy-tris (dimethylamino) phosphonium hexafluorophosphate), HOBt, adamantaneamine, and diisopropylethylamine are added in this order. To do. On the other hand, a solution is obtained in which a clathrate complex in which a cyclic molecule is skewered into a linear molecule is dispersed in a DMF / DMSO (dimethyl sulfoxide) mixed solvent. By mixing these two and changing the mixing ratio of DMF / DMSO at this time, the inclusion amount of the cyclic molecule can be arbitrarily controlled. In addition, the higher the DMF / DMSO ratio, the greater the amount of inclusion of the cyclic molecule.

  Specific examples of the cyclic molecule include various cyclodextrins such as α-cyclodextrin (glucose number: 6), β-cyclodextrin (glucose number: 7), and γ-cyclodextrin (glucose number: 8). ), Dimethylcyclodextrin, glucosylcyclodextrin and derivatives or modified products thereof, and crown ethers, benzocrowns, dibenzocrowns, dicyclohexanocrowns and derivatives or modified products thereof.

The above-mentioned cyclic molecules such as cyclodextrin can be used alone or in combination of two or more.
Of the various cyclic molecules described above, α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin are particularly preferable, and in particular, α-cyclodextrin is used from the viewpoint of inclusion. Is preferred.

On the other hand, the linear molecule may be substantially linear, and may have a branched chain as long as the cyclic molecule that is a rotor can be included so that it can rotate and exert a pulley effect. .
Further, although it is affected by the size of the cyclic molecule, its length is not particularly limited as long as the cyclic molecule can exert a pulley effect.

In addition, as a linear molecule, what has a reactive group in the both ends is preferable, and it becomes possible to react this with the said blocking group easily by this.
Such a reactive group can be appropriately changed according to the type of blocking group employed, and examples thereof include a hydroxyl group, an amino group, a carboxyl group, and a thiol group.

Such a linear molecule is not particularly limited, and is a polyester having a polyalkylene, polycaprolactone, or the like, a polyether such as polyethylene glycol, a polyamide, a polyacryl, or a linear chain having a benzene ring. Can be mentioned.
Among these linear molecules, polyethylene glycol and polycaprolactone are particularly preferable, and polyethylene glycol is preferably used from the viewpoint of solubility in water or a solvent.

Further, the molecular weight of the linear molecule is preferably 1,000 to 100,000, preferably 10,000 to 60,000, and more preferably 30,000 to 50,000. preferable.
That is, when the molecular weight of the linear molecule is less than 1,000, the pulley effect is lowered, and the elongation percentage of the coating film is lowered, and the soft feeling may be insufficient. When it exceeds 100,000, the paintability is lowered, and the appearance such as smoothness may be lowered after painting.

On the other hand, the blocking group may be any group as long as it is arranged at both ends of the linear molecule as described above and can keep the cyclic molecule pierced by the linear molecule. It can be a group.
Examples of such a group include a group having “bulkiness” or a group having “ionicity”. Here, the “group” means various groups including a molecular group and a polymer group.

Examples of the group having “bulkyness” include a spherical shape and a side wall-shaped group.
In addition, the ionicity of the group having “ionicity” and the ionicity of the cyclic molecule interact with each other, for example, repelling each other, so that the cyclic molecule is skewed into a linear molecule. Can be held.

  Specific examples of such blocking groups include dinitrophenyl groups such as 2,4-dinitrophenyl group and 3,5-dinitrophenyl group, cyclodextrins, adamantane groups, trityl groups, fluoresceins and pyrenes. And derivatives or modified products thereof.

Here, the manufacturing method of the lipophilic polyrotaxane used for this invention is demonstrated.
As mentioned above, the lipophilic polyrotaxane is
(1) mixing a cyclic molecule and a linear molecule, penetrating the opening of the cyclic molecule in a skewered manner with the linear molecule, and including the cyclic molecule in the linear molecule;
(2) a step of preparing both the ends of the obtained pseudopolyrotaxane (both ends of the linear molecule) with a blocking group so that the cyclic molecule is not detached from the skewered state;
(3) a step of modifying the hydroxyl group of the cyclic molecule of the obtained polyrotaxane with a hydrophobic modifying group,
Is obtained by processing.

  In the step (1), the lipophilic polyrotaxane can also be obtained by using a hydroxyl group of the cyclic molecule that has been modified with a hydrophobic modifying group in advance. In that case, the step (3) is performed. Can be omitted.

It is preferable to be contained in an amount of 30 to 80% in terms of mass relative to the components (resin solid content and the like). More preferably, it is 40 to 80%, and particularly preferably 50 to 70%.
That is, when the content of the lipophilic polyrotaxane with respect to the coating film forming component is less than 30%, the pulley effect of the polyrotaxane cannot be sufficiently obtained, and the elongation percentage of the coating film is lowered and the elongation percentage of the coating film is lowered. However, the soft feeling may be insufficient. If it exceeds 80%, a sticky feeling may occur, and the paintability may deteriorate.

The room temperature dry solvent-based soft feel paint of the present invention preferably contains the above-mentioned lipophilic polyrotaxane in an existing room temperature dry solvent-based soft feel paint such as acrylic lacquer, cellulose lacquer, urethane resin paint, etc. It is obtained by blending so as to be an amount.
In other words, a normal temperature drying type solvent-based soft-feel coating material of the present invention, that is, a lipophilic polyrotaxane, a resin component, an additive, a pigment, a brightening agent or a solvent, and an arbitrary combination thereof are conventionally used. Can be blended and mixed on the basis.

Two or more of these may be mixed as appropriate. Moreover, even if some aqueous solvents, such as water and a butyl cellosolve acetate, are contained, it should just be considered as an organic solvent as a whole.

Furthermore, the soft feel paint can be a transparent color, a colored transparent color, an enamel color or a matte color.
In order to obtain a colored transparent color, an organic color pigment, an inorganic color pigment, and a dye may be added.

Example 1
1. Synthesis of Modified Polyrotaxane After binding 6 g of hexamethylene diisocyanate to 20 g of PEG-monostearate (manufactured by TCI) in toluene, purification was performed by recrystallization with ether.
15 g of the obtained isocyanate-modified PEG-monostearate was reacted with polyrotaxane (about 500 mg) dissolved in DMSO overnight at room temperature, and then purified by reprecipitation with ether and dried.

2. Preparation of Soft Feel Paint (Enamel Paint) The obtained polyrotaxane was dissolved in toluene so as to be 10%.
On the other hand, 200 g of CMCAB (CMCAB-641-0.5 manufactured by EASTMAN CHEMICAL) was added to 300 g of buticerorubu (ethylene glycol monobutyl ether) with stirring, and a water / amine mixture (water 498.09 g / dimethylaminoethanol 1. 91 g) was poured into the CMCAB solution to prepare a resin solution to 50%. In addition, an enamel paint was obtained by dispersing a pigment in the resin solution.

3. Formation of multi-layer coating film Cathodic electrodeposition paint (trade name “Power Top U600M”, cation-type electrodeposition paint manufactured by Nippon Paint Co., Ltd.) is applied to a 0.8 mm thick, 70 mm × 150 mm thick steel plate treated with zinc phosphate. After electrodeposition coating so that the thickness was 20 μm, baking was performed at 160 ° C. for 30 minutes.
Thereafter, a gray undercoat (trade name: Hyepico No. 500) manufactured by Nippon Oil & Fats Co., Ltd. was applied with 30 μm and baked at 140 ° C. for 30 minutes.
Next, 50 μm of a soft feel paint to which a modified polyrotaxane was added was applied.

(Examples 2 to 12, Comparative Example 1)
A laminated coating film was formed by repeating the same operation as in Example 1 except that the specifications shown in Table 1 were adopted.

  About the obtained laminated coating film, evaluation of the following (1)-(3) was performed.

(1) Soft feeling It judged with the touch as follows.
◯: Very soft feeling Δ: Some soft feeling ×: No soft feeling at all

(2) Adhesiveness Two coated plates were overlapped, and only one of the coated plates was held, and whether or not the other coated plate fell was judged.
○: Drops immediately △: Drops after a while ×: Does not fall at all

(3) Smoothness The smoothness of the soft feel coating film was visually evaluated.
◯: Pretty smooth Δ: Slightly uneven ×: Uneven

As is clear from the results in Table 1, it was confirmed that the soft feel coatings of Examples 1 to 8 according to the present invention were excellent in softness due to the pulley effect of polyrotaxane. Moreover, the external appearance was also favorable.
Moreover, it turned out that a soft feeling falls when the molecular weight of a linear molecule becomes less than 1000 like the soft feel coating film of Example 9. As in the soft-feel coating film of Example 10, when it exceeded 100,000, it was found that the tackiness and smoothness deteriorate.
Furthermore, it was found that when the amount added to the paint was less than 30% and more than 80% as in the soft feel coating film of Example 11, the soft feeling was lowered.

  On the other hand, when the modified polyrotaxane was not used as in Comparative Example 1, it was found that a soft feeling could not be obtained.

  As described above, according to the present invention, the desired appearance can be obtained with the same workability as that of normal coating without being limited to the narrow coating conditions specified in particular, and the soft feeling can be improved.
