Description

Resin for textured coatings {RESIN FOR SOFT FEEL COATING}

The present invention relates to a resin for texture coating, and more particularly to an acrylic resin for texture coating with improved physical properties.

Textured resin is a paint for polymer or textured paint that increases the added value by stimulating the sensibility through the touch in addition to the physical and aesthetic functions such as satisfying the simple gloss, color, or protective hardness of the top coat or protective coating layer. I'm talking about Suzy.

Textured resins are actively applied to high value-added consumer goods markets, such as mobile phones and automobiles, which require long contact time with human bodies and require aesthetic and emotional expression, and exterior materials of various products. Therefore, the texture is important, but the characteristics such as stain resistance and wear resistance should be excellent.

However, conventional polymers for texturing are disadvantageous due to the deterioration of the basic physical properties of the coating film generated to exhibit a smooth texture. Therefore, by solving the trade off relationship between the texture and the basic physical properties, it remains difficult to improve the physical properties while maintaining the texture. In addition, although a polycarbonate resin or the like was conventionally used, there was a problem in that the raw material cost was high. Therefore, while reducing the cost, there is a need for a competitive technology that is superior in quality compared to the conventional texture resin.

One object of the present invention is to provide a resin for a texture paint, which is cost-saving and maintains a smooth texture while improving physical properties such as heat yellowing resistance, stain resistance, alcohol resistance, and wear resistance.

(stearyl methacrylate), hydroxyethyl acrylate (hydroxyethyl acrylate), alpha methyl styrene dimer (α-methyl styrene dimer) and may be prepared using organic peroxides (organic peroxides).

Resin for a textured paint for another object of the present invention is a first step of putting a first mixed solution containing a solvent and an acrylic monomer in a reactor to increase the temperature to 100 ℃ or more; A second step of adding a second mixed solution containing an acrylic monomer to the reactor; Adding a third mixed solution including the solvent and the organic peroxide to the reactor; A fourth step of cooling below 90 ° C; And a fifth step of dilution and filtration.

In one embodiment, the first mixed solution may include toluene and n-butyl acetate.

In one embodiment, the acrylic monomer of the second mixed solution may include at least one or more of a monomer including a hydroxyl group, a monomer showing hydrophobicity, and a mixture thereof.

In one embodiment, the second mixed solution may include an acrylic monomer, an initiator, and a crosslinking regulator. In one embodiment, the acrylic monomer of the second mixed solution may be the same acrylic monomer as the acrylic monomer of the first mixed solution, may be another kind of acrylic monomer, or a mixture thereof.

The results of analyzing the examples prepared according to one embodiment of the present invention are shown below.

1 is a view showing the analysis results of the resin for texture paint prepared according to the embodiment. 1, the GPC molecular weight measurement result confirmed that the weight average molecular weight (MW) was 6200, and the number average molecular weight (MP) was 5453. In the case of Example 1, the synthesis was found to be stable in the synthesis process, and as a result of measuring the basic physical properties, it was confirmed that the solid content (NV) was 40 to 50%, the viscosity was 470 to 4800 csp, and the appearance was transparent and stable, and Tg Was 25 ° C., OH% (hydroxy%) was 1.5%, and hydrophobicity was 55%. In addition, samples 1 to 3 were made using the resin prepared in Example 1, and each physical property test was performed to show in Table 1 below. It can be seen that the resin for the textured paint prepared according to Example 1 exhibits an appropriate viscosity, softness, hardness and wear resistance.

In the case of the resin prepared through Examples 2 and 3, the synthesis was made stable, and in Example 2, solid content was 50%, viscosity 3700 cps, Tg was 16 ° C., hydroxy ratio was 1.57%, and In the case of Example 3, it was found that the solid content was 50%, the viscosity was 2700 cps, the Tg was 84 ° C., and the hydroxy ratio was 0.25%. In Examples 2 and 3 it was confirmed that by adding a monomer containing a hydroxyl group both physical properties and paint properties are increased.

In Example 4, the synthesis was stable, and it was found that the solid content was 50%, the viscosity was 2300 cps, the Tg was -11 ° C, the hydroxy ratio was 1.5%, and the hydrophobicity was 22%. In Example 4, the viscosity was reduced by about 2 times compared to that of Example 1. This seems to be due to the high dose of Tg and hydrophobic monomer.

In Example 5, the solid content was found to be 50% and the viscosity was 4200 cps. Example 5 was found to have no problem in the synthesis process but the viscosity was too high.

Specifically, FIG. 2 shows physical property analysis data according to hydrophobic content. When the hydrophobicity is 30% or less, the alcoholic and abrasion properties are reduced compared to the texture. Able to know. 2, when the hydrophobic content is 30 to 55%, the texture, the alcohol resistance and the wear resistance may all be excellent, and in the case of Example 4, the hydrophobicity is lower, so the texture is softer but the alcohol resistance and the wear resistance are In the case of Example 5, although alcohol resistance and abrasion resistance were improved, it can be seen that the soft texture was reduced.
