Embodiment 1

[0018] Embodiment 1, get dimethyl formamide 5% by weight, butanone 10%, butyl acetate 20%, ethyl acetate 6%, polyurethane resin 50%, particle diameter is the matting agent silicon dioxide 6 of 1.2 μm %, dispersant methyl amyl alcohol 1%, slip agent LA-322 1%, vehicle PT-4235 1%. The method for preparing above-mentioned matting coating composition is:

[0019] ① Add dimethylformamide, butanone, ethyl acetate, and butyl acetate into the dispersion tank, then add polyurethane resin, stir evenly, and completely dissolve the polyurethane resin;

[0020] ②Under constant stirring of the mixture, slowly add the matting agent and keep stirring for 60-90 minutes to make it evenly dispersed in the system;

[0021] ③Under stirring, add hand feeling agent, dispersant, vehicle and thickener in sequence, and continue stirring for 30-60 minutes to obtain slippery matte coating.

Embodiment 2

[0022] Embodiment 2, get dimethylformamide 3% by weight, butanone 13%, butyl acetate 20%, ethyl acetate 14%, polyurethane resin 42%, particle diameter is the matting agent silicon dioxide 4 of 1.4 μm %, dispersant methyl amyl alcohol 1%, cyanhydroxycellulose ethyl cellulose thickener 1%, vehicle MG-C 1%, astringent feel agent HM-4930 1%, the preparation method of the above-mentioned examples As described in Example 1, the astringent matting paint can be obtained.

Embodiment 3

[0023] Embodiment 3, get dimethylformamide 4% by weight, methyl ethyl ketone 10%, butyl acetate 25%, ethyl acetate 11.3%, polyurethane resin 43%, particle diameter is the matting agent silica 5 of 1.6 μm %, dispersant polyacrylamide 1.2%, vehicle PT-4235 1.2%, oily feel agent LA-351 1.3%, the preparation method of the above-mentioned examples is as described in Example 1 to obtain the oily matte coating.

Abstract

The invention relates to a chemical coating used for leather chemical industry and a preparation method thereof, in particular to a leather flatting coating composition and a preparation method thereof. The leather flatting coating composition comprises the following components in percentage by weight: 35 to 50 percent of polyurethane resin, 3 to 10 percent of dimethyl formamide, 10 to 15 percentof butanone, 20 to 30 percent of butyl acetate, 5 to 15 percent of acetic ether, 3 to 6 percent of flatting agent, 0.5 to 2 percent of handfeel agent, 0.5 to 2 percent of dispersant, 0.5 to 2 percentof color developing agent, and 0 to 1.5 percent of thickening agent. In addition, the invention also discloses the method for preparing the flatting coating. Compared with the common market coating, the flatting coating has the characteristics of wide application, high dullness, good transparency and good handfeel. The leather flatting coating composition is suitable for common leather surface treatment and high-grade leather surface treatment, and has lasting effects.

Description

technical field [0001] The invention relates to a chemical coating used in the leather chemical industry and a preparation method thereof, in particular to a leather matting coating composition and a preparation method thereof. Background technique [0002] The so-called leather matting paint refers to a substance with a suitable viscosity and can be uniformly covered on the leather surface by printing, roller coating, etc., so that the leather surface has weak or no reflective ability. [0003] Applying a layer of matting paint on the leather can make the leather look more authentic and more fashionable; but applying matting paint is likely to cover the original color of the leather, so the matting paint used on the leather surface on the market now, or matting The degree of transparency is good, but the transparency is poor, and the original color of the leather cannot be shown; or the transparency is good, but the extinction is not enough.
