Embodiment 1

[0018] Example 1. Take 5% by weight of dimethylformamide, 10% of methyl ethyl ketone, 20% of butyl acetate, 6% of ethyl acetate, 50% of polyurethane resin, and silica 6 as a matting agent with a particle diameter of 1.2μm. %, dispersant methyl amyl alcohol 1%, slippery feel agent LA-322 1%, vehicle PT-4235 1%. The method for preparing the above matting coating composition is:

[0019] ①Put dimethylformamide, methyl ethyl ketone, ethyl acetate, and butyl acetate into the dispersion tank, then add the polyurethane resin, stir evenly, so that the polyurethane resin is completely dissolved;

[0020] ②While the mixture is constantly stirred, slowly add the matting agent and keep stirring for 60 to 90 minutes to make it evenly dispersed in the system;

[0021] ③While stirring, add the hand-feeling agent, dispersant, coloring agent, and thickening agent in sequence, and continue to stir for 30 to 60 minutes to obtain slippery matte paint.

Embodiment 2

[0022] Example 2, Take 3% dimethylformamide, 13% methyl ethyl ketone, 20% butyl acetate, 14% ethyl acetate, 42% polyurethane resin, and a matting agent silica 4 with a particle diameter of 1.4μm in weight ratio. %, dispersant methyl pentanol 1%, cyanohydroxycellulose ethyl vinyl vinculin thickener 1%, vehicle MG-C 1%, astringent feel agent HM-4930 1%, the preparation method of the above embodiment As described in Example 1, the astringent matting paint can be obtained.

Embodiment 3

[0023] Example 3 Take 4% dimethylformamide, 10% methyl ethyl ketone, 25% butyl acetate, 11.3% ethyl acetate, 43% polyurethane resin, and a matting agent silica 5 with a particle diameter of 1.6μm in weight ratio. %, dispersant polyacrylamide 1.2%, vehicle PT-4235 1.2%, oily feel agent LA-351 1.3%, the preparation method of the above embodiment is as described in Example 1 to obtain an 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 percent of 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 percent of 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, and more specifically to a leather matting coating composition and a preparation method thereof. Background technique [0002] The so-called leather matting coating refers to a substance with suitable viscosity and capable of evenly covering the leather surface by printing, roller coating, etc., so that the leather surface has weak or non-reflective ability. [0003] Applying a layer of matting paint on the leather can make the leather look more genuine and fashionable; but applying matting paint is likely to cover the original color of the leather, so now the matting paint used on the leather surface on the market, or matting The degree is good, but the transparency is poor, and the original color of the leather cannot be displayed; or the transparency is good, but the extinction degree is not enough. Summary of the invention [0004] The purpo...
