Anti-aging antiglossing pigment and preparation thereof

Abstract

The invention discloses an aging resistant light extinction coating and a preparation method thereof, which belong to the technical field of macromolecular material utilization and coating, and, in particular relate to an aging resistant light extinction coating technology used in rubber boot surface and an improvement in the preparation method. The invention provides the aging resistant light extinction coating with excellent aging resistance and fluidity and a preparation process thereof. The rubber boot aging resistant light extinction coating is made from ethylene propylene rubber and silicon dioxide, and the preparation method comprises the following steps: 1, the following formula is adopted and includes: 100 portions of ethylene propylene rubber, 20 to 50 portions of silicon dioxide, 0.3 to 4.0 portions of vulcanizing agent, 2 to 15 portions of accelerant, 2 to 10 portions of activating agent, 0.5 to 5.5 portions of protection additive, less than 0.1 to 5 portions of dispersant, less than 0.1 to 5 portions of surface treatment agent, less than 0.1 to 5 portions of flatting agent and less than 1,000 to 4,500 portions of solvent; and 2, the materials in the formula are added in a grinding device for grinding, and the grinding time and dispersing process of silicon dioxide are controlled so that the silicon dioxide can be evenly dispersed; after grinding, the solvent is adopted to adjust the mixture to an appropriate concentration, and the aging resistant light extinction coating used in rubber boot can be obtained after filtration.

Description

Technical field: [0001] The invention belongs to the technical field of polymer material utilization and paint, and in particular relates to an aging-resistant matting paint technology and preparation method improvement applied on the surface of rubber rain boots. Background technique: [0002] This year, with the continuous improvement of people's living standards, consumers' aesthetic views are more and more inclined to leisure, fashion and personalization, which makes the application of matting coatings very extensive. Especially in the rubber rain boots industry, the proportion of products using matting coatings has also increased year by year. At present, there are mainly two matting coating technologies used in China: 1. Imported base materials such as D-LAC HY-510 produced in Japan and D-LAC HY-510 produced in Korea. -LAC HY-415 and other matting coatings made by adding matting agent or silica; 2. Coatings made by using SBS thermoplastic elastomer material as the base...

AI Technical Summary

Problems solved by technology

1. Due to the influence of the mechanism of the imported base material itself and the vulcanization temperature and other conditions, the vulcanized matte coating has the following disadvantages: the aging resistance of the paint film is not good; the surface of the paint film turns yellow seriously; the poor flow of the paint leads to serious flow marks

2. Problems such as dispersion and sedimentation of silica have not been completely resolved, and the aging resistance and fluidity of this coating are not good
