Embodiment Construction

[0015] The specific technical scheme of the present invention will be further described below in conjunction with the given embodiment:

[0016] In the embodiment given in the present invention, include a kind of anti-aging matting paint for rubber rain boots made of ethylene propylene rubber and silicon dioxide, the specific formula and preparation process are as follows:

[0017] 1. Select the basic material ethylene propylene rubber density (g / cm 3 )0.860-0.870, refractive index (n 20 D) 1.476-1.488 and silica particle size (μm) 2.0-2.6, refractive index (n 20 D) 1.45, implemented according to the following formula:

[0018] (1) Ethylene-propylene rubber: 100 parts; silica: 40 parts; sulfur: 2.0 parts; accelerator: 3 parts; active agent: 4 parts; anti-aging agent: 3 parts; dispersant: 1 part; surface treatment agent: 1 part; leveling agent: 2.5 parts; solvent: 1800 parts.

[0019] (2) Ethylene-propylene rubber: 100 parts; silicon dioxide: 28 parts; sulfur: 0.8 parts; ac...

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...
