Abstract

The invention relates to the technical field of silicone rubber, and particularly discloses matte silicone rubber for silk screen printing and a preparation method thereof.The matte silicone rubber is composed of a component A and a component B; the component A comprises vinyl-terminated silicone oil, methyl silicone oil, modified fumed silica, hollow microspheres, silicon dioxide, a silane coupling agent, a solvent and a platinum catalyst; the component B comprises vinyl-terminated silicone oil, methyl silicone oil, modified fumed silica, hollow microspheres, a silane coupling agent, a solvent, silicon dioxide, hydrogen-containing silicone oil and an inhibitor; the matte silicone rubber is prepared by mixing the component A and the component B according to the ratio of 1: (0.8-1.2), and by adopting the hollow microspheres and the modified fumed silica, the prepared matte silicone rubber has the advantages of being high in adhesion, resistant to friction and lasting in matte effect.

Description

technical field [0001] The application relates to the technical field of silicone rubber, more specifically, it relates to a matte silicone rubber for silk screen printing and a preparation method thereof. Background technique [0002] Screen printing silicone is a kind of liquid silicone used for printing. It can be firmly adhered to the surface of textiles through screen printing. Liquid silicone can reflect different printing effects by adding additives with different properties. Among them, the matte effect of silk screen printing silicone Because of its smooth surface, non-sticky surface, easy to clean and other advantages, it is loved by consumers. [0003] Usually, in order to achieve the matte effect of liquid silicone, matting powder is added to achieve the matte effect of silicone rubber, but the matting effect of matting powder is insufficient, and the matte surface after silk printing has poor wear resistance, and the silk screen layer of silicone rubber is easy ...
