Abstract

Belonging to the technical field of new material processing, the invention particularly relates to a heat-conducting anti-static silica gel product and a micro-injection molding process thereof. The heat-conducting anti-static silica gel product is prepared from the following raw materials by weight through micro-injection molding process: 100 parts of double-component liquid silica gel, 7-15 parts of polyimide, 4-10 parts of carbon nanotubes, 5-10 parts of diphenyl silanediol, 4-12 parts of nano-silica, 1-4 parts of an anti-static agent, 1-4 parts of hydroxymethyl cellulose, 5-12 parts of deionized water and 0.5-3 parts of pigment. By adopting the micro-injection molding process, the precise heat-conducting anti-static silica gel product can be prepared, the preparation process is simple,environment-friendly and healthy, and the silica gel product can be applied to medical and household appliance parts, has excellent performance, is heat-conducting and anti-static, the quality is greatly improved, and the service life is long, and the heat-conducting anti-static silica gel product can be used for kitchen ware products, medical products, mobile phone cases, automobile interior parts and the like.

Description

technical field [0001] The invention belongs to the technical field of new material modification processing, and in particular relates to a heat-conducting and anti-static silicone product and a micro-injection molding process thereof. Background technique [0002] Liquid Silicone Rubber, referred to as LSR, is a product that is favored by consumers and manufacturers. Liquid Silicone Rubber is made of silicone products. It has good elasticity, waterproof and moisture resistance, and is resistant to acids and alkalis. The erosion of chemical substances, so it is generally used to replace household plastic products. Liquid silicone is injected into the hot runner mold to make silicone products, which can achieve the advantages of one-time molding, no waste and automation. However, existing silica gel products have strong adsorption capacity due to their inherent non-conductive and non-thermal conduction properties. If they are exposed to the air, they will easily absorb dust ...
