Abstract

The invention discloses a high-strength tear-resistant methyl vinyl silicone rubber material. The high-strength tear-resistant methyl vinyl silicone rubber material comprises, by weight, 80-100 parts of raw methyl vinyl rubber, 1.5-2.5 parts of Teflon, 1-3 parts of methyl silicone oil and 0.4-0.8 parts of aluminum stearate, and also comprises, based on the raw methyl vinyl rubber, 0.8-1wt% of gamma-aminopropyltriethoxysilane, 1-1.4wt% of N-(beta-aminoethyl)-gamma-aminopropyltriethoxysilane, 3.5-4wt% of nano-cellulose whisker, 12-15wt% of silica micropowder, 0.5-0.9wt% of hydrosilicone oil and 33-48wt% of modified white carbon black. Compared with the original silicone rubber, the high-strength tear-resistant methyl vinyl silicone rubber material improves density and tensile strength, has good flame retardation, excellent wear resistance and tear resistance, and improves silica gel safety.

Description

technical field [0001] The invention relates to the technical field of methyl vinyl silicone rubber, in particular to a high-strength and tear-resistant methyl vinyl silicone rubber material. Background technique [0002] Silicone rubber refers to a type of elastomer whose molecular main chain is Si-O inorganic structure and side chain is organic group. Silicone rubber is a semi-inorganic saturated, heterochain, non-polar elastomer. At present, silicone rubber is widely used in construction, chemical industry, transportation, electronic appliances, biological materials and aerospace materials. It has excellent heat resistance, low temperature resistance, insulation, earthquake resistance, compression resistance, and abrasion resistance. And good biological properties, but silicone rubber has low tensile strength, tear resistance, wear resistance, and poor flame retardancy, which affects the scope and function of silicone rubber. Contents of the invention [0003] The tec...
