Abstract

The invention discloses an anti-radiation silicone rubber sealing gasket and a preparation method thereof.The anti-radiation silicone rubber sealing gasket is prepared from, by weight, 29-38 parts of methyl vinyl trifluoropropyl silicone rubber, 21-32 parts of hydrogenated butadiene-acrylonitrile rubber, 20-30 parts of ceramic polishing waste, 4-6 parts of polyamino bismaleimide, 2.5-4 parts of 2,4-dichlorobenzoyl peroxide, 1-2 parts of cadmium stearate, 3-5 parts of polyethylene wax, 5-7 parts of antimony pentasulfide, 4-6 parts of ethyleneglycol dimethacrylate, 15-20 parts of nano barium sulfate, 12-14 parts of polyneopentylene-hexamethylene adipate glycol, 6-12 parts of terpene-styrene resin, 2-3 parts of promoter TBBS, 1.5-2.5 parts of anti-aging agent BLE and 8-12 parts of modifier.The anti-radiation silicone rubber sealing gasket has the excellent anti-radiation property and good high and low temperature resistance, oil resistance, solvent resistance, chemical resistance and ozone aging resistance.

Description

technical field [0001] The invention relates to a rubber gasket, in particular to a radiation-resistant silicone rubber gasket and a preparation method thereof. Background technique [0002] Silicone rubber has outstanding high and low temperature resistance, maintains good elasticity in the temperature range of -70°C to +260°C, is resistant to ozone, weathering and aging, and has excellent properties such as waterproof, flame retardant, high temperature resistance, electrical conductivity, and oil resistance. Performance, suitable for making sealing gaskets required in thermal mechanisms, such as sealing gaskets, valve pads, oil seals (suitable for water media), etc. Special silicone rubber can be used to make oil seals. With the rapid development of science and technology and industry, the performance requirements of silicone rubber sealing materials are getting higher and higher. The existing silicone rubber gaskets on the market have the disadvantage of poor radiation re...
