Abstract

The invention discloses low-temperature resistant irradiation fluorosilicone rubber which comprises the following ingredients in parts by weight: 100 parts of methylvinyl phenyl silicone rubber, 20-100 parts of vinyl terminated liquid fluorosilicone rubber, 1-20 parts of methyl phenyl silicone oil, 1-10 parts of silicon-aluminum polymer, 5-30 parts of fumed silica, 5-50 parts of hard clay, 5-30 parts of kieselguhr and 0.5-5 parts of tackifying resin. The low-temperature resistant irradiation fluorosilicone rubber can be effectively applied to sealing positions contacted with fuel oil and lubricating oil in the field of automobiles, machines and the like, and the loss caused by brittle failure of a low-temperature environment to the rubber is reduced.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and in particular relates to a radiation-crosslinked low-temperature-resistant fluorosilicone rubber. Background technique [0002] Fluorosilicone polymer, also known as organic fluorosilicone rubber, is a kind of silicone rubber with the characteristics of high and low temperature resistance, aging resistance and fluororubber heat resistance, weather resistance, waterproof, corrosion resistance, oil resistance, solvent resistance and other advantages. A new type of elastomer material can be widely used in important industrial sectors and fields such as automobiles, aircraft, aerospace, petrochemicals, machinery, and artificial organs. It has become an indispensable new polymer material in national defense and national economy. At present, the fluorosilicone rubber products used in the industry can be used for a long time in the range of -60℃~250℃. However, at ultra-low temperatures, suc...
