Novel high-strength silicone rubber fireproof anticorrosive sealing material

Abstract

The invention discloses a novel high-strength silicone rubber fireproof anticorrosive sealing material. The novel high-strength silicone rubber fireproof anticorrosive sealing material comprises following ingredients: vinylsilane rubber, polyvinylsilicone oil, copper fiber, aluminium hydroxide, thermoplastic polychloro ester, Calcium Stearate, EVA resin, poly glycolic acid, agar, sodium laurylsulfate, polyethylidene carbonic carbonate, dioctyl phthalate, a mold lubricant aid, an adhesion, a reinforcing filling agent, a vulcanizing agent, a heat resistant filling material, and an anticorrosivefilling material. In the prior art, added polyvinylsilicone oil is easily induced by peroxide so as to cause integrated crosslinking or one site multi-crosslinking nonuniform sulfuration; high crosslinking degree sites are formed by polyvinylsilicone oil; in tearing, the resistance at the high crosslinking degree sites is large, and tearing is difficult to realize, so that the tearing strength ofsilicone rubber is increased greatly; and in addition, adding of the other ingredients is capable of improving the whole fire resistance, corrosion resistance, and sealing performance, and satisfyingusing requirements of people.

Description

technical field [0001] The invention relates to the technical field of fireproof and anticorrosion sealing materials, in particular to a novel high-strength silicone rubber fireproof and anticorrosion sealing material. Background technique [0002] Due to the special structure of silicone rubber, it has excellent high temperature resistance and low temperature resistance, excellent electrical insulation and chemical stability, good aging resistance, protruding surface activity, hydrophobic moisture resistance and physiological inertia, etc. , is widely used, but most of the current rubbers have poor tensile properties and general physical properties, so they cannot meet people's needs. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a new type of high-strength silicone rubber fireproof and anticorrosion sealing material, which improves the tensile performance of silicone rubber, and has good...
