Abstract

The invention discloses an environment-friendly sealing ring which is composed of the following raw materials in parts by weight: 120-140 parts of methylvinylphenylsiloxane rubber, 1-2 parts of an anti-aging agent MB, 1-2 parts of magnesium oxide, 0.9-1 part of sulfur, 4-5 parts of lauryl mercaptan, 1-2 parts of zinc hydroxystannate, 10-14 parts of dibutyl maleate, 0.8-1 part of dimethyl diallyl ammonium chloride, 0.5-1 part of carboxymethyl cellulose, 6-7 parts of bark powder, 1-2 parts of triethanolamine, 3-4 parts of calcium palmitate, 2-4 parts of saturated stearamide, 4-5 parts of polyethylene wax, 1-2 parts of sodium laurylsulfate, 3-4 parts of carbon fibers, 0.4-1 part of trimethylolpropane, 5-7 parts of maleic anhydride, 1-2 parts of an anti-aging agent AW, 0.1-0.2 part of potassium peroxodisulfate, and 16-20 parts of diatomite. The environment-friendly sealing ring has the advantages that the rubber material has the advantages of high elongation at break, high tensile strength, good toughness, strong water resistance, strong acid and alkali resistance, good storage stability, strong anti-aging property, no volatilization of toxic or harmful substances, good environmental protection and superior comprehensive performance.

Description

technical field [0001] The invention relates to a sealing ring, in particular to an environment-friendly sealing ring. Background technique [0002] The remarkable feature of silicone rubber is high temperature stability. Although the strength of silicone rubber at room temperature is only half that of natural rubber or some synthetic rubber, it can still maintain a certain degree of flexibility and resilience in high temperature environments above 200°C. Elasticity and surface hardness, and no significant change in mechanical properties. Low temperature performance The glass transition temperature of silicone rubber is generally -70~-50°C, and the special formula can reach -100°C, which shows that it has excellent low temperature performance. This is of great significance to the aviation and aerospace industries. The Si-O-Si bond in weather-resistant silicone rubber is very stable to oxygen, ozone and ultraviolet rays, and it has excellent weather resistance without addin...
