Abstract

The invention discloses an environment-friendly seal ring material used for a respirator. The environment-friendly seal ring material is prepared from, by weight, 120-140 parts of methyl vinyl phenyl siloxane rubber, 1-2 parts of anti-aging agent MB, 1-2 parts of zinc oxide, 0.9-1 part of sulfur, 4-5 parts of lauryl mercaptan, 1-2 parts of hydroxy zinc stannate, 10-14 parts of dibutyl maleate, 0.8-1 part of dimethyl diallyl ammonia chloride, 0.5-1 part of casein, 6-7 parts of powdered bark, 1-2 parts of triethanolamine, 3-4 parts of calcium palmitate, 2-4 parts of polyacrylamide, 4-5 parts of polyethylene wax, 1-2 parts of sodium laurylsulfate, 3-4 parts of carbon fiber, 0.4-1 part of trimethylolpropane, 5-7 parts of maleic anhydride, 1-2 parts of anti-ageing agent AW, 0.1-0.2 part of potassium peroxodisulfate and 16-20 parts of kieselguhr. The rubber material is high in elongation at break and tensile strength, high in tenacity and water resistance, high in acid and alkali corrosion, high in storage stability and ageing resistance, free of poisonous and harmful substance volatilization, high in environment-friendly performance and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of sealing ring materials, in particular to an environment-friendly sealing ring material for a respirator and a preparation method thereof. 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...
