Cold-resistant rubber and preparation method thereof

Abstract

The invention discloses cold-resistant rubber and a preparation method thereof. The cold-resistant rubber comprises, by weight, 33-35 parts of CPE135B, 6-12 parts of metallic oxide, 0.5-1.5 parts of stearic acid, 1-3 parts of anti-aging agent, 2-4 parts of dispersing agent, 0.1-1.6 parts of paraffin, 70-90 parts of reinforcing agent, 90-100 parts of anti-freezing agent, 4-6 parts of accelerant, 1.0-1.4 parts of vulcanizing agent, 1.5-3.5 parts of hyperoxide, 2-4 parts of 512 ethylene-propylene rubber, 0.2-0.4 part of anti-aging agent RD, and 7-9 parts of JXB05-1 white carbon black. The cold-resistant rubber overcomes the defects in the prior art, is used for manufacturing washers arranged between mechanical muff-coupling parts, has the advantages of being good in elasticity, resistant to aging, resistant to acid and alkali and resistant to mechanical dissolubility, and can be used in the hostile environment.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to cold-resistant rubber and a preparation method thereof. Background technique [0002] Low temperature has a great influence on the physical and mechanical properties of rubber products, mainly in the hardening of rubber products (increased hardness and tensile strength), brittleness, loss of elasticity and other aging phenomena, which reduce the original quality of rubber products. At present, there are a lot of rubber seals in the car. When the car is running in a very low temperature environment, especially in very cold regions such as the Northeast, the elasticity of the rubber seals will decrease in the low temperature environment, and brittle damage will occur, resulting in oil leakage. Gas, etc., directly affect the safe driving of the car. Therefore, it is of great significance to speed up the development of new materials and improve the quality of rubber products in cold ...
