Abstract

Cold resistant rubber for vehicles comprises, by weight, 80-90 parts of natural rubber, 15-30 parts of butadiene styrene rubber, 35-45 parts of butadiene rubber, 8-15 parts of epichlorohydrin rubber, 10-15 parts of crude fluororubber, 20-25 parts of fluorinated silicone rubber, 3-5 parts of aromatic oil, 1-3 parts of stearic acid, 2-4 parts of coupling agent, 5-8 parts of bulking agent, 1-3 parts of acetone, 2-5 parts of methyl ethyl ketone, 3-5 parts of ethyl acetate, 1-2 parts of methylisobutylketone, 2-4 parts of methyl acetate, 20-40 parts of thermal cracking carbon black, 3-6 parts of active magnesium oxide, 3-9 parts of calcium hydroxide, 1-6 parts of cerium oxide, 0.1-0.8 part of processing agent and 0.1-0.8 part of internal releasing agent. The obtained cold resistant rubber has the advantages of low cost, short production cycle, high yield and long service life.

Description

technical field [0001] The invention relates to the field of low-temperature-resistant rubber production, in particular to a novel high-efficiency low-temperature-resistant rubber for vehicles and a production method. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable for people’s daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machinery, electronics and other heavy industries and emerging industries. It can be seen that the rubber industry has a wide variety of products, and the backward industry is very broad. [0003] In the prior art, natural rubber is usually used to manufacture rubber for automobiles. Due to the chemical structure of natural rubber itself, its oxidation resistance and corrosion resistance are poor, thereby affecting the...
