Abstract

The invention discloses a cold-resistant rubber seal ring. The cold-resistant rubber seal ring is prepared from the following raw materials in parts by weight: 30-50 parts of ethylene propylene diene monomer, 50-80 parts of butadiene rubber, 2-3.5 parts of zinc stearate, 3-5 parts of diphenyl silandiol, 1-3 parts of dioctyl phthalate, 2.6-3.5 parts of microcrystalline wax, 6-8 parts of high wear-resistant carbon black, 10-15 parts of magnesium oxide, 12-15 parts of modified silica powder, 4-6 parts of rutile type titanium dioxide, 3-6 parts of alum powder, 5-8 parts of nanometer calcium carbonate, 5-8 parts of naphthenic rubber oil, 1-2 parts of sodium pyrophosphate, 2-3 parts of antiager, 3-5 parts of accelerant PZ, 0.15-0.3 part of sodium lignin sulfonate, 5-7 parts of solid coumarone, 1.2-1.4 parts of turpentine oil, 20-30 parts of cold-resistant agent and 2-2.5 parts of sulfur. The cold-resistant rubber seal ring disclosed by the invention has very good cold resistance and does not crack at a low temperature; in subzero 30 DEG C environments, the cold-resistant rubber seal ring does not become brittle, and the good performances of the cold-resistant rubber seal ring are maintained.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a cold-resistant rubber sealing ring. Background technique [0002] Rubber sealing rings are used in all walks of life, and are generally used for sealing between mechanical parts. The low temperature environment has a great influence on the physical and mechanical properties of rubber products, mainly manifested in the hardening, brittleness, loss of elasticity and other aging phenomena of rubber products, which reduce the original quality and service life of rubber products. At present, a large number of rubber sealing rings are used in automobiles. When the car is driving in a very low temperature environment, especially in very cold regions such as the Northeast, the elasticity of the rubber sealing rings decreases in low temperature environments, and brittle damage occurs, resulting in air leakage. Oil leakage, etc., directly affect the safe driving of the car. Contents of...
