Abrasion resistance and impact resistance rubber sealing piece

Abstract

The invention discloses an abrasion resistance and impact resistance rubber sealing piece. The abrasion resistance and impact resistance rubber sealing piece comprises the following raw materials, by weight, of 20-50 parts of ethylene-propylene-diene monomer rubber, 10-20 parts of carboxyl-terminated butyronitrile rubber, 12-35 parts of chloroprene rubber, 1-2 parts of 1,1-double-(tertiary butyl peroxide) cyclohexane, 0.1-0.6 parts of dichromic acid sodium ammonium, 1-2 parts of titanate coupling agent TMC-TTS, 15-25 parts of nylon fibers, 2-6 parts of quartz powder, 10-20 parts of silicon carbide fibers, 2-8 parts of zirconia fibers, 1-2 parts of pine tar oil, 0.2-0.8 part of dioctyl phthalate, 1-2 parts of triethyl phosphate, 0.4-0.8 part of beeswax, 1-2 parts of vaseline and 1-3 parts of anti-aging agents. The abrasion resistance and impact resistance rubber sealing piece is good in toughness, excellent in impact resistance and abrasion resistance performance, good in corrosion resistance and aging-resistant performance, easily available in raw material and low in production cost.

Description

technical field [0001] The invention relates to the technical field of seals, in particular to a wear-resistant and impact-resistant rubber seal. Background technique [0002] Rubber parts for automobiles play a major role in anti-vibration, noise reduction, driving stability and ride comfort of vehicles. The amount of general-purpose rubber materials used in automobiles is relatively large, but as the engine tends to develop in the direction of high power and miniaturization in recent years, the ambient temperature around the engine has increased, and the emission control regulations have become more stringent. In addition, the use of alcohol-containing fuels has forced rubber Parts improve heat resistance, cold resistance, oil resistance, aging resistance and other properties. Therefore, the consumption of high-performance special synthetic rubber continues to increase. Automobiles are the main market for these special synthetic rubbers, especially for high-temperature re...

Problems solved by technology

Therefore, the consumption of high-performance special synthetic rubber continues to increase. Automobiles are the main market for these special synthetic rubbers, especially for high-temperature resistant oil seals, crankshafts, valve stems, cylinder gaskets, hydraulic oil pipes, etc. for automobiles. Existing rubber seals Toughness, impact resistance and wear resistance can not meet the demand and need to be improved urgently
