High-quality rubber material for bushes of stabilizer bars

Abstract

The invention provides a high-quality rubber material for bushes of stabilizer bars. The high-quality rubber material comprises, by weight, 80-90 parts of natural rubber, 10-20 parts of tetrapropyl fluoro elastomer, 5-10 parts of chlorosulfonated polyethylene rubber, 35-50 parts of polyacrylate rubber, 3-5 parts of butadiene styrene rubber, 3-5 parts of fluorinated silicone rubber, 40-45 parts of hydrogenated nitrile butadiene rubber, 15-20 parts of N-cyclohexylthiophthalimide, 10-20 parts of epoxy propane rubber, 5-10 parts of copolymerization chlorohydrine rubber, 5-10 parts of ethylene-vinyl acetate rubber, 3-5 parts of aromatic hydrocarbon oil, 3-5 parts of polyether-ether-ketone, 5-10 parts of carbon black, 5-6 parts of nanometer tin dioxide, 3-5 parts of calcined pottery clay, 3-5 parts of dicumyl peroxide, 4-5 parts of zinc oxide, 3-4 parts of magnesium oxide, 1-5 parts of polyamide wax micro-powder, 3-8 parts of magnesium stearate, 5-10 parts of polyisobutylene rubber, 4-5 parts of titanium dioxide powder and 3-5 parts of naphthenic oil. The high-quality rubber material has the advantages that the high-quality rubber material is excellent in resilience, heat resistance and cold resistance, rubber is good in abrasion resistance, heat aging resistance and dynamic fatigue resistance, and accordingly service requirements of the bushes of the stabilizer bars can be met.

Description

technical field [0001] The invention relates to the technical field of rubber production, in particular to a rubber material for high-quality stabilizer bar bushings. Background technique [0002] The stabilizer bar is an auxiliary elastic component in the car suspension. Its function is to prevent the body from excessive lateral roll when turning, and to keep the body as balanced as possible. The stabilizer bar bushing is fixed on the frame through a hoop, which supports and positions the stabilizer bar. At the same time, the stabilizer bar bushing must have sufficient axial stiffness to limit the axial play of the stabilizer bar. The rubber material of the stabilizer bar bushing must meet the characteristics of good wear resistance, good resilience, and small compression set. The stabilizer bar bushing manufactured in the prior art will produce abnormal noise between the stabilizer bar and the vehicle during driving, especially under low temperature conditions due to the...

AI Technical Summary

Problems solved by technology

The stabilizer bar bushing manufactured in the prior art will produce abnormal noise between the stabilizer bar and the vehicle during driving, especially under low temperature conditions due to the hardening of the rubber of the stabilizer bar bushing, resulting in a greater abnormal sound and resulting in a stable Wear of the rod bushing, reducing service life
