Abstract

The invention discloses a stabilizer bar bush. The stabilizer bar bush comprises the following raw materials in parts by weight: 60 to 100 parts of natural rubber, 0 to 40 parts of butadiene rubber, 30 to 80 parts of carbon black, 1 to 3 parts of a 2,2,4-trimethyl-1,2-dihydroquinoline polymer, 1 to 3 parts of N-isopropyl-N'-phenyl-p-phenylene diamine, 0.1 to 0.5 part of N-cyclohexylthiophthalimide, 1 to 3 parts of insoluble sulfur, 0.5 to 3 parts of N-cyclohexyl-2-benzothiazole sulfenamide, 1 to 3 parts of stearic acid, 1 to 3 parts of a lubricant WB212, 1 to 3 parts of AFLUX25, 1 to 3 parts of rubber microcrystalline wax, 0 to 10 parts of erucamide and 0 to 10 parts of aromatic oil. The invention also discloses a preparation method for the above-mentioned stabilizer bar bush. The stabilizer bar bush provided by the invention has the advantages of good durability, high strength, high elongation, aging resistance and good low temperature performance.

Description

technical field [0001] The invention relates to the technical field of stabilizer bar bushings, in particular to a stabilizer bar bushing and a preparation method thereof. Background technique [0002] Today, with the rapid development of the automobile industry, higher requirements are put forward for the comfort of the car when driving. Because the car body tilts seriously when the car is turning or the road surface is uneven, the handling performance is poor, and the driver feels uncomfortable when driving. The stabilizer bushing rubber products assembled on the horizontal stabilizer bar of the automobile suspension can play the roles of positioning, support, cushioning, shock absorption and noise reduction, so as to improve the handling, comfort and stability of the car. However, with the extension of time, permanent deformation and aging phenomena of rubber parts will inevitably occur, such as heat aging, ozone aging and fatigue aging deformation after long-term use, so...
