Abstract

The invention discloses rubber for lifting rings for automobile exhaust pipes, which belongs to the technical field of rubber pipe products for automobiles. The rubber disclosed by the invention is prepared from ethylene-propylene-diene-terpolymer rubber, chlorosulfonated polyethylene rubber, intermediate super carbon black N200, general furnace black N660, indirect zinc oxide, tetramethyl thiuram disulfide, tetraethylthiuram disulfide, 2-mercaptobenzimidazole, zinc stearate, 2,2'-Dithio-dibenzo thiazole, a trithiocyanuric acid, paraffin oil, magnesium powder, and sulphur as raw materials in parts by weight. Compared with rubber for lifting rings for automobile exhaust pipes manufactured in the prior art, when the rubber disclosed by the invention is used for preparing lifting rings for automobile exhaust pipes by using the mutual synergistic effect of the raw materials, the heat resistance of the lifting rings for automobile exhaust pipes is effectively improved, and the aging resistance of the lifting rings for automobile exhaust pipes is also promoted.

Description

technical field [0001] The invention relates to the technical field of rubber hose products for automobiles, in particular to a rubber used for suspension rings of automobile exhaust pipes. Background technique [0002] In terms of the role of the automobile exhaust pipe on the automobile body, it plays the role of shock absorption and noise reduction, and prolongs the life of the exhaust muffler system. The main material of the exhaust pipe is stainless steel. For ordinary cars, because the exhaust gas of the car is under great pressure when it leaves the engine, the noise it produces may make people feel crazy. At this time, the main role of noise reduction is the exhaust pipe of the car. The device greatly reduces the noise of the car. The main function of the automobile exhaust pipe suspension ring is to fix the exhaust pipe to reduce the vibration generated by the exhaust pipe during movement and prevent the collision between the exhaust pipe and the chassis of the ca...
