Abstract

The invention relates to rubber for an automobile exhaust pipe lifting ring. The rubber is prepared from, by weight, 60-75 parts of ethylene propylene diene monomer, 35-45 parts of chlorosulfonated polyethylene rubber, 1-2 parts of trithiocyanuric acid, 4-7 parts of an anti-aging agent, 7-12 parts of accelerant, 5-10 parts of N-330 carbon black, 5-10 parts of activated zinc oxide, 0.5-1 part of paraffin, 1-3 parts of stearic acid, 1.5-2.5 parts of a vulcanizing agent, 1.5-3.5 parts of plasticizer and 10-15 parts of paraffin oil. The rubber has the advantages that by means of the synergistic effect among all the raw materials, the rubber effectively improves heat resistance of the automobile exhaust pipe lifting ring when used for preparing the automobile exhaust pipe lifting ring; in addition, aging resistance of the automobile exhaust pipe lifting ring is 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 noise reduction function is the exhaust pipe of the car, and a muffler is installed inside it. , greatly reducing 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 of the exhaust pipe during movement and prevent the collision between the exhaust pipe and ...
