Abstract

The invention discloses a preparation method for rubber for an automobile exhaust pipe lifting ring and belongs to the technical field of rubber pipe products for an automobile. The preparation method comprises the following steps: EPDM and chlorosulfonated polyethylene rubber are put into an internal mixer for plastication, intermediate super carbon black N200, general furnace black N660, indirect zinc oxide, 2-thiol group benzimidazole, 2,2'-dithio-dibenzo thiazole, paraffin oil and strong magnesium powder are added, and mixing is performed to obtain a mixed material; the mixed material is put into vulcanization equipment, zinc diethyl dithiocarbamaate, zinc stearate, trithiocyanuric acid and sulphur are added, vulcanization is performed sequentially at four temperature intervals. Compared with the preparation method for rubber for the automobile exhaust pipe lifting ring in the prior art, the preparation method disclosed by the invention has the advantage that by using the synergistic effect of all raw materials, the heat resistance of the automobile exhaust pipe lifting ring is improved effectively and meanwhile the ageing resistance of the automobile exhaust pipe lifting ring is also improved when the raw materials are used for preparing the automobile exhaust pipe lifting ring.

Description

technical field [0001] The invention relates to the technical field of rubber hose products for automobiles, in particular to a method for preparing rubber 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 c...
