Abstract

The invention discloses a production technology of a rubber material for producing a friction plate of an automobile clutch. Natural rubber, nitrile rubber, oil-extended styrene-butadiene rubber, zincoxide, stearic acid, microcrystalline wax, an accelerator, an antiager, tackifying resin, carbon black, wollastonite, a rubber activator, sulfur, a rubber softener, a rubber plasticizer and a preservative are used as raw materials, specific weights of all the components are strictly controlled and a traditional rubber material formula is changed; the rubber activator is added in the raw materialsfor improving the performance of the formed rubber material; the preservative is dehydroacetic acid, is degraded into acetic acid in an aqueous solution and has no toxicity to a human body; by avoiding a vulcanization technology, the pollution to the environment is prevented; the preservative is the dehydroacetic acid and has no toxicity to the human body; the nitrile rubber replaces butadiene styrene rubber in an existing formula, so that high temperature resistance of the rubber material is greatly improved; by adopting a water bath heating mode, water temperature is easily controlled, theprepared temperature environment is ensured and the performance of the rubber material is more stable.

Description

technical field [0001] The invention relates to the technical field of clutches, in particular to a production process for rubber materials used in the production of automobile clutch friction plates. Background technique [0002] The friction plate of the clutch is made of asbestos, metal wire and other materials. With the increasing power, speed and load of the car, the operating conditions are increasingly harsh, and higher requirements are put forward for the performance of the friction plate; when working for a long time or Under extreme working conditions, faults such as surface fracture, slippage, ablation and plastic deformation of the friction plate caused by abnormal friction are prone to occur. Studies have shown that rubber materials have an important impact on the performance of the clutch and even the entire vehicle. [0003] The traditional rubber material is easy to cause secondary pollution during the preparation process, and the high temperature resistance ...
