Abstract

The invention discloses a kind of none asbestos clutch facing used in cars and its production technology. The recipe of the component is that: E-glass fiber 30~50%, fragrance fiber 1~4%, polyacrylonitrile fiber 0.6~1.2%, the oil of cashew shell friction-type mix 3~6%, oil coke blacking 3~5%, particle graphite 5~8%, zinc oxide 0.2~1%, calcium sulfate 5~15%, heavy calcium carbonate 10~20%, flour acrylonitrile butadiene rubber 15~25%, anti-aging protective TMQ 0.2~0.5%, curing accelerator MBTS 0.2~0.5%, the oil of cashew shell resin modified 6~12%. Banburying mix the component told above in proportions at the proper temperature then make up pellicle by smelting and at last rolls in with the E-glass fiber then forms different ordinance blanks by winding. The blanks confect by heat pressing at the proper temperature and pressure then make into production by grinding and drilling holes. It has the merits like that: high strength, good ductility and stabilize coefficient of friction and so on.

Description

Technical field: [0001] The invention belongs to the technical field of automobile braking systems, and in particular relates to a production formula and a production process of an asbestos-free automobile clutch face. Background technique: [0002] The clutch face is mainly composed of three parts: binder, reinforcing material, and friction filler. The reinforcing material used before the 1990s was mainly asbestos, and asbestos would cause environmental pollution and endanger human health. With the new situation of China's accession to WTO, the rapid development of the automobile industry, the procurement of auto parts has also become a global development trend, the amount of clutch facings is increasing year by year, and higher requirements are put forward for its performance (especially heavy-duty clutch facings) . In order to connect with the international market, the domestic automobile friction material industry has been researching and developing non-asbestos product...
