Problems solved by technology

[0004] The object of the present invention is to provide the formula and processing technology of the friction lining cloth for automobile clutch, to solve the problem that some ingredients of the existing friction lining cloth for automobile clutch proposed in the above background technology will evaporate and pollute the surrounding working environment. And the cost of the process is high, the friction coefficient is small and the stability is poor, the difference between the dynamic friction coefficient and the static friction coefficient is large, and the strength is low, it cannot bear a large impact, it is easy to break and peel off at high speed, and it is wear-resistant, high-temperature resistant, and resistant to friction. Poor corrosion and thermal conductivity, large thermal deformation, easy to cause adhesion when left standing for a long time, and short service life

Abstract

The invention discloses a seeping cloth formula of a friction plate for an automobile clutch. The seeping cloth formula comprises the following components: cloth for the clutch friction plate, 90-110kg of water, 2-3 kg of polyvinyl alcohol, 50-60 kg of latex, 30-35 kg of resin, 30-35 kg of barite powder, 5-6 kg of carbon black, 1.5-2.5 kg of graphite powder, 6-7 kg of grinding ash, 0.8-1 kg of sulfur, 0.2-0.8 kg of zinc stearate and 0.3-0.6 kg of caustic soda. According to the formula and the processing technology of the friction plate seeping cloth for the automobile clutch, the friction plate seeping cloth is large and stable in friction coefficient, close to a static friction coefficient in dynamic friction coefficient, high in strength, capable of bearing impact, not prone to breakageand stripping at a high speed, resistant to abrasion, high temperature and corrosion, good in heat conduction performance, small in thermal deformation, free of adhesion during long-term standing, long in service life, easy to process and cheap; and the used formula materials do not fall to the ground, do not evaporate, and are environment-friendly.

Description

technical field [0001] The invention relates to the technical field of production of friction lining cloth for automobile clutches, in particular to the formula and processing technology of friction lining cloth for automobile clutches. Background technique [0002] The automobile clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed on the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. During the driving process, the driver can Depress or release the clutch pedal to temporarily separate and gradually engage the engine and gearbox to cut off or transmit the power input from the engine to the transmission, and the friction plate cloth is a kind of cloth specially used for automobile clutches; [0003] However, part of the ingredients of the existing friction plate cloth for automobile clutches will evaporate, pollute the surrounding working environment, the cost of ...
