Abstract

The invention discloses a high-temperature resisting anti-cracking clutch facing. The high-temperature resisting anti-cracking clutch facing is prepared from the following raw materials in parts by weight: 2 to 4 parts of styrene-butadiene rubber, 0.3 to 0.6 part of modified bamboo fibers, 0.3 to 0.6 part of ceramic fibers, 5 to 7 parts of strengthened material, 1 to 2 parts of single-layer graphene, 5 to 7 parts of nano-silica, 1 to 3 parts of nano titanium dioxide, 4 to 6 parts of zinc stearate, 0.5 to 1 part of sulfur and 15 to 18 parts of phenolic resin. The high-temperature resisting anti-cracking clutch facing has the advantages of high strength, good toughness, stable friction coefficient, good anti-jitter performance, high rotating burst strength, stable friction performance at high temperature and low possibility of producing degradation phenomenon; in addition, the high-temperature resisting anti-cracking clutch facing is an environment-friendly product. According to a preparation technology of the high-temperature resisting anti-cracking clutch facing disclosed by the invention, the preparation technology targeted for specific components is optimized, so that the fusionand the crosslinking of the components are more sufficient; in addition, the preparation process is green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of automobile transmission systems, in particular to a high-temperature-resistant and crack-resistant clutch face and a preparation process thereof. Background technique [0002] The clutch face is a polymer ternary composite material, which is mainly composed of polymer binder (resin and rubber), reinforcing material, friction filler and other compounding ingredients. It is produced through a series of production and processing. products. Due to the vigorous development of the automobile industry, its requirements for the transmission system are also more stringent, and the friction material must comply with the demand. On the one hand, it must meet the various performance indicators that should be achieved during the transmission of the automobile. On the other hand, it must meet the safety, comfort and stability of use. , Harmless to the human body, no pollution to the environment, and also have the effe...
