Abstract

The invention provides a wet-processing brake gasket. The wet-processing brake gasket is characterized by comprising, by mass, 15-17% of resin, 6-12% of fibers, 10-20% of water residues, 15-25% of bentonite, 2-7% of antifriction agent, 15-30% of fillers and 15-25% of hot water. Friction materials produced by the wet-processing brake gasket are long and thin in friction performance and stable in friction coefficient, product friction can be lowered, production environment can be improved, and dust pollution can be reduced.

Description

technical field [0001] The invention is a non-asbestos NAO type automobile brake lining suitable for automobiles, especially for trucks and passenger vehicles, which is "asbestos-free, glass-fiber-free and metal-free". Background technique [0002] At present, traditional automobiles, especially the manufacturing methods of non-asbestos brake friction materials for automobiles, use phenolic resin or generally modified phenolic resin as binder, various reinforcing fibers as skeleton materials, and various Functional fillers, such as friction-increasing fillers, wear-resistant fillers and cost-reducing fillers, are used as fillers. After a series of processes such as mixing, molding, hot pressing, heat treatment and grinding, it is finally made into a brake lining for automobiles, especially non-asbestos automobiles. This traditional process method, that is, the dry production process, mainly has a relatively serious dust problem, which causes dust damage to the environment. ...
