Abstract

Provided is a high-performance friction material composition containing grapheme. The composition is characterized in that the composition is made of amino silane, calcium silicate hydrate, polyacrylonitrile fibers, electric-melting zirconia, aramid fibers, hemp fibers, expanded vermiculite, ceramic fibers, magnetite, and graphene based on weight ratio. The composition is characterized by green and environmentally-friendly, good high-temperature resistance and heat fading resistance, good wear-resisting property, stable friction coefficient, and long service life. Through rational matching of various kinds of components, advantages of each material are fully developed in the friction material. The recipe does not have heavy metal substances, and the composition is very friendly to environment.

Description

technical field [0001] The invention relates to a friction material composition for an automobile brake pad, in particular to a high-performance friction material composition containing graphene. Background technique [0002] With the rapid development of the automobile industry, vehicle safety and environmental protection are particularly important. People are increasingly concerned about the environmental performance of brake pads. At present, many new high-performance brake pads have appeared on the market, but while improving the braking performance , It has a huge impact on the living environment, and the brake noise and harmful gas emissions cannot be effectively controlled. The friction materials used in the automobile brake pads we use now contain many heavy metal substances, including antimony, chromium, cadmium, copper, barium, copper and other heavy metals. Every time a car brakes, a small amount of heavy metal dust is released and accumulated in the environment,...
