Abstract

The invention discloses an environmentally friendly high performance grinding material composition. The composition comprises fused magnesia, fused zirconia, aramid fibers, tyre powder, expanded vermiculite, ceramic fibers, magnetite, multiwalled carbon nanotubes, boron-containing phenolic resin and benzoxazine resin. The composition has the characteristics of environmental friendliness, high temperature heat fading resistance, wear resistance, stable friction coefficient and long service life. Through reasonable matching of a plurality of components, advantages of various materials are fully performed in the friction material. The composition does not contain heavy metal substances and is environmentally friendly.

Description

technical field [0001] The invention relates to a friction material composition of an automobile brake pad, in particular to an environment-friendly high-performance friction material composition. 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...
