Abstract

The invention relates to an organic fiber friction material composition for a brake pad, which is prepared from the following components in parts by weight: 3-7 parts of chromite, 4-8 parts of barite, 5.5-7 parts of calcined petroleum coke, 3-6 parts of flaky graphite, 10-14 parts of boric acid modified phenolic resin, 3-6 parts of meerschaum fiber, 4-7 parts of ceramic fiber, 1.5-3 parts of antimony sulfide, 4-7 parts of bronze powder, 3-5 parts of glass wool, 1-2.5 parts of zirconite, 6-10 parts of flaky potassium titanate, 8-11 parts of vermiculite powder, 1-2.5 parts of carbon fiber, 4-6 parts of aramid fiber pulp, 1-2.5 parts of wood pulp cellulose, 3-6 parts of viscose fiber, 6-9 parts of silicon carbide and 6-10 parts of cellulose fiber. The invention has the advantages of small specific gravity, high wear resistance, favorable toughness, low noise, long service life and the like. The glass wool, bronze powder and other heat dissipation materials added in the formula can effectively perform the functions of heat insulation and heat dissipation.

Description

technical field [0001] The invention relates to an automobile brake pad, in particular to an organic fiber friction material composition for the brake pad. Background technique [0002] Today, with the rapid development of the automobile industry, the safety and environmental protection of vehicles are particularly important, and the new requirements for automobile brake pads are constantly increasing. Automobile brake pads are subjected to external pressure to generate friction during work, so that the vehicle can achieve the purpose of deceleration. Therefore, the wear resistance and heat resistance of the material of the brake pad are very important. The research on brake pads in our country started later than that in foreign countries, and there is still a big gap with the developed countries in the world. Some brake pad manufacturers are still in the traditional era of asbestos brake pads, which no longer meet the requirements of the modern automobile industry. [00...
