Abstract

A wear-resistant automotive brake pad is characterized by comprising, by weight, 5 to 10 parts of copper powder,4 to 8 parts of calcined coke, 3 to 6 parts of graphite, 7 to 16 parts of absolute ethyl alcohol, 3 to 7 parts of wetting agent, 6 to 12 parts of aluminum silicate fiber, 2 to 7 parts of potassium titanate whisker, 6 to 10 parts of butadiene-acrylonitrile rubber, 3 to 9 parts of boron phenolic resin, 6 to 10 parts of calcium sulfate whisker, 5 to 8 parts of heavy calcium carbonate, 10 to 16 parts of glass fiber, 4 to 8 parts of molybdenum disulfide, 1 to 2 parts of talcum powder, 8 to 16 parts of melamine resin, and 4 to 7 parts of barium sulfide. The wear-resistant automotive brake pad is excellent in wear resistance, noise free and longer in service life.

Description

technical field [0001] The invention relates to a wear-resistant automobile brake pad. Background technique [0002] Brake pads are the most critical safety parts in a car's braking system. Because the braking effect is good or bad, the brake pads play a decisive role, so it is said that a good brake pad is the protector of people and cars. Brake pads are consumables that will gradually wear out during use. When worn to the limit, they must be replaced, otherwise the braking effect will be reduced and even cause safety accidents. Brake pads are related to life safety and must be treated with caution. The wear resistance of brake pads is very critical to brake pads. However, the comprehensive performance of existing friction materials on the market is not very satisfactory, and it is difficult to meet the increasing safety, efficiency and environmental protection requirements. need. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the probl...
