Abstract

The invention relates to preparation of brake pads in the field of the automobile industry, in particular to a carbon-ceramic based brake pad, which is higher in strength and more stable in performance. In weight percent, the brake pad comprises 5-15% of adhesives, 20-30% of reinforcing materials, 20-30% of frictional property conditioning agents and 30-50% of packing in formula, wherein the adhesives include phenolic resin, silicone modified phenolic resin and butyronitrile modified phenolic resin, the reinforcing materials include carbon fibers, ceramic fibers and aramid pulp, the frictional property conditioning agents include grinding agents and lubricating agents, the grinding agents include aluminum oxide, ferric oxide, magnesium oxide and frictional powder, the lubricating agents include graphite, sulfide and mica, and the packing comprises barium sulfate, potassium titanate and magnesium oxide. The carbon-ceramic based brake pad has negative temperature coefficient, stable chemical performance and resistance to strong acid and strong alkali, and is nonhazardous and extremely high in mechanical performance.

Description

technical field [0001] The invention relates to the preparation of brake pads in the field of automobile industry, in particular to a carbon ceramic base brake pad. Background technique [0002] The processing technology of brake pads is as follows: material mixing, hot pressing, grinding, painting, mounting accessories, printing and packaging. High-temperature degradation and high-speed stability are two crucial performance requirements for brake pads, which directly affect braking safety and comfort. Although the thermal ablation process can improve the recession to a certain extent, it cannot solve this problem, and the ablation is easy to cause other problems, such as: shear force drop, easy to peel off; ablation uniformity; and Product consistency, etc. Contents of the invention [0003] The purpose of the present invention is to change the internal structure of the brake pad and improve the strength of the brake pad by adding reinforcing fibers such as carbon fiber...
