Abstract

The invention relates to application of a bismuth oxychloride/sulphur/potassium titanate compound ingredient to a phenolic-resin-based friction material. The compound ingredient is obtained through pelleting; the content of the compound ingredient in the phenolic-resin-based friction material is 5-40wt%; and the compound ingredient is capable of increasing the stability of the friction coefficient, reducing the wear rate and replacing poisonous and harmful sulfides.

Description

technical field [0001] The invention belongs to the field of friction materials, in particular to a bismuth oxychloride / sulfur / potassium titanate composite material acting on phenolic resin-based friction materials, the bismuth oxychloride / sulfur / potassium titanate composite material can improve the performance of phenolic resin-based friction materials Excellent friction coefficient stability, reduced wear rate, and reduced environmental pollution caused by friction dust. Background technique [0002] With the development of society and science and technology, automobiles are gradually becoming an essential tool in people's lives, and the number of automobiles has increased sharply. The resulting environmental problems have attracted international attention. The air pollution caused by automobiles mainly comes from two aspects: automobile exhaust and friction dust. Friction dust is produced by friction between brake pads and brake discs during the braking process, which co...
