Abstract

The invention discloses a kind of disk brake staff facing used in cars with none asbestos and little metal and the production technology. Its friction material includes bed charge and plus material. The bed charge includes: mineral fiber 35~50%, barite powder 10~20%, heavy calcium carbonate 10-20%, the oil of cashew shell phenol-formaldehyde resin modified 20~30%, flour acrylonitrile butadiene rubber 2~15%. The match of plus material: kaflar fiber 0.1~3%, steel fiber 20~35%, copper fiber 1~5%, particle graphite 6~18%, oil coke blacking 5~15%, the oil of cashew shell friction-type mix 2~8%, sericite in powder 5~10%, antimony trisulfide 0.5~5%, heavy calcium carbonate 2-8%, barite powder 10~20%, flour acrylonitrile butadiene rubber 2~6%, the oil of cashew shell phenol-formaldehyde resin modified 6~15%. After made the bed charge and the plus material weight them in proportion then chill-pressing confectioning and heat pressing confectioning steps and so on and then rivet accessory at last treatment make up the products. It needs low abrasion and has no noise.

Description

Technical field: [0001] The invention belongs to the technical field of automobile brake systems, and in particular relates to a production formula and a production process of a disc brake lining for automobiles. Background technique: [0002] Brake lining is one of the essential accessories of automobiles and other motor vehicles, and it is related to personal safety. It is mainly composed of three parts: binder, reinforcing material, and friction filler. The reinforcing material used before the 1990s was mainly asbestos, and asbestos would cause environmental pollution and endanger human health. With the new situation of China's entry into WTO and the rapid development of the automobile industry, the procurement of auto parts has also become a global development trend. The amount of brake linings is increasing year by year, and higher requirements are put forward for its performance. In order to be in line with the international market, the domestic automotive friction ma...
