Abstract

The invention discloses an environmental-protection high-speed car brake sheet and a warm-pressing process of the brake sheet. A frictional material of the environmental-protection high-speed car brake sheet comprises the following components in parts by weight: 6-8 parts of phenolic resins, 2 parts of acrylonitrile rubber powder, 1-3 parts of Kevlar fibers, 5-7 parts of stannic sulfide, 5-7 parts of artificial graphite, 2 parts of polytetrafluoroethylene, 18-20 parts of steel fibers, 4-6 parts of red copper fibers, 2 parts of aluminum oxide, 3-5 parts of zirconium silicate, 5-7 parts of iron oxide black, 7-9 parts of titanium white, 6-8 parts of mineral fibers, 7-9 parts of white vermiculite, 8-10 parts of grammite and 5-9 parts of barium sulfate. The warm-pressing process of the environmental-protection high-speed car brake sheet comprises the steps of material burdening, material mixing, warm-pressing formation, thermal treatment, grinding and spraying. The high-speed car brake sheet has the advantages of safe and comfortable brake, no noise, low high-temperature and high-speed recession, stable frictional factor, environmental protection, long service life and the like; and the warm-pressing process of the environmental-protection high-speed car brake sheet has the advantages of high rate of finished products, high mechanical degree, high production efficiency and low energy consumption.

Description

technical field [0001] The invention relates to the technical field of new car brake materials, in particular to an environment-friendly high-speed car brake pad and a temperature-pressing process thereof. Background technique [0002] With the rapid development of social economy, China has entered the era of cars, especially a series of economic policies issued by the government have provided more room for the development of the car market; with the rapid development of the car market, people are paying more and more attention to cars The various performances of the vehicle, especially the braking performance, are directly related to the life safety of the driver and passengers. The car's braking performance is achieved by the car's braking system, which shows the importance of the car's braking system. [0003] The braking system of a car is composed of four major parts: brake oil pump, brake calipers, brake pads, and brake discs. The performance of the brake pads is dire...
