Special brake pad for environment-friendly passenger car

Abstract

The invention discloses a special brake pad for an environment-friendly passenger car. The special brake pad is characterized by being prepared from the following components in parts by weight: 10-12 parts of phenolic resin, 3-5 parts of epoxy resin, 3-5 parts of mineral fibers, 5-10 parts of tin sulfide, 5-7 parts of synthetic graphite, 2 parts of polytetrafluoroethylene, 18-20 parts of steel fibers, 4-6 parts of red copper fibers, 2 parts of alumina, 3-5 parts of frictional powder, 5-7 parts of carbon black, 7-9 parts of titanium dioxide, 5-10 parts of mineral fibers, 8-10 parts of wollastonite and 5-10 parts of calcium sulfate. The special brake pad for the environment-friendly passenger car has the characteristics that the high-speed high-temperature recession is low; the speed sensitivity is especially low; friction coefficients are very stable when the passenger car is braked from the low speed of 40km per hour to the high speed of 180km per hour; an average friction coefficient is 0.30 micrometers; and a good result can be realized when the high-speed friction coefficient of the passenger car braking is 0.30 micrometers, so that a braking distance of the passenger car during the high-speed movement is reduced and a safety coefficient of the passenger car can be improved.

Description

technical field [0001] The invention relates to the technical field of new car brake materials, in particular to an environment-friendly special brake pad for cars. 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. The most important safety system on a car is the braking system, and all braking components are safety components. Brake pads are one of the most important links in the entire braking system, which will directly ...
