Green friction-resistant material coating

Abstract

The invention discloses a green friction-resistant material coating which is composed of the following components in parts by weight: 8-16 parts of kieselguhr, 5-9 parts of open-pore expanded perlite, 5 parts of silicon dioxide powder, 1-5 parts of talcum powder, 1-3 parts of titanium white, 20-30 parts of limestone, 0.5-2.0 parts of defoamer, 0.5-1.5 parts of modified acrylic emulsion, 1 part of thickener and 100 parts of water. The friction material disclosed by the invention is free of no substances harmful to the human body, and has the advantages of no braking noise, low wear rate, stable high-temperature braking performance, smooth slowdown braking and low cost.

Description

technical field [0001] The invention relates to a green friction-resistant material coating. Background technique [0002] At present, there are three types of friction materials used in domestic vehicles: 1) Asbestos-based: Its manufacturing cost is low and the process is simple, and it is mainly used for agricultural vehicles and construction machinery. Its disadvantages: asbestos is harmful to the human body, pollutes the environment, suffers from severe high-temperature heat decay, poor braking performance, and low safety factor. This kind of product has been decreasing year by year. 2) Semi-metal base: It has good temperature resistance and decay resistance at high temperature, and its manufacturing quality is moderate. Its disadvantages are: high hardness of the product, noise during braking, especially when braking at low speed or in the morning. It is easy to produce noise, the surface of the product is easy to rust, and at the same time corrodes the counterpart, th...

Problems solved by technology

Its disadvantages: asbestos is harmful to the human body, pollutes the environment, suffers from severe heat decay at high temperature, poor braking performance, and small safety factor. This kind of product has been decreasing year by year.

2) Semi-metal base: It has good temperature resistance and decay resistance at high temperature, and its manufacturing quality is moderate. Its disadvantages are: high hardness of the product, noise during braking, especially when braking at low speed or in the morning. It is easy to generate noise, the surface of the product is easy to rust, and at the same time corrodes the counterpart, the thermal conductivity is high, and when the friction temperature is higher than 300 degrees, it is easy to decompose the adhesive between the friction material and the steel sheet

3) Less metal base: the advantage is that it is less aggressive to the drum, and the noise is low. The disadvantages: the problem of noise and ash falling has not been solved, and it is easy to rust
