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

Abstract
The invention discloses an environment-friendly biological friction material, which is composed of the following components in parts by weight: 9 to 10 parts of diatomaceous earth, 25 to 30 parts of pore-open expanded perlite, 3 to 9 parts of wood fiber, 1 to 2 parts of sarcandra glabra, 3 to 6 parts of ash bark, 55 to 60 parts of PP, 45 to 50 parts of PE, 35 to 40 parts of rubber powder, 2 to 3 parts of a fire retardant, 9 to 15 parts of mica powder, 16 to 24 parts of ceramic powder, 1 to 2 parts of anatase type titanium dioxide powder and 5 to 20 parts of an inorganic thickening agent. According to the environment-friendly biological friction material, plant Chinese herbal medicinal ingredients are added into the material, substances harmful to people's health are not contained, brake noise is avoided, the wear rate is low, the high temperature brake performance is stable, the deceleration braking is smooth and steady, and the cost is low.
Description
technical field [0001] The invention relates to an environment-friendly friction material. 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, the ...
