Embodiment Construction

[0013] Friction material production technology is a comprehensive technology integrating experimentation and marginality. It is constantly improved and updated with the development of chemical industry and material technology; in order to adapt to the high-speed development trend of the international automobile industry, the development of brake friction materials The trend can be foreseen: use less metal or no metal as the skeleton material, and at the same time, the material is also required to have the characteristics of high temperature resistance, high strength, small thermal conductivity, small specific gravity, and no noise. Among them, formula technology is the core key of friction material production technology.

[0014] At present, scholars in this field at home and abroad mostly focus on ceramic-based materials. It is under the background of this research at home and abroad that the inventors put forward the composition of the friction material of the present inventi...

Abstract

The invention discloses a low-abrasion environment-friendly composite ceramic-based friction material which comprises the following components in percentage by weight: 5 to 7 phenolic resin, 5 to 9 nitrile rubber, 2 to 5 aramid fiber, 2 to 6 silicon carbide, 15 to 20 ceramic fiber, 3 to 5 zirconia, 8 to 10 artificial graphite, 3 to 10 molybdenum disulphide, 5 to 15 zirconium silicate, 1 to 3 aluminum oxide, 8 to 10 potassium titanate whiskers, 5 to 15 precipitated barium sulfate, 1 to 3 magnesium oxide, 1 to 3 petroleum coke, 3 to 5 friction powder, 8 to 10 vermiculite and 4 to 9 boron nitride. The invention has the advantages that the friction material manufactured by using the components and the blending ratio has the advantages of no asbestos and brake noise, low wear rate, stable high-temperature brake performance, stable speed reduction brake, lower cost than the similar imported products, and the like.

Description

technical field [0001] The invention relates to a friction material, in particular to a low-wear and environment-friendly composite ceramic-based friction material. Background technique [0002] At present, the types of friction materials used in domestic vehicles can be divided into three types: [0003] 1) Asbestos-based: Its manufacturing cost is low and the process is simple; it is mainly used for agricultural vehicles and construction machinery. [0004] Its disadvantages: asbestos is harmful to the human body, pollutes the environment, suffers from severe heat decay at high temperature, poor braking performance, and low safety factor. This kind of product has been decreasing year by year and is an obsolete product. [0005] 2) Semi-metal base: It has good temperature resistance and decay resistance at high temperature, and the manufacturing cost is moderate; it is widely used in China. [0006] Its disadvantages: high hardness of the product, noise during braking, es...
