Abstract

The invention discloses a synthesizing type friction material which is prepared from the following raw materials in parts by weight: 20-40 parts of inorganic bond, 10-20 parts of organic bond, 20-30 parts of bastose, 5-10 parts of coke and 5-15 parts of metal powder. The synthesizing type friction material has high mechanical strength, favorable friction property and heat resistance, can be used for stabilizing and reducing the shrinkage and expansion of the material to improve the brake performance, avoiding surface corrosion of the friction material, greatly dispersing the acting force on the friction from the environment so as to have a good buffer and a rebound effect, and acquiring a breaking effect immediately, does not harm the dual, and can reduce noise.

Description

technical field [0001] The invention relates to a comprehensive friction material. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It mainly includes brake linings (brake pads) and clutch facings (clutch plates). Brake pads are used for braking and clutch plates are used for transmission. Any mechanical equipment and various moving vehicles must have braking or transmission devices. Friction material is a key part of this kind of braking or transmission device. Its main function is to absorb or transmit power through friction, such as clutch plates transmit power, and brake plates absorb kinetic energy. They enable mechanical equipment and various motor vehicles to work safely and reliably. So the friction material is a widely used and even critical material. [0003] However, the existing friction materials generally have poor strength, large product w...
