Problems solved by technology

However, among the existing friction materials, asbestos friction materials are generally used, which have poor braking performance and unstable braking; during the braking process, the friction materials have high hardness and weak wear resistance, resulting in working noise of the friction materials. Too large, and too much dust is generated during the working process; in addition, the asbestos friction material has a large thermal decay and poor high temperature recovery performance

Abstract

The invention relates to a multi-metal friction material. The multi-metal friction material comprises resin, carbon, a fiber material, inorganic mineral and at least two metal materials, wherein the inorganic mineral includes one or more of wollastonite, feldspar and alumina; and the metal materials contain reduced iron powder and ferrochrome. The friction material prepared by adopting the above formula has good braking performance and good abrasion resistance, so stationary braking can be realized in the automobile braking process, and dusts caused by friction of the friction material in the braking process are reduced; and the friction material also has the advantages of moderate hardness, small thermal recession, good high-temperature recovery performance, reduction of noise pollution, and improvement of the performances of an automobile brake system.

Description

technical field [0001] The invention relates to a production formula for engineering components used in friction work, in particular to a production formula for friction materials in brakes or clutches in brake systems and transmission devices in mechanical equipment and motor vehicles. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It is mainly used in brake linings for braking and clutch facings for transmission. Any mechanical equipment and various moving vehicles must have braking or transmission devices, and friction materials are key components on such braking or transmission devices. The main function of friction materials is to absorb or transmit power through friction. They enable mechanical equipment and various motor vehicles to work safely and reliably. Therefore, friction material is a widely used and critical material. However, among the ex...
