Abstract

The invention discloses a material for increasing friction plate porosity, and a preparation method thereof. The material for increasing friction plate porosity is prepared from the following raw materials in parts by weight: 30-50 parts of foamed resin, 5-15 parts of modified silicon carbide, 3-12 parts of coal ash, 8-20 parts of tyre powder, 3-10 parts of adhesive, 3-10 parts of foam iron powderand 1-5 parts of cork particle. The material prepared with the preparation method can be added into the friction plate to improve a friction coefficient, a wear rate is reduced, the porosity is improved, and the noise effect of the friction plate is obviously reduced. In addition, the preparation method is simple and is suitable for mass promotion, and a production technical process can be easilyoperated.

Description

technical field [0001] The invention belongs to the technical field of friction plate materials, and in particular relates to a material for increasing the porosity of a friction plate and a preparation method thereof. Background technique [0002] The friction plate is composed of friction materials and adhesives. The friction materials are generally composed of mineral-based inorganic materials and organic materials. Among them, high molecular polymers are binders, and fibrous organic and inorganic components are reinforcing materials. Powdered mineral and organic materials are fillers, and these components are compounded, solidified and processed to make materials with braking functions. For the braking system, one of the most important safety systems of a car, the friction pad is an important part of the entire braking system, which will directly affect the reliability of the braking system. The braking system is made by friction between the brake pad and the brake disc ...
