Abstract

The invention provides an improved automobile friction material. The improved automobile friction material is prepared from the following raw materials in parts by weight: 3-5 parts of polypropylene ester, 2-4 parts of a dispersant, 6-9 parts of modified polypropylene, 4-6 parts of hydroquinone, 5-8 parts of a friction performance conditioning agent, 9-18 parts of mica powder, 6-10 parts of graphite powder, 4-9 parts of high-strength carbon fibers, 11-16 parts of hollow glass micro-beads, 2-6 parts of glass fibers, 5-10 parts of an anti-rusting agent and 3-6 parts of polyamide. The improved automobile friction material provided by the invention has the beneficial effects that the thermal dilatation coefficient, the thermal conductivity and the shrinking percentage of a product can be effectively controlled, the stability of the product size is increased, the friction performance is good and the production cost is low.

Description

technical field [0001] The present invention relates to an improved automobile friction material. Background technique [0002] Friction materials are widely used in various transportation vehicles (such as automobiles, trains, airplanes, ships, etc.) and brakes, clutches and friction transmissions of various machinery and equipment. According to the function and installation position, it is mainly divided into brake lining and clutch facing. Friction materials are key safety parts in the automobile industry. The starting, braking and parking of automobiles are inseparable from friction materials. It goes without saying. However, there are some defects in traditional automobile friction materials, such as asbestos automobile friction materials, because asbestos is a kind of natural mineral fiber, it has high heat resistance and mechanical strength, asbestos has certain dangers to human health, no asbestos It is easy to rust and produce braking noise. Improved technology ...
