Abstract

A high-performance organic fibre brake pad comprises the following components according to weight percentages: 5-9% of cashew nut oil friction powder, 4-8% of chromite, 7-10% of barite, 4-7% of calcined petroleum coke, 3-7% of crystalline flake graphite, 3-6% of sepiolite fibre, 4-7% of ceramic fibre, 1.5-3% of antimony sulphide, 4-7% of red copper fibre, 3-5% of glued aluminium silicate fibre, 1-2% of alumina fibre, 8-11% of vermiculite powder, 9-13% of organosilicone phenol-formaldehyde resin, 1-2% of carbon fibre, 5-7% of bastose, 1-2.5% of wood pulp cellulose, 3-6% of viscose fibre, 6-9% of bamboo carbon fibre, 3-5% of nitrile rubber and 0.3-0.5% of zinc oxide. The invention has the advantages of light weight, strong wear resistance, good flexibility, low noise and long service life, and the like, and the friction performance is stable at operating temperature between 100 DEG C and 450 DEG C.

Description

technical field [0001] The invention relates to an automobile brake pad, in particular to a high-performance organic fiber brake pad. Background technique [0002] The semi-metal or metal-less brake pads currently on the market have many shortcomings. For example, in wet weather, the brake pads are prone to rust, and if they are not used for a long time, it is easy to cause the brake system to lock. In addition, when the semi-metallic or less-metallic brake pads brake, the noise is higher, and the damage to the brake drum or brake disc is greater. And it is easy to generate dust, which is adsorbed and accumulated on the wheel hub, which is easy to cause corrosion of the wheel hub. [0003] Although organic fiber brake pads can solve the above problems, the existing organic fiber brake pads are not very good in heat dissipation and wear resistance, and their friction performance changes greatly under low or high temperature conditions, and braking may occur after repeated br...
