Abstract

A rust resistance semi-metallic brake pad comprises the following components according to parts by weight: 3 to 5 parts of tire powder, 3 to 5 parts of expansion graphite, 6 to 10 parts of superfine iron oxide powder, 9 to 13 parts of phenolic resin, 15 to 20 parts of stainless steel short fibre, 2 to 3 parts of cashew nut shell oil friction-type mix, 3 to 5 parts of foam ferrous powder, 3 to 5 parts of graphite particle, 10 to 15 parts of barites (600 meshes), 3 to 5 parts of chromite, 2 to 4 parts of magnetite, 3 to 5 parts of precipitated calcium carbonate, 2 to 3 parts of heavy magnesia, 9to 12 parts of acicular aedelforsite fibre, 1 to 2 parts of antimony sulphide, 0.5 to 1 part of copper sulphide. The invention is stainless, and has the characteristics of high friction coefficient,good and high capacity of temperature and decline resisting, long service life, and the like. The high temperature resistance thereof can reach 450 DEG C, friction coefficient is stable between 0.3 and 0.4, and the cost performance of the brake pad thereof is extremely high, and the brake pad can be especially applied to the front brake of light cars for long time and frequent use without damagingeither the brake drum or the brake disc.

Description

technical field [0001] The invention relates to an automobile brake pad, in particular to a rust-resistant semi-metallic brake pad. Background technique [0002] Semi-metallic brake pads have high temperature control ability and high braking temperature, and the brake position is fast and accurate. Therefore, it has become one of the non-asbestos friction materials mainly promoted and applied in our country. But at present, the formula design of some semi-metallic brake pads often has a certain degree of blindness. As a result, some inherent shortcomings of semi-metallic brake pads are amplified, such as serious corrosion under the action of moisture, high noise during braking, high thermal conductivity, and greater damage to brake drums or brake discs. Therefore, how to make semi-metallic brake pads rust-resistant, and have high and stable friction coefficient, low wear rate, and low-cost performance has become the main direction of current semi-metallic brake pad researc...
