High-temperature resistant material of disc type brake pad

Abstract

The invention discloses a high-temperature resistant material of a disc type brake pad. The high-temperature resistant material is prepared from the following materials in parts by weight: 10-15 parts of phenolic resin, 5-10 parts of sepiolite fiber, 10-20 parts of molybdenum disulfide, 5-10 parts of steel cotton fiber, 5-10 parts of butadiene-acrylonitrile latex, 3-5 parts of friction increasing agent, 3-20 parts of adhesive, 5-15 parts of glass powder, 1-3 parts of butadiene-acrylonitrile rubber, 1-3 parts of graphite particles, 5-10 parts of talcum powder and 10-12 parts of tire powder. By adopting the formula with the components, the porosity can be effectively improved, and the high-temperature resistance of the material is enhanced so as to reduce the decomposition rate of an organic material at a high temperature; meanwhile, the gas escape speed on the friction surface in attenuation can be reduced so that the change rate of the attenuation rate and the frictional coefficient at a high speed is reduced to be within 15%.

Description

technical field [0001] The invention relates to a production formula of a brake pad, in particular to a high-temperature-resistant material for a disc brake pad. Background technique [0002] High-temperature fading performance and high-speed stability are two crucial performance indicators of brake pads, which directly affect the braking safety and comfort of the product. Although the thermal ablation process can improve the recession to a certain extent, it cannot solve this problem, and the ablation is easy to cause other problems, such as: shear force drop, easy to peel off; ablation uniformity; and Product consistency, etc. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a method to change the internal material structure of the brake pad, improve the porosity of the brake pad, increase its strength, and improve the performance of the metal-less brake pad under ...
