Problems solved by technology

[0009] In order to solve the rust problem of the brake pads, it is generally selected to remove metal raw materials from the raw materials at present. Although the rust problem of the brake pads can be solved like this, it will cause the mechanical properties of the brake pads to decrease and reduce the use effect of the brake pads. Therefore, the present invention is in Reduce the amount of metal used to prevent large-scale corrosion of the brake pads and add steel fibers to improve the mechanical properties of the brake pads. The purpose of brake pad rust

Abstract

The invention relates to the technical field of brake pads. The brake pad comprises raw materials including, by weight, 20 parts to 25 parts of ceramic fibers, 5 parts to 10 parts of carbon fibers, 5 parts to 10 parts of steel fibers, 15 parts to 18 parts of modified phenolic resin, 6 parts to 10 parts of calcium oxide, 6 parts to 8 parts of barium sulfide, 15 parts to 20 parts of crystalline flake graphite, 1 part to 3 parts of zirconite, 5 parts to 10 parts of butyl butylbenzene, 10 parts to 15 parts of butyronitrile powder, 3 parts to 5 parts of molybdenum disulfide, 1 part to 2 parts of a bonding agent, 5 parts to 10 parts of blanc fixe, 0.5 part to 3 parts of zinc oxide, 5 parts to 10 parts of rubber powder, 1 part to 2 parts of fluorite powder and 0.5 part to 1 part of silicon carbide. The invention further provides a preparing method of the anti-corrosion brake pad. The method comprises the steps that resin and other powdery materials are put to be mixed and stirred, the fiber materials are added for stirring, hot pressing is carried out, and the brake pad formed through pressing is subject to heat treatment. The brake pad has the beneficial effects of being good in heat resistance, resistant to wear, high in toughness and not prone to corrosion.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to an anti-corrosion brake pad and a preparation method thereof. Background technique [0002] With the rapid development of society and economy, more and more people choose cars as a means of transportation, and the number of cars continues to grow rapidly. However, with the rapid increase in the number of automobiles, the problems caused by automobiles have become more and more obvious, such as traffic congestion, traffic accidents and other problems, which have brought great inconvenience and economic losses to people's lives. Among the hundreds of thousands of traffic accidents every year, nearly 10,000 traffic accidents such as car accidents are caused by brake problems, which directly or indirectly cause huge personal injuries and economic losses. Therefore, the requirements for automobile brake performance are getting higher and higher. [0003] Brake pads are generally c...
