Abstract

The invention relates to the technical field of brake pads and discloses a preparation method for abrasion-resistant brake pads. The formula of materials comprises 2123 resin, A330 friction particles,modified large-pad graphite, modified small-pad graphite, powdered coke, butyronitrile powder, barite powder, glass fibers, wood fibers and tire powder. In the preparation process, components of different effects are sequentially mixed firstly, then sulfurization crosslinking is conducted under hot pressing, and then heating for solidification and aftertreatment are conducted to obtain the brakepads. Through the modified large-pad graphite and the modified small-pad graphite, the abrasion-resistant and heat-resistant performance of the brake pads is greatly improved. The prepared brake padsare good in abrasion resistance and heat resistance and stable in friction coefficient.

Description

technical field [0001] The invention relates to the field of brake pads, in particular to a preparation method of a wear-resistant brake pad. Background technique [0002] With the rapid growth of China's automobile production and sales, the level of China's automobile manufacturing and technology has also been steadily developed and improved. It is also a good opportunity and challenge for auto parts suppliers with independent intellectual property rights and research and development capabilities. Brake pads are one of the most common parts in automobiles. Brake pads are composed of steel sheets and friction base materials attached to the steel sheets. purpose of deceleration. Therefore, the wear resistance and heat resistance of the brake pads are very important. [0003] Chinese Patent Publication No. CN102359522B discloses a brake friction plate and its preparation method. The friction plate is composed of the following components in parts by weight: 7-11 parts of res...
