Problems solved by technology

[0004] As we all know, there are high mountains and steep roads in Yunnan, Guizhou, Sichuan, and cars are still overloaded when driving, which increases the load on the brakes. There are also great restrictions on the price of brake pads in China. If the price is too high, they cannot be sold. How to prepare a wear-resistant Good performance, stable friction coefficient at high temperature, simple preparation method, low cost, and cheap brake pads have become technical problems that need to be solved.

Abstract

The invention discloses a highly abrasion resistant brake pad which comprises, by weight, 13-16% of modified phenolic resin, 28-33% of fiber materials, 45-55% of filling materials and 3-6% of Sinkiang white vermiculite, wherein the fiber materials are composed of one or more of mineral fibers, glass fibers and paper fibers. The invention further discloses a preparation method of the highly abrasion resistant brake pad. The highly abrasion resistant brake pad is stable in high-temperature friction coefficient and good in abrasion resistance, and the preparation method is simple, low in cost and suitable for Yunan, Guizhou and Sichuan regions and other regions with high mountains, steep roads and large brake loads.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a high wear-resistant brake pad and a preparation method thereof. Background technique [0002] Brake pads are also called brake pads or brake pads. In the braking system of a car, brake pads are the most critical safety parts and play a decisive role in the braking effect. Brake pads are generally made of steel plates, adhesive insulation layers and friction block composition. The friction block is composed of friction material and adhesive. When braking, the friction block is squeezed on the brake disc or brake drum to generate friction with it, so as to achieve the purpose of decelerating and braking the vehicle. It can be seen that the friction block determines the braking performance of the brake pad at high speed and high temperature. The friction material is an important part of the brake pad in the manufacturing process and use process. [0003] The working principle...
