Problems solved by technology

[0004] The terrain in Central America is mountainous and humid, and the life expectancy of the brake pads is relatively high, and it is not sprayed with water during use, resulting in high temperature during braking, and the brake pads are prone to thermal wear, and the high temperature is also easy to decompose the resin, resulting in The matrix disintegrates and the wear increases. How to prepare a brake pad with wear resistance, strong adhesion and long service life has become a technical problem that needs to be solved locally.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a 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 of t...
