Abstract

Provided is a brake pad in a multi-layer composite structure, comprising a steel backing and a brake pad body. The brake pad body is formed by an adhesion thermal insulation layer and a frictional layer. The brake pad is characterized in that the adhesion thermal insulation layer is made of components in the following parts by weight: PROMAXON (R) D calcium silicate, boron containing phenolic resin, magnesium oxide, nano-zinc oxide, nano- alumina, isopropanol, zircon powders, lauryl sodium sulfate, polyacrylonitrile preoxidized fibers, and acrylonitrile butadiene rubber. The frictional layer is made of components in the following parts by weight: Lapinus-Roxul (R) 1000 engineering fibers, aramid fibers, polyacrylonitrile preoxidized fibers, alkali-free bulk glass fibers, calcium sulfate whiskers, potassium titanate whiskers, brass fibers, cashew nut oil frictional powders, flake aluminite powders, tantalum carbide, zirconium silicate, nano-zinc oxide, molybdenum trioxide, and boron containing phenolic resin. The brake pad is characterized by green and environmentally-friendly, good high-temperature resistance and heat fading resistance, good wear-resisting property, stable friction coefficient, long service life, and low cost.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to a brake pad with a multilayer composite structure. Background technique [0002] Today, with the rapid development of the automobile industry, the safety and environmental protection of vehicles are particularly important, and the new requirements for automobile brake pads are constantly increasing. Automobile brake pads are subjected to external pressure to generate friction during work, so that the vehicle can achieve the purpose of deceleration. Therefore, the wear resistance and heat resistance of the material of the brake pad are very important. In addition, the friction materials used in the automobile brake pads we use now contain many heavy metal substances, including antimony, chromium, cadmium, copper, barium, copper and other heavy metals. Every time a car brakes, a small amount of heavy metal dust is released and accumulated in the environment, causing harm. For example, ...
