Problems solved by technology

However, the wear resistance of ordinary phenolic resin is still not ideal, and the brake pads made of it have the defects of high hardness, high brittleness, large curing shrinkage, and large thermal expansion rate, resulting in a significant decline in the performance of the brake pads.

Abstract

The invention discloses a wear-proof brake pad. The wear-proof brake pad comprises a steel plate, a thermal-insulating layer and a friction block. The friction block is fixed to the steel plate through the thermal-insulating layer. The raw materials of the friction block comprise, by weight, 10-20 parts of phenolic resin, 3-12 parts of nitrile rubber, 2-10 parts of butadiene rubber, 5-10 parts of carbon fiber, 3-8 parts of aramid fiber, 2-5 parts of glass fiber, 10-30 parts of potassium titanate lamella crystals, 5-20 parts of iron sodium titanate lamella crystals, 20-40 parts of barium sulfate, 2-5 parts of nano-silica, 2-5 parts of sepiolite, 2-8 parts of alumina powder, 0.2-1.5 parts of accelerant D, 0.1-0.5 part of zinc oxide, 1-4 parts of vermiculite powder, 2-5 parts of petroleum coke, 1-5 parts of synthetic graphite and 3-10 parts of bamboo charcoal. The wear-proof brake pad is excellent in wear resistance and impact resistance, good in heat resistance and small in curing shrinkage.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a wear-resistant brake pad. Background technique [0002] In the braking system of a car, the brake pad is the most critical safety part. Brake pads are generally composed of steel plates, bonded heat insulation layers and friction blocks. Among them, the steel plate should be painted to prevent rust; the heat insulation layer is composed of materials that do not conduct heat; the friction block is composed of friction materials and adhesives, which are squeezed on the brake disc or brake drum to generate friction during braking, and at the same time The friction between the tire and the ground converts the kinetic energy of the vehicle into heat energy after friction, so as to achieve the purpose of deceleration and braking of the vehicle. In the process of automobile braking, the comprehensive performance of the friction material will directly affect the safety and comfort...
