Problems solved by technology

At present, there are two main types of friction blocks for cars on the market, one is imported original products, which have good wear resistance and braking performance, but the price is high; the other is domestic products, although its price is low, but However, the wear resistance is poor, the heat resistance is not very ideal, the life is short, and the braking performance is not good, which leads to a significant decline in the performance of the brake pads.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a special wear-resistant and heat-resistant friction material for car brake pads. Background technique [0002] Brake pads are the key components of car braking, which are generally composed of steel plates, bonded heat insulation layers and friction blocks. Among them, the comprehensive performance of the friction block will be directly related to the reliability and stability of the car operation. At present, there are two main types of friction blocks for cars on the market, one is imported original products, which have good wear resistance and braking performance, but the price is high; the other is domestic products, although its price is low, but However, the wear resistance is poor, the heat resistance is not very ideal, the life is short, and the braking performance is not good, which leads to a significant decline in the performance of the brake pad.
