Problems solved by technology

However, semi-metallic friction materials require higher braking pressure to achieve the same braking effect, and the braking heat is transferred to the brake caliper and its components, which will accelerate the aging of the brake caliper, piston sealing ring and return spring. Improper heat reaching a certain temperature level will cause the brakes to shrink and the brake fluid to boil
The more advanced NAO modified low-metal brake pads are different from traditional semi-metallic brake pads. They are made of an organic formula mixed with a small amount of copper or steel for heat conduction and better braking performance, which effectively solves the noise problem , but limited to the performance of the material itself, it is required that its dual material has greater limitations, and at the same time the price is higher

Abstract

The invention discloses a preparing method of a nanoscale compound wear-resisting brake pad. The nanoscale compound wear-resisting brake pad is prepared through heat-alkali treatment, ultrasonic vibrating, microwave ultraviolet treatment and other modification measures of carbon nanotubes, polyphenylene sulfide, zinc oxide, ethylene-propylene-diene monomer rubber and other raw materials.

Description

technical field [0001] The invention relates to a nanoscale composite wear-resistant brake pad, which belongs to the technical field of brake systems. Background technique [0002] The braking system is one of the key components of the car, and the comprehensive performance of the brake pads directly affects the stability and reliability of the braking system. The requirements for high-speed automobiles are getting higher and higher, and correspondingly more stringent requirements are put forward for brake friction materials and structures. Among the friction materials that have been used in China, none of them can fully and comprehensively meet the current performance requirements. As a result, racing cars and imported car parts still need to be maintained by imports. This situation has seriously affected the braking performance of Chinese cars and restricted them. The rapid development of the automobile industry. Therefore, research and development of new brake pad frict...
