Abstract

The invention provides a regenerated automobile braking friction material, which is characterized in that nano modified phenol-formaldehyde resin, nitrile rubber, basalt fiber, silicon carbide and boron nitride to the grinding material scraps of the friction material. According to the invention, the grinding material scraps are developed and utilized, so that the raw material consumption is reduced by more than 25%, the environmental pollution caused by material scraps generated in the processing process of the friction material is avoided, recycling is realized and the product cost is lowered; and at the same time, the shear strength, wearing capacity, performance factor, impact strength and friction factor of the friction material are higher than those of the traditional commercial products, and the product also has the characteristics of braking sensitivity, no noise, and long service life.

Description

technical field [0001] The invention relates to a braking friction material, in particular to a regenerated automobile braking friction material and a preparation method thereof. technical background [0002] Friction converts the kinetic energy and potential energy of a moving object into heat energy, thereby achieving the purpose of slowing down or stopping the object. The trend of scientific and technological development in the 21st century is high speed, environmental protection and energy saving. Therefore, higher requirements are put forward for friction materials. The currently used friction materials are mainly composed of more than 20 kinds of materials such as reinforcing fibers, friction-increasing materials, friction-reducing materials, fillers, resins, etc., which are molded under high-temperature and high-pressure conditions after high-speed vacuum mixing to meet the needs of automobiles at various temperatures, pressures, and speeds. friction braking. The ma...
