Abstract

The invention provides an environment-friendly friction material and a brake pad and a preparation method based on the environment-friendly friction material. The environment-friendly friction material is composed of the following raw material components of, in percentage by mass, 3%-8% of modified phenolic resin, 9%-32% of steel fiber, 5%-20% of mineral fiber, 1%-5% of aramid fiber, 10%-30% of graphite powder, 1%-5% of flake zinc powder, 5%-20% of barium sulfate, 5%-15% of titanate, 0.5%-3% of aluminum oxide, 5%-15% of zirconium oxide, 2%-20% of granular magnesium oxide, 1%-5% of calcium hydroxide and 3%-15% of rubber-based granular material. The brake pad prepared by the environment-friendly friction material and the preparation method is free of asbestos, free of heavy metal components such as copper, long in service life, stable in braking performance and free of damage to the dual disc and less ash drop; the environment-friendly friction material and the brake pad and the preparation method based on the environment-friendly friction material effectively solves the defects that the service life is reduced, the brake efficiency is reduced, the dual disc is damaged and the like due to the fact that copper is not contained in the prior art.

Description

technical field [0001] The invention relates to the technical field of automobile friction and braking materials, in particular to an environmentally friendly friction material, a brake pad based on the same and a preparation method. Background technique [0002] In recent years, the global automobile industry has developed rapidly. As one of the key components in auto parts, brake pads not only determine the safe and comfortable driving of the car, but also one of the important factors affecting energy conservation and environmental protection in the automotive industry. [0003] With the environmental protection regulations of Washington State and California respectively proposing to restrict the copper content in automobile brake pads, the global brake pad industry has gradually developed towards the direction of environmental protection and copper-free. [0004] Because metallic copper has excellent properties such as high thermal conductivity, anti-wear, and stable fri...
