High-performance non-asbestos brake pad

Abstract

The invention provides a high-performance non-asbestos brake pad, and further provides a method for preparing the high-performance non-asbestos brake pad. The high-performance non-asbestos brake pad is at least prepared from the following components in parts by weight: 40-60 parts of fibers, 10-15 parts of resin and 35-40 parts of frictional powder. The non-asbestos brake pad is free of asbestos and is healthy and environmentally friendly, meanwhile, waste of non-asbestos clutch surface production is used as the frictional powder to turn the waste into treasure, the production cost, and wastedischarge is reduced.

Description

Technical field [0001] The invention belongs to the field of auto parts, and particularly relates to a high-performance non-asbestos brake pad. Background technique [0002] Asbestos has been used as a reinforcement material for brake pads since the beginning. Asbestos fiber has high strength and high temperature resistance, so it can meet the requirements of brake pads, clutch discs and pads. This fiber has strong tensile strength, can even match with high-grade steel, and can withstand high temperatures of 316°C. More importantly, asbestos is relatively cheap. It is extracted from amphibole ore, and this ore has been found in large numbers in many countries, so asbestos brake pads once became the mainstream of brake pads. [0003] But asbestos brake pads are now basically eliminated, because it has some serious defects. [0004] First of all, asbestos has been confirmed by the medical community to be a carcinogen. Its needle-like fibers can easily enter and stay in the lungs, cau...

[0003] But asbestos brake pads are pretty much out now as it has some serious flaws

[0004] First of all, asbestos has been confirmed by the medical profession as a carcinogen. Its needle-like fibers can easily enter the lungs and stay there, causing irritation, which can eventually lead to the occurrence of lung cancer and seriously endanger health.

[0005] Furthermore, because asbestos is heat-insulating, its thermal conductivity is particularly poor. Usually, repeated use of the brakes will cause heat to accumulate in the brake pads. After the brake pads become hot, their braking performance will change. The plate reaches a certain temperature, and even causes the brake to fail

[0006] Therefore, asbestos brake pads can no longer meet the requirements of modern automobiles for high speed, heavy load, light weight and environmental protection due to their shortcomings such as polluting the environment and poor high temperature stability.
