Problems solved by technology

In addition, the heat resistance of asbestos is not good. When the heating temperature reaches above 400 ℃, its mechanical strength drops sharply.
[0004] Glass fiber is an inorganic non-metallic material with excellent performance. There are many types. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance.

Abstract

The invention discloses a non-asbestos high-temperature-resistant clutch surface patch and a manufacturing method thereof. The non-asbestos high-temperature-resistant clutch surface patch is prepared from the following raw materials in parts by weight: 25-35 parts of modified fibers, 6-8 parts of copper fibers, 3-5 parts of aramid fibers, 20-30 parts of acrylonitrile-butadiene rubber, 10-20 parts of phenolic resin, 2-4 parts of a vulcanizing agent, 3-5 parts of an anti-ageing agent, 10-14 parts of graphite, 8-12 parts of barite powder, 6-8 parts of nano silicon dioxide and 3-5 parts of nano titanium dioxide. The non-asbestos high-temperature-resistant clutch surface patch disclosed by the invention does not contain asbestos, and eliminates contamination hazard of the asbestos; and moreover, high temperature resistance is excellent, a friction coefficient is not obviously reduced under a high-temperature condition, and abrasion is relatively low.

Description

technical field [0001] The invention belongs to the field of friction materials, and in particular relates to an asbestos-free high-temperature resistant clutch face and a preparation method thereof. Background technique [0002] The clutch is a key component in the car transmission system. The function of the clutch is to transmit power through friction, to ensure the smooth start of the car, to achieve smooth shifting, and to prevent the drive train from overloading. The clutch face is a functional element that directly generates frictional torque on the clutch, so the clutch face needs to have strong mechanical properties, heat resistance and stable friction performance. [0003] According to the International Labor Organization, at least 100,000 people worldwide die from diseases caused by asbestos every year, and this number is increasing every year. Experts say that when asbestos-containing materials break down, tiny fibers enter the air and create pollution. After a...
