[0019] In view of the shortcomings of the prior art described above, the present invention provides an environmentally friendly friction material for a clutch and a clutch plate based on it and a preparation method to improve the performance of the environmentally friendly friction material and improve the pollution of the environment by the existing environmentally friendly friction material for the clutch. question. The environmentally friendly friction material uses dicyandiamide modified phenolic resin and butadiene rubber powder as bonding materials, and adds high-strength stainless steel fibers and basalt mineral fibers as reinforcing materials. , adding alumina as grinding material to increase the friction coefficient of the clutch plate, using graphite and metal sulfide as lubricating components, protecting the pair and stabilizing the friction coefficient. The clutch plate thus produced has less wear on the pair plate and has a high dynamic and static friction coeffici...

Abstract

The invention provides an environment-friendly friction material of a clutch, a clutch disc based on the environment-friendly friction material and a preparation method. The environment-friendly friction material comprises the following raw material components in percentage by mass: 5%-15% of dicyandiamide modified phenolic resin, 8%-18% of butyl ethylene rubber powder, 5%-10% of stainless steel fibers, 3%-15% of porous foam iron powder, 10%-20% of basalt mineral fibers, 3%-8% of ferromolybdenum alloy powder, 10%-17% of graphite, 3%-8% of metal sulfide. 3%-10% of aluminum oxide, 10%-25% of kaolin and 1-6% of manganese-aluminum compound. The clutch disc is made of the environment-friendly friction material and method, is stable in friction coefficient, low in abrasion and high in product strength, does not have the phenomena of edge falling and block falling in the operation and braking processes, does not contain materials polluting the environment in the product formula, does not pollute the environment in the preparation and use processes, and belongs to an environment-friendly clutch disc.

Description

technical field [0001] The invention relates to the technical field of automobile friction brake materials, in particular to an environment-friendly friction material for a clutch, a clutch plate based on the same and a preparation method. Background technique [0002] The clutch is located in the flywheel housing between the engine and the gearbox, and the clutch assembly is fixed on the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. Clutch discs can be divided into dry clutch discs and wet clutch discs from the way of use; they can be divided into automobile clutch discs, clutch discs, paper machine clutch discs, etc. from the application field, and can be divided into powder metallurgy sintered clutch discs from the properties of friction materials, Resin-based clutch plates, rubber-based clutch plates, paper-based clutch plates. Some clutches in the prior art are copper-based clutch discs, which contain a la...
