Abstract

The invention discloses a production method of a multi-copper-wire non-asbestos clutch panel. The production method comprises the following raw materials in parts by weight, 15-25 parts of copper wirereinforcing bodies, 2-4 parts of thickening agents, 3-4 parts of tackifying resins, 16-35 parts of adhesives and 40-60 parts of fillers, wherein the mixed specific gravity of monopotassium phosphate,calcium sulfate, magnesium sulfate, zinc sulfate, aluminum oxide, flake graphite, antimony trioxide, heavy calcium carbonate, chalcopyrite powder, magnetite powder, vermiculite powder and barium sulfate in the fillers is 3:2:1:2:1:1:3:2:1:4:2:3. According to the production method, the specific gravity of each component is strictly controlled, a traditional clutch panel formula is changed, and thecomprehensive performance of the clutch panel is greatly improved; the manufacturing process is simple, and the temperature environment is ensured; the heat resistance is good and can reach more than350 DEG C, the high temperature friction coefficient is stable and the wear rate is low; and the product-related production process has no irritation to a human body.

Description

technical field [0001] The invention relates to the technical field of clutch faces, in particular to a production method of a multi-copper wire-free asbestos clutch face. Background technique [0002] At present, the asbestos-free clutch face sold in the market, in terms of structural design, the skeleton core material of the asbestos-free clutch face is made of ordinary glass fiber plus copper wire (composite wire is made of copper wire with a ratio of less than 15%) to form the skeleton frame core material , Supplemented with binder and friction modifier, the clutch face blank is formed by winding and weaving, and it is made by hot pressing, heat treatment and grinding. Its disadvantages: the combination of the frame core material and the slurry is not good, so that the friction and wear performance of the clutch face product is unstable, and it is easy to cause defects such as large shrinkage and product warping. [0003] For this reason, the application number is CN200...
