Abstract

The invention relates to a ceramic-fiber-paper-based friction plate and a production method thereof and aims to provide the friction plate which is high in friction coefficient and fine in wear resistance and the production method which is simple in procedure and easy and convenient for production. According to the technical scheme, the ceramic-fiber-paper-based friction plate comprises ceramic fiber, carbon fiber, aramid pulp fiber, long staple cotton paper, diatomite, cashew shell oil friction powder, calcium carbonate whisker, boron carbide, potassium feldspar powder, rubber granule, iron sulfide, mica, alum, magnesia, cashew shell oil modified phenolic resin, powdered fluorine rubber, butyronitrile rubber latex, boron-tung oil modified phenolic resin and moderate additives. The production method includes the steps of firstly, producing pretreatment material, mixing material and size and performing papermaking to produce raw paper of ceramic-fiber-paper-base friction material; and secondly, soaking the raw paper in adhesive, cutting into strips after hot-pressing solidification, and adhering to a friction plate core plate to obtain the ceramic-fiber-paper-based friction plate.

Description

technical field [0001] The invention relates to a ceramic fiber paper-based friction plate and a manufacturing method of the ceramic fiber paper-based friction plate; moving system. Background technique [0002] At present, the wet friction material commonly used in China is widely used in dry powder metallurgy molding to manufacture nitrile rubber-based wet friction plates. Its advantage is one-time molding, and the powder friction raw material and block rubber material can be fully utilized in the material composition structure, and the production cost is low; the disadvantage is that the pore structure of the friction material cannot be controlled, and the compression rebound performance that affects the friction effect cannot be achieved. Adjustment, low coefficient of friction, large difference in the ratio of dynamic / static friction. Traditional paper-based friction materials mainly use asbestos as a reinforced fiber matrix, which has high tensile strength, high flex...

Problems solved by technology

Its advantage is one-time molding, and the powder friction raw material and block rubber material can be fully utilized in the material composition structure, and the production cost is low; the disadvantage is that the pore structure of the friction material cannot be controlled, and the compression rebound performance that affects the friction effect cannot be achieved. Adjustable, low coefficient of friction, large difference in dynamic / static friction ratio

Traditional paper-based friction materials mainly use asbestos as a reinforced fiber matrix, which has high tensile strength, high flexibility, chemical and thermal erosion resistance of asbestos fibers, and thus is cheap; but asbestos-based paper-based friction materials The high temperature resistance is relatively poor, and asbestos fibers can cause diseases such as asbestosis and pleural mesothelioma, and the use of them has been explicitly banned in China
