Problems solved by technology

[0003] In the past, the powder metallurgy copper-based friction plates mainly used in China had the disadvantages of low dynamic friction coefficient and large dynamic / static friction coefficient ratio; while the traditional paper-based friction materials introduced mainly use asbestos as the reinforcing fiber matrix, but asbestos fibers can Asbestosis, pleural mesothelioma and other diseases are caused, which is not in line with the green development direction of future friction discs. Therefore, the research and development of paper-based friction discs came into being

Abstract

The invention discloses a paper-based friction plate and a manufacturing method thereof. A coating material of the paper-based friction plate is prepared by taking fibers as a skeleton, resin as a matrix, various oxides and graphite as fillings and organic friction powder and rubber as a regulator through processes of pulping, papermaking, drying, dipping in the resin, curing, laminating on a steel core plate, performing heat treatment and machining. In the production process for the paper-based friction plate, the conventional curing treatment and bonding aftertreatment are combined into 'curing treatment', so the quality and yield of products are improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to a paper-based friction plate and a preparation method thereof, in particular to a machine preparation method for a paper-based friction plate used in clutches and gearboxes. Background technique [0002] The paper-based friction sheet refers to the homogeneous multi-material base paper produced by the wet papermaking process as the base material, and the friction sheet is prepared by die-cutting, dipping, and laminated hot-pressing methods. The paper-based friction sheet is widely used in engineering It is used in the clutch and brake systems of machinery, agricultural machinery, mining machinery, heavy-duty vehicles, cars and ships to transmit torque, decelerate and brake. [0003] In the past, the powder metallurgy copper-based friction plates mainly used in China had the disadvantages of low dynamic friction coefficient and large dynamic / static friction coefficient ratio; while the traditional paper-based friction materials ...
