Aluminum-core clutch friction plate and preparation method thereof

Abstract

The invention discloses an aluminum-core clutch friction plate and a preparation method thereof. The friction plate is made of an aluminum core frame, and materials of a friction layer comprise the following raw materials in percentage by weight: 5 to 7 percent of phenolic resin, 8 to 12 percent of rubber, 4 to 8 percent of aluminum fiber, 10 to 17 percent of graphite, 1 to 5 percent of friction powder, 1.5 to 3 percent of magnesium oxide, 2 to 6 percent of oil coke, 5 to 15 percent of mineral fiber, 0.1 to 2 percent of stearic acid, 2 to 15 percent of aedelforsite, 2 to 12 percent of molybdenum disulfide, 1 to 10 percent of native cellulose fiber, 1 to 10 percent of curing agent, 0.1 to 2 percent of age inhibitor, 0.1 to 2 percent of antiscorching agent, and 0.1 to 2 percent of accelerating agent. The friction plate has friction resistance, low abrasion and proper friction factor, and can effectively reduce damage generated on the clutch plate in the closing process of the clutch. The clutch has quick separation, tender close and long service life.

Description

technical field [0001] The invention relates to a friction clutch, in particular to an aluminum core clutch friction plate and a preparation method thereof. Background technique [0002] The friction plate of the friction clutch includes a friction layer and a skeleton. Generally, the friction layer material is pre-pressed into a blank, and the processed skeleton is put into a hot-pressing mold for compression molding, and then post-processing such as machining and grinding is performed. The friction plate frame in the prior art generally uses a steel core. [0003] There are at least the following disadvantages in the above-mentioned prior art: [0004] After a long time of friction, the steel core is easy to generate magnetism. When the clutch is separated, due to the magnetic adsorption of the steel core, the separation of the clutch plate is delayed; due to the high hardness of the steel, the clutch will be shortened due to the impact when the clutch plate is closed. ...

[0004] After a long time of friction, the steel core is easy to generate magnetism. When the clutch is separated, due to the magnetic adsorption of the steel core, the separation of the clutch plate is delayed; due to the high hardness of the steel, the clutch will be shortened due to the impact when the clutch plate is closed. service life and even damage the clutch plate
