Embodiment 2

[0037] A method for preparing a clutch face blank by using the above-mentioned device, the specific process is the same as in Example 1, the difference is that: wear-resistant particles are added to the basic formula of the rubber, and the wear-resistant particles account for nitrile rubber, phenolic resin, filler 12% of three kinds of raw material gross weights, the formula of wear-resistant particle is as follows (mass fraction): the formula of shown wear-resistant particle is magnesium oxide 5%, zirconium dioxide 3%, rice husk charcoal powder 20%, fly ash 45% %, boron carbide 1.5%, antimony sulfide 5%, liquid rosin resin 3.5%, carboxylated nitrile latex 17%, total 100%. The production method of rice husk charcoal powder is as follows: put the clean rice husk at 280°C and slowly raise the temperature to 560°C at a heating rate of 5°C / min, and accelerate the heating at 560°C to 680°C at a heating rate of 10°C / min. Incubate at 680°C for 1-1.2 hours.

Abstract

The invention relates to a preparation method for clutch facings, in particular to a method for preparing clutch facing blanks by adopting a glue squeezing device. According to the method, the surfaces of framework fiber bundles are continuously wrapped with glue through the glue squeezing device, and operations of glue squeezing, enveloping and winding are conducted synchronously. Specifically, the method includes the first step of mounting; the second step of glue squeezing and enveloping, i.e., glue is squeezed out in advance and placed into a glue particle storage box, the glue squeezing device is preheated to make the temperature of a squeezing head range from 75 DEG C to 95 DEG C, the temperature of a machine body range from 50 DEG C to 65 DEG C and the temperature of a screw range from 45 DEG C to 55 DEG C, then the glue is squeezed in advance, glue squeezing is stopped when the temperature of the glue to be squeezed out ranges from 75 DEG C to 85 DEG C, a pre-squeezing hole is blocked, a glue inlet of the squeezing head is opened, and the glue feeding speed is regulated and is made constant for production after the glue on the framework fiber bundles is uniform; and the third step of winding, i.e., the framework fiber bundles passing through the glue squeezing machine are wound synchronously through a winding machine, so that the clutch facing blanks are obtained.

Description

technical field [0001] The invention relates to a method for preparing a clutch face, in particular to a method for preparing a clutch face blank by using a rubber extruding device. Background technique [0002] At present, the preparation of the wound clutch face generally adopts the wet process-the dipping method, that is, the rubber, resin is dissolved in an organic solvent such as gasoline and mixed with fillers to make a slurry, and the skeleton fiber bundles are impregnated with the slurry through the slurry tank and dried. It becomes a blank, and then the product is obtained through winding, hot pressing and post-processing. In production, rubber requires a large amount of solvent oil, which leads to high production cost and great environmental pollution. At the same time, it is easy to bring safety hazards to production. In addition, it also has the disadvantages of long production cycle for dipping and drying. As an improved method, some manufacturers of clutch fac...
