Embodiment 1

[0020] This embodiment is used to illustrate the method for preparing a clutch face provided by the present invention.

[0021] Crumble 20 kg of styrene-butadiene rubber into 20-30 mm particles in a crusher, pour the crushed particles into a stirring tank, add 10 kg of gasoline and stir for 15 minutes, then add 2 kg of sulfur, TMTD 0.5 kg, DOP 0.25 kg, feldspar 3 kg, fluorite 5 kg, zircon 7 kg, barium sulfate 14 kg, mica 10 kg, magnesium oxide 4 kg, carbon black 2 kg, natural graphite 10 kg, coke 10 kg , 3 kilograms of phenolic resins, pour in the stirring tank and stir for 80 minutes. The stirred glue and 35 kg of composite core-spun yarn are sizing-coated in the dipping machine, and the sizing-coated fibers are thermally dried for thermal drying, followed by winding, hot-press vulcanization, curing treatment, and subsequent machining Prepare the desired clutch product. The characterization parameters of the friction performance of the clutch face are shown in Table 1, and ...

Embodiment 2

[0023] This embodiment is used to illustrate the method for preparing a clutch face provided by the present invention.

[0024] 20 kg of styrene-butadiene rubber is crushed into 2-20mm particles in a crusher, the crushed particles are poured into a stirring tank, 4 kg of toluene is added and stirred for 15 minutes, and then 2 kg of sulfur and TMTD 0.5 kg, DOP 0.25 kg, feldspar 3 kg, fluorite 5 kg, zircon 7 kg, barium sulfate 14 kg, mica 10 kg, magnesium oxide 4 kg, carbon black 2 kg, natural graphite 10 kg, coke 10 kg, 3 kilograms of phenolic resins were poured into a stirring tank and stirred for 80 minutes. The stirred glue and 35 kg of composite core-spun yarn are sizing-coated in the dipping machine, and the sizing-coated fibers are thermally dried, and then wound, hot-pressed vulcanized, solidified, and subsequently machined to prepare the required Clutch products. The characterization parameters of the friction performance of the clutch face are shown in Table 1, and t...

Abstract

The invention discloses a method for preparing a clutch face sheet, comprising the steps of preparing a rubber slurry and preparing the clutch face sheet by using the rubber slurry, wherein the step of preparing the rubber slurry comprises crushing rubber into rubber particles having a diameter of less than 40 mm, then mixing the rubber particles, filling materials for the clutch face sheet, and an organic solvent capable of dissolving the rubber, and then carrying out coating through reinforced fibers, winding molding, hot pressing sulfuration, subsequent machining and other technologies. The method does not contain rubber mixing steps of banburying and open mixing, reduces the labor intensity in the production of the clutch face sheet, and solves the problem of dust. The prepared clutch product has excellent performance and is prepared with low cost.

Description

technical field [0001] The invention relates to a method for preparing a clutch face sheet for an automobile. Background technique [0002] Automobile clutch face is a key component in the automobile transmission system, and its main function is to realize power transmission through friction. [0003] At present, there are two main processes for preparing clutch face sheets: one is the rubber mixing-calendering method, and the other is the rubber mixing-dipping method. In the production process of these two processes, in order to improve the mixing uniformity of powdery filler and block rubber, it is necessary to mix the rubber, that is, to mix the rubber and filler as the matrix in the internal mixer and the open mixer. Refining, and then through the calendering process or the impregnation process to compound the rubber compound and the reinforcing fiber, and then wind it into a blank and press it into shape. The rubber mixing process in the above process has the disadvan...
