Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] A method for preparing a high-performance automobile non-asbestos clutch face, comprising the following steps:

[0024] S1. Asbestos-free thread (cloth) impregnated with resin: Dry the non-asbestos thread (cloth) to make the absorbed moisture ≤ 1.5%, and roughen the phenolic resin and hexamethylenetetramine at a mass ratio of 1:1. Mix, and use F-400 pulverizer to make fine powder to obtain pulverized material. Put the pulverized material and alcohol into the mixer according to 1:1.25 mass parts to make a resin solution, put t...

Abstract

The invention discloses a preparation method of a high-performance automobile asbestos-free clutch facing. The preparation method comprises the following steps: S1, dipping of asbestos-free wire (cloth) in resin; S2, preparation of a rubber material, specifically, 1, selection of raw materials; 2, rubber mastication; 3, ingredient filler adding and mixing; and 4, adhesive cement beating; S3, adhesive dipping; S4, blank reeling, hot press molding and heat treatment; and S5, grinding processing, inspection and packing. The preparation method is simple in process, has high strength and high wearresistance, meets various performance indexes which should be achieved during transmission of an automobile when used, is safe to use, comfortable and stable, harmless to human bodies and pollution-free to the environment, and is stable in friction coefficient, low in wear rate and light in specific gravity while energy is saved and consumption is reduced, and when the high-performance automobileasbestos-free clutch facing is used, smooth reunion and small impact are implemented.

Description

technical field [0001] The invention belongs to the technical field of clutch face sheets, and in particular relates to a preparation method of a high-performance automobile non-asbestos clutch face sheet. Background technique [0002] The automobile clutch face is a component material that the vehicle relies on friction to perform the transmission function. It is a kind of friction material and a very important safety part in the automobile. It has an important impact on the realization of the functionality, safety and comfort of the automobile. . The commonly used automobile clutch face is mainly composed of three parts: binder, reinforcing fiber and filler particles. The role of the binder is to connect the reinforcing fiber and filler particles into a whole, that is, the clutch face product; The mechanical properties of the product ensure that the product has sufficient mechanical strength to withstand the impact force, shear force, and high-speed rotation of the clutch...
