Embodiment Construction

[0008] Concrete steps and principle of production method of the present invention are described in detail as follows:

[0009] First, the continuous fiber cloth composed of organic fiber, metal fiber and glass fiber is impregnated twice through the impregnation system with rubber solutions A and B. Through layer-by-layer penetration, the stress difference between different materials is weakened as much as possible, the bonding ability of the initial dipping solution is enhanced, and the influence of the styrene-butadiene rubber conjugate system on the bonding performance in one dipping is reduced. Since a better adhesive layer is formed on the surface of the skeleton material by first dipping, the second impregnation solution does not need to penetrate further into the inner fiber layer, but only needs to form an outer cladding on the primary impregnation system. The bonding stress is uniform in such a production system. Due to the strong adhesion of the primary system, no ch...

Abstract

A wet method for preparing the clutch disc of car in order to eliminate the stress nonuniformity includes such steps as immersing the continuous fibers (metallic fibers, glass fibers, or mixed fibers) in the rubber solution A and then in rubber solution B, winding, sulfurizing, heat treating, grinding and dusting.

Description

Technical field [0001] The invention relates to a new wet method for producing clutch faces for automobiles. Background technique [0002] At present, the wet production method of clutch facings is to impregnate continuous fibers such as metal fibers, glass fibers, and mixed fibers into the same rubber solution system, and then pass the following processes: winding, vulcanization, heat treatment, grinding, and dust removal to obtain finished products. Because the metal fiber and glass fiber have certain strength, the surface is hard and smooth, and the surface adsorption capacity is weak; the mixed fiber has lower strength, and the adsorption capacity is higher than the former. The rubber impregnation solution currently used is affected by the granular structure of the filler and the result of the styrene-butadiene rubber polymer conjugated system, which hinders the overall penetration of the rubber solution in the system. In this way, the bonding properties of the respecti...
