Embodiment Construction

[0009] 1. Preparation of cord fabric

[0010] First, the sisal fiber is spun and twisted, and the twist of the yarn is controlled at about 120 twists, and the thickness of each twisted yarn is controlled at a diameter of 1.8 to 2.3 mm. While twisting, each strand of yarn is added with an aluminum-nickel alloy wire with a diameter of 0.19 mm, so that the mass ratio of the composite fiber yarn composed of sisal fiber and aluminum-nickel alloy wire is 10:1. The sisal fiber yarn containing Al-Ni alloy wires is then woven into a cord fabric for use. It is also possible to replace the aluminum-nickel alloy metal wire with a diameter of 0.19 mm with a copper wire with a diameter of 0.22 mm, and the mass ratio of the sisal fiber to the copper wire is also 10:1.

[0011] 2. Preparation of slurry

[0012] Put the thermosetting cashew nut shell oil powdery resin, the water-soluble phenolic liquid resin modified by nitrile rubber, and the filler into the mixer, and the filler includes a...

Abstract

The invention relates to a method for producing automobile clutch facing patches, which adopts an organic vegetable fiber and other fibers to weave the organic vegetable fiber and other fibers into twill fabrics as a framework material, simultaneously mixes and stirs bonding materials such as water soluble phenol resin, filling materials and water to be prepared into slurry. The method utilizes a natural wood vegetable fiber to replace an inorganic fiber material, and the natural wood vegetable fiber is reproducible and has no pollution. The water soluble phenol resin is used to replace rubber and is taken as a bonding adhesive for preparing the clutch facing patches. Industrial naptha is not used any more. Therefore, compared with the prior art, the method has the following advantages: firstly, the method has the characteristic of environmental protection; and secondly, the method is favorable for reducing the production cost of the automobile clutch facing patches, and solving the problem of product performance fluctuation.

Description

technical field [0001] The invention relates to the technical field of manufacturing automobile clutch faces, in particular to a method for producing automobile clutch faces by using a specific skeleton material and a specific bonding material. Background technique [0002] The composition of automobile clutch face can be divided into three categories, namely skeleton material, bonding material and filling material. In traditional crafts, inorganic fiber materials are used as skeleton materials, and rubber and resin are mainly used as bonding materials. The inorganic fiber material is mostly asbestos or glass fiber. The production process of the automobile clutch face in the traditional process is to mix the rubber, resin and various filling materials evenly through the rubber mixing machine; then add solvent gasoline 1-3 times the weight of the above mixture, and dissolve it Make viscous rubber mortar; then impregnate the skeleton material with rubber mortar to make the s...
