Embodiment Construction

[0011] The following takes the production of 100 kilograms of rubber-free wound clutch facings as an example to further describe the present invention:

[0012] The raw material structure is: (calculated by weight)

[0013] 1. Fiber cloth 35

[0014] 2. The formula of cashew nut shell oil resin slurry is as follows:

[0015] Cashew nut shell oil resin 18

[0016] Barium sulfate 15

[0017] Wollastonite powder 10

[0018] Kaolin 10

[0019] Calcium carbonate 7

[0020] Friction powder 3

[0021] Graphite 3

[0022] Carbon black 1

[0023] Xylene 17

[0024] The production is carried out according to the weighing of the formula, and the production process is as follows: (The relevant raw materials evaporate 19Kg during the production process)

[0025] 1. Beating: Put the weighed cashew nut shell resin, barium sulfate, wollastonite powder, kaolin, calcium carbonate, friction powder, graphite, carbon black, and xylene into the beater one after another, and beat them into uniform cashe...

Abstract

The invention discloses a formula and its technique of non-rubber wound formed clutch piece as the structure of composite material of cashew oil resin slurry and winding fiber textile, which is characterized by the following: reducing the consumption of petroleum because not synthesizing rubber and solvent petroleum; saving the manufacturing cost of the product greatly; releasing the pressure of petroleum inlet to certain extent; adopting pure cashew oil as raw material without phenol; improving the elasticity, flexibility and mechanic strength; making each property reach the technical demand of GB5764-1998 'automobile clutch piece' national standard regulation and industrial mechanic amianthine friction disk GB11834-2000.

Description

1. Technical Field [0001] The formula and process of a non-rubber-wound clutch face sheet relate to the field of transportation machinery and polymer composite materials; especially to the technical field of automobile friction materials. It is used in automobile, tractor, engineering machinery and other mechanical clutches and brakes. 2. Background technology [0002] The current market products use rubber as the main raw material. Under the condition of very tight resources, the clutch facings produced by using phenolic resin instead of rubber are too hard and have no elasticity, and are prone to jitter and slippage during use. Such products have basically been eliminated. With the gradual depletion of petroleum and other disposable resources worldwide, the replacement of disposable resources with renewable resources is becoming an important research topic and development trend in the world; with the soaring world oil prices, the synthetic rubber and solvent gasoline Prices hav...
