Problems solved by technology

The former uses a large amount of basalt fiber, and the basalt fiber needs to be spun into fabrics, which increases the production cost or process complexity
The latter uses short-cut fibers, which have certain shortcomings in mechanical properties such as bending strength and strain compared with products made by winding continuous fibers.

Embodiment Construction

[0024] The present invention is mainly realized through the following technical scheme, and the formula of each component is as follows in parts by weight: 10-20% of water-soluble phenolic resin, 0.5-1.5% of aluminum oxide, 4-8% of flake graphite, and 0.6-20% of antimony trisulfide 1.2%, heavy calcium carbonate 6~10%, chalcopyrite powder 8~12%, magnetite powder 6~10%, vermiculite powder 3~8%, barium sulfate 12~18%, powdered nitrile rubber 6~ 15%.

[0025] Mix the above materials together, prepare a suspension with water as a solvent, the amount of water is 5 to 6 times the weight of the water-soluble resin, and then impregnate 15 to 25% of continuous basalt fibers with this suspension, and then After drying, winding, hot pressing, heat treatment, mechanical processing and other processes to make products.

[0026] Brief introduction of basalt fiber: after basalt rock is melted at 1450℃~1500℃, it is a continuous fiber drawn at high speed by a platinum-rhodium alloy wire drawin...

Abstract

The invention discloses a clutch facing piece for an automobile and a production method thereof. The production method comprises the following steps: stirring 10-20% of water soluble phenolic resin, 0.5-1.5% of alumina, 4-8% of crystalline flake graphite, 0.6-1.2% of antimony trisulfide, 6-10% of ground calcium carbonate, 8-12% of chalcopyrite powder, 6-10% of magnetite powder, 3-8% of vermiculitepowder, 12-18% of barium sulfate, 6-15% of powder nitrile-butadiene rubber and water according to parts by weight of each component, preparing suspension, then dipping 15-25% of basalt fibre and obtaining a product by drying, winding, pressing, heat treatment and mechanical processing. By using the invention, the temperature resistance and the wear resistance of the clutch facing piece for the automobile are enhanced, a phenomenon of dust raising in the production and use process is reduced, and the product is more affinitive to the environment.

Description

technical field [0001] The invention relates to an automobile transmission system, in particular to an automobile clutch face and a production method thereof. technical background [0002] Automobile clutch face is a key component in the automobile transmission system, and its main function is to realize power transmission through friction. The current automobile clutch face generally uses copper core-spun yarn as a reinforcement. This core-spun yarn uses a copper core as a carrier and is coated with glass fiber or a hybrid of glass fiber and acrylic fiber. . These coating materials, especially glass fiber, have a strong stimulating effect on human skin. During the production process, since the core-spun yarn is composed of binary or ternary materials, the coating material on the surface is easy to fall off and form dust. It has caused great harm to the production environment of the workshop and the occupational health of workers. [0003] Due to the poor wettability of w...
