specific Embodiment approach 1

[0010] Specific embodiment 1: Use subtropical sisal fiber to spun yarn, and then composite aluminum-nickel alloy fiber to weave cord fabric. In this cord fabric, the mass ratio of the subtropical sisal fiber is 90%, and the mass ratio of the aluminum-nickel alloy wire is 10%. Select thermosetting cashew nut shell liquid powdered resin, water-soluble liquid phenolic resin modified by nitrile rubber, and nitrile latex as bonding materials. In the adhesive material, the thermosetting cashew nut shell liquid powdered resin accounts for 27% by mass, the water-soluble liquid phenolic resin modified by nitrile rubber accounts for 53% by mass, and the nitrile rubber latex accounts for The mass ratio is 20%. Use abrasive fillers such as barite, calcium carbonate, cryolite, chromite, and non-abrasive fillers such as antimony sulfide, graphite, and molybdenum disulfide as functional fillers. In the filling material, the mass ratio of the abrasive filler is 85%, and the mass ratio of the non-...

specific Embodiment approach 2

[0011] Specific implementation manner 2: Use subtropical sisal fiber to spun into yarn, and then compound aluminum-nickel alloy wire to weave into cord fabric. In this cord fabric, the mass ratio of the subtropical sisal fiber is 98%, and the mass ratio of the aluminum-nickel alloy wire is 2%. The bonding material, filling material and processing technology are the same as in the first embodiment. In the finished automobile clutch face sheet (hereinafter referred to as "finished product 2"), the above-mentioned cord fabric mainly made of natural subtropical sisal fiber accounts for 31% by mass, binding material accounts for 28% by mass, and filler material accounts for The mass ratio is 41%.

specific Embodiment approach 3

[0012] Specific implementation mode 3: Use subtropical sisal fiber to spun into yarn, and then composite aluminum-nickel alloy wire to weave cord fabric. In this cord fabric, the mass ratio of the subtropical sisal fiber is 96.5%, and the mass ratio of the aluminum-nickel alloy fiber is 3.5%. The bonding material, filling material and processing technology are the same as in the first embodiment. In the finished automobile clutch face sheet (hereinafter referred to as "finished product 3"), the above-mentioned cord fabric mainly made of natural subtropical sisal fiber accounts for 32% by mass, binding material accounts for 27% by mass, and filler material accounts for The mass ratio is 41%.

Abstract

The invention relates to a method for producing automobile clutch facing patches. The particular technological steps of the method comprise the following: weaving natural vegetable fiber and metal wires into twill fabrics, and mixing and stirring hot setting cashew nut shell oil flaky resin, butadiene-acrylonitrile rubber modified water soluble phenol liquid resin, NBR latex, filling materials and water into slurry, and the like. Compared to the prior art, the method has the following advantages: firstly, the method has the characteristic of environmental protection; secondly, the method has low cost; thirdly, the method overcomes the defects of low high-temperature resistance of the prior process products; and finally, the products produced by the method has obvious performance advantage, namely good high-temperature resistant performance and high strength on rotation bursting resistance.

Description

Technical field [0001] The invention relates to the technical field of manufacturing clutch facings for automobiles. Background technique [0002] The composition of automobile clutch facings can be divided into three categories, namely, skeleton materials, bonding materials and filling materials. In the selection of frame materials for automobile clutch panels, for a long period of time, almost all of the industry has used asbestos fibers. Later, due to the harm of asbestos dust to people, people began to develop non-asbestos clutch facings, using other fiber materials to replace asbestos. Among these alternative fiber materials, glass fiber is the most common application. However, the problem of the glass fiber clutch surface is that, first, it causes pollution in the production process and harms human health; second, the surface of the glass fiber is smooth and the texture is brittle and hard, the impregnation and adhesion are poor, the product wears high, and the friction coe...
