Abstract

The invention discloses a polymer composite material mixed with radix puerariae fiber powder. The polymer composite material is prepared from the following components in parts by weight: 6 to 12 parts of modified phenolic resin, 5 to 10 parts of nitrile rubber powder, 15 to 21 parts of radix puerariae fiber powder, 10 to 20 parts of graphite, 1 to 3 parts of antimony sulfide, 1 to 3 parts of zinc oxide, 5 to 15 parts of coke, 10 to 20 parts of calcium carbonate, 5 to 15 parts of mullite powder, 5 to 15 parts of clay, 4 to 6 parts of chromite and 1 to 3 parts of alumina. According to the polymer composite material, the radix puerariae fiber powder and the mullite powder with high specific heat are combined to enhance the polymer composite material, so that the mechanical strength of a product is increased, the heat resistance and friction and wear properties of the product can be obviously improved, and the high-performance requirement of the composite material is satisfied; additionally, an extraction process of the radix puerariae fiber powder is simple, sources are wide, the environmental requirement is satisfied, and the polymer composite material prepared from the radix puerariae fiber powder has the advantage of low cost and is suitable for industrialized mass production and use.

Description

technical field [0001] The invention belongs to the field of polymer composite material preparation, and in particular relates to the preparation of a polymer composite material produced by using kudzu root waste residue. Background technique [0002] With the rapid development of the automobile industry, higher requirements are put forward for the development of clutch face polymer composite materials, not only requiring it to have a suitable friction coefficient and wear rate, but also to be environmentally friendly, comfortable and low-cost. Faced with these more stringent requirements, people have found some solutions to improve friction and wear performance, and the use of high-performance fiber-reinforced polymer composites is one of them. [0003] However, many of these methods are at the expense of cost or are not environmentally friendly, and are difficult to produce on a large scale, such as aramid fibers and carbon fibers, especially carbon fibers, which have good...
