[0015] Fan composite material bearing sleeve, which is prepared from ultra-high molecular weight polyethylene resin, graphite, polytetrafluoroethylene, calcium fluoride, magnesium oxide and copper powder, the parts by weight of each component are: ultra-high molecular weight polyethylene 100 parts of resin (molecular weight: 2 million), 2 parts of graphite, 2.3 parts of polytetrafluoroethylene, 2 parts of calcium fluoride, 1 part of magnesium oxide, and 2 parts of copper powder.
[0016] The preparation method is as follows: Weigh various raw materials and mix them uniformly to obtain a mixture; mold the mixture into a desired shape in a cold press mold (that is, the shape required for making a bearing sleeve, which is a known technology), and then sinter and shape it. Get the mould; cold press pressure 80Kg / cm 2 , the sintering temperature is 320°C; the mold after sintering is hot-pressed, and the hot-pressing pressure is 80Kg / cm 2 , hot-pressed at 180°C, cooled naturally to...
