High temperature-resistant and wear-resistant PTFE

The invention discloses high temperature-resistant and wear-resistant PTFE. The high temperature-resistant and wear-resistant PTFE is composed of 60%-80% of PTFE, 3%-6% of glass fibers, 2%-5% of a zirconium-titanium alloy, 3%-5% of graphite powder, 3%-5% of tungsten carbide, 4%-8% of polyphenyl ester, 2%-5% of nano-silica, 3%-7% of a silane coupling agent, 1%-3% of a water soluble coupling agent and a composite halogen-free flame retardant. Through use of the glass fibers and nano-silica, the high temperature resistance of PTFE is effectively improved. Through use of the zirconium-titanium alloy, tungsten carbide and water soluble coupling agent, the wear resistance of PTFE is effectively improved. The composite halogen-free flame retardant prevents halogens produced by PTFE combustion andguarantees the property safety of people. 本发明公开了种耐高温耐磨的PTFE，耐高温耐磨的PTFE由PTFE、玻璃纤维、锆钛合金、石墨粉、碳化钨、聚苯酯、纳米二氧化硅、硅烷偶联剂、水溶性耦合剂和复合无卤阻燃剂组成，其配料百分比为：PTFE 60％～80％；玻璃纤维3％～6％；锆钛合金2％～5％；石墨粉3％～5％；碳化钨3％～5％；聚苯酯4％～8％；纳米二氧化硅2％～5％；硅烷耦联剂3％～7％；水溶性耦合
