PPS wear-resistant material and preparation method thereof

The invention belongs to the technical field of wear-resistant materials, and particularly relates to a PPS wear-resistant material and a preparation method thereof. The PPS wear-resistant material ismainly prepared from polyphenylene sulfide resin, polytetrafluoroethylene and polytetrafluoroethylene grafted styrene, and the content of styrene in the polytetrafluoroethylene grafted styrene rangesfrom 20% to 80%. The invention provides a wear-resistant material with good wear resistance and comprehensive mechanical properties. By adding a compatilizer PTFE-g-St, the compatibility of PPS and PTFE is effectively improved, so that the mechanical strength and wear resistance of the material are ensured. By adopting the preferable scheme of the invention, the wear-resistant life of the PPS wear-resistant material prepared by mixing high-molecular-weight polytetrafluoroethylene and low-molecular-weight polytetrafluoroethylene in proportion can be prolonged to 500 hours or above; the wear rate is only 0.0025*10mm
