| titleOfInvention | PPS wear-resistant material and preparation method thereof |
| abstract | 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 is mainly prepared from polyphenylene sulfide resin, polytetrafluoroethylene and polytetrafluoroethylene grafted styrene, wherein the styrene content in the polytetrafluoroethylene grafted styrene is 20% -80%. The invention provides a wear-resistant material with good wear resistance and comprehensive mechanical properties: the compatibility of PPS and PTFE is effectively improved by adding the compatilizer PTFE-g-St, so that the mechanical strength and the wear resistance of the material are ensured. By adopting the preferred scheme of the invention, the wear-resisting life of the PPS wear-resisting material prepared by mixing the high-molecular-weight polytetrafluoroethylene and the low-molecular-weight polytetrafluoroethylene in proportion can be prolonged to more than 500 hours; the wear rate is only 0.0025 multiplied by 10 ‑6 mm 3 V (N · m); meanwhile, the mechanical property of the wear-resistant material is not obviously reduced. |
