摘要
为实现聚四氟乙烯材料回收再利用,将压制未烧结的聚四氟乙烯灭弧喷口毛坯进行预加工,收集聚四氟乙烯边角料,通过气流粉碎得到聚四氟乙烯回收粉末(R-PTFE)。添加二硫化钼(MoS_(2))和玻璃纤维(GF)得到R-PTFE+5%MoS_(2)+15%GF复合材料。通过粒度和扫描电子显微镜分析得到粉碎3次的R-PTFE粉末粒度更细。测试复合材料拉伸强度,结果表明,在粉碎3次R-PTFE粉末中添加300目GF粉末得到的R-PTFE/MoS_(2)/GF复合材料的拉伸强度为13.17 MPa,延伸率为352.58,力学性能最优。
To realize the recycling and reutilization of polytetrafluoroethylene(PTFE)materials,the suppressed and unsintered PTFE arc extinguishing nozzle blank was preprocessed,and then its scrap was collected to obtain recycled PT-FE(R-PTFE)powders.The R-PTFE/MoS_(2)/glass fiber(GF)composite were obtained by incorporating 5 wt%MoS_(2)(and)15 wt%glass fiber into the R-PTFE powders.Based on the particle size and scanning electron microscopic analysis results,the R-PTFE powders exhibited a fine particle size after crushing three times.The mechanical test results indicated that the R-PTFE/MoS_(2)/GF composite obtained optimal mechanical performance when incorporating 300-mesh glass fiber powders into the R-PTFE powders after crushing three times,and its tensile strength and elongation at break were13.17 MPa and 352.58%,respectively.
