Research on Wear Resistant and Self-lubricating Cage Materials Made of PTFE/EkonolSUN Xiao-bo,LI Jian-xing,SHI Lian-wei,WANG Feng,WANG Zi-junLuoyang Bearing Science ＆ Technology Co.,Ltd.,Luoyang 471039,ChinaAbstract:The self-lubricating materials with better wear resistance are prepared by PTFE reinforced with ekonol.The results show that with 20%wt ekonol,the diametric tensile strength is 17.3 MPa,the Shore hardness 64.0,the friction coefficient 0.248 5,and the wear resistance increases 6 times compared with pure PTFE.The cooling rate is controlled,soaking 1 hour in the largest crystallization rate temperature zone,the diametric tensile strength and the wear resistance increases 27.2% and 1.7% respectively.[著者文摘]
