采用液相接枝技术 ,以马来酸酐 (MAH)为单体对高密度聚乙烯 (HDPE)进行接枝功能改性 ,用红外光谱对接枝物进行了表征 .本文研究了聚四氟乙烯 (PTFE)含量对改性 HDPE/ PTFE共混材料的力学性能、加工性能和摩擦性能的影响 ,确定了光纤保护套管的配比 .High density polyethylene (HDPE) was modified functionarily by the liquid-phase grafing method with maleic anhydride (MAH) as a monomer. Grafting product was characterized by IR. The effects of polytetrafluoroethylene (PTFE) content on the mechanical propertiesprocessibility and frictional properties of HDPE/PTFE blend were studied. The recipe used to manufacture fiber optic innerduct were defined
