苯氧基环三磷腈对聚乙烯性能的影响

摘要

The effect of phenoxy cyclotriphosphazene (PCPZ) content on flame retardant properties,mechanical properties, rheological properties of linear low-density polyethylene (LLDPE) were investigated.It was found that PCTP was weakly interfacial bonded with LLDPE and dispersed in matrix as particles. The addition of PCTP was favor to increase the flame retardancy and the melting mobility of LLDPE, but it caused decreasing in both ultimate tensile strength and impact strength of LLDPE.%研究了苯氧基环=三磷腈(PCPZ)对线型低密度聚乙烯(LLDPE)阻燃性能、力学性能、流变性能的影响规律.结果表明,PCTP与LLDPE树脂基体界面作用较弱,以颗粒形式分布于基体树脂之中;PCTP的加入可提高LL-DPE的阻燃性能和熔融流变性能,但同时导致拉伸强度、缺口冲击强度下降.
