摘　　要：将高密度聚乙烯(HDPE)与氯磺化聚乙烯(CSM)共混制备热塑性动态硫化弹性体(TPV),并采用高密度聚乙烯接枝马来酸酐(HDPE-g-MAH)作为相容剂来改善HDPE与CSM的相容性,研究HDPE/CSM共混比和HDPE-g-MAH用量对TPV性能的影响。结果表明:随着CSM用量的增大,TPV的力学性能先降低后提高,玻璃化温度(T_(g))升高,阻燃性能改善;添加HDPE-g-MAH后,TPV的力学性能提高,T_(g)降低,HDPE与CSM的相容性较好,CSM粒子在体系中分散更均匀,TPV的拉伸断面更平整。The thermoplastic dynamic vulcanized elastomer(TPV)was prepared by blending high-density polyethylene(HDPE)with chlorosulfonated polyethylene(CSM),and high-density polyethylene grafted maleic anhydride(HDPE-g-MAH)was used as a compatibilizer to improve the compatibility between HDPE and CSM.The effect of HDPE/CSM blending ratio and HDPE-g-MAH amount on the properties of TPV was investigated.The results showed that with the increase of CSM amount,the mechanical property of TPV decreased first and then increased,the glass transition temperature(T_(g))increased,and the flame retardant property was improved.After adding HDPE-g-MAH,the mechanical property of TPV improved,the T_(g)decreased,the compatibility between HDPE and CSM was better,the CSM particles dispersed more evenly in the system,and the tensile section of TPV was smoother.
