摘要
以高抗冲聚苯乙烯(HIPS)/高密度聚乙烯(HDPE)=70/30(质量比)作为研究对象,利用DCP及SEBS的协同作用,考察了不同加料方式,DCP,SEBS含量,加工温度,螺杆转速等条件对共混物性能的影响。结果表明:m(HIPS)/m(HDPE)/m(SEBS)=70/30/10,DCP用量为HIPS和HDPE总质量的0 06%,挤出加工温度(后部)为185℃,螺杆转速为80r/min时,共混物性能较高。
In this paper,the influences of mixing methods and conditions on the mechanical properties of high impact polystyrene(HIPS)/high density polyethylene(HDPE) blends were investigated.Addition of SEBS and DCP was found to improve blends mechanical properties higher than that of addition of SEBS,DCP respectively.On the basis of m(HIPS)/m(HDPE)=70/30,the effects of SEBS content,DCP content,processing temperature,screw rotation speed on the mechanical properties of HIPS/HDPE blends were studied.The results indicated that the mixing condition for acquiring optimum mechanical properties was that m(HIPS)/m(HDPE)/m(SEBS)=70/30/10,w(DCP)=0.06% of HIPS and HDPE,processing temperature was 185℃ and screw rotation speed was 80r/min.
