摘要
对超细甲醇制丙烯(MTP)废弃失活分子筛(MTP-DC)表面做有机改性处理,制得有机MTP-DC(M-MTP-DC)。分别以MTP-DC和M-MTP-DC为低密度填料,等规聚丙烯(iPP)为基料,熔融共混制备iPP/MTP-DC和iPP/M-MTP-DC复合材料,采用DSC、XRD、TG、SEM、POM及力学测试仪器等对两种复合材料的结构和性能进行表征。结果表明,MTP-DC和M-MTP-DC对聚丙烯均具有增韧作用,表面有机改性,可使M-MTP-DC在iPP中均匀分散且增韧效果提高。
The surface of deactivated catalysts from the process of methanol to polypropylene(MTP-DC)was organically modified by silane coupling agent to obtain organically modified MTP-DC(M-MTP-DC).iPP/MTP-DC and iPP/M-MTP-DC composites were prepared by using isotactic polypropylene(iPP)as subsrates,and MTP-DC or M-MTP-DC as low-density fillers,respectively.The structures and properties of the two composites were characterized by DSC,XRD,FTIR,SEM,POM and mechanical testing instruments.The results showed that both MTP-DC and M-MTP-DC improve the toughness of polypropylene,and surface organic modification can make M-MTP-DC uniformly disperse in iPP and improve the toughness more.
