摘　　要：以传统的邻苯二甲酸二辛酯(DOP)和聚醚型二甘醇二苯甲酸酯(DEDB)增塑剂作对比,对聚四氢呋喃二苯甲酸酯(PTMGDB_(500))增塑剂增塑的聚氯乙烯(PVC)材料进行研究。本文对增塑剂增塑的PVC材料进行了FTIR和TG表征,并考察了其力学性能、耐乙醇抽出性及耐迁移性。结果表明,增塑剂PTMGDB_(500)增塑的PVC材料在力学性能上介于DOP和DEDB两者之间,而PTMGDB_(500)与PVC间的相互作用更强,在耐迁移、耐乙醇抽出、耐热及耐压等性能方面均优于DOP及DEDB,因此PTMGDB500可作为部分替代DOP和DEDB的增塑剂。Compared with traditional dioctyl phthalate(DOP)and polyether diethylene glycol dibenzoate(DEDB)plasticizers,the polyvinyl chloride(PVC)materials plasticized by polytetrahydrofuran dibenzoate(PTMGDB_(500))plasticizer were investigated including FTIR,TG,mechanical properties,ethanol extraction resistance and migration resistance.In terms of mechanical properties,PVC material plasticized by PTMGDB500 was between those plasticized by DOP and DEDB.Due to the stronger interaction between PTMGDB_(500) and PVC,the properties of PTMGDB_(500) plasticized PVC were better than those of DOP and DEDB in terms of resistance to migration,ethanol extraction,heat resistance and pressure resistance.Therefore,PTMGDB_(500) can be used as a partial replacement of DOP and DEDB plasticizers.
