摘要
采用微波辐照工艺和硅烷偶联剂KH550对聚酯[聚对苯二甲酸乙二醇酯(PET)]短纤维进行表面改性,制备改性PET(MPET)短纤维/天然橡胶(NR)复合材料,并对其结构和性能进行研究.结果表明:在微波活化作用下,硅烷偶联剂KH550附着于PET短纤维表面,有利于改善PET短纤维与橡胶基体之间的界面粘合性能;与PET/NR复合材料相比,MPET/NR复合材料的交联密度、定伸应力和撕裂强度增大,拉断伸长率减小,动态力学性能提高.
Abstract
Polyester[polyethylene terephthalate(PET)]short fibers were surface modified by microwave irradiation process and silane coupling agent KH550,modified PET(MPET)short fiber/natural rubber(NR)composites were prepared and their interfacial structures and properties were studied.The results showed that under microwave activation,silane coupling agent KH550 was attached to the surface of PET short fiber,which was beneficial for improving the interfacial adhesion performance between PET short fiber and rubber matrix.Compared with PET short fiber/NR composite,the crosslink density,modulus and tear strength of MPET short fiber/NR composite increased,the elongation at break decreased,and the dynamic mechanical properties were improved.
