摘　　要：本研究将空心玻璃微珠(HGB)引入到全芳香族热固性共聚酯(ATPE)发泡体系中制备了HGB/ATPE复合泡沫,并研究了HGB的含量和泡沫性能对于复合泡沫体系的影响。当玻璃微珠改性后,HGB/ATPE复合泡沫的比强度为26.2 MPa/(g·cm^(-3));HGB的加入也使复合体系热性能和阻燃性能有较大提高,HGB/ATPE复合泡沫的热分解温度、玻璃化转变温度及热变形温度分别为494.18℃、230.47℃和191.00℃,极限氧指数可达到35%~37%。In this study,hollow glass beads(HGB)were introduced into an aromatic thermosetting polyester(ATPE)based foam to prepare HGB/ATPE composite foam,and effect of content of HGB and foaming conditions on the properties of HGB/ATPE composite foam were investigated.After modification,the specific strength of the HGB/ATPE composite foam can reach 26.2 MPa/(g·cm^(-3)),respectively.Moreover,the addition of HGB also greatly improves thermal properties and flame resistance performance of the HGB/ATPE composite foam.The thermal decomposition temperature,glass transition temperature and heat distortion temperature of the HGB/ATPE composite foam are 494.18℃,230.47℃and 191.00℃,respectively,and the limiting oxygen index can reach 35%–37%.
