摘　　要：采用熔融共混挤出的方法,制备不同空心玻璃微珠含量的PS复合材料,研究空心玻璃微珠对复合材料力学性能和热稳定性的影响。结果表明:经过表面处理的空心玻璃微珠与PS的相容性显著提高,空心玻璃微珠质量含量为5%时,复合材料获得最大拉伸强度、弯曲强度和冲击强度。Polystyrene （PS） filled with hollow glass beads （HGB） were prepared by extrusion molding. The effects of the contents of HGB on the mechanical properties and thermal stability of the PS/HGB composite were investigated. The results showed that the compatibility between HGB and PS could be significantly improved after superficial treatment of HGB. In addition, the contents of HGB greatly affected the tensile strength, flexural strength and impact strength of the composites,which were optimum when the contents of HGB were 5 %.
