摘　　要：将微波辐射改性胶粉与聚苯乙烯(PS)共混,通过扫描电镜(SEM)、衰减全反射红外光谱(ATR-FTIR)、X射线衍射(XRD)、拉伸和冲击试验等研究改性胶粉/PS共混材料的结构和力学性能。结果表明,当改性胶粉质量分数为8%时,改性胶粉/PS材料的冲击强度比PS的强度提高了183%,共混材料中改性胶粉以橡胶相分散在PS基体中,二者之间界面粘结良好。The blends were prepared from polystyrene（PS） with waste rubber powder（WRP） modified by the microwave.The structure and mechanical properties of the blends were investigated by SEM,ATR FTIR,XRD,tensile test and impact test.The results show that the impact strength of MRP/PS blend was 183% higher than that of the pure PS when the content of MRP was 8%.Since MRP dispersed at the rubber phase in the PS matrix and MRP was compatible with PS matrix,the toughness of PS showed some improvement.
