摘　　要：采用7种增韧剂:高胶粉、丙烯酸酯类树脂(ACR),马来酸酐接枝三元乙丙橡胶(EPDM–g–MAH),苯乙烯三元共聚物(MBS),乙烯丙烯酸丁酯(EBA),马来酸酐接枝低密度聚乙烯(PE–LD–g–MAH),乙烯–甲基丙烯酸酯(EMA)对丙烯腈-苯乙烯共聚物(SAN)进行增韧改性,通过高低温实验箱和氙灯人工气候试验箱来研究各增韧剂对SAN耐候性的影响。结果表明,添加增韧剂MBS的SAN冲击强度最高;随着温度的降低,SAN的冲击强度是下降的,EBA,EPDM–g–MAH能改善SAN的低温冲击强度;氙灯光照老化试验结果表明,SAN经过光照老化后都会出现黄变现象,而添加了EPDM–g–MAH,MBS,EBA的SAN的耐光照老化性能都有所提高,其中添加了EPDM–g–MAH的耐光照老化性最好。Using seven different toughness agents in acrylonitrile-styrene copolymer（SAN Resin）was studied, the influence of high glue powder, acrylic resin（ACR）, maleic anhydride grafted EPDM （EPDM-g-MAH）, styrene copolymer（MBS）, ethylene butyl acrylate（EBA）, maleic anhydride grafted PE-LD（PE-LD-g-MAH）and ethylene methyl acrylate（EMA） on mechanical properties of acrylonitrile styrene copolymer（SAN resin）was respectively researched. And temperature test machine and xenon lamp climate chamber were used to analysis of the influence of different toughness agents on the weatherability of SAN. The results show that compared with other toughness agents, the impact strength of SAN resin with MBS is the best. The impact strength of SAN resin is decreasing with the lower temperature, EBA and EPDM-g-MAH could improve the impact strength of SAN resin in low temperature. And Xenon lamp aging test results show that the SAN resin will appear the phenomenon of xanthochroia after xenon lamp aging test, but EPDM-g-MAH, MBS and EBA could improve the light resistance properties of SAN resin, and the effect of EPDM-g-MAH is the best.
