摘　　要：以ABS为主要原料与PMMA共混来改善ABS的表面光泽度,添加无机填料TiO2和BaSO4来改善ABS/PMMA合金的表面硬度,探讨了PMMA和无机填料含量对ABS/PMMA合金力学性能、光学性能和硬度的影响。结果表明:合金的表面光泽度和硬度随着PMMA含量的增加而增大,但过多的PMMA会降低合金的冲击性能,当PMMA/ABS=30/70时,合金综合性能最佳;加入无机填料后,合金的表面硬度上升,表面光泽度、拉伸强度和冲击强度下降。PMMA was employed to improve the surface gloss of ABS.The inorganic fillers（TiO2 and BaSO4） were added to improve the surface hardness of ABS/PMMA alloy.The effects of use amount of inorganic fillers and PMMA on mechanical property,optical property and hardness of the alloy were investigated.The results show that：the sufrace gloss and hardness of the alloy increase with the increase of PMMA content,but too much PMMA decreases the impact strength of the alloy,when PMMA/ABS=30/70,the general property of the alloy is the best;with the addition of inorganic fillers,the surface hardness of the alloy increases,but the surface gloss,tensile strength and impact strength decrease.
