摘　　要：利用纳米TiO2优异的紫外线屏蔽性能,通过熔融共混法制备了纳米TiO2/ABS复合材料,并进行了人工加速老化实验。分析了纳米TiO2的表面修饰效果,对纳米TiO2/ABS复合材料的冲击性能、色差、光泽以及分子量在老化期间的变化规律进行了研究。结果表明,采用纳米TiO2复合改性后能够使ABS制品较大程度地提高了力学、抗色变和保光性能,使ABS的光降解反应速度及程度得到有效抑制,最终延长ABS制品的户外使用寿命。Due tO excellent ultraviolet shielding ruction of nano-rutile-TiO2, nano-TiO2/ABS composite is obtained by melted and mixed technique. Afterwards nano-TiO2/ABS composite is degraded by accelerated aging test. Moreover modified effect of nano-TiO2 and dispersed status in ABS resin are gained. Simultane- ity some variational laws for nano-TiO2/ABS composite properties are also investigated during accelerated aging test, such as impacting property, color aberration, gloss percent, molecular mass and so on. It is noted that mechanics property of nano-TiO2/ABS composite can make maintenance for a long time, and that the ability of resisting color aberration and gloss percent retainment are improved greatly. Further- more, which can restrain degradative rate and grade effectively, eventually can prolong the survice life of modifed ABS.
