摘　　要：用正交实验设计和挤出-注射成型方法制备了纳米CaCO3、钛酸钾晶须、丁腈橡胶改性(丙烯腈/丁二烯/苯乙烯)共聚物(ABS)复合材料,并以缺口冲击强度和弯曲弹性模量为主要指标,通过对正交实验结果的极差和方差分析得到了最佳配方,最后以其为基础制备了防撞护栏材料。结果表明,用挤出-注射成型方法制备ABS复合材料是可行的,正交实验设计、极差和方差分析方法能够有效应用于复合材料的配方优化,其最优方案为A3B3C2D4,所制备ABS复合材料的缺口冲击强度、弯曲弹性模量、弯曲强度和拉伸强度分别比纯ABS提高了39.8%、176%、79.3%和20.1%。Nano-CaCO3/PTW/P83/ABS composite was prepared by the orthogonal experiment design and extrusion-injection molding. An optimum component was gotten by analyzing the variance and range of orthogonal experiment results, while the notched impact strength and bend Young＇s modulus of the material were considered as the two main data. At last, the anti-collision guardrail composite was prepared on the basis of it. Results showed that it was possible to apply extrusion-injection molding to prepare ABS composite, and compounding of composite could be efficiently optimized by the orthogonal experiment design, and variance and range analysis. The best component was A3 B3 C2 D4 , with the material notched impact strength, bend Young＇ s modulus, flexural strength and tensile strength being separately 139.8% ,276% ,179.3% and 120. 1% higher than those of Dure ABS resin.
