摘要

利用单螺杆挤出机和平板硫化机制备了聚苯乙烯/纳米二氧化钛(PS/纳米TiO₂)的共混物。研究了PS/纳米TiO₂(100/1.5)中聚苯乙烯接枝马来酸酐(PS-MAH)加入量对共混物的拉伸强度、冲击强度、微观结构的影响。结果表明:当PS-MAH加入PS/纳米TiO₂中20g时,共混物的拉伸强度达到最大值。紫外光照射实验结果表明,PS-MAH的加入可有效地提高PS/纳米TiO₂复合材料的抗老化性能,与PS/TiO₂复合材料相比拉伸强度提高30%。

Abstract

Polystyrene (PS)/nano titanium dioxide (TiO₂) composites were prepared by using a single screw extruder and a hydraulic press.The influences of different amount of polystyrene grafted maleic anhydride (PS-MAH) on the tensile strength,impact strength and microstructure of PS/TiO₂ (100/1.5) composites were investigated.The results showed that the tensile strength of PS/TiO₂ reached the maximum value when added PS-MAH was 20g.The results of UV irradiation showed that the addition of PS-MAH could effectively improve the anti-aging properties of PS/TiO₂ composites,and the tensile strength of PS/PS-MAH/TiO₂ increased by 30% compared with that of PS/TiO₂ composites.
