摘要
采用三种不同的加工工艺制备新型PP/r-PET/WF复合材料,研究了木塑复合材料结构与性能的关系。结果表明,添加经原位微纤化母料所制备的木塑复合材料的力学性能优于其他两种复合材料,且当r-PET的含量为质量分数8%时,复合材料的力学性能最佳;通过SEM观察发现,加工工艺不同,r-PET以不同的微观形态存在于复合体系中,其中以长径比较好的微纤结构存在于三元复合体系时更加有利于复合材料力学性能和耐热性能的改善。
The micromorphology and mechanical properties of three different kinds of PP/r-PET/WF composites has been studied. And the mechanical properties of the r-PET/PP In-Situ microfibrillar composites is the best, when the content of r-PET is 8wt%. Based on the scanning electron microscop(SEM), r-PET has been dispersed uniformly with microfibrillar in the r-PET/PP In-Situ microfibrillar composites, which lead to the good mechanical property and Vicat temperature.
