摘要 通过单因素和正交优化相结合的方法对微波辅助原位开环法制备核桃壳粉/聚乳酸(WSP/PLA)复合材料的最佳工艺条件进行了研究,结果表明,催化剂辛酸亚锡用量对实验结果的影响最大,WSP质量分数的影响次之,微波参数对实验结果影响较小。最佳工艺条件为单体与辛酸亚锡摩尔比为2 000∶1、WSP质量分数为1.67%、微波功率为350 W、辐射时间为17 min,在该工艺条件下其粘均分子质量Mη=74 972,冲击强度可达1.27 kJ/m2。偏光显微镜分析结果表明,最佳工艺条件下WSP/PLA复合材料有较好的韧性。

Abstract: The optimum conditions for preparation of walnut shell powder/polylactic acid (WSP/PLA) composites through microwave-assisted in-situ ring-opening method are studied by single factor and orthogonal test.It is indicated that the adding amount of stannous octoate catalyst has the greatest influence on the experimental results,followed by WSP content and the microwave parameters.Therefore,the optimum process conditions are as follows:the molar ratio of monomer to stannous octanoate is 2 000:1,the adding amount of WSP is 1.67%,the microwave power is 350 W and radiation lasts for 17 min.Under these conditions,the viscosity average molecular weight of the prepared composites is 74 972 and the impact strength can reach 1.27 kJ·m-2.Analysis results by polarizing microscope show that WSP/PLA composites prepared under the optimum process conditions exhibit good toughness.
