摘要
制备了不同质量分数双(2,6-二异丙基苯)碳化二亚胺(Carbo D)的聚乳酸(PLA)/聚丁二酸丁二醇酯(PBS)/滑石粉复合材料.通过力学性能测试、端羧基滴定测试、傅里叶变换红外光谱分析、差示扫描量热分析以及水解老化测试研究了复合材料的水解稳定性.结果表明:Carbo D的加入可以明显提高PLA/PBS/滑石粉复合材料的耐水解性能,当 Carbo D质量分数为 1.0%时,复合材料综合性能最好,拉伸强度 45.68 MPa,冲击强度 5.54 kJ/m2,在 85℃、85%湿度条件下,经 48h水解老化后复合材料拉伸强度仍达到 31.62 MPa,仅下降了 30.78%.
Abstract
Polylactic acid(PLA)/polybutylene succinate(PBS)/talc powder composites with different mass fractions of bis(2,6-diisopropylphenyl)carbodiimide(Carbo D)were prepared.The hydrolytic stability of PLA/PBS/talc powder composites was studied through mechanical properties test,terminal carboxyl titration test,Fourier infrared spectroscopy,differential scanning calorimetry and hydrolytic aging test.The results show that the addition of Carbo D can significantly improve the hydrolysis resistance of PLA/PBS/talc powder composites.When the mass fraction of Carbo D is 1.0％,the composite material has the best comprehensive performance,with a tensile strength of 45.68 MPa and an impact strength of 5.54 kJ/m2.At 85℃and 85％ humidity conditions,the tensile strength still reached 31.62 MPa after 48 h hydrolysis aging,which only decreased by 30.78％.
