将与聚乳酸(PLA)化学接枝改性的环氧大豆油(ECP)和乙酰柠檬酸三丁酯(ATBC)作为复合增塑剂,改变ECP和ATBC的含量与PLA熔融共混制备PLA/ECP/ATBC三元共混复合材料,通过差式扫描量热仪、热变形温度测定仪、万能拉伸试验机、水接触角测定仪、洛氏硬度计考察了PLA/ECP/ATBC复合材料的热稳定性、力学性能和亲疏水性能。结果表明,复合材料结晶度最大为14.07%,是纯PLA的8.96倍;缺口冲击强度最大为4.59 kJ/m~2,比纯PLA提高了99.57%;断裂伸长率最大为167.2%,是纯PLA的50.21倍;改变ECP和ATBC的含量可以调节PLA复合材料的亲疏水能力和雾度,能为PLA基体与其他亲水亲油类材料的相容性改性拓宽思路,雾度的改变使...

Taking epoxidized soybean oil (ECP) and acetyl tributyl citrate (ATBC) as composite plasticizers,they chemically grafted with polylactic acid (PLA),and PLA/ECP/ATBC ternary blend composite material was prepared by changing the contents of ECP and ATBC and melt blending with PLA.The thermal stability,mechanical properties and hydrophobic properties of PLA/ECP/ATBC composite materials were tested by differential scanning calorimeter,thermal deformation temperature tester,universal tensile testing machine,water contact angle tester and Rockwell hardness tester.The results show that the maximum cr...
