摘要
以Joncryl ADR-4370F(ADR)为增容剂,超细滑石粉(Talc)为成核剂,聚乳酸(PLA)/聚对苯二甲酸-己二酸-丁二醇酯(PBAT)通过熔融共混,然后挤出吹膜。对PLA/PBAT薄膜的热性能、结晶行为、撕裂断面形态、力学性能和阻隔性能进行了研究。结果表明,PBAT的加入改善了PLA的柔韧性。随着PBAT含量(40%~70%)的增加,薄膜的拉伸强度和模量降低,断裂伸长率大幅增加了。薄膜的氧和水蒸气阻隔性能受PBAT影响不大。ADR的加入使得薄膜材料的相容性得到了提高。
With Joncryl ADR-4370F （ADR） as the compatibilizer and super fine talc powder （Talc） as the nucleating agent, poly（lactic acid） （PLA） /poly（butylene adipate-co-terephthalate） （PBAT） were melt-blended, then extruded into blown films. The thermal properties, crystallization behavior, torn surface morphology, mechanical properties, barrier permeability of the PLA/PBAT blown films were investigated. The results indicate that the addition of PBAT improves the flexibility of PLA. With the increase in PBAT content （40 wt% -70 wt% ）, the PLA/PBAT blown film showed decreased tensile strength and modulus, the elongation at break was greatly increased. The influence of PBAT to oxygen resistance properties and water vapour resistance properties of blown films is little. ADR could enhance the compatibility of the blown film materials.
