PBAT改性PLA吸管性能研究

Study on the performance of PLA pipette modified by PBAT

为解决塑料吸管的白色污染问题,开发了基于聚乳酸(PLA)与聚己二酸/对苯二甲酸丁二酯(PBAT)共混的生物降解吸管产品,采用熔融指数仪和微机控制电子万能试验机研究了不同配方组分的吸管改性材料的力学性能,以及吸管产品的使用性能。结果发现,当PBAT含量在10%~20%之间时,吸管的生产成型和使用性能最佳。

In order to solve the white pollution problem of plastic straws,a biodegradable straws product based on the blend of polylactic acid(PLA)and PBAT was developed.The effects of different formulations on the mechanical properties of the modified materials of straws and the service performance of the straws products were studied by melt index instrument and microcomputer controlled electronic universal testing machine.The results show that when the content of PBAT is between 10%and 20%,the pipette has the best performance in production,shaping and use.
