摘要

以聚己二酸-对苯二甲酸丁二醇酯（Poly（butylene adipate-co-terephthalate），PBAT）为增韧材料，利用熔融共混复合技术，制备了生物可降解的麦秸粉/聚对苯二甲酸丁二醇酯（Poly（butylene succinate），PBS）-PBAT复合材料，并对其进行辐照交联。考察PBAT质量分数和,60,Co γ射线辐照不同吸收剂量对麦秸粉/PBS-PBAT复合材料的热学性能、力学性能和凝胶量的影响。结果表明：当PBAT的质量分数为30%时，麦秸粉/PBS-PBAT复合材料的冲击强度提高了13%；随吸收剂量的增大，麦秸粉/PBS-PBAT复合材料的力学性能和凝胶含量均得到了提高。麦秸粉/PBS-PBAT复合材料经,60,Co γ射线辐照后，完全热分解温度达到550℃，提高了约50℃。

Abstract

The biodegradable wheat straw powder/PBS[poly (butylene succinate)]-PBAT[poly (butylene adipate-co-terephthalate)], composites were prepared by melt-blending, wherein PBAT served as the toughening material. The composites were then subjected to γ-ray irradiation. The effects of PBAT content and different absorbed doses of ,60,Co γ-ray irradiation on the thermal properties, mechanical properties, and gel content of the wheat straw powder/PBS-PBAT composites were studied. The results showed that the impact strength of the composite increased by 13% when the mass fraction of PBAT was 30%. The mechanical properties and gel content of wheat straw powder/PBS-PBAT improved with increasing absorbed doses. The complete thermal decomposition temperature of the wheat straw powder/PBS-PBAT composite irradiated by ,60,Co γ-rays was 550℃, which increased by 50℃ or so.
