摘要

摘要: 为了提高聚丁二酸丁二醇酯（PBS）基复合材料的性能，降低生产成本，采用熔融共混法制备了麦秸粉/PBS-聚己二酸-对苯二甲酸丁二醇共聚酯（PBAT）复合材料，利用⁶⁰Co-γ射线对该复合材料进行了辐射改性。研究了辐射改性对麦秸粉/PBS-PBAT复合材料力学性能、热稳定性和热变形温度的影响，并采用FTIR和SEM表征了复合材料的结构和断面形貌。结果表明：当三烯丙基异氰脲酸酯（TAIC）的含量为1wt%时，复合材料经30 kGy剂量辐射后，其拉伸强度、弯曲强度和冲击强度分别提高了20%、23.5%和6.5%；辐射改性提高了复合材料的高温分解速率，使其热变形温度上升了约11℃，并增强了复合材料组分间的粘结性。

Abstract: In order to improve the properties of poly (butylene succinate) (PBS)-based composites and reduce the production cost of PBS-based composites, the wheat straw powder/PBS-poly (butylene adipate-co-terephthalate) (PBAT) composites were prepared by melt-blending method, and then the composites were irradiated by ⁶⁰Co-γ rays. The effects of radiation modification on mechanical properties, thermal stability and thermal deformation temperature of wheat straw powder/PBS-PBAT composites were studied. FTIR and SEM were used to observe the structure and fracture surface morphology of the composites before and after the radiation treatment. Results show that when the triallyl isocyanurate (TAIC) content is 1wt% and the composites are irradiated by 30 kGy dose, the tensile strength, bending strength and impact strength are increased by 20%, 23.5% and 6.5% respectively. The pyrolysis rate of the composites is improved by radiation modification, its thermal deformation temperature rises by about 11℃, and the cohesiveness is strengthened between composite components.
