采用偶联剂对麦秸粉进行表面处理,利用共混技术制备聚丁二酸丁二醇酯(PBS)/麦秸粉复合材料,研究了偶联剂对PBS/麦秸粉复合材料力学性能和降解性能的影响。结果表明:当麦秸粉用量为20%时,PBS/麦秸粉复合材料的力学性能最佳,降解速率也明显提高;偶联剂KH550的改性效果较好,当KH550用量为2%时,较好地改善了PBS与麦秸粉的界面相容性,材料断裂面呈韧性断裂,提高了复合材料的力学性能,而对其降解速率影响不大。
The wheat straw powder was surface-treated with coupling agent, and the polybutylene succinate (PBS) / wheat straw powder composite was prepared by blending technology. The effects of coupling agent on mechanical properties and degradation properties of PBS / wheat straw powder composite Impact. The results showed that when the content of wheat straw was 20%, the mechanical properties of PBS / wheat straw composite were the best, and the degradation rate was also improved obviously. The modification effect of coupling agent KH550 was better. When the dosage of KH550 was 2% Good interfacial compatibility between PBS and wheat straw powder was improved, the fracture surface of the material showed ductile fracture, which improved the mechanical properties of the composites, but had little effect on the degradation rate.
