摘　　要：以马来酸酐(MAH)为交联剂,将回收纤维素二醋酸酯(CDA)与聚丁二酸丁二醇酯(PBS)共混制备CDA/PBS复合材料。分别通过红外光谱(FTIR)、差示扫描量热仪(DSC)和扫描电镜(SEM)表征了复合材料的结构、性能和形貌,测定了复合材料的力学性能。结果表明,CDA与PBS质量比为9/1,CDA/PBS复合材料的力学性能与PBS相当。MAH含量为2%,CDA/PBS复合材料的断裂伸长率和冲击强度达到68.23%和47.70 kJ/m^2,为纯PBS的2.1和3.1倍。CDA/PBS复合材料将是一种价廉的可完全生物降解塑料。Using maleic anhydride （MAH） as crosslink agent, the cellulose diacetate （CDA）/poly- （butylene succinate） （PBS） composites was prepared through melting with CDA and PBS, in which CDA is a kind of recycled material. The structures and properties of the composites were characterized by FTIR and DSC. The morphology of the composites was observed by SEM. The mechanical properties of the composites were measured. The results show that mechanical properties of the composites with 90wt% CDA and 10wt% PBS are similar to that of PBS. The composites has the optimum mechanical properties when 2wt% MAH is added to the CDA/PBS melt mixing system. The elongation at break and impact strength of the composites are 68.23%and 47.70 kJ/m^2, respectively, which are 2. 1 and 3.1 times of those of PBS. The CDAZPBS composites could be a kind of biodegradable plastic with lower price.
