摘　　要：研究了不同配方体系的丙烯腈-丁二烯-苯乙烯共聚物(ABS)高胶粉/聚乳酸(PLA)共混合金的力学性能、熔体流动性、注塑加工性,并通过SEM、DMA对ABS高胶粉/PLA共混合金的微观结构、相容性进行了表征。结果表明:ABS高胶粉大大提高了PLA的冲击强度和断裂伸长率,但拉伸强度和模量有所降低;增加ABS高胶粉含量,合金熔体流动性能、注塑加工性能均呈下降趋势;当ABS高胶粉质量分数为10%时,合金的熔体质量流动速率与纯PLA相当,熔体流动性较好,tanδ谱图和SEM照片也表征:此配方体系下的合金相容效果最佳。The mechanical properties, melt flowing property, injection molding process of different ABS/PLA high glue powder alloy were separately studied. The microstructure and compatibility of ABS/PLA were characterized by SEM, DMA. It was found that ABS dramatically improved the impact strength and elongation at break but the tensile stregth and modulus decreased. The melt liquidity and injection molding processing of alloys declined by the increase of ABS; the alloy＇s compatibility was well when the content of ABS high glue powder was 10 wt% , the tanδ spectrogram and SEM micrographs also revealed the best com- patibility of the alloy.
