Abstract
本发明公开了一种甲基丙烯酸缩水甘油酯接枝聚乳酸共聚物材料,由以下重量百分比93%~97%的聚乳酸树脂、1%~5%的甲基丙烯酸缩水甘油酯和1%~2%的自由基引发剂的原料制成,可作为一种新型的高效偶联剂,应用在聚酯基复合材料,使得聚酯基复合材料体现出优异性能。本发明还公开了一种甲基丙烯酸缩水甘油酯接枝聚乳酸共聚物材料的制备方法,包括以下步骤:按重量百分比称取聚乳酸树脂、甲基丙烯酸缩水甘油酯和自由基引发剂,混合均匀,作为混合物料;将混合物料加入至双螺杆挤出机中熔融挤出,造粒,得到颗粒产品,具有生产效率高、成本低、无溶剂污染、接枝率高等优点,易于工业化大规模生产,具有较好的经济效益
