Modified PLLA (Poly Lactic Acid)/PBS (Polybutylene Succinate) composite material

The invention provides a modified PLLA (Poly Lactic Acid)/PBS (Polybutylene Succinate) composite material. The modified PLLA/PBS composite material is prepared by adding POSS (Polyhedral Oligomeric Silsesquioxane)-PLLA and DCP (Dicumyl Peroxide) into the PLLA/PBS material and using reactive melt blending, wherein the mass ratio of the PLLA to the PBS is (80 to 20) to (60 to 40), the content of the POSS-PLLA is 2 to 10phr, the content of the DCP is 0.1 to 0.3phr, the blending temperature is 185 to 195 DEG C, and reaction time is 8 to 15 minutes. The modified PLLA/PBS composite material provided by the invention can sufficiently exert a reinforcing effect of the POSS in the composite material; by adding the DCP, the compatibility between the PLLA and the PBS can be promoted, and a toughening effect of a PBS soft phase in the composite material is more obvious. 本发明提供种改性PLLA/PBS复合材料，通过将POSS-PLLA和DCP加入PLLA/PBC材料中通过反应性熔融共混制备而成；其中，PLLA与PBS的质量比为80:20～60:40；POSS-PLLA的含量为2～10phr，DCP的含量为0.1～0.3phr；共混温度为185～195℃，反应时间为8～1
