一种聚乳酸改性复合材料
摘要：
本发明公开了一种聚乳酸改性复合材料，涉及新型材料技术领域。该聚乳酸改性复合材料由聚乳酸、腰果酚和抗氧化剂通过预设工艺参数熔融共混制备得到，聚乳酸改性复合材料中聚乳酸与腰果酚通过‑OH基团的相互作用力复合，从而改善了聚乳酸材料的加工性和力学性能的同时，又不破坏聚乳酸材料的生物质性。本发明提供的聚乳酸改性复合材料在具有较高的断裂伸长率和冲击韧性的同时，还保有聚乳酸材料的生物相容性，从而解决了聚乳酸复合材料的力学性能较低且不稳定的技术问题，达到提高聚乳酸复合材料的力学性能及稳定性的技术效果。
摘要（英）：

The invention discloses a polylactic acid modified composite and relates to the technical field of novel materials. The polylactic acid modified composite is prepared by performing melt blending on polylactic acid, cardanol and an antioxidant through preset technological parameters. In the polylactic acid modified composite, the polylactic acid is compounded with the cardanol through mutual effectof a -OH group, so that the biological qualitativeness of a polylactic acid material is not destroyed while the processing performance and the mechanical performance of the polylactic acid material are improved. The polylactic acid modified composite provided by the invention has keeps the biocompatibility of the polylactic acid material while having relatively high elongation at break and impacttoughness, so that the technical problems of relatively low mechanical performance and instability of the polylactic acid modified composite are solved, and the technical effects of improving the mechanical performance and the stability of the polylactic acid modified composite are achieved.
