一种生物基增韧阻燃聚乳酸及其制备方法
摘要：
本发明涉及高分子材料技术领域，尤其涉及一种生物基增韧阻燃聚乳酸组合物及其制备方法。所述增韧阻燃聚乳酸包括具有下述质量份数的各组分：聚乳酸60‑100份，阻燃剂0‑20份，植物油增韧剂0‑20份。本发明采用植物油增韧剂来增韧阻燃聚乳酸，使得聚乳酸再有良好的阻燃性能时还保持良好的韧性，所制得的生物基增韧阻燃聚乳酸组合物具有较高的断裂伸长率和缺口冲击强度。
摘要（英）：

The invention relates to the technical field of high polymer materials, in particular to a biology-based toughened flame-retardant polylactic acid composition and a preparation method thereof. The biology-based toughened flame-retardant polylactic acid comprises the following components in parts by mass: 60-100 parts of polylactic acid, 0-20 parts of a fire retardant and 0-20 parts of a vegetable oil toughening agent. The vegetable oil toughening agent is adopted to toughen flame-retardant polylactic acid, so that polylactic acid maintains favorable toughness while having favorable flame retardancy, and the prepared biology-based toughened flame-retardant polylactic acid composition has high elongation at break and notch impact strength.
