一种改性聚乳酸复合材料及其制造方法和应用
摘要：
一种改性聚乳酸复合材料，按重量份计，改性聚乳酸复合材料包括以下组分：聚乳酸树脂48~78.6份，无机填料5~15份，玻璃纤维15~30份。无机填料选自空心玻璃微珠和空心陶瓷微珠中的一种或两种混合物，玻璃纤维是直径为5～10μm的连续纤维或短切纤维。所述改性聚乳酸复合材料不仅密度小，还具有耐热性好、机械强度高、拉伸性能好的优点，另外当空心玻璃微珠和空心陶瓷微珠的质量复配比在1:4～1:1范围内时，该聚乳酸复合材料耐热性更好、机械强度更高、拉伸性能更好。本发明的改性聚乳酸复合材料可用作塑料制品。
摘要（英）：

The invention discloses a modified polylactic acid composite material. The modified polylactic acid composite material comprises the following components in parts by weight: 48-78.6 parts of polylactic acid resins, 5-15 parts of an inorganic filler and 15-30 parts of glass fibers. The inorganic filler is selected from one or a mixture of two of hollow glass micro-beads and hollow ceramic micro-beads; and the glass fibers are continuous fibers or chopped fibers with the diameter of 5-10 microns. The modified polylactic acid composite material is small in density and has the advantages of high heat resistance, high mechanical strength and good tensile property. In addition, when the mass compound ratio of the hollow glass micro-beads to hollow ceramic micro-beads ranges from 1:4 to 1:1, the polylactic acid composite material is high in heat resistance, high in mechanical strength and good in tensile property. The modified polylactic acid composite material disclosed by the invention can serve as a plastic product.
