一种可降解高流动PC/PLA合金材料及其制备方法
摘要：
本发明属于高分子材料改性技术领域，提供了一种可降解高流动PC/PLA合金材料及其制备方法，该可降解高流动的PC/PLA合金材料按重量百分比由下列原料制成：聚碳酸酯45‑80％、聚乳酸5‑35％、相容剂PETG‑G‑PLA2‑10％、增韧剂3‑10％、其他助剂0.2‑1％。按上述重量百分比称取各原料后，混合均匀，经螺杆挤出机熔融挤出、造粒，得到可降解高流动PC/PLA合金材料。本发明的方法工艺简单、成本低廉，得到的可降解高流动PC/PLA合金材料具有高流动性、高韧性、易成型及抵抗缺口冲击的能力强的特点，另外，由于添加了PLA，具备生物可降解性，对环境更加友好，符合目前材料的发展方向。
摘要（英）：

The invention belongs to the technical field of high polymer material modification and provides a degradable high-flowability PC/PLA alloy material and a preparation method thereof. The degradable high-flowability PC/PLA alloy material is prepared from the following raw materials in percentage by weight: 45-80% of polycarbonate, 5-35% of polylactic acid, 2-10% of compatilizer PETG-G-PLA, 3-10% of a flexibilizer and 0.2-1% of other auxiliaries. After the raw materials are weighed in the percentage by weight, all the raw materials are mixed evenly, melt-extruded by use of a screw extruder and pelletized, and therefore, the degradable high-flowability PC/PLA alloy material can be obtained. The preparation method of the degradable high-flowability PC/PLA alloy material is simple in process and low in cost; the obtained degradable high-flowability PC/PLA alloy material has the characteristics of high flowability, high toughness, formability and high notch impact resistance; in addition, due to the addition of PLA, the alloy material has biodegradability, is more friendly to the environment and conforms to the development direction of materials at present.
