一种用于一次性餐具的高填充可降解淀粉塑料
摘要：
本发明涉及一种用于一次性餐具的高填充可降解淀粉塑料。该淀粉塑料包括淀粉、增塑剂、聚丁二酸丁二醇酯、玻璃纤维、助剂，由以下方法制备而成：各组分质量比：淀粉35～90％，聚丁二酸丁二醇酯5～50％，增塑剂1～50％，玻璃纤维1～50％，助剂0.1～10％；将淀粉、塑化剂按比例混合均匀，放置1～48h，将聚丁二酸丁二醇酯、玻璃纤维及助剂与上述混料再次混合后，加入到哈克扭矩流变仪中熔融共混，速率为10～100rpm，温度为100～200℃。将共混物在1～50MPa，100～200℃下热压1～10min，于10MPa下冷压1～10min成型。本发明成本低廉，组分简单，加工容易，制成的一次性餐具环境友好。
摘要（英）：

The invention relates to a high-filling degradable starch plastic used in disposable tableware. The starch plastic is prepared from the components of, by mass: 35-90% of starch, 1-50% of a plasticizing agent, 5-50% of polybutylene succinate, 1-50% of glass fiber, and 0.1-10% of an auxiliary agent. The starch plastic is prepared with the steps that: starch and the plasticizing agent are well mixed according to the ratio; the mixture is stood for 1-48h; polybutylene succinate, glass fiber, and the auxiliary agent are mixed with the mixture, and an obtained mixture is subjected to melt blending in a Haake torque rheometer, wherein a speed is 10-100rpm, and a temperature is 100-200 DEG C; the blend is subjected to hot pressing for 1-10min under a pressure of 1-50MPa and a temperature of 100-200 DEG C; and the blend is then molded by cold pressing for 10min under a pressure of 10MPa. The starch plastic provided by the invention is advantaged in low cost, simple components, and easy processing. With the starch plastic provided by the invention, produced disposable tableware is environment-friendly.
