阅读说明：本技术 塑料专用淀粉的制备方法及其应用 (Preparation method and application of starch special for plastics ) 是由 刘一帆 于 2021-07-12 设计创作，主要内容包括：为了解决淀粉基塑料制品的增塑剂析出及淀粉回生变脆的技术问题,本发明披露了塑料专用淀粉的制备方法及塑料专用淀粉的应用。塑料专用淀粉制备的步骤是：将含有一定水分的淀粉先进行膨化,再进行干燥,然后再粉碎至规定细度,得到塑料专用淀粉。塑料专用淀粉可以不经塑化,直接与塑料母粒熔融混合,制备淀粉基塑料产品。本发明还克服了技术偏见,在制备淀粉基塑料制品时,不添加淀粉塑化剂,但获得的产品性能更好、成本更低。(The invention discloses a preparation method of special starch for plastics and application of the special starch for plastics, aiming at solving the technical problems of plasticizer precipitation and starch retrogradation and brittleness of starch-based plastic products. The preparation method of the starch special for the plastic comprises the following steps: the starch containing certain moisture is firstly puffed, then dried and then crushed to specified fineness to obtain the special starch for plastics. The special starch for plastics can be directly melted and mixed with the plastic master batch without plasticizing to prepare a starch-based plastic product. The invention also overcomes the technical prejudice that the starch plasticizer is not added when the starch-based plastic product is prepared, but the obtained product has better performance and lower cost.)
