Abstract

本发明公开了一种全生物降解的塑料淀粉母粒及其制备方法和应用。本发明塑料淀粉母粒包括以下重量份的各组分组成:淀粉60-75份、载体20-30份、相容剂1-5份、润滑剂1-5份、改性剂1-5份和降解促进剂1-5份。本发明塑料母料以淀粉为生物活性物质,添加光、氧、热降解促进剂,在光、氧、热和微生物作用下,具有多重降解的特性。其降解过程为诱导期(可控)过后,制品降解为碎片和粉末,最后与环境同化,在一定环境条件下(有氧)继续降解,最终生成CO<sub>2</sub>和水,进入土壤中不会造成二次污染,降解周期视需要,可通过改变复合降解调节剂和生物活性物质的添加量加以调控。本发明还具有制备工艺简单、生产成本低等优点。
The invention discloses a full biodegradable plastic starch master batch, a preparation method and application thereof. The plastic starch master batch comprises the following compositions in portion by weight: 60 to 75 portions of starch, 20 to 30 portions of vectors, 1 to 5 portions of compatilizer, 1 to 5 portions of lubricant, 1 to 5 portions of modifier and 1 to 5 portions of degradation accelerant. The plastic master batch takes the starch as a bioactive substance which is added with light, oxygen and the thermal degradation accelerant, and has the characteristic of multi-degradation under the action of the light, the oxygen, heat and microorganisms. The degradation process of the full biodegradable plastic starch master batch is as follows: after the induction period (controllable) is over, a product is degraded into chips and powder, assimilated with the environment finally, and is continuously degraded under certain environmental condition (aerobic), and CO2 and water are finally generated and can not cause secondary pollution when entering into soil, wherein the degradation period can be adjusted and controlled as required by change of the addition of a composite degradation regulator and the bioactive substance. The full biodegradable plastic starch master batch also has the advantages of simple preparation technology, low production cost and so on.
