Abstract
本发明涉及一种复合生物降解材料的制备方法，它由聚己内酯，聚乳酸，聚乙二醇经搅拌、双螺杆挤出造粒而成。复合生物降解材料是一种无污染、降解彻底的降解材料，主要应用于医药、农业、以及消费品包装等领域。
Description
技术领域
本发明涉及复合生物降解材料的制备方法。
背景技术
随着经济的高速发展，一次性包装制品、医疗用品、工农业薄膜等，在工农业、日常生活中的广泛应用，致使白色污染已成为人类生存与发展的社会公害。特别是大量生产和使用不可降解的材料，不仅造成资源的巨大浪费，而且严重污染生态环境。现有技术生产的光、生物降解材料，大都是以聚丙烯、聚乙烯添加淀粉或碳酸钙或滑石粉、烯烃润滑剂制得，但是这种工艺属于崩解型，不是全生物降解。
发明内容
本发明的目的是提供一种无污染、降解彻底的复合生物降解材料的制备方法。
本发明的目的是这样实现的；制备方法如下：
(1)、取重量份数比的聚己内酯20-95份，聚乳酸25-100份，聚乙二醇1-5份；
(2)、将上述重量份数比的原料加入搅拌混炼机中，搅拌原料温度到40℃-55℃时，成为预混合料，将预混合料加入同向双螺杆挤出造粒机中拉条切粒包装，制成复合生物降解材料。
本发明取得的技术进步是：本发明组分中微生物降解材料是聚乳酸，是由玉米发酵聚合而成，但是力学性能脆、韧性差。本发明组分中人工合成的生物降解材料是聚己内酯，熔点低，可拉伸强度韧性大，而且是唯一能被水降解的材料。本发明不仅使二种生物降解材料有机复合共混，而且可最大限度地使混合物发挥功能，改变原有组份性质，很好的能按要求对材料性质进行调控，通过复合共混能有效改善材料的力学性质。更重要的是复合后的生物降解材料可以在土壤、水泊中或厌氧条件下完全生物降解，同时还可以回收利用，不会造成环境污染。本发明采用同向双螺杆混炼反应挤出拉条切粒包装一次性完成。
具体实施方式
实施例一：
(1)取聚乳酸20千克，聚己内酯25千克，聚乙二醇1千克
(2)将上述配比的物质加入搅拌混炼机中，搅拌温度到40℃-55℃时，成为预混合料，将预混合料加入同向双螺杆挤出造粒机中拉条切粒包装，制成复合生物降解材料。复合生物降解材料，主要应用于医药、农业及消费包装等领域。
实施例二：
(1)取聚乳酸47.5千克，聚己内酯50千克，聚乙二醇2.5千克
(2)将上述配比的物质加入搅拌混炼机中，搅拌温度到40℃-55℃时，成为预混合料，将预混合料加入同向双螺杆挤出造粒机中拉条切粒包装，制成复合生物降解材料。复合生物降解材料，主要应用于医药、农业及消费包装等领域。
实施例三：
(1)取聚乳酸95千克，聚己内酯100千克，聚乙二醇5千克
(2)将上述配比的物质加入搅拌混炼机中，搅拌温度到40℃-55℃时，成为预混合料，将预混合料加入同向双螺杆挤出造粒机中拉条切粒包装，制成复合生物降解材料。复合生物降解材料，主要应用于医药、农业及消费包装等领域。
Claims (1)
1、复合生物降解材料的制备方法，其特征在于：制备方法步骤如下：
