Description

一种耐高温PBAT/PLA全生物降解材料
技术领域
本发明涉及降解材料领域，尤其涉及一种耐高温PBAT/PLA全生物降解材料。
背景技术
过去的可降解产品多数用淀粉加PVA(聚乙烯醇)，此材料比较亲水，遇水即溶，过分柔软，挺度不够，不适合制造餐具或盛水容器。以前的餐具等防水一次性用品基本用普通塑料，如PP、HDPE、PET等。这些是防水材料，但却是不可降解的，没有环境友好性，对环境形成“白色污染”。
如果用纯PBAT(聚己二酸/对苯二甲酸丁二脂)\纯PLA(聚乳酸)生产产品，可以获得防水、挺度高、有韧性等性能，但凸显的特点是：1、成本高(每吨约2.8万元)；2、维卡变形温度低(50度-60度)。
发明内容
针对现有技术中的上述不足，本发明提供了一种耐高温PBAT/PLA全生物降解材料，其制备简单，能达到降低成本、保持挺度、韧性、又同时提高了维卡变形温度到100度。
为了达到上述发明目的，本发明采用的具体方案为：
一种耐高温PBAT/PLA全生物降解材料，由下列重量配比的原料制备制成：淀粉40％-50％、PBAT(聚己二酸/对苯二甲酸丁二脂)10％-15％、PLA(聚乳酸)10％-15％、增塑剂5％-18％、偶联剂1％-5％、抗氧化剂3％-5％、扩链剂5％-10％、交联剂3％-5％。
进一步，该材料的制备方法：先将淀粉及偶联剂置于高速混合机中，常温，速度60转每分钟，低速搅拌，时间15-30分钟，使淀粉表面活化，然后加入其他材料，把温度调到90度-100度，高速搅拌15-30分钟，然后置于双螺杆塑料挤出机中挤出造粒，造粒温度190度-200度。
本发明的有益效果为：
防水、挺度高、韧性好、成本低于纯PBAT(聚己二酸/对苯二甲酸丁二脂)/纯PLA(聚乳酸)，本产品由于运用了分子交联技术和分子结晶技术，维卡变形温度可达100度，适用于注塑成型，成型温度：190度-200度，降解时间可控制在3-18个月，PBAT(聚己二酸/对苯二甲酸丁二脂)为全降解材料/PLA(聚乳酸)为玉米淀粉提取物，主要材料可降解物为二氧化碳和水，不会造成环境污染；其他助剂全部可以变成自然界天然的无机物。
具体实施方式
以下通过具体实施例进一步描述本发明，但本发明不仅仅限于以下实施例。在本发明的范围内或者在不脱离本发明的内容、精神和范围内，对本发明进行的变更、组合或替换，对于本领域的技术人员来说是显而易见的，且包含在本发明的范围之内。
一种耐高温PBAT/PLA全生物降解材料，由下列重量配比的原料制备制成：淀粉40％-50％、PBAT(聚己二酸/对苯二甲酸丁二脂)10％-15％、PLA(聚乳酸)10％-15％、增塑剂5％-18％、偶联剂1％-5％、抗氧化剂3％-5％、扩链剂5％-10％、交联剂3％-5％。
该材料的制备方法：先将淀粉及偶联剂置于高速混合机中，常温，速度60转每分钟，低速搅拌，时间15-30分钟，使淀粉表面活化，然后加入其他材料，把温度调到90度-100度，高速搅拌15-30分钟，然后置于双螺杆塑料挤出机中挤出造粒，造粒温度190度-200度。
以上所述仅为本发明专利的较佳实施例而已，并不用以限制本发明专利，凡在本发明专利的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明专利的保护范围之内。
