Description

一种可降解薄膜制备工艺
技术领域
本发明涉及薄膜领域,特别是涉及一种可降解薄膜制备工艺。
背景技术
薄膜是一种薄而软的透明薄片。用塑料、胶粘剂、橡胶或其他材料制成。聚酯薄膜科学上的解释为:由原子,分子或离子沉积在基片表面形成的2维材料。例:光学薄膜、复合薄膜、超导薄膜、聚酯薄膜、尼龙薄膜、塑料薄膜等等,但是现在的薄膜的使用虽然是比较的广泛,但是其便捷的另一面又给我们带来了一个困惑就是,现在的薄膜是不能够降解的,所以给环境带来了特别大的影响,也就是所谓的白色污染,不可降解带来的后果就是这些薄膜会在土地里面呆上很长的时间,阻碍水分的流通,污染土壤。所以在现有的技术只考虑了薄膜的便捷,对环境的危害正在一点一点的变得更加的严重。
发明内容
本发明提供一种可降解薄膜制备工艺,其制作具体步骤为:
(1)原料准备:聚乙烯100质量份,聚碳酸酯10-20质量份,乙烯-丁烯聚合物12-15质量份,聚乙烯蜡5-10质量份,抗氧剂2-4质量份,紫外线吸收剂0.5-1质量份,普鲁兰多糖5-8质量份,PBM降解材料60-80质量份,润滑剂10-30质量份。
(2)将步骤(1)当中的原料放入到200—220摄氏度的加热炉当中1—1.5h,得到原料溶液。
(3)将步骤(2)当中的溶液放到注塑机当中进行塑化。
(4)将塑化之后得到的塑块采用三层共挤设备分别挤压,三层复合共同挤出成型,成型后冷却定型。
优选的,所述聚乙烯由低密度聚乙烯和高密度聚乙烯混合制成,所述低密度聚乙烯和高密度聚乙烯的质量比为5:3混料。
优选的,所述聚乙烯蜡采用PE520。
有益效果:在使用本发明工艺而制作出的一种可降解薄膜,这种薄膜可以在富氧的情况下自动分解,在其废弃之后能够被自然界中微生物完全降解消化,最终生成二氧化碳和水,所以这种可降解薄膜的不会对环境产生过大的影响,可以大批的投入使用,解决了以前薄膜的白色污染的问题。
具体实施方式
为使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解,下面结合具体实施方式,进一步阐述本发明。
(1)原料准备:聚乙烯100KG,聚碳酸酯20KG,乙烯-丁烯聚合物15KG,聚乙烯蜡10KG,抗氧剂4KG,紫外线吸收剂1KG,普鲁兰多糖8KG,PBM降解材料80KG,润滑剂30KG。
(2)将步骤(1)当中的原料放入到200—220摄氏度的加热炉当中1.5h,得到原料溶液。
(3)将步骤(2)当中的溶液放到注塑机当中进行塑化。
(4)将塑化之后得到的塑块采用三层共挤设备分别挤压,三层复合共同挤出成型,成型后冷却定型。
值得注意的是,所述聚乙烯由低密度聚乙烯和高密度聚乙烯混合制成,所述低密度聚乙烯和高密度聚乙烯的质量比为5:3混料,而所述聚乙烯蜡采用PE520。
在使用本发明工艺而制作出的一种可降解薄膜,这种薄膜可以在富氧的情况下自动分解,在其废弃之后能够被自然界中微生物完全降解消化,最终生成二氧化碳和水,所以这种可降解薄膜的不会对环境产生过大的影响,可以大批的投入使用,解决了以前薄膜的白色污染的问题。
显然本发明具体实现并不受上述方式的限制,只要采用了本发明的方法构思和技术方案进行的各种非实质性的改进,或未经改进将本发明的构思和技术方案直接应用于其它场合的,均在本发明的保护范围之内。
