Description

一种复合薄膜的制备方法
技术领域
本发明属于塑料薄膜制品技术领域,具体涉及一种复合薄膜的制备方法。
背景技术
塑料因其质轻、强度高、价廉等特性,自20世纪70年代以来就在包装领域得到了快速发展和广泛应用,如塑料袋、食物包装盒和饮料包装等。但是,由于通用塑料本身的化学稳定性,当其被遗弃后会在环境中长期稳定存在,造成大量塑料废弃物在环境中的积累,给环境带来严重的危害,如白色污染、农业白色癌症等问题。
随着环境问题的日益突出,以及人类保护环境的意识的不断提高,塑料废弃物的处理问题,已经成为国际社会广泛关注的焦点。目前解决这一环境问题的办法主要有焚烧法、填埋法和回收利用等。然后,从根本上解决塑料废弃物污染问题、寻求新的问题解决途径,是人类迫切希望实现的。可降解塑料废弃后,可以利用环境中的某些因素发生降解,可以从根本上解决塑料废弃物对环境的污染问题。所谓生物降解塑料是指能被自然界存在的微生物如细菌、霉菌等作用而引起降解的塑料。理想的生物降解塑料除了能保证塑料废弃后可被环境微生物完全分解外、还应该具有优良的使用性能。因此,发展可降解塑料已经成为解决塑料废弃物污染问题的最终途径。
发明内容
本发明的目的在于提供一种在自然环境中易降解的复合薄膜的制备方法,改善日益严重的能源危机和白色污染。
为了实现本发明的目的,采用如下技术方案:

分别称取相应重量份的原料,将高速混合机加热温度调至80℃,转速为450r/min,将淀粉加入高速混合机内,并添加适量的水,运转30min,然后将高速混合机的加热温度升至120℃,转速保持500r/min,将低密度聚乙烯、植物纤维、淀粉、硅藻土、轻质碳酸钙、氧化锌、降解促进剂和增塑剂加入高速混合机内,混合搅拌20min,再把消泡剂加入其中,搅拌10min,关闭高速混合机,冷却至40-60℃,得混合料;将混合料在160-170℃条件下造粒,得到母粒,最后将母粒加入吹膜机内,吹膜温度为120-150℃,吹塑成型,即得复合薄膜。
优选地,植物纤维为玉米秸秆纤维。
优选地,降解促进剂为2,2-双(4-羟基苯基)丙烷。
优选地,增塑剂为甘油或丙二醇。
优选地,消泡剂为乳化硅油。
