Description
技术领域
本发明涉及玉米棒芯材料加工技术领域,尤其是一种新型环保玉米棒芯塑料吹瓶母粒及其加工工艺。
背景技术
为了解决不可降解塑料废气物对环境造成的白色污染,许多国家的研究人员都在致力于研究开发环境可降解塑料。目前,用淀粉、纤维素、木质素等填充改性的聚烯烃基复合材料得到广泛关注,这种材料通过土壤中微生物对淀粉、纤维素、木质素等的侵蚀,使这种填充复合材料制品脆化并逐步被降解。
玉米棒芯粉作为玉米淀粉生产过程中的副产品,玉米棒芯有机质含量高达80%以上,粗纤维含量2%~3%,从玉米棒芯成分分析,非常有利于制备有环保材料。而玉米棒芯过去一般作柴烧或者废弃,造成了资源的巨大浪费。
另外玉米棒芯具有价格低廉,来源广泛的特点,其多孔性结构使其具有良好的吸附性能,聚烯烃也可以对其很好的浸润,使其可以和聚烯烃塑料更好的结合。
现有技术中,对玉米棒芯的加工利用主要是在制成饲料方面,如专利103652356A公开了一种玉米棒芯氨化发酵制取复合饲料的工艺,专利102617201A公开了一种利用造纸物化污泥和玉米棒芯生产有机肥的方法等。对玉米棒芯在形成新材料领域具有很大的扩展空间。
