Description
技术领域
本发明涉及制备全茶麸生物灭菌全降解功能母料塑料的方法,属生物化工范围。
背景技术
淀粉降解塑料自问世以来得到了迅速发展,但都只具备安全性、降解性、茶麸功能母料相对于一般淀粉塑料具有独特的灭菌灭虫功能,茶麸塑料母料即可单独用于制造热塑型热固型塑料制品,还可作为生物灭菌灭虫塑料制品中的添加剂使用,因此具有独特的应用价值。
发明内容
本发明的目的正是为了利用每年产生的大量天然茶麸全利用,克服茶麸行业现行基本只提取茶皂素,浪费茶麸剩余的80%物质缺点,利用茶麸内含有茶皂素、淀粉、纤维素、蛋白等制备独特的全降解茶麸塑料功能母料,同单一淀粉基塑料母料颗粒相比其优势在于:由于茶皂素具有高双亲性,灭菌性,因而具有塑化性能优良,独特的灭菌灭虫功能、完全降解,成本低。
本发明的主要技术方案是 :一种用茶麸制造功能塑料母料的方法,其特征是,包括以下步骤 :
(1) 将茶麸粉碎至 100-2000 目加入高速搅拌罐中,喷入油脂,茶麸与油脂比例为85~99:15~1在低于100℃下混合搅拌 5~ 30min 后, 得到塑化茶麸;
(2)将塑化茶麸与树脂搅拌均匀后螺感杆挤出成型即可,塑化茶麸与树脂比例为50~90: 50~10。
本发明所述的茶麸是指山茶科果仁压榨油后的剩余物。
本发明所述的茶麸包含未改性茶麸、离子改性茶麸、糊化茶麸、氧化茶麸。
本发明所述的塑料树脂是指低分子聚烯烃蜡、石蜡、EVA蜡、松香树脂、涤纶树脂、聚乙烯、聚乙烯醇、EVA树脂、PU、SBS、POE、聚丙烯、聚氯乙烯、ABS树脂、尼龙。
