Description

一种纸箱用环保型复合粘合剂
技术领域
本发明涉及一种纸箱用环保型复合粘合剂，属于包装技术领域。
背景技术
瓦楞纸箱是常用的包装材料，瓦楞纸箱生产中粘合剂为必不可少的生产材料。所用的粘合剂主要有泡花碱、玉米淀粉胶和聚乙烯醇三种，泡花碱粘合剂因易受潮开胶和碱污已逐步淘汰；玉米淀粉胶粘合剂由于胶液较稀会造成吐楞和倒楞，且成本较高和受潮后易霉变；聚乙烯醇水溶液粘合剂由于粘结力强，因此得到广泛应用，但该粘合剂辊涂性差、成本高，而且同样存在吐楞、倒楞的问题，同样存在不足。
在现有技术中，通过向淀粉胶中添加其他成分来改善其性能，如添加甲醛以提高防腐能力，添加硼砂以提高防霉能力。但此类添加成分往往含有对人体有刺激性或有毒，存在安全隐患，特别是用于对食品、饮品、化妆品的纸质包装，存在不足。
