Description

一种箱板纸高效增强剂及其制备方法
技术领域
本发明涉及化工领域，涉及箱板纸添加剂领域，尤其涉及一种箱板纸高效增强剂及其制备方法。
背景技术
箱板纸又称牛皮纸、牛卡纸，是纸箱用纸的主要纸种之一。国产箱板纸分为优等品、一等品、合格品三个等级。牛皮纸的质地必须坚韧，耐破度、环压强度和撕裂度要高，此外还要具有较高的抗水性。由于工艺及用料的不同，总的来说，大部分进口牛皮卡纸的质量要好于国产牛皮纸，尤其以美国产牛卡的质量为最佳。检测项目有:定量、厚度、紧度、耐破度、耐破指数、环压强度、横向环压指数、裂断长、撕裂度、施胶度、水分、横幅定量差、横向耐折度等等。箱板纸的用途，主要是与瓦楞纸芯粘合后制成瓦楞纸箱，用来包装家用电器、日用百货、针棉织物、文化用品、中西成药的外包装等。箱箱板纸所用的原料有硫酸盐木浆、废麻浆、棉杆浆、废纸浆、稻麦草浆。对箱板的要求是应有一定的抗压强度、坚韧耐破、抗撕裂、纸面平整，不许有浆疙瘩、节子和凹凸不平的外观纸病。随着人们的生活质量提高，造纸行业迅速发展。截至2014年箱板纸产量可达2200万吨/年，拥有3300亿元的市场。然而箱板纸作为包装用纸，也对其成纸的性能提出了要求。传统的施胶方法，性价比低而且对环境有污染，给后续的水处理带来了一定的难度。本发明为绿色环保的助剂，能有效的提高箱板纸各项物理指标。
发明内容
本发明针对现有技术不足，提供一种箱板纸高效增强剂及其制备方法。为了达到上述目的，本发明的技术方案为：
一种箱板纸高效增强剂，按重量成分包括以下物质：
所述杀菌剂为次氯酸盐、二氧化氯、氯胺中的任意一种，所述消泡剂为有机硅消泡剂、聚醚消泡剂中的任意一种。
一种制备所述箱板纸高效增强剂的方法，包括以下步骤：
(1)将聚丙烯酰胺加入反应釜内，加入去离子水，搅拌至混合均匀；
(2)加入水溶性聚醚，升温至60-70℃；
(3)加入聚乙烯醇，升温至110-125℃；
(4)加入消泡剂和杀菌剂，搅拌至混合均匀，得到箱箱板纸高效增强剂。
作为优选，所述步骤(1)中搅拌时间为0.8-1.0h。
与现有技术相比，本发明的优点和积极效果在于，
聚乙烯醇加入纸浆中能渗透到纤维表面和内部，经过加热处理后，树脂与相邻的纤维之间的羧基、羟基、氨基发生脱水缩合反应，形成共价键，从而降低了纸张被水浸湿后纤维与纤维之间的滑动倾向，使纸张产生一定的湿强。本发明提供的高效增强剂具有绿色环保，能有效的提高箱板纸的耐破耐折性能。本产品可有效的减少淀粉和硫酸铝的使用，甚至完全取代淀粉。而且本产品为绿色环保的化学品，无呛人气味，无污染，同时也间接的减少了后续工段的成本。
