Description

一种纸箱包装用耐水环保纸板的制备方法
技术领域
本发明涉及化工技术领域，尤其涉及一种纸箱包装用耐水环保纸板的制备方法。
背景技术
纳米硫酸钡是一种新型的无机材料，它既具有普通硫酸钡的特点，又具有新的特殊功能，纳米硫酸钡颗粒，由于具有表面效应、量子隧道效应、尺寸效应等重要的纳米结构特性，使得它的各种物理化学特性与普通材料的性能大有不同，作为一种新颖的高功能性的无机填充材料，它在聚合物复合材料、医学、陶瓷、油墨、涂料、造纸等诸多领域的应用前景都较为广阔。
近年消费增量最大的纸种是箱纸板、白纸板和瓦楞原纸，三大纸种的总和占全国纸和纸板总产量和总消费量的比重已经超过55％。纸和纸板包装制品一直占包装工业材料50％以上，纸制品以良好的环保性能、循环利用的优势，将随包装业的不断发展占据更多的产业市场，包装纸板也将在造纸行业中占据更大的份额。目前采用传统工艺，用木浆、废纸浆等制造的可用于各行业的平板型纸板产品，其密度较大，如果用其作为填层、包装材料，会存在密度大的问题，同时浪费木浆资源，不环保。
张晗在《聚乙烯-硫酸钡纳米复合材料的制备和表征》一文中利用乙二胺四乙酸二钠（EDTA）络合法一步沉淀制备纳米硫酸钡溶液，制备出纳米硫酸钡，并用硬脂酸对硫酸钡表面进行表面有机修饰，脂肪酸盐分子或离子通过长碳链之间的相互排次作用形成表面胶团，因而减小了硫酸钡粒子之间的相互作用，从而改善了硫酸钡颗粒的稳定性，但由于纳米级硫酸钡颗粒很小，其分散性差，常常发生团聚。
发明内容
本发明目的就是为了弥补已有技术的缺陷，解决纳米硫酸钡产品分散差、常常发生团聚的问题，提供一种具有良好强度、柔韧性和耐水性的纸箱包装用耐水环保纸板的制备方法。
本发明是通过以下技术方案实现的：
一种纸箱包装用耐水环保纸板的制备方法，包括以下步骤：
（1）用2-5重量份聚氨基葡糖加入100-150重量份稀冰醋酸溶液中，超声分散30-40分钟后，加入0.5-1重量份过硫酸钠搅拌10-20分钟混合均匀，加入20-30重量份纳米硫酸钡混合均匀后，调节pH值10-12，加入0.1-0.5重量份醚化剂后进行密封后置于微波化学反应器中，设置微波功率为240-280W反应1-10分钟，取出后将体系pH值调节到7-8，过滤干燥6-12小时后，通过研磨机研磨成粉状，得改性纳米硫酸钡；
（2）将40-60重量份经过去杂、过滤处理的木质纤维浆料与植物纤维浆料在打浆机中混合均匀，向混合浆料中加入40-50重量份氧化淀粉溶液，混合均匀，加入0.02-0.1重量份淀粉酶搅拌2-4小时；然后加入步骤（1）所得改性纳米硫酸钡得到浆状混合物；
（3）将步骤（2）所得浆状混合物加入0.1-0.3重量份三聚氰胺混合均匀后加热45-55℃反应1-12小时，得到纸板浆料，待用；
（4）将步骤（3）得到的的纸板浆料输入到纸板成型机上加工，进行脱水成型，之后进行2-3次干燥，直至使纸板的含水量为5-10%，放置12-24小时后打磨，裁切成型既得纸箱包装用耐水环保纸板。
所述调节pH是使用氢氧化钠溶液与盐酸溶液。
所述醚化剂为氯乙醇、氯乙酸、氯乙酸钠中的一种或几种。
所述氧化淀粉溶液的制备方法：先将40-60重量份淀粉、0.5-1重量份氢氧化钠、1-2重量份双氧水和150-200重量份水共同加入容器中60-90℃反应2-4小时，冷却后得氧化淀粉溶液
所述的双氧水质量分数为20-30%。
本发明的优点是：
本发明先配置聚氨基葡糖的稀冰醋酸溶液，加入过硫酸钠反应一段时间之后，接着加入纳米硫酸钡继续反应后加入0.1-0.5重量份醚化剂，过滤干燥即得改性纳米硫酸钡，将纤维浆料混合均匀后打浆，加入氧化淀粉溶液与淀粉酶反应，之后加入改性纳米硫酸钡制成浆状混合物，再加入三聚氰胺进行混合反应得到纸板浆料，经纸板成型机加工脱水干燥成型，聚氨基葡糖经过硫酸钠进行氧化改性后进行醚化反应，使得聚氨基葡糖接上醚化取代基，之后醚化氧化后的聚氨基葡糖通过电荷作用包覆纳米硫酸钡得改性纳米硫酸钡，产物具有疏水的特性，填充制备的纸板具备耐水性，氧化淀粉经过生物酶进行降解后，粘度增加，三聚氰胺作为交联剂加入，使得体系中进行交联，形成稳定的体系，能提高纸板的均匀性和致密性，本发明的制备工艺简单，易于操作，反应所需微波功率低，能耗低，能有效降低成本、节约原料，制备出的纸板可以以氧化淀粉为碳基进行降解，为生物可分解的环保材料。
