Description

一种生活用纸加工中使用的制浆助剂
技术领域
本发明属于造纸技术领域，具体涉及一种生活用纸加工中使用的制浆助剂。
背景技术
纸是我们日常生活中最常用的物品，无论读书、看报，或是写字、作画，都得和纸接触。在工业、农业和国防工业生产中，也离不开纸。今天，如果没有纸，那简直是不可想像的。纸在交流思想、传播文化、发展科学技术和生产方面，是一种强有力的工具和材料。回顾历史，这种重要物质就是我国古代劳动人民发明的。造纸术和指南针、火药、印刷术并称为我国古代科学技术的四大发明，是我国人民对世界科学文化发展所作出的卓越贡献。
生活用纸主要供人们生活日常卫生之用，所以在纸业同行用语通常叫生活用纸，是人民生活中不可或缺的纸种之一。它的形状有单张四方型的，这种叫方巾纸或面巾纸，也有卷成磙筒形状的，这种叫卷纸。它们通常由棉浆、木浆、草浆、废纸浆制造，质量好的卫生纸都是由原生木浆制成，它跟一般纸的制造流程差不多，只是要求制造成极薄极脆弱，这样的目的是当遇到水就会烂掉，达到环保的目的。
造纸工艺的关键在于制浆步骤，纸浆的好换关系到生活用纸的物理化学性能，而制浆步骤中生活用纸加工中使用的制浆助剂的使用十分重要。
发明内容
本发明的目的是针对现有的问题，提供了一种生活用纸加工中使用的制浆助剂，既能够提高得浆率，又能够显著的提高纸的品质。
本发明是通过以下技术方案实现的：
一种生活用纸加工中使用的制浆助剂，按照重量份计由以下成分组成：蒸煮助剂30-35份、消泡剂3.5-4.5份、柔化剂2.5-3.5份、防腐剂2.0-2.5份、抗菌剂1.5-2.0份，其中所述蒸煮助剂的制备方法包括以下步骤：
（1）按照质量百分比计准备以下原料：2-羟基蒽醌占10-12%、亚硫酸钠占4.5-5.5%、三聚磷酸钠占3.5-4.0%、氨基磺酸钠占2.0-3.0%、二亚硫酸钠占1.3-1.5%、硅酸钠占1.0-1.2%、羧甲基纤维素钠占0.4-0.6%、乙醇占15-20%、剩余为水；
（2）将2-羟基蒽醌与水混合，在200-300转/分钟搅拌下，依次添加羧甲基纤维素钠、氨基磺酸钠、三聚磷酸钠，持续搅拌40-50分钟，搅拌结束后加热至60-70℃，分3次将亚硫酸钠和二亚硫酸钠添加到加热溶液中，搅拌溶解；
（3）将硅酸钠加入到乙醇溶液中，在40-50℃下固化2-3小时，置于230-240℃下煅烧10-12小时，将产物添加到步骤（3）中的的溶液中，在100-110℃下加热回流1-2小时，得到产物进行洗涤干燥即可。
作为对上述方案的进一步描述，所述消泡剂按照质量百分比计含有以下成分：松节油占20-30%、二元醇占15-20%、三乙胺占10-15%、月桂酸占5-10%、剩余为硅油。
作为对上述方案的进一步描述，所述防腐剂按照质量百分比计含有以下成分：亚甲基硫氰酸酯占30-35%、二硫代氰基甲酸占20-25%、壳聚糖占15-20%、剩余为硝基丙烷。
作为对上述方案的进一步描述，所述抗菌剂的制备方法为：将硝酸银、硫酸铜、氯化锌粉料研磨至200-240目，加入3-4倍体积的水，在600-700转/分钟加搅拌2-3小时，然后加入质量分数占混合搅拌体系15-20%的沸石粉料，继续搅拌1-2小时，过滤干燥即得。
本发明相比现有技术具有以下优点：为了解决现有生活用纸在制浆加工中的助剂选择不合理问题，本发明提供了一种生活用纸加工中使用的制浆助剂，包含了蒸煮助剂、消泡剂、柔化剂、防腐剂和抗菌剂，加工得到的蒸煮助剂，通过参与脱除木素的反应，增加反应的选择性，夺取蒸煮液中的氧，防止蒸煮罐中的空气在高温和强碱性介质中对纤维的损伤，抑制纤维素的降解，与其它助剂作用，具有很强的螯合能力、分散、增容能力，降低表面张力，提高纸张的白度和均一性，使用本发明的制浆助剂，能够降低蒸煮工艺条件，加快蒸煮速度，既能够提高得浆率，又能够显著的提高纸的品质。
