Description

一种造纸用抗菌材料的制备方法
技术领域
本发明涉及一种抗菌剂的制备方法，尤其是一种造纸用抗菌剂得制备方法。
背景技术
与人频繁或密切接触的纸张需要有抗菌作用,如纸巾、纸内裤、卫生巾、证券纸等生活用纸或特种纸。与纺织工业类似,生活用纸及特种纸大多采用天然纤维或合成纤维。天然纤维较易受到微生物损害。这是由于天然纤维易吸湿,在适宜的温湿度条件下,其大分子结构易被所沾染的微生物所分泌的酶水解而释放出营养物质,从而使微生物获得更多的营养而大量繁殖,最终造成纸张霉变。
CN102587210B 公开了一种以油茶果壳制备造纸用抗菌剂的制备方法。其特征在于：将10重量份油茶果壳颗粒加入到25～30重量份戊二醛水溶液中，搅拌加入350～400重量份浓盐酸，在60～75℃下反应4h；加入0.5～5重量份银、锌或铜金属化合物固体，溶解后继续搅拌4～12小时；过滤，洗涤滤渣至中性，将滤渣加入5重量份的碱液或还原剂中，在40～80℃下搅拌反应0.5～3h；过滤，洗涤滤渣至中性，滤渣于40～80℃下干燥得油茶果壳基造纸抗菌剂。
CN102605676B 公开一种利用多酚生物质为载体制备造纸抗菌剂的方法，属于抗菌材料技术领域。首先将多酚生物质颗粒，加入到含交联剂的水溶液中，加入浓盐酸，在80℃下搅拌反应1～1.5h；过滤、洗涤滤渣后将滤渣加入到含氧化剂的水溶液中，在60～100℃下搅拌反应1～3h；再过滤、洗涤滤渣，将滤渣加入到含金属化合物的水溶液中，继续搅拌4～12h；再一次过滤、洗涤滤渣，将滤渣于40～80℃下干燥至恒重，即得多酚生物质基造纸抗菌剂。
现有的造纸用抗菌材料，与纸浆的相容性不好，在纸浆中分布有梳有密，抗菌效果不强，有的还会影响纸张产品的外观和性质。
发明内容
针对现有技术的不足，本发明提供了一种造纸用抗菌材料的制备方法。其制备方法通过以下步骤实现：
按重量份计，在反应釜中加入Q高流速琼脂糖微球，羟丙基纤维素，(2-羟乙基)甲基十四烷基氯代季铵盐，柠檬酸，咪唑并[1,2-A]吡啶-3-基-乙酸，水，脂肪醇聚氧乙烯醚硫酸铵，二(2,2,6,6-四甲基-3,5-庚二酮酸根)钙，升温至80-95℃，在硫酸铜的催化下反应6-12h，反应结束后除去硫酸铜，水洗，干燥，即得到造纸用抗菌材料。
所述的羟丙基纤维素，其质量用量为Q高流速琼脂糖微球的30-50%。
所述的(2-羟乙基)甲基十四烷基氯代季铵盐，其质量用量为Q高流速琼脂糖微球的3-7%。
所述的柠檬酸，其质量用量为Q高流速琼脂糖微球的2-5%。
所述的水，其质量用量为Q高流速琼脂糖微球的90-150%。
所述的咪唑并[1,2-A]吡啶-3-基-乙酸，其质量用量为Q高流速琼脂糖微球的0.1-0.5%。
所述的脂肪醇聚氧乙烯醚硫酸铵，其质量用量为Q高流速琼脂糖微球的0.5-2%。
所述的二(2,2,6,6-四甲基-3,5-庚二酮酸根)钙，其质量用量为Q高流速琼脂糖微球的0.1-0.5%。
所述的Q高流速琼脂糖微球，羟丙基纤维素，(2-羟乙基)甲基十四烷基氯代季铵盐，柠檬酸，咪唑并[1,2-A]吡啶-3-基-乙酸，水，脂肪醇聚氧乙烯醚硫酸铵，二(2,2,6,6-四甲基-3,5-庚二酮酸根)钙均为市售产品。

本发明所生产的造纸用抗菌材料，易于在纸浆中分散，对所生产出的纸产品外观性能的影响小；有效抗菌成分稳定存在，抗菌效果稳定持久。
