Description

一种缓释香型装饰纸的抗菌超疏水整理方法
技术领域
本发明属于装饰纸领域，具体涉及一种缓释香型装饰纸的抗菌超疏水整理方法。
背景技术
在我国，装饰原纸只有四十多年的生产历史，还属于新型产业。随着人们对装修风格要求日益多样化，就需要不断提高装饰原纸的性能，以满足后期加工的要求。但是市场现有装饰原纸存在抗菌疏水性能差的缺陷，并且不能够同时具备缓释香型的性能，所以如何得到一种缓释香型抗菌疏水性能优的装饰纸就显得非常重要。
在本发明中，香精微胶囊化是利用天然或合成的高分子材料对香精进行包裹，既可以避免香精直接受光、热的影响而引起氧化变质，又可以避免香精中有效成分的挥发，有效控制香味物质的释放，提高香味的稳定性。
同时，艾蒿油是提取自菊科植物艾蒿干燥叶的一种天然抗菌物质，具有抗菌谱广、抗菌活性强等优点，但艾蒿油味道强烈，存在有效成分不稳定、贮藏不易等缺点，限制了其应用。使用微胶囊技术可提高艾蒿油的稳定性，扩大其应用范围。利用微胶囊技术将一些抗菌耐久性差、抗菌谱不够广的抗菌剂或抗菌性物质包覆起来制成微胶囊抗菌剂，可改善抗菌剂的加工性能，扩大其应用范围，而后整理技术和微胶囊技术的结合可赋予装饰纸更好的抗菌效果。
发明内容
本发明的目的是针对现有的问题，提供了一种缓释香型装饰纸的抗菌超疏水整理方法，依照该方法整理的装饰纸具有优异的缓释香型、抗菌性能和超疏水性能。
本发明是通过以下技术方案实现的：
一种缓释香型装饰纸的抗菌超疏水整理方法，包括如下步骤，下述原料按重量份计：
（1）装饰原纸的抄造工艺：
将60-75份漂白针叶木浆与40-50份漂白阔叶木浆在水中浸泡3-4h，用打浆机疏解20-30min后，开始打浆，在浆料中加入60-76份钛白粉-高岭土复合悬浮液、2-2.5份湿强剂和0.06-0.08份助留剂，用标准纸页成型器抄片后，真空干燥、平衡水分得装饰原纸；
采用机械化学法制备了钛白粉-高岭土复合悬浮液，钛白粉包覆高岭土不是简单的物理吸附，而是发生了化学反应，钛白粉与高岭土之间有化学键Si-O-Ti和Al-O-Ti的形成，晶型结构发生了变化，包覆效果良好，可以满足装饰原纸对强度、透气度、吸收性以及光学性能等的要求；
（2）装饰原纸的缓释香型抗菌整理工艺：
将（1）中所得装饰原纸浸渍于50-60份缓释香型抗菌微胶囊溶液中，浸渍1-2min后取出，自然干燥得缓释香型抗菌整理的装饰纸；
以三聚磷酸钠为交联剂，以柠檬香精、艾蒿油为囊芯，以壳聚糖为壁材，制备了缓释香型抗菌微胶囊溶液，并采用浸渍法对装饰原纸进行缓释香型抗菌整理，缓释效果好；可赋予装饰原纸良好的抗菌性能，并且通过嗅觉我们可以发现经过浸渍缓释香型抗菌微胶囊溶液的装饰纸香味浓郁，留香时间长；
（3）超疏水涂料的喷涂工艺：
将2-3份疏水化改性的纤维素纳米颗粒、0.6-0.7份甲基三甲氧基硅烷和2-3份水放于密闭反应器中，在20-30℃下反应10-20min后，加入17-18份四氢呋喃中超声1-2h得超疏水涂料，用喷枪将其均匀喷涂在（2）中整理所得装饰纸上，在100-110℃烘箱中固化2-3h，得到缓释香型抗菌超疏水装饰纸；
用十八胺对纤维素纳米颗粒进行了疏水化改性，通过反应十八胺成功接入纤维素纳米颗粒表面，改性后纤维素纳米颗粒的液体接触角增大；再用甲基三甲氧基硅烷对疏水化改性的纤维素纳米颗粒进行硅烷化改性，甲基三甲氧基硅烷与纤维素纳米颗粒羟基发生水解缩合反应，实现化学改性，制得超疏水涂料，喷涂到缓释香型抗菌整理的装饰纸上，加热固化得到缓释香型抗菌超疏水装饰纸；
进一步的，步骤（1）中钛白粉-高岭土复合悬浮液的制备：将0.09-0.11份分散剂六偏磷酸钠加水溶解，加入15-19份高岭土、15-19份钛白粉分散25-35min后，保持研磨浓度为45-55%，再研磨包覆30-40min，得到钛白粉-高岭土复合悬浮液。
进一步的，步骤（1）中打浆度为30-35°SR，湿强剂为PAE，助留剂为CPAM，抄造定量为80-90g/m2。
进一步的，步骤（2）中缓释香型抗菌微胶囊溶液的制备：将1-2份壳聚糖溶于体积分数为2%的稀醋酸溶液，得质量浓度为2-3g/L的壳聚糖醋酸溶液；将0.1-0.2份交联剂三聚磷酸钠1:5溶于水中，加入3-4份柠檬香精、2-4份艾蒿油和1-2份乳化剂吐温20，在40-45℃油浴中高速搅拌20-30min后，再滴加到壳聚糖醋酸溶液中，继续恒温搅拌反应30-50min得缓释香型抗菌微胶囊溶液。
进一步的，步骤（3）中纤维素纳米颗粒的疏水化改性方法：向1-2份纤维素纳米颗粒中1:10加入水配成悬浮液，将0.8-1.9份十八胺1:10溶解在乙醇中，再与悬浮液混合，调节pH为7-8，在60-65℃下搅拌反应3-4h后，用乙醇洗涤3-5次，得到疏水化改性的纤维素纳米颗粒。
本发明相比现有技术具有以下优点：
（1）采用机械化学法制备了钛白粉-高岭土复合悬浮液，钛白粉包覆高岭土不是简单的物理吸附，而是发生了化学反应，钛白粉与高岭土之间有化学键Si-O-Ti和Al-O-Ti的形成，晶型结构发生了变化，包覆效果良好，可以满足装饰原纸对强度、透气度、吸收性以及光学性能等的要求。
（2）以三聚磷酸钠为交联剂，以柠檬香精、艾蒿油为囊芯，以壳聚糖为壁材，制备了缓释香型抗菌微胶囊溶液，并采用浸渍法对装饰原纸进行缓释香型抗菌整理，缓释效果好；可赋予装饰原纸良好的抗菌性能，并且通过嗅觉我们可以发现经过浸渍缓释香型抗菌微胶囊溶液的装饰纸香味浓郁，留香时间长。
（3）用十八胺对纤维素纳米颗粒进行了疏水化改性，通过反应十八胺成功接入纤维素纳米颗粒表面，改性后纤维素纳米颗粒的液体接触角增大；再用甲基三甲氧基硅烷对疏水化改性的纤维素纳米颗粒进行硅烷化改性，甲基三甲氧基硅烷与纤维素纳米颗粒羟基发生水解缩合反应，实现化学改性，制得超疏水涂料，喷涂到缓释香型抗菌整理的装饰纸上，加热固化得到缓释香型抗菌超疏水装饰纸。
