一种抗菌持久型负离子熔喷非织造布墙纸基纸及其制作方法
技术领域
本发明涉及造纸技术领域，尤其涉及一种抗菌持久型负离子熔喷非织造布墙纸基纸及其制作方法。
背景技术
墙纸，是以纸、非织造布或织造布为基材，加上装饰涂层，广泛用于一些墙面或壁面的装饰。虽然墙纸对建筑的装饰作用并不是必不可少的，但是它已经是营造室内风格、氛围和色彩的重要手段。尤其是以非织造布（无纺布）为基材的墙纸，无论从产品性能还是环保要求上备受人们的青睐。
非织造布墙纸是用天然纤维与合成纤维的混合物来制备的，也有人称它们为长纤维纸，是可以擦洗、可以呼吸的。它消除了气塞现象，能防止发霉，也可以用于厨房和卫生间。该类墙纸是当今市场上最受使用者亲睐和环境友好的产品，具有尺寸稳定性好、装裱方便、抗撕扯等优点。尽管该类墙纸价格稍高于普通墙纸，但未来的消费主体是80后、90后，他们的消费观不同于以往的消费者，更加注重品质、健康，中国经济的增速也完全能够提供支撑，因此中高档的非织造布墙纸更具市场潜力。而随着人们的保健意识的增强，新型环保健康型墙纸愈发收到青睐，尤其是近年来，随着研究人员的探索，发现电气石具有产生负离子、辐射远红外线、抗菌、除臭等功能。因而开发一种添加电气石的能释放负离子的非织造布墙纸迫在眉睫！
《聚丙烯负离子熔喷非织造布的制备与性能研究》一文将不同比例的负离子母粒与聚丙烯切片共混，制备了聚丙烯负离子熔喷非织造布，并研究了负离子母粒含量对非织造布性能的影响。结果表明：随着负离子母粒含量的增加，熔喷非织造布的厚度、面密度和抗静电性能变化不大，透气性和力学性能下降， 抗紫外性能提高。
文中通过添加负离子母粒后降低了透气性和力学性能，制得的非织造布用作墙纸基纸存在易积尘积垢、透气性差、易发霉、遇水即湿、隔音效果差、功能单一等缺陷，因此，本发明改进现有生产工艺和配方，添加纳米二氧化硅加以改性以提高透气性，并配伍其他有效添加剂制备出功能多样的负离子熔喷非织造布墙纸基纸。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种抗菌持久型负离子熔喷非织造布墙纸基纸及其制作方法。

（2）将玉米蛋白粉研磨过100目筛网，喷洒浓度为1-2mol/L的盐酸溶液搅拌混匀，于60-80℃恒温水浴中连续磁力搅拌2-3小时，洗涤至中性真空干燥，加入乙二胺、橙子皮精油在55-75℃下超声研磨1-3小时，得改性玉米蛋白粉；
（3）将木质锯末、荞麦壳搅拌混匀，加水打成浆，加适量质量浓度为1-2%的氢氧化钠水溶液蒸煮5-8小时，保持温度加入步骤（2）物料研磨30-40分钟，冷却用流水漂洗干净，烘干；
（4）将等规聚丙烯加热至熔融状态，加入步骤（1）、步骤（3）物料及其它剩余成分搅拌混匀，通过喷嘴喷丝，出料。
本发明的优点是：本发明将纳米二氧化硅有机改性后复合到电气石粉中，活化改性后添加到原料中，可提高纤维平均细度，纤网结构稀疏，平均孔径增加，透气性变大；同时以改性玉米蛋白粉作为粘接剂，既起到纤维间的粘结作用又可作为植物纤维改善了非织造布的断裂伸长率和抗拉伸性能，再将其与纤维素浆反应，形成致密的三维网状结构，具有较强的隔水性能，利用本发明制得的非织造布墙纸基纸抗静电、抗紫外线性能优、抗菌性持久、物理性能高，用于制作壁纸的适应性强，该种工艺方法无污染、无排放，操作简单，是一种最环保的新型室内装饰材。
