Description

一种防霉、除菌、抗病毒、净化空气多功能型环保壁纸
技术领域
本发明属于壁纸技术领域，具体地，涉及一种防霉、除菌、抗病毒、净化空气多功能型环保壁纸。
背景技术
在现代房屋装修中，人们会选择节能环保性能突出的墙面装饰材料。壁纸以其安装方便、美观大方等优点而被人们广泛应用于室内建筑装饰领域。现有的壁纸产品功能单一，防潮效果较差，容易产生霉变。霉菌在一定的自然条件下大量存在于墙体表层，如黑曲霉、黄曲霉、木霉、球毛壳霉等，诱发呼吸道过敏反应。壁纸在粘贴过程中，存在有机挥发物污染的风险，影响室内环境，危害人类健康。此外，壁纸材料容易粘附和寄生各种细菌和病毒，成为潜在的疾病传播途径。
发明内容
本发明的目的在于提供一种防霉、除菌、抗病毒、净化空气多功能型环保壁纸，壁纸材料中添加复合纳米颗粒作为抗菌防霉抗病毒剂及有机物分解催化剂。该壁纸成本低廉，抗菌、防霉、抗病毒效果好，环境净化能力强，具有很好的实用价值。贵金属纳米颗粒，如银、铜、金、铂、钯等具有很好的防霉、抗菌和抗病毒能力，氧化物半导体纳米颗粒，如二氧化钛、氧化锌、氧化亚铜、氧化铁等具有很好的颗粒物俘获能力和光催化降解污染物能力。将贵金属纳米颗粒和氧化物半导体纳米颗粒以一定的比例同时负载于壁纸上，能够有效地杀灭吸附于壁纸表面的霉菌、细菌、病毒，并降解室内有机污染物，具有良好的环境净化能力。此外，本发明将金属纳米颗粒与半导体纳米颗粒配合使用，有助于提高纳米颗粒的环境稳定性。
本发明的目的可以通过以下技术方案实现：
一种防霉、除菌、抗病毒、净化空气多功能型环保壁纸，由壁纸纸张和复合纳米颗粒添加剂组成，复合纳米颗粒添加剂均匀负载在壁纸纸张上；
其中，复合纳米颗粒添加剂包括纳米金属颗粒和纳米半导体颗粒，纳米金属颗粒可以为纳米银、铜、金、铂、钯的一种或几种；纳米半导体颗粒可以为二氧化钛、氧化锌、氧化亚铜、氧化铁、钒酸铋的一种或几种。
进一步地，所述纳米金属颗粒直径在1-1000纳米范围内；所述纳米半导体颗粒直径在1-1000纳米范围内。
进一步地，所述纳米金属颗粒的直径在1-200纳米。
进一步地，所述纳米半导体颗粒的直径在1-200纳米。
进一步地，所述壁纸纸张与复合纳米颗粒添加剂的比例为：每平方厘米面积的壁纸纸张上负载纳米金属颗粒的质量在0.1微克至100毫克之间，每平方厘米面积的壁纸上负载纳米半导体颗粒的质量在0.1微克至100毫克之间。
本发明的有益效果：
本发明将金属纳米颗粒和半导体纳米颗粒同时负载于壁纸上，利用金属纳米颗粒防霉、除菌、抗病毒，利用半导体纳米颗粒作为光催化剂分解有机污染物。利用金属纳米颗粒与半导体颗粒之间的相互作用提高提高纳米颗粒的环境稳定性。
