摘要
多孔建筑涂层由于多孔性的特点对病毒具有吸附作用,从而赋予涂层抗病毒活性,而多孔涂层的抗病毒活性可能受测试中多种因素影响。选用多孔硅藻土制备多孔建筑涂层,以噬菌体MS2和φA039作为非包膜病毒模型测试多孔涂层的抗病毒活性,研究抗病毒测试中病毒储备液种类、病毒悬液滴加量及其浓度对抗病毒测试结果的影响。结果表明,应尽可能选择与稀释液有机组成相同的储备液;涂层表面悬液滴加量应视样品大小而定;涂层表面滴加病毒悬液浓度以1×10^(7) PFU/mL为宜。分析了多孔建筑涂层抗病毒测试中最佳测试条件,提出测试中需要注意的问题,为多孔涂层抗病毒测试和标准制定提供参考。
Porous architectural coatings possess adsorption properties due to their porous nature,thereby imparting antiviral activity to the coatings.Consequently,the antiviral activity of porous coatings may be influenced by various factors during antiviral testing.Porous architectural coatings were prepared using porous diatomite,and the antiviral activity of the coatings was tested using bacteriophage MS2 andφA039 as non-enveloped virus models.The study investigated the effects of virus stock solution types,virus suspension droplet volume,and concentration of the droplet-added virus suspension on the antiviral test results.The results show that the stock solution with the same organic composition as the diluent should be selected as far as possible in the test.The volume of virus suspension droplets added to the coating surface should be determined based on the size of the sample.The optimal concentration of virus suspension was 1×10^(7) PFU/mL.This paper analyzes and puts forward the best conditions and problems needing attention in the antiviral test of porous architectural coating and provides reference for the antiviral testing and standard development of porous coatings.
