An object of the present invention is to provide a method of fixing an antibacterial agent, by which method it is possible to impart articles of a wide range of materials with excellent antibacterial property and good persistence of antibacterial activity. Specifically, the method of fixing an antibacterial agent, comprises the steps of:
subjecting a surface of an article to a surface treatment of providing the surface with oxygen-containing functional groups; and then
subjecting the article to a treatment using an antibacterial agent composition including a silicon-containing compound (a) represented by general formula (1) below.
wherein R1 represents a hydrocarbon group having 6 or more carbon atoms, R2 and R3 represent lower hydrocarbon groups, respectively, which hydrocarbon groups may be the same or different from each other, R4 represents a divalent lower hydrocarbon group, R5, R6 and R7 represent lower alkyl groups or lower alkoxy groups, respectively, which may be the same or different from each other, and X represents a halogen ion or an organic carbonyloxy ion, or alternatively, first treating the article by using the antibacterial agent composition; and then subjecting the article to a 1-10 GHz microwave irradiation treatment in a state where the antibacterial agent composition remains on the surface of the article.
本发明的目的是提供一种固定抗菌剂的方法,通过这种方法可以使各种材料制成的物品具有优异的抗菌性能和良好的抗菌持久性。具体来说,固定抗菌剂的方法包括以下步骤
对物品表面进行表面处理,使其表面具有含氧官能团;然后
使用抗菌剂组合物对物品进行处理,该抗菌剂组合物包括由以下通式 (1) 表示的含硅化合物 (a)。
其中 R1 代表具有 6 个或更多碳原子的烃基;R2 和 R3 分别代表低级烃基,这些烃基可以彼此相同或不同;R4 代表二价低级烃基;R5、R6 和 R7 分别代表低级烷基或低级烷氧基,这些烷基可以彼此相同或不同;X 代表卤素离子或有机羰氧基离子;或者,首先使用抗菌剂组合物处理物品;然后在抗菌剂组合物留在物品表面的状态下对物品进行 1-10 GHz 微波辐照处理。
