no. 1 Embodiment approach ）

[0043] figure 1 It is an enlarged schematic diagram of a part of the cross section of the antiviral aluminum member 100 according to the first embodiment of the present invention. The aluminum component 100 forms an anodic oxide film 2 on the surface portion of the aluminum component 100 by anodizing aluminum or aluminum alloy. The anodized film 2 is so-called porous alumina, and a large number of micropores 3 having openings are formed on the surface. The metal layer 1 of raw aluminum or raw aluminum alloy that is not anodized is located on the side close to the bottom of the micropore 3 (the side opposite to the surface of the aluminum member 100 having the opening). In this embodiment of the present invention, as figure 1 As shown, a deposit 4 containing an antiviral inorganic compound is deposited in the micropores 3 of the anodic oxide film 2 and fills the micropores 3. For ease of understanding, figure 1 A view showing that the micropore 3 is completely filled with the d...

[0055] Next, refer to figure 2 The antiviral aluminum member 200 according to the second embodiment of the present invention will be described in detail.

[0056] figure 2 It is an enlarged schematic diagram of a part of the cross section of the antiviral aluminum member 200 according to the second embodiment of the present invention. As in the first embodiment, on the surface of the metal layer 1 of aluminum or aluminum alloy, an anodic oxide film 2 with micropores 3 formed by anodic oxidation is formed, and a deposit 4 containing an antiviral inorganic compound is deposited and filled in Micropore 3. Furthermore, a surface film 10 composed of inorganic fine particles 5 and a resin binder 6 composed of an antiviral inorganic compound is formed on the surface of the anodic oxide film 2.

[0057] As the resin adhesive 6, a known adhesive can be used. Specific examples of resin binders may include: polyester resin, amino resin, epoxy resin, polyurethane resin, acrylic resin, wate...

no. 3 Embodiment approach ）

[0068] Next, refer to image 3 The antiviral aluminum member 300 according to the third embodiment of the present invention will be described in detail.

[0069] image 3 It is an enlarged schematic diagram of a part of the cross section of the antiviral aluminum member 300 according to the third embodiment of the present invention. In the third embodiment, a surface film 30 is formed on the surface of the anodic oxide film 2 having micropores 3. The micropores 3 are deposited and filled with a deposit 4 containing an antiviral inorganic compound. The anodic oxide film is similar to the first embodiment. The same way. The surface film 30 contains inorganic particles 5 composed of an antiviral inorganic compound, functional particles 7 for imparting functions other than antiviral properties, and a binder 8 composed of a silane compound. In a specific use environment, for example, a well-known hard coating agent can be added to further improve the strength of the surface film 30. ...

Abstract

The present invention provides an anti-virus aluminum member capable of minimizing secondary infection by deactivating viruses in a short period of time even when viruses adhere thereto, regardless of whether a viral envelope is present, and useful for application in door knobs, handrails, air-conditioner fins or the like. An anti-virus aluminum member capable of deactivating viruses that adhere thereto is characterized in that an anti-virus inorganic compound is present in the pores of an anodized membrane provided with multiple pores and obtained by anodizing aluminum or an aluminum alloy.

Description

Technical field [0001] The invention relates to an antiviral aluminum component that adsorbs viruses and inactivates them in a short time, and has a porous anodic oxide film formed by anodic oxidation. Background technique [0002] In recent years, there have been reports of deaths caused by infections such as SARS (Severe Acute Respiratory Syndrome), norovirus and avian influenza virus. Especially in 2009, due to advanced transportation and virus mutations, the world was facing an "infection outbreak" crisis in which virus infections spread across the world, and serious injuries caused by viruses such as foot-and-mouth disease occurred. Therefore, urgent countermeasures are required. In response to such a situation, the development of vaccine-based antiviral agents is accelerating. But vaccines are specific, so they can only prevent infection with specific viruses. In addition, norovirus is known as a virus that causes acute non-bacterial gastroenteritis. It is the pathogen o...
