Description

[Technical field]

[0001] The present invention relates to an antifungal agent component containing a metal component, and to an antifungal agent, antifungal material, paint, coating film and molded article containing the same. [Background technology]

[0002] It has long been known that metal ions such as silver, copper, and zinc have antibacterial and antifungal properties, and there are known bactericides and disinfectants to which metal ions have been added in the form of metal salts such as silver nitrate. However, such metal salts have limited uses because they are handled in an aqueous solution state, and there are also safety issues, such as silver nitrate being irritating to mucous membranes. For this reason, it was desirable to use immobilized metal ions with antibacterial and antifungal properties; however, when antibacterial metal ions such as silver ions and copper ions are supported on inorganic carriers such as silica gel, the antibacterial action does not necessarily last long enough, and there are also problems with weather resistance and heat resistance.

[0003] Furthermore, filters that inactivate bacteria, viruses, and molds are known that have a first layer in which zero-valent metals such as platinum and palladium are supported on mesoporous silica, and a second layer that contains a compound with antibacterial and antiviral properties (see Patent Document 1), but it is believed that the antibacterial and antiviral effects are mainly contributed by the second layer. The applicant of the present application had discovered that a catalyst in which a metal component consisting of one or more metal elements of Groups 8 to 12 is supported on a porous carrier is suitable for odor removal, but this technology did not suggest anti-fungal properties (see Patent Document 2).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] <Antifungal agent ingredient> The antifungal component of the present invention comprises a porous carrier carrying a metal component consisting of one or more metal elements of Groups 8 to 12. That is, the antifungal component of the present invention is a composite in which a porous carrier carries a metal component consisting of one or more metal elements of Groups 8 to 12.

[0015] As the porous carrier, any porous carrier capable of supporting a metal component can be used, including any organic carrier such as activated carbon or cellulose carrier, inorganic carrier such as metal oxide carrier or composite oxide carrier, composite carrier which is a composite of these, etc. Among these, porous carriers capable of adsorbing odor components themselves, such as activated carbon, metal oxide carrier or composite oxide carrier, are preferred, and metal oxide carrier or composite oxide carrier are more preferred in terms of the ease of obtaining a porous carrier having the desired particle size and pore size.

[0016] Examples of the metal oxide support include alumina, porous silica, etc. Examples of the composite oxide support include calcium titanate, aluminum silicate, magnesium aluminate, etc. Among these, composite oxides are preferred, zeolites (crystalline aluminosilicates) are more preferred, and MFI type zeolites are particularly preferred, in that they exhibit good antifungal properties. The antifungal component of the present invention has a metal component supported on a porous carrier, and does not directly use metal salts that are easily ionized, making it highly safe, and is particularly safe when the metal component is Pt.

[0017] The average particle size of the porous carrier is usually in the range of 0.01 to 50 μm, preferably 0.03 to 30 μm, and more preferably 0.05 to 20 μm. A porous carrier having such an average particle size is preferable because it can support a sufficient amount of metal components, and the obtained antifungal agent components are easily dispersed in a medium such as a solvent, making it suitable for use in paints and the like.

[0018] Examples of metal elements of Groups 8 to 12 supported on the porous carrier include one or more of Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, and Cd. These metal elements may be supported on the porous carrier in the form of a simple metal, in the form of a metal compound such as an oxide or chloride, or in the form of a composite oxide of two or more metal elements or as an alloy. The antifungal agent component according to the present invention, in which one or more of such metal elements are supported on the porous carrier, has antifungal properties and can suppress the growth of mold for a long period of time.

[0019] The antifungal agent component according to the present invention is not particularly limited, but preferably supports one or more metal elements including Pt (platinum). When a metal element including Pt is supported on a porous carrier, the supported metal species may be only Pt, or may be a combination of Pt and other metal elements of Groups 8 to 12. The ratio of Pt in the total supported metal components (total of Pt and other metals) is preferably 1 mol% or more, more preferably 10 mol% or more. An antifungal agent component in which a metal component consisting of a metal element including Pt is supported on a porous carrier is preferable because it exhibits excellent antifungal properties, the antifungal properties are sustained for a long period of time, and it also has excellent antibacterial and antiviral properties.

[0020] The antifungal agent component according to the present invention may be a commercially available product or may be prepared as long as one or more metal elements of Groups 8 to 12 are supported on a porous carrier. A known method may be appropriately adopted as a method for preparing the antifungal agent component, and for example, a method may be adopted in which a porous carrier is impregnated with an aqueous solution in which a compound containing a metal element is dissolved, and the porous carrier is dried and fired as necessary.

This solution was poured into a 200 cc eggplant-shaped flask, and then 2.0 g of MFI-type zeolite (H-ZSM-5, Tosoh Corporation HSZ 822HOA, silica / alumina ratio (SiO2 / Al2O3 ratio (mol / mol)): 23, average particle size: 5 μm) was poured in to impregnate the zeolite with the Pt compound solution so that the Pt / zeolite was 1%. Next, the flask was attached to an evaporator device, and water was evaporated at 80 ° C under vacuum, and the remaining powder was collected. The collected powder was heated to 200 ° C at 5 ° C / min under 100% H2 flow, and hydrogen reduction was performed for 2 hours to obtain a Pt / zeolite catalyst. The obtained Pt / zeolite catalyst was crushed with a Super Jet Mill (SJ-500, manufactured by Nisshin Engineering) to prepare an antifungal agent component (A-1) in which 1% Pt was supported on zeolite and the average particle size was 2 μm.
