JPH11199407A - Antimicrobial metal formed product - Google Patents

Abstract

PROBLEM TO BE SOLVED: To increase investing effects by unevenly distributing an antimicrobial metal or its salt on the specific part of a metal formed product. SOLUTION: This antimicrobial metal-formed product is produced by adhering an antimicrobial metal or its compound onto the specific part of a surface of a metal formed product by paste, etc., and penetrating the antimicrobial metal or its compound to the ground metal by heating or adhering the antimicrobial metal or its compound onto the specific part of a mold surface for molding the metal products by paste, then casting the ground metal to impart antimicrobial properties onto the specific part of the metal molded product.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to imparting antibacterial and antifungal properties to a metal molded product.

[0002]

2. Description of the Related Art In the case of imparting antibacterial properties to a metal molded article, conventionally, an antibacterial metal such as silver, copper, zinc or the like, or an antibacterial metal such as silver, copper, zinc or a compound thereof is used. ,
The metal had to be mixed when the metal of the object was in a molten state.

[0003] However, in plating, silver, copper, and zinc are applied to the entire surface of a metal molded product, and it is not a completely different object from the ingot. It is as if it is a molded product of silver, copper, and zinc.

[0004] In addition, when the metal of the target metal molding is mixed at a time when the metal is in a molten state, a difference in specific gravity between the metal and an antibacterial metal such as silver, copper, zinc or the like or a compound thereof is remarkable. When it is large or when it is difficult to alloy, it was inconveniently ubiquitous and could not be expected to be present at the target site.

[0005] As a countermeasure, this technique has no practical use unless it is deliberately ubiquitous at a target site to improve the investment effect.

[0006]

DISCLOSURE OF THE INVENTION The present invention is intended to deliberately disperse an antibacterial metal such as silver, copper, zinc or the like or a compound thereof to a specific portion of a metal molded product without impairing the properties of the metal. And improve the investment effect.

[0007]

SUMMARY OF THE INVENTION According to the present invention, in order to intentionally and ubiquitously occupy a specific portion of a metal molded product, a specific portion of the metal slab after molding is used instead of mixing into a molten metal. This is to adhere, heat, and infiltrate, or to cast molten metal after attaching to a specific portion of the inner surface of the mold before molding.

[0008]

Example 1 An antibacterial metal such as silver, copper, zinc or the like or a compound thereof is adhered to a specific portion of a metal molded product to which antibacterial and antifungal properties are desired to be imparted, using a glue or the like, and then heated. , Silver, copper,
An antibacterial metal such as zinc or a compound thereof is made to permeate a surface of a specific portion of a metal molded product.

[0009]

Embodiment 2 An antibacterial metal such as silver, copper, zinc or the like is applied to a specific portion of a casting surface of a mold used when casting a metal molded product, where antibacterial and antifungal properties are desired to be imparted, depending on a paste or the like. The compound is deposited, and then the molten metal is cast to provide antibacterial and antifungal properties at specific sites.

[0010]

According to the present invention, silver,
When an antibacterial metal such as copper or zinc or a compound thereof is mixed, the metal is uniformly dispersed throughout the metal molding, ubiquitous at an inconvenient site, or the antibacterial and antifungal property of the metal molding It is extremely difficult to concentrate ubiquitously on a specific portion to which the user wants to apply the information, and the investment effect is extremely small. According to the present invention, it can be ubiquitous only on the surface of a specific portion of a metal molded product, so that a large investment effect can be expected without impairing the properties of the metal.
