Embodiment Construction

[0010]The following describes a silver-plated structure 100 according to an embodiment of the present invention with reference to the drawings.

[0011]First, a configuration of the silver-plated structure 100 will be described with reference to FIG. 1.

[0012]The silver-plated structure 100 is formed on a surface of a base material 1. The base material 1 is made of metal, such as ferrous metal and an aluminum alloy. The silver-plated structure 100 includes a pretreatment layer 10, a resin paint film layer 20, and a silver plating layer 30. The pretreatment layer 10 is formed by washing the surface of the base material 1 with a pretreatment agent. The resin paint film layer 20 is formed on a surface of the pretreatment layer 10. The silver plating layer 30 is formed on a surface of the resin paint film layer 20.

[0013]In general, in a case where the silver plating layer 30 is formed directly on the metallic base material 1, it is difficult to achieve sufficient durability, e.g., adhesive ...

Abstract

A silver-plated structure formed on a surface of a metallic base material includes: a pretreatment layer formed by washing the surface of the base material with a pretreatment agent; a resin paint film layer formed on a surface of the pretreatment layer; and a silver plating layer formed on a surface of the resin paint film layer. The silver plating layer includes: a silver film formed by a silver mirror reaction; an undercoat film that causes the silver film to adhere to the surface of the resin paint film layer; and a topcoat film that protects a surface of the silver film.

Description

TECHNICAL FIELD[0001]The present invention relates to a silver-plated structure in which a silver plating layer is formed on a surface of a base material.BACKGROUND ART[0002]Conventionally, a silver-plated structure is known in which a silver plating layer is formed on a surface of a base material.[0003]JP 2002-256454A discloses a silver-plated structure that is silver plated by forming a basecoat layer, a silver plating layer, and a topcoat layer on a surface of a base material made by injection molding of resin, such as acrylonitrile butadiene styrene (ABS) and polycarbonate (PC).SUMMARY OF INVENTION[0004]In general, silver plating is applied to a resin base material. However, in a case where silver plating is applied to a metallic base material, it is difficult to achieve sufficient durability in practical use.[0005]The present invention aims to improve the durability of a silver plating layer formed on a surface of a metallic base material.[0006]According to one aspect of the pr...
