SILVER-PLATED STRUCTURE
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.
1 . A silver-plated structure formed on a surface of a metallic base material, the silver-plated structure comprising:
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, wherein
the silver plating layer includes a silver film, an undercoat film, and a topcoat film, the silver film being formed by a silver mirror reaction, the undercoat film causing the silver film to adhere to the surface of the resin paint film layer, and the topcoat film protecting a surface of the silver film.
2 . The silver-plated structure according to claim 1 , wherein
the resin paint film layer is an electrodeposition paint film containing epoxy resin and a pigment.
3 . The silver-plated structure according to claim 2 , wherein
the electrodeposition paint film is formed of particles having a particle diameter of 5 μm or smaller.
4 . The silver-plated structure according to claim 1 , wherein
the base material is made of ferrous metal.
5 . The silver-plated structure according to claim 1 , wherein
the base material is made of an aluminum alloy, and
the resin paint film layer is an acrylic resin paint film painted by using a solvent.
