Definitions
- the present invention relates to a silver plating structure in which a silver plating layer is formed on the surface of a substrate.
- JP2002-256454A silver plating by a base coat layer, a silver plating layer, and a top coat layer is formed on the surface of a base material formed by injection molding of a resin such as ABS (Acrylonitrile Butadiene Styrene) or PC (Polycarbonate).
- ABS Acrylonitrile Butadiene Styrene
- PC Polycarbonate
- silver plating is generally formed on a resin base material, and even if silver plating is formed on a metal base material, it is difficult to obtain practically sufficient durability.
- An object of the present invention is to improve the durability of a silver plating layer formed on the surface of a metal substrate.
- the silver-plated structure formed on the surface of the metal substrate includes a pretreatment layer formed by washing the surface of the substrate with a pretreatment agent, A resin coating layer formed on the surface of the treatment layer; and a silver plating layer formed on the surface of the resin coating layer.
- the silver plating layer has a silver film formed by a silver mirror reaction, an undercoat film that adheres the silver film to the surface of the resin coating layer, and a topcoat film that protects the surface of the silver film. .
- FIG. 1 is a cross-sectional view of a silver-plated structure according to an embodiment of the present invention.
- FIG. 2 is a diagram illustrating a procedure for forming a pretreatment layer.
- FIG. 3 is a diagram illustrating a procedure for forming a resin coating layer.
- the silver plating structure 100 is formed on the surface of the substrate 1.
- the substrate 1 is a metal such as an iron-based metal or an aluminum alloy.
- the silver plating structure 100 includes a pretreatment layer 10 formed by washing the surface of the substrate 1 with a pretreatment agent, a resin coating layer 20 formed on the surface of the pretreatment layer 10, and a resin coating. And a silver plating layer 30 formed on the surface of the film layer 20.
- the silver-plated layer 30 is formed via the resin coating layer 20 after the pre-treatment layer 10 made of the pre-treatment agent is formed on the metal substrate 1.
- the pretreatment layer 10 is formed by zinc phosphate coating treatment, iron phosphate coating treatment, or non-chromium treatment depending on the material of the substrate 1.
- the pretreatment layer 10 improves the adhesion of the resin coating layer 20 to the surface of the substrate 1.
- the pretreatment layer 10 is preferably a coating formed by zinc phosphate coating treatment when the substrate 1 is an iron-based metal.
- a pretreatment agent composed mainly of phosphate ions and zinc ions is used.
- the pretreatment layer 10 is preferably a film formed by non-chromium treatment.
- a pretreatment agent containing zirconium and cobalt is used as an alternative to hexavalent chromium.
- the resin coating layer 20 improves the adhesion of the silver plating layer 30 to the pretreatment layer 10. In addition, the resin coating layer 20 smoothes out micro unevenness present on the surface of the substrate 1 to reduce the flatness tolerance.
- the resin coating layer 20 is formed by electrodeposition coating, solvent coating, or powder coating depending on the material and shape of the substrate 1.
- the resin coating layer 20 is desirably an electrodeposition coating containing an epoxy resin and a pigment when the substrate 1 is an iron-based metal.
- the pigment includes a pigment having rust preventive power.
- the rust prevention power of the base material 1 which is an iron-type metal improves by forming the resin coating film layer 20.
- the kind of pigment used for an electrodeposition coating film is suitably selected according to the objective from carbon black, a rust preventive pigment, a moisture resistant pigment, etc.
- the electrodeposition coating film may be formed of particles having a particle size of 20 ⁇ m or less.
- the particles forming the electrodeposition coating film have a particle size of 10 ⁇ m or less even if the particle size is small.
- the resin coating layer 20 is a finely dispersed electrodeposition coating formed by particles having a particle size of 5 ⁇ m or less. Therefore, the flatness tolerance of the surface of the resin coating layer 20 can be reduced by the amount that the particle size of the particles is small. Therefore, when this electrodeposition coating film is formed, the surface becomes flat, so that the silver plating layer 30 is easily adhered and a beautiful silver mirror can be obtained.
- the resin coating layer 20 is preferably an acrylic resin coating film that is applied using a solvent.
- the rust-preventing power is not strongly required, so that the resin coating layer 20 can be a coating film of acrylic resin.
- This coating film is formed of a multi-layer finish coating material mainly composed of an acrylic emulsion resin, and an acrylic silicon coating material is used as the top coating agent. Even when an acrylic resin coating film is formed, the surface is flat as in the case of forming an electrodeposition coating film, so that the silver plating layer 30 is easily adhered and a clean silver mirror is obtained. Can do.
