Abstract

PURPOSE:To prevent corrosion of an exposed metal film and form a feeling of ground glass, by forming a silver film and backing material on one side of a glass plate, removing part thereof and coating an exposed part of the glass with a transparent resin obtained by blending stable fine powder. CONSTITUTION:A reflecting silver film 7 and copper film 8 are formed on one side of a glass plate 6 and a resin backing material 9 is further formed on the surface of the silver film 7 and copper film 8 to protect the films 7 and 8. Sandblasting is them carried out from the side of the above-mentioned backing material 9 to remove part of the backing material 9, copper film 8 and silver film 7 and expose the glass plate 6. The resultant exposed part is them coated with a protective coating material prepared by blending 100pts.wt. transparent resin, e.g. epoxy based resin, etc., with 5-10pts.wt. chemically stabilized fine powder, e.g. SiO2, CaCO3, etc., to form a resin film 10 having a constant thickness. Thereby corrosion of the metal films 7 and 8 is prevented and the aimed mirror plate.

Furthermore, a spray gun can be used for full-surface coating, and silk screen printing can be applied for patterning and multi-color coating, which is extremely productive compared to sandblasting. It is possible to efficiently perform a sandblasting-like decorative process, and to obtain a transparent color similar to expensive colored glass using transparent glass as a base material.

When a resin film of a protective paint made of a transparent resin mixed with chemically stable fine powder such as 5in2.0aCOz is applied to a certain thickness around the area where part of the backing material and silver film has been removed and its periphery. The sandblasting process prevents corrosion of the exposed metal film, and the light transmitted through the resin film is diffusely reflected or refracted on the finely uneven surface formed by the mixture of fine powder, giving it a frosted glass feel.

In this case, even if the above protective paint is applied thickly at 1001L or more, a sandblast-like surface can be obtained without reducing the light transmittance, and if a small amount of coloring agent is mixed in, it will become colored and semi-transparent, so that it can be seen from the back of the mirror plate. If you apply this paint after sun or doblasting, you will get strong anti-corrosion properties, and you can also finish only the treated areas to look like colored glass.
