Description

The present invention relates to a method for producing a multilayer glass.

Conventionally, dichroic glass in which a thin film is formed on the surface of glass by vacuum-depositing a metal or the like on the surface of plate-shaped glass is widely known.

Dichroic glass having a thin film formed on the surface of the glass can form a film-like pattern on the surface of the glass by partially removing the thin film on the surface by sandblasting (see, for example, Patent Document 1).

Special Table No. 8-502233 Gazette

If the thin film on the surface of the glass is partially removed to form a pattern, the pattern on the surface may peel off from the glass due to wear, etc., and the glass is affected by long-term use and climate. The pattern on the surface of the glass may be discolored or deteriorated.

Therefore, as it is, it is difficult to effectively use it indoors and outdoors as accessories such as necklaces and earrings, decorative items such as emblems, and display items such as signboards and information boards.

Therefore, in the present invention according to claim 1, in the method for producing multilayer glass, glass and a base layer, which are surface layers having higher transparency than the base layer, are laminated with a pattern formed in a film shape sandwiched between them. After that, it was decided to fire the glass to be the base layer and the surface layer.

Further, in the present invention according to claim 2, in the present invention according to claim 1, after forming a film-like pattern on the surface of the glass serving as the base layer, the transparency is higher than that of the glass serving as the base layer. It was decided to laminate the glass to be the surface layer on the surface of the glass to be the base layer, and then to fire the glass to be the base layer and the surface layer.

Further, in the present invention according to claim 3, in the present invention according to claim 1, after forming a film-like pattern on the back surface of glass which is a surface layer having higher transparency than glass which is a base layer, the base is used. It was decided to laminate the glass to be the base layer on the back surface of the glass to be the surface layer, and then to fire the glass to be the base layer and the surface layer.

Further, in the present invention according to claim 4, in the present invention according to claim 3, the base layer is formed of glass paste.

Further, in the present invention according to claim 5, in the present invention according to any one of claims 2 to 4, it is based on the front surface or the back surface of the glass of the intermediate layer having higher transparency than the glass serving as the base layer. After forming a film-like pattern different from the pedestal layer, one or more intermediate layers of glass are laminated between the base pedestal layer glass and the surface layer glass, and then the pedestal is formed. We decided to fire the glass that will be the layer, the intermediate layer, and the surface layer.

Further, in the present invention according to claim 6, in the present invention according to any one of claims 1 to 5, it is decided to use a glass larger than the glass of the other layer as the glass of the surface layer.

That is, in the present invention, in the method for producing multilayer glass, glass and a base layer, which are surface layers having higher transparency than the base layer, are laminated with a film-like pattern sandwiched between them, and then the base layer is formed. And because the glass that becomes the surface layer is to be fired, the glass of the surface layer makes the film-like pattern glossy and makes it look more beautiful, and the film-like pattern formed on the surface of the base layer. Is not affected by wear, long-term use, or the influence of the climate, and can prevent pattern peeling, discoloration, and deterioration. It can be effectively used as a display tool.

In the multilayer glass, after forming a film-like pattern on the surface of the glass to be the base layer, the glass to be a surface layer having higher transparency than the glass to be the base layer is laminated on the surface of the glass to be the base layer. Then, it can be easily produced by firing the glass serving as the base layer and the surface layer.

Further, in the above-mentioned multilayer glass, after forming a film-like pattern on the back surface of the glass as the surface layer having higher transparency than the glass as the base layer, the glass as the base layer is formed on the back surface of the glass as the surface layer. It can be easily produced by laminating and then firing the glass to be the base layer and the surface layer. When the base layer is formed by using a glass paste, it is possible to prevent the invasion of air bubbles and to produce a lightweight multilayer glass having a thin overall thickness.

In particular, after forming a film-like pattern different from that of the base layer on the front surface or the back surface of the glass of the intermediate layer having a higher transparency than the glass serving as the base layer, one or more pieces of the glass to be the intermediate layer are formed. If it is decided to laminate between the glass to be the base layer and the glass to be the surface layer, and then to fire the glass to be the base layer, the intermediate layer and the surface layer, one or more of the base layer and the glass. A variety of three-dimensional patterns can be expressed by a plurality of patterns formed on the glass that is the intermediate layer of the sheets, and the visual design can be improved.

Further, when it is decided to use a glass larger than the glass of another layer as the glass of the surface layer, the glass of the surface layer may be eluted to the periphery of the base layer or the intermediate layer to cover the layers at the time of firing. It is possible to prevent peeling between layers and invasion of dust and moisture into the layers.
