Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a decorative glass plate whose surface is colored by coating a color material on one or both surfaces of the glass plate and performing a baking treatment.

[0002]

[Prior art]

 In many cases, decorative panels of building walls or pillars have plates made of colored tiles or crystallized glass. In addition, a glass plate cut and colored from sheet glass may be used. However, recently, due to the diversity of interior decoration, designers and owners sometimes apply design decorations with unique colors and shapes to the walls or pillars of relatively small buildings. To meet these demands, it is difficult to respond to the variations in shape and color with conventional colored tiles, glass plates cut out from crystallized glass or flat glass and colored.

[0003]

[Problems to be solved by the invention]

 In the present invention, it is an object of the present invention to provide a glass plate used for the decoration of a building wall or a pillar without limiting the shape and color according to user needs and at a low cost.

[0004]

[Means for Solving the Problems]

 As a result of intensive studies on the above-mentioned problems, the present inventor coated a color material on one surface of a glass plate pressed by a known automatic or manual glass press forming machine, and baked to color the surface. It is a decorative glass plate characterized by the following.

[0005]

[Embodiment of the invention]

 The details of the present invention will be described below. The method for manufacturing a decorative glass plate of the present invention is a known automatic or manual method in which a molten glass lump is supplied into a mold and pressed by a plunger attached to the tip of a cylinder rod operated by air pressure or hydraulic pressure. A glass plate with both surfaces smooth and flat surface properties is formed with a press molding machine. By changing the shape and size of the mold and the plunger, it is possible to form a glass plate having an arbitrary shape and dimensions with both surfaces smooth and flat. The color of the base glass is preferably colorless and transparent, but colored glass may be used. Regarding the dimensions of the glass plate, the thickness is preferably 3 to 20 mm, and if it is 3 mm or less, molding is difficult, and if it is 20 mm or more, the weight of one glass plate is large, or distortion tends to remain after molding or coloring. It is not preferable. The outer dimension is preferably 25 to 250 mm, and if it is less than 25 mm, molding is difficult, and if it is more than 250 mm, warpage may occur after molding or after gradual distortion, which is not preferred.

When a glass plate is formed by forming a convex line engraving on a glass contact surface of a plunger and / or a mold at the time of forming a glass plate, a linear groove shape is formed on the surface of the formed glass plate. . For example, as shown in FIG. 3, when grooves are formed in a grid pattern, it looks like a single tile assembly plate in which small square glass tiles are laminated. The advantage of press molding is that the groove shape can be formed freely, not only in a straight line but also in a curved line.

[0007] Next, the method of coloring the surface of the glass plate is performed by applying a ceramic color, a noble metal paint represented by gold or platinum or a raster paint to a screen printing method, a spray method, a brush coating method, a roller coating method, a stamp method, or the like. Coating the surface of the glass plate using a tampo method, or pasting transfer paper on the surface of the glass plate, and then passing it through a baking furnace and baking it, and coloring the ceramic color by screen printing This is preferable because the method is easy and the cost is low.

The coloring of the surface of the glass plate can be performed on one side or both sides of the glass plate. When the entire surface is colored, the colored side of the glass plate is adhered to the wall or column of the building. This can prevent discoloration and peeling of the colored surface, and is particularly preferable when a noble metal paint or a raster paint having a small adhesive strength to glass is used as the coloring material. If both sides are colored, for example, when used for room partitions or screens, different colors and / or design patterns on both sides of the glass plate will create a different atmosphere space between the inside and outside of the partitions or screens. Is obtained.

The coloring of the glass plate is not limited to the entire surface of the glass plate, but may be partial coloring. In the case of a glass plate with a linear engraving pattern on one side, a smooth and flat surface on the other side without the engraving pattern has an area unit divided by the linear engraving pattern formed on the other side. By coloring the same color and / or a different color according to the position directly below, a mosaic tile-like color glass plate combining individual color glass tiles can be obtained. In this case, it is also possible to color each area unit divided by the linear engraving pattern on the surface side having the linear engraving pattern.

EXAMPLES Example 1 150 g of a glass lump melted at a high temperature is fed into a mold and pressed with a plunger attached to the tip of a hydraulically operated cylinder rod to make it 97 mm square and 6.4 mm thick. A square flat glass plate was formed on both sides of the square. After molding, the glass plate was passed through a lehr to be gradually strained. On the other hand, a screen was made such that a square pattern with a side of 48 mm was printed. Using the screen, yellow, pink, sky blue and gray hot ceramic color inks were screen-printed using a hand printing press so that one surface of the glass plate was divided into four equal parts. The glass plate on which one surface of the glass plate was screen-printed into four equal parts in four colors was passed through a baking furnace, and ceramic color ink was baked on the glass plate. The state of the obtained colored glass plate is shown in FIG.

Example 2 Using the same screen as in Example 1, the surface of the colored glass plate obtained in Example 1 was divided into four equal parts on the uncolored side opposite to the colored side. As a result, yellow-green, red, blue and brown hot ceramic color inks were screen-printed using a manual printing press. The glass plate on which four color screens were printed in four equal parts was passed through a baking furnace, and hot ceramic color ink was baked on the glass plate. The state of the obtained double-sided colored glass plate is shown in FIG.

Example 3 A convex line engraving having a width of 2.5 mm and a height of 2 mm is formed on the glass contact surface side of a mold in three longitudinal and lateral directions at an interval of 24.2 mm from a center line of the line width. 150 g of molten glass at a high temperature is supplied into the metal mold which is applied orthogonally, and press-molded using a plunger attached to the tip of a hydraulically operated cylinder rod to form a 97 mm square, A square glass plate having a thickness of 6.4 mm was formed. After molding, the glass plate was passed through a lehr to be gradually strained. One side surface of the glass plate has a smooth and flat surface texture, and the other side has a width of 2.5 mm and a depth of 2 mm so as to be orthogonal to each other at an interval of 24.2 mm each in a longitudinal direction and a lateral direction. A glass plate with linear groove sculptures was obtained. Its shape is shown in FIG. On the other hand, a screen was made such that a square pattern with a side of 24.2 mm was printed. On the smooth and flat one surface side of the glass plate where the linear groove engraving is not formed using the screen, directly below the area unit defined by the linear engraving pattern formed on the opposite surface side Using a screen printing machine, a screen printing was performed so that yellow, pink, yellow-green, and red hot ceramic color inks were alternately arranged at positions corresponding to the above. The screen-printed glass plate was passed through a baking furnace, and the ceramic color ink was baked on the glass plate. The state of the obtained colored glass plate is shown in FIG. As can be seen from FIG. 4, by forming a linear groove sculpture on the glass plate and coloring the opposite surface, it looks like a mosaic tile-like color glass plate combining individual color tiles.

[0013]

[Effect of the invention]

 As is apparent from the above description, a glass plate can be formed into an arbitrary shape by using a press forming machine, and the surface of the glass plate can be freely colored or patterned by a coloring method such as a screen printing method. Can easily respond to the designer's or owner's request.Because of the post-processing on the glass plate, it can also respond to small lot orders and form linear groove sculptures on the surface. The use of a colored glass plate has the effect of greatly reducing the construction time compared to the conventional construction where individual color tiles are combined on site. As described above, it is extremely possible to solve the problems of the conventional method and to provide a glass plate with a new design at a low cost, thereby contributing to the development of industry.
