RU2357871C2 - Method of decorative glass tiles production - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: invention is referred to construction and deals with the production of decorative glass tiles. The glass tiles are applied with heat sublimation transparent lacquer. Image fragments are then applied above the lacquer by thermal transition method. After lacquer self-cooling, a layer of white background paint is applied on the image. As soon as the paint is cured, a reinforcing mat is glued to the same side of glass tiles.

EFFECT: improved technology of decorative glass tiles production and reduced prime cost.

Description

The proposed technology relates to the field of construction, in particular to indoor and outdoor decoration.

Known art stained glass windows made of glass of various colors and textures by fastening them together with lead broaches. (one)

A method of manufacturing stained-glass windows requires artistic skills, since in the process of manufacturing stained-glass windows a sketch is drawn, on which glasses of various colors are then selected.

The manufacturing technology of stained-glass windows requires painstaking manual labor, which results in their high cost.

The disadvantage of stained glass is also the use of an additional light source, since the finished stained glass is fully visible only in the light.

Known art stained glass windows made by the English technology "Regalead". (2)

This technology differs from the traditional one in that multi-colored films and decorative broaches are glued onto the glass, which visually resembles a full-fledged stained-glass window.

A known method of manufacturing a decorative ceramic tile used in construction. (3)

It is referred to as the method of applying underglaze paints to a ceramic or porcelain surface, followed by glazing under the influence of high temperature in a muffle furnace - “decal”. Using the decal method, images are applied to mugs, plates, souvenirs, tombstones, etc.

With high quality products, the disadvantages of this technology are high energy consumption during firing, a large percentage of rejects during production and the high cost of the final product.

A known method of manufacturing tiled tiles. (four)

Tiles are manually painted with special paints and then fired.

This technology for the manufacture of tiles is very similar to the technology "decal" and is morally obsolete.

The method of thermal transfer image transfer (5) to various surfaces (including ceramic tiles) has appeared relatively recently. The principle of this technology is to transfer sublimation ink from a liquid to a gaseous state from a carrier onto a material under the influence of high temperature and pressure. Solid materials should be coated with a thermosublimation varnish, into which ink penetrates during transfer. This technology is mainly used in the manufacture of souvenirs (images on T-shirts, mugs, plates, key chains, etc.). The advantages of this technology in its simplicity and low cost. Disadvantages - in an unreliable, thin layer of protective varnish, which undergoes rapid mechanical wear, in which the image is located.

The objective of the proposed method is to expand the capabilities of design ideas, improve technology and reduce the cost of manufacturing decorative tiles as a finishing material.

The problem is solved through the use of new manufacturing technology, including the use of a computer program, the method of thermal transfer.

The proposed method is illustrated in the drawing, which shows the manufactured decorative fiberglass and the positions indicated:

1 - Glass

2 - Varnish

3 - Picture

4 - Background paint layer

5 - Layer of glue

6 - Reinforcing layer

A method of manufacturing a decorative fiberglass is as follows.

A sheet of glass of the M-1 brand 5 mm thick is cut into small rectangles - tiles. The sizes of the tiles are individual to the sizes of the combined format (in particular, the most common format is 20 × 25 mm). For safety reasons and an aesthetic appearance, the edges of the tiles are ground along the contour. Thermosublimation transparent varnish is applied to one of the sides of the tiles (this side is internal). Using the appropriate program in the computer, select the image and its size. The processed image is “broken” with the help of a program on a scale corresponding to the size and number of tiles used in the finished image, and printed out in a color printer.

Images obtained on paper are transferred to a layer of transparent varnish on the inner side of the tile by thermal transfer in a special thermal press.

After cooling the tiles, a layer of white paint is applied to the side of the varnish with the image for background reflection of the image fragment in a transparent varnish.

Then, after the paint has dried, a reinforcing material is glued to the same side of the tiles for better adhesion to the tile adhesive during its installation (galvanized wire mesh).

The photopanel obtained from the decorative fiberglass obtained by the proposed method is protected from mechanical influences by glass, which is also the basis of the tile, has an aesthetic appearance and allows you to realize a variety of design ideas. The use of new technology can significantly reduce the cost of finished products.

Claims (1)

A method of manufacturing a decorative glass tile, including the method of thermal transfer of the image for decorating glass tiles, characterized in that the thermo-sublimation transparent varnish is applied to the glass tiles, onto which the fragments of the image obtained by computer “splitting” according to the size of the image are applied, after cooling the varnish onto the image a layer of white background paint is applied and after the paint has dried, a reinforcing mesh is glued to the same side of the tiles.
