RU2073655C1 - Method for production of decorative glass - Google Patents

Abstract

FIELD: production of decorative plates and articles of multilayer glass. SUBSTANCE: sheets of glass are packed up in layers. Thus prepared packet is affected by heat treatment. In between glasses more than two pairs of adhesive film and decorative materials are placed to produce volume image. Dried plants or pictures of thin paper sheets or metal foil are used as mentioned above decorative material. EFFECT: improved efficiency.

Description

 The invention relates to the production of glass art products and can be used in the manufacture of decorative tiles, products from laminated glass type triplex.

A known method of manufacturing decorative glass, in which an enamel layer is applied to the glass, dried, placed on a sand layer and heat treated. A clear glass is obtained from above, and an enamel layer from below [1]
A known method of manufacturing a translucent stained glass window, in which a polyvinyl butyral film with a pattern is applied to a sheet of glass, a colored glass cullet is laid according to the pattern and heat treated [2]
Known methods significantly limit the choice of pattern on glass, i.e. images on the glass are one-sided.

The closest is a method of obtaining decorative embossed glass, in which a gas-generating substance, glass chips and heat-treating are placed between the glass sheets [3]
Glass obtained by this method does not have sufficiently good decorative properties that can be obtained using the proposed method.

 The aim of the invention is to obtain glass with good decorative properties, while without complicating the manufacturing technology of such glass.

 The goal is achieved in that when receiving decorative glass by layering sheets of glass and a material that gives the glass decorative properties, between them and subsequent heat treatment as a decorative material take floral material dried plants or patterns of thin sheet materials, while two sheets of glass are placed between the glass sheets or more layers of adhesive film and decorative material are placed between the layers of adhesive film.

The method is as follows. They take two plates of glass, put two adhesive films between the plates, and a dried plant between the adhesive films. The assembly is placed under a press between the heating plates and heat treatment is carried out under a pressure of not more than 0.5 kgf / cm ² .

The heat treatment temperature depends on the composition of the adhesive layer. In particular, when using floristic material, it is recommended to use a polyvinyl butyral film. When using this adhesive film, heat treatment is carried out at a temperature of 75 ± 10 ^o C. At this temperature, gluing sheets of glue, glass, and floristic material retains its color.

 Instead of floristic material, any thin sheet material can be used, for example, patterns cut out of paper or metal foil. In this case, a polyvinyl butyral film may also be used. Plants or patterns can be laid between several layers of films. In this case, a three-dimensional image effect occurs. You can first place a picture, for example, a postcard, on the glue layer on the adhesive layer, and for example, lay dried plants between subsequent layers. In this case, we get a three-dimensional picture with the background.

Decorative glass was made. For this, two plates of glass were taken. An adhesive film was placed on one plate, and dried carrot tops, which had a green color, were placed on it. The tops of carrots have a good decorative appearance, so it can be widely used in the preparation of various compositions. A layer of adhesive film was again placed on the floristic material, on top a second glass plate and a flaky assembly were placed between the heating plates of a 10-ton hydraulic press with a hand pump. The pressing force did not exceed 0.5 kgf / cm ² . The exposure under pressure at a temperature of 75 ^o C was 3-10 minutes

 The result was a clear laminated glass with a sprig of carrot tops, which completely retained its color.

 In another case, a laminated decorative glass with a three-dimensional image was made.

To do this, a polyvinyl butyral film was placed on the lower glass, on which the stalks of carrots, parsley and moss were laid. Then the first layer of plants was covered with a second adhesive polyvinyl butyral film and a number of stems of carrots, parsley and moss were also laid on it. After that, three more pairs of layers of polyvinyl butyral and plant material were laid. After applying the last film of polyvinyl butyral and applying the upper glass, the resulting package was placed between sheets of rubber, tightly fastened around the perimeter and having a vacuum outlet in one place. The bag in a rubber bag was placed in a bath of water heated to 75 ^o C, and connected to a foreline pump. After 10 minutes exposure, the bag was removed from the bag, and it was a decorative two-layer glass, between the layers of which there was an inseparable transparent monolayer, in which at various distances from the glass surface there were plant elements that created a three-dimensional picture imitating the forest.

 Thus, the proposed method allows to obtain highly artistic decorative glass, while the technology for its manufacture is practically not complicated in comparison with the known manufacturing method.

Claims (1)

 A method of producing decorative glass by layer-by-layer laying of sheets of glass and decorating material between them, followed by heat treatment, characterized in that dried plants, or patterns from sheet materials of paper, metal foil, are taken as decorating material, while two or two are placed between the sheets of glass more layers of adhesive film, and decorating material is placed between the layers of adhesive film.
