CZ2007355A3 - Multilayer decorative compound glass - Google Patents

Abstract

The invention solves the decoration of multilayer glued glass by inserting decorative material between the glass and the foil prior to the thermal bonding of two or more layers of glass using a certain number of sheets. Using the proven technologies used in manufacturing safety glasses, the original glass properties are retained. The advantage of the invention is the wide variability of the use of different glasses, foils and decorative materials.

Description

Technical field

The invention relates to the formation of decorations from textiles and other materials in multilayer glued glass.

BACKGROUND OF THE INVENTION

At present, multilayer glued glasses are used clear or colored in the mass.

Another possibility of surface decoration of glued glasses is the use of colored foils glued from the outside, or these foils are decorated. This method is not practical with regard to maintenance, short life and UV protection.

There are also known cases of decorating laminated sheet glass, where an ornament print paper is inserted between two glasses. This paper is coated on both sides with an adhesive layer.

Prior art methods of forming a decorative coating on glass prior to bonding or molding are technologically complex and costly. In all the mentioned cases, the small variability of the decor is disadvantageous, especially in its use in the field of architectural design of interiors and exteriors.

Therefore, new methods are sought which make it possible to create a relatively inexpensive and easy manner of a wide selection of decorations corresponding to the demanding requirements of architects, reflecting the materials used in the space. Such solutions require, for example, exterior glass walls, exhibition areas, security barriers, glass staircases, entrance doors, lighting fixtures, furniture, etc.

SUMMARY OF THE INVENTION

The disadvantages of the prior art are solved by multilayer decorative glass, which consists in inserting a decorative material between the glass and the foils before thermally bonding two or more layers of glass using a certain number of films.

For greater variability in the application of the invention, the multilayer decorative glass may be shaped.

The advantage of the method according to the invention is the possibility to choose one reflective layer of glass and thus minimize the effect of sunlight on the decorative material used.

Another advantage of the method according to the invention is the wide possibility of using different types of glasses and materials for decoration of glued glass with different price range and required functions.

Depending on the required thickness of the laminated glass, the desired number of glass layers is optionally thermally bonded by means of further foils.

From an economic point of view, the advantage of the process according to the invention is the relatively low cost with simultaneous multipurpose use.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, one embodiment of the method according to the invention is shown.

The decorative laminated glass of Figures 1 and 2 consists of two layers 1 and 4 of clear, transparent glass panes inside of which clear polyvinyl butyral foil 2 is sealed and the lace 3 is used as a decorative material.

AND

In the exemplary embodiment, the two-layer glued glass decoration technology consists of the following four steps:

1) a clear polyvinyl butyral foil is placed on a transparent clear sheet glass.

2) a decorative material, in this case a fine lace, is deposited on said foil.

3) an additional layer of transparent clear sheet glass is placed on the blank thus prepared.

4) at the required temperature and pressure, the two glasses are joined together with the panel to form an object according to the invention.

Overview of the drawings

The proposed solution of the invention is illustrated in the accompanying drawing, in which Fig. 2 shows a cross-section of an exemplary decorative laminated glass and Fig. 1 shows a perspective view of a decorated glass.

Method of industrial applicability of the invention

The proposed solution of the invention can be widely used in various industries, especially in the glass and construction industries.

The invention has the following advantages:

(1) using existing laminated glass technology;

2) allows the thermoforming of glass,

3) uses a wide assortment of produced glass sheets and foils,

4) uses a very wide range of decorative materials to reflect the building elements and materials used,

(5) significantly improves with regard to the placement of the decorative material between at least two glasses,. maintenance of realized buildings, 6) the use of a safety foil results in a standard safety glass with a décor whose use is very wide and popular in the construction industry; * 7) allows a wide range of product modifications such as cutting, grinding, polishing etc.
