Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing decorative glass, and more particularly to a method for manufacturing glass provided with a concave pattern and a colored pattern.

Conventionally, engraving a concave pattern on a glass surface is the last step in manufacturing plate glass, and as shown in the first diagram, the unhardened glass 1 is passed between a mold roll 2 and a pressure roll 3 to perform embossing. This has been carried out by a method of forming a concave pattern 4.

However, this method (1) requires a large amount of equipment for manufacturing; (2) it is not profitable unless a single pattern is produced in large quantities (the more patterns there are, the more mold rolls are required). (3) There are drawbacks such as the inability to simultaneously manufacture various types of patterned glass, and there is a demand for the development of a method for engraving concave patterns that can be performed using simple equipment. It has been.

On the other hand, painting on the glass surface is done by printing a pattern using silk screen printing method and then firing it at 200 to 300 degrees Celsius, but it is not possible to apply color to the concave pattern area. I couldn't do it.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for manufacturing glass with a concave pattern and a colored pattern, which can be carried out using simple equipment.

That is, the gist of the present invention is to provide a hardened resin layer that adheres well to the glass on a glass surface, then adhere a decorative material on the hardening resin, and then apply the resin on the decorative material. The resin is impregnated into the decorative material and a surface coating layer is formed, while a resin composition non-adhesive to the resin is placed on a support non-adhesive to the resin of the surface coating layer. A molding sheet is created by forming a convex pattern corresponding to the concave pattern to be formed on the surface coating layer, and the molding sheet is applied to the surface of the surface coating layer and heated and pressurized or left at room temperature. After that, the method for producing decorative glass is characterized in that the molding sheet is peeled off from the surface of the surface coating layer.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

First, the glass is completely degreased, and if necessary, the surface is treated with silicon compound treatment (silane treatment) and chromium compound treatment agent (silane treatment) to increase affinity with resin and strengthen adhesive strength.
After using a surface treatment agent such as borane treatment)
As shown in the second figure, a layer 5 of a curable resin that adheres well to the glass 1 is provided on the glass 1 surface.

Next, a decorative material 7 with a printed layer 6 of an arbitrary pattern is pasted on the cured resin 5, and then a resin 8 is applied on the decorative material 7 as shown in the fourth figure. is impregnated between the seven layers of the decorative material, and a surface coating layer 9 is formed. On the other hand, the fifth
As shown in the figure, a resin composition that is non-adhesive to the resin 8 should be recessed on the surface coating layer 9 on a support 10 that is non-adhesive to the resin 8 of the surface coating layer 9. A molding sheet 12 is created by forming a convex pattern 11 corresponding to the concave pattern.

Next, as shown in FIG. 6, a sheet 12 for marking and forming is applied to the surface of the surface coating layer 9, and after being heated and pressed or left at room temperature, it is peeled off from the surface of the surface coating layer 9 as shown in FIG. In this way, a decorative glass 14 is obtained in which the surface coating layer 9 is provided with a concave pattern 13 and a printed layer 6 with an arbitrary pattern is provided below the surface coating layer 9.

In the above-mentioned present invention, as the hardened resin 5 which has good adhesion to the glass 1, for example, thermosetting resin such as polyester resin, melamine resin, diallelphthalate resin, epoxy resin, silicone resin, polyurethane resin, etc. Alternatively, thermoplastic resins such as initial condensates of these, polyvinyl butyral, acrylic resins, modified resins of saponified ethylene-vinyl acetate copolymers, and water glass can be used. As a method of applying the above-mentioned resin on the top, one or two of the above-mentioned resins
Any composition in the form of a solution, emulsion, suspension, or sol containing at least one species can be coated using known coating methods such as brushing, spraying, flow coating, roller coating, dip coating, mirror coating, flow coating, etc. This can be done by coating it on the glass.

Next, in the above-described present invention, when the decorative material 7 and C are required to be transparent, it is necessary to use so-called transparent paper that becomes transparent after being impregnated with resin, and is not opaque. If necessary, so-called titanium paper containing titanium can be used.

The appropriate basis weight of the paper is 20 to 50 V/M2 for transparent paper, and 50 to 1207/M2 for opaque paper, but it is not necessary to use these base papers and there are no restrictions on synthetic paper, art paper, earthen paper, etc. Therefore, the above-mentioned decorative method for paper can be carried out by ordinary printing methods, which may be rolled or sheet-fed, and include multicolor printing of photographs by gravure, offset, and letterpress. Effective.

Also, line drawings using silk screens etc. are extremely effective for abstract patterns. Although mass production is not possible, hand-painting is possible in some cases. In addition, printed sheets such as films can also be used, but it is not necessarily necessary to use sheets with patterns; for example, it is also possible to make use of the texture of non-woven paper, cloth, etc.
You can also strip the wood grain thinly to make the most of the wood's skin. Furthermore, in addition to these sheet-like objects, various powders and granular objects can be mixed or used alone to create various patterns by changing the particle size, particle size distribution state, color, shape, density, etc. You can also take it out. Next, in the present invention, as the resin 8 applied on the decorative material, it is preferable to use a resin that is rich in various fastness notes such as weather resistance, wear resistance, and resistance to wear and tear. For example, , vinyl resin, acrylic resin, polyester resin, melamine resin, phenol resin, epoxy resin, polyurethane resin, etc. can be used.

These resins can be applied in the same manner as the above-mentioned method of applying resins that are highly compatible with glass. Next, in the present invention, the support 8 may be various resin films and sheets such as polyvinyl alcohol, polyester, polyethylene, polypropylene, polyamide, etc., laminates of two or more of these films and sheets, and various papers. It is possible to use materials which have been subjected to mold release treatment, materials obtained by laminating the above-mentioned films and sheets with various types of paper, metal foils, and the like.

Next, in the present invention, the resin composition that does not adhere to the resin 8 of the surface coating layer may include various oils and fats such as linseed oil, soybean oil, synthetic drying oil, rosin copal dammar, hardened rosin, rosin ester, or Natural and processed resins such as polymerized rosin, synthetic resins such as phenolic resin, maleic resin, alkyd resin, petroleum resin, vinyl resin, acrylic thread resin, polyamide resin, epoxy resin, and amino alkyd resin, nitrocellulose, Ink compositions or coating compositions containing cellulose derivatives such as ethyl cellulose, rubber derivatives such as chlorinated rubber and cyclized rubber, other glues, casein, dextrin, zein, etc., or the above resins mixed with a release agent. can be used.

Therefore, the resin composition must be capable of being printed or applied to a support.

Further, in the above-mentioned present invention, as a method for forming the convex pattern 11 on the support 10, known printing methods such as silk screen printing, gravure printing, offset printing, flexo printing, transfer, embossing, hand drawing, etc. can be used. It will be done.

In the present invention, the concave pattern is expressed by the thickness of the convex pattern layer 8, but even if the thickness is thin and there is no unevenness, the surface condition of the support 10 and the surface condition of the convex pattern layer 11 may be different. If used, it is possible to produce a beautiful decorative glass according to the present invention in which the degree of reflection and refraction of light is different between the patterned portion and the non-patterned portion, and a clear concave image with sufficient contrast is formed.

In the present invention described above, after the resin 8 is appropriately poured onto the decorative paper 7, the surface may be smoothed by pressing it with a roller or the like in close contact with the molding sheet [2].

The glass obtained in the above manner not only has an extremely beautiful decorative quality that has never been seen before, but also has a uniform resin layer that prevents it from scattering when broken, making it highly safe. .

In addition, the method according to the present invention is easy to operate up to production, and can be used not only in glass production areas but also in glass consumption areas to create a wide variety of desired concave patterns, and is suitable for small-scale production. It has the advantage of being sufficiently profitable, allowing the production of various types of patterned glass at the same time, and having very few manufacturing restrictions.

Furthermore, according to the method according to the present invention, conventional decorative plywood equipment can be used. Further, according to the method according to the present invention, it is possible to stock a wide variety of molding dies and to produce products according to orders. Therefore, the glass obtained by the method of the present invention as described above can be suitable for various uses, such as partitions, table tops, window windows, cabinet cases, window glasses, cupboards, etc.
Glass doors and other items that use plate glass can be replaced with beautifully decorated items, regardless of whether they are transparent or opaque.

Next, the present invention will be described in more detail with reference to Examples.

Example 1 First, a grain pattern was printed on a vinylon film having a thickness of 25 μm using ink using a polyamide resin as a binder.

Separately, a floral pattern was printed on a 30 Vm2 overlay paper by gravure printing using ink using cellulose acetate resin as a binder.

Next, the surface of a plate glass of about 30 CTIL square and 2~ thick was completely degreased with acetone, and the glass surface was treated with a silane coupling agent.

Next, a mixture of 100 parts of unsaturated polyester resin and 1 part of the hardening agent Permeck is poured onto the glass surface, brought into contact with the printed overlay paper vinylon film, and a rubber roller is applied over the vinylon film to uniformly and uniformly spread the resin surface. Finished smooth, vinylon film, overlay paper, polyester resin, and glass were integrated.After that, leave it at room temperature for about 1 hour, then peel off the vinylon film and polyamide resin layer, and the floral pattern coloring and texture will be revealed. A beautiful decorative glass with irregularities was obtained.

Example 2 First, a polka dot pattern was printed on a 25 μm thick polyester film by silk printing using an ink containing a vinyl chloride resin mixed with a release agent.

Separately, continuous printing of blue with different densities was performed on 55 Vm2 titanium paper using gravure printing using ink using cellulose acetate resin as a binder.

Next about 30? The surface of a square, 2♂-thick plate glass was completely degreased with acetone, and the glass surface was treated with a silane coupling agent.

Next, a mixture of 100 parts of epoxy resin and 32 parts of an amine-based curing agent is poured onto the glass surface, brought into contact with the printed titanium paper and polyester film, and the resin surface is finished uniformly and smoothly using a rubber roller over the polyester film. , integrated polyester, titanium paper, epoxy resin and glass.

Thereafter, after being left at room temperature for about 2 hours, the polyester film and the vinyl chloride ink layer were peeled off to obtain a beautiful decorative glass with concavities and convexities of polka dots in a blue color that varies in intensity continuously.
