JPS58115039A - Manufacture of decorated glass article - Google Patents

Abstract

PURPOSE:To manufacture a decorated glass article having protected glass surface, easily, at a low cost, by coating a formed glass with a coloring agent, drying and fixing the coating layer, and removing a part of the coloring agent in the form of desired pattern. CONSTITUTION:A glass 1 having a normal composition is formed to an article having desired shape by forming process. The surface of the glass 1 is coated with a coloring agent 2 such as epoxy resin having a color different from the glass 1, and the agent is dried at normal temperature or with heat or baked and fixed to the glass 1. A part of the coloring agent 2 and if necessary the corresponding part of the surface of the glass 1 is cut and removed in a desired pattern to expose the surface of the glass 1 and obtain the objective decorated glass aritcle. If necessary, the product is coated wholly with a clear protecting film 3 such as acrylic resin film to attain the further protection of the glass 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing decorative glass products, and includes the production of extremely decorative (rich glass products) such as so-called colored glass products.
The present invention also relates to 13 & method of producing extremely elegant decorative glass products in the style of craft glass, in which the inner glass material is sufficiently protected against external impacts.
.

Conventionally, glass panels with a thin surface layer of colored glass, that is, colored glass, are manufactured by first molding a thin outer body of colored glass with a base, and then molding it from the inside again with a different colored glass. It was formed so that a double white color was obtained between the color of the outer fabric and that of the inner body. Then, the outer body part is cut in a predetermined pattern and other surface treatments are applied (therefore, the polished part is exposed as the fabric surface of the body, and the other part remains as the fabric surface of the outer body, so the craft glass It is intended to be a decorative glassware with a strong tone.

However, when molding colored glass in this way, advanced technology is required, and since each piece is handmade, it is quite difficult to produce large quantities of the same type of glass.

Therefore, the present invention was created in view of the current situation, and is a glass that is rich in decorative properties similar to conventional colored glass.
8 can be produced inexpensively and in large quantities for the first time without any troublesome effort, and the glass material can be sufficiently protected to stabilize the product.

That is, the present invention includes a molding process of shaping a glass material into a predetermined shape, a molded glass material surface 1; Or, it consists of a step of making mrit by fading, and a cutting step of removing a part of the coloring agent and the surface of the glass material in a predetermined shape, and furthermore, a transparent protection is applied to the whole of the cut bond. and a test step for testing the membrane.

Hereinafter, specific details of the present invention will be explained with reference to the drawings.

First, a molding step is carried out in which a glass material 1 having the same component ratio as conventional glass material is molded into a predetermined shape by a required means.

The shape of the glass material 1 at this time may be one that follows the final shape of the finished product, and usually has a container shape.

Next, a coloring agent 2 having a color different from that of the glass material 1 is applied to the surface of the molded glass material 1, such as a synthetic resin coloring agent such as epoxy resin, acrylic resin, or melamine resin, or an inorganic coloring agent such as ceramic or luster. The coloring agent 2 is applied to the surface of the glass vertical member 1 by drying at room temperature or by heating or baking to fix the coloring agent 2 to the surface of the glass vertical member 1.

At this point, the inorganic power stabilizer 2 forms a stronger film than synthetic resin-based or even organic-based ones, so it has superior strength and is extremely resistant to external impact. It is valid.

Furthermore, after coating and fixing, a cutting step is performed to cut out a part of the coloring agent 2 and the surface of the glass material in a predetermined pattern. This so-called cutting involves cutting off the colorant 2 and also a part of the glass material 1 to expose the surface of the glass material 1 (see FIG. 2).

The shape is not limited to the basic shapes such as Azanoha, Kagome, Hexagonal Kame, Kiku Kagome, Diamond, Kumonosu, etc., but it can be done in any shape, and the cut IirM can be used as Kakuyama, Kamaboko, etc. He is free. Of course, as shown in the drawings, it can be cut not only on the negative side but also on both sides, or on each side, and furthermore, it can be cut in various shapes.

Although the bales that have undergone this cutting process are shipped as products, a test process may be carried out in order to protect the glass material 1. In other words, this coating process is
A transparent protective film 3 is applied to the entire cutting machine (see Figure 3). For example, a transparent inorganic material such as epoxy resin, acrylic S++, transparent synthetic resin such as melamine resin, or ceramic is coated and dried. It is something that makes you By smoothing the surface after cutting using this test process, gloss and transparency can be obtained.

However, some of the coloring agent 2 coated and fixed on the surface of the glass material 1 molded into a predetermined shape was further removed.
Since the surface of the glass material 1 is cut out in a predetermined pattern, the color of the glass material 1 and the color of the colorant 2 are mixed, and at the same time, the color of the glass material 1 is removed as a predetermined pattern. Extremely elegant decoration - demonstrating Noh.

Moreover, it is sufficient that the glass material 1 is obtained by the conventional and well-known Ili method, and the troublesome double-forming method that has been used as a manufacturing method for laminated glass can be avoided. It is not necessary and can be produced in large size and at low cost.

Not only that, the glass material 1 itself is energized by the coloring agent 2, which protects the glass material 1 and cushions it from external shocks and vibrations. It is extremely useful.

6- Next, specific examples of the present invention will be given to help in understanding the invention.

Example 1゜Glasumi A material 1, which is a transparent glass bottle sold as a cosmetics product, has acrylic resin paint 1, coloring agent 2, and G 1 on its surface.
Spray LC red (trade name of Easy Chemical Industry Co., Ltd.) with a spray gun to a thickness of about 5 μm. Then 170
After baking at ℃ for 30 minutes, cutting was performed using a grindstone. It should be noted that GL(, Red') was able to color the glass element 1141 with a thickness of 1 μU degree.

Negative - @2゜The entire product after the cut process according to Example 1? GLC-B-1 Clear (trade name of Easy Chemical Industry Co., Ltd.), which is a acrylic resin-based paint, is sprayed with a spray gun and baked at 170°C for 30 minutes on 11F to maintain transparency! 1113.
