Abstract

PURPOSE:To weld glass and another glass having given shapes each other, or to form letter patterns, etc. on the surface of glass, by arranging a glass molded article on the surface of another glass molded article by adhesion, forming letter patterns on them, covering them with a heat-resistant molding member, sintering them under heating. CONSTITUTION:The glass molded article 1b is arranged on the surface of another glass molded article 1a by adhesion with putting the adhesive 2 (e.g., starch, epoxy-based resin adhesive, etc.) between them, they are covered with the heat-resistant molding material 3 (e.g., one obtained by blending gypsum with water, solidifying the blend), and sintered at about 750 deg.C for about 3hr, to decorate and to mold a glass product. The starting glass molded article may be prepared by artificial blowing or mechanical blowing, a glass material of glass mass or glass particles are packed into a heat-resistant gypsum mold consisting of an easily fragile heat-resistant molding material, heated directly in the gypsum mold, and a glass molded article is released from the gypsum mold and used preferably.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention allows glass of a desired shape to be easily welded to each other or to create desired characters on the surface of a glass product.

This invention relates to a decorative molding method for glass products that can form patterns and the like.

Conventionally, when manufacturing glass by artificial blowing, there is a technique called "appliqué" in which a small lump pre-shaped into a desired shape is welded to the surface of the glass using an air-blowing method called "appliqué".
This process was impossible to achieve without requiring a high level of skill, as it involved blowing and heating glass molten at a relatively high temperature.

In view of the above, the present invention has a relatively low temperature (700 to 800°C).
Further, the present invention provides a method for decorating and molding glass products, which not only allows the so-called "application" to be achieved without requiring any skill, but also allows desired characters, patterns, etc. to be freely applied to the glass surface.

The present invention is applicable to any glass product made by artificial blowing or machine blowing. However, in order to prepare the starting glass products in advance without requiring a skilled person, it is possible to fill a mold made of a heat-resistant material that is easy to crush with glass ingots such as glass lumps and glass particles, and then heat the mold while still in the mold. A so-called sintering method may also be used to obtain glass in a desired shape. .

The present invention uses a viscous organic material such as starch glue on the surface of these glass molded products to adhere to other glass molded products, or applies letters, patterns, etc. on the surface of the glass molded products, and When the mold has solidified to a certain extent, the glass molded product is covered with a heat-resistant mold, such as heat-resistant plaster diluted with water, and this is heated and sintered to fuse the glass and create desired letters, patterns, etc. The present invention provides a novel decorative molding method for molded glass products.

The present invention will be described in more detail 111 by way of examples with reference to the drawings.

1 to 5 relate to the first embodiment, and in the figures, 1a indicates the first embodiment.
FIG. 1 is a sectional view of the glass molded article.

1b shows the second glass molded product, and FIGS. 2 and 3 are its plan view and sectional view, respectively.

Reference numeral 2 denotes a viscous organic adhesive (adhesive), and although a starchy glue is used in the embodiment of the present invention, an epoxy resin adhesive or glue may also be used.

3 is a heat-resistant mold, and in this embodiment, heat-resistant gypsum that has been solidified by dissolving it in water is used.

FIG. 3, 1c is a glass product obtained by adhering and arranging both molded products 1a and 1b with adhesive, covering with mold material 3, and sintering at 750° C. for 3 hours.

The starting glass molded product was artificially blown as described in 611,
Alternatively, mechanical blowing may be used, but in the present invention,
A glass molded product is used, which is filled with glass material such as glass lumps and glass grains into a heat-resistant plaster mold made of a heat-resistant mold that is easy to crush, heated with a stone-Ilr mold, and peeled off from a stone-r\ mold. There is.

Furthermore, the glass molded products 1a and 1b have similar coefficients of linear expansion. Figure 1,
Either mold the radius around the glass molded products 1a and lb shown in FIG. 2 to be constant so that there is no gap between them, or
Power) Ruiha.

Process it to make it sweet.

If the glass molded product 1a in Figure 1 is polished too much and has a concave surface, you can fill it with glue and glue 2 to make the glass product 1.
Hail there is a concave surface on c.

Desired characters are written on the connecting parts of each glass molded product 1a and lb or on the surface of the glass molded product 1a.

If you apply a pattern, etc., the glass product 1c will have the same character as that.
It has a pattern 7r.

Figures 6 to 13 relate to the second embodiment of the present invention (numerals have the same meanings as above), and as shown in Figures 8 and 9, the letter a is painted on a plate-shaped molded product 1a with an adhesive 2 such as glue. When glue 2 has hardened to a certain culm, heat-resistant plaster is applied by diluting it in water and the shape of 1'JJI 2 is not damaged at all, and it hardens and becomes heat-resistant mold material 3. Soyoru.

This is placed in a furnace and heated, and the direction in which the mold is held takes into consideration the direction in which the glass flows.

Letters, patterns, etc. are applied using glue or the like, and if there are many areas, the glue is fired and glass flows into the area to form the pattern. Therefore, if it is necessary to equalize the thickness and height of glass products, use a heat-resistant molded material that can be replenished with glass pieces 1d whose coefficient of linear expansion is similar to that of glass molded product 1a, as shown in Figure 11. do.

Although not shown in FIG. 4, a technique that does not change the height of the product is to place it in a mold that allows glass with a similar coefficient of linear expansion to be heated and poured from the top, as in FIG. 11.

When a glue or the like is placed between the glass molded products 1a and lbO, heat-resistant plaster or the like does not penetrate into the joint, and the glue is baked when heated, and the glass molded products 1a and lb are completely welded. By peeling off the stone mold after heating in this manner, an "aplique" can be made or desired letters, patterns, etc. can be formed.

This example was held at 750°C for 3 hours, which is a relatively low temperature, and even an amateur can make any desired product without requiring any skill, making it extremely useful as a /111 decorative molding method for glass products. obtain.
