BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing colored remelted glass such as glossy surface plate materials used for building materials and the like, and to glass materials thereof.

0002

[Prior Art] For example, glass materials such as glass particles or frit particles that have been melted into particles in advance are introduced into a predetermined mold and reheated to be used as interior and exterior building materials with a glass-like luster on the surface. It is known that the material is melted and formed into a predetermined plate shape. This remelted glass can be used as a wall material after surface polishing if necessary, or as a non-slip floor material after being polished to a lower level.

However, in conventional remelted glass of this type, the glass particles used as the glass material are crushed and classified ordinary transparent plate glass or frit for recrystallized glass, and colored frit is expensive. For various reasons, most of them are generally colorless and transparent. Note that recrystallized glass becomes emulsified by recrystallization. Furthermore, even if you disregard costs and obtain re-melted glass by using colored glass particles or colored frit, the colored molten glass will simply be colored glass with no depth, as if it had been painted. Therefore, it has not been possible to obtain a glass material with a beautiful surface similar to that of natural stone.

Furthermore, attempts have been made to color the glass grains or frit grains by blending them with pigments or metal oxides; Due to the non-uniformity of the glass material, there are parts that are not integrated with the glass material.Therefore, moisture may penetrate into these non-integrated parts, and the glass material may become brittle, making it difficult to obtain sufficient strength.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to propose a method for producing colored remelted glass and a remelted glass material therefor, which solves all of the above problems. In particular, the present invention proposes a method for producing colored glass having a beautiful appearance and having a pattern of various sizes similar to those of natural stone. Furthermore, the present invention proposes a method for manufacturing colored glass that can achieve a strong bond between a colorant and a glass material.

As shown in the figure, the glass material 20 used here is made by attaching fine glass powder 22 to a granular glass base material 21 having a particle size distribution within the range of approximately 0.2 to 15 mm via an adhesive 23. A coloring material 25 is attached.

The granular glass substrate 21 is obtained, for example, by crushing transparent plate glass, colored bottle glass, or frit and classifying it into particles having a particle size of about 0.2 to 15 mm. As for the particle size distribution of this granular glass base material 21, as shown in the distribution curve of FIG. 6 or 7, for example, it is best to mix large and small particle sizes in a certain balance in order to obtain a dense glass product with no gaps. It is preferable. Further, the granular glass substrate 21 can be used in an appropriate combination such as transparent or colored (single color, multicolor) or a combination thereof.

The granular glass substrate 21 is made of a suitable adhesive 23, in which one or more of the trade names "Bond", "Hoval", or "Colloidal Silica" are dissolved in water or a solvent. After being immersed and pulled up, or after adding an appropriate amount of adhesive 23 to the granular glass substrate 21 and stirring, a mixture of glassy fine powder 22 and coloring material 25 is quickly added and stirred well to adhere to the outer periphery of the glass granules. be done.

The vitreous fine powder is obtained by crushing transparent plate glass, colored bottle glass, etc. or frit to a size of 0.1 mm or less, and the same material as the base material 21 is preferably used.

The coloring material 25 is made of a known inorganic pigment and metal oxide.

The mixing ratio of the glassy fine powder 22 and the coloring material 25 is determined depending on the degree of fire resistance thereof. Next, examples of mixing ratios and colors are described.

The mixture of the glassy fine powder 22 and the coloring material 25 is applied to the granular glass substrate 21 at a weight ratio of 10 to 10.
0 to 0.3 to 10, preferably 1 to 5.

As shown in FIG. 8, the glass material 20 made of the granular glass substrate 21 to which the mixture of the glassy fine powder 22 and the coloring material 25 is attached is placed in a mold 50 framed in a plate shape. After the glass is introduced into the furnace 51, it is heated at 800 to 1200°C by a known method, and is melt-formed into a plate-shaped glass product. In addition, the reference numeral 52 in the same figure is a stainless steel plate lid used as necessary to provide surface smoothness of the glass product, and the reference numeral 60 is a base material that becomes the base layer of the glass product. Note that FIGS. 9 and 10 are examples of molding without using a base layer.

2 and the coloring material 25 are added and melted. According to this method, a large amount of glassy fine powder 22 and coloring material 25 are applied to the amount of glass substrate 21, resulting in a state in which a colored glass intermediate layer is interposed between the glass substrates, Colored glass with a different and excellent appearance can be obtained.

Furthermore, FIG. 5 relates to a third invention, in which fine glass powder 22 is added to a granular glass substrate 21 so that a transparent glass intermediate layer is interposed in place of the colored glass intermediate layer of the second invention.
A larger amount of vitreous fine powder 22 is applied to the glass material 20 to which a mixture of coloring material 25 and coloring material 25 is attached. Each material and manufacturing method used in the second invention and the third invention are the same as those explained in the first invention, so their explanation will be omitted.

[0025]

As illustrated and explained above, according to the present invention, a coloring material that emits a predetermined color is effectively arranged around a granular glass substrate, and at the same time, this coloring material is further added to a vitreous fine powder. Therefore, when heated to the glass melting temperature, the glassy fine powder melts together with the glass substrate, effectively integrating the coloring material with the molten glass substrate. can. Therefore, the glass products obtained by this manufacturing method were able to obtain a colored glass surface with a deep, solid and luxurious appearance, resembling natural stone such as marble or granite.

Furthermore, according to the present invention, by appropriately interposing a colored glass intermediate layer as in the second invention or a transparent glass intermediate layer as in the third invention, a variety of even more excellent designs can be obtained. You can get that look.
