Abstract

PURPOSE:To produce a rigid marble-like decorative plate having good color tones and luster inexpensively by filling a soln. for forming marble patterns contg. a synthetic resin soln. in the recess enclosed with the projecting edge part formed on the periphery of a transparent glass plate and baking and fixing the same. CONSTITUTION:A transparent glass plate 1 which is formed of a projecting part 1a on the circumference and is formed with a recess 1b on the inner side is molded. On the other hand, White pigments and pigments of the other colors are incompletely mixed in a resin soln. such as an epoxy resin soln., polyester resin soln., acrylic resin soln. or PVC resin soln. to prepare a soln. for forming marble patterns. Said soln. 2 is filled in the above-mentioned recess 1b and the glass plate is put horizontally in a kiln and is baked for about 1hr at about 50 deg.C. The soln. 2 is thus baked and fixed thoroughly in the recess 1b of the plate 1 and the decorative plate having the marble patterns visible therethrough from the opposite side of the plate 1 is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing an astronomical stone-like decorative board using a transparent glass plate and a synthetic resin solution.

Conventionally, a piece of paper with a marble pattern drawn on it is sandwiched between a transparent glass plate and a glass plate, and the peripheral edges of both glass plates are glued together with the paper piece interposed** to create an I-Test board. A method for producing an astronomical decorative board in which a marble pattern can be seen through the surface is known.

However, since the astronomical stone-like decorative boards made by this conventional method are made of glass plates and paper pieces, they are weak in strength and easily break when subjected to even the slightest impact. Although it took a lot of effort to draw, it was significantly inferior to natural marble in terms of color tone and luster, giving it a very cheap impression.

In view of these conventional deficiencies, the present invention provides a method for manufacturing an extremely beautiful and inexpensive astronomical stone-like decorative board that is easy to manufacture, robust, and has a color tone and luster similar to astronomical marble. The purpose is to provide.

That is, the structural feature of the present invention is that pigments of white and other colors are incompletely added to a synthetic resin solution in a recessed part surrounded by the ridge of a transparent glass plate having a ridge around the periphery. This is a method for producing a marble-like decorative plate, in which a mixed marble pattern forming liquid is filled, and then the marble pattern forming liquid is baked and fixed onto the glass plate.

Hereinafter, specific embodiments of the present invention will be described based on the drawings.

First, a transparent rectangular glass plate (1) having a protruding edge (1a) formed around it and a recessed part (1b) formed inside it is molded.

On the other hand, white pigments and pigments of other colors are incompletely mixed in a synthetic resin solution such as an epoxy resin solution, a polyester and fat solution, an acrylic resin solution, or a polyvinyl chloride resin. 2) Manufacture. in this case,
Incomplete mixing means that when adding a pigment to a synthetic resin solution, normally the pigment is stirred until it is completely mixed with the synthetic resin solution, but in this case, the mixing is stopped when the pigment is mixed completely. be. As a result, the marble pattern forming liquid (2) is completed! It will have an appearance similar to natural marble pattern.

After completing the preparation of the transparent glass plate (1) and the marble pattern forming liquid (2) as described above, next the glass plate (1) is prepared.
) is filled with the marble pattern forming liquid (2). Then, the glass plate (1) is placed horizontally in a baking oven and baked at a temperature of 50° C. for about 1 hour. This results in
The marble pattern forming liquid (2) is completely baked and fixed in the concave portion (1b) of the glass plate (1), and a decorative plate (3) whose marble pattern can be seen through from the opposite side of the glass plate (1) is completed. It is something to do.

Since this invention is a method for manufacturing a marble-like decorative plate constructed as described above, it is easy to manufacture, and the marble pattern-forming liquid is fixed on one side of the glass plate, making it extremely durable. Therefore, there is little possibility of damage even if it receives a slight impact. In addition, the marble pattern forming liquid has a natural milky white color obtained by incompletely mixing white and other color pigments with a synthetic resin solution, so the completed decorative board (3) is made of polished natural marble. It has a beautiful appearance and feel with the same color tone and luster as that of the original, and has an extremely high decorative effect.
