Description
More particularly, the present invention relates to a method of manufacturing a cloisonna metal decorative plate, and more particularly to a method of manufacturing a cloisonna metal decorative plate by silver plating on a metal plate except for gold or silver, The present invention relates to a method for manufacturing a cloisonné metal decorative plate having a low manufacturing cost as well as an excellent merchantability and a cloisonné metallic decorative plate by the method.
It is a technique to apply glass glaze to the base metal and to fix it to the base metal by high temperature heat treatment at 700 ~ 820 ℃. The cloisonne ornament using this technique is a metal oxide (gold-red color , Silver oxide-opaque yellow color system, copper oxide green color system, etc.) are colored in various colors through heat treatment, and they are used as various crafts and household goods or their ornaments by coloring with beautiful colors in addition to the color of base metal.
The glassy glaze (hereinafter referred to as "clay glaze") used in these clay crafts is well adhered to any metal, and its thermal expansion coefficient and cooling shrinkage are similar to those of metal, Since it does not corrode well and has no affinity with water, it has excellent cold resistance and fire resistance, and its life span is semi-permanent within the range of not being damaged by external force.
It is common to use red copper as the base metal of the above-mentioned Cloisonne craft, but it also uses gold, silver, and tombac (alloy of copper and zinc).
When gold or silver is used as the base metal, the color of the metal is bright and it is not oxidized through the small phase, so that the color appearance of the cloisonne glaze is excellent, but the price is high. In addition, gold or silver is difficult to design through corrosion or electrification, so that there is a limit to expression of various patterns.
When copper or copper alloy is used as the base metal, the manufacturing cost can be lowered, and various designs can be achieved through methods such as electric pole and corrosion. However, the color of the base metal is red, There were disadvantages. In other words, in order to decorate the base metal with cloisonne, the cloisonne glaze must be placed on the base metal and heated to a high temperature to be melted on the base metal. When the cloisonne glaze is heated to a high temperature, the base metal is inevitably heated, The surface of the metal is oxidized and becomes dark. Therefore, when the copper or copper alloy is heated, the red copper is oxidized and changed into a dark color oxidizing copper (CuO), so that the bottom part of the cloisonne glaze, which has almost transparent color, becomes black, There was a problem.
In order to overcome this disadvantage, copper or copper alloy is used as the base metal, first treated with white glaze, then fired, and then treated with cloisonne glaze. However, this method has disadvantages in that the copper wire is treated with a metallic wire by engraving the pattern on a copper plate and then the metallic wire is not expressed well when the white glaze is treated. In addition, after the white glaze treatment, the metal wire is again bonded to the white glaze, and then the cloisonne glaze is treated. However, the manufacturing process is troublesome and the metal wire is bonded to the white glaze. there was.
For this purpose, Korean Patent No. 10-1418169 discloses a method of forming a metal plate by stamping a silver thin film on a protruding portion of a pressing mold when engraving a pattern on a metal plate, heating the metal plate with a high temperature, A silver thin film was formed on the pattern forming part. In this method, the intrinsic hue of the cloisonne glaze was well represented due to the silver thin film. However, there is a limitation in the method of forming the pattern, the silver foil film can not be laminated on the formed metal wire, or the appearance is not clean even when laminated, there was.
Accordingly, an object of the present invention is to solve the problems of the above-mentioned conventional cloisonne board, wherein silver plating is applied to a metal plate except for gold or silver, and then the cloisonne glaze is treated, Which is excellent in merchantability and low in manufacturing cost.
In addition, it is possible to design a variety of patterns such as corrosion and electric pole, but it is also possible to process a lacquer glaze directly on a metal plate, so that it is possible to express various patterns with precision.
In addition, the manufacturing process is simple, and the cloisonne glaze is not easily peeled off, thereby providing a durable cloisonn metal plate.
According to another aspect of the present invention, there is provided a method of manufacturing a cloisonna metal decorative plate, comprising the steps of: selecting a metal plate; forming a pattern on the selected metal plate; nickel plating the metal plate with the pattern; Silver plating the plated metal sheet, and treating the silver plated metal plate with a cloisonnal glaze.
The step of nickel plating the patterned metal plate may include degreasing the patterned metal plate, treating the degreased metal plate with a weak acid, and subjecting the slightly acid treated metal plate to a plating solution containing nickel chloride and hydrochloric acid Nickel plating; and nickel plating the nickel plated metal plate with a plating solution containing sulfuric acid (sulfuric acid) nickel, nickel chloride, boric acid and a brightener.
The step of silver plating the nickel-plated metal sheet comprises the steps of: silver-plating the nickel-plated metal sheet with a plating solution containing silver cyanide and potassium cyanide; and coating the silver-plated metal plate with silver cyanide, Potassium, and a brightener; and a step of honing the surface of the final silver-plated metal sheet with sodium bicarbonate, and drying the honed metal plate.
The step of treating the silver plated metal plate with the cloisonne glaze includes the steps of: first treating the cloisonne glaze according to the pattern of the silver plated metal plate; A first sintering step for 3 minutes; a second step of treating the first sintered metal plate with a quill glaze; and a second step of sintering the second quill glaze treated metal plate in an electric furnace at 700 to 820 DEG C for 2 to 3 minutes Treating the second sintered metal plate with a transparent glaze; and finally sintering the metal plate treated with the transparent glaze at 700 to 820 ° C for 2 to 3 minutes in an electric furnace.
The cloisonne metal decorative panel according to the present invention is advantageous in that it has excellent color development, excellent appearance, high durability, high commercial value, and low manufacturing cost and high added value.
