Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention is directed to a ceramic or glass-made ceramic or glass-made product which has a surface similar to that of copperware by coating the surface of the ceramic or glass with a colored pigment. Concerning methods of coloring utensils.

(Prior Art) Traditionally, pottery or porcelain is a vessel made of clay or stone powder made into a predetermined shape and coated with glaze to give it a glossy appearance, and is used for vases, incense burners, and ornaments. The application of this glaze prevents water from leaking from the utensils, makes them unbreakable and durable, and gives them a smooth appearance.

On the other hand, copperware is a vessel made of copper (mainly brass and bronze), and is also often used for vases, incense burners, and ornaments. This generally gives the impression that it is a more luxurious item than ceramics.

(Problem to be solved by the invention) By the way, attempts have been made to use ceramics that can be produced at a relatively low cost to give the surface of the ceramics an appearance unique to copperware. Because the surface was smooth, it was not possible to closely apply the coloring that gave the appearance of copperware to the surface.

Therefore, this invention was made based on the above-mentioned circumstances, and provides a method for coloring ceramics or glassware, in which the smooth outer surface of the ceramics is closely coated with the unique hue of copperware, which gives an image of luxury goods. The purpose is to provide.

[Structure of the invention]

(Means for Solving the Problems) The method for coloring ceramics or glass vessels according to the present invention is a method for coloring ceramics or glass vessels made of glazed and fired ceramics or glass. After applying the mold epoxy resin paint, the patterned surface was painted with paint, and the patterned surface was sprayed with metal powder dispersed in an organic solvent, and the surface to which the metal powder was attached was colored by dispersion treatment. After that, the metal powder was fixed and the painted surface was polished.

(Example) Examples of the present invention will be specifically described below.

The vessel used in this example is a bottle-shaped ceramic vase, and the surface of the vase is made smooth by glaze. The surface of this vase is colored through the following steps.

(1) Pre-treatment process - First, wipe the surface of the vase with thinner or triclean to remove dust and dirt adhering to the surface. This is to improve the adhesion of the undercoat film in the next treatment.

■Next, add 10% to 2% xylene to the main component of the epoxy resin.
A base resin containing 0% and 5% to 10% of methyl isobutyl ketone and a curing agent containing 50% to 60% of xylene mixed with polyamide amine were used for 100c6 of the main resin and 2% of the curing agent.
Mix at a ratio of 0 core to 30 core and stir thoroughly for 20 minutes or more.
After aging for 30 minutes, add 110 to 120 g of thinner.
This is applied to the surface of the treated vase by spraying it using an air sprayer. Thereafter, this is left to dry in a natural state (20° C.) for approximately 8 hours to form a first undercoat film on the surface of the vase. This first undercoat adheres strongly to the surface of the vase and has a rough coating surface, with a film thickness of approximately 15 to 25 microns.

In this case, for the main agent and curing agent, Primer White for undercoat, which is commercially available from Dainippon Toyo Co., Ltd. under the trade name Ebonics #3100, was used. In addition, as the drying means, a drying oven (] (110°C
When forced drying using ~120℃, 15 minutes ~
It is possible to sufficiently dry it in 20 minutes.

(2) Next, a paint having almost the same composition as the above-mentioned main agent and curing agent is air sprayed onto the entire surface of the first undercoat film to form a second undercoat film. The main agent and curing agent used here are those commercially available from Dai 11 Honto Toyo Co., Ltd. under the trade name Ebonix #10.
The difference from the paint used when forming the first undercoat film is that the amount of xylene mixed into the main component of the epoxy resin is 20%.
The only difference is that it is larger by ~30%, and other components such as the main agent and curing agent, the mixing ratio, etc. are all the same. However, regarding drying after spraying the second base coat,
Natural drying takes 8 hours or more, and forced drying using a drying oven takes 20 to 25 minutes.

In this way, a second undercoat film having a thickness of 15 μm to 25 μm is formed, and the rough surface of the first undercoat film is made into a moderately smooth surface.

(2) Coloring process - Paint lacquer enamel containing black pigment by air spraying on the upper surface of the laminated first and second undercoat films.

■After this base coat black lacquer dries, lacquer enamel paint containing red or blue pigment is further sprayed using an air sprayer through so-called ferrules with a large number of holes punched in various pattern shapes to create patterns.

■Next, gold powder (or silver powder) is dispersed in a solvent containing approximately equal amounts of oil-based varnish and gum turpentine oil, and this is sprayed thinly and evenly over the entire outside of the patterned vase.

■Next, before the solvent dries, use a soft cloth impregnated with gum turpentine oil to lightly tap the surface on which the gold powder is attached and sprinkle it around the area so as to make the gold powder flicker. Appropriately disperse gold powder on the base pattern surface.

3) Post-treatment process Finally, a transparent clear lacquer (modified acrylic lacquer) was sprayed on the colored surface to fix a rich gold powder, and the colored surface was polished.

The coloring applied to the surface of the vase through the production process becomes a luxurious line-colored pattern, giving it a profound and deep appearance unique to copperware.

The coloring process described in the above examples was applied to ceramic lead vessels (
In the example, the specific process over time is for a vase (vase), but it is also possible to color a similar pattern on glass vessels through the same coloring process.

〔Effect of the invention〕

As explained above, according to the coloring method of the present invention, even ceramic lead and glass vessels with smooth surfaces can be colored in a line pattern. It is possible to create a product that gives an image of luxury, as if it were made of copperware.

Claims (1)
