Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a watercolor enamel composition, more specifically, a watercolor enamel composition that can be used as a regular watercolor enamel composition to draw watercolor paintings, and
The present invention relates to a watercolor enamel composition that foams and increases in volume when heated to 1000°C and exhibits a pottery-like appearance (hereinafter referred to as "fired").

Pigments that can be used in the present invention include organic pigments that can be commonly used in watercolor paint compositions such as Hansa Yellow, Cyanine Blue, Virician, Carmine, and Orange; Any pyrotechnic pigment that can be used in watercolor enamel compositions, such as iron NL, can be used, but when firing, it is necessary to use a heat-resistant Nozomi pigment.

In addition to pigments, clay, kaolin, bentonite, calcium carbonate, etc. can be used as a coloring agent, but if firing, it is necessary to use a heat-resistant material.

Examples of water-soluble polymers that can be used in the present invention include natural polymers such as gum arabic and dextrin, cellulose derivatives such as carboxymethyl cellulose and hydroxyethyl cellulose, and synthetic resins such as polyvinyl alcohol and water-soluble acrylic acid resin. However, any water-soluble polymer that can normally be used in watercolor enogu compositions can be used, but in the case of firing, it is desirable to use a polymer with a low ash content after combustion, such as hydroxypropyl cellulose, hydroxyethyl cellulose, etc. It is desirable to use it.

The clay that can be used in the present invention has a composition of 1 jii ratio (%

4→1 Those commercially available under the names of motilialite, agerite, globalite, solite, gallite, nitride or rocklite can be used.

Other humectants include glycerin, ethylene glycol,
Additives that can be used in regular watercolor enogu compositions can be used depending on the purpose, such as preservatives, dispersants, activators to improve the fluidity of enogu, and fusing aids when baking is desired. .

To make one watercolor enogu composition using the ingredients of the first generation, in 100 parts by weight of the composition (hereinafter, the overlapping parts are simply referred to as parts),
6 to 70 parts of pigment, preferably 10 to 80 parts, 1 to 80 parts of water-soluble polymer, preferably 5 to 20 parts, 10 to 65 parts of clay, preferably 20 to 60 parts, 16 to 50 parts of water, preferably 20 parts.
~86 parts are used, as well as 20 parts or less of a humectant, and an extender pigment of 5 parts.
Preferably, 0 parts or less are used. If the amount of pigment exceeds 70 parts, the degree of coloring will be too high, and if it is 10 parts or less, the degree of coloring will be too low. Also, the addition of extender pigments has the effect of making the enamel composition more spreadable and matte. If the amount of the water-soluble polymer exceeds 80 parts, viscosity holes will form and it will be difficult to draw, and gas will be generated during firing, causing large cracks, and if it is less than 6 parts, it will not adhere to the mountain surface. If the viscosity exceeds 66 parts, the color development will be poor, and if the viscosity is less than 1 part, no curing will occur by baking. If you do not use a wetting agent and use it as a regular watercolor enogu composition, enogu will not absorb water easily and will dry too quickly, making it difficult to draw and will easily cause cracks on the screen. The occurrence is large and cracks are likely to occur.

Water may be added by adjusting the viscosity F depending on the purpose.

To prepare the Enogu composition from these ingredients, add 60% water.
While heating to ~80°C and stirring, a water-soluble polymer is added and completely dissolved to obtain a color vehicle. At this time, additives such as wetting agents, preservatives, dispersants, and surfactants are also mixed, dissolved, or fractionated at the same time. Next, pigments, extender pigments, and clay are added and thoroughly blended using a roll mill, three-roll mill, or other means.

Next, examples will be shown to further clarify the invention.

To this color vehicle, 80.0 parts of agerite (clay, produced in America), 12.0 parts of cobalt blue, and 16.0 parts of bentonite were added and thoroughly kneaded using an 8-roll mill to form a blue watercolor enogu composition. I got it. This composition spreads better than normal watercolor paints and can be built up, and is used to draw on unglazed tiles at 800℃*1b after drying.
T? When it was fired in between, only the drawn area foamed and a three-dimensional blue screen was obtained.

This composition showed the same enamel state as Meishi@l, and after being drawn and dried on unglazed pottery, a good yellow three-dimensional screen was obtained by firing at 900° C. for 1 hour.
