The present invention relates to a color clay and a method of manufacturing the same, and more particularly, to a natural weapon that is harmless to the human body, has no pastel color and no discoloration, and is used for various purposes such as filling other than working. The present invention relates to a color clay using a pigment and a natural binder, and a method of manufacturing the same.

In general, the working clay is flexible so that it can be easily transformed into a desired shape by hand, which is easy to manufacture a variety of moldings, and when hardened, it is hardened so that the product is maintained for a long time.

These co-working clays initially used high-weight inorganic materials collected from nature, but they are heavy, have low moisture content, and have a short molding time. It has a problem such as losing.

In addition, to reduce the weight of clay, artificially manufactured and used clay using water-soluble natural polymer such as starch or its derivatives, but when dried, the volume of clay is greatly reduced, resulting in cracking of the sculpture and severely cracking or shattering. This is difficult, there is a problem that discoloration during drying, leaving debris in the hands during work.

Moreover, starch clays are much lighter than inorganic clays, but they are still heavy for women and children to use, they are difficult to form due to their deformability, and if they cannot be completed in a short time due to the rapid evaporation of moisture, the clay is easily hardened. There is a problem that it is not easy.

In order to solve the above-mentioned problems, recently, a working clay made of synthetic resin, artificial dye, and the like has been proposed. For example, a predetermined amount of polyvinyl chloride, diethylhexyl butyrate, dibutyl butyrate, calcium carbonate, and polydimethylsiloxane (silicone rubber) is added to a stirrer, followed by mixing and stirring, Proposed and used.

However, in the case of conventional clay, it is possible to maintain proper viscosity at all times even if stored for a long period of time, and workability is excellent. It is easy to handle clays of different colors at the same time because it does not get on the hands of workers, but it is mainly composed of chemicals, so it cannot be seen as a hygienic and environmentally friendly product. Therefore, there are problems that are not suitable for use as children's general learning materials.

In other words, most of the existing working clay is made by stirring with primary color chemical or oxidation pigment and vinyl chloride resin, and endocrine obstruction of children is detected and heavy metal is contained, so it is urgent to regulate the use of clay.

At this time, the natural inorganic pigment is a natural soil or minerals of various colors, such as yellow earth, brown earth, wormwood earth (muzal), purple earth, white earth, black earth, etc., about 200 to 400 mesh (preferably, about 325 mesh) Can be obtained by grinding.

In addition, the natural soil is a raw soil that can be easily collected from the surrounding mountains or fields, and then dried and pulverized and then screened with a particle size of about 1 mm, for example, a general concept such as clay, mud, loess, sandy soil, sandy loam, masato, etc. It is possible to include all soils in the soil and to avoid corrosive organics.

The clay is a fine soil particle having a diameter of about 0.004 mm or less, and when it contains moisture as a particulate aggregate of nature, it shows plasticity, and when it is dried, it shows rigidity. The loess is a deposit composed mainly of particles having a diameter of about 0.002 to 0.005 mm in diameter. It is mainly mixed with sand and clay. It is a honeycomb structure with a wide surface, so it has a large pore like a sponge, so it is weak against moisture and east sea. A large amount of far-infrared rays are stored in the pores, and due to the large number of microorganisms and enzymes, they are known to be very beneficial to humans and animals and plants.

Next, the natural inorganic pigment powder and the natural binder (binder) prepared in step S100, for example, put into a high speed stirrer to perform mixing and stirring (S200). Thereafter, for example, the vacuum produced by cutting the mixture produced in the step S200 to a predetermined size through a vacuum de-airing Pug mill (S300).
