Hereinafter, the method for producing the co-operative clay of the present invention will be described in detail as follows.

FIG. 1 is a flow chart for explaining a method for producing coagulated clay according to the present invention. The present invention firstly comprises the steps of (a) preparing a coagulated pearlite structure of perlite The pulverization is carried out in the form of powder having a size of 20 to 200 mu m by using a pulverizer.

The pearlite of the pearlite structure is not toxic to humans and animals, and the pH is neutral, so that it does not harm the skin of young children. In particular, It is covered with small small pores, so that the surface has a relatively large surface area, so that an antimicrobial material of an environmentally friendly material easily penetrates between the pores, thereby improving stability and functionality.

Also, in step (b), 2.5 to 3.0% by weight of polyvinyl acetate, 13.4 to 13.86% by weight of glycerin and 13.46% by weight of glycerin are mixed together with 54 to 58% 0.5 to 0.8% by weight of an inorganic pigment (pigment) having a hue is added to the primary mixer, and at this time, a curing agent composed of borax and an antimicrobial agent of an environmentally friendly material are put into the primary mixer together, The input of the step (b) charged into the car mixer is first mixed at room temperature for 2 to 5 minutes by rotating the mixer at a high speed of 3000 rpm.

The polyvinyl acetate added together with the perlite powder enables the viscosity of the co clay to be maintained constantly while the glycerin softens the coagulant clay, .

In addition, the co-working clay is mixed with inorganic pigments (pigments) made of iron oxide to easily obtain the inorganic pigment and maintain the non-toxicity and stability. In addition, the antibacterial agent of the environment- The function of the hand clay is to protect the skin of young children.

On the other hand, when the amount of the perchloric acid powder injected into the primary mixer is less than 54% by weight, the mixing amount of the polyvinyl acetate to be mixed together is less than 2.5% by weight so that sufficient viscosity of the co clay can not be maintained , And the perlite powders are mixed in an amount of 54 to 58 wt%.

In addition, when glycerin added to the primary mixer is mixed with 13.86 wt% or more, the tactile feel of the coagulant clay increases, but it becomes difficult to maintain a stable viscosity, and the viscosity of the coagulant clay becomes low, It is not possible to maintain the sculpture because it is easily broken when molding the coagulated clay, and when the glycerin is mixed in the content of 13.4% by weight or less, the coagulated clay is not softened and the sensation of touch is deteriorated. The amount of glycerin added is preferably 13.4 to 13.86 wt%.

In addition, by mixing 2.5 wt% of distilled water with respect to the total weight% of the mixture during the primary mixing in the step (c), the mixture can be smoothly mixed in the primary mixer, It is harmless to the human body by distilled water.

Also, the mixture in the primary mixer can be quickly and uniformly mixed by primary mixing the input materials of the step (b) by high-speed rotation at a rotational speed of 3000 rpm for 2 to 5 minutes at room temperature, As the production time of the coagulating clay is shortened, the coagulated clay mixture can be mixed in a uniform state.

Next, in step (d), 25.6 to 28.4% by weight of propylene glycol is added to the interior of the secondary mixer together with the mixture having been subjected to the primary mixing in the step (c), and the mixture is stirred at room temperature for 3 to 8 minutes Followed by secondary mixing at a rotation speed of 1000 rpm.

In step (d), the propylene glycol having the formula C3H8O2 is separately mixed with the primary mixture in step (c) through the secondary mixer, so that the coagulated clay does not easily harden over time, The viscosity of the coagulant clay is maintained for a long time so that the clay material can be used repeatedly for a long time.

Particularly, when 28.4% by weight or more of propylene glycol is mixed with the primary mixture of step (c) through the secondary mixer, the coagulated clay is not easily aggregated, and the primary mixture of step (c) And the propylene glycol is mixed with the propylene glycol in an amount of 25.6% by weight or less, the coagulated clay easily hardens in the air and can not be used repeatedly. The propylene glycol mixed in the secondary mixer together with the primary mixture propylene glycol) of 25.6 to 28.4% by weight.

Further, by sufficiently mixing the primary mixture and the primary mixture in the secondary mixer at a rotational speed of 1000 rpm for 3 to 8 minutes at room temperature with the primary mixture, the coagulant mixture is easily and readily uniform To be mixed with each other.

In the step (e), the second co-operative clay mixture of step (d) is transferred into the aging chamber and dried at room temperature for 24 hours to complete the coagulated clay.

Thus, the coagulated clay that has been dried as described above can be repetitively united and loosened. Since the coagulated clay has the characteristic that after the production of the sculpture, there is no deformation of the shape of the sculpture, will be.
