【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention and is a schematic view of a state in which an artificial snow image is formed. The one shown in FIG. 2 shows a state before being shaped as an artificial snow image, and is a state of only a frame to be transported for exhibition. In this example, a hollow snowman-shaped object 1 is formed by a heat insulating material such as styrofoam, and the object 1 is placed on an exhibition stand 6 having a refrigerator 5. A copper cooling pipe 4 extending from the refrigerator 5 is spirally wound around the surface of the shaped article 1 and piped, and the cooling pipe 4 is supported and fixed by a tape or band such as an aluminum material. In the cooling pipe 4, a refrigerant 4A such as CFC cooled below freezing point supplied from a refrigerator 5 in the display stand 6 driven by a power source in the venue is circulated. The molded article 1 and the display stand 6 containing the refrigerator 5 may be integrally fixed to each other, or the display stand 5 containing the refrigerator 5 and the lower end of the spiral cooling pipe 4 may be formed. May be connected by a detachable connector so that the modeled article 1 having a cooling pipe spirally piped on the surface thereof can be transported separately from the display table 6. The artificial snow image is displayed by laminating the hydrophilic material 3 in the form of a slurry made of a mixture of a super absorbent resin acrylic polymer and water on the surface of the modeled object 1 thus formed by troweling or spraying. Complete things. At this time, the spiral cooling pipe 4 acts as a stopper so that the slurry-like hydrophilic material 3 laminated on the surface of the molded article 1 does not slip off. As shown in FIG. 7 by enlarging the portion A of FIG. 1, the superabsorbent resin acrylic is formed on the surface of the molded article 1 on which the spiral cooling pipe 4 in which the sub-freezing refrigerant 4A circulates is laid. A hydrophilic material 3 in the form of a slurry, in which a system polymer 3A and water 3B are mixed at a weight ratio of 1:70 to 80, is laminated by trowel coating or spraying.

The super-absorbent resin acrylic polymer 3A used in the present invention was developed separately by the applicant of the present invention. As shown in FIG. , Which is basically granular and consists of a cross-linked acrylic acid salt-based polymer having a diameter of 0.02 to 0.5 mm when not absorbing water. As described above, the particles do not stick to each other and form an ice block, and the particles are independent of each other in a granular form. Therefore, the refrigerant 4A in the cooling pipe 4 causes the hydrophilic polymer 3 in the hydrophilic material 3 to be the acrylic polymer. When the granules of 3A are cooled, the frost pillars 3C grow from the superabsorbent polymer acrylic polymer 3A containing a sufficient amount of water, and the frost pillars 3C show a characteristic like snow crystals. is there. Due to the growth of the frost column 3C, the water content in the highly water-absorbent resin acrylic polymer 3A is reduced, but when the frost column 3C slightly melts due to the intermittent operation of the refrigerator 5, this melt-out again occurs. The absorbed water will be absorbed, which will also form frost columns 3 C, and this will be repeated thereafter. FIG. 3 shows an example in which a spiral pipe groove 1A for connecting the cooling pipe 4 is engraved on the surface of a hollow snowman shaped object 1 formed of a heat insulating material such as styrofoam. It is a thing. In this case, since the cooling pipe 4 is reliably piped in the molded article 1 and at the same time the cooling pipe 4 is partially embedded, hydrophilicity in the form of slurry that is laminated to form artificial snow is obtained. It is economical because the formation layer of the material 3 can be thin.

FIG. 4 shows a second embodiment of the present invention. In this example, a hollow snowman shaped article 2 is formed of a material having good heat conductivity such as Al or Fe, and the shaped article 2 is formed. The refrigerator 5 is placed on the display stand 6 that is housed inside. A copper cooling pipe 4 extending from the refrigerator 5 is spirally wound around the inner surface of the shaped article 2 and piped, and the cooling pipe 4 is supported and fixed by a tape or band of aluminum material or the like. Preferably, the inner surface of the shaped article 1 is provided with a spiral recess for the cooling pipe 4, that is, a rib 2A when viewed from the outside, and the rib 2A is similar to the rib of the third embodiment described later. The slurry-like hydrophilic material 3 laminated on the surface of the molded article 1 acts as a stopper so as not to slip off. In the cooling pipe 4, a refrigerant 4A such as CFC cooled below freezing point supplied from a refrigerator 5 in the display stand 6 driven by a power source in the venue is circulated. Similar to the first embodiment, the molded article 1 and the display stand 6 having the refrigerator 5 may be integrally fixed to each other, or the display stand 5 having the refrigerator 5 built therein. The spiral cooling pipe 4 and the lower end of the spiral cooling pipe 4 are connected by a detachable connector so that the shaped object 1 having the cooling pipe spirally piped on the surface thereof can be separately carried with respect to the display table 6. Good. The artificial snow image is displayed by laminating the hydrophilic material 3 in the form of a slurry made of a mixture of a super absorbent resin acrylic polymer and water on the surface of the modeled object 1 thus formed by troweling or spraying. Since the process for completing the object and the subsequent formation of the artificial snow layer is the same as in the first embodiment, the description thereof will be omitted.

FIG. 5 shows a third embodiment of the present invention. In this embodiment, a hollow snowman shaped article 2 is formed of a material having good heat conductivity such as Al or Fe, and the shaped article 2 is As clearly understood from FIG. 6, a spiral or ring-shaped rib 2A similar to the rib in the second embodiment is provided on the surface so as to project outward. The model 2 thus formed is placed on the display stand 6. At the exhibition site, dry ice or a cryogen 7 is put into the inside of the model 2 through the opening of the head of the model 2, and the opening of the head is closed and sealed. The molded article 2 and the display stand 6 may be integrally fixed to each other, or, similarly to the above-mentioned two examples, the molded article 2 may be detachable so that the molded article 2 can be separately carried with respect to the display stand 6. May be. The display stand 6 may be made of a heat insulating material to block heat from the floor of the display space. On the surface of the shaped article 2 shaped in this way, a hydrophilic material 3 in the form of a slurry made of a mixture of a highly water-absorbent resin acrylic polymer and water is ironed or sprayed as in the above-mentioned embodiment. Stacked to complete the artificial snow statue exhibit. Similar to the rib 2A of the second embodiment, the rib 2A acts as a stopper so that the slurry-like hydrophilic material 3 laminated on the surface of the molded article 2 does not slip off. The subsequent process of forming a layer of artificial snow is the same as in the above two examples, and will be omitted. It should be noted that in this example, the hydrophilic material 3 is not cooled by a refrigerator as in the above two examples, but even if it is cooled by dry ice or a freezing agent, the artificial snow image can be used for almost one day. The shape was maintained for about 8 hours, which was equivalent to the exhibition time, and there was no problem.

In the above-described embodiment, the shape of the molded article 1 or 2, the piping shape of the cooling pipe 4, the rib shape, the laminated shape of the hydrophilic material, the related configuration of the molded article and the cooling pipe, and Needless to say, the materials and the like that make up these can be variously modified within the scope of the present invention. In addition, if the artificial snow image according to the present invention is enormous and is to be a permanent facility, it is possible to effectively use the refrigeration cycle by using excess heat such as waste heat of liquefied natural gas (LNG). it can.
