Hereinafter, a shoe insole according to an embodiment of the present invention will be described in detail with reference to the drawings.
1 is a plan view showing an insole according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. 3 is an enlarged cross-sectional view of a main part of FIG.
As shown in FIG. 1, the shoe insole 1 has an insole body 10 formed in accordance with the shape of the shoe sole, and the insole body 10 includes an insole base sheet material 11 as shown in FIG. It consists of a coating-type finish integrated heat-insulating coating material coating layer 12 laminated on an insole base sheet material 11.

  As shown in FIG. 2, a heat energy reflective coating heat insulating coating material 13 is applied to the surface 11 a of the insole base sheet material 11 of the insole body 1 of the shoe insole 1, and a coating type finish integrated heat insulating coating material coating layer is applied. 12 is integrally formed.

  The manufacture of the shoe insole 1 is performed by applying a thermal energy reflective coating-type heat insulating coating material 13 to the surface 11a of the insole base sheet material 11 of the insole main body 10 by spraying, brush, roller, iron, etc., and then applying the thermal energy reflective coating type. By drying the heat insulating coating material 13 for a predetermined time, the coating-type finishing integrated heat insulating coating material coating layer 12 laminated on the insole base sheet material 11 of the insole body 10 is integrally formed, and the shoe insole 1 is manufactured.

  After drying the heat energy reflective coating heat insulating coating material 13, the surface of the coating type finish integrated heat insulating coating material layer 12 has a water-absorbing ceramic 14 that is lighter than the aluminosilicate soda glass 15, as shown in FIG. 3. A lightweight sodium aluminosilicate glass 15 is collected under the water-absorbing ceramic 14 of the coating-type finish-integrated heat-insulating coating material coating layer 12.

  As the thermal energy reflective coating type heat insulating coating material 13 of the above embodiment, Sista Coat (trade name, manufactured by Nisshin Sangyo Co., Ltd.) is used.

Next, the action of the shoe insole according to the embodiment of the present invention will be described.
First, by putting the insole 1 into the inside of the shoe and laying it on the shoe sole with the application-type finishing integrated heat insulating coating layer 12 of the insole 1 facing upward, , Put on shoes.

  As a result, the hollow bead-structured sodium aluminosilicate glass 15 in the coating-type finish-integrated heat-insulating coating material coating layer 12 efficiently reflects the heat energy (body temperature) emitted from the legs of the human body into the coating film, thereby applying the coating. The thermal energy that escapes to the outside of the coating finish integrated heat insulating coating layer 12 is contained by the sodium aluminosilicate glass 15 to suppress the heat radiation to the outside of the coating finishing integrated heat insulating coating layer 12, Thermal insulation effect is enhanced.

  Further, the water-absorbing ceramic 14 in the coating-type finish-integrated heat-insulating coating material layer 12 absorbs moisture such as sweat that comes out of the human foot, and the aluminosilicate soda glass 15 raises the temperature of the water-absorbing ceramic 14 to absorb water.

  Further, the water-absorbing ceramic 14 in the coating-type finish-integrated heat-insulating coating material layer 12 absorbs and decomposes the odor generated in the shoe to deodorize it, and reduces the odor in the shoe by its deodorizing effect. Can do.

By using a sodium aluminosilicate glass 15 having a hollow bead structure and a particle size of 10 to 50 μm as the thermal energy reflecting ceramic, the aluminosilicate soda glass 15 reflects the thermal energy emitted from the human foot. Since the glass 15 has a hollow bead structure, heat energy for escaping to the outside of the coating-type finishing integrated heat insulating coating layer 12 is contained in the hollow bead portion. The heat dissipation to the outside can be suppressed, and the warming effect in the shoes can be enhanced.
Therefore, the thermal conductivity of the thermal energy reflective coating type heat insulating coating material 13 can be set to a very low value in the range of about 0.03 to 0.05 with respect to the conventional heat insulating material.

  Further, since the heat energy reflecting ceramic is made of the hollow bead-structured sodium aluminosilicate glass 15, the specific gravity is very light as about 0.10 to 0.13, so that the aluminosilicate soda glass 15 is not precipitated. The thermal energy reflective coating type heat insulating coating material 13 can be easily applied, and the thermal energy reflective coating type heat insulating coating material 13 is uniformly spread by spray, brush, roller, iron, etc. It can apply | coat to the surface 11a of the material 11, and can apply | coat uniformly also on an uneven surface especially.

  Further, since the aluminosilicate soda glass 15 is very light and the water-absorbing ceramic 14 is lighter than the aluminosilicate soda glass 15, it is coated on the insole base sheet material 11 of the insole body 1 of the shoe insole 1. By forming the integral heat insulating coating layer 12, as shown in FIG. 3, the lightweight water-absorbing ceramics 14 are gathered on the surface of the coating type finish integral heat insulating coating layer 12 to form a water-absorbing and diverging layer. In addition, since the lightweight sodium aluminosilicate glass 15 is gathered under the water-absorbing ceramic 14 of the coating-type finish-integrated heat-insulating coating material layer 12 to form a waterproof heat energy reflecting layer, The aluminosilicate soda glass 15 protects the entire coating-type finish integrated thermal insulation coating layer 12, and the coating-type finish. Durability of integrated heat insulating coating material coating layer 12 is greatly enhanced.

  Further, since the heat energy reflective coating type heat insulating coating material 13 contains a resin emulsion, the coating type finish integrated heat insulating coating material coating layer 12 is excellent in water resistance and has a thickness of about 0.4 to 0.8 mm. The coating type finish-integrated heat-insulating coating material coating layer 12 does not crack and is excellent in durability.

In this example, as an example of the thermal energy reflective coating type heat insulating coating material 13, aluminosilicate soda glass having a hollow bead structure having a particle size of 10 to 50 μm and a specific gravity of 0.10 to 0.13 ( 14.8 parts by weight of trade name XOL-200), 19.5 parts by weight of titanium dioxide as a pigment, 60.7 parts by weight of a water-soluble acrylic emulsion resin as a resin emulsion, and 2 parts by weight of a dispersant In addition, 0.8 parts by weight of the pressure-sensitive adhesive and 2.2 parts by weight of butyl cellosolve as a solvent are added, and 10 parts by weight of water is added to this and mixed sufficiently with stirring. An energy reflective coating type heat insulating coating material 13 is obtained.
This liquid thermal energy reflective coating type heat insulating coating material 13 has an overall specific gravity of 0.7 to 0.9.
However, the butyl cellsolve as the solvent of the thermal energy reflective coating type heat insulating coating material 13 can be omitted as necessary.

  In addition, when this thermal energy reflective coating type heat insulating coating material 13 is applied to the surface 11a of the insole base sheet material 11 of the insole body 1 of the shoe insole 1, dirt attached to the surface 11a of the insole base sheet material 11 is completely removed. Then, it is necessary to apply the thermal energy reflective coating type heat insulating coating material 13 to the surface 11 a of the insole base sheet material 11.

  A thermal energy reflective coating type heat insulating coating material 13 is applied to the surface 11a of the insole base sheet material 11 of the insole body 1 of the shoe insole 1, and the insole which becomes the thickness of the thermal energy reflective coating type heat insulating coating material 13 in a dry state. By setting the layer thickness t of the coating-type finish-integrated heat-insulating coating material layer 12 laminated on the base sheet material 11 to about 0.8 mm, the thermal conductivity is as low as about 0.03 to 0.05. A heat insulating layer is obtained.

  Further, the heat energy reflective coating heat insulating coating material 13 is water-soluble, and the thermal energy reflective coating heat insulating coating material 13 can be easily applied to the surface 11 a of the insole base sheet material 11 of the insole 1 of the shoe insole 1. Since it can apply | coat, a heat insulation layer can be provided very cheaply compared with the conventional heat insulation coating material.

  In the above embodiment, an acrylic emulsion is used as the resin emulsion of the heat energy reflective coating type heat insulating coating material 13, but a urethane emulsion, an epoxy emulsion, or the like can also be used.

  In addition, the resin emulsion of the heat energy reflective coating type heat insulating coating material 13 is not limited to water solubility, and may be an oily emulsion. In this case, an oily solvent such as thinner or toluene is used.

  Furthermore, in the said Example, although titanium dioxide is used as a pigment of the heat energy reflection type coating-type heat insulation coating material 13, and obtained the outstanding white generation effect etc., it replaces with this and other white pigments Can also be used.

  In addition, what was shown in the said Example is an example of the heat energy reflection type coating-type heat insulation coating material 13, and it implements it variously changing especially about the composition of the material of the heat energy reflection type coating-type heat insulation coating material 13.
