  As shown in FIG. 2, the heat insulating ceramic layer 3 is a layer of heat insulating ceramic paint composed of acrylic silicon resin 4 and ceramic particles 5, and specifically, GAINA (registered trademark) manufactured by Nisshin Sangyo Co., Ltd. It is coated with a coating film thickness of 400 to 600 μm. In addition, it can color in arbitrary colors by adding a pigment to a heat insulation ceramic coating material.

The method of applying the heat insulating ceramic coating to the heat insulating base material 2 is to first clean the surface of the heat insulating base material 2 by removing dirt, rust, mold, etc., and heat insulating materials such as primers, sealers, surfacers, binders, and plastics. A coating base material selected according to the type of the substrate 2 is applied. Next, the heat insulating ceramic coating is applied by brush coating, roller coating, trowel coating, spraying with an air gun or the like, and then naturally dried for about 2 hours in summer and about 4 hours in winter. The heat insulating ceramic paint is applied 0.2 kg / m ² × 2 times for heat insulation and heat insulation, and 0.23 kg / m ² × 2 times for heat insulation, heat insulation and sound insulation.

Further, far infrared rays are emitted from the ceramic grains 5 of the heat insulating ceramic layer 3 to control the heat of the coating film. Thus, the heat insulating material 1 of the present invention exhibits excellent heat insulating properties due to the synergistic effect of the heat insulating action of the heat insulating base material 2 and the heat insulating action of the heat insulating ceramic layer 3.

  Moreover, since the heat insulating material 1 of the present invention reduces the temperature difference between the inside and outside of the room, it prevents the occurrence of condensation and mold. Further, since the multilayer ceramic particles 5 of the heat insulating ceramic layer 3 reflect and absorb sound, there is a sound insulation / soundproof effect. Furthermore, the multilayer ceramic particles 5 of the heat insulating ceramic layer 3 have nonflammability.

  FIG. 3 shows a heat insulating material 1a of the present invention using a magnet sheet 2a as a heat insulating base material.
