DESCRIPTION OF THE PREFERRED EMBODIMENTS The metal plate used in the present invention is 3 ×
Large-sized ones such as six-foot, four-by-eight-foot are preferable, and stainless steel, copper, aluminum, titanium, plated steel sheets, clad steel sheets, PVC steel sheets, galvalume steel sheets, and the like can be used, and galvalume steel sheets are more preferable. The galvalume steel sheet is a hot-dip aluminum / zinc alloy-plated steel sheet, and is optimal because it has both the corrosion resistance, heat resistance and heat reflection properties of aluminum and the sacrificial corrosion protection of zinc. A galvalume steel plate having a thickness of 0.35 to 1.6 mm is used.

The non-combustible heat insulating material to be adhered to the back surface of the metal plate has a water pressure resistance of 600 kgf / cm ² or more and a bulk specific gravity of 0.
The main material is ^{3 to} 0.5 g / cm3, ceramic hollow particles with a melting point of 1500 ° C. or higher, and phenolic resin is used as a binder, heat-molded into a plate shape, and certified as a noncombustible material by the Ministry of Construction. Is, for example, a resol type phenol resin, methylene chloride as a foaming agent, a water pressure resistance of 700 kgf / cm ² , a bulk density of 0.3 to 0.5 g / cm.

It is a heat insulating material that has been cured and cured at 5 ° C. for 70 minutes and has been approved as a non-combustible material by the Ministry of Construction.

[0012] The non-combustible heat insulating panel is very lightweight, and is attached to the skeleton using a nail or a wood screw when the skeleton is a wooden base.
Self-drilling screw, small screw, hook bolt,
Use a channel bolt or the like. In some cases, they are bonded by an adhesive or the like.

[0013] Waterproof coating materials of the synthetic resin emulsion used in the present invention, which are certified as nonflammable, include acrylic resin emulsions, polyurethane resin emulsions, acetic acid resin emulsions, vinyl chloride resin emulsions, and the like. Examples include vinylidene chloride resin emulsions, styrene / butadiene resin emulsions, epoxy resin emulsions, and copolymers of acrylic acid esters, styrene, ethylene, vinyl esters, vinyl acetate, synthetic rubber, and the like.

For example, copolymers of these include acrylic / vinyl acetate copolymers, vinylidene chloride / butyl acrylate copolymers, ethylene / vinyl acetate copolymers and the like. The amount of the coating film waterproofing material composed of a synthetic resin emulsion is in the range of 5 to 15% by weight in terms of resin solid content. If it is less than 5% by weight, the physical properties of the waterproof coating material do not increase,
If the content is 15% by weight or more, the stability of the waterproof coating material is reduced, and the film does not meet the criteria for the non-combustible coating waterproof material equivalent to the base material.

In order to improve the properties of a non-combustible decorative waterproof coating material to which a waterproof coating material of a synthetic resin emulsion, which has been certified as non-combustible, is added as necessary, various surfactants and emulsions are used as dispersants. Emulsifier, foaming inhibitor, thickener, anti-sagging agent, anti-settling agent, anti-freezing agent for stabilizing emulsion, plasticizer giving flexibility for the purpose of improving performance, preventing deterioration by heat and light You may add a stabilizer, a fungicide for preventing the generation of mold, a composition having a flame-retardant and non-flammable effect, and the like.

The ceramic fine hollow particles used in the present invention have a particularly high compressive strength as compared with conventional fine hollow foams, and are resistant to high stress and shear force generated in the process of producing a non-combustible decorative waterproof coating material. It can withstand.
Furthermore, even if the fine hollow body is applied to a panel or the like with a spray or a roller, the fine hollow body is not destroyed at all.

The compressive strength of the ceramic fine hollow particles or fine hollow foam is synonymous with the water pressure resistance. The compressive strength is measured by pressing the fine hollow foam in water and applying a pressure applied to the water to the fine hollow foam. The pressure transmitted to the foam and broken by the fine hollow foam is defined as the compressive strength.

A non-combustible cosmetic waterproof coating material capable of exhibiting excellent performance must have a sufficient stirring and kneading process, and is particularly important for a uniform product and good quality non-combustible cosmetic waterproof coating material. When the composition is sufficiently stirred and kneaded as in the present invention, the stress and shear force applied to the ceramic fine hollow particles are about 400 kgf / cm ² .
None of the conventional fine hollow foams could withstand such high pressure, and none of them could be used as such non-combustible makeup waterproof coating materials to obtain sufficient performance. That is, most of them are destroyed.

When ceramic fine hollow particles are used in a non-combustible decorative waterproof coating material, an important factor is a reflectance to light. The reflectance of the fine hollow foam is generally 20% or less depending on the particle size, and the reflectance when half of the mixed and stirred fine hollow foam is broken is reduced to about 5 to 10%. An excellent decorative effect can only be obtained if a completely fine hollow foam which is not destroyed is used.
The ceramic fine hollow particles used in the present invention have significantly higher compressive strength than conventional fine hollow foams such as shirasu balloons, glass balloons, silica balloons, fly ash balloons, etc. Are 100% perfectly spherical.
Compressive strength of conventional fine hollow foam is 80-300kgf
/ Cm ² .

The melting point of the fine hollow ceramic particles used in the present invention is 1500 ° C. or higher. Naturally, the fine ceramic hollow particles are caused by their material, but generally, the higher the melting point, the higher the compressive strength. Compressive strength 600k
If gf / cm ² or more, the melting point becomes 1500 ° C. or more.

As described above, the ceramic fine hollow particles used in the present invention are composed of 50-60% of silica and 40% of alumina.
A ceramic composition comprising -45% and 1.5-2.5% is formed by foaming. Its physical properties include a compressive strength of 700 kgf / cm ² , a melting point of 1600 ° C., a bulk specific gravity of 0.3 to 0.5 g / cm ³ , and a thermal conductivity of 0.1 (kca).

Of the range of 5 to 75 μm, 75 to
The particle size is adjusted to 150 μm and coarseness of 150 to 350 μm by mixing 20 parts by weight of fine, 20 parts by weight of medium and 30 parts by weight of coarse. The bulk specific gravity is heavy for fine particles and light for rough ones. For this reason, the range of the bulk specific gravity is 0.3 to
0.5 g / cm ³ , but the particle size adjusted is 0.3 g / cm ^3.
It is around 6 g / cm ³ .

The color of the crushed ceramic waste particles differs depending on the original ceramic product, and a unique texture can be obtained by blending them in various ways. For example, it is possible to express a completely new tile-like pattern, which has not existed conventionally, by adding an appropriate amount of white mesh particles of sanitary ware waste particles to coarse and fine ground particles of brick waste particles.

Examples of the pigment used in the present invention include titanium oxide, zinc white, zinc sulfate, lead white, antimony oxide,
Carbon black, graphite, zinc yellow, zinc yellow, loess, shenar, Mars Yellow, Strontium Yellow,
