[Specific explanation of the device]

 Hereinafter, a heat insulating decorative panel according to an embodiment of the present invention will be specifically described with reference to the drawings.

As shown in FIG. 1, the heat insulating decorative panel according to the present embodiment is formed of a base material 2 made of a material having a specific quasi non-combustibility or higher and a ceramic layer 1 as a skin layer. Become.

Ceramic Layer The ceramic layer 1 constituting the skin layer of the heat-insulating decorative panel according to this embodiment is formed by pressing ceramic particles.

In the present specification, the “ceramic particles” are preferably crushed particles which are crushed ceramics, and are not intended to be crushed, and include particles that have been formed into particles from the beginning. is there.

Ceramics have 20 or more kinds of colors, and various combinations of colors, sizes, shapes, etc. of ceramic particles can give a variety of designs or makeups to the panel surface.

As the above-mentioned ceramics, specifically, old ceramics and new ceramics can be used, but preferably old ceramics are used. The ceramic colored with a pigment or the like may be crushed.

The shape of the ceramic particles forming the ceramic layer 1 used in this example is preferably crushed, and thus may be various shapes. For example, as shown in FIG. As shown, there are various shapes such as a short rod shape, a petal shape, an acute angle shape, an obtuse angle shape, and an arc shape. The size of the ceramic particles is 0.1 mm to 15 mm, preferably 1 mm to 10 mm, and more preferably 2 mm to 7 mm.

The ceramics layer 1 used in this embodiment is obtained by pressing ceramics particles with an organic adhesive made of epoxy resin, phenolic resin, urethane resin, rubber resin, vinyl acetate resin or the like. .. As a result, the ceramic particles are not closely adhered to each other, but a gap is left between the particles to allow air to pass therethrough. As described above, since the ceramics layer 1 has air permeability, it is possible to exhibit sound absorption.

However, it can be formed by bonding using an inorganic adhesive such as so-called water glass. In this case, the resulting ceramic layer 1 tends to have poor air permeability, and is not so good in sound absorption as compared with the ceramic layer 1 obtained by using the organic adhesive as described above. Therefore, water glass can be used for applications where sound absorption is not so required.

The amount of the adhesive used varies depending on the kind of the adhesive, but in the case of the organic adhesive, it is used in an amount of 10% by weight or less, preferably 5% by weight or less with respect to 100% by weight of the ceramic particles. .. This is because when the amount of the organic adhesive used exceeds 10% by weight, the obtained decorative panel may deteriorate in performance as a quasi-incombustible material.

In this embodiment, the ceramic layer 1 formed by using the adhesive has a small amount of the adhesive, and therefore has good air permeability and excellent sound absorption, and has a fire resistance performance of quasi non-combustibility or higher. Have.

Further, the ceramic layer 1 used in this example can also be formed by heating and fusing ceramic particles at a high temperature, usually at a temperature of 1,500 to 2,000 ° C. By controlling the fusing temperature at this time, the degree of adhesion of the ceramic particles can be arbitrarily changed, so that the sound absorption characteristics of the ceramic layer 1 can be controlled.

The ceramic layer 1 formed by heating and fusing ceramic particles has good air permeability and excellent sound absorption, and also has a fire resistance performance of quasi non-combustibility or higher. Further, the thickness of the ceramic layer 1 is 0.5 mm or more, preferably 1.0 mm or more, and more preferably 2 mm or more. The size of the ceramic layer 1 is preferably a square tile or larger, and the size can be obtained depending on the application, but is, for example, a panel of about 3 × 6 or a panel of 6 × 6.

In the present embodiment, the surface of the ceramic layer 1 may be coated with a transparent resin paint. Substrate used in the substrate according to the second embodiment is constituted by a semi-incombustible or more materials, shall be the main component vinyl chloride resin or a chlorinated vinyl chloride resin containing an inorganic filler foams Consists of.

Here, the term “quasi non-combustible or higher” means quasi non-combustible or non-combustible, and is defined by Ministry of Construction Notification No. 1372 of 1984 and Ministry of Construction Notification No. 1828 of 1972, respectively. ..

Specific examples of the vinyl chloride resin include a vinyl chloride homopolymer or a vinyl chloride copolymer having a vinyl chloride polymer content of 50% by weight or more, and further, these vinyl chloride resins. Resins that are compatible with the polymer and vinyl chloride (co) polymer, such as vinyl chloride-vinyl acetate copolymer, thermoplastic polyurethane resin, acrylonitonyl-butadiene copolymer, chlorinated vinyl chloride resin, chlorine A mixture of at least one resin selected from the group consisting of modified polyethylene, methacrylic acid ester-acrylic acid ester copolymer, ethylene-vinyl acetate copolymer, vinyl chloride-vinylidene chloride copolymer, A mixture having a vinyl chloride polymer content of 50% by weight or more is included.

The chlorinated vinyl chloride resin is not only a resin obtained by chlorinating the above vinyl chloride resin, but also a blend having compatibility with a chlorinated vinyl chloride resin and a chlorinated vinyl chloride polymer. Resins such as vinyl chloride resin, vinyl chloride-vinyl acetate copolymer, thermoplastic polyurethane resin, acrylonitonyl-butadiene copolymer, chlorinated polyethylene, methacrylic acid ester-acrylic acid ester copolymer, ethylene-vinyl acetate copolymer A mixture comprising at least one resin such as a polymer and a vinyl chloride-vinylidene chloride copolymer, in which the blending resin content is 50% by weight or less is also used. As the vinyl chloride resin to be chlorinated, a copolymer having a vinyl chloride polymer content of 50% by weight or more can also be used.

Examples of the inorganic filler mixed in the vinyl chloride resin and the chlorinated vinyl chloride resin as described above include inorganic fibrous substances and inorganic granular substances. In particular, the inorganic fibrous material is preferable because it has a good volume retention effect when exposed to a high temperature.

Specific examples of the inorganic fibrous material include glass fibers having an average fiber length of 1 μm or more, preferably about 10 μm to 50 mm, asbestos, rock wool, ceramic fibers, alumina fibers, carbon fibers, and quartz fibers. , Boron fibers, various metal fibers, various whiskers, and the like. These fibers may be used alone or in combination of two or more. Of these, rock wool is most preferred because of its ease of foam molding, various properties of the resulting foam, and cost.

Specific examples of the inorganic particles include talc, calcium carbonate, aluminum hydroxide, magnesium hydroxide, and zinc oxide having an average particle diameter of 0.01 to 300 μm, preferably 0.01 to 100 μm. , Mica, bentonite, clay, silica and the like are preferably used.

The compounding amount of the above-mentioned inorganic filler is determined in consideration of the amount to be contained in the foam, the expansion ratio of the foam and the cost. In this embodiment, the inorganic fibrous substance is usually 2 parts by weight or more, preferably 5 parts by weight or more, and more preferably 1 part by weight with respect to 100 parts by weight of the vinyl chloride resin and / or the chlorinated vinyl chloride resin. It is used in a proportion of 0 parts by weight or more. The inorganic particles are usually used in a proportion of 198 parts by weight or more, preferably 300 parts by weight or more, based on 100 parts by weight of the vinyl chloride resin and / or chlorinated vinyl chloride resin.

As described above, the base material 2 used in the present embodiment is made of a foam containing a vinyl chloride resin containing an inorganic filler or a chlorinated vinyl chloride resin as a main component. The body is an application of the same applicant, which uses a specific solvent and contains a large amount of rock wool and the like, which is not particularly hygienic, and enables high foaming, for example, International Application PCT / JP89 / 00362. It can be produced by the method disclosed in the specification or JP-A-63-264645.

The expansion ratio of these foams containing an inorganic filler is preferably 50 times or more, and when the calorific value at the time of combustion, the amount of smoke generation and the economical efficiency are taken into consideration, the foaming ratio is further increased. It is desirable to foam, and it is preferably 60 times or more, more preferably 80 times or more. However, if the expansion ratio exceeds 200 times, it will be difficult to produce a normal foam, and even if a good foam is obtained, the physical properties such as strength will be insufficient, so 200 times The following is preferable.

The base material 2 used in this example is lightweight, has excellent heat insulating properties, and has a quasi-noncombustible or higher fire resistance. The thickness of the base material 2 is about 5 to 15 mm when the heat insulating property is not provided, and is about 15 to 50 mm when the heat insulating property is provided.
