を有するスレート基板のアルカリにより天然突板が変色
し、アルカリ汚染を生ずるという問題がある。Conventionally, this type of noncombustible decorative board is made by first applying an alkali-resistant sealer such as urethane or acrylic to the slate base material before bonding the natural wood veneer to the slate base material, and then applying a vinyl acetate acrylic or rubber adhesive. The material was coated with an adhesive and bonded under heat. However, since the adhesive in this non-combustible decorative board is a solution type, the adhesive layer is not uniform due to the application method, pinholes (contamination of foreign matter), uneven application, and flow due to heat and pressure. There is a problem in that the natural veneer changes color due to the alkali in it, resulting in alkali contamination.
そこで、このアルカリ汚染を防止するためには接着剤

の目的は、簡単な手段によりアルカリ汚染を確実に防止
てきる不燃化粧板を提供することである。Therefore, in order to prevent this alkali contamination, increase the amount of adhesive applied or the amount of alkali-resistant sealer applied (for example, increase to 8 to 10 y/sha. (approximately 88 to 110 da/g)). There are several methods: using a weakly alkaline base material, and using a veneer that is more alkaline resistant, but all of them have their drawbacks. Therefore, an object of the present invention is to provide a noncombustible decorative board that can reliably prevent alkali contamination by simple means.

により突板４のアルカリによる変色汚染を防止できる。That is, this noncombustible decorative board is made by coating an alkaline noncombustible base material 1 such as slate, calcium silicate, or pulp cement with an alkali-resistant sealer 2 such as urethane resin or acrylic resin (step A), and then applying the coating to a predetermined temperature (80°C to 200°C). ℃) (Step B) and then apply a layer of vinyl resin, polyolefin resin, or other material containing the same type and components as Sealer 2 with a layer thickness of 30μ or more (optimally 50μ) to sealer 2. The alkaline hot-melt adhesive sheet 3 and the natural wood veneer 4 are stacked and hot-press-molded (step C). Furthermore, a base paint is applied to the surface of the veneer 4 (Step D), this is sanded (Step E), and a top coat is applied (Step F).
The surface resin layer 5 is formed by drying (step G). This layer 5 is made of aminoalkyd resin, urethane resin, acrylic resin, polyester resin, or the like. This non-combustible decorative board has the upper and lower surfaces of the hot melt adhesive sheet 3 at a heating temperature (
Since the adhesive layer melts and flows at a temperature of 80° C. to 2,000° C. and does not melt in the intermediate portion, a constant layer thickness can be obtained from the intermediate portion, and this adhesive layer can prevent discoloration and contamination of the veneer 4 due to alkali.

施例である。That is, in the first embodiment, this noncombustible decorative board is made by pasting the hot melt adhesive sheet 3' larger than the size of the base material 1, and then pasting it on the side surface of the base material through the protruding portion 3''a. The other aspects are the same as the first embodiment.As described above, the noncombustible decorative board of the present invention is made of a noncombustible base material, an alkali-resistant sealer layer, and a veneer. In this product, an alkali-resistant hot-melt adhesive sheet is interposed between the sealer layer and the veneer, and the upper and lower surfaces of this sealer are used to melt and bond, making it possible to reliably prevent contamination of the veneer by alkali on the base material with a simple method. The following is an example.

Thereafter, urethane resin paint was applied from the surface at a rate of 3 y/shaku2 (approximately 33 y/d) and dried. This noncombustible decorative board did not discolor due to alkali contamination of natural veneer.
