た。As is well known, inorganic decorative laminates such as asbestos slate decorative laminates, calcium silicate decorative laminates, and pulp cement decorative laminates generally have poor impact resistance. When used as a building material, some kind of reinforcement is required, but it is generally not easy to reinforce such inorganic decorative boards by laminating FRP, and even if they are lined with FRP, the parts will quickly deteriorate. There were problems such as peeling, and therefore reinforcement in this field was generally done by laminating reinforcing plates such as plywood, steel plates, aluminum plates, etc. with adhesive to form a composite plate. .

From a cost perspective, it is difficult to say that it is advantageous because it requires complicated complex processes and expensive reinforcing plates, and it also has problems such as being difficult to transport and handle because the thickness and weight increase significantly. had.

The purpose is to provide a useful FRP-free inorganic decorative board that can be mass-produced with ease.

以下、図面を参照しながら本考案を詳細に説明する。Hereinafter, the present invention will be described in detail with reference to the drawings.

脂にて予めプライマー処理することが望普れる。The resin decorative layer 2 on the upper surface of the base material 1 can be formed, for example, by placing a resin-impregnated decorative paper cloth on the substrate 1 and bonding it under heat by a force N or a thin resin decorative board (thickness 0.4 to 1.5 mm). The former method is more advantageous in terms of manufacturing method, especially when using the inorganic substrate 1 of the official seal. When thermocompression-bonding the resin decorative layer 2 thereon, it is desirable to prime the surface of the substrate 1 with a resin having high affinity in advance in order to increase the adhesion strength between the resin decorative layer 2 and the inorganic substrate 1. It will be done.

止する役目を果すのである。That is, when forming the above-mentioned resin decorative layer 2, if a highly shrinkable material such as melamine resin-impregnated decorative paper cloth is used, the inorganic substrate 1 will warp due to its shrinkage, but this resin layer 3 The shrinkage force of the resin decorative layer 2 is alleviated or offset by the force, thereby serving to prevent the inorganic substrate 10 from warping.

従って、このような樹脂層３形成の為の部材としては、
樹脂化粧層２に用いる樹脂含浸化粧紙布と同様の樹脂を
ほぼ同量含浸させた紙布類が好適に使用される。Therefore, as a member for forming such a resin layer 3,
Paper cloth impregnated with approximately the same amount of the same resin as the resin-impregnated decorative paper cloth used for the resin decorative layer 2 is preferably used.
