。However, when using a construction base material whose substrate is a combustible wood board as a fireproof structural material, the coating layer on the surface of the base material is thickened to reduce the thickness of mortar applied at the construction site. The overall thickness of the fire-retardant material on the outside of the wood board can be increased by either reducing the thickness of the fire-retardant material on the outside of the wood board, or conversely by reducing the coating layer on the substrate surface of the base material and increasing the thickness of mortar applied at the site. In the former case, the building material itself becomes heavy and has poor workability; in the latter case, multiple coats are required, making work and efficiency essential. In order to solve this problem, inorganic boards have been used as the substrate for the base material, but after wall construction, the non-AA board opening
Charcoal caused by carbon dioxide gas in the air! Due to the 2R heat action, it contracts over a long period of time, creating gaps at the joints of the inorganic lightning plates, which causes cracks in the surface of the topcoat material such as mortar applied on the base material along the joints, and the coating material flaking.

の層間の接着力を向上させる。The above-mentioned waterproof layer not only has a waterproof effect, but also flattens the surface of the hydraulic inorganic board, and if the hydraulic inorganic board has a porous surface, it flattens the voids in the recesses of the surface when applying the mixture. (air pockets) and prevent air bubbles from forming at the interface between the hydraulic inorganic plate and the mixture layer. The hydraulic property also increases the adhesion area between the structural plate and the mixture layer. Furthermore, by selecting synthetic resin 1-rubber latex, bituminous material, etc. as MFJJ for the waterproof layer and the mixture layer, the adhesion between the layers is improved by the intermolecular attraction of these materials.

塗材との接着力をも向上させる。Synthetic resin, rubber latex, bituminous substances, etc. in the mixture improve the mixing and adhesion between the main component and the aggregate, and also improve the waterproofness of the mixture layer after curing and the adhesion with the coating material applied on it. It also improves strength.
発明の効果 本発明の効果は下記の通りである。Effect of the invention The effects of the present invention are as follows.
１、下地材における水硬性無機質板と、下地材上に塗布
されるモルタルなどの上塗り塗材とは、防水層と混合物
層とを介して完全に密着される。1. The hydraulic inorganic board of the base material and the top coat material such as mortar applied on the base material are completely adhered to each other via the waterproof layer and the mixture layer.
２、基板として水硬性態ａ質板を使用するため、防火構
造材として使用でき、混合物層及びその上に塗布される
モルタルなどの塗材層を薄くでき、施工性が向上する。2. Since a hydraulic A-grade board is used as the substrate, it can be used as a fireproof structural material, and the mixture layer and coating layer such as mortar applied thereon can be made thinner, improving workability.
３、水硬性無機質板が予め炭酸化処理されているので、
施工後の炭酸化が殆ど生じることがなく、下地材の収縮
による上塗りの割れ、剥落が完全に防止できる。3. Since the hydraulic inorganic board has been carbonated in advance,
There is almost no carbonation after construction, and cracking and peeling of the topcoat due to shrinkage of the base material can be completely prevented.
４、割れ、２す落の防止により、雨水の浸透などによる
建築物の下地構造の腐食が防止できる。4. By preventing cracks and drops, corrosion of the building's base structure due to rainwater penetration can be prevented.
５、混合物層の炭酸ｆヒ処理が行なわれなくても、防水
層を形成することにより、混合物層の収縮による割れが
緩衝され、上塗りに対する影響が緩和される。5. Even if the mixture layer is not subjected to carbonation treatment, by forming a waterproof layer, cracks caused by shrinkage of the mixture layer are buffered and the influence on the top coating is alleviated.
６、混合物層の材料を予め炭酸化処理することにより、
上塗り層の割れが、さらに少なくなる。6. By pre-carbonating the material of the mixture layer,
Cracks in the top coat layer are further reduced.
