一性のおそれ等があった。The present inventors have been researching compositions with excellent fire-resistant performance, including fire-resistant coating materials with the above-mentioned properties, for quite some time, and have already completed several useful inventions. Most of them have water-soluble alkali metal silicate, its hardening agent, foaming agent, and foaming stabilizer as essential components, and these component systems may be used alone or in addition to silica dust, gypsum, or substances with a high degree of hydration. After blending or adding special fine powder to form a paste, a coating layer is formed by any coating method. On the other hand, the present inventor continued to study the above-mentioned component system without using a self-foaming agent, and also succeeded in inventing some useful compositions. However, even if a strong cured coating layer can be formed with the above-mentioned composition having excellent fire resistance, some problems still remain. [III,
Problems with workability due to the use of water-soluble alkali gold silicates with high alkalinity, problems with weather resistance that make it difficult to use externally, and poor cosmetic properties because the coating layer is quite alkaline. There were problems, such as the problem that the weight of the covering layer becomes considerably large, the problem that the thickness of the covering layer becomes considerably large in the case of a foamed covering layer, and the risk of non-uniformity of foaming due to poor workmanship.
