の使用に際しては材料の取扱いが面倒であった。The present inventors have been researching compositions with excellent fireproof performance, including fireproof coating materials with the above-mentioned properties, for quite some time, and have already completed several useful inventions. One of them is a specific range of formulations of compositions containing as active ingredients hydraulic cement, lightweight aggregate and highly hydrated substances, which are used especially for architectural fireproof coating applications. It was found that it exhibits extremely excellent fire resistance performance when exposed to heat. However, when such a composition is actually applied as a fireproof coating material, the following problems still occur. That is, (1) when applying a subsequent decorative finish, for example, if paint is used as a decorative finishing material, it will last for a relatively short period of time, but over a long period of time it will cause discoloration, peeling, etc. (2) The aggregate used may scatter and peel during spraying, (3) Comparison It is easy to peel off from the base at low temperatures, for example, about 100°C. In order to solve these problems, in the field of concrete and mortar, it has been suggested that water-soluble cellulose admixtures and water-dispersed synthetic resin emulsions be used in cement. It is rarely used in cases such as the present invention, where it is necessary to mix a fairly large amount of lightweight aggregate or highly hydrated material, and the above (1) can be expected to be quite promising, and in fact, good improvements have been made. However, the above-mentioned problems (2) and (3) are still not solved, and in addition, they need to be formulated as an aqueous solution or dispersion, so the packaging form of the fireproof coating composition is The material is separated and difficult to handle in actual use.

役立つのである。The present invention aims to solve the above problems,
By blending a considerable amount of a material with a high degree of hydration into hydraulic cement, it exhibits considerable fire resistance, and by further blending a specific amount of lightweight aggregate, -M fire resistance is improved, and it is also lightweight. Furthermore, by blending a specific amount of re-emulsifiable synthetic resin emulsion powder, it prevents the lightweight aggregate used from scattering, and prevents the fire-resistant coating layer from peeling off when heated at relatively low temperatures, making it a decorative finishing material. It has become possible to almost satisfy all of the above requirements required for fireproof coating materials, such as maintaining finish stability for a long period of time, and furthermore, these formulations can be used as a mixed powder in just one form. Since it can be put into practical use by packaging (simply mixing water at the work site), it is also very useful in actual work.

That is, when using a water-soluble alkali metal silicate as a binder, it has been used in an amount of about 20%, and when using a hydraulic cement as a binder, it has been used in an amount of about 30%). One of the major features of the present invention is that it is used together with lightweight aggregate as a component. Therefore, the degree of hydration refers to the degree to which an object heated and stabilized at 100°C releases a larger amount of water when heated to a higher temperature, and the degree of hydration in the present invention is A substance with a large value is defined as 100 parts by weight at a constant temperature of 100°C,
