泡性防火延焼塗料が使用されている。2. Description of the Related Art In recent years, various kinds of materials have been used for building materials, but a large amount of plywood and plastic combustible building materials are also used. Moreover,
As buildings are becoming taller at the same time, once a fire occurs, many lives may be lost. For this reason, in order to make buildings incombustible, it is becoming standard to adopt building materials that have been made incombustible for interior parts and the like. However, the coating applied to interior parts and the like has conventionally been a source for generating smoke and harmful gas by immediately burning when exposed to a flame or the like, because the coating film is formed of an organic component. In addition, since halogen-based treatment agents are often used for flame-retardant treatment of plastics, etc., when the coating film burns, the plastic building material that has undergone flame-retardant treatment is directly exposed to flames and spreads fire. Then, a large amount of smoke and toxic gas will be generated. For this reason, in order to prevent the building materials, etc. from being directly exposed to flames, etc., they foam when heated and form a heat insulating layer on the coated surface of the application body, which is a foaming fire spread prevention function that exerts the fire spreading function of the building materials etc. Paint is used.

造法を提案することにある。According to the foamable fire spread coating, when a fire is generated and exposed to a flame or the like, the foaming agent foams to form a heat insulating layer on the coated surface. If the building material is not directly exposed to flames and can be extinguished while the heat insulating layer is being formed, it is possible to prevent the building material from spreading. However, the foamable fire spread coating composition is inferior in heat resistance because it is composed of organic components such as paraform [(HCHO) x ], ammonium dihydrogen phosphate as a foaming agent, urea, and starch. For this reason, it takes a short time until the paint burns and the building materials are directly exposed to flames, and fire spreads to the building materials during evacuation activities and fire extinguishing activities, generating smoke and toxic gas, and evacuation activities and fire fighting activities. May be disturbed. Therefore,
An object of the present invention is to improve the heat resistance of a coating film, and even if the coating film is exposed to a flame or the like due to a fire or the like, it is possible to prevent the spread of the coating body by protecting the coating body from the flame or the like. And to propose a manufacturing method thereof.

製造法でもある。Means for Solving the Problems The inventors of the present invention have conducted extensive studies to achieve the above-mentioned object, and as a result, obtained by blending magnesium carbonate in an inorganic pressure-sensitive adhesive containing water glass as a main component. According to the paint, even if the flammable coating body formed by applying the paint to form a vitreous coating film is exposed to a flame, the coating film of the portion directly exposed to the flame expands to cause the flammable coating body from the flame. They have found that they can protect and prevent fire spread to a flammable coated body, and have reached the present invention. That is, the present invention is a fireproof coating comprising an inorganic compound which forms a glassy heat-resistant coating film on the surface of a coated body, when the coating film is exposed to a flame or the like, a gas is generated and the coating film and the coated body surface are exposed. And a gas-generating inorganic compound such as magnesium carbonate is mixed with the inorganic compound forming the coating film so as to form a void between the coating composition and the coating material. Further, the present invention, in an inorganic pressure-sensitive adhesive mainly composed of water glass, after adding a heat-resistant inorganic compound such as silica and stirring, when exposed to a flame or the like, such as magnesium carbonate which generates a gas. It is also a method for producing a fire-preventive coating characterized by adding a gas-generating inorganic compound and stirring.

塗料は優れた防火性能を奏することができるのである。According to the present invention, when the coating film is exposed to a flame as a high temperature source, a gas is generated due to the thermal decomposition of the gas-generating inorganic compound such as magnesium carbonate contained in the coating film. Then, a void is formed between the coating film and the surface of the coated body. The voids are filled with gas generated by air, a dust-generating inorganic compound, or the like, and serve as a heat insulating layer. Further, since the coating film is a glassy heat-resistant coating film made of an inorganic compound, the coating film does not easily spread by radiant heat from a high heat source such as a flame. For this reason, the flameproof coating composition of the present invention can exhibit excellent fireproof performance as a result of the coating body being protected from the high heat source by the gap as the heat insulating layer formed between the coating film and the surface of the coating body.

ができるのである。When the glass-like coating film containing the gas-generating inorganic compound is formed on the coated surface and exposed to a high temperature source such as a flame, it causes thermal decomposition of the gas-generating inorganic compound. Gas is generated, and a gap is formed between the coating film and the coated surface of the coated body by the gas pressure. Therefore, a heat insulating layer filled with the generated gas, air, or the like is formed in the formed gap. In addition, since the vitreous coating film has heat resistance and is nonflammable, the coating film does not easily melt or burn even when exposed to heat radiation from a high temperature source such as a flame, so that the heat insulating layer is formed. Can be protected for a long time. Therefore, since the coated body is protected by the coating film and the heat insulating layer against radiant heat from a high heat source such as a flame, the spread of the coated body can be prevented.

When the amount of the gas-generating inorganic compound added is less than 3% by weight, the amount of generated gas is small and there is a tendency that sufficient voids cannot be formed between the coating film and the coated surface, while the amount of gas generation exceeding 10% by weight. The effect of adding a water-soluble inorganic compound tends to be saturated. Further, when adding the gas-generating inorganic compound, various inorganic compounds can be added.
