材の温度上昇を押さえ燃えにくくする。(Operation) When a slurry obtained by adding water to a mixed powder of magnesium oxide and ammonium phosphate is applied to the first layer of the heat insulating material, the slurry impregnates the heat insulating material and hardens. Therefore, there is no need for a bonding step of bonding a molded and reaction-cured material such as a flexible board. The slurry is obtained by adding water to a mixed powder of magnesium oxide and ammonium phosphate. The present inventors have cited a reaction cured product of aluminum phosphate and magnesium oxide as a prior application. (Patent Application No. 3979 of 1988)
Here, these reaction hardened products are hardened by an exothermic reaction, so the reaction rapidly progressed from the beginning and it was necessary to adjust the pot life.Therefore, a method of forming a powder layer in advance and spraying it with water to react was used. Avoided life issues. Usually, even when an aqueous solution of ammonium phosphate is added to the powder of magnesium oxide, the reaction becomes an exothermic reaction from the beginning and proceeds rapidly and hardens, so there is no room for ironing or the like. On the other hand, when the ammonium phosphate powder is used, when the ammonium phosphate powder is dissolved in water as shown in FIG. 7, an endothermic reaction occurs and the temperature of the solution decreases, and the reaction between ammonium phosphate and magnesium oxide is temporarily suppressed. Therefore, pot life (pot life) can be secured. For this reason, it became possible to perform a series of operations of applying the slurry on the surface of the first layer of the foamed heat insulating material and curing the slurry by reaction. Next, since the reaction-hardened product of the slurry contains water of crystallization, it has fire resistance, and when applied to the surface of the first layer of heat insulating material and cured by reaction, not only improves the fire resistance, but also improves the internal resistance. It suppresses the temperature rise of the heat insulating material and makes it difficult to burn.

にも使用できる。Next, when a silicone resin coating composition using a polymer or oligomer having a molecular weight of 10,000 or less consisting of an alkoxy-substituted organosilane as a third layer is applied and impregnated, the acidic layer in the reaction-cured product of magnesium oxide and ammonium phosphate is applied to the third layer. The curing of the silicone resin is accelerated to form a strong coating film. Moreover, since the resin has a low surface energy, it has excellent water repellency, excellent stain resistance and greatly improved weather resistance. It can be used for ceilings as well as floors.
