Various methods have been proposed for obtaining a foamed hardened material, but all of them involve foaming hydraulic cement slurry using the foaming pressure of gas generated when a urethane prepolymer reacts with water. However, in this method, since the specific gravity of hydraulic cement is high, in order to obtain a large expansion ratio, it was necessary to increase the amount of urethane prepolymer added. Furthermore, if the proportion of the urethane prepolymer, which is an organic substance, increases, the combustibility characteristics of the finally obtained foam cured product will be significantly reduced, and the hardness and nonflammability of the inorganic material will disappear.

On the other hand, the process is carried out by mixing a separately prepared foam liquid, and then in the second step, a urethane polymer having excellent flexibility and adhesiveness is blended into the foam-containing slurry.

る。More specifically, the present invention uses a mixture of gypsum and basic blast furnace slag in the first invention, Portland cement in the second invention, and hemihydrate gypsum in the third invention as inorganic hydraulic cement or hydraulic gypsum. , a foam liquid created by a foam generator is mixed with hydraulic cement slurry or hydraulic gypsum slurry to which additives such as thickeners and pigments have been added, and a urethane prepolymer is added to this foam-containing slurry. Utilizing the hydraulic properties of the urethane prepolymer, it hardens rapidly, allowing any processing such as molding or cutting to be carried out immediately after, significantly increasing the molding time of conventional foams that only use hydraulic cement. This is a shortened version.

させることによって達成せしめることができる。After adding pigments and kneading with water to form a slurry, a bubble solution is added and mixed to form a foam-containing slurry, and then a urethane prepolymer, which is a reaction product of polyokene alkylene polyol ether and polyisocyanate, is added. This can be achieved by curing.
本発明の第１発明でいう石膏とは、２水石膏。The gypsum referred to in the first aspect of the present invention is dihydrate gypsum.

である。Either gypsum hemihydrate or gypsum anhydrite may be used, and by-product gypsum such as phosphogypsum may also be used as long as it is stable and normally used industrially. The reason why gypsum hemihydrate is used in the third invention is that gypsum that is normally hydraulic refers to gypsum hemihydrate.

This slurry is transferred by a pump with good wear resistance such as a gear pump or a Moino bomb, and is then combined with the foamed liquid at a stage before being transferred to a mixing transfer device such as a static mixer. This bubble liquid can be produced by simply mixing compressed air and an aqueous solution such as a bubble stabilizer so that they are dispersed in a closed container.If this container is filled with spheres or net-like bodies, bubbles will not be produced at the outlet of the container. can do.

うのが能率的であると考えられる。The foam-containing slurry produced by the above steps needs to be rapidly cured in order to continuously produce the hydraulic foam as defined in the present invention and to increase production efficiency. For this reason, in the present invention, when a urethane prepolymer is added to the foam-containing slurry and mixed with stirring, the foam-containing slurry is rapidly hardened and highly efficient productivity can be obtained. Therefore,
It is believed that it is efficient to add the urethane prepolymer at the face of the molding process.

、水硬セメントの特性が発現せずに硬度等が低くなる。The urethane prepolymer may be added to the foam-containing slurry by quantitative mixing using a static mixer, stirring mixer, or the like. The amount of urethane prepolymer to be added at this time is 1 to 3 % based on the total dry weight of hydraulic powder such as gypsum and blast furnace slag used in the present invention.
Must be in the range 0% by weight. If the amount is less than 1% by weight, the flexibility of the cured foamed product will be poor and cracks will occur when external force is applied. Moreover, if it exceeds 30% by weight, not only the nonflammability referred to in the present invention cannot be obtained, but also the properties of hydraulic cement will not be exhibited and the hardness etc. will be low.
