No. 36145). The foam described in this publication is to obtain a foam by stirring and mixing a phosphoric acid such as a metal phosphate and a foaming agent such as a polyvalent metal carbonate and foaming and curing the following. Because of these characteristics, it can be positioned as an unprecedented superior material, for example, it can be applied not only to a fixed material such as a panel but also to an irregular filler for filling an opening. (1) The obtained foam is excellent in nonflammability and fire resistance. (2) In producing a foam, specific gravity control over a wide range can be easily performed. (3) Self-foaming.

きるとしている。[0003] However, the foam of phosphoric acid is fragile because it is a completely inorganic material, and has a drawback that the foam formed by even a small force is destroyed and cannot be restored. Particularly, a large panel having a low specific gravity is produced. In such a case, the surface layer is destroyed only by touching, and the panel strength is too weak to be carried around. As a means for improving the disadvantages of such a phosphoric acid foam, a method has been proposed in which a resin emulsion such as SBR is added into the system (for example, JP-A-6-24869). In this method, the strength of the foam is improved by adding a resin emulsion to such an extent that the excellent nonflammability and heat resistance characteristic of the foam of phosphoric acid are not impaired, and the foam is practically used even in a foam having a high expansion ratio. It is said that it is possible to obtain an excellent material.

However, it is difficult to obtain a foam having flexibility and resilience of plastic foams such as urethane foam and styrene foam.

見を得た。Means for Solving the Problems The present inventors have conducted intensive studies to solve these problems of the conventional phosphoric acid foam, and as a result, unlike the above resin emulsion, when foaming and curing, the polymer was polymerized. Thus, a foam containing a water-insoluble crosslinked polymer of an ethylenically unsaturated monomer formed as described above was obtained. Further, as a result of the study of the present inventors, when this crosslinked polymer is used, when a foam having a high expansion ratio is obtained, a foam having toughness and strength is obtained despite being an organic-inorganic composite. It has been found that the expansion ratio is hard and the brittleness is remarkably improved.

For example, the hardness of the foam is improved by adding the cement (d1). Among the cements (d1), alumina cement is preferable in that it has low reactivity with the phosphoric acids (a) because it has low alkalinity even in cement. The addition of the inorganic fiber (d4) improves the tensile strength and the bending strength of the foam and the shape retention after the organic substances in the foam are temporarily burned. In addition, aluminum hydroxide and calcium carbonate in (d5) improve the fire prevention performance by being added. Others exemplified as (d) can be used mainly as an increasing material for cost reduction. The amount of (d) added is not particularly limited, and is usually 1800 parts by weight or less, preferably 500 parts by weight or less, based on 100 parts by weight of phosphoric acid (a). Organic fibers can be used in place of or in combination with the inorganic fibers (d4). Organic fibers also have the effect of improving the tensile strength and bending strength of the foam. Examples of the organic fiber include vinylon fiber, polyamide fiber, acrylic fiber, polyester fiber, polypropylene fiber, and cellulose fiber. However, the amount of the organic fibers used must be within a range that does not cause any problem in consideration of the required level of the fire protection performance of the foam.

(3) Since it can be produced even under conditions of normal temperature and normal pressure, a special reaction device such as autoclave curing is not required. (4) It can be easily made porous in a mold having a desired shape and can be cured. It is also possible to perform troweling, spraying, and the like on the wall surface to cure the wall. (5) Although the appearance and performance are almost at the same level as existing rigid urethane foam and styrene foam, the fire resistance of the material is equivalent to non-combustible to quasi-incombustible materials which are higher than these existing organic heat insulating materials. It is a material of a high level and can supply materials with high safety in disaster prevention to the market.
