につき詳細説明する。What is commonly used as a binder for inorganic fibers is
The organic binder is starch paste, phenolic resin, etc., and the inorganic binder is cement, water glass, etc. However, when the former is used, it is flammable and smoke or harmful gas is generated. When using, the non-combustibility is obtained, but the adhesive strength between the cement and the surface of the fiber is weak, so high strength is not obtained, and the specific gravity becomes large because the cement fills the voids between the fibers. , Processability, and workability deteriorate. The present invention is. In order to solve the above-mentioned problems, rock wool, on the surface of artificial mineral fibers such as slazwool, it was made as a result of various studies on inorganic binders that react with the fiber components and obtain a strong binding force. It has succeeded in obtaining a completely new building material that has never been obtained. That is, on the surface of artificial mineral fibers such as rock wool and slag wool, an inorganic binder containing a hydroxide of an alkali metal or an alkaline earth metal such as calcium sulfate and calcium hydroxide chemically reacts in the presence of water. As a result of various researches, it was found that strong bonding force can be obtained at the crossing points of the fibers. The artificial mineral fiber molding according to the present invention has a three-dimensional three-dimensional structure that is firmly bonded by the binder at the intersections of the fibers, and has a hollow gap inside, so that it is used as a building material. It has excellent performance such as heat insulation, heat retention, sound insulation, and sound absorption, and has good habitability. Furthermore, because of its light weight and high strength, it is easy to handle and work, and it is also suitable for cutting, nailing, and hanging. It is as easy as wood and has very good workability. That is, it is lightweight and has high strength, heat insulation and sound insulation and sound absorption, which has never been obtained before.
The present invention succeeds in obtaining an ideal building material which has fireproof property, good workability and workability, and which can be said to be an incombustible artificial wood which satisfies all the above conditions. The present invention will be described in detail below.

32H 2 O and monosulfate type C 3 A · CaSO 4
There is 12H 2 O, the former is also called ettringite, which is a needle crystal, and the latter is a hexagonal plate crystal, which rapidly crystallizes on the surface of the artificial mineral fiber by the hydration reaction. This reaction is the first step of the formation reaction of ettringite C 3 A + 3 (CaSO 4 .2H 2 O) + 26H 2 O → C 3 A ・ 3CaSO 4・ 32H 2 O Change to sulphate 2C 3 A + C 3 A ・ 3CaSO 4・ 32H 2 O + 4H 2
O → 3 (3C 3 A · CaSO 4 · 12H 2 O) occurs, and as the third step, the following solid solution formation reaction is performed between the hydroxylate double salt produced in the same manner as above. The solid solution formation reaction of (4) is considered to be most influential in the above reaction system. In these reaction systems, if the amount of calcium sulfate is too large, the reaction in the first step is prolonged, the amount of ettringite is too large, and the strength development as a binder is weak. On the other hand, if the amount of calcium sulfate is not too large, the reaction in the first step will be completed promptly, the monosulfate formation of ettringite in the second step will proceed rapidly, and part of it will change to the solid solution in the third step. To develop a strong binding force. In this solid solution formation reaction, the strongest bending strength is obtained when the ratio of alkali metal hydroxide or alkaline earth metal hydroxide such as calcium dihydrate sulfate: calcium hydroxide is in the range of 1: 1 to 2.5: 1. It also has freeze-thaw resistance of 3

につき述べる。The amount of the artificial mineral fiber used in the artificial mineral fiber molded body of the present invention is usually 5 to 80% by weight in all the composition components.
Further, the type and amount of the inorganic binder containing a hydroxide of an alkali metal or an alkaline earth metal such as calcium dihydrate sulfate and calcium hydroxide are determined by the type and component of the artificial mineral fiber used and the molding thereof. The amount used depends on the performance required for the body and the use, but the amount used is 6 to 50% by weight of calcium dihydrogenate in the total solid composition, and the hydroxide of an alkali metal or alkaline earth metal such as calcium hydroxide is used. In the range of 6 to 20% by weight. In the molded product according to the present invention, its bulk specific gravity can be adjusted by changing the amount of water to be mixed. That is, when the molded body is dried, the water contained therein evaporates and scatters to become porous, so that if the amount of water to be mixed is large, the bulk specific gravity is small, and if the amount of water is small, the bulk specific gravity is large. . The relationship between the amount of water to be mixed and the bulk specific gravity differs depending on the type and amount of the inorganic binder, the inorganic filler, etc. in the components, but generally the bulk specific gravity of the molded product is 0.4 to 1.2. In order to achieve the
