Abstract

PROBLEM TO BE SOLVED: To obtain an inorganic cured product excellent in high strength and incombustibility by mixing a cellulosic thickener and zirconium ammonium carbonate into a cement composition. SOLUTION: In producing an inorganic cured product by subjecting a cement composition comprising cement, silica and reinforcing fiber to extrusion molding, a cellulosic thickener and zirconium ammonium carbonate are mixed into the cement composition. The cellulosic thickener in an amount of 1-2 pts.wt. and zirconium ammonium carbonate in an amount of 0.02-0.2 pts.wt. based on 100 pts.wt. cement are preferably used. Well-known cement such as portland cement, blast furnace cement or alumina cement can be used as the cement. Fine powder silica having >=4,000cm<2> /g specific surface area is preferably used. Pulp fiber or organic synthetic fiber can be used as the reinforcing fiber. The cellulosic thickener includes e.g. methyl cellulose or hydroxyethyl cellulose.

きなかった。However, when an inorganic cured material is formed by using an organic fiber as a reinforcing fiber or using a cellulosic thickener as described above, the amount of an organic substance which is easily combustible becomes large. As a result, there is a problem that the nonflammability of the inorganic cured product is reduced, and generally, the use of a cellulose-based thickener increases the cost of the inorganic cured product. Therefore, it is desirable to reduce the amount of the cellulosic thickener used, but this prevents the problem that the cement composition is clogged at the time of molding or the inorganic hardened material is cut and the strength is reduced. I couldn't.

Furthermore, the non-combustibility of the inorganic cured products obtained in Examples 1 to 3 and Comparative Examples 1 to 3 was evaluated. This incombustibility was tested in accordance with the base material test method of the flame retardancy test of JIS A 1321, and evaluated at the rising temperature of each inorganic cured product.

た。As can be seen from Table 1, the inorganic cured product of Comparative Example 1 has high flexural strength due to the large amount of the thickener used.
Thickeners were very flammable and therefore very nonflammable. On the other hand, in the inorganic cured products of Examples 1 to 3, the amount of the thickener was reduced and ammonium zirconium carbonate was used instead. The performance was greatly improved. In the inorganic cured product of Comparative Example 2, the amount of the thickener used was reduced, so that the nonflammability was improved as compared with Comparative Example 1, but the moldability was reduced. Since the amount of the reinforcing fibers used in the body was reduced, the incombustibility was improved as compared with Comparative Example 1, but the bending strength was reduced.
