本発明は、極めて高強度の石膏製品を与える無機質繊維
強化石膏組成物に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to mineral fiber reinforced gypsum compositions that provide extremely high strength gypsum products.
近年建築技術の発展は著しく、建造物の高層化及び大型

た一方においては、火災の発生及びその延焼防止等の観
点から、不燃性の建築資材が要求されている。In recent years, construction technology has made remarkable progress, and as buildings become taller and larger, building materials need to be made with higher strength. construction materials are in demand.
この様な事情から、種々の無機質建材が検討されており

る事が期待できないという問題点を有する。Under these circumstances, various inorganic building materials are being considered, and recently the effective use of surplus gypsum discharged from flue gas desulfurization equipment in the chemical industry has attracted attention, and various companies are conducting various research, especially on gypsum products. Research is being actively conducted to increase the strength of steel. A known method for obtaining high-strength gypsum products is to reinforce gypsum with various fiber materials, but it is difficult to expect a significant improvement in strength due to the poor adhesion between the gypsum and fiber materials. There are problems.

従来には得られなかつた極めて高強度の無機質繊維強化
石膏製品が得られる事を発見し、本発明に至つた。Another method is to mix various polymers with plaster,
Methods of reinforcing fibers using various fiber materials are known, but they have the problem that materials and costs are high due to the use of expensive polymers. In order to solve these problems, the present inventors conducted intensive studies and found that a gypsum composition containing gypsum and at least one type of silicate other than water glass and sodium silicate is a material that contains inorganic fibers. By reinforcing the composition with inorganic fibers, especially glass fibers,
It was discovered that an inorganic fiber-reinforced gypsum product with extremely high strength, which could not be obtained in the past, could be obtained, leading to the present invention.
本発明に用いられる石膏としては、α型半水石膏、β型
半水石膏等がある。Examples of the gypsum used in the present invention include α-type hemihydrate gypsum and β-type hemihydrate gypsum.

高強度の無機質繊維強化石膏製品を与える働きを有する
。These plasters can be used alone or in combination. Silicates other than water glass and sodium silicate, which are the constituent components of the present invention, improve the adhesion between the gypsum composition and inorganic fibers by blending these two components into gypsum, resulting in extremely high strength inorganic fiber reinforcement. It has the function of giving plaster products.
本発明の構成成分である水ガラスの配合量を、石膏１０
０重量部に対し、１５．０重量部より多くすると瞬結性
となり、作業性に問題があると同時に石膏組成物の強度
が低下する傾向にある。The amount of water glass, which is a component of the present invention, is 10% of gypsum.
When the amount exceeds 15.0 parts by weight compared to 0 parts by weight, instant setting occurs, which causes problems in workability and tends to reduce the strength of the gypsum composition.
又、０．５重量部より少なくすると無機質繊維との接着

グネシウム、珪酸アルミニウム等がある。Furthermore, if the amount is less than 0.5 parts by weight, the adhesion with inorganic fibers will deteriorate and it will not be possible to obtain an extremely high-strength inorganic fiber reinforced gypsum product, so a range of 0.5 to 15.0 parts by weight is desirable. . Silicates other than sodium silicate, which are constituent components of the present invention, include calcium silicate, magnesium silicate, aluminum silicate, and the like.
これら珪酸塩は、単独又は混合して配合する事がてきる

クスファイバー等がある。These silicates can be used alone or in combination. If the blending amount of these silicates is at least 0.5 parts by weight or more than 15.0 parts by weight per 1 (4) parts by weight of plaster, the adhesion to inorganic fibers decreases and becomes extremely high. Since it is difficult to expect to obtain a strong inorganic fiber reinforced gypsum product, the amount of silicates other than sodium silicate is preferably in the range of 0.5 to 15.0 parts by weight per 10 parts of gypsum. Inorganic fibers used in the present invention include:
There are asbestos fibers, rock wool, glass fibers, ceramic fibers, etc.

なくすると、石膏組成物の流動性が低下し、成形作業性
が悪くなる。Among these inorganic fibers, glass fiber is particularly desirable because it has good dispersibility in the gypsum composition and has a high reinforcing effect. If the blending amount of these inorganic fibers is less than 0.1 part by weight per 10 parts of gypsum, it will not be possible to obtain an extremely high-strength inorganic fiber-reinforced gypsum product.
(a) If the amount exceeds 1 part by weight, the fluidity of the gypsum composition will decrease, which will not only worsen the molding workability, but also the dispersion state of the inorganic fibers will deteriorate and the strength will tend to decrease. The amount is 0.1 to 10 parts of plaster.
A range of 3 salivary parts is desirable. If the amount of water used in the present invention is less than 100 parts by weight per 100 parts by weight of gypsum, the fluidity of the gypsum composition will decrease and the molding workability will deteriorate.

説明する。Furthermore, if the amount exceeds 100 parts by weight, it is difficult to expect to obtain a high-strength inorganic fiber-reinforced gypsum product, so the amount of water blended is preferably in the range of 30 to 100 parts by weight per 10 parts by weight of gypsum. The present invention will be specifically described below with reference to Examples and Comparative Examples.

The sample was injected into a mold, and after completely curing, the mold was removed and the bending strength was measured. The results are shown in Table 1. Further, as a comparative example, a composition containing no water glass and/or silicate was molded under exactly the same conditions as in Example 1, and the bending strength of the molded product obtained is also shown in Table 1. As is clear from Table 1, the molded products of example sample numbers 1 to 11 using β-type hemihydrate gypsum are:
It can be seen that the bending strength is significantly greater than the molded products of comparative sample numbers 1 to 3, which do not contain water glass and/or silicates other than sodium silicate.

It can be seen that the bending strength is high. Example 2 5 parts by weight of water glass, 5 parts by weight of calcium silicate and 70 parts by weight of water are mixed with 10 parts by weight of β-type hemihydrate gypsum and mixed well to prepare a gypsum slurry.
