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.

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. Building materials are required.
この様な事情から、種々の無機質建材が検討されており

せ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 strengthen gypsum with various fiber materials, but it is said that it cannot be expected to improve the strength of the plaster because of the poor adhesion between the gypsum and the fiber materials. There are problems.

Methods of reinforcing with various fiber materials are known, but they have the problem that the materials are expensive because they contain expensive polymers. In order to solve these problems, the present inventors conducted intensive studies and found that a composition containing water glass and ferrosilicon in gypsum has good adhesion to inorganic fiber materials. We discovered that by reinforcing objects with inorganic fibers, especially glass fibers, we could obtain inorganic fiber-reinforced gypsum products with extremely high strength, which was not possible before.
This led to the present invention.

て高強度の無機質繊維強化石膏製品が得られる。Examples of the gypsum used in the present invention include Q-type hemihydrate gypsum and B-type hemihydrate gypsum. These plasters can be used alone or in combination. Water glass and ferrosilicon, which are the constituent parts of the present invention, work to improve the adhesion between the gypsum composition and inorganic fibers by blending these two components into plaster. By reinforcing the gypsum composition with inorganic fibers, especially glass fibers, extremely high strength inorganic fiber reinforced gypsum products can be obtained.

具体的に説明する。Among these inorganic fibers, those that have particularly good adhesion to the plaster composition and have a high reinforcing effect are glass fibers.
．． If it is less than 1 part by weight, it is difficult to expect to obtain an extremely high-strength inorganic fiber reinforced gypsum product, and if it is more than 3 parts by weight, the fluidity of the gypsum composition will not only deteriorate, but also the molding workability will deteriorate. Since the dispersion state of the inorganic fibers becomes poor and the strength tends to decrease, the blending amount of the inorganic fibers is preferably in the range of 0.1 to 3 parts by weight per 10 parts by weight of gypsum. The amount of water used in the present invention is
When the amount is less than 3 parts by weight per 100 parts by weight of gypsum, the fluidity of the gypsum composition decreases and molding workability deteriorates. Furthermore, if the amount is more than 10 parts by weight, it is not possible to obtain a high-strength inorganic fiber-reinforced gypsum product, so the amount of water added 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 explained below using Examples and Comparative Examples.

The mixture was injected into a mold and removed from the mold after complete hardening, 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 ferrosilicon 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. Table 1 Blending ratio of gypsum composition and bending strength Glass fiber: FES-13-09
02A (Fuji Fiber Class Co., Ltd. product) As is clear from Table 1, the molded products of example sample numbers 1 to 9 using B-type hemihydrate gypsum do not contain water glass and/or ferrosilicon. It can be seen that the bending strength of the large medium is greater than that of the molded products of Comparative Example Sample Nos. 1 to 3.

It can be seen that is large. Example 2 10 parts by weight of B-type hemihydrate gypsum, 5 parts by weight of ferrosilicon, and 7 parts by weight of water are blended and stirred well to prepare a stone pipe slurry.
