を発揮する調湿セラミックス建材に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidified ceramic building material having a function of adjusting indoor humidity by being applied to a wall or the like inside a building.

【発明が解決しようとする課題】従来の技術で述べたも

険性がある。さらには森林資源の枯渇と地球環境保全上
の問題から今まで以上の使用は困難な状況にある。The above-mentioned prior art has the following problems. 1. Wood is a material having an excellent humidity control function, but is a combustible material, has poor dimensional stability, and has a risk of corrosion and insect damage. Furthermore, due to the depletion of forest resources and the problem of global environmental conservation, it is difficult to use them more than ever.

り、セラミックスに利用することは困難である。[0004] 2. The humidity control function of a humidity control building material using zeolite depends on the characteristics of zeolite and the amount thereof. Most of the zeolite has fine pores having a radius of 20 ° or less and is excellent in hygroscopicity, but poor in moisture release. In addition, the humidity control building material using zeolite is not a zeolite alone in the raw material, but mixes cement etc. as a hardening material,
Inevitably, the moisture absorption / release function, that is, the humidity control function is reduced. Furthermore, zeolite has difficulty in fire resistance due to its crystal structure, and is difficult to use for ceramics.

However, diatomaceous earth is mostly composed of macropores having a pore radius of 250 ° or more, and is excellent in water absorbency, but has a small humidity control function due to low hygroscopicity.

Although the humidity control function at 5 ° C. is shown, zeolite and diatomaceous earth are also shown as comparative materials as in FIG. This is the moisture absorption of each sample in which the relative humidity is repeatedly changed between 90% and 50% every 24 hours. If the difference between the moisture absorption at 90% humidity and the moisture absorption at 50% humidity is taken as the humidity control function, silica The shale has a moisture control function of 17% by weight, which is superior to that of 3% by weight of zeolite and 5% by weight of diatomaceous earth.

The change in moisture absorption and desorption at 5 ° C. is shown in the same manner as FIGS. 3 and 4 with zeolite and diatomaceous earth as comparative materials. This figure shows the time-dependent change of the moisture absorption rate of each sample under the condition of 90% relative humidity and the time-dependent change of the moisture absorption rate of the moisture-absorbed sample under the condition of 50% relative humidity. Siliceous shale absorbs moisture quickly under high humidity conditions, and the absorbed moisture quickly releases moisture under low humidity conditions.

しい。The firing temperature in the present invention is 600 to 11
00 ° C. The humidity control function of siliceous shale is firing temperature 700 ℃
The function hardly changes until the firing temperature increases. A firing temperature of 600 ° C. or higher is required in order to impart water resistance to the extent that it does not collapse into water. However, as the firing temperature increases, the humidity control function decreases. When the firing temperature is 1100 ° C. or higher, pores having a radius of 20 to 100 ° are sharply reduced by firing, and continuous pores are reduced, so that the humidity control function is hardly exhibited. 800-1000 ° C in order to express a greater humidity control function than wood and satisfy the strength and durability as a ceramic building material
It is appropriate to fire at a firing temperature of. (See FIG. 6) For the ceramic raw material to be mixed with the siliceous shale according to claim 2, various clays are used for the purpose of enhancing formability and strength. Various inorganic pigments are blended to diversify the design such as color tone and texture. Since the humidity control function depends on the blending amount of the pulverized siliceous shale and the firing temperature, it is desirable to mix the other ceramic raw materials as little as possible and to achieve the target material design at the lowest firing temperature.
