Description of the Related Art It has been pointed out that, in the event of a disaster such as an earthquake, the damage of an aged wooden house was much greater than that of other buildings. This is one of the causes of the deterioration of the wall material due to the deterioration of the wall material, which causes the decay fungi to propagate due to the dew condensation inside the wall material. This is closely related to the climate of Japan, and the high temperature and high humidity in the summer causes humidity to cause bad odors on walls and wood and bacterial growth. In winter, the humidity in the house is low, but due to the high airtightness of houses and the widespread use of heaters, internal dew condensation is induced due to the decrease in temperature at night, which causes deterioration of wall materials. Such a tendency is particularly remarkable in the case of indentation and storage where the atmospheric mobility is low. In order to prevent the growth of bacteria due to such humidity and the damage due to the deterioration of wall materials, quick lime, calcium chloride, silica gel, etc. are conventionally used as a desiccant, and indoor dehumidification is performed by a dehumidifier. Further, a zeolite-based building material (Japanese Patent Laid-Open No. 3-93662) has been developed as a humidity control building material.

Further, the moisture absorption effective period of the reagent is short, and once the saturation point is reached, the moisture absorption function is significantly deteriorated. Zeolite has excellent hygroscopicity, but is not suitable as a humidity control material because it has poor hygroscopicity. Dehumidification with a dehumidifier has energy problems, and at the same time, it may adversely affect the health because it lowers the humidity in the environment more than necessary. Further, JP-A-3-109244 and the like do not pay attention to the pore size distribution and do not have an excellent autonomous humidity control function. Further, Japanese Patent Laid-Open No. 5-
Although 302781 and the like use a pore diameter of 15.5 nm, it does not have a function of controlling humidity automatically because it does not control pores of 2 to 6 nm.

The reagent for making the solution acidic or alkaline may be hydrochloric acid, nitric acid, sulfuric acid, or sodium hydroxide or potassium hydroxide. The obtained product is washed as it is or with distilled water several times and dried. The drying conditions are not particularly limited, but the temperature is 60 at normal pressure.
It can be performed at about 100 ° C. After the completion of drying, in order to remove the organic template, extraction and removal with an organic solvent such as methanol, ethanol, acetone, toluene, xylene and benzene at a temperature of 200 ° C or lower for 3 hours or more, or 500 to 1000 ° C in air, holding time The autonomous humidity control material of the present invention can be obtained by performing the heat treatment for 4 to 10 hours. Further, a surfactant having a long-chain alkyl group, an alcohol, an ether, or an ester derivative is arbitrarily selected as an organic material template, and the surrounding is surrounded by a silicon compound or a transition metal compound, and then polymerized, baked or extracted to remove the template. By doing so, those having an average value of pore diameters in the range of 2 to 6 nm can be obtained. This pore diameter was measured by measuring the pore diameter distribution at the temperature of liquid nitrogen. In the present invention, the term “synthesized using a surfactant or an organic substance having a long-chain alkyl group as a template” means that it is synthesized by the above process.
