た。However, although the water-absorbent polymer has a large water-absorbing ability, the water-absorbing polymer has a remarkably low rate of releasing water, so that, for example, by mixing this water-absorbing polymer with an appropriate paint, it is possible to obtain a plate-like material. Even if you paint on things,
It is difficult to make the plate-like material exert a humidity control function. On the other hand, the latter clay mineral has water absorbability as a simple substance, but since it has a small ability to take in moisture, it is rarely used as a desiccant or the like, and when mixed with water, it becomes colloidal. Therefore, when a large amount of clay mineral is added to and mixed with other materials, it is difficult to disperse.

The cations of the inorganic salt enter and the clay mineral aggregates in a swollen state. Then, even if a large amount of water is mixed and the water is brought into contact with the clay mineral, the clay mineral does not swell and diffuse. When this agglomerated aqueous solution of clay minerals is sprayed into a high-temperature atmosphere by a spray-drying method or the like, fine mist-like particles dry and solidify during the fall, and a powdery form in which an inorganic salt is adsorbed between layers. It becomes a clay mineral.

倍から数十倍である。The mixing ratio of clay mineral, inorganic salt and groove is as follows: clay mineral: inorganic salt: water = 100: 2 to 15:30 to 500
And That is, the mixing amount of the inorganic salt is the above-mentioned layered clay mineral 1
It is preferably within the range of 2 to 15 parts by weight with respect to 00 parts by weight, and if added in an amount greater than this, it will be liberated, which is not preferable. On the other hand, the amount of water may be such that the inorganic salt is dissolved and the clay mineral can be kneaded, and in order to facilitate the kneading, several to several times the total weight of the clay mineral and the inorganic salt is required. It is ten times.

よい。When the clay mineral and the inorganic salt are mixed with water, it is preferable to dissolve the inorganic salt in water and then add the clay mineral, because the cation of the inorganic salt easily enters between the layers of the clay mineral. The inorganic salt, the clay mineral, and water may be mixed at the same time, or the clay mineral may be added to water and then the inorganic salt may be added. In short, it may be determined according to the situation of the mixing apparatus.

る。As described above, when the clay mineral and the inorganic salt are added to water, mixed, and allowed to stand for 1 to 24 hours, the clay mineral precipitates and the volume of the precipitate decreases with the passage of time. It is presumed that this is because, after the clay mineral swells, the cations of the inorganic salt enter the clay mineral layers and the clay mineral aggregates in a swollen state. Then, the aqueous solution of the aggregated clay mineral is sprayed at 150 to 40 by a dry method.
When it is sprayed into a high temperature atmosphere of 0 ° C., the fine atomized particles that are discharged are dried and solidified during the fall, and a powder body having a diameter of several μ to 400 μ is formed by adsorbing an inorganic salt between layers. Become.
