性炭の分解が起こり得るという問題もある。On the other hand, in the latter case of a composite of activated carbon and a photocatalyst, the deodorizing performance is determined by the adsorption performance of the activated carbon, and there is a problem that the purification performance of ammonia, hydrogen sulfide, acetaldehyde, etc., which is difficult to adsorb on the activated carbon, is not good. . Further, there is a problem that the deodorizing performance is deteriorated by absorbing moisture in a high humidity atmosphere. Further, since the photocatalyst and the activated carbon cannot be made into a paint, the photocatalyst is baked on the activated carbon formed into a honeycomb shape or the like, but there is a problem that the activated carbon is ignited depending on the baking conditions and the activated carbon may be decomposed by the photocatalyst.

The odor component of is adsorbed on the film and the air is purified. The adsorbed odor component is decomposed by ultraviolet irradiation, and the purification performance of the paint is regenerated. Since the adsorbent of the air-purifying coating material of the present invention is hydrophobic, the purification performance is not significantly deteriorated due to moisture absorption even in a high humidity atmosphere. Further, the adsorbent is more chemically stable than activated carbon, is not decomposed by the photocatalyst, and has no risk of ignition.

Make powder so that it becomes 6, 92, 430, and this powder 4g
After purging clean air in a 27 liter closed box, distilled water is evaporated to a high humidity atmosphere of 95% RH or more, and ammonia is evaporated in 100 pp.
These adsorption performances were measured by setting the initial concentration to m, circulating the powder by ventilation, and measuring the change in concentration with a gas sensor. FIG. 1 is a graph showing the result. It is said that the higher the silica / alumina ratio is, the more the hydrophobicity is improved. However, the adsorption performance is conversely deteriorated at 430, and the silica / alumina ratio may be 92 or less.

In order to see the adsorption performance for these various odorous components, various gases were generated in a dry atmosphere by the same method as above, and the adsorption performance was measured.

5. Palladium ion exchange ZSM5 has excellent adsorption performance for most odors. If the ion exchange rate is 1% or more by weight, the adsorption performance will be equal to or superior to that of activated carbon for any odor. In FIG. 5, it can be seen that when the weight ratio of the copper ion-exchange ZSM5 is changed from 0.5% to 1%, the adsorption performance is improved and becomes almost equal to that of activated carbon.

Acetaldehyde was injected to make the initial concentration 100 ppm, and the deodorizing performance was measured by a gas sensor with and without irradiation of one 6W black light while circulating by blowing air. FIG. 10 shows the result. Until the adsorbed amount is saturated, the deodorization rate is faster when the photocatalyst and zeolite are mixed than when the photocatalyst is used alone. Further, in the deodorizing performance after adsorption saturation, if the blending weight ratio of the photocatalyst during film formation is less than 15%, the decomposition rate becomes extremely slow and sufficient deodorizing performance cannot be obtained. If it is 15% or more, it is decomposed even after adsorption saturation, and sufficient deodorizing performance is obtained.

By using the high silica synthetic zeolite H-type ZSM5 having a silica / alumina ratio of 56 or more and 92 or less as the adsorbent, the adsorbent is hydrophobic, so that the purification performance is less deteriorated even in a high humidity atmosphere. Further, the high-silica synthetic zeolite H type ZSM5 is chemically more stable than activated carbon, is not decomposed by a photocatalyst, and has no risk of ignition.
Also, because it is made into a paint, it has a high degree of freedom in use,
Very easy to handle.
