In addition, there is a problem that in a high-humidity atmosphere, moisture is absorbed and deodorization performance is reduced.

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 therein to 100 pp.
The adsorbing performance was measured by setting the initial concentration of m, circulating the powder through ventilation, and measuring the change in concentration with a gas sensor. FIG. 1 is a graph showing the results. It is said that the higher the silica / alumina ratio, the higher the hydrophobicity. However, in the case of 430, the adsorption performance is reduced, and the silica / alumina ratio may be 92 or less.

If the ion exchange rate is 1% or more by weight, the adsorption performance is equal to or exceeds 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 equivalent to activated carbon.

を行ってサンプルを作成した。Titanium oxide ST-01 (trade name, manufactured by Ishihara Works Co., Ltd.) was used as a photocatalyst, and high silica synthetic zeolite H type ZSM5 having a silica / alumina ratio of 90 and 1% by weight of copper ion exchanged was used as an adsorbent.

能は得られる。Each of the four samples was placed in a 27-liter box and purged with dry clean air.
Acetaldehyde was injected to give an initial concentration of 100 ppm, and the air sensor was used to measure the deodorization performance with and without irradiation of a single 6 W black light while circulating by blowing air. FIG. 10 shows the result. Until the adsorption amount is saturated, the deodorizing speed is higher when the photocatalyst and the zeolite are mixed than when the photocatalyst alone is used. Further, in the deodorizing performance after the adsorption saturation, if the blending weight ratio of the photocatalyst at the time of 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 can be obtained.

No deodorizing performance was obtained, and the coating amount could not be as thick as 12 (mg / cm 2 ) or more.

ようになる。 As described above, according to the present invention,
By using 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 reduced even in a high humidity atmosphere. In addition, the high silica synthetic zeolite H-type ZSM5 is more chemically stable than activated carbon, does not decompose with a photocatalyst, and has no danger of ignition.
In addition, by using paint, the degree of freedom during use is high,
Very easy to handle. Further, when the film is formed,
By increasing the mixing ratio of the medium to 15% by weight or more,
To be able to obtain sufficient playback ability even with black light
And the regeneration efficiency becomes sufficient. In addition,
The main component is colloidal silica.
This makes it easier for ultraviolet light to pass through the binder,
Ultraviolet light is easily absorbed by the catalyst, and it is porous.
UV light penetrates into the interior even if the coating is thick
