Experimental Example 2

Was irradiated for 250 hours with ultraviolet rays formed was coated with the coating composition prepared in Example 3 were measured the adhesion strength of the film after irradiation. As Example 3 Contact stomach pigment Sani匕 titanium in place of the titanium oxide photocatalyst in the formulation of Comparative Experiment (EP - 498, Dainichi Seika) coating composition manufactured by adjusting with (comparative coating composition) in a similar manner by irradiating ultraviolet rays to the formed film was measured the adhesion strength of the film after irradiation. Specifically, the experiment in the following manner.

Put coating composition or comparative coating composition prepared in Example 3 in airless spray one, sidewalk plate (with primer first processing) spraying without Man逼 to (300 XI 50 X 5 Yuzuru) one side of the ventilation drying solidified by in film thickness 0 5 mm panel (specimen: the second sample by). was created. Been over 2 5 0 hours UV irradiation of (255 ± 45 w / m 2) using a sunshine © Ezameta (force one Bon'aku light type) for such panels each second sample. After UV irradiation, the method the same way of Experimental Example 2 (1) was tested according to the test (tensile strength) defined in JIS K5400-1990 8. 8, it was evaluated the adhesion of the coating. The results are shown in Table 9.

<Table 9>

As can be seen, the film formed by the coating composition (Example 3) of the present invention, despite containing 耀媒 active type titanium oxide with an organic resin, the adhesion strength is influenced by the ultraviolet ray irradiation adhering to the intensity received without underlying substrate (sidewalk plate). Without being bound, as this one reason, in the coating composition of the present invention (Example 3), the main component is slaked lime (calcium hydroxide) is over time of calcium carbonate Te cowpea to curing it is conceivable to firmly adhere the base sheet by. That is, the coating composition of the present invention, even if the resin in by the action of the photocatalyst is divided, is intended to mean that the adhesion strength to be practically required as a film can be sufficiently ensured. This is especially coating compositions of the present invention composed mainly of force Rushiumu compound having self-curing has the capability to secure the initial adhesion and adhesion construction even resin to be blended is no less in as long as it is intended to suggest the Yoiko.

Further, the surface of the formed by coating composition containing the photocatalyst activated Sani匕 titanium (Example 3) coating is likewise plaster unique and the coating composition not blended photocatalytic activity type titanium oxide (Comparative Example) has a texture, even change after UV irradiation (alteration, discoloration) is not observed, it was confirmed that has excellent weather resistance.

KoTsuta 6 specimens used humidity test such panels. Incidentally, the side surface of the panel to properly evaluate the humidity conditioning of the coating layer and the back surface (non-coated surface coating composition) moisture-proof sheet - subjected to Le water vapor was prevented from being transmitted. Specifically, the building material panels of the present invention was allowed to stand under an environment of a relative humidity of 6 5% Temperature 2, and 枰量 after 48 hours 7 minutes absorption amount is reached almost equilibrium, then the relative humidity of the subject 9 8% temperature 2 0 and transferred to an environment of ° C, was determined water absorption of the panel per unit surface area (1 m 2) was枰量after 48 hours again reaches near equilibrium moisture absorption rate . Then transferred to sample after the moisture absorption test likewise relative to an environment of humidity of 6 5% Temperature 2, 2 and 4 hours抨量after standing calculated moisture absorption of the panels per unit surface area (lm 2) and It was. Then, to evaluate the difference in moisture absorption in these experiments as the respective moisture absorption and desorption amount.

Results together with humidity effect of Vinyl Wallpaper chloride (vertical 4 0 c mX ® co 2 5 cm) which was used as comparative products are shown in Table 1 0.

<Table 1 0>

It should be noted that the display in the table means the following.

20 ° C65% by weight (g / m 2) ": 20 ° C65¾RH per 1 m 2 for 48 hours after being left heavy

20 ° C65¾S * (g / m 2) * 2: Weight per 1 in 2 after being left for 20 ° C65% RH 24 hours. "

Weight per 1 m 2 of 20 ° C98% by weight (g / m 2) 20 ° C98¾RH 48 hours after standing

Hygroscopic (g / m 2) 20 ° C98% by weight - 20 ° C65% by weight "

Moisture release (g / m 2) 20 ° C98% by weight - 20 ° C65% by weight * 2

Therefore, coating compositions excellent humidity function in the film formed by coating (hygroscopicity, release) of the present invention is confirmed that there is, Ru useful der to prevent condensation of the chamber wall It was considered.

(2) the absorption rate of carbon dioxide in Table 1 2, also shown in FIG. 7 changes over time in the concentration of carbon dioxide.

Ku Table 1 2> Therefore, the coating composition of the present invention: coating film formed by (main component slaked lime) is about 80% carbon dioxide in the atmosphere (initial concentration of 4 2%) in 4 hours, 100% for 25 hours absorbed was found to be immobilized as calcium carbonate.

Performance Evaluation of Example 5 photocatalyst (Nyuomikuronkai removability)

Using coating compositions prepared in Example 3, the film thickness in the same manner as in Experimental Example 3, respectively 0 3 mm of the panel. (5 cmX 1 5 cm, area coverage: 0. 0075m 2) (test body) create and examined the NO x removal capability of the panel is formed a coating (coating film). Incidentally, the sides and back of the panel to the same manner as the actual Kenrei 3 appreciate the NO x removal capability of the coating layer was coated with the seal. For the measurement of the NO X removal capability, potentiostatic automatic measuring instrument of the electrolysis method: The (NO sensor Shinkosumosudenki Co.) was used (COSMOS DENSER TECHNOLOGY P. 85 (1997) specifically, Osaka Sangyo technology Research Institute reported in accordance with (Νο. 14 (2000) p. 76-81), was carried out as follows (see Figure 8).

The ① specimen is set to the photocatalytic reaction vessel.

② bypass side (--C2 between) the test gas was allowed to flow through the (NO, N_〇 2), changed to the reaction system side flows into the test gas into the reaction system with the photocatalyst reaction vessel, reaction system NO and NO 2 gas concentration in the inner measured in NO and NO 2 sensor of the measuring unit. The output value of ③ NO sensor at the stage of saturation, irradiating black light.

③ After the predetermined time, it stops the irradiation of black light.

The results of measurement of NO and NO 2 gas concentration in the reaction system (ppm) shown in FIG. In the figure, ※ is the start of the test gas flowing into the reaction system, ON the irradiation starts, and 〇 FF of black light indicates the irradiation stop black light. Note the horizontal axis represents time (minutes) was set irradiation starting black La site as 0 minutes. The reaction container in the flows of the test gas into the reaction system proceeds substitutions from the state NO (N0 2) No, the output of NO and N_〇 2 sensor became gradually raised state close to saturation. However, as shown in FIG. 9, it takes a considerable time to NO and N 0 2 saturated, it was found that the specimen (film) itself of the present invention there is NO and NO 2 adsorption capacity. Further, since the reduction of the NO concentration Hence the reaction system to the irradiation of black light is (0. 77Roropai1) was observed, the test of the present invention (coating) is confirmed to be reliably exhibit the NO removal capability It has been. Although more is in either N 0 2 concentration II was found to decrease significantly. Therefore, the present specimen has no release of N0 2, that also has NO 2 resolution Conversely was confirmed.

Further, by using the coating composition of Example 4 was half the amount of the titanium oxide photocatalyst, when having conducted the same experiment, NO and N0 2 resolution in accordance with the reduction of the amount of the titanium oxide photocatalyst was reduced although, in the same manner as described above significantly NO and N0 2 decomposition removal effect was confirmed.

These results, coating film formed by the composition of the present invention, defer rather is based on the porosity of the coating is porous and formed of itself calcium compound, contaminants such as N Ox surface- it captures attracted over internal and front surface and contaminants are trapped inside of the coating was found to be decomposed efficiently and reliably by the action of the photocatalyst scattered inside not only the coating surface (non-machine oxides). In particular, fouling properties of the coating of dyeing the adsorbed capture, imply a good degradation cycle efficiency that leave accumulate contaminants during light non-irradiation of the night or the like, it when light irradiation day secondary decomposition removed it is. Furthermore, the nature of the coating of contaminants can be adsorbed held to the inside as well as the coating surface is to have a effect of increasing the contact area between the contaminant and the photocatalyst, as a result, the photocatalytic (inorganic oxides as in the present invention even things)-contained coating composition is intended to mean that can exhibit good photocatalytic activity efficiency with a small amount.
