Description of the Related Art In recent years, in response to a request for improvement of a cityscape, as a means of beautifying a road structure, a scenic countermeasure such as painting the road structure has been taken. However, even if such a coating is applied, these coating surfaces are contaminated by automobile exhaust gas, dust in the air, acid rain, etc. under the use environment, and this contamination adheres to the road structure over time, Moreover, maintenance cannot be easily performed in some places, resulting in a loss of scenery and aesthetics.

It is supposed to be dirty. In the method specified in JIS-L-1023, most of the constituents of the contaminated material are sand. Therefore, none of the above test methods considers exhaust gas of automobiles, tire scraps, etc. as polluting materials, and evaluates and confirms the pollution resistance of structures installed outdoors such as road structures.

た。As a method other than JIS for confirming the stain resistance of the coating film surface, there is the Building Material Testing Center Standard (JSTM). This building material test center standard is intended for outdoor stains and uses yellow ocher as a pollutant,
A composition comprising 3 kinds of test dust (having silica sand as a main component), 8 kinds of test dust (calcined Kanto loam) and carbon black is used. However, regarding this test method, it is difficult to obtain a constantly stable composition because the composition of yellow ocher varies greatly from lot to lot, and it is also difficult to obtain oil that is contained in exhaust gas of automobiles, freezing of concrete and roads. No consideration was given to the calcium content contained in the inhibitor.

明度差により調べた。A contamination test using the examples of the composition for contamination test of the present invention was conducted as follows. That is, 50% by weight of the composition for contamination test and 50% by weight of distilled water
Was mixed to prepare a contaminated suspension, and the contaminated suspension was applied to the coating surface of a coated plate as a test piece to contaminate it, and then the contaminated surface was dried. Drying was carried out by leaving at 50 ° C. for 24 hours, then at 80 ° C. for 8 hours, and at room temperature for 16 hours. Then, tap water was applied to the contaminated surface to wash the dirt to some extent, and then the dirt was wiped off with a wet Kimwipe, and after drying, the stain recovery property of the contaminated surface was examined by color difference and brightness difference.

た。As shown in Table 2, in the JIS test method,
Whether it is an inorganic paint surface or a fluororesin paint surface, both color difference and brightness difference are low, and both can be said to have excellent stain recovery properties. In the above test, the surface of the fluororesin paint has a poorer stain recovery property than the surface of the inorganic paint. Compared to the inorganic paint surface, the surface of the fluororesin paint is more likely to have raindrops and the like, and it has been found that dirt cannot be easily removed in an actual exposure test in the vicinity of the road. Therefore, according to the JIS test method, The actual pollution around the road was not reproduced, and the stain recovery property difference which could not be found by the JIS test method was not found by the stain test composition of the present invention and the stain test method using the composition. It was discovered that it was a reproduction of actual pollution around the road.
