果がないものであった。The above conventional sound absorbing panel as described above can be installed at a place where it emits noise due to the running of a vehicle or the like, so that a reasonable noise pollution can be reduced. In addition, as pollution caused by running of vehicles and the like, it has been pointed out that there is a problem of environmental pollution due to nitrogen oxides (NOx) contained in exhaust gas discharged from automobiles, especially diesel automobiles. This NOx is said to induce respiratory disorders in the human body, and generates oxidants in association with solar ultraviolet rays and hydrocarbons, causing so-called photochemical smog. However, as described above, the conventional sound-absorbing panel is intended only to reduce noise pollution, and has no effect on environmental pollution by NOx.

When a plurality of soundproofing panels are stacked, air holes are formed in the upper surface plate and the lower surface plate of each soundproofing panel, and when the soundproofing panels are stacked, the ventilation holes are communicated so that air can pass between them. do it. In the case where a ventilation hole is formed in the upper plate, it is preferable to prevent the rainwater from entering through the ventilation hole with an eave or the like.
Further, in order to prevent sound leakage from the vent, the size of the vent is preferably about 5 to 50 cm 2.

塗膜を形成するのが好ましい。In general, an aluminum alloy, a synthetic resin, or the like is used for the soundproofing panel to reduce the weight. However, when a cementitious coating film containing a photocatalyst is formed on a front plate made of aluminum, It is preferable to use alumite that has been subjected to anodized unsealing treatment, and to form a cementitious coating film containing a photocatalyst on the surface of the anodized aluminum that has not been sealed.

Because there are many micropores because it is unsealed,
This is because the anchor effect improves the adhesiveness of the cementitious coating film, and since the surface of aluminum that has not been sealed with alumite is porous, a cementitious coating containing a photocatalyst formed thereon is formed. This is because the film has a large contact area in contact with air, that is, NOx and the like, and NOx and the like are removed very effectively.

In the case of a metal material, it is preferably formed of aluminum in order to reduce the weight. This aluminum is treated as a non-anodized surface of alumite, and if a cementitious coating film 9 containing a photocatalyst is formed on the non-sealed surface of the alumite, the adhesion is improved, and the contact area in contact with air, that is, NOx, etc. And NOx and the like are removed very effectively.

It is preferably formed in the range of μm. If it is less than 10 μm, the amount of the photocatalyst is small and the effect of removing NOx and the like is poor, and if it exceeds 1000 μm, the film becomes too thick, and when the film is formed, the coating film cracks and it is difficult to obtain a good coating film.
