Abstract

PROBLEM TO BE SOLVED: To provide a self-cleaning type translucent sound insulating wall in which contaminant stuck to a sound insulating plate can be washed away without requiring man-power and see-through performance of a translucent plate can be maintained for a long term. SOLUTION: This translucent sound insulating wall using a translucent plate 3 as a sound insulating plate 2 is formed with a hydrophilized film 4 by activating titanium dioxide as an optical catalyst on the surface of the translucent plate 3. Hereby, even if contaminant such as dust or exhaust gas of a vehicle is stuck onto the surface of the translucent plate 3, the contaminant is decomposed by strong oxidizing force of the activated titanium dioxide and further the surface made hydrophilic, water is introduced between the contaminant stuck to the surface and the surface to float up the contaminant, and hence the contaminant hardly sticks to the surface and is easily washed away by rainfall or the like even in the case of sticking. Accordingly, the contaminat hardly sticks to it, and the see-through performance of the translucent plate 3 is maintained in the good condition for a long term.

2. Description of the Related Art Sound insulation plates are installed along roads and railways for the purpose of isolating noise from vehicles. Some of these sound insulation plates are formed from opaque plates such as PC concrete and metal, but those formed from opaque plates have excellent sound insulation properties, but the opacity obstructs the surrounding scenery, resulting in a feeling of oppression. Yes, and the landscape is poor. Therefore, in recent years, a sound insulation plate made of a light-transmitting plate having a light-transmitting property has been installed along roads and railways in order to provide a wealth of see-through performance.

However, since the sound insulating plate is installed on the road and is constantly exposed to the exhaust gas and dust of the vehicle, the exhaust gas and dust and the like adhere to the sound insulating plate unless they are cleaned occasionally. When the sound insulation plate is made of a light-transmitting plate, there is a problem that the see-through performance is significantly reduced. However, cleaning by hand is not only troublesome and troublesome, but also the cleaning can be performed on the road side by using a device such as an overhang on the opposite side of the road, using a device such as an overhang to outside the sound insulating wall. I had to. Therefore, the applicant of the present invention has reported that
As described in Japanese Patent Application Publication No. 4 (1994), there has been proposed a soundproof wall in which a light-transmitting plate is rotatably mounted on a rotating shaft and the opposite side to the road can be washed from the road side by appropriately rotating the light-transmitting plate. However, the cleaning was laborious and laborious because it was still manual.

According to the present invention, since a film that has been made hydrophilic by activating titanium dioxide as a photocatalyst is formed on the surface of the light-transmitting plate, contaminants such as dust and vehicle exhaust gas are permeable. Even if it adheres to the surface of the light plate, the strong oxidizing power of the activated titanium dioxide decomposes the contaminants, and the hydrophilicized surface causes water between the contaminants adhering to the surface and the surface. It is difficult to adhere because it interrupts and floats contaminants, and even if it adheres, it is easily washed away by rain etc. and removed, so it is difficult for contaminants to adhere, and the translucency of the translucent plate in good condition for a long time Can be maintained.

Titanium dioxide as a photocatalyst may be of rutile type, but is preferably of anatase type because of its high activity. This titanium dioxide has a wavelength range of 300 to 400 nm.
m is activated by irradiating ultraviolet light around m. The activation causes a strong oxidizing power to be developed, contaminants attached to the surface are decomposed, and the activation causes the surface to have a contact angle with water. Hydrophilization is performed to about 0 to about 20 degrees, and contaminants are less likely to adhere due to the hydrophilicity, and even if they adhere, they can be easily washed away by rainfall or the like.

The coating 4 containing titanium dioxide as a photocatalyst may be formed directly on the light transmitting plate 3. However, when the light transmitting plate 3 is formed of a synthetic resin plate such as polycarbonate, the light transmitting plate 3 is not used. If an undercoat layer 6 made of a silicone-based paint that is not easily attacked by the strong oxidizing power due to the activity of titanium dioxide due to the siloxane bond between the film 3 and the coating 4 is formed, the light-transmitting plate 3 is activated by the activation of titanium dioxide. When the silicone-based compound is used as the binder for the coating 4 containing titanium dioxide as a photocatalyst, the undercoating layer 6 and the coating 4 become the same type of coating. Can be adhered to.
