Abstract
The invention relates to the field of viaduct bridge equipment, in particular to a sound-proof wall with photocatalysis self-cleaning performance for a viaduct bridge, which mainly comprises a sound-proof wall body, a sound-proof wall top, a light-emitting diode (LED) ultraviolet lamp, a protective layer and a photocatalyst coating. Due to the fact that the photocatalyst coating can oxidative-decompose various organic compounds and partial inorganic compounds, a protective layer without damaging effect on an outer wall of the sound-proof wall is spray-coated first, and then the optical contact agent coating is spray-coated. A layer of nanometer film is formed after TiO2 photocatalyst is spray-coated on the surface of a base material of the sound-proof wall, active oxygen and hydroxyl radical are generated under irradiation of sunlight ultraviolet and can decompose pollutant such as greasy dirt and germs attached to the sound-proof wall into carbon dioxide and water strongly, attachment of dirt and dust to the surface is greatly reduced, the sound-proof wall has a cleaning effect and can decompose ethylene generated by fresh fruit, reduces content of the ethylene in a warehouse, and fresh-keeping time of the fresh fruit is prolonged.
Description
Technical field
The present invention relates to the viaduct apparatus field, is a kind of sound proof panel with viaduct of catalytic self-cleaning performance concretely.
Background technology
Along with improving constantly of industry, the quantity of automobile is also constantly increasing, and the quantity of corresponding viaduct is also constantly increasing, and the cleaning of viaduct sound proof panel becomes the focus that people pay close attention to.At present, the cleaning of viaduct mainly adopts artificial the cleaning, not only waste of manpower resource, and bring the Personal Risk to people.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide the sound proof panel of viaduct with catalytic self-cleaning performance.
For realizing above-mentioned purpose; The technical solution that the present invention adopted has the sound proof panel of the viaduct of catalytic self-cleaning performance; It mainly comprises soundproof wall body, sound proof panel top, LED ultraviolet lamp, topping and photocatalyst coating, it is characterized in that: the first spraying protective layer of said playback wall body, spraying photocatalyst coating on topping then; Said topping is the titanium dioxide amorphous material; Said photocatalyst coating is the mixture of nano level titanium dioxide and silica, and the diameter of titanium dioxide and silica is the 3-9 nanometer, and playback wall top is provided with the LED ultraviolet lamp.
Said sound proof panel and topping and photocatalyst coating constitute an integral body.
Because the photocatalyst coating can the various organic compounds of oxidation Decomposition and part inorganic matter, so spraying earlier and then sprays the photocatalyst coating to the topping of its no destruction on the sound proof panel outer wall.The substrate surface spraying TiO of sound proof panel
2Form one deck nano thin-film behind the photocatalyst; Under the irradiation of solar ultraviolet, produce active oxygen and hydroxyl free radical; Can will attach on it pollutant brute forces such as greasy dirt, bacterium resolve into carbon dioxide and water, greatly reduce the dirt dust to the adhering to of surface, play clean effect.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the sectional drawing of soundproof wall body.
The specific embodiment
Fig. 1, Reference numeral shown in Figure 2 are following: soundproof wall body 1, sound proof panel top 2, topping 3, photocatalyst coating 4, LED ultraviolet lamp 5.
In the sketch map of the sound proof panel of Fig. 1, the viaduct with catalytic self-cleaning performance shown in Figure 2; It mainly comprises soundproof wall body 1, sound proof panel top 2, LED ultraviolet lamp 5, topping 3 and photocatalyst coating 4, it is characterized in that: said playback wall body 1 first spraying protective layer 3, spraying photocatalyst coating 4 on topping 3 then; Said topping 3 is the titanium dioxide amorphous material; Said photocatalyst coating 4 is the mixture of nano level titanium dioxide and silica, and the diameter of titanium dioxide and silica is the 3-9 nanometer, and playback wall top 2 is provided with LED ultraviolet lamp 5.
