Abstract
The invention relates to a photocatalyst building outer wall with antifouling and self-cleaning functions, which is characterized in that a photocatalyst material is coated on the building outer wall, so that the building outer wall has antifouling and self-cleaning functions. The photocatalyst building outer wall with the antifouling and self-cleaning functions belongs to the field of air purification. A protective layer is firstly sprayed on the building outer wall, and a photocatalyst layer is then sprayed on the protective layer. A layer of nanometer film is formed after TiO2 photocatalyst is sprayed on the surface of a base material of a building, and active oxygen and hydroxyl radical are generated under the irradiation of sunlight ultraviolet rays, so that attached pollutants such as greasy dirt and bacteria can be decomposed into carbon dioxide and water forcedly, and the attachment of dirt dust to a surface is greatly reduced.
Description
Technical fieldMake the building outer wall that the photocatalyst building outer wall with anti-fouling and self-cleaning function of anti-fouling and self-cleaning function arranged thereby the present invention relates to apply on a kind of outside the building wall photocatalyst material, belong to air purification field.
Background technologyBecause atmosphere pollution, airborne oil content, sand and dust etc. cause serious surface attachment floating dust to building and civic landscape sculpture, curtain wall, advertisement plate, speedway sound-proof wall etc., directly affect the attractive in appearance of building.In addition, the surface of outdoor architecture thing can suffer ultraviolet irradiation, thereby quickens its surperficial ageing process.At present; Be used for common the having of method of control atmosphere pollution: kind value trees; Reduce the exhaust emissions of motor vehicles; Building outer wall and glass are cleaned etc., but with upper type to the purification of atmosphere and urban environment to improve effect undesirable and manpower, financial resources cost are bigger, it is also slow to take effect.
Summary of the inventionIn view of the defective that prior art exists, the purpose of this invention is to provide a kind of can beautifying urban environment and the photocatalyst building outer wall with anti-fouling and self-cleaning function of control atmosphere pollution.
For realizing above-mentioned purpose, the technical solution that the present invention adopted mainly comprises building outer wall, topping and photocatalyst coating.The first spraying protective layer of said building outer wall, spraying photocatalyst coating on topping then.Said photocatalyst coating is by TiO
2Particle constitutes, said TiO
2Its diameter of particle is less than 7nm.
Because the photocatalyst coating can the various organic compounds of oxidation Decomposition and part inorganic matter, thus outside the building on the wall spraying earlier the topping of its no destruction and then is sprayed the photocatalyst coating.The substrate surface spraying TiO of building
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 dirt dust adhering to the surface; Has superpower hydrophily; Approach 0 ° with the contact angle of water, water can be scattered in the surface equably and form moisture film, reaches cleaned base material; Can make the brand-new state of the permanent maintenance of building thing, the photocatalyst technology has greatly been saved the cleaning charge of building outer wall and glass and has been used.Because the high-hydrophilic of photocatalyst coating can form antifogging coating, because its powerful decomposition can be divided the greasy dirt of taking off the surface, keep self cleaning simultaneously simultaneously.Because photocatalyst of titanium dioxide has the ultraviolet characteristic of absorption, can make coated surface exempt from ultraviolet aging action again, prolong the application life of coated surface greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a photocatalyst coating microstructure sketch map of the present invention.
The specific embodiment
Fig. 1 is following to Reference numeral shown in Figure 2: building outer wall 1, topping 2, photocatalyst coating 3, TiO
2Particle 4.
In the photocatalyst building outer wall sketch map with anti-fouling and self-cleaning function illustrated in figures 1 and 2, it mainly comprises building outer wall 1, topping 2 and photocatalyst coating 3.Said building outer wall 1 first spraying protective layer 2, spraying photocatalyst coating 3 on topping 2 then.Said photocatalyst coating 3 is by TiO
2Particle 4 constitutes said TiO
2Particle 4 its diameters are less than 7nm.
