Abstract
The invention discloses a photocatalytic paint which comprises, by weight, 10 to 30 parts of nanometer titanium dioxide powder, 20 to 50 parts of resin and 2 to 10 parts of a diluent, wherein, the resin is one or more selected from the group consisting of acrylic resin, epoxy resin, polyurethane and styrene acrylic resin, and the diluent is water or ethanol. The photocatalytic paint further comprises a thickening agent and a dispersant, and the total amount of the thickening agent and the dispersant is 5 to 10 parts. The photocatalytic paint can be used in construction fields of furniture, floors, walls and the like; scientific and reasonable composition and ratio enable service performance of the paint to be improved and additional performance to be increased; the paint has strong action on sterilization, deodorization, air purification and the like because of existence titanium dioxide photocatalytic particles. Application of photocatalyst technology in the paint enables the paint to better perform the functions of environmental protection and environment improvement; the paint is widely applied in construction fields.
Description
Technical field
The present invention relates to building coating, specifically is a kind of photo-catalytic coating.
Background technology
Building industry now or public place be finishing material at home; Contain objectionable impuritiess such as a large amount of formaldehyde, benzene, YLENE, acetone; These materials will slowly volatilize in air at normal temperatures constantly; People's democratic meeting in such environment of being everlasting symptoms such as nose larynx piquant, eyes are shed tears, tired weak, amnesia that go out to lose face, Here it is so-called " mansion syndrome " and " chemical substance anaphylaxy ".But, not having good solution at present, people can only strengthen ventilation and use air clearing product to remove indoor atmospheric pollution, but these mode effects are unsatisfactory.Research shows; The photocatalyst of titanium dioxide particle of nano-scale can produce the change of physico-chemical property; What become is comparatively active, by the irradiation of faint light such as sunlight or light or even room fluorescent lights, to the photocatalyst of titanium dioxide particle luminous energy is provided; Can form electron-hole pair on its surface, in a single day airborne oxygen touch and will generate ultra-oxygen anion free radical O
2-, and in a single day the airborne water molecules of relative humidity touches the active hydrogen oxyradical OH that just generation has extremely strong oxygenizement
-, they can produce the redox effect with the carbon atom in the organic substance, thus various organic cpds of oxygenolysis and part inorganics destroy the cytolemma and the protein that solidifies virus of bacterium.But photocatalyst product is more at present, and great majority are to exist with gel form, is sprayed on the metope with the pore spray gun, form particulate state on its surface, but this mode poor activity can not obtain good photocatalysis.
Summary of the invention
The purpose of this invention is to provide a kind of use properties better, the photo-catalytic coating photochemical catalysis better effects if, environment-friendly type for building.
Technical scheme of the present invention is achieved in that a kind of photo-catalytic coating, and in parts by weight, it consists of: titanium dioxide powder 10-30 part, resin 20-50 part, thinner 2-10 part.
Said titanium dioxide powder is a nano level.
Said resin is one or more in vinyl resin, epoxy resin, urethane and the styrene-acrylic resin.
Said thinner is water or ethanol.
Also contain thickening material and dispersion agent in the said photo-catalytic coating, its total amount is 5-10 part.
Said thickening material is Natvosol or silicon-dioxide.
Said dispersion agent is ammonium ion type vinylformic acid dispersion agent or sodium-ion type vinylformic acid dispersion agent.
The preferred composition and the proportioning of said photo-catalytic coating are: titanium dioxide powder 15-25 part, resin 36-45 part, thinner 2-6 part, thickening material 2-3 part, dispersion agent 3-5 part.
The invention has the beneficial effects as follows: coating of the present invention can be applied to building fields such as furniture, floor, body of wall; Scientific and reasonable composition and proportioning had both been improved the use properties of coating; Can increase its additional properties again; Both because the existence of photocatalyst of titanium dioxide particle, effect such as coating possessed extremely strong sterilization, deodorizing, purify air.The photocatalyst technology is applied in the coating more can its environmental protection of fine performance, improves the function of environment, because coating is very extensive in the application of building field.
