Description
Technical field
The present invention relates to a kind of coating with heat insulation self-cleaning function.
Background technology
Along with science and technology development, various modern buildings be presented in people in face of, like glass body of wall, metallic object packing etc.Have at present many novel buildings to adopt the building of Roof system, the especially steelwork of metal construction again, its Roof system also adopts the Roof system of metal construction naturally.The composite metal Roof system is used more and more widely in buildingss such as all types of industries, physical culture, amusement, exhibition center, retail supermarket.Metal Roof system need be used metal roofing board and metal construction base plate.In addition, in various building systems, also generally use the metal wall panel at present.The coated metallic plate that is used for metope or roofing enclosure comprises above-mentioned metal roofing board, metal construction base plate and metal wall panel, can be referred to as metal enclosing guard plate.
The metal current wall interior panel has wide range of applications, and it has advantages such as durable, attractive in appearance.But along with the growth of duration of service, its outside surface can be stained with objectionable impuritiess such as impurity such as dust granules and breed bacteria and but be difficult for discovering; And, clean utmost point trouble because the general suspension of metal enclosing guard plate is higher, therefore existing metal enclosing guard plate seldom carries out cleaned at regular intervals; Along with the growth of duration of service, get confused easily, shade in the surface of metal enclosing guard plate, influences the aesthetics of product.
In addition, adopt metal enclosing guard plate to go along with sb. to guard him, in temperature higher summer, because the heat absorption of metal enclosing guard plate; Can cause its interior space temperature of going along with sb. to guard him very high, in temperature lower winter, because the thermal conductivity of metal; Then cause its interior space temperature of going along with sb. to guard him low excessively,, generally adopt the mode that adds thermofin and lagging material to carry out heat insulation at present in order to overcome Influence of Temperature; But this mode not only takes up room, and installation workload is big, and installation effectiveness is low.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art; A kind of coating with heat insulation self-cleaning function is provided; Adopt this coating can directly apply on the metal enclosing guard plate; Good heat-insulation effect, environmental protection, health, convenience for washing, attractive and durable can reduce the construction working amount of metal enclosing guard plate thermofin.
The technical scheme that the present invention adopted is: the present invention has the coating of heat insulation self-cleaning function and is made up of the material of following weight percent: pvdf 60～90%, and CNT 5～10%, titanium oxide 1～5%, pigment 5～10%, all the other are additive.
Said titanium oxide is Nano titanium dioxide.
Said additive comprises one or more in membrane-forming agent, dispersion agent, flow agent, skimmer, mould inhibitor, the sanitas.
Said pigment is one or more in red iron oxide, yellow oxide of iron, white titanium pigment, phthalocyanine blue, permanent yellow, the permanent bordeaux.
The invention has the beneficial effects as follows: because the present invention adopts pvdf, CNT, titanium oxide as main raw material; It is a kind of fluorocarbon coating; Dramatic benefit with fluorocarbon coating; Have good weathering resistance, thermotolerance, lower temperature resistance, chemical proofing, strong adhesion, and have unique not viscosity and low friction property, coating can form the supercoat of excellent property behind hot setting; Advantages such as its coating has weather-proof, anti-contamination, protects look, good toughness, wear-resisting, shock-resistant, chemicals-resistant corrosion are a kind of ideal facing materials; Pvdf (PVDF) is one of fluorocarbon coating main raw material, because PVDF has superpower weathering resistance, and life-time service out of doors, service free, so such coating is widely used in fields such as power house, airport, motorway, Highrise buildings; CNT is claimed carbon nanotube again, is to be built the breadboard physicist's Sumio Iijima of ripple NEC by Japan in January, 1991 to use the Analytical high resolution Electronic Speculum from the thomel that arc process is produced, to find that carbon nanotube has high-modulus, high-intensity mechanical property; The hardness and the diamond of carbon nanotube are suitable; But have good snappiness, can stretch, it is corrosion-resistant, high temperature resistant, thermal expansivity is little, opposing thermal change performance is strong; Carbon nanotube has good heat-blocking action in the present invention; But it is at coatingsurface lack of alignment or ordered arrangement, and when its ordered arrangement, effect of heat insulation is especially outstanding; Titanium oxide is as photocatalyst, and the light source irradiation through certain can promote most organic cpds generation oxidizing reactions, and the oxidation step of going forward side by side generates CO
2And H
2O, it acts on wide spectrum, in the photocatalyst reaction process, can not only destroy biotic factor; Also can destroy various organic chemicalss, promote the carrying out of chemical reaction, harmful organic gas is had certain oxygenolysis, therefore have purifying air, environment is antibiotic and the de-odorised function; Changed traditional environmental purification technology mode, titanium oxide tool strongly hydrophilic in addition is so the surface has self-cleaning function; Keep bright and clean forever, clean conveniently, prevent that dirt from adhering to, in addition in the photocatalyst reaction process; Titanium oxide is not participated in reaction and is not discharged objectionable impurities, only plays the catalysis instrumentality, and itself does not prolong in time and consumes; Self property is constant before and after the reaction, in reaction process, the material that is acted on is completely oxidized to innoxious substances such as harmless carbonic acid gas and water, and is therefore harmless fully to environment; Help HUMAN HEALTH, and work-ing life is lasting, is suitable for the lifelong of metal enclosing guard plate and effectively uses; It can play a role containing under the multiple light sources such as faint ultraviolet light, natural light, sunlight, so coating of the present invention has heat insulation and self-cleaning function, adopts this coating can directly apply on the metal enclosing guard plate; Good heat-insulation effect, environmental protection, health, convenience for washing, attractive and durable can reduce the construction working amount of metal enclosing guard plate thermofin.
