Two, first component is prepared:
Connect step, by reference to the accompanying drawings 1, acrylic acid modified polyhydroxy resin, auxiliary agent are weighed by proportion speed and adds charging basket, and add partial solvent, with high speed dispersor stirring at low speed 5 ~ 45min, filler and the pigment of step acquisition is added after being uniformly dispersed, high-speed stirring 15 ~ 60min, grinds 0.5 ~ 4h again and reaches less than 60 μm to coating fineness after being uniformly dispersed, by residual solvent adjustment viscosity to suitable scope, detect viscosity, qualified rear filtration, discharging, tinning and packaging;
Three, coating preparation:
First component and second component are mixed by proportioning, stirs, can application be carried out.
For the resin of the low solar energy absorbing paint of dark color in the present invention, should have lower to visible ray, infrared Absorption rate and weathering resistance preferably, therefore should select that transparency is high, not easily be sunlighted and the resin of cracking comparatively greatly containing heat absorption group, molecular bond energies such as C O C, C=O, O H less in molecular structure as far as possible.Based on the high IR optical transparency of urethane resin, containing a large amount of bond energy higher C=N key, good weatherability, select acrylic acid modified polyhydroxy resin and aliphatic polymeric isocyanate as the resin binder of the low solar energy absorbing paint of dark color;
Selecting main coloring pigment, reaches earth surface solar radiation energy distribution and is roughly: UV-light 5%, visible ray 45%, infrared light 50%.The reflection of visible light part determines primarily of the color of coating, and color is darker, and visible light reflectance is lower, and dark paint has the visible reflectance lower than whitewash.For specific color, as Dark grey, visible light reflectance is determined, so total solar energy reflection is than determining primarily of its infrared reflectance.The key of modulating dark heat reflection coatings is the dark pigment selecting high infrared reflection.Desirable dark heat reflection pigment should have at visible light wave range and absorbs more by force, and has high-reflectivity at near-infrared band.Select the high near infrared reflectivity dark material be made up of Copper-cladding Aluminum Bar semiconductor oxide zinc and Copper-cladding Aluminum Bar sodium-zinc-phosphate as black pigment, the one of sodium-zinc-phosphate, titanium dioxide or be combined as high near-infrared reflection white pigment, cobalt, zinc, phosphorus mixed oxide are high near-infrared reflection blue pigments, copper, zinc, composite phosphorus oxide are high near-infrared reflection veridian, and iron, zinc, composite phosphorus oxide are high near-infrared reflection red pigment.
Because dark coating has high specific absorption at visible light wave range, also certain absorption is had at near-infrared band, by improving the emittance of dark coating, thus by arrive the solar radiation Conversion of energy on its surface be heat reflection electromagenetic wave radiation in air, and then improve its temperature reduction performance.Select the one of the silicon carbide of high emissivity, zirconium dioxide, Wingdale, gypsum or combine as functional stuffing, coating being fallen with the heat radiation of the form of heat emission by absorption, thus impels coated article body indoor and outdoor to keep same rate of temperature fall.
The present invention has high near infrared reflectivity and high mid and far infrared reflectivity and low thermal conductivity, is applied to ship deck and superstructure, significantly can reduces the absorption of hull surface to solar radiation energy, reduces temperature in cabin, and then saves air-conditioning expense.The present invention also can promote the use of the fields such as factory building, pressure vessels for the chemical industry, steel construction, terrace, external wall, plays cooling-down effect, and economical effectiveness is obvious, wide market.Ultraviolet-visible light-the near-infrared spectral reflectance of the low solar energy absorbing coating of a kind of dark color is shown in accompanying drawing 2.
The present invention is two component chemical reaction curable coatings, and coating can adopt two component airless spraying, high pressure Air spraying, roller coat, application is carried out in brushing, recommends application thickness to be 100 μm.Embodiment and products thereof detected result sees the following form.
