A kind of composition of energy reflecting sun heat radiation comprises following component: filmogen 20-70%, solvent 20-60%, hollow minute particle 2-10%, infrared powder 2-10%, nano titanium oxide 0.1-1%, auxiliary agent 4-20% by weight percentage.
Described filmogen is resin or emulsion, and described resin can be one or more in acrylic resin, Resins, epoxy, Synolac, vibrin and other coating resin; Described emulsion can be one or more in the emulsion of synthetic resin emulsion, polymer emulsion and other coating.
Described solvent is water or organic solvent, and described organic solvent can be one or more in hydro carbons, alcohols, ethers, ketone and the esters solvent.
Described auxiliary agent can be one or more in dispersion agent, defoamer, pH value conditioning agent, film coalescence aid, thickening material, flow agent, reflection mill base, sanitas, wetting agent, biocide, antithrombotics, tinting material, solubility promoter, UV stablizer, adhesion promoter and other coating used additives.
Hollow minute particle can heat insulation and heat control, and infrared powder can reflect solar heat, and nano titanium oxide is sun-proof, antiultraviolet has the anti-fouling and self-cleaning function simultaneously,
Solar heat radiation reflection coating disclosed in this invention can be widely used in grain storage field, petrochemical industry, power industry, industrial production field and general industry covil construction field etc., the housing that can be used for electric equipment products such as electronic product, street lamp etc. can also be used for the car surface spraying.
It is main impetus that the composition of energy reflecting sun heat radiation disclosed in this invention is concentrated section the most with 400-1750nm heat energy.Solar heat radiation reflection coating disclosed in this invention possesses following advantage: (1) solar heat radiation reflection coating can form efficient reflective insulation layer in coating, can reduce the quantities received of heat energy greatly, increase the temperature difference of film coated surface and internal layer, 0.3mm existing 95% insulation effect reduces building energy consumption and can reach 50%; (2) when ambient air temperature is lower than the film coated surface temperature, being received heat energy outwards launches from film coated surface with forms of radiation (hemispherical emissivity) again, further reduce the accumulation of coatingsurface heat energy again, the heat energy of only remaining not enough sun heat radiation total amount 5% is accumulated in to film and upward and to internal layer conducts at last, makes the temperature difference of coating outside surface and internal layer appearance more than 10 ℃.Heat-protection building material disclosed in this invention has the advantage that self possesses the solar heat radiation reflection ability.That is to say, the solar heat radiation reflection coating or the heat-protection building material that no matter comprise the composition of energy reflecting sun heat radiation disclosed in this invention, can both guarantee to reach at least under the prerequisite of low-cost, less energy-consumption 〉=85% solar heat radiation reflection rate, 〉=85 hemispherical emissivity and 〉=10 ℃ the heat insulation temperature difference.
