Described emulsion is one or more in pure acrylic acid emulsion, benzene emulsion, the organosilicon crylic acid latex;
Described auxiliary agent comprises dispersion agent, film coalescence aid, thickening material and defoamer; Wherein dispersion agent is with OROTAN 1288, the OROTAN 731A dispersion agent of U.S. Rhom and Hass, or a kind of in 5040,5027 dispersion agents of Henkel KGaA company; Film coalescence aid is the ether alcohol kind solvent; The thickening material ACRYSOL TT-935 or the TT-615 thickening material of Rhom and Hass; Defoamer is with the NXZ defoamer of the BYK024 of Bi Ke company or Japanese Nuo Puke company.
This has the preparation method of radiation heat insulation and isolation-type heat insulating coatings concurrently, with Fe
2O
3, MnO
2, Co
2O
3, CuO is raw material, by the proportioning weighing, grinds, and it is mixed, after sieving by 300 order mesh screens, put into ceramic crucible and place high-temperature electric resistance furnace to carry out solid state sintering, 800 ℃ of temperature, insulation 6h makes infrared radiant material, adds cenosphere by proportioning again and is mixed with the heat insulation function material; Press proportion speed weighing deionized water, dispersion agent, propylene glycol in container, stir, add pigment, filler, and shear, it is uniformly dispersed with high-speed shearing machine; Add the heat insulation function material, fully moistening after, make its dispersion by high speed shear again; Add emulsion, film coalescence aid, calcium carbonate crystal whisker, thickening material, defoamer, stirring at low speed makes its dispersion; Add proper ammonia, the pH that regulates latex coating is 8~9, promptly makes and has radiation heat insulation and isolation-type heat insulating coatings concurrently.
Beneficial effect of the present invention: of the present inventionly have the coating performance excellence that radiation heat insulation and isolation-type heat insulating coatings form concurrently on external wall, effect of heat insulation is obvious than single heat insulation mechanism thermal insulation coatings, its heat insulation effect can make the temperature difference reach 5~8 ℃, and has outstanding weathering resistance, guarantor's look gloss retention, water tolerance and washable wiping.Of the present inventionly have radiation heat insulation concurrently and the isolation-type heat insulating coatings does not contain benzene, formaldehyde, help environmental protection, and easy construction, tangible environmental benefit, social benefit and economic benefit had.
