Reflection type thermal insulation coating and various base material sticking power good, have good close capacitive with priming paint intermediate coat, weathering resistance is strong, and the general solvent used has no irritating odor, and greatly reduces the pollution of Construction on Environment, and effect of heat insulation comparatively isolation-type thermal insulating coating is obvious.
Radiation heat insulation type thermal insulating coating be by the form of radiation, coated article is absorbed sunshine light and heat with certain wavelength emission in air, thus reach good heat-insulating cooling effect, its gordian technique is the coating composition that preparation has high thermal emissivity.But preparation technology's more complicated of radiation paint, still can not obtain stable emittance.Radiation heat insulation coating is different from isolation-type and reflection type thermal insulation coating, because after both can only slow down but can not the transmission of block heat, after heat is slowly through thermofin and reflecting layer, the temperature of internal space raises lentamente, now, even if coating outside temperature reduces, heat energy also can only be stranded and fall into wherein, and Radiation Heat-insulated Paint can fall with the heat radiation of the form of heat emission by absorption, thus impel and lowered the temperature with same speed by inside and outside automatic doubler surface glouer.
In sum, three kinds of thermal insulating coatings have respective relative merits, more preferably be incubated for obtaining, heat insulation and preservative effect, need further to study the component of thermal insulating coating and content, obtain integrating the lagging material of obstructs, transmitting and radiation function to development.
