The invention relates to a reflective and heat-isolation
coating and a preparation method thereof. The reflective and heat-isolation
coating is characterized by being prepared from the following raw materials in parts by weight: 40 to 60 parts of macromolecular
emulsion, 4 to 8 parts of composite hollow microspheres, 10 to 20 parts of
rutile type
titanium dioxide, 1 to 3 parts of
flame-retardant agent, 0.5 to 2 parts of filming additive, 0.1 to 0.5 part of
wetting agent, 0.1 to 0.5 part of dispersant, 0.1 to 0.5 part of
preservative, 0.05 to 0.2 part of defoaming agent, 0.01 to 0.2 part of
thickening agent, and 10 to 20 parts of deionized water, wherein the macromolecular
emulsion is a
mixed solution of
acrylate emulsion and
polyurethane emulsion; the composite hollow microspheres comprise hollow glass microspheres, hollow
ceramic microspheres, and
fly ash hollow microspheres. The reflective and heat-isolation
coating has the advantages that the components are scientifically compounded, the usage amount of the coating is small, the use cost is low, the reflective and heat-isolation effects of the coating
thin layer are good, the construction is rapid, the anti-
cracking property, anti-
dirt property and weather-resistant property are good, and the certain
flame-retardant function is realized.
