Abstract
The invention discloses a thermal insulating coating for a building exterior wall and a preparation method of the coating. The thermal insulating coating is prepared from the following raw materials in mass percent: 75%-80% of styrene acrylic emulsion, 5%-8% of zinc oxide powder, 3%-8% of mica sheet powder, 0.2%-0.5% of cation surfactant, 1%-2% of fumed silica, 0.1%-0.2% of pigment and 5%-10% of sodium carbonate powder, wherein the cation surfactant is a quaternary ammonium salt type cation surfactant. The thermal insulating coating for the exterior wall has an excellent ultraviolet resisting function and an excellent light reflecting function and is capable of realizing thermal insulation effectively since the zinc oxide powder and the mica sheet powder are added into the styrene acrylic emulsion. After being tested, the coating for the building exterior wall prepared by the method disclosed by the invention is capable of reducing a temperature by 9-10 DEG C higher than that of the market exterior wall coating under sunlight of 35-37 DEG C in a sealed state in 2 hours, and the coating has an obvious cooling effect.
