Abstract

The invention relates to a reflective heat-insulation primer-topcoat integrated exterior wall coating and a preparation method thereof. The coating is prepared from the following raw materials: water, a pH regulator, hydroxyethyl cellulose, a primer emulsion, a topcoat emulsion, a preservative, a wetting dispersant, a defoaming agent, titanium dioxide, mica powder, reflective heat-insulation titanium dioxide, an antifreeze agent and a thickening agent. According to the invention, various emulsions and assistants are screened and dosages and proportions are researched, so that the reflective heat-insulation primer-topcoat integrated exterior wall coating is developed, and the reflective heat-insulation primer-topcoat integrated exterior wall coating has the sealing property of a primer, the aging resistance of a topcoat and the reflective heat-insulation effect at the same time.
