Abstract

The invention belongs to the field of coatings and particularly relates to a thermal insulation coating for an exterior wall of a building. The thermal insulation coating is prepared from 45-60 parts of a base emulsion, 8-12 parts of glass beads, 7-10 parts of titanium dioxide, 7-12 parts of filler, 8-13 parts of water, 8-13 parts of a coalescing agent, 0.1-0.3 parts of a leveling agent, 0.5-1.5 parts of a thickening agent, 0.4-1 part of a wetting agent, 0.4-0.8 parts of a dispersant, 0.1-0.3 parts of a defoaming agent and 0.3-0.5 parts of a pH regulator, wherein the base emulsion is a copolymer emulsion of fluoralkene and vinyl ester. The specific base emulsion is adopted, the proportion of components of the coating is designed in an optimized manner, and the obtained coating has thermal insulation and reflection functions, has high reflectivity, good uniformity, excellent anti-sedimentation performance and good adhesion, has stable and excellent performance and is high in weather fastness and water resistance.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a heat-insulating coating for building exterior walls. Background technique [0002] Exterior wall coatings can protect the exterior walls of buildings that have been exposed to wind, sun, and rain for years. They must have good enough water resistance, weather resistance, stain resistance and freeze-thaw resistance to ensure good performance. decorative effect and durability. Not only that, under the high radiation of the sun, the surface of the building is raised, and the heat is transferred to the interior of the building, which increases the working pressure of cooling equipment such as air conditioners, resulting in excessive energy consumption, which also requires Coatings can have the effect of heat insulation. In recent years, some reflective heat insulation materials and manufacturing methods have also appeared in the paint market, such as a Chinese invention patent with the pat...
