Composite heat-insulating paint for exterior walls and preparation method of composite heat-insulating paint

Abstract

The invention discloses composite heat-insulating paint for exterior walls and a preparation method of the composite heat-insulating paint. The composite heat-insulating paint is prepared from purified water, an inorganic dispersing agent, a defoaming agent, texanol ester alcohol, rutile titanium dioxide, nano-titanium silicate microporous powder, porous expansible microspheres, infrared reflection nano-pigment, a self-crosslinking fluorocarbon emulsion, a photocured elastic emulsion, a macromolecular porous polymer, a nano-zirconium dioxide dispersing agent, a nano-titania colloid, a nano-silica solution, a nano-silver antibacterial agent and a PU thickening agent. The heat-insulating paint has efficient heat radiation reflection performance, good heat insulation and self-cleanness, lasting heat, good decorative performance, wide applicability and great environment friendliness, and a coating is long in service life.

Description

technical field [0001] The invention relates to the field of paints, in particular to a composite heat-insulating paint for exterior walls and a preparation method thereof. Background technique [0002] Heat-insulating paint is a new type of energy-saving material, which not only meets the requirements of national energy-saving standards, but also meets the requirements of environmental protection and safety. The cost performance is reasonable, and the proportion of usage in the market is increasing year by year. Traditional heat insulation paints generally use ceramic hollow microspheres as heat insulation fillers, and ordinary acrylic emulsions as adhesives. They are basically white or light-colored. The heat insulation effect of other colors will not be obvious, and the durability and stain resistance will be poor. .

Problems solved by technology

Traditional heat insulation paints generally use ceramic hollow microspheres as heat insulation fillers, and ordinary acrylic emulsions as adhesives. They are basically white or light-colored. The heat insulation effect of other colors will not be obvious, and the durability and stain resistance will be poor.

The heat insulation method of traditional heat insulation paint is to delay the flow of heat by adding hollow microspheres in the paint to achieve the purpose of heat insulation, but they can only delay the flow of heat, but they cannot stop the flow of heat, so as long as there is a temperature difference between the two aspects The heat will continue to go to the side with lower temperature, which is why the heat insulation effect will not be obvious when the external temperature is high for a long time)
