Water-borne architectural color coating with light reflection function and preparation method of coating

Abstract

The invention relates to a water-borne architectural color coating with a light reflection function. The water-borne architectural color coating is characterized by comprising the following components: elastic acrylic latex, rutile titanium dioxide, crystal form infrared reflection titanium dioxide, white carbon black, a hollow microsphere emulsion, mica powder, kaolin, talc, calcium carbonate, a dispersing agent, a wetting agent, an antifoaming agent, an anticorrosive agent, a mould inhibitor, a pH regulator, a coalescing agent, an antifreezing agent, a thickener, a leveling agent, an organic pigment and an inorganic pigment, wherein the hollow microsphere emulsion adopts a modified acrylate organic polymer as the sphere wall and is hollow inside. The water-borne architectural color coating with the light reflection function is used for coating an external wall of a building, can effectively reduce the surface temperature of the building so as to save air conditioning energy consumption, and can be used in areas with hot summer; a product can meet the requirement of customers for different colors, the energy-saving effect is obvious, energy saving and attractiveness are realized, and the water-borne architectural color coating has outstanding essence characteristics and significant progress compared with the coating only adopting white color or other light colors in the prior art.

Description

technical field [0001] The present invention relates to a kind of light-reflecting and heat-insulating coating for exterior walls of colored buildings, in particular to a water-based color coating for energy-saving decoration and protection of exterior walls of buildings with high solar reflectance and near-infrared reflectance; especially suitable for summer heat In warm-winter and hot-summer-cold-winter regions, the effect of reflective heat insulation is outstanding, which can effectively reduce the surface temperature and indoor temperature of buildings, thereby significantly saving air-conditioning energy consumption. Background technique [0002] my country has a large population, consumes a lot of energy, and is still a country that lacks energy. Energy conservation, energy conservation and emission reduction, ecological environmental protection, and low-carbon circular economy are the basic models of my country's economic development. Building energy saving is one of...

Problems solved by technology

White paint has the best light reflection performance, but in practical applications, white or light-colored paint films have the disadvantage of poor stain resistance, and it is difficult to meet the decorative needs of modern building exterior walls for different colors. Therefore, the development of high reflectance ratio The color architectural light reflection and heat insulation coating can effectively make up for the above shortcomings, and is environmentally friendly, energy-saving, and has high practical value.
