Problems solved by technology

[0003] However, there are few commercialized building thermal insulation coatings at present, and there are defects such as poor water resistance and pollution resistance, which make the thermal insulation effect of reflective thermal insulation coatings decay significantly, and the weather resistance is poor. Reflective thermal insulation coatings with high water resistance and pollution resistance relatively rare

Abstract

The invention relates to a novel heat-reflection heat insulation coating with high pollution resistance and water resistance. The coating adopts such raw materials as water-based acrylic emulsion, titanium dioxide, colloidal silica, mica powder, high-brightness aluminum silicate, fluorine or silicone polymer stuffing, propylene glycol, a dispersing agent, a wetting agent, a rheological additive, an adhesive attraction accelerating agent, and a film coating additive. Through an optimal design for matching ratio of the raw materials, the prepared heat insulation coating has the characteristics of high water resistance, high pollution resistance, high reflectance, good uniformity and sedimentation resistance, obvious reflection and insulating effects and excellent comprehensive performance.

Description

technical field [0001] The invention relates to a coating, in particular to a heat-reflecting heat-insulating coating with high pollution resistance and water resistance. Background technique [0002] Saving energy, reducing consumption, and improving economic benefits are one of the basic goals of scientific research and technology development, and coating technology is no exception. Architectural reflective coatings have a high reflectivity, which can effectively reflect solar radiation energy back to the atmospheric space, reduce the absorption of solar radiation energy by the building wall, and achieve the effect of reducing the wall and indoor temperature, thereby reducing the energy consumption of air conditioning and cooling in summer . [0003] However, there are few commercialized building thermal insulation coatings at present, and there are defects such as poor water resistance and pollution resistance, which make the thermal insulation effect of reflective therm...
