Abstract

The invention discloses a sun-proof and heat-insulating coating for buildings and a preparation method thereof. The blend is obtained by mixing water-based acrylic resin, modified silica airgel, zinc phosphate, organic fluorine epoxy resin and silicone resin , put the blend into the mixing tank, stir evenly and then filter, and mix the boric acid microparticles and inorganic fillers into the SiO 2 In the sol precursor, it fills the defects in the nonlinear optical crystal, and then regulates the infrared radiation performance, and undertakes the function of enhancing the infrared radiation performance of the atmospheric window band. Adding a dispersant makes the molecular chain of the dispersant fully stretch in the aqueous solution. In SiO 2 A surface adsorption layer of a certain thickness is formed on the surface of the airgel particles, which produces a steric hindrance effect, thereby achieving the promotion of the development of high-grade green buildings and the improvement of SiO 2 The purpose of dispersion stability of airgel system.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to an architectural sun-proof and heat-insulating coating and a preparation method thereof. Background technique [0002] At present, there are various measures for building heat insulation, which are mainly realized through roofs, walls, glass, etc. Among the many measures, roofs and walls occupy the vast majority. Now most of them are painted with reflective insulation on their surfaces. Thermal coatings to reduce the impact of sunlight on the temperature of buildings, and at the same time achieve the purpose of reducing the surface temperature of buildings, thereby reducing the indoor temperature and making the room reach a relatively comfortable temperature. This is also one of the effective measures for high efficiency and environmental protection at present; [0003] In the construction field, reflective heat insulation coatings are commonly used for sun protection and he...
