Abstract

The invention discloses a building sunscreen heat insulation coating and a preparation method thereof. The preparation method comprises the following steps: mixing waterborne acrylic resin, modified silicon dioxide sol, zinc phosphate, organic fluorine epoxy resin and organic silicon resin to obtain a blended material, adding the blended material into a stirring tank, uniformly stirring, and filtering. Boric acid microparticles and an inorganic filler are doped into a SiO2 sol precursor, so defects in the nonlinear optical crystal are filled, the infrared radiation performance is further regulated and controlled, and the function of enhancing the infrared radiation performance of the atmospheric window wave band is achieved; and a dispersing agent is added the molecular chain of the dispersing agent can be completely expanded in an aqueous solution, and forms a surface adsorption layer with a certain thickness on the surfaces of SiO2 aerogel particles, and a steric hindrance effect is generated, so that the aims of promoting the development of high-grade green buildings and improving the dispersion stability of a SiO2 aerogel system are fulfilled.

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...
