Problems solved by technology

However, as a heat-reflecting functional material, titanium dioxide only plays a role on the surface layer of titanium dioxide particles, and titanium dioxide is a high-energy-consuming material. Its application in exterior wall coatings has poor heat insulation and reflection functions, single color paint, and low cost. high

Abstract

The invention relates to a coating with heat insulation and reflection effects and preparation method thereof. The coating with heat insulation and reflection effects disclosed by the invention comprises the following components: water, emulsion, a home-made functional material with heat insulation and reflection effects, titanium dioxide powder, calcined kaolin or water-wasehd soil, calcium triple superphosphate, a wetting agent, a dispersing agent, an antifoaming agent, a germicide anticorrosive agent, a coalescent and an antifreezing agent. The coating with heat insulation and reflection effects has the advantages of relatively high total solar energy reflectivity (greater than 85%) and good construction performance, the paint film is smooth and flat, the situation that decrease of reflectivity and emissivity in use affects the heat insulation effect is avoided and the weather resistance of the paint film can be improved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a coating with a heat-insulating and reflecting function and a preparation method thereof. Background technique [0002] The intensity of solar radiation received by the earth's surface is 1368W / ㎡, which is the main source of the earth's heat and the reason for the high temperature in summer. Therefore, air-conditioning energy consumption has become the main aspect of building energy consumption. With the in-depth development of building energy conservation in our country, the research on heat-insulating reflective coatings is increasingly valued by the government and enterprises. Heat-insulating reflective coating is a coating that mainly reflects the near-infrared part of sunlight effectively. It can reduce the absorption of solar radiation energy by the surface of an object, and is a passive cooling coating. [0003] Among the solar heat that everyone knows at present, ultraviolet li...
