Problems solved by technology

But there is following unavoidable problem in this thermal insulation coating industry: (1) the addition of hollow microspheres can reduce the reflectivity of coating to visible light; For occasions where strict requirements are required, the use of hollow microbeads is limited, and it is a thin-walled porous structure, which is easily broken under high shear and reduces the heat insulation effect; (3) Hollow microbeads are used as the main solar heat reflection functional material. In addition to heat reflection and infrared reflectivity, the heat insulation effect of coatings is also directly related to thermal conductivity. Generally, thick coating is required, and it is difficult to obtain a flat paint film. The anti-fouling ability is poor, resulting in It leads to a decrease in emissivity and reflectivity, which in turn affects the thermal insulation performance; (4) Due to the light weight of the hollow microspheres, it is easy to condense upward during the storage of the paint and the problem of poor leveling of the construction part

Abstract

The invention relates to an exterior wall coating with a solar heat reflecting function and a preparation method of the exterior wall coating. The exterior wall coating with the solar heat reflecting function is prepared from the following components: water, an emulsion, a self-made solar heat reflecting powder, titanium dioxide, calcined kaolin, calcium carbonate, talcum powder, a wetting agent, a dispersing agent, a defoaming agent, an antibacterial preservative, a coalescing agent, an antifreezing agent and a thickening agent. The exterior wall coating with the solar heat reflecting function is relatively high in total solar energy reflectivity, capable of playing a favorable heat insulation effect after being thinly coated and also capable of avoiding the condition that a film is crude and nonresistant to dirt.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an exterior wall coating with solar heat reflection function and a preparation method thereof. Background technique [0002] At present, my country's building energy consumption accounts for about 1 / 3 of the total energy consumption, and the energy consumption per unit area of ​​buildings is 2 to 3 times that of developed countries with similar international climate conditions. Therefore, the development of new materials with low energy consumption and good thermal insulation performance has become the mainstream trend. The Ministry of Construction has fully implemented the energy-saving building certification system since 2007. The huge building energy-saving market will drive the new development of the architectural coatings industry, so my country is the largest market for energy-saving coatings with the most development potential. [0003] According to the heat insulation functional ...
