Abstract

The invention provides a coating modifying additive and a thermal insulation coating and a preparation method thereof. A finishing paint modifying additive including titanium dioxide, mica and glass flakes and a priming paint modifying additive including titanium dioxide, nanometer indium tin oxide, nanometer tin antimony oxide, nanometer tourmaline powder, nanometer silicon dioxide and nanometersilicon carbide are added into finishing paint and priming paint. According to the finishing paint of the coating, firstly, reflection is generated for solar light irradiation, then, remaining solar energy is irradiated out through absorption of the priming paint coating, energy between ranges is irradiated out in the mode of infrared light through the nanometer tourmaline powder, the nanometer titanium dioxide, the nanometer indium tin oxide and the nanometer tin antimony oxide in the priming paint modifying additive, and then the temperature of a coating matrix is lowered. Raw materials arecheap and easy to obtain, the preparation method is simple, the thermal insulation effect is good, the effects of resisting bacteria and purifying air are achieved, and the thermal insulation coatingis multifunctional and environmentally friendly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a coating modification additive, a heat-insulating coating and a preparation method thereof. Background technique [0002] With global warming, the ozone layer is destroyed, making the sun's rays shine on the building more intensely. When the sun's rays shine on the outer surface of the building, the energy of the sun's light is absorbed by the building and transmitted to the inside of the building. As the temperature rises, the internal space becomes uncomfortable. At the same time, increasing the burden on the air-conditioning system increases energy consumption and carbon dioxide and greenhouse gas emissions, which not only poses hidden dangers to the safety of equipment and facilities, but also pollutes the environment. Especially in low-latitude areas, the sunshine time is long and the radiation is large, and it is necessary to avoid indoor heating caused by sunlight. Yongxing Islan...
