Problems solved by technology

[0003] The problem of reflective heat-insulating coatings is mainly in two aspects: the lack of stain resistance of the coating film is the primary problem restricting the promotion of reflective heat-insulating coatings. Very serious pollution, followed by poor aging resistance of the coating film, serious fading, discoloration, loss of light, chalking and cracking of the coating

Abstract

The invention relates to the technical field of coatings and particularly relates to a reflective thermal insulation coating having a self-cleaning function. The reflective thermal insulation coating comprises 15%-25% of water, 30%-60% of an acrylic synthetic emulsion, 0.1%-2% of a thickener, 0.5%-3% of a defoamer, 0.6%-3% of a dispersant, 0.05%-0.5% of a wetting agent, 5%-20% of hollow glass beads, 5%-20% of hollow ceramic powder and 0 .5%-5%of a self-cleaning aid. The reflective thermal insulation coating is modified by a nano-material so that coating performances are greatly improved and other performances such as scouring, acid and base resistance are improved. The self-cleaning aid mainly comprises nanometer titanium dioxide. Under sunlight irradiation, nanometer titanium dioxide undergoes a photocatalytic reaction so that pollutants on the wall surface are decomposed. Photoinduction produces super-hydrophilic effects so that pollutants on the outer wall surface can be removed easily by rain and cleaning effects are obtained.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a reflective heat-insulating coating with self-cleaning function. Background technique [0002] At present, my country's building energy consumption accounts for about 1 / 3 of the total energy consumption, and the heating energy consumption per unit area of ​​the building is 2-3 times that of developed countries with similar international climate conditions. The proportion of the entire heat transfer is small, and the thermal effect caused by solar radiation is the main cause of indoor heat in summer. Reflective heat insulation coatings can reflect the radiant heat of the sun, thereby reducing the heat in the room, effectively reducing the energy consumption of artificial refrigeration, and having a great effect on building energy saving. [0003] The problem of reflective heat-insulating coatings is mainly in two aspects: the lack of stain resistance of the coating film is the p...
