Abstract

The invention discloses a water-based pollution-resistant reflective thermal insulation coating and a preparation method thereof. The coating is prepared from an emulsion, nano-particles, polybenzimidazole, sodium tetraborate, hydroxyethyl cellulose, inorganic nonmetallic compounds, a reflecting material, a filling, a dispersing agent, a flexibilizer, a binder, glycol and deionized water. The preparation method comprises the steps of firstly mixing deionized water with the dispersing agent, heating in a warm water bath, sequentially adding the nano-particles, the inorganic nonmetallic compounds and a reflecting pigment, uniformly stirring, sequentially adding the emulsion, the hydroxyethyl cellulose, polybenzimidazole and sodium tetraborate, stirring, continuing to add the filling and glycol, finally adding the flexibilizer and the binder, and uniformly stirring. The coating disclosed by the invention has the properties of pollution resistance, high temperature resistance, reflectivity and the like as well as excellent adhesive force and scrubbing resistance, is high in tensile strength and elongation at break, good in decoration effect and low in construction cost and maintenance cost, and scars are unlikely to be formed; and the coating prepared from the environment-friendly raw materials is environmentally friendly and healthy.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based stain-resistant reflective 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. In order to solve the above problems, functional coatings with reflective heat insulation, covering fine cracks, and pollution resistance have emerged one after ...
