Special nano zirconium dioxide composite powder material for glass reflective insulation paint

Abstract

The invention relates to a special nano zirconium dioxide composite powder material for glass reflective insulation paint, belonging to the field of manufacturing of metal oxide ultrastructures. The material is characterized by comprising the following chemical components in percentage by mass: 70-90% of zirconium dioxide (ZrO2) and 10-30% of titanium dioxide (TiO2). The preparation method comprises the following steps: continuously spraying an atomized ammonium bicarbonate water solution into an anhydrous ethanol solution (which is prepared by respectively preparing zirconium oxychloride (ZrOCl2.8H2O) and tetrabutyl titanate and mixing evenly) in a stirring state to react to obtain a mixed sol, carrying out azeotropic dehydration on the mixed sol by using butanol as an azeotrope former to obtain a dry material, and calcining to obtain the special nano zirconium dioxide composite powder material for glass reflective insulation paint, of which the particle size is 30-50nm and the specific area is greater than or equal to 30 m<2> / g. The invention provides a high-activity high-dispersity high-stability special nano zirconium dioxide composite powder material for glass reflective insulation paint, and a preparation method and application method thereof. The sunlight reflectance of the prepared paint for white is up to 0.85; and the hemispherical emittance is up to 0.85.

Description

technical field

[0001] The invention is a nano-zirconia composite powder material specially used for glass reflective and heat-insulating coatings. It belongs to the manufacture of metal oxide ultramicrostructure. Background technique

[0002] Saving energy and protecting the environment is a crucial issue for the sustainable development of the world economy and even human life. According to statistics, building energy consumption accounts for 30% to 40% of the total human energy consumption. The energy is mainly used for heating and cooling electricity consumption in the building.

[0003] The door and window glass of a building can provide indoor ventilation, light transmission, outdoor perception, noise blocking and other functions, so it is an important component that must be installed in buildings, vehicles, and engine rooms.

[0004] Nanoparticles are aggregates composed of a small number of molecules or atoms. They are between macroscopic substances and microscopic...
