[0085] ①. Solution A is zirconium oxychloride ZrOCl 2 .8H 2 Preparation of O absolute ethanol solution

[0086] First preparation concentration is 2000 milliliters of dehydrated ethanol solutions of zirconium oxychloride of 0.5mol / L, then in prepared solution, adding molecular weight is 12 grams of polyethylene glycols of 2000, stirs;

[0087] ②. Solution B is the preparation of absolute ethanol solution of butyl titanate

[0088] First prepare 2325 milliliters of absolute ethanol solution of butyl titanate with a concentration of 0.3 mol / L, then add 13 grams of triethanolamine to the prepared solution, and stir evenly;

[0089] ③. Prepare the aqueous ammonium bicarbonate solution whose molar concentration is 2.0mol / L;

[0090] ④. Preparation of mixed sol

[0091] First, ...

Embodiment 2

[0098] According to the method and steps of Example 1, the specific formula and process conditions are as follows: prepare 2000ml of 1.5mol / L zirconium oxychloride dehydrated alcohol solution, and add 21g polyethylene glycol, stir well; use dehydrated alcohol as solvent preparation 1265ml of 0.5mol / L butyl titanate solution, and add 11g of triethanolamine to the solution, and stir evenly; prepare an aqueous ammonium bicarbonate solution with a molar concentration of 1.0mol / L; Mix the two solutions, spray the ammonium bicarbonate aqueous solution to the mixed solution of a and b under stirring, the reaction temperature is 70°C, stop adding until the final pH value is 7-8, continue to stir for 7 hours, and age 15h, filter, wash; the dehydration and drying process uses isobutanol as an entrainer, and the azeotropic point is 89.9°C. After dehydration is completed, the temperature of the system rises to the boiling point of isobutanol, 108.4°C. At this temperature, isobutanol is eva...

Abstract

The invention relates to a special nano zirconium dioxide composite powder material for architectural outer wall insulation paint and a preparation method thereof, 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 architectural outer wall 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 architectural outer wall reflective insulation paint. The material is suitable for an architectural outer wall insulation coating. The prepared paint conforms to performance indexes specified in CB / T25261-2010.

Description

technical field [0001] The invention relates to a nano zirconia composite powder material specially used for reflective and heat-insulating coatings on building exterior walls. 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 sun moves at 1.765×10 per second 17 J's energy shines on the earth, bringing light to life on the earth, and also providing human beings with inexhaustible energy. But the strong radiation of the sun can also cause the indoor temperature of the building to be too high, and people have to rely on air conditioners to obtain a suitable living environment....
