Abstract

The invention belongs to the technical field of inorganic metal oxide toner, and particularly relates to blue-phase black infrared reflection nano toner and a preparation method thereof. The preparation method comprises the following steps of: (1) material preparation: weighing 40-50% of calcium carbonate, 20-30% of manganese carbonate, 10-20% of strontium carbonate, 0-20% of copper oxide and 0-20% of titanium dioxide according to the mass fraction, and dispersing the weighed raw materials at a high speed for 2 h; (2) grinding and sieving: drying, crushing and sieving the materials dispersed in the step (1); (3) sintering: sintering the materials obtained in the step (2) in a track kiln, raising the temperature for 300 minutes to 800-1200 DEG C, keeping the temperature for 6 hours, and naturally cooling to room temperature; (4) coarse grinding: performing coarse grinding on the powder obtained by sintering to 20-25 microns, and drying the powder; and (5) secondary sintering: putting the powder obtained in the step (4) into the track kiln, carrying out secondary calcining at the calcining temperature of 1100 + / -100 DEG C, and accurately grinding the obtained powder until the particle size is less than 1 micron. The infrared reflectivity can reach 60-70%, the blackness is high, a blue phase is displayed, and the color mixing use is convenient.

Description

technical field [0001] The invention belongs to the technical field of inorganic metal oxide toner, and in particular relates to a blue phase black infrared reflection nano toner and a preparation method thereof. Background technique [0002] As the climate warms, reflective coatings can effectively reduce the surface temperature of objects. In the past two decades, they have developed rapidly and are widely used in construction, chemical, electric power, military camouflage and other industries to help people save energy and create a comfortable environment. [0003] The key technology of reflective coatings is the infrared reflective toner that can reflect the infrared rays in sunlight. This toner can reflect most of the energy brought by sunlight. At present, reflective paint mainly uses white toner or light-colored toner, because it has a good reflection effect on the visible light and near-infrared part of sunlight. However, because white is prone to yellowing and peopl...
