Abstract

The invention discloses a doped nano pigment YAl 1‑ x m x o 3 The preparation method of (M=Fe, Co, Cu) comprises the following steps: 1) at normal temperature, get deionized water and stir on a magnetic stirrer, according to the molar ratio of Y, Al, and Fe, appropriate ferric nitrate, nitric acid Aluminum and yttrium nitrate are completely dissolved in deionized water successively, and after the above raw materials are completely dissolved, succinic acid is added as a stabilizer to obtain solution A; pH value, to obtain solution B, and then add 1,2-propylene glycol to solution B to obtain a mixed solution; 3) Stir the mixed solution obtained in step 2) on a 60°C constant temperature magnetic stirrer for 2h until the solution becomes condensed glue, then dried, ground, and calcined to obtain solid powder. The preparation method of the invention is green and pollution-free, and the obtained product has the advantages of good dispersibility, low energy consumption, uniform particles, environmental friendliness, low synthesis temperature, simple and controllable process, and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of nano pigments, in particular to a preparation method of nano pigments YAl1-xFexO3 with high near-infrared reflection and good durability. Background technique [0002] Nanoscale inorganic white pigments inherently have a high refractive index (n=2.2 to 2.7) and contribute to light scattering at all wavelengths. They are characterized by high solar absorption in the near infrared region (780 to 2500nm) and ultraviolet (UV) region (290 to 400nm), making them ideal for multifunctional, optically clear surface coatings. Since infrared radiation in the wavelength range of 810 to 1100 nanometers is said to be the main cause of heat, NIR reflective white pigments have become necessary for the design of heat-controlling surface coatings and functional coatings. Furthermore, it has been recognized that the gradual increase in atmospheric temperature is a net effect of CO2 emissions from different sources, includi...
