Abstract

The invention discloses a preparation method of a YAl1-xMxO3 (M equals Fe, Co and Cu) nano-pigment. The preparation method comprises the following steps: firstly, at normal temperature, taking deionized water, stirring on a magnetic stirrer, sequentially and completely dissolving moderate ferric nitrate, aluminum nitrate and yttrium nitrate into the deionized water according to the molar ratio ofY to Al to Fe, and adding succinic acid as a stabilizer to obtain a solution A after the raw materials are completely dissolved; secondly, after a substance in the mixed solution A is completely dissolved, dropwise adding ammonium hydroxide and adjusting a pH value of the solution A to obtain a solution B, and then adding 1,2-propylene glycol into the solution B to obtain a mixed solution; and thirdly, stirring the mixed solution in the second step on a 60 DEG C thermostatic magnetic stirrer for 2 hours until the solution forms gel, and then drying, grinding and calcining to obtain solid powder. The preparation method disclosed by the invention is green and pollution-free; an obtained product has the advantages of high dispersity, low energy consumption, uniform particles, excellent environment friendliness, low synthetic temperature, simple and controllable process, suitability for large-scale production and the like.

Description

technical field [0001] The invention belongs to the technical field of nano pigments, in particular to a nano pigment YAl with high near-infrared reflection and good durability 1-x m x o 3 (M=Fe, Co, Cu) preparation method. 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 differen...
