Abstract

The invention discloses a nano zirconia alcohol slurry and a preparation method thereof. The nano zirconia alcohol slurry comprises, by weight, 1-60 parts of nanometer level ZrO2 powder, 0.05-10 parts of dispersant and 30-99 parts of solvent. The preparation method is as below: the dispersant is added and dissolved in the organic solvent; then the nanometer level ZrO2 powder is added in the mixture and dispersed by a high speed bowl mill for 0.2-10 h, so as to obtain the oil slurry. The technology of the invention is simple, has a short processing time, easily controlled process and high application value. The nano zirconia slurry prepared by the invention is a highly decentralized, uniformized and stabilized slurry, can be widely applied to fields of high strength and high-toughness wear resistant product, functional ceramic, structural ceramic, electric device and refractory material, etc.

Description

technical field [0001] The invention relates to a nanometer material and a preparation method thereof, in particular to a nanometer zirconia oily slurry and a preparation method thereof. Background technique [0002] Nano-zirconia is an important inorganic functional material, which is widely used in precision structural ceramics, functional ceramics, nano-catalysts, solid fuel cell materials, functional coating materials, advanced refractories, optical fiber connectors, mechanical ceramic seals, high Wear-resistant ceramic balls, nozzles, spray sheets and other industrial fields. However, due to the small size of nano-zirconia powder particles, there are stronger interaction forces between particles than micron-sized powders, such as electrostatic force, van der Waals force, capillary force, mechanical entanglement force, etc. Due to the disadvantages of poor fluidity, the nanoparticles cannot be well dispersed, which seriously affects the performance of the powder. For e...
