Abstract

The invention belongs to the field of nano-materials and relates to nanometer alumina condensate paste and a preparation method thereof. The nanometer alumina condensate paste comprises 100 parts of nanometer alumina with primary particle average particle sizes of 50nm or less, 5-10 parts of an organic corrosion inhibitor, 0.1-0.3 parts of an antirust pigment, 0.3-0.6 parts of an auxiliary agent and 15-20 parts of an organic solvent. The preparation method comprises weighing the above materials according to the above ratio, uniformly mixing the organic corrosion inhibitor, the antirust pigment, the auxiliary agent and the organic solvent, gradually adding nanometer alumina powder into the mixture under the condition of continuous rotation of a high-rate dispenser, after all the nanometer alumina powder is added into the mixture, carrying out dispersion at a dispenser rotating speed of 1500-2500rpm for 5-30min, and grinding the nanometer alumina slurry through a ball mill or a sand milling machine for 1-10h so that the average particle size is 100nm or less and the nanometer alumina condensate paste is obtained. The nanometer alumina condensate paste has good dispersibility, storage stability, high solid content, low viscosity, good compatibility and anticorrosion functions.

Description

technical field [0001] The invention belongs to the field of nanometer materials, in particular to a concentrated nano-alumina slurry and a preparation method thereof. Background technique [0002] Nano-alumina has important applications in ceramics, coatings, fibers, rubber and other fields. It has been found that nano-Al 2 o 3 The powder has a strong absorption capacity for ultraviolet light below 250nm. If it is added to the coating, it may improve the anti-aging ability of the organic coating; if it is added to rubber or plastic, it can improve their wear resistance; if it is added to sunscreen oil , cosmetics, it can improve its anti-ultraviolet performance. containing nano-Al 2 o 3 Clothes made of fiber have infrared absorption function. At the same time nano-Al 2 o 3 The polishing liquid can also be used for polishing high-grade optical glass and precious stones. However, due to the large specific surface area and many suspended bonds on the surface of nano-a...
