| titleOfInvention | A kind of preparation method of pearl pigment |
| abstract | The invention relates to the field of pigment production, in particular to a method for preparing pearl pigments, comprising the following steps: heating 45-320ml of distilled water in a container to 40-60°C; dissolving 5-65g of bismuth nitrate in 120ml of distilled water to prepare bismuth Salt solution; inject bismuth salt solution into distilled water at a speed of 2-3ml/min, and at the same time inject chlorine and oxygen into distilled water through an air mixer at a speed of 0.1-0.2ml/min, and keep the reaction for 30-60min; Move the crystals to another container, add 400-500ml of distilled water, then add 2-5% aqueous surfactant diluent in the container, stir at a speed of 80rpm for 30min, discard the upper layer solution, and obtain the surface-activated crystals of the lower layer. The method of the invention is simple, effectively avoids the problem of environmental pollution caused by the use of organic solvents in the production and application of pearl pigments, and the prepared pearl pigments have good dispersibility, uniform coloring and good gloss in coatings and other attachments, and have potential market value . |
