Abstract

The invention relates to transparent nano-ferric oxide ink-jet color paste. The transparent nano-ferric oxide ink-jet color paste contains the following components in parts by weight: 30-35 parts of ferric oxide, 15-20 parts of a dispersing agent, 0.4-0.6 part of a pH adjuster, 0.2-0.4 part of a sterilizing agent and 45-55 parts of water. By utilizing a brand new processing process and equipment and a preferable color paste formula, the particle size of the color paste can reach the nanoscale, and the storage stability is good; and the color past is of a resin-free system, does not contain a solvent component, is environment-friendly and can be widely applied to various types of ink-jet coatings.

Example Embodiment

[0040] Example 1
[0041] Add 38.3% deionized water, 0.2% 1,3,5-tris(2-hydroxyethyl)-s-triazine, pH adjuster I 0.3% dimethylethanolamine, dispersant I 15% TEGO755W according to the weight ratio in Table 1 , After stirring evenly at a speed of 600r/min in a high-speed disperser, add 35% transparent iron oxide red pigment powder, disperse at a high speed of 800r/min for 60min, and use a pump to transport the slurry to a horizontal sand mill. Coarse grinding, using 0.6 zirconium beads as the grinding medium, grinding until the particle size of the color paste measured by the fineness scraper is less than 5um, pump the semi-finished color paste into the dispersing tank, add the remaining dispersant II 3% TEGO755W, and put it in a high-speed disperser. After re-dispersing at 800r/min for 60min, the slurry was pumped to the rod-pin horizontal sand mill for fine grinding. At this time, 0.3um zirconium beads were used as the grinding medium, and the grinding was carried out until the size determined by the particle size analyzer. After the color paste particle size reaches D95<0.3μm, pump the color paste to the material tank, add pH adjuster II 0.222% dimethylethanolamine and 8% deionized water at the speed of 600r/min of the high-speed disperser, stir for 30min, After the viscosity and fineness are qualified, the water-based nano transparent iron oxide red inkjet color paste is obtained by filtering and packaging.
