Problems solved by technology

Most of the currently produced water-based iron oxide color pastes are used for the coloring of latex paints for architectural coatings. For example, application numbers 03102844.6, 03132933.0, 03106999.1 and 200510120763.0 all belong to this type of color paste. The main components are dispersants, defoamers, iron oxide pigments, Preservatives, thickeners and water have good compatibility with latex paints. Most of the dispersants are polyacrylic acid sodium salts or ammonium salts. This kind of color paste has poor stability in long-term storage (about 1 month). Severe water, hard precipitation; using polyacrylic acid sodium salt or ammonium salt as dispersant, there is a higher selection of iron oxide pigments, the cost will increase by about 40%, and the economy is incomparable
Moreover, this kind of color paste is not suitable for water-based wood coatings, water-based automotive coatings, water-based paper coatings, water-based plastic coatings, water-based glass coatings, etc., and has coating disadvantages such as poor compatibility, floating color and fading.
At present, water-based wood coatings, water-based automotive coatings, water-based paper coatings, water-based plastic coatings, and water-based glass coatings have higher and higher requirements for the performance and environmental protection standards of colorants. To meet the requirements of such colorants, high-performance dispersants must be selected. Such as BYK190, TEGO750W, etc., their cost performance does not meet market demand

Abstract

The invention discloses aqueous iron oxide yellow color paste and a preparation method thereof. The aqueous iron oxide yellow color paste comprises 15 to 30% of water, 5 to 10% of a humectant, 1.5 to5% of a wetting agent, 4 to 7% of a dispersant, 1.0 to 1.5% of an AMP-95 auxiliary agent, 45 to 65% of iron oxide yellow powder, 0.05 to 0.3% of a thickening and anti-settling agent, 0.1 to 0.4% of abactericide and 0.1 to 0.8% of an antifoaming agent. The preparation method comprises the following steps: adding deionized water, the humectant, the wetting agent, the dispersant and a pH adjusting agent, carryign out uniform mixing in a high-speed dispersing machine at a speed of 500 r / min under stirring, then adding the iron oxide yellow powder at a high speed of 1000 to 1200 r / min, carrying out high speed dispersion for 45min, and then grinding the iron oxide yellow powder 3-4 times until the fineness of the iron oxide yellow powder is qualified, adding the thickening and anti-settling agent at a speed of 800 to 1000 r / min, carrying out stirring for 15-20 min until a particle-free uniform state is reached, adding the bactericide and the antifoaming agent at a low speed, and carrying out filtering and packaging after viscosity and fineness are qualified so as to obtain the aqueous iron oxide yellow color paste. The aqueous iron oxide yellow color paste prepared in the invention hasthe characteristics of good storage stability, high coloring power, good compatibility and the like, and has high performance, economic performance and environmental protection performance.
