Preparation method for multipurpose iron oxide yellow water-based color paste

Abstract

The invention relates to a preparation method for a multipurpose iron oxide yellow water-based color paste. The basic formula of the water-based color paste involves: 12%-30% of water, 5-10% of a moisturizing agent, 1.5%-3% of a wetting agent, 4%-7% of a dispersing agent, 1.0%-1.5% of an AMP-95 assistant, 45%-65% of iron oxide yellow powder, 0.05%-0.3% of a thickening anti-settling agent, 0.1%-0.3% of a fungicide, and 0.1%-0.5% of a defoamer. With the characteristics of good storage stability, high tinting strength, and good compatibility, etc., the iron oxide yellow water-based color paste has high performance, economical efficiency and environmental friendliness, is a highly cost-effective multipurpose iron oxide yellow water-based color paste, and can be widely used in coloring of water-based architectural coatings, water-based wood coatings, water-based automobile coatings, water-based paper coatings, water-based plastic coatings, water-based glass coatings, water-based leather coatings and water-based ink, etc.

Description

technical field [0001] The invention relates to a preparation method of an iron oxide yellow water-based color paste, in particular to a multi-purpose, economical and high-performance iron oxide yellow water-based color paste. Background technique [0002] Water-based color paste is a coloring material, and its application fields are very wide, including paint, leather, ink, paper, latex, textile and other industries. 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 mont...

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%...
