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 type of color paste has poor stability and breaks down after long-term storage (about 2 months). 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

Embodiment 1

[0014] A multi-purpose iron oxide red water-based color paste is composed according to the weight ratio of raw materials: 10%-25% of water, 3%-10% of humectant, 1.5%-3% of wetting agent, 3%-7% of dispersant, AMP -95 multifunctional additive 0.3%~0.6%, iron oxide red powder 40%~70%, thickening and anti-settling agent 0.3%~1.0%, fungicide 0.1%~0.3%, defoamer 0.1%~0.5%.

[0015] Preparation process: Add deionized water, humectant, wetting agent, dispersant, and pH regulator according to the weight ratio of the formula, stir evenly in a high-speed disperser at a speed of 500r / min, and then mix at a high speed of 1000-1200r / min Add iron oxide red powder at low speed, disperse at high speed for 45 minutes, and then grind 3 to 4 times until the fineness is qualified. After foaming agent, viscosity and fineness are qualified, filter and pack to obtain iron oxide red water-based color paste.

Abstract

The invention relates to a preparation method for a multi-purpose iron oxide red water-based color paste. The basic formula of the water-based color paste involves: 10%-25% of water, 3%-10% of a moisturizing agent, 1.5%-3% of a wetting agent, 3%-7% of a dispersing agent, 0.3%-0.6% of an AMP-95 assistant, 40%-70% of iron oxide red powder, 0.3%-1.0% of a thickening anti-settling agent, 0.1%-0.3% of a fungicide, and 0.1%-0.5% of a defoaming agent. With the characteristics of good storage stability, high tinting strength, and good compatibility, etc., the iron oxide red water-based color paste has high performance, economical efficiency and environmental friendliness, is a highly cost-effective multi-purpose iron oxide red 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 iron oxide red water-based color paste, in particular to a multi-purpose, economical and high-performance iron oxide red 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.
