Problems solved by technology

Due to the high molecular hardness of iron oxide pigment dry powder, it is not suitable for grinding and dispersing due to its large specificity. Therefore, the produced iron oxide pigment water-based color paste has coarse particles, 15-20 microns, easy to precipitate, and poor coloring power.

Abstract

The invention relates to a preparation method of an iron oxide water-based color paste, which comprises the following steps: (1) stirring undried iron oxide pigment, and heating to 65-75 DEG C; (2) dropwisely adding 3-6 parts by weight of anionic active agent and 4-8 parts by weight of high-performance dispersing agent, keeping the temperature at 65-75 DEG C, and continuously stirring; (3) adding 2-3 parts by weight of supplementary wetting agent, keeping the temperature at 65-75 DEG C, and continuously stirring; (4) after bubbles appear, cooling to room temperature; (5) adding 0.3-0.5 part by weight of defoaming agent; and (6) adding deionized water to obtain the iron oxide water-based color paste. According to the invention, the prepared iron oxide pigment has high dispersity, fine granularity and strong coloring power.

Description

technical field [0001] The invention relates to the field of pigments, in particular to a preparation method of iron oxide water-based color paste. technical background [0002] Water-based color paste has a wide range of uses. It only needs to directly add water-based color paste to the prepared base material to efficiently produce various colors of coatings, inks and textile printing materials. Widely used in coatings, leather, printing, paper making, latex, textile and other industries. [0003] The iron oxide series pigment water-based color paste currently produced and sold on the market is made of iron oxide pigment dry powder by adding additives and water using a physical colloidal grinding process, that is, sanding with a sander for multiple times. Due to the high molecular hardness of iron oxide pigment dry powder, it is not suitable for grinding and dispersing due to its large specificity. Therefore, the produced iron oxide pigment water-based color paste has coar...
