Abstract

The invention discloses a pigment yellow 38 emulsion and a preparation method thereof. The emulsion comprises 10-18 parts of pigment yellow 38, 3-8 parts of polyethylene glycol distearate, 4-10 parts of lauryl dimethyl amine oxide, 3-7 parts of lauric isopropanolamide, 2-5 parts of 1-hydroxyethylidene-1,1-diphosphonic acid, 4-9 parts of carboxylmethylhydroxypropyl guar gum, 3-8 parts of 1,2-propanediol, 3-10 parts of di-isooctyl sodium sulfosuccinate and 300-500 parts of water. The preparation method comprises the following steps: (1) grinding pigment yellow 38; (2) mixing and stirring pigment yellow, polyethylene glycol distearate, lauryl dimethyl amine oxide, lauric isopropanolamide and 1-hydroxyethylidene-1,1-diphosphonic acid; and (3) stirring carboxylmethylhydroxypropyl guar gum, 1,2-propanediol, di-isooctyl sodium sulfosuccinate and water, thus preparing the pigment yellow 38 emulsion. The prepared pigment yellow 38 emulsion has the characteristics of good stability and easiness in dispersion.

Description

technical field [0001] The invention belongs to the field of pigments, and relates to a pigment yellow 38 emulsion and a preparation method thereof. Background technique [0002] Pigment is a kind of colored fine particle powder substance, which is generally insoluble in water, oil, solvent and resin, and can be dispersed in various media. It has hiding power, tinting power, and is relatively stable to light. It is often used to prepare paints, inks, and colored plastics and rubbers, so it can also be called a colorant. Pigments are different from dyes in that dyes are generally soluble in water (old distinction), while pigments are generally insoluble in water. Dyes are mainly used for dyeing materials such as textiles. However, this distinction is not very clear, because some dyes may also be insoluble in water, and pigments are also used for pigment printing and original coloring of textiles. The chemical structure of organic pigments is similar to that of organic dyes...
