Abstract

The invention discloses pigment red 112 dispersions and a preparation method thereof. The dispersions comprise pigment red 112, a surfactant, a high molecular polymer, an addition agent and the like. The preparation method comprises the following steps that 1, the pigment red 112, sodium diethylhexyl sulfosuccinate, cocodimethylamine, etidronic acid, isopropyl myristate are taken by weight, mechanically mixed and stirred until smooth; 2, isotridecyl myristate, polyvinylpyrrolidone, polyepoxysuccinic acid, sodium carboxymethyl starch and water are added and stirred until smooth; 3, mixed components which are stirred evenly in the step 2 are cooled to the room temperature, mixed dispersions are sheared, and after shearing is finished, the pigment red 112 dispersions are obtained. The prepared pigment red 112 dispersions have the better dispersity and stability, and can be applied to water-based ink and coating.

Description

Technical field [0001] The invention belongs to the field of pigments, and relates to a pigment dispersion and a preparation method thereof, in particular to a pigment red 112 dispersion and a preparation method thereof. Background technique [0002] Pigment Red 112 is a bright neutral red, used in various printing inks. The specific surface area of ​​PR.112 is 17M2 / G, which has high color strength and excellent light fastness) 1 / 1SD level 6); The lightfastness of the printing paste is grade 7, but the dry cleaning resistance is slightly worse; it is used for air-drying paints and baked enamels, and the light resistance is 7-8, and the dilute color is 6-7. It can be used for high-end automotive coatings and latex. Lacquer; mixed with Pigment Yellow 83 and Pigment Violet 23 for wood coloring. Water-based paints and water-based inks are required to have the same fluidity, storage stability, film gloss, vividness, and tinting power as oil-based paints and oil-based inks. [0003] Ho...
