Problems solved by technology

[0002] With the improvement of industry and people's living standards, the application of pigments and inks is becoming more and more extensive. Due to the low polarity of the surface of pigments and ink particles, it is not easy to disperse stably in the water medium, which leads to the problem of solid content in the product and the generation of particles. Therefore, people adopt dispersants to improve the dispersion performance of pigments and printing inks, but the general dispersion performance of dispersants on the market is relatively weak, which affects the quality of products.

Abstract

The invention discloses an aqueous polymer dispersant, and belongs to the field of polymer materials. The aqueous polymer dispersant is mainly formed by acrylic acid, a styrene-butadiene copolymer, astrong oxidant, a pH value blender and an initiating agent. In the aqueous polymer dispersant, a benzene ring of the styrene-butadiene copolymer is firmly bonded with an aromatic ring in a pigment molecule, so that the aqueous polymer dispersant is not separated from the surface of pigment easily; the proportion of hydrophilcity and hydrophobicity is moderate, so that the aqueous polymer dispersant can be well spread in water and is relatively strong in binding force with paint, therefore, the dispersing capacity of the aqueous polymer dispersant is relatively high, the dispersing performancesof the pigment and printing ink can be effectively improved, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a water-based polymer dispersant. Background technique [0002] With the improvement of industry and people's living standards, the application of pigments and inks is becoming more and more extensive. Due to the low polarity of the surface of pigments and ink particles, it is not easy to disperse stably in the water medium, which leads to the problem of solid content in the product and the generation of particles. Therefore, people adopt dispersants to improve the dispersion performance of pigments and printing inks, but the general dispersion performance of dispersants on the market is relatively weak, which affects the quality of products. Deficiencies of dispersants. Contents of the invention [0003] The object of the present invention is to provide a water-based polymer dispersant to solve the problems raised in the above-mentioned background techno...
