Problems solved by technology

In this way, it will inevitably cause the complexity of the process and the relatively expensive raw materials, and when used, there will be poor selective adsorption of specific pigments, or it will be absorbed by the polar solvent in the system or other polar groups present in the system. Adsorbed anchor groups are displaced from the surface of the particles, resulting in ineffective dispersion, which eventually causes the system to flocculate and agglomerate again

Abstract

The invention provides an amide-containing polymer, which is polymerized by monomer with reactive amino-group or imino group and monomer with carboxyl group or carboxyl derivatives. The prepared polymer is once more polymerized with one or more monomers of alpha, beta-unsaturated carbonyl compounds, aliphatic acid and derivatives thereof or epoxide; and the prepared polymer is used as pigment, powder, fiber and other dispersant and dispersion stabilizer in a urethane resin system, an acrylic resin system, an alkyd resin system and a melamine resin system.

Description

technical field [0001] The present invention relates to a synthetic polymer, especially an amide-containing polymer, and its use as a dispersant and dispersion stabilizer in pigments, powders and fibers. Background technique [0002] In order to uniformly disperse pigments, solid powders or fibers into fluids, strong mechanical shearing and stirring are generally required. After the dispersion operation, due to the small particle size and large surface energy of the dispersed powder material, it shows a strong agglomeration phenomenon, which leads to the increase of the viscosity of the system and the decrease of fluidity, and in severe cases, it cannot be used continuously. To solve this problem, it is necessary to add a dispersant in the production process of the product. It can not only simplify the dispersion process, but also change the physical state of the particle surface, so that the fluid can maintain good stability during storage and transportation, and prevent th...
