Abstract

The invention discloses a novel aqueous dispersant and a preparation method thereof, and application of the novel aqueous dispersant to dispersion containing solid particles, belonging to the field ofdispersants. The novel aqueous dispersant contains a solvation chain compatible with an aqueous solvent and an anchoring group with affinity to dispersed solid particles. The solvation chain and theanchoring group are conjugated via a covalent bond. The novel aqueous dispersant is applied to dispersion containing solid particles of organic pigment, inorganic pigment, filler, graphene or metal powder. The dispersion is liquid dispersion or solid dispersion such as printing ink, paint, plastics, color paste, pesticides, and jet ink for ceramics. The novel aqueous dispersant provided by the invention is capable of improving the dispersion stability of solid particles in an aqueous medium or enhancing the application performance of a disperse system, and can reduce pollution of volatile organic solvents in the disperse system to environment.

Description

technical field [0001] The invention relates to the technical field of dispersants, in particular to a novel water-based dispersant. Background technique [0002] When preparing liquid dispersions such as pigments, coatings, inks, paints, pesticides, etc. or solid dispersions such as plastics, in order to better disperse the solid particles in the carrier and obtain an ideally mixed and stable dispersion, it is necessary to use a Dispersant for ideal dispersing effect. [0003] The main disadvantages of currently used water-based dispersants are small molecular weight, weak anchoring ability to solid particles, and hydrophilic polyether chains cannot provide sufficient steric hindrance for solid particles. Contents of the invention [0004] The first technical problem to be solved by the present invention is to provide a new green and non-polluting water-based dispersant that has affinity for solid particles and water-based solvents at the same time, has a good dispersion...
