Abstract

The invention relates to a cationic bio-based polymer water-based dispersant which comprises a component of trimeric cardanol polyoxyethylene ether quaternary ammonium salt, is biodegradable and does not contain alkylphenol. The dispersant comprises an anchoring group trimer cardanol chain segment and a hydrophilic group polyoxyethylene ether quaternary ammonium salt chain segment, wherein the molar ratio of the anchoring group to the hydrophilic group is 1:(36-45). The water-based dispersant disclosed by the invention has the advantages of excellent emulsifying, wetting and dispersing performance, excellent water resistance, heat resistance and flexibility, stable high-concentration low-viscosity color paste, high degree of dyeing on lignin fibers and strong adsorption capacity. The water-based dispersant is suitable for preparing the water-based resin-free organic color paste, is particularly suitable for coloring fiber-containing materials, such as paper pulp coloring, cotton fiber coloring and blockboard coloring, and is high in color paste transfer rate and strong in color fastness. The water-based dispersant can also be used for green and environment-friendly products requiring no alkylphenol in the industries of coating color paste, printing color paste, papermaking color paste, cosmetic and daily necessity color paste, pesticide emulsification, detergent and the like.
