Abstract

The invention discloses a vegetable oil-based hydrophilic polymer water dispersion and its preparation method and application. The method firstly uses ricinoleic acid and mercaptocarboxylic acid as raw materials to prepare castor oil-based hydrophilic monomer; then uses vegetable oleic acid and acrylate as raw materials to prepare vegetable oil-based acrylate monomer; and then uses castor oil-based hydrophilic monomer, vegetable oil The base acrylate monomer, other monomers, chain transfer agent and part of the initiator are mixed uniformly to obtain a mixed solution, and part of the mixed solution is reacted to prepare seeds, and then the remaining amount of the mixed solution is added dropwise to the reaction system for reaction to prepare vegetable oil-based proteases. water-based polymer; finally, distillation under reduced pressure, neutralization, and dispersion with water to obtain a vegetable oil-based hydrophilic polymer water dispersion. The present invention uses plant carbon sources to replace more than half of the petroleum-based carbon sources, thereby reducing the pressure on petrochemical resources; reducing the usage of acrylate-based volatile monomers, reducing VOC emissions, and eliminating irritating volatiles for operators bodily injury.

Description

technical field [0001] The invention belongs to the technical field of organic polymer materials, and particularly relates to an aqueous vegetable oil-based hydrophilic polymer dispersion and a preparation method and application thereof. Background technique [0002] Compared with traditional solvent-based coatings, water-based coatings have the advantages of low price, safe use, saving resources and energy, reducing environmental pollution and pollution, and thus have become the main development direction of the current coatings industry. Water-based acrylic resin coatings are the fastest-growing and most diverse non-polluting coatings in water-based coatings. In recent years, the development and application of acrylic resin water dispersion has attracted more and more attention, and its application in the field of industrial coatings and civil coatings has been continuously expanded. According to the monomer composition, it is usually divided into pure acrylic emulsion, s...
