Abstract

The invention discloses a vegetable oil-based polyacrylate anionic emulsion as well as a preparation method and application thereof. The preparation method comprises the following steps: preparing a vegetable oil-based acrylate monomer, then uniformly mixing the vegetable oil-based acrylate monomer, other monomers, a chain transfer agent and a part of an initiator according to a formula to obtain a mixed solution, adding a part of the total amount of the mixed solution into a preheated solvent and reacting for a period of time; dropwise adding the rest of the mixed solution into a reaction system, carrying out a heat preservation reaction, then, adding the rest of the initiator into the reaction system, carrying out a heat preservation reaction, and then performing cooling; adding a sulfydryl monomer and a photoinitiator, and reacting in a photochemical reactor for 3-5 hours; and performing reduced pressure distillation to remove the solvent, then adding water, stirring and dispersing, and adding a neutralizer for neutralizing while dispersing, thereby obtaining the vegetable oil-based polyacrylate anionic emulsion. The natural renewable vegetable oil is used for replacing the traditional acrylate monomer to prepare the high-molecular polymer, so that the pressure of petrochemical resources is reduced, and the additional value of the vegetable oil is improved.

Description

technical field [0001] The invention belongs to the technical field of organic polymer materials, and in particular relates to a vegetable oil-based polyacrylate anion emulsion and a preparation method and application thereof. Background technique [0002] Waterborne acrylic resins include acrylic resin emulsions, acrylic resin aqueous dispersions and acrylic resin aqueous solutions. Emulsions are mainly synthesized by emulsifying oily ethylenic monomers in water under the initiation of water-based free radical initiators, while resin aqueous dispersions are synthesized by different processes such as free radical solution polymerization or stepwise solution polymerization. Solution polymerization refers to a polymerization reaction in which monomers are dissolved in an appropriate solvent and an initiator is added in a solution state. It is an important synthetic method in the process of polymer synthesis. Generally, it is carried out at the reflux temperature of the solven...
