Abstract

The invention discloses a vegetable oil-based polyacrylate nonionic emulsion, a preparation method and application thereof. The method first uses vegetable oleic acid and acrylate as raw materials to prepare vegetable oil-based acrylate monomers; then, according to the formula, mix vegetable oil-based acrylate monomers, hydrophilic monomers, other monomers, chain transfer agents and some initiators evenly To obtain the mixed solution, preheat part of the mixed solution to prepare the reaction "seed", then drop the remaining amount of the mixed solution into the reaction system, and keep it warm for 1 to 2 hours; add the remaining amount of initiator to the reaction system to continue the reaction, and obtain Vegetable oil-based polyacrylate with molecular brush structure; finally remove the solvent by distillation under reduced pressure, add water to stir and disperse to obtain vegetable oil-based polyacrylate non-ionic emulsion. On the one hand, the method of the invention can ensure that the prepared polymer has sufficient hydrophilicity; on the other hand, it avoids the use of acrylic hydrophilic monomers with volatile and pungent odors, so that the odor-free polymer emulsion can be prepared.

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 nonionic emulsion and a preparation method and application thereof. Background technique [0002] Water-based technology refers to the science and technology that uses water instead of organic solvents to study the preparation and application of polymer materials. Polymers prepared with water instead of organic solvents are collectively referred to as water-based polymers, which are non-toxic, odorless and pollution-free, and are one of the important directions for the development of polymer materials. Common water-based polymer materials include water-based acrylic resin, water-based polyurethane, water-based alkyd resin, water-based epoxy resin, etc., the most representative of which are water-based acrylic resin and water-based polyurethane. Water-based acrylate is divided into two types according to its dispers...
