Abstract

The invention provides waterborne photo-curing resin and application thereof, and belongs to the technical field of a coating material and an adhesive. A technical scheme is characterized by polymerizing monomers containing C-C double bonds through free radicals, thus obtaining an acrylate prepolymer; linking the C-C double bonds to a polymer structure, and then carrying out neutralization and water dispersion, thus obtaining a product. According to the waterborne photo-curing resin and the application thereof, provided by the invention, the waterborne photo-curing resin can be conveniently and quickly prepared by emulsifyinng a traditional photo-curing monomer or prepolymer in a prepared acrylate water dispersion; a main component of the waterborne photo-curing resin is an acrylate polymer, and a curing coating layer has good weather resistance and good boiling stability; in the waterborne photo-curing resin prepared by adopting the technical scheme, the solid content can be up to 50percent, and the viscosity is low; through formula design, the waterborne photo-curing resin can be widely applied to the fields of waterborne coating materials and adhesives.

Description

technical field [0001] The invention relates to the technical field of coatings and adhesives, and further relates to the improvement of a preparation method of a water-based photocurable resin, in particular to a water-based photocurable resin and its application. Background technique [0002] Photocurable resins, also known as UV-curable resins, are mainly composed of macromolecular oligomers, which generally have a relatively high viscosity. Therefore, reactive diluents must be added to adjust their viscosity and rheology when used as coatings. Because reactive diluents generally contain VOCs, and have varying degrees of toxicity and irritation, there are certain hazards to the human body and the environment. Water-based photocurable resin is a kind of photocurable resin material that can use water as the dispersion medium. Since the use of active diluent is avoided, there is no VOC emission, and it has the advantages of safety and environmental protection. [0003] In t...
