The invention discloses anti-ultraviolet urethane acrylate waterborne coating adhesive and the preparation method; the urethane acrylate emulsion in the prior art cannot have the anti-ultraviolet function and can only be applicable to the weaving coating field. The invention adopts the means of molecular structure design that firstly, the group with the anti-ultraviolet function is introduced to acrylic ester emulsion to prepare the acrylic ester emulsion with the anti-ultraviolet function, and then the means of molecular structure design is adopted to prepare polyurethane emulsion with double bond; the interpenetrating polymer networks method is adopted to process copolymerization of the two emulsions to obtain the anti-ultraviolet urethane acrylate waterborne coating adhesive with the interpenetrating polymer networks structure. The waterborne coating adhesive in the invention has the properties of PU property, PA property and anti-ultraviolet property and extends the application range of the coating adhesive, enabling the coating adhesive not only to be applicable to the weaving coating field, but also to be applicable to the fields of paper-making, coating, packaging and leather.
