The invention discloses ultraviolet light polymerization adhesive. The adhesive is prepared from 20-60 parts of matrix resin, 20-40 parts of auxiliary resin, 20-50 parts of active monomer diluent, 0.5-5 parts of photoinitiators and 0-10 parts of adhesion promoters. The matrix resin is polybutadience dimethacrylate, and the viscosity at the temperature of 50 DEG C ranges from 500 cps to 25000 cps; the auxiliary resin is either or both of aromatic urethane acrylate and epoxy acrylate, and the viscosity at the temperature of 50 DEG C ranges from 500 cps to 50000 cps. The ultraviolet light polymerization adhesive has the advantages of being high in bonding strength, good in toughness, good in dampness resistance and the like, and thereby the problem that an adhesive layer is prone to being hydrolyzed under the condition of high temperature and high humidity is solved; due to the fact that the adhesive is good in dampness resistance, after being immersed in boiling water for two hours, the tensile shearing strength of a bonded workpiece is still above 10 MPa. The adhesive can be widely applied to bonding of materials such as glass, crystals, colored glaze, jewels, plastic and rubber, in particular to bonding of home decoration glass materials.
