Abstract
The invention relates to gluing process glue and a production process, and relates to the technical field of glue, the gluing process glue comprises the following components by mass: 50-60 parts of branched modified epoxy resin, 20-30 parts of a urethane acrylate prepolymer, 3-5 parts of a photoinitiator, 8-12 parts of a curing agent, 1-3 parts of a coupling agent, and 10-15 parts of a filler. The production process comprises the following steps: adding a polyurethane acrylate prepolymer, a filler and a coupling agent into branched modified epoxy resin in a stirring process, and stirring to obtain a mixture; and adding a photoinitiator and a curing agent into the mixture, increasing the rotating speed, stirring, and defoaming to obtain the glue for the gluing process. The application has the effect of improving the adhesion performance of the glue, the glue has a low shrinkage rate, and the glue is used for the gluing process of lenses and the fixed assembly of two lenses, so that the phenomenon of aperture deformation can be reduced, and the product quality can be improved.
