▎ 摘  要

NOVELTY - Preparing ultraviolet curing adhesive comprises e.g. preparing modified graphene color paste after mixing ultraviolet resin and graphene, stirring and ultrasonically dispersing, mixing surfactant and leveling agent, pouring into mixture A, firstly stirring, cooling, heating, finally performing third stirring, preparing raw materials for ultraviolet curing adhesive includes prepolymer, active monomer, photoinitiator, modified graphene color paste, urethane acrylate, polyacrylamide, and auxiliaries, adding active monomer and prepolymer to container, uniformly stirring until colloid is clear and transparent, adding auxiliary, uniformly stirring, adding urethane acrylate, polyacrylamide, photoinitiator, and modified graphene color paste, stirring under condition of avoiding light to obtain ultraviolet curing adhesive. USE - The method is useful in preparing ultraviolet curing adhesive for solar cell (claimed). ADVANTAGE - The adhesive: contains polyurethane acrylate and polyacrylamide, which has good abrasion resistance, toughness, and solvent resistance; contains monomer and prepolymer are polymerized and crosslinked to form network structure, which has excellent gloss, color retention, strength, chemical resistance, water resistance and weather resistance; and contains modified graphene color paste, which improves adhesion to substrate, and improves leveling property. DETAILED DESCRIPTION - Preparing ultraviolet curing adhesive comprises (i) preparing modified graphene color paste after mixing ultraviolet resin and graphene, stirring and ultrasonically dispersing at 40-50 degrees C for 1-3 hours to obtain mixture A, mixing surfactant and leveling agent at 20-30 degrees C, then pouring into mixture A, firstly stirring at 20-30 degrees C, cooling to 10-20 degrees C, heating to 20-30 degrees C for second stirring, finally performing third stirring at 10-20 degrees C to obtain modified graphene color paste, (ii) preparing raw materials for ultraviolet curing adhesive includes 35-40 pts. wt. prepolymer, 52-58 pts. wt. active monomer, 1-5 pts. wt. photoinitiator, 2-6 pts. wt. modified graphene color paste, 25-45 pts. wt. urethane acrylate, 5-15 pts. wt. polyacrylamide, and 2-8 pts. wt. auxiliaries, and (iii) preparing ultraviolet curable adhesive by adding active monomer and prepolymer to container, uniformly stirring until colloid is clear and transparent, adding auxiliary, uniformly stirring, adding urethane acrylate, polyacrylamide, photoinitiator, and modified graphene color paste, stirring for 20-30 hours under condition of avoiding light to obtain ultraviolet curing adhesive.
