The invention belongs to the technical field of adhesives and relates to a polyether-type urethane acrylate UV-cured adhesive and a preparation method thereof. The polyether-type urethane acrylate UV-cured adhesive comprises, by weight, 20-70 parts of polyether-type urethane acrylate, 10-40 parts of auxiliary resin, 5-20 parts of ethylene-acrylate rubber, 5-40 parts of an acrylate monomer, 5-35 parts of isobornyl acrylate, 1-7 parts of a photoinitiator, 1-5 parts of fumed silica and 0.5-2 parts of a silane coupling agent. Through use of the polyether-type urethane acrylate, auxiliary resin, ethylene-acrylate rubber and acrylate monomer, the polyether-type urethane acrylate UV-cured adhesive has excellent long-term high temperature resistance, low temperature resistance, high temperature and high humidity resistance, excellent shock resistance and a low cost and can be prepared by simple processes.
