The invention relates to a preparation method of a novel dual-cured UV curing binder, and belongs to the technical field of binder industry. The novel dual-cured UV curable binder is prepared by using radical polymerizable resins such as common urethane acrylate, epoxy acrylate and unsaturated polyester as main binding materials, using a double bond-containing reactive diluent as a solvent, and using a UV initiator and a thermal initiator as a compound initiator, supplemented by other binding agents. During curing, a certain initial binding power is firstly obtained by UV curing, and higher binding power is obtained by secondary curing through heating or oxygen isolation. The preparation method provided by the invention not only has the advantages of high curing speed of the traditional light curing binders, but also has the advantages of effectively avoiding the generation of internal stress in the curing process of the traditional light curing binder, and improving the binding strength of the binder; the binder has excellent solvent resistance, high binding strength, and low cost. The binder is widely used for binding glass and glass, glass and metal materials and other transparent materials.
