The invention discloses a low-energy curable in-half-foldable high-abrasion-resistant UV coating which comprises a component A and a component B. The component A contains, by mass, the raw materials:30-40 parts of an organic-inorganic hybrid material, 15-20 parts of a urethane acrylate oligomer with the low functionality degree of 6-10, 10-15 parts of a urethane acrylate oligomer with the functionality degree of 2, 5-10 parts of a monomer with the functionality degree of 2-6, 10-15 parts of an ester solvent, 5-10 parts of an alcohol solvent and 0.1-0.5 part of a leveling aid; the component Bcontains, by mass, the raw materials: 40-50 parts of a photoinitiator, 1-5 parts of a mercaptan assistant and 45-55 parts of an ester solvent. According to the invention, the organic-inorganic hybridmaterial is adopted, so that the coating has high abrasion resistance and good flexibility, and meanwhile, the mercaptan assistant is mixed to improve oxygen polymerization resistance, so that the coating can achieve a good cur
