UV curing coating for PVC material coating process and preparation method for UV curing material

The invention discloses an ultraviolet (UV) curing coating for a PVC material coating process and a preparation method for the UV curing material. The UV curing coating for the PVC material coating process is composed of the following raw materials in percentage by mass: 20-30% of modified epoxy acrylate, 35-40% of special functional group acrylate, 8-15% of aliphatic polyurethane acrylate, 20-30% of a reactive diluent, 6-10% of a photoinitiator and 0.3-1% of an additive. The UV curing coating for the PVC material coating process finishes coating only by one coating process and is quickly cured to form a film under UV-irradiation; the coating forming the film is good in adhesion, high in hardness, controllable in luster, good in scratch resistance, excellent in yellowing resistance and excellent in water resistance; and compared with a conventional process, the process has the advantages that the efficiency is high, intermittent production can be realized, the finished product defect rate is low and the like.
