Abstract

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.

Description

technical field [0001] The invention mainly relates to the field of ultraviolet curing materials, in particular to an ultraviolet (UV) curing coating for PVC material film coating process and a preparation method thereof. Background technique [0002] Traditional non-UV coatings have a slow curing speed, seriously affecting production efficiency, and traditional non-UV coatings contain a large amount of volatile organic solvents, which are not only extremely harmful to human health, but also cause serious environmental problems due to volatilization into the atmosphere after use. pollution. UV coatings are composed of UV-curable resins, reactive diluents, photoinitiators, additives and other components, which can avoid the use of volatile organic solvents, and are an important development direction of environmentally friendly coatings. With the improvement of people's awareness of environmental protection, the application field and market demand of UV paint will continue to...
