Abstract

The invention provides a UV LED low-energy curing decorative material coating and a preparation method thereof. The UV LED low-energy curing decorative material coating is prepared from the following components in parts by mass: 27-31 parts of aliphatic polyurethane hexaacrylate oligomer, 12-17 parts of modified epoxy acrylate oligomer, 28-33 parts of trimethylolpropane triacrylate, 10-15 parts of polyester acrylate resin, 2-6 parts of photoinitiator, 3-7 parts of active ammonia co-initiator and 0.5-1 part of auxiliary. The UV LED low-energy curing decorative material coating is quickly cured by effectively utilizing UV LED as an ultraviolet light source and has the characteristics of energy consumption reduction, using cost lowering and environment friendliness; and the curing speed of the coating is high, and the formed film has the advantages of strong hardness, good smoothness, perfect aesthetics and strong adhesion on a decorative material.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a UV LED low-energy curing decorative material coating and a preparation method thereof. Background technique [0002] Traditional UV coatings refer to UV curable resin UV coatings, that is, resin UV coatings that use ultraviolet rays as a curing energy source to quickly cross-link and form films at room temperature. However, the traditional UV light sources are mainly high-pressure mercury lamps and metal halide lamps, which have the disadvantages of large power consumption, high heat generation, and low conversion rate of electric energy to ultraviolet rays. Due to the large heat generation, it is easy to cause deformation or damage of the substrate. In addition, , High-pressure mercury lamps contain the toxic substance mercury, and produce ozone, which pollutes the environment and endangers health. [0003] Therefore, prior art still needs further improvement. Contents of the invent...
