Abstract

The invention provides a UV LED low-energy curing cabinet coating and a preparation method thereof. The UV LED low-energy curing cabinet coating is prepared from the following components in parts by mass: 8-12 parts of polyurethane hexaacrylate, 25-30 parts of modified epoxy acrylate oligomer, 30-35 parts of trimethylolpropane triacrylate, 0.2-0.4 part of fumed silica, 2-5 parts of photoinitiator, 3-7 parts of active ammonia co-initiator, 18-23 parts of R706 titanium dioxide and 0.6-1 part of auxiliary. The cabinet 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 moreover, the curing speed of the coating is high, the formed film has good smoothness, strong adhesion on a cabinet and good waterproof property.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a UV LED low-energy curing cabinet 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 invention [0004...
