Description

technical field [0001] The invention relates to the field of coatings, in particular to a UV LED low-energy curing household 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 curing energy to quickly crosslink 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, large heat generation, and low conversion rate of electric energy to ultraviolet light. Due to the large heat generation, it is easy to cause deformation or damage to the substrate. , High-pressure mercury lamps contain mercury, a toxic substance, and produce ozone, pollute the environment, and endanger health. [0003] Therefore, the prior art still needs to be further improved. SUMMARY OF THE INVENTION [0004] In view of the defi...
