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 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 [00...
