Abstract

The invention provides UV LED low-energy curing ceramic paint and a preparation method thereof. The UV LED low-energy curing ceramic paint is prepared from, by mass, 32-37 parts of aliphatic polyurethane hexaacrylate oligomer, 13-18 parts of modified epoxy acrylate oligomer, 28-33 parts of trimethylolpropane triacrylate, 8-12 parts of pure acrylate resin, 2-5 parts of photoinitiator, 3-7 parts of active ammonia coinitiator and 0.5-1 part of auxiliary. The ceramic paint effectively utilizes a UV LED to serve as an ultraviolet light source to conduct rapid curing and has the advantages of being capable of reducing energy consumption and use cost and environmentally friendly, the curing speed of the paint is high, and the formed film is high in hardness, high in weather resistance, good in smoothness and high in adhesion on ceramic.

Description

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