Abstract

The invention provides an anti-blue-light coating composition, a preparation method thereof and an anti-blue-light material. The blue light resistant coating composition comprises the following components in parts by weight: 30-80 parts of resin, 3-8 parts of a blue light absorbent, 3-8 parts of an ultraviolet absorbent, 3-6 parts of a photoinitiator and 3-8 parts of an auxiliary agent, and the solid content of the solvent coating composition is kept at 20-70 wt%. The prepared coating composition is excellent in blue light resistance and ultraviolet resistance and has the advantages of being high in mechanical property, high in adhesion and high in hardness.

Description

technical field [0001] The invention belongs to the technical field of anti-blue light materials, and relates to an anti-blue light coating composition and a preparation method thereof, and an anti-blue light material. Background technique [0002] With the rapid development of science and technology, digital display plays an increasingly important role in human production and life in today's society, greatly accelerating the efficiency and convenience of life, and greatly changing human living habits, such as People are spending more and more time accessing information through their mobile phones or tablets. [0003] However, the blue light generated by the digital display can affect human health. Short-wave blue light is light with relatively high energy wavelengths between 400nm-480nm. Due to the short wavelength, high frequency and high energy of blue light, lutein in the naked eye generates free radicals after absorbing blue light. Free radicals will cause the epitheli...
