Abstract

An anti-blue light resin monomer and an anti-blue light resin material polymerized by the monomer, the monomer is composed of quinophthalone compound shown in formula A, nano-titanium dioxide with core-shell structure, ultraviolet absorber and optical resin monomer according to The weight ratio is (0.1-0.2): (0.5-3.0): (0.2-2.0): (100-150). The preparation method comprises: adding quinophthalone compound (formula A) solution, core-shell structure nano-titanium dioxide and ultraviolet absorber to the polymer monomer for preparing the optical resin and mixing. The anti-blue light resin monomer and the anti-blue light resin material of the present invention have the performance of distinguishing and absorbing blue light in different bands, so that the harmful blue light in the middle and short bands can maintain low transmittance, and the beneficial blue light in the long band and visible light in other bands can maintain high transmittance. , is beneficial to protect eyesight, and better solves the problem of damage to human eyes caused by ultraviolet light and blue light.

Description

technical field [0001] The invention belongs to the technical field of light-absorbing materials, and in particular relates to a light-absorbing material with specific absorption wavelength in the 220-470nm spectral region, a precursor and a preparation method thereof. Background technique [0002] We all know that ultraviolet rays can damage people's eyes, but many people don't know that blue light in visible light can also cause damage to eyes. As part of visible light, blue light has extremely high energy, and its wavelength range is between 400 and 500nm. With the widespread popularization of electronic products such as computers, mobile phones, and ipads, unnatural light with blue light as the main body will cause irreversible damage to human eyes. Damage, causing dry eyes, fatigue, tearing, accelerated myopia, macular area disease and other problems. According to the orange warning issued by the World Health Organization (WHO) at the end of 2009: the potential invisib...
