Abstract

An anti-blue light coating liquid, an anti-blue light coating optical material and a preparation method thereof, the coating liquid is composed of polythiourethane monomer, polyurethane / light absorber / titanium oxide nanocomposite microspheres, and isocyanate curing agent and diluent composition. Among them, the nano-composite microsphere has a three-layer composite core-shell structure, the inner core is titanium oxide nano-microspheres, the middle layer is a light absorber, and the outer shell is polyurethane. The coating liquid is coated on the optical material as an anti-blue light optical material, and its blocking spectrum extends from the ultraviolet spectral region to the blue light spectral region. While maintaining a high transmittance, it has the ability to distinguish and absorb blue light in different bands , wherein the 280-380nm ultraviolet transmittance is less than 1%, the 400-440nm short-wave blue light transmittance is less than 5%, and the 460-500nm blue light transmittance exceeds 50%.

Description

technical field

[0001] The invention belongs to the technical field of light-absorbing materials, and in particular relates to an optical material with specific absorption for different wavelengths in the 280-450nm spectral region and a preparation method thereof. Background technique

[0002] As we all know, ultraviolet rays can damage human eyes. In addition, 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 invisible threat of blue light to h...
