Anti-blue ray resin composition and preparation method thereof

Abstract

The invention relates to an anti-blue ray resin composition and a preparation method thereof. The resin composition contains the following components: resin, an ultraviolet absorbent, a free radical capturing agent, an antioxidant and azo pigments. The preparation method comprises uniformly mixing the resin, the ultraviolet absorbent, the free radical capturing agent, the azo pigments, the antioxidant, a solvent and a curing agent in percentage by weight so as to obtain a mixture, coating base materials such as glass, PET, PVC and PP with the mixture, heating, and drying, so as to obtain an anti-blue ray coating layer. The ray resin composition is capable of further absorbing 380nm-425nm high energy waves harmful to human eyes. By forming a film through the coating of the resin composition, the problem that the heat resistance of materials is poor can be avoided. A production process is simple, the materials are wide in sources and cheap, and the process can meet the market demands andblue ray protection requirements of customers. The equipment investment is low, so that the industrial production is easily realized. The prepared film can be applied to the adhesion of each module of a liquid crystal display and can be applied to the production of products of various types of protection films, LED display screens, LED light sources and the like.

Description

technical field [0001] The invention relates to an anti-blue light resin composition and a preparation method thereof. The composition can further absorb high-energy wavelengths of 380-425nm that are harmful to human eyes, and has high transmittance to light of other wavelengths that are harmless, so as to reduce product Hue changes, maintaining high brightness of the display. Background technique [0002] With the improvement of living standards, LED displays or light sources will be used in daily life. The LED is excited to emit blue light, and then the blue light excites the phosphor to emit yellow light, and the blue and yellow light are mixed to obtain white light. Limited by the excitation efficiency of phosphor powder, in the blue light band, the relatively high-energy part, such as the high-energy short-wavelength light of 380-500nm, will remain. For example, the currently popular LED screens of mobile phones will directly irradiate human eyes with a large amount o...
