Abstract

The invention relates to a blue light-blocking acrylic adhesive, which is characterized in that a certain amount of a filtering blue light dye is added in an acrylic adhesive to filter blue light having a certain wavelength, wherein the acrylic adhesive is one or more of a water solvable pressure-sensitive adhesive, an emulsion type pressure sensitive adhesive, a solvent pressure sensitive adhesive and a non-solvent pressure sensitive adhesive. The blue light-blocking acrylic adhesive and the film prepared from the blue light-blocking acrylic adhesive have the following beneficial effects that 1) structure is simple, and production is easy; and 2) high-energy shortwave blue-light can be effectively blocked. By changing the optical characteristics of the acrylic adhesive, the characteristics of the acrylic adhesive can be kept, and effective blocking of high-strength blue light which is harm to eyes can be realized. The film can be used for bonding module components of a liquid crystal display, and also can be used for producing various protection films, explosion-proof membranes, non-substrate optical cement (OCA), liquid crystal displays, and products relative to LED light sources.

Description

technical field [0001] The invention relates to a material for blocking blue light, in particular to a blue light blocking acrylic glue and a film made thereof. Background technique [0002] The high-energy short-wave blue light emitted by the display or light source during use is very harmful to human eyes. Short-wave blue light refers to light with a wavelength between 380 and 500 nanometers in visible light. Short-wave blue light has extremely high energy and can penetrate the lens directly to the retina. Blue light irradiating the retina will produce free radicals, and these free radicals will lead to the death of retinal pigment epithelial cells. The death of epithelial cells will lead to the lack of nutrients for light-sensitive cells and cause vision damage, and these damages are irreversible. If the irradiation time exceeds 10 seconds, this damage mechanism plays a major role and is several times that of thermal damage. Blue light is the leading cause of digital e...
