Problems solved by technology

When electronic products are in use, the light emitted by the LED lights contains blue light that is very harmful to the human body. Blue light refers to high-energy light with a wavelength of 380nm to 480nm, which can penetrate the lens to reach the retina, making the retinal pigment epithelium Cell death causes light-sensitive cells to lack nutrients, which causes irreversible vision damage, and blue light has a high probability of scattering when encountering fine particles in the air, which is prone to glare and causes great damage to human eyes

Abstract

The invention discloses an anti-blue-ray optical clear adhesive (OCA). The optical clear adhesive comprises the following components in parts by weight: 100 parts of an acrylate adhesive, 0.1-2 partsof a crosslinking agent, 0.05-2 parts of a silane coupling agent, 0.01-0.5 part of an antioxidant and 0.05-0.5 part of an anti-blue-ray additive, wherein the weight-average molecular weight of the acrylate adhesive is in a range of 1 million to 2 million, and the glass transition temperature of the acrylate adhesive is -60 DEG C to -30 DEG C; the antioxidant is selected from at least one of a p-phenylene diamine antioxidant and a phosphite antioxidant; and the anti-blue-ray additive is selected from at least one of a ketone anti-blue-ray additive and a tungstate anti-blue-ray additive. The optical clear adhesive has a good bonding performance and also has an anti-blue-ray effect, the filtering rate of the optical clear adhesive on the blue light wave band of 370 nm to 450 nm reaches 95% orabove, and the eyes can be well protected.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an anti-blue light OCA optical adhesive. Background technique [0002] In recent years, with the development of society, the use of electronic products has become more and more popular. People are almost inseparable from the use of electronic products such as computers and mobile phones in their daily work and life. Optical adhesive (OCA) plays an important role in the displays of various electronic products. When electronic products are in use, the light emitted by the LED lights contains blue light that is very harmful to the human body. Blue light refers to high-energy light with a wavelength of 380nm to 480nm, which can penetrate the lens to reach the retina, making the retinal pigment epithelium Cell death causes light-sensitive cells to lack nutrients, causing irreversible vision damage, and blue light has a high probability of scattering when it encounters fine ...
