Abstract

The invention relates to an adhesive material, in particular to a blue-light-preventing OCA optical adhesive for a mobile phone screen, and belongs to the technical field of acrylate pressure-sensitive adhesives. The blue-light-preventing OCA optical adhesive comprises, by weight, 60-80 parts of lauryl methacrylate, 20-30 parts of 2-ethylhexyl acrylate, 1-6 parts of lithium diisopropylamide, 1-2 parts of bis(2,3-epoxycyclopentyl)ether, 2-4 parts of benzoin methyl ether, 2-5 parts of 2-ethylhexyl-4-dimethyl benzoate, 2-6 parts of alkyl sulfonate, 3-10 parts of polyurethane, 1-4 parts of phosphate and 1-2 parts of 2,2'-Azobis(2-methylpropionitrile). The blue-light-preventing OCA optical adhesive has excellent blue-light neutralizing and filtering effect by the aid of raw material compounding, the weather resistance of the blue-light-preventing OCA optical adhesive is increased, and the blue-light-preventing OCA optical adhesive does not fade after long-term use and is durable.

Description

technical field [0001] The invention relates to an adhesive, in particular to an anti-blue light OCA optical adhesive for mobile phone screens, and belongs to the technical field of acrylic pressure-sensitive adhesives. Background technique [0002] In recent years, the development of touch screens is extremely rapid. With the increasing number of multimedia information inquiries, people are using more and more touch screens. Optical OCA is colorless and transparent, has a light transmittance above 90%, and has good bonding strength. It can be cured at room temperature or medium temperature, and has the advantages of small curing shrinkage and no yellowing, especially for ITO glass and optical components. Non-corrosive and other advantages, so with its excellent physical and chemical properties, it is most widely used in the touch screen industry. However, the existing OCA optical glue has poor blue light neutralization and filtering effects, and the use of mobile phones fo...
