Abstract

The invention relates to a glue, concretely relates to a transparent OCA optical adhesive for mobile phone screens, and belongs to the technical field of acrylate pressure-sensitive adhesives. The transparent OCA optical adhesive for mobile phone screens includes, by weight, 30-80 parts of hydroxypropyl methacrylate, 40-50 parts of glycidyl methacrylate, 6-20 parts of isooctyl acrylate, 2-6 partsof benzene polycarboxylate, 1-4 parts of hydroxybenzophenone, 1-5 parts of phthalate, 1-3 parts of 2-hydroxy-2-methyl-1-methyl-phenyl-1-acetone, 2-4 parts of tert-dodecylmercaptan, 1-5 parts of hydroquinone and 1-2 parts of benzoyl peroxide. Raw materials are compounded in the invention, so the light transmittance of the OCA optical adhesive reaches 98% or more, the visual effect of the screens isenhanced, and the display brightness, the display sharpness and the visual angle of the screens are greatly improved.

Description

technical field [0001] The invention relates to a rubber material, in particular to a transparent OCA optical glue 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. But the light transmittance of the existing OCA optical glue is not ideal. Contents of the invention [0003] The purpose of the...
