Abstract

The invention provides an OCA optical cement for a mobile phone glass screen protector. The OCA optical cement is prepared by reaction between the following substances by mass percent: 50-90% of aliphatic polyurethane acrylate, 1-20% of isobornyl methacrylate, 1-20% of 2-ethylhexyl acrylate, 1-20% of hydroxypropyl methacrylate and 0.1-10% of an initiator. The components are sequentially added into a stirred tank by mass percent, uniform mixing and stirring are performed under a dark condition, the mixture is naturally left to stand for defoaming to prepare a glue, after that, a PET release film is coated with the glue by use of a scraper or a coater, and UV curing is performed after attachment of the PET release film. The OCA optical cement has the beneficial effects that the light transmittance is high, the adhesive property, the water resistance and the anti-aging performance are excellent, the stripping performance is favorable, coating production is easy, the 100% curing environmental protection effect is good and the price is low.

Description

technical field [0001] The invention relates to an OCA optical adhesive, in particular to an OCA optical adhesive for a mobile phone glass screen protective film. Background technique [0002] The rapid development of mobile phone products has led to the rapid rise of related industries, and mobile phone protective film is one of them. During use, the mobile phone screen will be damaged or even broken by various internal or external stresses. Therefore, it is the most common protection method to stick a protective film on the outer layer of the mobile phone screen. Among some similar domestic products, some physical properties such as glue viscosity and hardness cannot be accepted by the required enterprises, and the small molecular substances in the film of some products will migrate to the substrate to be bonded with the bonding time. Importing from abroad is expensive. . Contents of the invention [0003] In order to solve the above-mentioned problems, the present in...
