Problems solved by technology

[0004] The research directions of the explosion-proof membrane glue in the prior art mostly are directions such as transparency, anti-yellowing performance under high temperature, yet the explosion-proof membrane glue also has the following problems: one, the explosion-proof membrane glue has high initial tack and high stickiness, like this It will cause that once the film is not pasted well in the actual film operation, it will be difficult to rework again; 2. The explosion-proof film glue has low initial viscosity and low stickiness, and the phenomenon of sticking will not be firm; therefore, it is urgent to develop a kind of anti-explosion film. OCA Optical Adhesive with Low Initial Viscosity and High Viscosity

Abstract

The invention relates to the field of adhesives, and specifically discloses an OCA optical adhesive, its preparation method and application, and an optical film based thereon, wherein the OCA optical adhesive includes the following components by weight: 80-120 parts of acrylic resin; 2~15 parts of isobornyl methacrylate; 0.05~1 part of tackifying resin; 0.3~1.5 parts of first photoinitiator; 0.05~0.5 part of second photoinitiator; the acrylic resin is polymerized by several kinds of acrylic monomers The acrylic monomers include: lauryl acrylate and acryloyl morpholine. Compared with the prior art, the beneficial effects of the present invention are: the acrylic resin is prepared by photoinitiated polymerization, the reaction rate is fast, the efficiency is high, the influence of temperature is small, and the reaction rate is controllable; the prepared anti-explosion membrane is used OCA optical glue is cured by ultraviolet light to form a film, which can be cured into a film in just a few seconds, with fast curing speed and high efficiency; the explosion-proof film made of OCA optical glue has the characteristics of low initial viscosity and high stickiness, and is explosion-proof The film has high transparency and low haze.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an OCA optical adhesive, a preparation method and application thereof, and an optical film based thereon. Background technique [0002] With the development of electronics and communication industries, various mobile phones, computers, and game consoles have become an indispensable part of people's lives. However, the vast majority of mobile phones, computers, game consoles, etc. on the market use liquid crystal materials as display panels. With the prolongation of use time, the liquid crystal panels are easy to become old and dirty, which affects the service life of the liquid crystal panels. In addition, the screens of electronic products are generally made of glass, which is easily broken and splashed when impacted by the outside world, posing a great safety hazard to the human body, and the low adhesion of ordinary protective films cannot play the role of explosion-proof and splash-p...
