Problems solved by technology

[0003] When phone lovers use a protective film to attach a protective film to the screen of their favorite phone, it is easy to re-attach due to poor positioning. Improper operation will easily cause stains on the rubber surface of the protective film, which will affect the positioning effect of the protective film and affect the screen. beautiful
[0004] In addition, in order to improve the wear resistance and impact strength of the protective film, a layer of hardened layer is often coated in the protective film to improve the hardness of the protective film. However, the hardened coating of the existing optical protective film is often a single photocurable material , the color is not uniform on the display screen, and there is a significant phenomenon of rainbow pattern

Abstract

The invention relates to the technical field of optical protective films, and in particular relates to a hardening coating and an easily torn and located protective film prepared by utilizing the hardening coating. The hardening coating disclosed by the invention comprises the following raw materials by weight percent: 50-70% of epoxy acrylate, 5-10% of urethane acrylate, 5-10% of methyl methacrylate, 5-12% of butyl acrylate, 5-10% of hydroxyethyl acrylate, 2-5% of benzoin ethyl ether, 0.5-3% of benzophenone, 0.1-2% of triethanolamine, 0.1-2% of a polysiloxane-polyether copolymer, and 0.5-5% of EDAB. The easily torn and located protective film prepared by utilizing the hardening coating has the characteristics of uniform colour and lustre and low newton ring; furthermore, the easily torn and located protective film is simple to operate and is torn and located easily and can be well pasted in place once; and the easily torn and located protective film is easy to install, rapid to exhaust, repetitive to paste, free from residual glue and the like and can be widely applied to protecting various liquid crystal display screens.
