Abstract

The invention relates to the technical field of ceramic production, in particular to a multifunctional hardening film which comprises acrylic resin hardening liquid of which a transparent polyimide base material is doped with an ionic antistatic agent. According to the invention, four functions of high wear resistance, high water drop angle, fog resistance and static resistance are integrated to realize a coating process and a hardening liquid formula at one time, special ultraviolet curing acrylic resin is adopted, and the resin contains hydrophilic groups, has good hydrophilic performance and can realize the fog resistance function; the ionic antistatic agent is also doped in the HC resin coating, so that an antistatic function can be realized, the heavy hammer resistance can be 108-1011 ohms, and the HC resin coating also has very strong friction resistance. The hardening film is realized by adopting a roller coating mode, the thickness of a dry film reaches 3-4 microns through ultraviolet curing of the UV-A waveband, the antistatic value can reach 109-1011 ohms, and the wear-resisting frequency reaches more than 2000 times.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to a multifunctional hardened film and a method thereof. Background technique [0002] As the protection requirements for electronic product panels are getting higher and higher, the requirements for hardened protective films on the surface are also getting higher and higher. It is necessary to realize that electronic products need supporting protective films in multiple directions, so it is necessary to develop a new type of hardened protective film with composite functions. [0003] At present, the basic process of ordinary hardened film is to coat a layer of ordinary acrylate hardened coating on the PET substrate, and then form a layer of hardened coating after UV curing. Generally, this coating cannot achieve high wear resistance. , antistatic, high water drop angle, anti-fog functions in one. Contents of the invention [0004] The purpose of the present invent...
