Abstract

The invention provides an anti-static hardened film, which comprises a film base material and an ultraviolet-curing anti-static hardened paint layer coated on the film base material, wherein the film base material is selected from a PET (polyethylene glycol terephthalate) film, a PC (polycarbonate) film or a PMMA (polymethyl methacrylate) film; and the ultraviolet-curing anti-static hardened paint layer is prepared from the following components by weight: 20-40% of multifunctional polyurethane acrylates, 50-70% of alcohol and / or ether reagent, 5-10% of UV (ultraviolet) curing active monomer, 1-20% of organic surfactant anti-static agent, 1-10% of photoinitiator and 0.1-0.5% of paint assistant which are subjected to ultraviolet-curing. The film provided by the invention has a good anti-static effect, high transmittance, high hardness and good wear resistance, and has no whitening and fogging phenomena on the surface.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an antistatic hardening film. Background technique [0002] In modern industrial production, it is known that the method of preparing a hardened film is to coat a hardened liquid on a film substrate such as PET, PC, PMMA, and form a hardened layer after curing, so that it has a certain hardness and wear resistance, which has been widely used. Applied to the anti-scratch protection of mobile phone screen, touch display screen, LCD screen, electrical nameplate, IMD in-mold decoration, instrument panel, light guide plate, flat panel display, etc. On the other hand, while providing hardened layer protection for the above-mentioned panels, it is also hoped that the surface has an antistatic and dustproof effect. The processing process of the powder hinders the normal winding of the film or fiber, and the powder will agglomerate or bridge due to static electricity during transport...
