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, in particular to an antistatic hardening film. Background technique [0002] In modern industrial production, the known method for preparing hardened film is to coat hardening liquid on film substrates such as PET, PC, PMMA, etc., and then solidify to form a hardened layer, so that it has certain hardness and wear resistance, which has been widely used. It is used for anti-scratch protection on mobile phone screens, touch screens, liquid crystal screens, electrical nameplates, IMD in-mold decoration, instrument panels, light guide plates, flat panel displays, etc. On the other hand, while providing hardened layer protection for the above-mentioned panels, it is also hoped that the surface has an anti-static and dust-proof effect. The hazards caused by static electricity are mainly: (1) Seriously interfere with plastic products with large surface areas such as films, fibers or The powder processing proce...
