| titleOfInvention | Protective film and preparation method thereof |
| abstract | The invention relates to the field of protective film materials, in particular to a protective film and a preparation method thereof. The invention provides a protective film and a preparation method thereof, aiming at solving the problem that a large amount of static electricity is easily generated between an adhesive layer of the protective film and the surface of an optical film in the process of tearing the conventional protective film from the optical film. The protective film sequentially comprises a surface layer, a core layer and an adhesive layer from top to bottom; the surface layer comprises 97-99.5% of polypropylene resin and 0.5-3% of an opening agent; the core layer comprises 100% of polypropylene resin; the adhesive layer comprises 60-82% of styrene thermoplastic elastomer, 15-39% of polyolefin resin and 1-3% of antistatic agent; the antistatic agent is selected from a mixture of polyether ester amide and glyceride; the percentage is weight percentage. The protective film provided by the invention has small instant tearing and protecting static electricity, high static dissipation speed after tearing and protecting, does not have the problem of precipitation, and is suitable for optical protective films with low static electricity requirements. |
