The invention relates to the field of protective films, in particular to a protective film and a preparation method thereof. The protective film comprises a base material film layer and an adhesive layer from top to bottom in sequence; the base material film layer sequentially comprises a first corona layer, a bright layer, an antistatic layer, an inner layer, an anti-oxidation layer, a matte layer and a second corona layer; the inner layer is prepared from the following raw materials in parts by weight: 70-80 parts of polyolefin, 60-70 parts of elastomer, 10-15 parts of cross-linking agent and 2-5 parts of color master batch; the adhesive layer is prepared from the following raw materials in parts by weight: 50-100 parts of reactive monomer, 60-80 parts of diluent, 0-10 parts of curing agent and 0-10 parts of stabilizer. The protective film provided by the invention has excellent barrier property, curing formability, light transmittance, expansibility, mechanical property, water resistance, temperature resistance and aging resistance, is environment-friendly, and has no adhesive residue after being stripped. |
