A mildew-proof preservative film, comprising a base layer and a mildew-proof preservative coating provided on the base layer. The mildew-proof preservative coating is made from a mildew-proof preservative paint. The paint comprises the following components in percentage by weight: 20-60% of resin, 30-70% of solvent, 0.5-10% of mildew preventive, and 0.3-5% of additive. The resin is at least one of polyurethane, an acrylate copolymer, polyvinyl alcohol, polyvinylidene chloride, modified polyvinylidene chloride, an ethylene-vinyl acetate copolymer, a polyvinyl acetate copolymer, and a vinyl acetate-butyl ester copolymer; and the solvent is at least one of water and ethanol. A preparation method for the mildew-proof preservative film comprises the following steps: uniformly mixing the resin, the solvent, and the additive to obtain a mixed liquid; uniformly mixing the mixed liquid and mildew preventive to obtain a paint; then coating the base layer with the paint, and conducting heat treatment so that the paint forms a coating, so as to obtain the mildew-proof preservative film. |
