The invention relates to a woundplast substrate and a preparation method thereof, and belongs to the technical field of medical materials. The woundplast substrate comprises the following components in parts by weight: 15-24 parts of PE (polyethylene) resin, 2-6 parts of polypropylene resin, 2-8 parts of vinyl distearamide, 2-8 parts of stearic acid, 2-5 parts of a styrene-butadiene-maleic anhydride copolymer, 1-6 parts of sodium carboxymethylcellulose, 2-8 parts of ammonium dihydrogen phosphate, 1-4 parts of polyvinylpyrrolidone and 3-10 parts of propanetriol. The woundplast substrate has good air permeability and toughness and can keep a wound fresh, cool and comfortable; the woundplast substrate has good corrosion resistance and relatively good moisture resistance; the preparation method is simple, and easy and convenient to implement, and is suitable for wide-range popularization and application. |
