NOVELTY - Wear-resistant polyimide film comprises 5-15 parts mass molybdenum disulfide, 9-23 parts mass thickening ingredients, 3-6 parts mass graphene, 20-25 parts mass acetamide, 5-14 parts mass pyromellitic dianhydride, 6.1-11.2 parts mass elastic ingredients, 5-10 parts mass thickening ingredients, and 3-4 parts mass polyamide. USE - Polyimide film. ADVANTAGE - The film repeatedly wraps the object to be wrapped, and has high adhesion between the two layers of polyimide film, and prevents other substances from entering the object to be wrapped. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the film, involving (a) weighing the above-mentioned components, (b) sieving the weighed clay, (c) preheating, and heat-preserving the pre-prepared reactor, (d) adding the weighed styrene, butadiene, styrene isoprene, graphene, boron oxide, silicon carbide, molybdenum disulfide and sieved clay to the above-mentioned preheated reactor in turn, and stirring, (e) continuously passing the protective gas into the reactor after the above-mentioned stirring is completed, and continuously stirring, (f) adding weighed N-methylpyrrolidone, acetamide, polyamide, ethylene, propylene and non-conjugated diene to the reactor filled with protective gas, and stirring, (g) continuously passing nitrogen gas into the reactor, and continuously stirring to obtain a mixed liquid, (h) uniformly coating the mixed liquid on a substrate, and drying the coated substrate using a drying box to obtain a dried product, and (i) cooling the dried product to room temperature to obtain the film.
