▎ 摘  要

NOVELTY - Wear-resistant and waterproof film comprises sticking film composed of polyethylene film immersed in a super-hydrophobic solution. The required materials for the polyethylene film include, 60-80 pts. wt. high-density polyethylene, 5-8 pts. wt. cross-linking agent, 5-15 pts. wt. polytetrafluoroethylene, 1-3 pts. wt. antioxidant, and 15-20 pts. wt. adhesive. The materials required for the superhydrophobic solution include, 20-40 pts. wt. modified graphene, 40-60 pts. wt. deionized water, and 5-10 pts. wt. polyvinyl alcohol. USE - The wear-resistant and waterproof film is useful for household appliance. ADVANTAGE - The wearable waterproof adhesive film: has excellent water resistance, wear resistance, heat resistance, antibacterial property and mechanical strength, and prevents moisture content from falling off the film; adopts polyethylene with good barrier property as main body, and can isolate the inlet of oxygen, and improves the water resistance of the adhesive film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing wear-resistant and waterproof film comprising (1) mixing the high density polyethylene, crosslinking agent, polytetrafluoroethylene, antioxidant, adhesive uniformly, extruding to obtain polyethylene film, (2) dissolving the modified graphene in the deionized water, mixing with polyvinyl alcohol uniformly, namely super-hydrophobic solution, (3) taking the polyethylene film, soaking in the superhydrophobic solution for 4-6 hours, allowing to stand and drying to obtain the wearable waterproof film.
