NOVELTY - A graphene floating component comprises 100 pts. wt. plastic substrate, 0.1-10 pts. wt. graphene, 0.1-1 pt. wt. light stabilizer, 0.1-1 pt. wt. antioxidant and 1-15 pts. wt. color masterbatch. USE - The graphene floating component is useful for water floating system (claimed). ADVANTAGE - The graphene floating component has excellent flame retardance, antistatic performance, anti-aging performance, antibacterial property, adsorption property, strength and toughness. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing the graphene floating component, which involves evenly mixing plastic substrate, graphene, light stabilizer, antioxidant and color masterbatch according to the portion, adding the mixed materials to a twin-screw extruder, melt-extruding, granulating and screening, where the raw materials for preparing the floating component are formed into the floating component through a blow molding method, an extruder extrusion molding method, an injection molding method or a rotational molding method; and (2) use of the graphene floating component for water floating system.
