▎ 摘  要

NOVELTY - Preparing silane-modified graphene involves adding graphene oxide and solvent to the reactor, stirring at room temperature for 12-36 hours, subjecting to ultrasonic vibration for 30-60 minutes, adding silane coupling agent to the reactor, warming up to 50-200 degrees C, stirring and reacting for 12-36 hours, and stop the reaction when the mixed solution turns from golden brown to black brown. USE - Method for preparing silane-modified graphene. ADVANTAGE - The method enables to prepare silane-modified graphene improves anti-corrosion performance of sheet metal in heavy corrosion environment. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a sheet metal portion which comprises metal plate, where the anti-corrosion coating is provided on the metal plate and silane-modified graphene coating is sandwiched between Between the metal plate and the anti-corrosion coating; (2) an outdoor unit of an air conditioner, which comprises casing which is made of the sheet metal portion; and (3) an air conditioner, which comprises an air conditioner indoor unit and the air conditioner outdoor unit, where the air conditioner outdoor unit and the air conditioner indoor unit are connected by a refrigerant pipe.
