▎ 摘  要

NOVELTY - Production of metal-nanowire-containing aqueous toughened coating involves adding metal oxide nanowires to a pre-treated graphene dispersion, fully dispersing by ultrasonic treatment, vacuum filtering, heating the product in a quartz tube furnace to 300-330 degrees C under nitrogen atmosphere, maintaining warm for 2-3 hours, cooling to room temperature, grinding to obtain graphene/nanowire composite powder, heating and melting the graphene/nanowire composite powder with polyethylene glycol in a vacuum adsorption device while maintaining the relative vacuum degree in the cavity at -40 kPa to -30 kPa, mixing for 15-20 minutes under ultrasonic oscillation, cooling, pulverizing and grinding to obtain composite particles, adding a white aqueous coating, filler, an additive, and deionized water to a mixer at a rotation speed of 1000-1300 rpm, stirring at 55-65 degrees C for 3-4 hours to obtain a mixture, adding the composite particles and metal oxide nanowires, and continually stirring for 1-2 hours. USE - Production of metal-nanowire-containing aqueous toughened coating used for elastic plastic. ADVANTAGE - The method produces metal-nanowire-containing aqueous toughened coating having excellent flexibility and impact strength.
