Embodiment 1
[0027] A kind of noise reduction graphene anticorrosion coating and preparation method for railway facilities, the concrete process of its preparation anticorrosion coating is as follows:
[0028] Heat the sodium peroxide powder to remove crystal water, and vacuum-dry the graphene powder, then mix 10kg of sodium peroxide powder and 30kg of graphene powder at high speed in a dry environment that isolates carbon dioxide and oxygen, and the mixing temperature is 40°C. The rotation speed is 100r / min, the time is 10min, and then cooled to room temperature to obtain dry mixed powder; preheat the multifunctional coating pan to 60°C, set the fan frequency to 20Hz, and the air outlet temperature to 75°C, place the mixed powder in Preheating is carried out in the coating pan, while adopting hot air to dry. Then turn on the rotating device, set the rotating frequency as 25Hz, and make the powder rotate evenly in the coating pan. Then turn on the spray pump, set the spray frequency to 4H...
