Method for preparing green nano cutting fluid through cycloid type ultrasonic stirring together with alternating electric field

The invention discloses a method for preparing a green nano cutting fluid through cycloid type ultrasonic stirring together with an alternating electric field. A conventional aggregation phenomenon ofa solution after ultrasonic stirring is not completely solved. By adopting the method, coactions of cycloid type stirring of an ultrasonic vibration stirring rod, ultrasonic pulse and alternating pulse are achieved; when a temperature sensor measures that the temperature of a former mixed liquid of a cutting fluid is greater than 60 DEG C, the ultrasonic vibration stirring rod stops vibrating, analternating electric field of two arc-shaped electrodes is kept operating, meanwhile, and a normal-temperature water flow in a water cooling channel can be increased; when the temperature sensor measures that the temperature of the former mixed liquid of the cutting fluid is reduced to a normal temperature, the ultrasonic vibration stirring rod is electrified again, and meanwhile, the flow of normal-temperature water in t
