Preparation method of anti-corrosion full-automatic liquid packaging machine

The invention discloses a preparation method of an anti-corrosion full-automatic liquid packaging machine. The outer surface of the packaging machine is coated with a corrosion-resistant coating layer. The corrosion-resistant coating layer contains the following components: a metal raw material, an ethanol water solution, thermosetting resin, a corrosion-resistant aid and a direr. The preparationmethod specifically comprises the following steps: (1) preparing metal particles; (2) preparing a solvent; (3) mixing the metal particles obtained in the step (1) with the solvent obtained in the step(2), carrying out ultrasonic high-speed dispersion, and uniformly mixing, so as to obtain a corrosion-resistant coating layer product; and (4) spraying the corrosion-resistant coating layer product to the outer surface of the packaging machine, heating to 450-470 DEG C, maintaining the temperature for 1-2 hours, cooling to 220-250 DEG C, maintaining the temperature for 1-2 hours, and cooling in air to the room temperature
