Embodiment 1
[0037] A preparation method of an environment-friendly antirust powder coating,
[0038] a. Select a reaction kettle with a large enough volume, and install a stirrer, a constant temperature heater, a reflux condenser, a thermometer, an air inlet pipe, and a decompression device on the reaction kettle for backup;
[0039] b. Add 200 parts of toluene solution to the reaction kettle prepared in a, turn on the constant temperature heater to heat the toluene solution at a constant temperature, and feed nitrogen into the inlet pipe for 25 minutes to get rid of the air in the reaction kettle;
[0040] c, adjust the constant temperature heater to ensure that the temperature in the reactor after step b is at 70°C, slowly add 55 parts of GMA type acrylic resin, 45 parts of epoxy resin, 18 parts of absolute ethanol, and 28 parts of flax in the reactor. Oil, 5 parts of titanium dioxide, 3 parts of degassing agent, 2 parts of flexibilizer, 1 part of leveling agent, and fully stirred, keep...
