Water-based fluorine coating for roller spraying and preparation method of water-based fluorine coating

The invention relates to the field of coatings, and discloses a water-based fluorine coating for roller spraying and a preparation method of the water-based fluorine coating. The coating is prepared from the following components in parts by weight: 100 parts of organic silicon modified fat polyurethane emulsion, 10 to 35 parts of thermosetting water-based acrylic resin, 10 to 20 parts of methylated amino resin, 10 to 30 parts of polytetrafluoroethylene emulsion, 10 to 30 parts of PTFE micro powder, 1 to 40 parts of surfactant, 10 to 40 parts of ethanol, 1 to 5 parts of sodium formate, 10 to 30 parts of ammonia water and 80 to 200 parts of water. The organic silicon modified fat polyurethane emulsion, the methylated amino resin, the polytetrafluoroethylene emulsion and the PTFE micro powder are adopted, so that the high-temperature resistance of the coating is improved, and the coating can meet the requirement that the coating is resistant to the temperature of 200 DEG C and does not fall off, crack and discol
