Fluorine electronic protective coating and preparation method thereof

The invention belongs to the technical field of fluorine-containing protective materials, and particularly relates to a fluorine-containing electronic protective coating and a preparation method thereof. The fluorine-containing electronic protective coating is prepared from the following components in percentage by mass: 1 to 50 percent of fluorine-containing acrylic resin and 50 to 99 percent of organic solvent, the fluorine-containing acrylic resin comprises the following components in percentage by mole: 5-45% of fluorine-containing acrylate unit; 50-90% of a non-fluorinated acrylate unit; and 0.1-5% of a functional acrylate unit. The fluorine-containing electronic protective coating provided by the invention has excellent hydrophobicity, the functional monomer provides active groups such as carboxyl and hydroxyl for the resin, the functional monomer can be chemically bonded with a base material, and good adhesive force and durability are provided for a coating after film formation. The molecular weight is
