Method for detecting lipophobicity of pollution-resistant electrophoretic coating film

The invention provides a method for detecting the lipophobicity of a pollution-resistant electrophoretic coating. The method comprises the following detection steps: (1) obliquely placing a sample plate; (2) dropping edible oil on the surface of the sample plate, and enabling the edible oil drops to drop naturally; (3) testing the time from dripping of the edible oil drops until the oil film is broken; (4) cleaning the surface of the tested sample plate; (5) wiping the surface of the cleaned sample plate to remove moisture, and airing; (6) dripping the edible oil on the aired surface again, and testing the oil film line breaking time again; (7) repeating the step (2) to the step (6), and recording the time of oil film line breakage each time; and (8) determining the oleophobicity of the electrophoretic coating film based on the recorded time of line breakage of the oil film. The detection method provided by the invention has a standard operation process and an operation specification, and can simulate the ole
