The invention provides a silicone rubber hydrophobic property discrimination method based on an initial hydrophobic angle and surface energy test. The method comprises the following steps: firstly testing a static hydrophobic angle of a sample by using deionized water, and classifying the hydrophobic property of the sample according to a test value: when the sample has the hydrophobic property, further determining the better hydrophobic property or excellent hydrophobic property of the sample; when the sample has the excellent hydrophobic property, performing the supplementary test: replacinga test solution with glycerol, testing the static hydrophobic angle of the sample, and recording the test data; and finally, for the sample with better hydrophobic property and excellent hydrophobic property, continuing the test of the static hydrophobic angle of the sample under the ethylene glycol condition, and recording the test data. An OWRK method is used for performing the surface energy calculation to obtain the surface energy of the sample. By adopting the method, the nonlinear change situation of the hydrophobic angle and hydrophobic property when the hydrophobic angle is large can be solved, and the sample can be more intuitively judged. The test accuracy can be improved. The problem that the ultra-hydrophobic material cannot be tested by using the traditional hydrophobic angletest method can be solved.
