Abstract

The invention discloses an electric performance sample preparation and detection method of a super hydrophobic coating. By using a dip-coating method, the super hydrophobic coating is prepared on a red copper sheet substrate to detect volume resistivity, relative dielectric constant, dielectric loss tangent value and breakdown strength of the super hydrophobic coating; and by using a spray method,the super hydrophobic coating is sprayed to a glass plate so as to carry out tracking and erosion resistance and electric erosion resistance tests of the coating. The electric performance sample preparation and detection method of the super hydrophobic coating comprises the following steps: (1) perforating a red copper sheet; (2) washing the red copper sheet; (3) preparing a red copper sheet coating; (4) perforating and washing the glass plate; (5) preparing a glass sheet coating; and (6) detecting electric performance. The electric performance sample preparation and detection method of the super hydrophobic coating, disclosed by the invention, has the advantages that a super hydrophobic coating electric performance detection sample preparation idea is provided, technical problems of non-uniform sample coating, packaging air bubbles and the like are solved, electric insulation performance parameters of the super hydrophobic coating can be detected, and the application of the super hydrophobic coating in the electric insulation field is opened.

Description

Technical field [0001] The invention relates to the technical field of superhydrophobic coating performance detection, in particular to a sample preparation and detection method for electrical properties of a superhydrophobic coating. Background technique [0002] At present, due to the serious pollution of the surface of the transmission line insulators, pollution flashover accidents occur from time to time. Applying an anti-pollution flashover coating on the surface of the insulator is a method that can effectively increase the pollution flashover voltage and reduce pollution flashover accidents. Existing anti-pollution flashover coatings have insufficient hydrophobicity, and the water contact angle is basically maintained at about 120°, and water droplets drop on the anti-pollution flashover coating, which has strong viscosity and is not easy to roll. The coating cannot meet the increasing external insulation level of transmission lines. [0003] Super-hydrophobic coating refer...
