Method for testing wear resistance of super-hydrophobic coating based on abrasive paper

Abstract

The invention provides a method for testing the wear resistance of a super-hydrophobic coating based on abrasive paper. The method comprises the following steps: wearing the surface of the super-hydrophobic coating by using the abrasive paper loaded with different load; measuring the static contact angle, the slip angle, the root-mean-square roughness and the surface appearance of the surface of the super-hydrophobic coating after the super-hydrophobic coating is worn by the abrasive paper with one kind of load; comparing the static contact angle, the slip angle, the root-mean-square roughnessand the surface appearance of the surface of the super-hydrophobic coating after the super-hydrophobic coating is worn by the abrasive paper with different load, and evaluating the wear resistance ofthe super-hydrophobic coating. According to the method, provided by the invention, for testing the wear resistance of the super-hydrophobic coating based on the abrasive paper, the static contact angle, the slip angle, the root-mean-square roughness and the surface appearance of the surface of the super-hydrophobic coating after the super-hydrophobic coating is worn by the abrasive paper with different load are compared, the wear resistance of the super-hydrophobic coating is judged, the wear resistance test of the super-hydrophobic coating can be conducted conveniently and accurately, and the method is simple to operate and low in cost.

Description

technical field [0001] The invention relates to the technical field of testing superhydrophobic coatings, in particular to a method for testing abrasion resistance of superhydrophobic coatings based on sandpaper. Background technique [0002] Superhydrophobic material is a low surface energy material with a static contact angle of more than 150° and a rolling angle of less than 10°. It has broad application prospects and is currently widely used as a superhydrophobic coating. Superhydrophobic coatings are both superhydrophobic and transparent, and have major functional requirements in difficult engineering technologies such as self-cleaning of solar panels, antifouling of touch screens, and anti-icing of windshields, thus promoting the large-scale production of high-quality superhydrophobic materials. , Batch preparation technology research and development. [0003] In the natural environment and during transportation and construction, the surface of the superhydrophobic c...
