Embodiment Construction

[0022] The specific implementation of the present invention will be described in further detail below through the description of the embodiments, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and to help them implement.

[0023] Reference attached figure 1 , the superhydrophobic coating wear-resistant test method based on sandpaper provided by the invention comprises the following steps:

[0024] S101: Abrading the surface of the super-hydrophobic coating with sandpaper loaded with different loads.

[0025] Use sandpaper with different loads to wear the surface of the super-hydrophobic coating. Usually, the sandpaper used is not less than 1000 mesh. It helps to improve the accuracy of testing the wear resistance of superhydrophobic coatings. In the specific embodiment of the present invention, 1500 mesh is preferred, but it is not limited to 1500 m...

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...
