Problems solved by technology

After a large number of studies, it has been proved that the superhydrophobicity of the surface reduces the adhesion strength of ice on the surface
However, recent studies have shown that most of the prepared super-hydrophobic or super-amphiphobic surfaces cannot resist freezing for a long time: especially when the super-hydrophobic surface encounters extremely low ambient temperature and high humidity The situation is not ideal, and sometimes even the surface is more difficult to remove once it is frozen

Abstract

The invention relates to the field of preparation of super-hydrophobic or super-amphiphobic coatings, in particular relates to a preparation method of a sustainable anti-icing super-amphiphobic coating. The method comprises the following steps: 1, cleaning a substrate surface and carrying out sand-blasting roughening treatment; 2, blending epoxy resins, epoxy resin curing agents and a first solvent to obtain an epoxy resin solution; 3, dispersing submicron particles and nanoparticles into a second solvent, and then adding fluoroalkyl silane to obtain particle composite suspension liquid; 4, spraying substrate surface subjected to the treatment in step 1 with the epoxy resin solution obtained in step 2, and carrying out semi-curing on the epoxy resin adhesive; 5, spraying the substrate surface subjected to the treatment in step 4 with the particle composite suspension liquid obtained in step 3, and carrying out complete curing; 6, obtaining the sustainable anti-icing super-amphiphobic coating. The method has the advantages that the super-amphiphobic coating prepared on all substrate surfaces has good durability and fastness, and has sustainable anti-icing performance.

Description

technical field [0001] The invention relates to the field of preparation of super-hydrophobic or super-amphiphobic coatings, in particular to a preparation method of a durable anti-icing super-amphiphobic coating. Background technique [0002] Surface wettability is one of the important characteristics of solid surface, wettability can be measured by the contact angle of water on the surface; superhydrophobic surface because of its contact angle to water is greater than 150°, rolling angle is less than 10°, and has self- The cleaning properties have aroused great interest in both academia and industry. In nature, the leaves and petals of many plants, the wings of insects, and the feathers of birds are all natural superhydrophobic materials. The self-cleaning function of the superhydrophobic surface means that surface pollutants such as dust can be carried away by rolling water droplets without leaving any traces. Self-cleaning coating has the advantages of water saving, en...
