Abstract

The invention relates to a super-wear-resistant and super-amphiphobic coating as well as a preparation method and application thereof, belonging to the technical field of coating preparation. The preparation process comprises the following steps: mixing resin powder, hydrophobic powder and an auxiliary agent, then putting the obtained mixture into a twin-screw mixer for melting and extruding, and then tabletting and crushing; grinding the crushed the sheets, and sieving to obtain a powder coating; dispersing aqueous silica sol into an aqueous solution, adding ammonia water for carrying out alkalization treatment, then adding the solution into an ethanol solution, mixing uniformly and then adding a hydrophobic modifier, stirring and standing to obtain a nano-super-amphiphobic coating; electrostatically spraying the powder coating to obtain a primer coating, and then spraying the nano-super-amphiphobic coating onto the surface of the primer coating to obtain the super-wear-resistant and super-amphiphobic coating. According to the preparation method provided by the invention, a large roughness surface structure is prepared by means of an electrostatic powder spraying process; due to the introduction of the functional finish coating, the super-amphiphobic coating with ultra-high wear resistance and anti-icing performance can be obtained; the super-wear-resistant and super-amphiphobic coating can be applied to preparation of kitchen utensils and equipment, inner walls of refrigeration equipment or outer walls of outdoor facilities in cold areas.

Description

technical field

[0001] The invention belongs to the technical field of coating preparation, and in particular relates to a super-wear-resistant super-amphiphobic coating and a preparation method and application thereof. Background technique

[0002] Based on the concept of bionics, people first observed the special micro-nano composite structure on the surface of the lotus leaf, thus proposed the concept of superhydrophobic, and developed a superhydrophobic surface coating; further, through its The surface energy is further reduced, which can make it superoleophobic. Through a large number of studies, it has been found that superhydrophobic surfaces in nature often have rough nanostructures and low surface energy substances, so constructing rough surfaces on low surface energy substances and modifying low surface energy substances on rough surface structures can be prepared. Superhydrophobic surface biomimetic coating. However, among the superhydrophobic coatings prepared ...
