Problems solved by technology

However, the existing superhydrophobic and oleophobic coating preparation methods have the following shortcomings: special equipment (plasma, laser etching), not conducive to large-scale construction, special requirements for substrates, only suitable for specific surfaces, and general molding The process is complicated and the cost is high, which severely limits the wide application of this type of material
[0003] In the article "Preparation and Research of Superhydrophobic / Oleophobic Coating", Xu Runbin prepared nano-alumina particles by conventional grinding method, and prepared nano-silica particles by sol-gel method. The surface grafting treatment of the two was carried out by the joint agent respectively, and the surface fluorine-modified nanoparticles and microparticles were obtained as pigments and fillers. Secondly, a fluorine-containing hydroxyl acrylic resin was prepared by using various types of acrylic monomers as the main resin of the adhesive. 1. Select perfluoroalkyl alcohol and hexamethylene diisocyanate trimer to prepare a fluorine-containing isocyanate curing agent. As a result, the acrylic polyurethane varnish film prepared by mixing paint on the surface has good performance, adhesion level 1, flexibility 1mm , impact 50cm, hardness 2H, the static contact angle for water can reach up to 104°, finally disperse the prepared nano and micro particles in fluorine-containing hydroxyl acrylic resin, adjust the pigment-base ratio and the ratio of nano / micro particles, and A variety of superhydrophobic-oleophobic coatings are prepared with dispersants, anti-sedimentation additives and curing agents. The test results show that the coatings have good adhesion, flexibility and film strength. At this time, the coating film is resistant to water and vegetables. The static contact angles of seed oil and aviation hydraulic oil are 154°, 100° and 94° respectively, indicating that the coating has a good separation effect on water and oil. Oil has a certain effect, but the contact angle to oil has not reached more than 150°, and the strength, wear resistance, durability, stability and mechanical properties of the coating are average, which cannot meet the actual use requirements and limit the super double Industrial application of hydrophobic coating

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a modified artificial diamond superamphiphobic wear-resistant imitation ceramic coating. Background technique [0002] Wettability is an important property of solid surfaces, and it is generally believed that the microstructure and chemical composition of a solid surface play a key role in the wettability it exhibits. The wettability of solid surfaces plays an important role in daily life and industrial and agricultural production, such as washing, printing and dyeing, dispersion of paint, use of lubricating oil, penetration of skin care products, etc. At present, people call this phenomenon that water does not stick to water and water droplets can roll off by themselves as super-hydrophobic phenomenon, and the surface with this property is called super-hydrophobic surface. Researchers have done more research on super-hydrophobic coatings, but this type The coating is often sta...
