The invention relates to the field of coating easy to clean and discloses a preparing method of core-shell structure coating easy to clean. The preparing method is characterized by comprising the steps that firstly, nano particles and alcohol solvent are mixed evenly under stirring, a coupling agent is added under stirring, and an alcoholic solution of a nano particle microballoon sphere structure is obtained; secondly, organic solvent is added to the alcoholic solution of the nano particle microballoon sphere structure, an initiator is added for the first time under stirring at the inert atmosphere and at the temperature from 15 DEG C to 50 DEG C, the temperature is increased to 60 DEG C to 105 DEG C, silicon-containing monomers, fluorine-containing monomers, ester monomers and a dispersing agent are added, the initiator is added for the second time, a reaction is conducted, and the mixture is cooled to the indoor temperature after reaction is completed. The invention further discloses the core-shell structure coating easy to clean and application of the coating in kitchen appliances, and the coating is prepared through the method. The coating is easy to clean, resistant to acid and alkali and resistant to scraping, and can be widely applied to the kitchen appliances.

The invention provides a color-developing paint used for inspecting fuel spillage of an aircraft during flight, which belongs to the paint collar. The color-developing coating provided by the present invention for inspecting fuel spillage of an aircraft during flight comprises 30-50 parts of oil-soluble resin, 30-50 parts of solvent, 0.5-2 parts of fluorescent color developer, 5-5 parts by weight 18 parts of toughening agent, 0.1-0.5 parts of coating additives. The coating film formed by this coating can withstand the maximum air velocity of 0.85Ma during the flight test of the aircraft without falling off; the drying time at 25°C is controlled to about 2‑3 hours; it does not crack or fall off at ‑60°C; the coating film can Smooth and flat; excellent performance, water resistance, heat and humidity resistance, high and low temperature cycle resistance; excellent color rendering, the color will be dissolved immediately when the fuel drips, and the color development traces will remain; the coating is easy to remove, and the aviation fuel can be easily removed after the aircraft test flight Wipe off; no harm to aircraft skin after removal.

The invention discloses a method for preparing a light-shielding tape for a wireless charger, comprising a black ink layer, a substrate layer and an adhesive layer, wherein the black ink layer and the adhesive layer are respectively located on the upper surface of the substrate layer and the lower surface, the side of the adhesive layer opposite to the base material layer is provided with a release layer; the black ink layer is obtained by drying the black ink, and the black ink is prepared by the following steps: S1. 60~80 parts of water-based polyurethane, 15~25 parts of deionized water, 1~5 parts of 1,1',1"-methylenetris(4-isocyanato)benzene, 0.01~0.03 parts of sodium tripolyphosphate added at high speed Stir in the dispersing agent, the speed is 300~500r / min, and the mixing is uniform; S2, add 1~5 parts of carbon black, 1~1.5 parts of sodium silicate, 1~5 parts of polyethyleneimine, 0.5~2 parts of eighteen Alkyl dimethyl benzyl ammonium chloride and 0.5~1.5 parts of coupling agent, the rotating speed is adjusted to 500~600r / min, and the dispersion and stirring are uniform. The invention has anti-fingerprint performance, and will not remain after repeated use in various environments Fingerprint marks can avoid the corrosion of the tape caused by fingerprints and sweat stains.

The UV-cured high stain-resistant and wear-resistant dull floor paint of the present invention comprises: modified polyurethane acrylate resins I and II; active monomers with three, four, and six functional groups; leveling agents I and II; defoaming agents Dispersant; Initiator; Matting powder I and II; Nano-silicon carbide powder; Nano-silicon nitride powder; The glossiness of the present invention is below 3 degrees, which belongs to the matt coating, and the wear index is within 6mg, which can easily wipe off the pollution on the paint film, the common colors or marks in life without leaving traces, and has high durability Good performance of anti-pollution and high wear resistance; no organic solvent, environmentally friendly and healthy, and can meet customers' needs for personalized high-end floor coatings.

The invention relates to the field of easy-to-clean coatings, and discloses a preparation method of an amphiphobic, antibacterial and easy-to-clean coating. The method comprises steps as follows: (1) placing chitosan in a glacial acetic acid aqueous solution for ultrasonic stirring, and then stirring the mixture at a high speed until the chitosan is completely dissolved; (2) under the condition of ultrasonic stirring, dropwise adding a silver nitrate aqueous solution to a chitosan solution obtained in Step (1), evenly stirring the mixture after addition, and then performing reduced pressure distillation to remove glacial acetic acid and water; (3) mixing a product obtained in Step (2) with silica sol and fluorinated-polyester-containing polymers, evenly stirring the mixture at a high speed, and then performing ultrasonic stirring. The invention further discloses the amphiphobic, antibacterial and easy-to-clean coating prepared with the method as well as an application of the coating to kitchen appliance products. The coating is easy to clean, acid-and-alkali-resistant, scratch-resistant, antibacterial and widely applicable to the kitchen appliance products.
