The invention discloses anti-fingerprint powder coating and a preparation method and application thereof. The anti-fingerprint powder coating is prepared from, by weight, 20-40 parts of composite polyester resin A, 30-50 parts of polyester resin B and 0-30 parts of other auxiliary agents. The preparation method includes: well mixing hydroxyl polyester resin and a composite material, subjecting tomelt extrusion through a double-screw extruder, cooling sheets to the normal temperature, and crushing to obtain the composite polyester resin A; adding the composite polyester resin A, the polyesterresin B and other auxiliary agents into a premixing tank, well mixing, subjecting to melt extrusion through a double-screw extruder, cooling sheets to the normal temperature, and finally crushing andgrading through a high-speed crusher to obtain powder in particle size of 33-38micron. By synergistic effects of the composite polyester resin A and the polyester resin B, a formed coating is easy toclean and remarkable in anti-fingerprint performance, automatic fingerprint clearing is realized, and the powder coating is silky and smooth to touch and especially suitable for terminal products including furniture, door and window accessories, decorative lamps, electronic communication equipment and the like and manifests high end and elegance of products.

The invention provides a method for preparing AF coated glass with antibacterial effect, comprising the following steps: S1, ultrasonically cleaning the glass substrate with a solvent or cleaning agent, then rinsing with deionized water, and blowing dry with nitrogen; S2, Coating a layer of SiO on the glass substrate by vacuum coating 2 Film base layer; S3. Add nano-silver to the anti-fingerprint agent, and spray the treated anti-fingerprint agent evenly onto the SiO on the surface of the glass substrate by a spraying machine. 2 On the base layer of the film, then dry the glass substrate, take it out and cool it, so as to form an antibacterial and anti-fingerprint layer; S4, disperse SiO in a solvent 2 Particles and nano-silver are prepared into an antibacterial coating solution, and the antibacterial solution is evenly sprayed on the antibacterial and anti-fingerprint layer of the glass substrate by a spraying machine, and then the glass substrate is dried, taken out and cooled to form an antibacterial SiO 2 film layer. The coated glass of the invention has anti-fingerprint and antibacterial effects.

The invention discloses anti-fouling and fingerprint-resistant stainless steel plate water-based paint and a preparation method thereof. The anti-fouling and fingerprint-resistant stainless steel plate water-based paint is prepared from, by weight, 55-70% of hydroxy modified waterborne polyester resin, 8-15% of methylated amino resin, 3-5% of modified silica sol, 2-4% of a neutralizing agent, 0.1-0.3% of a wetting agent, 0-0.2% of theological additives, 0.1-1.5% of a defoaming agent, 0.1-0.5% of a flattening agent, 3-6% of aqueous polyethylene wax and polytetrafluoroethylene wax mixed paste, 1-3% of an adhesive force promoting agent, 1-3% of nanometer inorganic salt, 0.2-0.5% of a catalyst, 3-5% of a cosolvent and 1-8.5% of deionized water. The anti-fouling and fingerprint-resistant stainless steel plate water-based paint has excellent fingerprint resistance and hydrophobicity and oleophobicity, and is large in fingerprint-resistant coating water contact angle and oil contact angle, small in sliding angle, and excellent in abrasion resistant and aging resistance, and greasy dirt is prone to sliding. Meanwhile, the anti-fouling and fingerprint-resistant stainless steel plate water-based paint is environmentally friendly and healthy, and the method is simple.
