Embodiment 1
[0038] Embodiment 1: the preparation of antifouling, anti-fingerprint stainless steel plate water-based paint
[0039] Raw materials: see Table 1.
[0040] Preparation steps: a. Add the hydroxyl-modified water-based polyester resin in the formula to a neutralizer to adjust the pH to 8.5, and then add the modified silica sol, wetting agent, rheological additive, water-based polyethylene wax and polytetrafluoroethylene Ethylene wax (1:2 mass ratio) mixed slurry, nano-inorganic salt, and co-solvent are mixed evenly, stirred evenly at a speed of 1500-2000 rpm, and then ball milled for 1 hour;
[0041] b. Then slowly add defoamer, leveling agent, catalyst, adhesion promoter, deionized water under stirring at 800 rpm, stir for 15-30 minutes, then add methyl etherified amino resin and stir evenly for 150- The finished product can be packaged after being filtered by a 200-mesh sieve.
[0042] c. The above coating is baked at 170-180°C for 10 minutes to prepare a coating sample.

Abstract
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.
Description
technical field [0001] The invention relates to the field of special water-based paint materials, in particular to an anti-fouling and anti-fingerprint stainless steel plate water-based paint and a preparation method thereof. Background technique [0002] The baking paint used for processing parts basically adopts traditional oil-based baking paint, which is easy to cause serious harm to the human body and serious pollution to the environment, and brings hidden dangers in safety. Nowadays, the whole world advocates low carbon emissions, green and environmental protection, and it is necessary to develop water-based baking coatings. Patent CN101215438B discloses an anti-fouling and anti-aging stainless steel coating and its preparation method. This acrylic resin stainless steel coating has superior aging resistance and anti-ultraviolet performance, but a large amount of organic solvents are discharged, causing serious environmental air pollution.
