Embodiment Construction
[0014] An aging-resistant transparent heat-insulating nano-glass coating, made of the following raw materials in parts by weight (kg): 20 nanometer antimony tin oxide, dispersant SN-5040 0.2, water-based polyurethane resin 79, deionized water 30, N, N' -Dimethylformamide 40, 20% sulfuric acid solution 20, perfluorooctanoic acid 20, methyl methacrylate 3, potassium persulfate 0.1, isocyanate 3, DL-α-alanine 0.5, dimolybdenum boride 0.3, TiH 2 0.8.
[0015] The preparation method of the aging-resistant transparent heat-insulating nano-glass coating comprises the following steps:
[0016] (1) Mix nano-tin antimony oxide and perfluorooctanoic acid into N,N'-dimethylformamide, ultrasonicate for 30 minutes, then add sulfuric acid solution dropwise while stirring, and then heat to 80°C and stir for 20 minutes to complete the reaction. After the reaction, filter and vacuum dry to obtain fluorinated nano-indium tin oxide;
[0017] (2) Add dispersant SN-5040 and methyl methacrylate in...
