Embodiment 1
[0031] Step 1, steel substrate surface pretreatment: First, the surface of the steel substrate workpiece was ultrasonically cleaned with acetone for 30 minutes, then ultrasonically degreased with sodium hydroxide solution (mass fraction 2-8%) for 10 minutes, and finally polished with 120-mesh sandpaper ( provide a cleaner, rougher, more reactive surface for subsequent coatings);
[0032] Step 2, preparation of high-purity aluminum dihydrogen phosphate binder: Pour a phosphoric acid solution with a mass fraction of 65% into a three-necked flask, then add aluminum hydroxide powder (purity is 99.99%), mix and stir evenly at 120°C Carry out the oil bath for 1h to obtain the liquid aluminum dihydrogen phosphate finished product, and the molar ratio of phosphoric acid to aluminum hydroxide is 2.14:1;
[0033] Step 3, preparation of alumina insulating coating: 30g of aluminum dihydrogen phosphate binder, 60g of water, and 90g of nano-alumina are mixed uniformly and ball-milled for 5 ...

[0036] Step 2, preparation of high-purity aluminum dihydrogen phosphate binder: Pour a phosphoric acid solution with a mass fraction of 65% into a three-necked flask, then add aluminum hydroxide powder (purity is 99.99%), mix and stir evenly, and heat at 130°C Carry out the oil bath for 1h to obtain the liquid aluminum dihydrogen phosphate finished product, and the molar ratio of phosphoric acid to aluminum hydroxide is 2.16:1;
[0037] Step 3, preparation of alumina insulating coating: 8g of aluminum dihydrogen phosphate binder, 16g of water, 23.8g of nano-alumina, 2.0g of nano-magnesium oxide were ...
Embodiment 3
[0039]Step 1, steel substrate surface pretreatment: First, the surface of the steel substrate workpiece was ultrasonically cleaned with acetone for 30 minutes, then ultrasonically degreased with sodium hydroxide solution (mass fraction 2-8%) for 10 minutes, and finally polished with 120-mesh sandpaper ( provide a cleaner, rougher, more reactive surface for subsequent coatings);
[0040] Step 2, preparation of high-purity aluminum dihydrogen phosphate binder: Pour a phosphoric acid solution with a mass fraction of 65% into a three-necked flask, then add aluminum hydroxide powder (purity is 99.99%), mix and stir evenly, and heat at 140°C Carry out oil bath 1h, promptly make liquid aluminum dihydrogen phosphate finished product, and the molar ratio of phosphoric acid and aluminum hydroxide is 3.12:1;
[0041] Step 3, preparation of alumina insulating coating: 9g of aluminum dihydrogen phosphate binder, 27g of water, 36g of nano-alumina, and 1.5g of nano-magnesia were uniformly mi...
