Embodiment 1
[0016] An anti-corrosion coating for power systems, which is composed of the following raw materials in parts by weight: 23 parts of organic fluorosilicone resin, 18 parts of vulcanized rubber, 13 parts of carbon nanotubes, 26 parts of composite conductive filler, 1 part of ammonium polyphosphate, and 6 parts of propanol , 3 parts of butyl glycidyl ether, 2 parts of zinc stearate, 2 parts of silane coupling agent and 1 part of bentonite.
[0017] Step 1: Add carbon nanotubes to mixed acid and stir with a magnetic stirrer, then condense and reflux, react at 60°C for 2h, then wash with deionized water until neutral, then suction filter, and vacuum dry at 80°C for 24h to obtain Modified carbon nanotubes;
[0018] Step 2, put the composite conductive filler, butyl glycidyl ether, zinc stearate and ammonium polyphosphate into a ball mill, grind for 15 minutes at a speed of 1200 rpm, and then filter the mixture with a 150-mesh sieve;
[0019] Step 3, put organic fluorosilicone resi...

[0023] Step 1: Add carbon nanotubes to mixed acid and stir with a magnetic stirrer, then condense and reflux, react at 75°C for 3h, then wash with deionized water until neutral, then vacuum-dry at 90°C for 24h to obtain Modified carbon nanotubes;
[0024] Step 2, put the composite conductive filler, butyl glycidyl ether, zinc stearate and ammonium polyphosphate into a ball mill, grind at a speed of 1500 rpm for 20 minutes, and then filter the mixture with a 200-mesh sieve;
[0025] Step 3, put organic fluorosilicone resin, vulcanized rub...
Embodiment 3
[0028] An anti-corrosion coating for power systems, which is composed of the following raw materials in parts by weight: 32 parts of organic fluorosilicone resin, 28 parts of vulcanized rubber, 23 parts of carbon nanotubes, 40 parts of composite conductive filler, 5 parts of ammonium polyphosphate, and 25 parts of propanol , 6 parts of butyl glycidyl ether, 5 parts of zinc stearate, 5 parts of silane coupling agent and 3 parts of bentonite.
[0029] Step 1: Add carbon nanotubes to mixed acid and stir with a magnetic stirrer, then condense and reflux, react at 90°C for 4h, then wash with deionized water until neutral, then vacuum-dry at 95°C for 24h to obtain Modified carbon nanotubes;
[0030] Step 2, put the composite conductive filler, butyl glycidyl ether, zinc stearate and ammonium polyphosphate into a ball mill, grind for 25 minutes at a speed of 1800 rpm, and then filter the mixture with a 260-mesh sieve;
[0031] Step 3, put organic fluorosilicone resin, vulcanized rub...
