Embodiment 1
[0021] The production of embodiment 1 epoxy xylenol formaldehyde conductive anticorrosion paint (1) synthesis of m-xylene formaldehyde resin
[0022] Mix and stir 100Kg of m-xylene, 12.2Kg of methanol, and 2.2Kg of boron trifluoride ether, react at 100°C for 1.5 hours, add 200Kg of formaldehyde, and dropwise add 4Kg of sulfuric acid, react for 3 hours, stop heating, and naturally cool to room temperature. After discharging, let stand to settle and separate, methanol reclaims, then neutralize to pH value 6~7 with the solution of sodium hydroxide 3.6Kg, water 8.5Kg; (2) Synthesis of m-xylenol-formaldehyde resin
[0023] Mix and stir 150Kg of phenol, 80Kg of formaldehyde, 2.25Kg of barium hydroxide, 150Kg of m-xylene formaldehyde resin, and 10Kg of methanol, react at 100°C for 1 hour, and vacuumize and dehydrate. (3) Synthesis of epoxy xylenol formaldehyde conductive static corrosion resistant coating
[0024] Mix 8Kg of E42 epoxy resin, 2Kg of m-xylenol aldehyde resin, 0.005Kg ...
