Embodiment 1
[0010] Take 85.5 parts of bisphenol A glycidyl ether, 14.5 parts of epoxy resin with an equivalent weight of 371, 27.5 parts of bisphenol A and 15 parts of N-methylethanolamine by weight in the raw materials of this high-efficiency anti-corrosion coating. Base material, then take 100 parts of base material, 50 parts of methyl isobutyl ketone, 64 parts of polyisocyanate, 50 parts of talcum powder, and 50 parts of coal tar according to the weight ratio, mix and stir evenly, and put them into the reaction kettle And keep the temperature at 200-220°C, such as reacting at 210°C for about 20-40 minutes, you can get this high-efficiency anti-corrosion coating.
Embodiment 2
[0012] In this embodiment, each step is consistent with implementation 1, except that the weight ratio of each raw material of the preparation base material is 82 parts of bisphenol A glycidyl ether, 11 parts of epoxy resin with an equivalent weight of 371, 24 parts of bisphenol A, and N-methyl ether. 12 parts of ethanolamine. And when further preparing coating, the weight ratio of each raw material is base material 90 parts, methyl isobutyl ketone 45 parts, polyisocyanate 60 parts, talcum powder 40 parts, coal tar 40 parts.
Embodiment 3
[0014] In this embodiment, each step is consistent with implementation 1, except that the weight ratio of each raw material of the preparation base material is 89 parts of bisphenol A glycidyl ether, 17 parts of epoxy resin with an equivalent weight of 371, 30 parts of bisphenol A, and N-methyl ether. 18 parts of base ethanolamine. And when further preparing coating, the weight ratio of each raw material is 110 parts of base material, 55 parts of methyl isobutyl ketone, 70 parts of polyisocyanate, 60 parts of talcum powder, 60 parts of coal tar.
