Embodiment 1
[0051] A preparation method of a high-temperature corrosion-resistant modifier, comprising the following steps:
[0052] 1) Add 100 parts of water-based epoxy resin, 30 parts of acrylic resin, 9 parts of isocyanate, and 6 parts of polyisobutylene into the reaction kettle, and stir and mix at 150°C for 2 hours until it is uniform and non-layered, and the color is uniform and thick;
[0053] 2) Cool to 85°C, add 10 parts of polyether-modified silicone, 6 parts of polysiloxane, 12 parts of ammonium polyphosphate, and 23 parts of castor oil polyglycidyl ether, and continue mixing and stirring for 1.5 hours;
[0054] 3) Cool to 45°C-50°C, add 12 parts of isopropylated triphenyl phosphate, 6 parts of polyurethane, and 12 parts of isocyanate and mix evenly to obtain a high-temperature corrosion-resistant modifier.
Embodiment 2
[0056] A preparation method of a high-temperature corrosion-resistant modifier, comprising the following steps:
[0057] 1) Add 100 parts of water-based epoxy resin, 45 parts of acrylic resin, 10 parts of isocyanate, and 5 parts of polyisobutylene into the reaction kettle, and stir and mix at 180°C for 1.5 hours until it is uniform and non-layered, and the color is uniform and thick;
[0058] 2) Cool to 90°C, add 13 parts of polyether-modified silicone, 5 parts of polysiloxane, 11 parts of ammonium polyphosphate, and 22 parts of castor oil polyglycidyl ether, and continue mixing and stirring for 1.5 hours;
[0059] 3) Cool to 45°C-50°C, add 10 parts of isopropylated triphenyl phosphate, 4 parts of polyurethane, and 9 parts of isocyanate and mix evenly to obtain a high-temperature corrosion-resistant modifier.
Embodiment 3
[0061] A preparation method of a high-temperature corrosion-resistant modifier, comprising the following steps:
[0062] 1) Add 100 parts of water-based epoxy resin, 48 parts of acrylic resin, 11 parts of isocyanate, and 5 parts of polyisobutylene into the reaction kettle, and stir and mix at 170°C for 2 hours until it is uniform and non-layered, and the color is uniform and thick;
[0063] 2) Cool to 95°C, add 18 parts of polyether-modified silicone, 7 parts of polysiloxane, 10 parts of ammonium polyphosphate, and 20 parts of castor oil polyglycidyl ether, and continue mixing and stirring for 1.5 hours;
[0064] 3) Cool to 50°C, add 12 parts of isopropylated triphenyl phosphate, 6 parts of polyurethane, and 11 parts of isocyanate and mix evenly to obtain a high-temperature corrosion-resistant modifier.
