Example Embodiment
[0027] Example 1
[0028] Weigh out 55 parts of 90# straight-run asphalt (penetration of 150) (by weight, the same below), 21 parts of cetylpyridinium bromide, 7 parts of methyl coconut oleate polyoxyethylene ether, and 12 parts of alginic acid Parts, 10 parts of carboxyl-terminated polyoxypropylene ether, 60 parts of water. The above-mentioned asphalt is heated to 140°C, and then the above-mentioned other raw materials are prepared into an aqueous solution of 50°C, and then the asphalt and the aqueous solution are passed through an emulsifying device to obtain the emulsified asphalt anticorrosive coating product of the present invention.
Example Embodiment
[0029] Example 2
[0030] Weigh 55 parts of 100# straight-run asphalt (penetration of 150) (by weight, the same below), 17 parts of cetylpyridinium bromide, 5 parts of methyl coconut oleate polyoxyethylene ether, and 9 parts of alginic acid Parts, 8 parts of carboxyl-terminated polyoxypropylene ether, 45 parts of water. The above-mentioned asphalt is heated to 150°C, and the above-mentioned other raw materials are prepared into an aqueous solution at 60°C, and then the asphalt and the aqueous solution are passed through an emulsifying device to obtain the emulsified asphalt anticorrosive coating product of the present invention.
