Embodiment 1
[0040] In a container with stirring, add 80 ml of deionized water, heat to 55°C, add 0.016 g of Tween 80, 0.004 g of Kespan 60 in turn, stir and mix well, then add 16 g of 18-carbon straight-chain alkylamine and 4 grams of straight-chain alkylamines with 16 carbon atoms, stirred for 5-10 minutes and then cooled to room temperature to obtain an intermediate product. Add 60 grams of cyclohexylamine and 40 grams of ammonia water (referring to the weight of ammonia) in the reaction kettle, start stirring, then add 300 grams of morpholine, stir for 1-5 minutes, add the above-mentioned intermediate product, and stir for another 3 minutes to obtain milky liquid. Corrosion agent, the corrosion inhibition rate of the corrosion inhibitor is 98-99%.
Embodiment 2-13
[0042] The manufacturing steps and conditions of Examples 2-13 are the same as those of Example 1, the difference is that each raw material and the amount of raw materials are shown in Table 1, and the obtained corrosion inhibitor product is an emulsion liquid.
