Embodiment 1
[0026] formula:
[0027]
[0028]
[0029] Concrete preparation method comprises the following steps:
[0030] a. Add the high-pressure hydrogenated mineral oil of the vacuum residue at the bottom of the reactor in proportion to the reactor, and gradually heat up to 60°C during the stirring process;
[0031] b. Add octyl / butyl diphenylamine, low-basic calcium petroleum sulfonate, monoalkenyl butyrimide, acidic dibutyl phosphite, barium petroleum sulfonate and simethicone in proportion;
[0032] c. Stir for 45 minutes after all the addition, and filter through a 20um filter bag to obtain the finished chain oil.
