The invention relates to the technical field of antistatic agents, and particularly discloses an oil product
antistatic agent and a preparation method thereof. The modified
polysulfone is obtained by mixing and treating the following raw materials in parts by
mass: 35-40 parts of
xylene, 20-25 parts of composite
polyamine, 15-20 parts of
polysulfone, 5-8 parts of oligomeric
dopamine and 1-2 parts of an activating agent, the preparation method comprises the following steps: taking composite
polyamine, mixing with oligomeric
dopamine, dispersing with
xylene, then adding an activator, stirring, then adding
polysulfone, and continuously treating, thereby obtaining the product. The preparation method of the composite
polyamine comprises the following steps: taking
epichlorohydrin, dispersing, adding a mixed amine source, heating, adding
sodium carbonate, continuously stirring, cooling, adding a deprotection agent, filtering
after treatment, taking a liquid part,
drying by
distillation, washing,
drying again, and
grinding to obtain the composite polyamine. The oil product
antistatic agent prepared by the invention has relatively strong antistatic capability and relatively long
duration time, and can form a firmer double-electric-layer structure.
