Abstract

The invention relates to a hydrophobic polyquaternary-ammonium-salt antistatic agent for oil products and a preparation method of the hydrophobic polyquaternary-ammonium-salt antistatic agent. The preparation method includes the steps of firstly, dissolving methyl acrylyl oxyethyl trimethyl ammonium chloride, long chain alkyl acrylate and initiator azodiisobutyronitrile into a low-molecular-weight alcohol solvent to form a monomer solution; secondly, adding a hydrocarbon solvent into a container, stirring, heating, and dropwisely adding the monomer solution obtained in the first step after the heating; thirdly, heating after the dropwise adding, and then preserving the heat; fourthly, washing the solution after the reaction in cold water, and stirring fast to obtain a crude product; fifthly, subjecting the crude product to vacuumizing filtration, and then performing vacuum drying to obtain the hydrophobic polyquaternary-ammonium-salt antistatic agent. The testing results obtained by using distilled aviation kerosene and standard base oil as testing oil show that the novel antistatic agent prepared by the method is excellent in antistatic performance and can be used as the antistatic agent for the oil products.

Description

technical field [0001] The invention relates to an antistatic agent for oil products, in particular to a hydrophobic polyquaternium salt antistatic agent for oil products and a preparation method thereof. Background technique [0002] During the process of storage, shipment and unloading of oil products, a large amount of static electricity will be generated due to friction, which will accumulate on the inner wall of the storage container and in the oil. When the static charge accumulates to a certain amount, electric sparks will be generated, which will cause accidents such as fire and explosion. Therefore, for petrochemical enterprises, preventing and controlling the occurrence of static electricity disasters in oil products is to reduce the accumulation of static charges to prevent accidents such as fire and explosion, and adding antistatic agents to oil products is one of the effective methods to eliminate static electricity hazards in oil products one. [0003] Oil an...
