摘要

Static electricity is generated by friction during the storage, transportation, and handling of refined oils such as gasoline, diesel, and jet fuel. If not dissipated promptly, the accumulated charge can lead to spark discharge, which poses significant risks of fire and explosion. The incorporation of antistatic agents(ASAs) to increase fuel conductivity is among the most effective strategies for mitigating these electrostatic hazards. In this study, the polymer fragment modification method was employed to synthesize a series of economically viable and highly efficient polyquaternary ammonium salt type antistatic agents.Four hydrophobic long-chain alkyl acrylates, i.e., lauryl acrylate (LA), tetradecyl acrylate (TA), hexadecyl acrylate (HA), and stearyl acrylate (SA) were individually grafted onto the unsaturated carbon-carbon double bond of the water-soluble quaternary ammonium monomer, methacryloxyethyltrimethyl ammonium acetate (DMAc). This approach yielded antistatic agents that combine the inherent charge dissipation capability of quaternary ammonium salts with excellent oil matrix compatibility, while avoiding the generation of chlorinated pollutants during subsequent combustion processes. The structure and morphology of the polymeric product were characterized using instrumental analysis techniques, confirming its successful synthesis. Performance tests demonstrated that at an additive dosage of only 2 ppm, the DMAc-LA copolymer increased the conductivity of base diesel, jet fuel, and gasoline to 396, 270, and 876 pS/m, respectively. This study provides a new class of highly efficient antistatic agents for the electrostatic protection of fuels and offers practical insights for advancing polymer segment modification technologies.
