Problems solved by technology

Hydrocarbylaminomethylene - Sulfonic acid has strong polarity, and it can be used as an antistatic additive for fuel when used alone, but it is easy to ionize and form oxygen negative ions, which are easy to adsorb with metals, thereby reducing the conductivity of the antistatic additive and making the conductivity of fuel oil decay quickly and stabilize bad sex
During the actual production, transportation and storage of gasoline and diesel, since the pipes and large tanks in contact with them all belong to metal media, if hydrocarbylaminomethylene-sulfonic acids are used independently as antistatic additives, the conductivity of gasoline and diesel will decrease. It decays quickly to unqualified during transportation and storage, and the conductivity is lower than 50Ps / m

Abstract

The invention relates to a fuel additive and in particular relates to an anti-static fuel additive and a preparation method thereof. The anti-static fuel additive comprises polyamino sulfone shown in a formula (I). Amino and sulfonyl in the anti-static additive are in a same molecule, and the ratio of amino to sulfonyl is fixed, so that the anti-static additive can be also kept in gasoline or diesel in the absence of a stabilizer, the electrical conductivity of an oil product is stable, the production program of the anti-static additive is simplified, and the cost is lowered; and the anti-static additive is not easily adsorbed by metallic media, the electric conductivity of gasoline or diesel is not easily attenuated during transportation and usage processes, and the stability of the electrical conductivity is high.

Description

technical field [0001] The invention relates to a fuel additive, in particular to a fuel antistatic additive and a preparation method thereof. Background technique [0002] When loading, unloading or transporting petroleum and petroleum products, fire and explosion accidents caused by electrostatic discharge are common all over the world, causing huge economic losses. There are an average of 6 to 10 catastrophic accidents every year in the world, which occur during loading and unloading of oil. As for the accidents caused by electrostatic discharge of road oil tank cars and railway tank cars, they happen from time to time. Gasoline and diesel have poor electrical conductivity and tend to accumulate electric charge, resulting in static electricity disasters. With the development of the automobile industry in my country, the consumption of gasoline, diesel and other fuels is increasing year by year, and the static electricity ignition accidents that occur during the use of t...
