Description
Technical field
The present invention relates to a kind of fuel dope, specifically, relate to a kind of fuel anti static additive and preparation method thereof.
Background technology
Handling or transportation oil and petroleum products, the fire causing because of static discharge, explosion hazard are at whole world ubiquity, and the financial loss causing is very huge.The every annual in the whole world has Extra Serious Accident 6～10 times, when charge of oil, emptying, occurs.As for road tank car and rail tank car, because of the accident that static discharge causes, happen occasionally.Gasoline, diesel oil poorly conductive, easily gather electric charge, and electrostatic hazard accident occurs.Along with automotive industry is the developing of China, the usage quantity increase year after year of the fuel such as gasoline, diesel oil, and the static firing accident that these fuel in use occur grows with each passing day.Therefore gasoline, diesel oil are used anti static additive very necessary.
The anti static additive that China is used at present mainly contains the anti static additives such as T1502, Stadis450, Stadis425, T1503.T1502 and Stadis450 are the ashless anti static additives of rocket engine fuel, and they have good antistatic effect in rocket engine fuel.Stadis425 and T1503 are the ashless anti static additives of gasoline, diesel oil.They have good antistatic effect in gasoline, diesel oil.
Existing anti static additive is by polysulfones, two kinds of polymers of polyamine and solvent composition.The mechanism of action of existing anti static additive is that polysulfones can lose proton and electronegative, and polyamine easily obtains proton and positively charged, when they meet, forms strong dipole ion pair owing to attracting each other, and is not having under outer electrostatic field, and ion pair is aobvious neutral.Once there be outer electrostatic field to exist, the dipole ion that polysulfones and polyamine form is to aligning, electronegative polysulfones one end turns to outer electrostatic field anodal, polyamine one end of positively charged turns to external electric field negative pole, form dipole ion pair, form contrary " polarized electric field " with external electric field polarity, thereby reduced external electric field intensity, play antistatic property.If outer electrostatic field is very strong, this dipole ion, to being finally separated into and being with plus-minus electric ion under the inductive capacity effect very strong, shows stronger electroconductibility.Polyamine, polysulfones comprise difference but the polar group polymer that attracts each other, mix according to a certain percentage, due to the effect of intermolecular attraction, make the polar group can not be in the state of rolling up, it is many when rolling up to be exposed to outer polar group, thereby strengthens electroconductibility.But polar group to align mobile time distance larger, therefore except being subject to outside the impact of electrostatic field power, be subject to oil product structure and extraneous factor to affect larger as factors such as temperature, times.
US Patent No. 3844732A proposes with alkyl aminomethylene-sulfonic acid as fuel anti static additive.Alkyl aminomethylene
-sulfonic acid polarity is strong, and it uses separately the anti static additive that can be used as fuel, but its easily ionizable forms negative oxygen ion, and easy and metal adsorption, thereby the conductive capability of reduction anti static additive make the specific conductivity decay of oil fuel fast, and stability is not good.In vapour, diesel oil actual production, transportation and storage process, because the pipeline of contact, large tank etc. all belong to metal medium, if used as anti static additive alkyl aminomethylene-sulphonic acids is independent, the specific conductivity of vapour, diesel oil will decay to very soon defective in transportation and accumulating, and specific conductivity is lower than 50Ps/m.
For the defect of anti static additive in prior art, special proposition the present invention.

Fuel anti static additive in the present invention and the chemical structure of anti static additive of the prior art and composition and the mechanism of action are all different.Fuel anti static additive of the present invention is by a kind of polymer of polyamine base sulfone and solvent composition.
The chemical structure of poly-amino sulfone is suc as formula shown in I:
The antistatic property mechanism of fuel anti static additive of the present invention is: anti static additive, because the amido of positively charged and electronegative sulfuryl are in same molecular structure, is not having under outer electrostatic field, and molecule is aobvious neutral.When having outer electrostatic field, can form ion pair in molecule, form contrary " polarized electric field " with external electric field polarity, thereby reduced external electric field intensity, play antistatic property.Due to ion pair in molecule to align miles of relative movement less, be subject to oil product structure and extraneous factor to affect less as factors such as temperature, times.
Beneficial effect of the present invention is:
1. anti static additive of the present invention is because the amido of positively charged and electronegative sulfuryl are in same molecular structure, when having outer electrostatic field, can form ion pair in molecule, form contrary " polarized electric field " with external electric field polarity, thereby reduced external electric field intensity, played antistatic property.Due to ion pair in molecule to align miles of relative movement less, in the higher diesel oil of molecular weight, in molecule, in molecule, ion pair spacing is short, the polarized electric field of formation is strong.The ability that derives electric charge increases, so the specific conductivity of anti static additive of the present invention in diesel oil is high.
2. amido and sulfuryl are in same a part, and the ratio of amido and sulfuryl is fixed, and do not need stablizer also can keep anti static additive in vapour, diesel oil, and the stable conductivity of oil product has been simplified the production sequence of static inhibitor, has reduced cost.
Due to ion pair in molecule to align miles of relative movement less, be subject to oil product structure and extraneous factor to affect less as factors such as temperature, times.Therefore the stable conductivity of anti static additive of the present invention in vapour, diesel oil is good, is subject to external interference little.Compare with alkyl aminomethylene-sulphonic acids anti static additive, poly-amino sulfone in the present invention is done vapour, diesel oil anti static additive, it is difficult for being adsorbed by metal medium, and gasoline, diesel oil specific conductivity in transportation and use procedure is difficult for decay, and the stability of specific conductivity is high.
The specific embodiment of the present invention only limits to further explain and explanation the present invention, not to Composition of contents restriction of the present invention.
