Background
The gasoline additive is used for making up the quality problem of fuel oil and the defects of mechanical manufacturing limit of motor vehicles, thereby improving the combustion performance of gasoline and prolonging the service life of gasoline engines. Along with the continuous operation of a vehicle, the gasoline engine can unconsciously generate substances which influence the normal operation of the automobile, such as oil sludge, carbon deposition and the like in departments such as an oil nozzle, a cylinder and the like in the engine.

Disclosure of Invention
In order to solve the technical problems, the invention provides a high-efficiency antistatic gasoline additive, which at least comprises the following components in parts by weight: 20-60 parts of combustion improver, 10-35 parts of shock-resistant agent, 1-2.5 parts of antistatic agent, 1-6 parts of surfactant, 0.2-1 part of antiknock agent and 0.1-1 part of corrosion inhibitor.
As a preferred technical scheme, the combustion improver at least comprises a hydrocarbon and a derivative thereof.
In a preferred embodiment, the hydrocarbon or the derivative thereof contains at least one oxygen atom in the molecule.
Preferably, the hydrocarbon and its derivatives are at least one selected from alkanes, alcohols, alcohol ethers, ketones, esters and ethers.
As a preferable technical scheme, the alcohol is a mixture of methanol and propylene glycol, and the mass ratio of the methanol to the isopropanol is (1-10): 1.
as a preferable technical scheme, the alcohol is a mixture of methanol and propylene glycol, and the mass ratio of the methanol to the isopropanol is (5-10): 1.
in the using process of the gasoline, the gasoline can not be completely combusted, harmful gases such as CO, NOx and the like can be generated, and the harmful gases discharged into the environment can greatly pollute the environment, influence the air quality and even harm the human health. The inventor unexpectedly finds that by adding a certain amount of mixture of methanol and isopropanol, the oxygen content of the gasoline can be increased, the fuel can be fully combusted, the emission of harmful gas can be reduced, the power performance of a gasoline engine can be improved, the flameout phenomenon caused by insufficient fuel supply can be reduced, the freezing resistance of the gasoline can be improved, and the accumulation of deposited carbon in the combustion process of the gasoline can be reduced. However, when the amount of the isopropyl alcohol is too large, the volatility of the whole gasoline product is reduced, and the long-term stability of the gasoline product is affected, but when the amount of the isopropyl alcohol is small, the power performance of the gasoline engine cannot be reduced, and the phenomenon of flameout caused by insufficient fuel supply is reduced. The inventor thinks that the possible reasons are that part of bubbles are generated due to shaking in the process of fuel supply of gasoline, the generated bubbles can block the circulation of the gasoline in an oil way, so that the phenomenon that the gasoline engine is not supplied with fuel timely and flameout occurs, the bubble property of the whole gasoline product is reduced due to the addition of methanol and isopropanol, and when bubbles occur, the surface tension of the bubbles can be reduced to rapidly break the bubbles, so that the flameout phenomenon caused by the fuel supply failure is reduced.
As a preferred technical solution, the anti-seismic agent is at least one selected from petroleum and its derivatives, vegetable oil and animal oil.
As a preferred technical scheme, the petroleum and the derivatives thereof are heavy naphtha.
As a preferred embodiment, the antistatic agent is T1503.
The antistatic agent used in the technical scheme is T1503, and T1503 has a good antistatic effect, good fluidity and easy addition, but the polysulfone and polyamine in T1503 have high positive and negative ion movement speeds, so that the conductivity decay speed is easy to be over high.
As a preferred technical scheme, the surfactant is an anionic surfactant and/or a nonionic surfactant.
As a preferable technical solution, the anionic surfactant is a sulfonate surfactant.
As a preferable technical scheme, the HLB of the sulfonate surfactant is 11-13.
As a preferable technical scheme, the nonionic surfactant is fatty alcohol-polyoxyethylene ether.
As a preferred technical solution, the surfactant is a mixture of an anionic surfactant and a nonionic surfactant, and the mass ratio of the anionic surfactant to the nonionic surfactant is 1: (3-5).
Because methanol and propylene glycol contain hydroxyl with stronger polarity, the problem of compatibility can occur when the methanol and propylene glycol are added into gasoline, when the inventor adds certain anionic surfactant and nonionic surfactant, especially when the HLB of sulfonate anionic surfactant is 11-13, the compatibility between alcohol and oil can be better improved, and the cleanness and antistatic property of the whole gasoline product can also be improved, hydrophilic groups in the surfactant are tightly adsorbed on an oil-alcohol interface, so that the surface tension can be effectively reduced, the Brownian motion between methanol and isopropanol liquid beads is hindered, the liquid beads are not easy to aggregate and grow, and the intersolubility of the methanol, the isopropanol and the gasoline is improved. And the cleanness and antistatic property of the gasoline product can be improved by adding the surfactant. The inventor believes that probably due to the combined action of the fatty acid sulfonate and the fatty alcohol-polyoxyethylene ether, micelles formed in the fatty acid sulfonate and the fatty alcohol-polyoxyethylene ether are doped and wound mutually, so that the formation of the interactions of the micelles is avoided, oil sludge and carbon deposit are gathered and adhered to the surface of a gasoline engine, meanwhile, the micelles are also prevented from being gathered to form precipitates, and the storage stability of the additive is improved; meanwhile, due to the combined action of the fatty acid sulfonate and the fatty alcohol-polyoxyethylene ether, the distance between positive and negative ions of polysulfone and polyamine in the antistatic agent is increased, the directional arrangement of a dipole ion pair formed by the polysulfone and the polyamine is inhibited, part of the dipole ion pair formed by the polysulfone and the polyamine is reduced, the movement speed of the positive and negative ions of the polysulfone and the polyamine is reduced to a certain extent, the conductivity of gasoline is further stabilized, and the conductivity resistance of the whole gasoline product is improved. When the HLB of the fatty acid sulfonate is low or high, dispersion of charges and compatibility with other substances are not facilitated, and cleanliness and storage stability may be lowered.
As a preferred technical scheme, the antiknock agent is polyisobutylene succinimide.
The inventor unexpectedly finds that the anti-explosion performance of the gasoline additive can be improved and the antistatic effect of the gasoline additive can be improved by adding a certain amount of polyisobutylene succinimide. The polyisobutylene succinimide can damage peroxide generated in a gasoline engine, so that the concentration of the peroxide in a flame front reaction is reduced, and meanwhile, a part of chain reaction is selectively interrupted, so that automatic ignition is hindered, the speed of releasing energy is slowed down, the anti-knock property of fuel is improved, the amino in the polyisobutylene succinimide can conduct electric charges generated in a gasoline product, the electric charges are leaked out in time, and the antistatic property, the safety and the stability of the product are improved.
As a preferable technical scheme, the corrosion inhibitor is quaternary ammonium salt.
As a preferable technical scheme, the quaternary ammonium salt is cetyl trimethyl ammonium bromide.
The inventor selects quaternary ammonium salt as the corrosion inhibitor, which not only can form an adsorption film on the surface of the gasoline engine to prevent the gasoline engine from being corroded and protect the performance of the gasoline engine, but also can conduct charges generated in the gasoline product, so that the charges are leaked out in time, and the antistatic property, the safety and the stability of the product are improved.
The second aspect of the invention provides a preparation method of the high-efficiency antistatic gasoline additive, which at least comprises the following steps: physically mixing combustion improver, shock-resistant agent, surfactant, antistatic agent, dynamic accelerator and corrosion inhibitor.

Has the advantages that: according to the technical scheme, the combustion performance of the gasoline is improved by adding a certain combustion improver, so that the gasoline fuel is fully combusted, the emission of harmful gases can be reduced, and the combustion performance of the gasoline can be improved. The inventor adds a certain surface cleaning agent, so that the accumulation of oil sludge and carbon deposit on the gasoline engine when the gasoline is used is reduced, and the combustion power of the gasoline engine is further improved. The inventor adds certain corrosion inhibitor and antistatic agent to improve the antistatic property and the protection property to the gasoline engine when the gasoline fuel is used.
