Abstract
The invention relates to an oil product rust-proof additive, a preparation method thereof and an oil product composition. The additive is prepared from unsaturated fatty acid or unsaturated fatty acid ester serving as a raw material through addition reaction and hydrolysis reaction. The antirust agent product provided by the invention has the characteristics of simple preparation process, wide sources of production raw materials, low preparation cost, small additive amount in oil products and the like, and has excellent rust resistance in the oil products.
Description
Technical Field
The invention relates to the field of fuel and lubricating oil, in particular to an oil additive, a preparation method thereof and an oil composition.
Background
The fuel oil inevitably contains dissolved water and even small amounts of free water. Rust may occur when aqueous fuel oil comes into contact with vessels, pipelines, oil pumps, etc. The organic acid formed by oxidative deterioration of the fuel oil in turn promotes corrosion of the metal. In addition, non-hydrocarbon compounds in oil products such as sulfur and sulfur-containing compounds, organic acids, water-soluble acids or bases, moisture additives, bacteria, and the like can also cause corrosion of metals. For example, in the process of oil storage and transportation, moisture can enter the tank through the breather valve, and water can enter the underground tank due to leakage of rainwater. Water has higher conductivity than oil and electrochemical corrosion is formed by contact of water with metal. In addition, organic acids in oil and acidic substances dissolved in water can rust metals.
For gasoline fuels, the corrosiveness of gasoline is exacerbated by the wide use of alcohol compounds to increase octane number. On one hand, the alcohol compound has a corrosion effect; on the other hand, alcohol gasoline can dissolve more water, and the polarity of the hydrocarbon and alcohol mixture can reduce the ability of the surfactant to adsorb on the metal surface, and can also exacerbate the corrosion of the metal by gasoline.
The presence of corrosive substances in fuel oil can bring a series of hazards to the storage and transportation and use of fuel oil: destroying the metal components of the oil reservoir and the engine fuel system, reducing its life; pollution of fuel, influence on filtration and oil injection; erosion of rubber and destruction of seals, resulting in oil leakage; the stability of the fuel is reduced, the generation of colloid and sediment is promoted, and the quality of the fuel is reduced; increase the wear of the machine parts, etc.
In order to reduce the harm of corrosion effect to oil products and mechanical parts, the addition of an anti-rust agent (slow release agent) to the oil products is an efficient and feasible method. The rust inhibitor is a high-efficiency synthetic penetrating agent, and can forcefully penetrate into rust, corrosive substances and greasy dirt so as to easily remove the rust, corrosive substances and greasy dirt. The rust inhibitor has the performances of penetrating rust removal, loosening lubrication, corrosion resistance, metal protection and the like. The reasonable use of rust inhibitor is an economical and effective protection technique for preventing metals and alloys thereof from being corroded.
Currently, three main categories of metal rust inhibitors are: imidazolines; naphthenic acids such as sulfonated alkylphenol, mercaptotriazine compound, fatty acid aminoamide, N' -dihydroxyethylpiperazine, and the like; a hybrid type. The rust inhibitor products currently used in China are listed in Table 1.
Table 1 rust inhibitor commodity
Along with the improvement of the attention of metal rust problems, the development technology of metal rust inhibitors has a plurality of reports.
Patent US4445907 discloses a method ofAn alcohol fuel rust inhibitive additive as an active ingredient, wherein NH-R' is an aminotetrazolyl group. The component can be used as an anti-rust additive of alcohol fuel to show good anti-rust performance, but has high preparation difficulty and high preparation cost.
WO2008095805A3 discloses a composition containing a triazole metal deactivatorThe metal corrosion inhibitor of the borate component and the amine phosphate component has complex composition, high preparation difficulty and high preparation cost.
Patent CN1087667a discloses an alcohol fuel metal antirust agent which is formed by diluting and blending benzotriazole, dimerized linoleic acid corrosion inhibitor and hindered phenol antioxidant, and has the advantage of mild preparation conditions, but the benzotriazole compound is toxic and does not meet the requirements of green additives, and the antirust agent composition has larger additive amount in base fuel, so that the use cost of the antirust agent is higher.
Patent CN1597876a discloses a functional additive for inhibiting metal corrosion, which is a composition composed of magnesium inorganic compound, solvent oil, organic acid and accelerator, and the main component of the additive with rust-proof property is an oil-soluble magnesium salt. However, the composition of the additive is complex and the preparation difficulty is high.
Patent CN102286300B discloses a metal corrosion inhibitor and a preparation method thereof, which is a composition composed of ethylene glycol monomethyl ether, methacrylate oligomer and polypropylene glycol, and the additive is added into fuel in an amount of 0.02% -0.03%. The additive is an ashless additive, but the preparation process of the additive is complex, and the process parameters are difficult to regulate and control.
