Detailed Description
The invention provides a ship gas turbine lubricating oil composition, which comprises the following components in percentage by weight:
base oil: 85% -98%;
compounding agent: 1.0% -3.0%;
pour point depressant: 0.2 to 0.5 percent;
a demulsifier: 0.01 to 0.03 percent
And (3) anti-foaming agent: 0.03 to 0.05 percent.
In the present invention, the base oil accounts for 85% to 98%, preferably 88% to 98%, and more preferably 90% to 97%, based on the total weight of the marine gas turbine lubricating oil composition. Base oils according to the present invention refer to base stocks or base stock blends of lubricating oil compositions, which are produced by a single manufacturer to the same specifications (independent of feed source or manufacturer's location); meet the specifications of the same manufacturer; and is identified by the unique recipe, the product identification code, or both. In the present invention, the base oil may be one or a mixture of group iii and group ii hydrogenated base oils. The present invention is not particularly limited as to the source and type of base oil, and can be any presently known or later-discovered base oil used in formulating lubricating oil compositions for any and all such applications, such as engine oils, marine cylinder oils, functional fluids such as hydraulic oils, gear oils, transmission oils, and the like. The gas turbine engine lubricating oil compositions for ships of the present invention can be prepared by one skilled in the art by conventional techniques using appropriate amounts of the disclosed base oils and conventional lubricating oil additives.
In the present invention, the compounding agent is contained in an amount of 1.0 to 3.0%, preferably 1.3 to 2.8%, more preferably 1.8 to 2.5%, based on the total weight of the ship gas turbine lubricating oil composition. In the invention, the complexing agent comprises alkyl arylamine, phosphate amine salt, 2, 6-di-tert-butylphenol, substituted triazole and mineral oil;
the alkyl arylamine accounts for 30-40% of the complexing agent, the phosphate amine salt accounts for 5-10%, preferably 6-8%, the 2, 6-di-tert-butylphenol accounts for 5-10%, preferably 5-9%, and the substituted triazole accounts for 1-5%, preferably 1-3%, of the complexing agent. The complexing agent is a lubricating oil additive specially applied to a medium-sized gas turbine, can meet the requirements of the lubricating oil of the gas turbine on rust resistance, corrosion resistance and high-temperature oxidation resistance, and has the advantages proved by physical and chemical indexes and bench tests.
In the present invention, the pour point depressant is contained in an amount of 0.2 to 0.5%, preferably 0.25 to 0.45%, and more preferably 0.3% based on the total weight of the ship gas turbine lubricating oil composition. The pour point depressant changes the shape, size and number of wax crystals through eutectic or adsorption, inhibits the lubricating oil from forming a crystal network and keeps the oil flowing. Those skilled in the art can select the addition within the above range according to the specific kind of the pour point depressant. The pour point depressant of the present invention is not particularly limited in its source, and may be commercially available. In a specific embodiment of the present invention, the pour point depressant is preferably an acrylate polymer solution, wherein the acrylate copolymer concentration is 40% to 70%.

The lubricating oil inevitably generates water or water vapor in use, and then the lubricating oil and the water are mixed together to cause emulsification of the lubricating oil. The emulsified oil product can damage equipment, and meanwhile, acidic substances capable of corroding the equipment are generated, so that the corrosion and abrasion of the equipment are accelerated, and the service life of the equipment is shortened. The demulsifier can quickly separate lubricating oil from water, thereby avoiding the emulsification of the lubricating oil and playing a role in protecting equipment. In a particular embodiment of the invention, the demulsifier is preferably a polyether glycol polymer.
In the present invention, the anti-foaming agent is contained in an amount of 0.03 to 0.05%, preferably 0.035 to 0.045%, based on the total weight of the ship gas turbine lubricating oil composition. The antifoaming agent acts as a surfactant, and reduces the local surface tension of the lubricant, and is adsorbed on the surface of the bubbles or invades into the bubbles to cause the collapse of the foam. The source of the antifoaming agent of the present invention is not particularly limited, and commercially available products are acceptable. In particular embodiments of the present invention, the preferred anti-foam agent is a non-silicone polymer.
The preparation method of the gas turbine lubricating oil composition for ships adopts a conventional preparation method in the field. In the embodiment of the present invention, the components described in the above scheme are preferably mixed to obtain a transparent and uniform mixture, i.e., the gas turbine lubricating oil composition for ships of the present invention.
