Description

Technical Field

[0001] The present invention relates to a wear-resistant, lubricating and rust-proof oil and a preparation method thereof, belonging to the technical field of rust-proof oils. Background Art

[0002] During the storage, transportation and use of metals, due to the influence of substances such as water vapor, oxygen, acids, alkalis, salts and carbides in the environment, under certain conditions of temperature, humidity and time duration, physical and chemical changes are likely to occur, resulting in rusting. The rusting of metals will cause losses of metals and the decline and loss of the functions of metal parts, greatly damage the performance and commercial value of metal products, and even cause major failures and lead to the scrapping of equipment. To avoid rusting, various technologies and methods have been adopted to prevent metal corrosion. Among them, using rust-proof oil to protect metal products is one of the most commonly used protection methods at present.

[0003] Currently, the composition of rust-proof oils on the market usually includes oil-soluble rust inhibitors, base oils and various auxiliary additives. The rust inhibitors used are usually alkaline earth metal salts of fatty acids or naphthenic acids, lead naphthenate, zinc naphthenate, etc. Although these rust-proof oils can achieve a certain degree of rust-proof effect to some extent, they generally have problems such as poor rust-proof performance and short rust-proof time. And under certain application requirements and working conditions, such as the storage, transportation and operation of internal combustion engines, the rotational movement of the spindle systems of CNC lathes, milling machines, etc., the processing and operation of micro-precision bearings and bearings in various mechanical equipment, the requirements for the rust-proof performance of rust-proof oils are relatively high, and the rust-proof oil also needs to play roles such as lubrication, sealing and buffering for mechanical processing parts. Therefore, these conventional rust-proof oils on the market cannot meet the performance requirements. Summary of the Invention

[0004] The object of the present invention is to provide a rust-proof oil with good rust-proof performance, long rust-proof time and wear-resistant lubricating performance and a preparation method thereof, aiming at the problems of poor rust-proof performance, short rust-proof time and insufficient lubricating ability under special use conditions of existing rust-proof oils.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A wear-resistant, lubricating and rust-proof oil contains the following components in parts by weight:

[0007]

[0008]

[0009] Further, the sulfonate rust inhibitor is selected from one or a mixture of at least two of barium petroleum sulfonate, sodium petroleum sulfonate, calcium petroleum sulfonate, barium dinonylnaphthalene sulfonate, barium heavy alkylbenzene sulfonate or non-barium heavy alkylbenzene sulfonate, and preferably a mixture of barium petroleum sulfonate and calcium petroleum sulfonate.

[0010] Further, the organic acid rust inhibitor is selected from one or a mixture of at least two of dodecenyl succinic acid, dodecenyl succinic anhydride, heptadecenyl imidazoline alkenyl succinate or zinc naphthenate, and preferably a mixture of dodecenyl succinic acid and zinc naphthenate.

[0011] Further, the hydrocarbon base oil is selected from one or a mixture of at least two of D40 solvent oil, D60 solvent oil, D80 solvent oil, 120# solvent gasoline or kerosene.

[0012] Further, the mineral oil is selected from one or a mixture of at least two of L-AN total loss system oil, metal cleaning oil, transformer oil, spindle oil, 100N base oil, 150N base oil, 100SN base oil or 150SN base oil.

[0013] Further, the oil solvent is selected from one or a mixture of at least two of span-80, vegetable oleic acid, palmitic acid or stearic acid.

[0014] Further, the film-forming agent is selected from any one or a mixture of at least two of oxidized paraffin wax, lanolin, lanolin magnesium soap, lanolin aluminum soap, lanolin calcium soap, petrolatum, barium soap of oxidized petroleum fat.

[0015] Further, the lubricating additive is selected from one or a mixture of at least two of trimethylolpropane trimethacrylate, trimethylolpropane trioleate, 2-ethyl-2-nonanoyloxymethyl-1,3-propanediol dinonanoate, ethoxylated trimethylolpropane triacrylate, trimethylphosphonoacetate, trimethylolpropane tris(3-mercaptopropionate), glycerol oleate, methyl cis-9-octadecenoate, pentaerythritol oleate or tetra-polymerized ricinoleic acid ester.

[0016] The preparation method of the above-mentioned wear-resistant lubricating rust-proof oil comprises the following steps:

[0017] (1) According to the above weight parts, add the sulfonate rust inhibitor and the film-forming agent into the mineral oil, heat and stir to obtain a mixture.

[0018] (2) Cool the mixture obtained in step (1) to 30-40 °C, then add the oil solvent, organic acid rust inhibitor, hydrocarbon base oil and lubricating additive, stir and mix evenly, and finally filter to obtain the wear-resistant lubricating rust-proof oil.

[0019] Further, in step (1), the temperature of the heating and stirring is 90 - 120 °C, the rotation speed is 300 - 500 rpm, and the time is 30 min - 60 min.

[0020] Further, in step (2), the rotation speed of the stirring is 300 - 500 rpm, and the time is 20 - 30 min.

[0021] Further, in step (2), the filter used for filtration is a filter screen with 500 - 1000 meshes.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1) The present invention provides a wear-resistant, lubricating and rust-proof oil, which comprises a hydrocarbon base oil, a mineral oil, a sulfonate rust inhibitor, an organic acid rust inhibitor, a film-forming agent, an oil solvent, and a lubricating additive. During preparation, first, the sulfonate rust inhibitor is compounded with the film-forming agent and the mineral oil to obtain a mixture, and then the organic acid rust inhibitor, the oil solvent, the lubricating additive, and the hydrocarbon base oil are dispersed in the mixture to prepare the rust-proof oil. In the present invention, the sulfonate rust inhibitor and the organic acid rust inhibitor are added in two steps, and the two can produce a synergistic effect. The rust-proof oil prepared has a thin oil film and a long rust-proof time, and can reduce the process requirements for the surface of the workpiece when applying the rust-proof oil.

[0024] 2) The addition of the lubricating additive in the present invention enables the rust-proof oil to have functions such as lubricating, rust-proofing, sealing, and buffering for the workpiece.

[0025] 3) The use of the film-forming agent in the present invention can increase the film-forming performance of the rust-proof oil, and improve the coating effect and leveling property of the rust-proof oil.

[0026] 4) The rust-proof oil prepared by the present invention has excellent rust-proof performance and lubricating performance, and is particularly suitable for fields with relatively high requirements for rust prevention and lubrication, such as the mechanical manufacturing field, the automotive field, the shipbuilding field, the aerospace field, the metal processing field, and so on.
