Embodiment 1

[0020] Embodiment 1, the high-grade fully synthetic engine oil raw materials include 55 to 70 parts of poly-olefins, 20 to 25 parts of alkylnaphthalene synthetic oils, 10 to 15 parts of perfluorocarbon synthetic oils, and compounded 7 to 10 parts of additives, 0.5 to 1 part of naphthenic hydrochloric acid, 0.5 to 1 part of polyammonium salt additive and 0.5 to 1 part of organic crystal cosolvent. Naphthenates can reduce engine valve melting. Polyammonium salt additives can effectively solve the cleaning problem inside the engine and reduce carbon deposits. The compound additives have anti-wear, viscosity-increasing, anti-oxidation, and anti-corrosion properties. Antifoam and other multifunctional additives.

Embodiment 2

[0021] Embodiment 2, the high-grade fully synthetic engine oil raw material comprises 55 parts or 70 parts of poly-olefins, 20 parts or 25 parts of alkylnaphthalene synthetic oils, 10 parts or 15 parts of perfluorocarbon synthetic oils, compound 7 or 10 parts of additives, 0.5 or 1 part of naphthenic hydrochloric acid, 0.5 or 1 part of polyammonium salt additive and 0.5 or 1 part of organic crystal cosolvent.

Embodiment 3

[0022] Embodiment 3, as the optimization of above-mentioned embodiment, raw material comprises poly-alkene 58.8 parts, alkylnaphthalene synthetic oil 20 parts, perfluorocarbon synthetic oil 10.8 parts, composite additive 8.8 parts, naphthenic hydrochloric acid 0.75 parts by weight parts by weight. part, 0.75 part of polyammonium salt additive and 0.5 part of organic crystal co-solvent.

Abstract

The invention relates to the technical field of lubricating oil and discloses high-grade full-synthetic steam turbine oil and a preparation method thereof. Raw material ( / b) (b) of the high-grade full-synthetic steam turbine oil comprises the following components in parts by weight: poly-a-( / b) (b) olefin, alkyl naphthalene synthetic oil, perfluorinated hydrocarbon type synthetic oil, compound additives, cycloalkyl hydrochloric acid, an multi-ammonium salt additive and an organic crystal cosolvent. The raw materials of the high-grade full-synthetic steam turbine oil provided by the invention are simple and easy to obtain, the production method is simple and easy to operate, large-batch production can be realized, the production period is short, the production efficiency can be effectively improved, and the energy consumption can be reduced; and furthermore, the reactions of the additives are more complete in comparison with the existing process, the production cost is low, the production process is safe and reliable, and the high-grade full-synthetic steam turbine oil is an environment-friendly product. Compared with the traditional production method, by adopting the preparation method provided by the invention, the cost can be saved by 23% on average for the ( / b) (b), the lubrication performance under high-temperature extreme pressure is simultaneously improved, the detergency and the dispersibility are good, the wear resistance is relatively good, the oil product has effective adhesiveness of an oil film under long-term still status, and the good lubrication effect of the oil product can be further ensured.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, and relates to a high-grade fully synthetic engine oil and a preparation method thereof. Background technique [0002] High-grade engine oil is a new type of excellent lubricating oil product. It is a kind of lubricating oil product with excellent performance made of three or more synthetic bases and compound additives. However, the existing high-grade gasoline engine oils have the following problems: 1. Very low temperature fluidity is poor, and the composition of existing mineral oil is complex, even after hydrogenation, its low temperature fluidity is not as good as synthetic oil. In the northwest, especially in the cold regions of Xinjiang, it is not suitable as a blending component of internal combustion engine oil; 2. The synthetic base oil and the mineral base oil in the raw materials of the existing high-grade engine oil have poor compatibility; 3. The synthetic base oil in th...
