Problems solved by technology
The function of the additives of the current lubricating oil is generally relatively single. The anti-wear additives only have wear resistance, and the extreme pressure additives only have extreme pressure resistance. Affects the overall performance of the lubricating oil, so there is a need for a multifunctional additive that can withstand both wear and extreme pressure

A lubricating oil anti-wear extreme pressure additive is prepared from the following raw materials in parts by weight: 3-8 parts of phosphoric acid, 4-9 parts of a calcium-zinc composite stabilizer, 6-10 parts of isooctyl phosphate octadecylamine, 4-8 parts of paraffin, 5-7 parts of lupeol palmitate, 6-8 parts of dialkyl calcium benzenesulfonate, 5-7 parts of alkyl magnesium benzenesulfonate, 2-7 parts of methyl 4-hydroxybenzoate, 3-9 parts of calcium petroleum sulfonate, 6-9 parts of cobalt naphthenate, 4-7 parts of lead isooctanoate, 3-8 parts of SN-150, 6-8 parts of Twain, and 2-7 parts of Span. The lubricating oil anti-wear extreme pressure additive has the beneficial effects that the lubricating oil anti-wear extreme pressure additive can improve the overall quality of lubricating oil, particularly, can improve the anti-wear extreme pressure performance of the lubricating oil, and has less use amount.
Description
technical field [0001] The invention relates to an antiwear extreme pressure additive for lubricating oil. Background technique [0002] The operation of equipment is inseparable from lubricating oil, and lubricating oil cannot be separated from lubricating oil additives. Lubricating oil additives are the essence of various modern high-grade lubricating oils. The function of the additives of the current lubricating oil is generally relatively single. The anti-wear additives only have wear resistance, and the extreme pressure additives only have extreme pressure resistance. Affects the overall performance of the lubricating oil, so there is a need for a multifunctional additive that can withstand both wear and extreme pressure. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an anti-wear extreme pressure additive for lubricating oil, which can improve the overall qual...
