Embodiment 1

[0007] A low-temperature-resistant lubricating oil formula, the raw materials in the formula are composed by weight percentage: base oil 5%, lubricating oil additive 1%, graphite 1%, bentonite 5%, coupling agent 3%, nonylphenol polyoxygen Vinyl ether 2%, hexachlorocyclopentadiene 1%, ethanedithiol 11%, propolis extract 5%, seaweed extract 3%, graphene 3%, modified zircon powder 1%, methyl carbamate 5%, 1% benzimidazole, 4% potassium dihydrogen phosphate, and 2% composite ashless dispersant. At this time, the low temperature performance of low temperature resistant lubricating oil is insufficient.

Embodiment 2

[0009] A low-temperature-resistant lubricating oil formula, the raw materials in the formula are composed by weight percentage: 15% base oil, 5% lubricating oil additive, 10% graphite, 15% bentonite, 9% coupling agent, nonylphenol polyoxygen Vinyl ether 3%, hexachlorocyclopentadiene 5%, ethanedithiol 19%, propolis extract 7%, seaweed extract 5%, graphene 5%, modified zircon powder 5%, methyl carbamate 10%, 1.5% benzimidazole, 5% potassium dihydrogen phosphate, and 4% composite ashless dispersant. At this time, the low-temperature resistant lubricating oil has insufficient low-temperature resistance.

Embodiment 3

[0011] A low-temperature-resistant lubricating oil formula, the raw materials in the formula are composed by weight percentage: 10% base oil, 3% lubricating oil additive, 6% graphite, 10% bentonite, 6% coupling agent, nonylphenol polyoxygen Vinyl ether 2.3%, hexachlorocyclopentadiene 1.5%, ethanedithiol 11.9%, propolis extract 5.7%, seaweed extract 3.5%, graphene 3.5%, modified zircon powder 1.5%, methyl carbamate 8%, benzimidazole 1.28%, potassium dihydrogen phosphate 4.5%, and composite ashless dispersant 2.4%.

Abstract

The invention discloses a low-temperature-resistant lubricating oil formula. Raw materials in the formula comprise, in weight percent, 5-15% of base oil, 1-5% of lubricating oil additives, 1-10% of graphite, 5-15% of bentonite, 3-9% of coupling agents, 2-3% of nonylphenol polyoxyethylene ether, 1-5% of hexachlorocyclopentadiene, 11-19% of dithioglycol, 5-7% of propolis extracts, 3-5% of sea algaeextracts, 3-5% of graphene, 1-5% of modified zircon powder, 5-10% of methyl carbamate, 1-1.55 of benzimidazole, 4-5% of monopotassium phosphate and 2-4% of compound ash-free dispersing agents. Low-temperature-resistant lubricating oil has high low-temperature resistance.

Description

technical field [0001] The invention is a formulation of low temperature resistant lubricating oil. Background technique [0002] At low temperatures in existing lubricating oils, the crystals in the lubricating base oil crystallize out. Form a three-dimensional network structure and lose fluidity. In order to maintain the low-temperature fluidity of the oil, there are two ways. One is to deeply dewax the base oil to obtain lubricating oil with a low pour point, but it will damage the quality of the oil; Second, adding a small amount of pour point depressant to lubricating oil can significantly improve the shape and structure of wax crystals in the oil, thereby lowering the freezing point; generally, the alkyl side chains of pour point depressants use monomers with different carbon numbers Copolymerization, adjust the average side chain carbon number to adapt to different lubricating oil base oils, however, most of these pour point depressants use monoester or polyester wit...
