专利说明:

The invention relates to lubricating compositions which can be used, in particular, as oils for automobiles and tractors and contain copper in an amount sufficient
to inhibit or delay oxidation of the lubricant.
The aim of the invention is to increase the resistance of the lubricant composition to oxidation while maintaining the main

Zinc dialkyldithiophosphates, which are used in the compositions, are oil-soluble salts of dithiophosphoric acid dialkyl esters and are prepared according to a known technique by forming dithiophosphoric acid by reacting an alcohol and then neutralizing dithiophosphoric acid with an appropriate zinc compound.
Mixtures of alcohols, including mixtures of primary and secondary drains, can be used, the secondary ones being usually used to create improved anti-wear properties, while the primary ones give improved properties of temperature stability. Mixtures of these two alcohols are most applicable. Any basic or neutral zinc compound may be used, but oxides, hydroxides and carbonates are most commonly used. Industrial additives often contain an excess of zinc due to the use of an excess of the basic zinc compound in the neutralization reaction.
The ashless dispersant contained in the composition is a dispersing agent commonly used in lubricating compositions. It may be selected from the group consisting of a nitrogen-containing alkanyl succinic acid ester derivative or Mannichic base.

Such condensation products (Mannig bases) are produced by
condensation of about 1 mol of alkyl-substituted phonol.) with about 1-,
2.5 mol of formaldehyde and about 0.5-2 mol of polyalkylenepolyamine,
The nitrogen-containing alkenyl derivative of succinic acid can be obtained by the reaction of alkenyl succinic anhydride and amine. Further, this product can be modified with a boron compound, such as boron oxide, halides.
0 boron, boric acid, an alkenyl succinic acid ester can be obtained by reacting alkenyl succinic anhydride with a hydroxyl-containing compound.
5, Dispersibility can also be provided by adding a polymer dispersant that improves the viscosity index of a polymer, such as a copolymer of ethylene and propylene, a treatment with maleic anhydride and diethyltriamine, or a copolymer of ethylene and propylene, grafted to 2-vinylpyridine,
The proposed lubricant compositions
5 may contain other known additives for lubricating oils, such as additives that lower the pour point, for example, a copolymer of vinyl acetate and fumarate, as well as
0 additives that improve the viscosity index, such as a copolymer of ethylene and propylene, the composition of the concentrate can be used alkylaromatic sulfonate or magnesium phenol or
g of calcium, having a total base number (TBN) in the range of about 300-400 in an amount of 0.002-8% based on magnesium or calcium.

To this mixture is added a con-
Zinc dialkyldithiophosphate centrate (75 wt.% active ingredient in mineral oil) obtained by reaction with a mixture of about 65 wt.% isobutyl alcohol and 35 wt.% amyl alcohol, in order to ensure the phosphorus content of the lubricating oil is 0.1 wt%

To such a concentrate, the said concentrate, which improves the viscosity index, and the depressant, as well as the diluent oil, are added, as a result of which the lubricating oil composition is obtained. The concentrate is diluted 20 times to obtain the same concentrations of the active ingredient. The oxidative stability of such an oil composition is tested by oxidizing a 300 g sample of an oil composition containing 40 ppm of iron in the form of ferric acetylacetonate, passing 1.7 liters of air per minute through the sample at 165 ° C and determining the viscosity at intervals up to 64 hours. in Ferranti-Shirley viscometer. In this experiment, the composition of the oil became almost solid when a viscosity of about 5 P was reached.
The oxidative stability of the oil composition is compared with oil compositions containing known antioxidants and oil compositions containing certain copper additives.
