Description

Multifunctional lubricating additive

Technical field

The present invention relates to the oil dope technical field, is a kind of multifunctional lubricating additive specifically.

Background technology

Because gear oil is different with the performance requriements of worm and worm wheel oil, therefore gear oil and worm and worm wheel oil are not general at present; And at some factory's middle gears and the shared fuel tank of worm and gear; And the additive that vulcanizes sulfur-bearings such as rare hydrocarbon or atmosphere in the gear oil approximately has the deep-etching effect to copper; At present mainly to press additive with sulphur or chlorine power be main on the market gear oil, and worm and worm wheel oil is main with oiliness improver then, thus gear grease one be not suitable for the lubricated of worm and gear.Industrial gear oil's recombiner is the recombiner that is used to modulate the medium duty industrial gear oil of the various viscosity trades mark, and it adds dosage is to weigh one of this recombiner level, the most important index of Technological Economy property.Through domestic and international patent inquiry; The publication and the data of associated viscera found to have in the end; And domestic documents and materials introduction; The medium duty industrial gear oil recombiner of enlightening minister company is liked in Nanjing, and adding dosage is 1.4% (quality), but all not by the concrete public reported of forming to the medium duty industrial gear oil recombiner.The objective of the invention is: a kind of middle load additive composite of lubricating oil for industrial gears is provided; Applicable to various base oils, all satisfy the specification index of GB 5903-95 with the medium duty industrial gear oil of its each viscosity trade mark such as synthetic 100,220,320,460,680.Like number of patent application is 00126560.1; The applying date: 2000-09-23; Patent name is the patent of invention of " composite additive of lubricating oil for industrial gear turbine ", and its technical scheme discloses a kind of gear-worm gear that is used for composite additive of lubricating oil and preparation method thereof.It is made up of extreme pressure anti-wear additives, oiliness improver, rust-preventive agent, non-emulsifying agent, corrosion inhibitor basically.The lubricating oil of this compositions of additives preparation satisfies the lubricated of worm and gear again when satisfying gear lubrication, with the lubricating oil of this recombiner preparation can satisfy various basic, normal, high speed with in, the enclosed gear of heavy loading and worm and gear lubricated.But above-mentioned additive can not be applicable to existing various base oil, can only work to specific gear, turbine.

Summary of the invention

The purpose of this invention is to provide a kind of can satisfy simultaneously gear lubrication and worm and gear lubricated and be applicable to various base oils oil dope.

The objective of the invention is to realize through following scheme:

A kind of multifunctional lubricating additive is characterized in that: comprise the following component of meter by weight:

Alkanolamine ester 1-5 part, metal passivator are mixture 5-10 part of thiadiazole verivate and 124 Triazole analog derivative for extreme pressure anti-wear additives, P-N type additive 30-40 part, sulfide isobutene 10-25 part, the multiple ester amine salt 10-20 part of sulphur phosphoric acid, oiliness improver oil oleic acid epoxy ester 50-60 part, rust-preventive agent and corrosion inhibitor oleic acid three;

Also add kilfoam and non-emulsifying agent polyethylene oxide-propylene oxide 5-15 part, pour point depressant vinyl acetate 1-5 part;

Also add metal detergent, be the organic sulfonic acid calcium salt composition, mass fraction is 10-15 part;

The ratio of said thiadiazole verivate and 124 Triazole analog derivative is 1:1.

The invention has the advantages that:

1, uses multifunctional lubricating additive of the present invention, improved the load-carrying properties of gear oil, in the life-span of having improved gear, improved the abrasion resistance of turbine.

2, in the wear resistance that improves copper, do not reduce the compressive property of gear, have good resistance to emulsion.

3, because extreme pressure anti-wear additives has added various ingredients, so industrial gear oil's recombiner of the compound multiple different size of ability.
