Description
Technical field
The present invention relates to slip additive technical field, particularly relate to efficient multifunctional lubricating additive.
Background technology
The fast development of modern industry, people are more and more high to the requirement of lubricating oil, the requirement to friction lubricating under the severe condition such as the quality that merely improves oil product from refining process can not meet at a high speed, highly carry, high vacuum and high low temperature.Must in lubricating oil, add quality that various additives improve oil product to meet the needs of friction pair running, and the average addition of additive also brings up to 15.9 % by 3.2 %, even higher, simple function additive has been difficult to adapt to industrial development.
Especially along with environmental problem comes into one's own day by day, people more and more pay attention to the research of environmental friendliness slip additive, the future development of forward diversification, high efficiency, multifunction, greenization.Conventional zinc dialkyl dithiophosphate (ZDDP) is the very effective multifunctional lubricating additive of a kind of modern industry, but the zinc element wherein containing easily produces galvanic corrosion, though the element such as sulphur, phosphorus is the excellent activity element of conventional lubricant extreme pressure, wear-resistant, antifriction performance, but misapplication has the defect of excessive corrosion, and environmental pollution causes detrimentally affect, especially phosphoric easily makes the poisoning of catalyst in automobile exhaust gas processing apparatus.Therefore, find and can replace " without zinc ", " without the sulphur " of ZDDP, the research of " without phosphorus " efficient multifunctional lubricating additive to become current popular research topic in recent years.
CN 102329682 A have introduced a kind of multifunctional lubricating additive, can be used for the modulation of medium duty industrial gear oil, can improve oil and extreme pressure and antiwear behavior, can improve again oily demulsification performance, but still contain a large amount of element sulphurs in additive composition; CN 1142260 C have introduced a kind of multifunctional lubricating additive, mainly that copper zinc alloy ultra-fine micropowder is distributed in oil by dispersion agent, oxidation and corrosion inhibitor and kilfoam, although testing of engine shows that it has reduced oil consumption and discharge, but solids dispersion stabilization and to oil other performance as the disadvantageous effect of detergent-dispersant performance energy, antioxidant property etc., but all the time exist; CN 1847375 A have also introduced a kind of multifunctional lubricating additive, although it can improve oily extreme pressure and antiwear behavior, in additive composition, also contain element sulphur.
Summary of the invention
The object of the invention is to propose one efficiently without sulphur phosphorus multifunctional lubricating additive, it has good extreme pressure, wear-resistant, antifriction performance, to adapt to the needs of industrial development and environment protection.
For reaching above-mentioned purpose of the present invention, the present invention proposes the reactant generating using mishmetal siccative, 124 Triazole aliphatic amide, oily potassium borate, trolamine hybrid reaction as efficient without sulphur phosphorus multifunctional lubricating additive, its temperature of reaction is 80-180 ℃, and the reaction times is 1.0-4.0 h
The present invention adopts the major constituent of mishmetal siccative as hybrid reaction, mishmetal siccative is the mixture of cerium, lanthanum, yttrium, europium carboxylic soap, its main ingredient is cerium carboxylic soap, for example cyclohexylenedinitrilotetraacetic acid soap, and can produce good synergy with boron-containing compound compound tense, improve the extreme pressure and antiwear behavior of lubricant.
The preferred 124 Triazole aliphatic amide wherein of the present invention, for example 124 Triazole stearylamine, 124 Triazole amino dodecane, as the component of hybrid reaction, it is a kind of wear-resistant friction reducer, its oiliness, erosion resistance, rust-preventing characteristic are all good, particularly, showing good synergy with boron-containing compound compound tense, can improve the extreme pressure and antiwear behavior of lubricant.
Oily potassium borate in the present invention is extreme-pressure additive, not sulfur-bearing phosphoric, and it and 124 Triazole aliphatic amide of the present invention, mishmetal siccative compound tense can produce good synergy.
The present invention adopts trolamine to create necessary hybrid reaction condition.
The proportioning of mixed reactant of the present invention is as follows:
Mishmetal siccative 15%-65%
124 Triazole aliphatic amide 15%-55%
Oily potassium borate 10%-35%
Trolamine 2%-10%
Range of reaction temperature: 80 ℃-180 ℃;
Reaction time range: 1.0h-4.0h.
Above reactive component of the present invention is all that technical grade is easily purchased product.
Above component is fully mixed in reactor, control temperature well ± 2 ℃ of scopes, carry out the reaction of corresponding time, finally obtain the oily reaction product of brown thickness, be efficient without sulphur phosphorus multifunctional lubricating additive that the present invention proposes.
The present invention proposes efficient without sulphur phosphorus multifunctional lubricating additive have good oil soluble, can be miscible with arbitrary proportion with white oil or other mineral oil, synthetic oil, its extreme pressure anti-wear is excellent especially.In addition, its environmentally harmful material of sulfur-bearing phosphorus not.The present invention is easy to operate, and exploitativeness is strong.
Embodiment
