Abstract
The invention discloses a bearing anti-corrosive oil composition, comprising the following ingredients: 81.95-98.95 wt% of lubricating oil basic oil, 1-18 wt% of sulphonate, and 0.05-5.0 wt% of imidazoline succinate. The composition has the advantages of good stability for oil-solubility, and no skinning and no sediments after long time placement, and has good anti-corrosive performance and synergism.
Description
Technical field
The present invention is a kind of antirust agent composition, specifically, is a kind of bearing anticorrosive oil composition.
Background technology
Sulfonate has two kinds of sulfonated petro-leum and synthesising sulfonates, and the former handles with the petroleum fractions sulfonation and makes, and is the byproduct that mineral oil is processed into white oil, and the latter is chemosynthesis.
Sulfonated petro-leum is to use the earliest and most popular oil-soluble antirust agent, and it can make metal avoid the chemical action of external environment or medium or electrochemical action and the corrosion that causes.It not only can be used as rust-preventive agent uses, and according to the difference of metal-salt various purposes is arranged.
Sulfonated petro-leum can be divided into neutral sulfonate, alkaline sulfonate and overbased sulfonate three classes by the difference of its metal hydroxides content; Press the difference of metal oxyhydroxide, commonly used have barium mahogany sulfonate, calcium mahogany sulfonate, a petroleum sodium sulfonate etc.
There are dinonylnaphthalene sulfonic acid salt and heavy alkylbenzene sulfonate in synthesising sulfonate China, and barium salt, sodium salt, calcium salt are arranged, and they have rust-proof effect preferably, are widely used in the slushing oil.
Sulfonate has that good moisture resistance is wet, salt fog resistance, anti-salt solution, water substituting and sour neutrality, and multiple metal is had good non-corrosibility.
According to the document introduction: relative humidity be 80% or higher humidity under, can cause the precipitation of oil soluble carboxylic soap class and aryl stearic acid calcium in the oil product and sulfonated petro-leum is partly or entirely separated from lubricating oil.Therefore, there is the molten stability problem of depositing in theory in sulfonate.
Because control conditions such as the raw material that domestic and international each factory of sulfonate is selected and synthesis technique are not quite similar, there is some difference in purity, structural performance, the shortcoming of actual commercially available sulfonate product ubiquity hydrolysis, precipitation or gel, thereby the oily molten stability of sulfonate has become the problem of worth research.
CN1415713A discloses a kind of rust inhibiting lubricant special for chain composition, comprise following component: sulfonate rust-preventive agent, alkenyl succinic acid type rust-preventive agent, dialkyl dithiophosphoric acid-formaldehyde-fatty amine condensate, the 124 Triazole fatty amine salt, the base oil of polyisobutene, Vaseline, 2,6 ditertiary butyl p cresol and surplus.Said composition has excellent rust-preventing characteristic, resistance to salt(spray)fog, water substituting, extreme pressure property, resistance to abrasion, adhesivity and easy screening characteristics, can be used for the lubricated of automobile-used chain and seals up for safekeeping antirust for a long time.
Summary of the invention
The purpose of this invention is to provide a kind of bearing anticorrosive oil composition, said composition can solve the shortcoming of the hydrolysis of sulfonate product ubiquity, precipitation or gel, and the oily molten stability of sulfonate is strengthened.
Bearing anticorrosive oil composition provided by the invention comprises each component that content is following:
Lubricant base 81.95～98.95 quality %,
Sulfonate 1～18 quality %,
Tetrahydroglyoxaline succinate 0.05～5.0 quality %.
The present composition by base oil, sulfonate, the tetrahydroglyoxaline succinate is composite forms, this composite good oily molten stability that has of evidence, can under damp and hot condition, place for a long time, solve problems such as the ubiquitous hydrolysis of commercially available sulfonate product, precipitation or gel.
Embodiment
The present invention is with divalence sulfonate and the composite use of tetrahydroglyoxaline succinate, it and base oil are mixed and made into antirust agent composition, said composition has oil-soluble group, various additives dispersed fine in oil, hydrolysis, precipitation or the gel problem of sulfonate have been solved, the molten good stability of oil is placed not skinning for a long time, is not produced precipitation, has good antirust synergism.
The present composition also can contain other rust-preventive agent except containing sulfonate, tetrahydroglyoxaline succinate, as alkenyl succinic acid or succinic diamide, described composition comprises each component of following content:
Lubricant base 81.9～98.9 quality %,
Sulfonate 1～18 quality %,
Tetrahydroglyoxaline succinate 0.05～5.0 quality %,
Alkenyl succinic acid and/or succinic diamide 0.05～3.0 quality %.
Sulfonate described in the present composition is selected from one or more the mixture in barium mahogany sulfonate, calcium mahogany sulfonate, alkaline dinonyl naphthalene sulfonate barium and the neutral dinonyl naphthalene sulfonate barium, preferred 2～15 quality % of the content of sulfonate in composition, preferred 84.9～97.9 quality % of content of lubricant base at this moment.
