Anticorrosive oil composition that uses in a kind of metal processing and preparation method thereof
Technical field:
The present invention relates to a kind of inhibition tensio-active agent, anticorrosive oil composition that uses in particularly a kind of metal processing and preparation method thereof.
Background technology:
According to relevant medium statistics, at present, the iron and steel weight of losing because of the burn into corrosion every year is about as much as the 10-20% of metal annual production in the world.The U.S. is annual because the Direct Loss that steel corrosion causes are about 1,379 hundred million dollars, and the mechanical industry of China accounts for about 7.2% of the mechanical industry gross output value in the amount of loss aspect the corrosion, estimates annual hundred million yuan of 600-800.So, very important by the direct and indirect loss that metallic corrosion brings, caused the attention of all trades and professions, the protection against corrosion problem has become an important topic of China's metal processing industry.
At present, internal lube oil market slushing oil product category is various, but because slushing oil product technology development imbalances, mostly be the low-function slushing oil product of single agent modulation coupling, low, middle-grade slushing oil product category is more, high-grade slushing oil product category is less, and its low grade products mainly contains: sulfonate, lanolin magnesium soap, ester class, benzotriazole and derivative etc.Lanolin magnesium soap says it is the mixture of lanolin magnesium soap and unsaponifiables lanosterol from structure, has certain antirust function, but the oil soluble of lanolin magnesium soap is bad, dissolving not exclusively in oil, part lanosterol and small amount of hydroxyl groups acid soap do not dissolve and cause slushing oil opaque, turbid phenomenon is serious, time has been grown also and the layering and precipitating phenomenon can occur, influence rustless property, anti-rust-proof effect is undesirable, and oil film is too thick, influence profile, be difficult to remove, cost is higher, is difficult to satisfy cash and belongs to the requirement of processing with the slushing oil high speed development.
Summary of the invention:
The technical problem to be solved in the present invention is, overcome problems such as existing slushing oil rust-proof effect is poor, oil film is too thick, be difficult to remove, anticorrosive oil composition that uses in the metal processing thin, removing, favorable rust preventing effect easily of a kind of oil film thickness and preparation method thereof is provided, can satisfy except that the antirust function of lines of the hand inter process short term preservation, can satisfy again that the precision sizing of mantle is indoor seals the rustless property requirement for a long time up for safekeeping.
The anticorrosive oil composition that uses in the metal processing of the present invention is made of following substances according to mass percent:
Base oil: 15-20%
Sulfonated petro-leum: 37.5-52%
Polymeric carboxylic and soap class: 26-35%
Ester class: 4.5-7%
Benzotriazole and derivative: 0.2-0.5%
Get above-mentioned composition 2-17% and be diluted to 100%, can use with the 120# solvent oil.
Described base oil comprises lubricating oil 75SN or lubricating oil 150SN or lubricating oil 350SN or lubricating oil N15.
Described sulfonated petro-leum comprises barium mahogany sulfonate T701 or petroleum sodium sulfonate T702 or calcium mahogany sulfonate T101.
Described polymeric carboxylic and soap class comprise petroleum oxidate ester barium soap T743 or lanolin magnesium soap or lanolin aluminium soap.
Described ester class comprises sorbitol monooleate SP-80 or alkenyl succinic acid ester T747 or glycerol boric acid ester fatty acid ester.
Described benzotriazole and derivative thereof comprise benzotriazole T706 or tolyltriazole or ethyl benzotriazole.
The preparation method of the anticorrosive oil composition that uses in the above-mentioned metal processing is:
The base oil of 15-20% is added in the still, be warming up to 80-110 ℃, add the sulfonated petro-leum of 37.5%-52%, polymeric carboxylic and the soap class of 26-35% again, after treating its dissolving, add ester class, 0.2-0.5% benzotriazole and the derivative of 4.5-7%, stirred 2-3 hour, after the filtration, be anticorrosive oil composition of the present invention, get above-mentioned composition 2-17% and be diluted to 100%, can use with the 120# solvent oil.
The invention has the advantages that:
The present invention adopts multiple inhibiter composite synergistic to improve its rustless property, and base oil is the carrier of slushing oil recombiner, and the Van der Waals force and the antirust adsorption film of the common formation of rust-preventive agent molecule of oil molecule is provided simultaneously; Barium mahogany sulfonate T701 in the sulfonated petro-leum has excellent anti salt fog, the wet antirust function of moisture resistance, be that the soft film anti-rust oil recombiner is the indoor antirust major function agent of sealing up for safekeeping for a long time, petroleum sodium sulfonate T702 has in excellent replacement of human sweat and the moisture film and the metathetical antirust function, be to remove the antirust main antirust function agent of lines of the hand type inter process short-term, also better complex effect arranged simultaneously with other rust-preventive agent; Polymeric carboxylic and soap class are better membrane-forming agents, simultaneously, the antirust function of good resistance salt fog are arranged also; Ester class rust-preventive agent has antirust function preferably, bigger solubleness is arranged and surpass the antirust function of imitating with the compound generation of host; Though benzotriazole and derivative oil soluble are slightly poor, non-ferrous metal is had good antirust and corrosion inhibition, particularly improve rustless property to copper with cupric ion formation inner complex, also can produce the composite synergistic effect with sulfonated petro-leum; The present invention adopts multiple inhibiter compound, on rustless property, brought into play and learnt from other's strong points to offset one's weaknesses, complementary super effect compound action, its use properties and effect have produced great breakthrough, formed a kind of higher-grade, many performances composite type anti-rust oil, its rustless property will be far superior to the performance of the synthetic slushing oil of single agent, and antirust bench testing and evaluation have been passed through to optimize fully, has the wet antirust function of excellent moisture resistance, the rust prevention test data value all>720h, the 720h that is equivalent to U.S. MIL-C-standard A level, the salt fog resistance test can reach 188h, the 168h that is equivalent to Japanese 7IS-K-standard A level, and has an excellent anti-salt solution aggressiveness, water substituting, the ability of acid neutralization and sweat control, simultaneously, it is evenly thin to have film again, remove well, transparent attractive in appearance and to be in harmonious proportion technology simple, lower-cost characteristics, its rustless property can satisfy the antirust function that removes lines of the hand type of displacement of people's sweat and operation short term preservation, reach the indoor dilution type soft film anti-rust oil performance of sealing up for safekeeping for a long time of the higher metal products of working accuracy again, reached film, multiple-effect, the specification of quality of environment-friendly antirust oil composite additive.
