Abstract
The invention discloses a water replacement type anti-emulsifying oil soluble corrosion inhibitor, which is mainly composed of an oxidized petrolatum barium soap, barium petroleum sulfonate, zinc naphthenate, lanolin, an anti-emulsifying agent, a cosolvent, a defoaming agent and an antioxidant, wherein the anti-emulsifying agent is ethylene glycol monobutyl ether, the cosolvent is dibutyl phthalate, the defoaming agent is polydimethylsiloxane, and the antioxidant is 2, 6-di-tert-butylphenol. The corrosion inhibitor is in the form of a dark brown oily paste, is an additive special for solvent oil, and can be fully dissolved in solvent oil by stirring at room temperature, thus forming transparent red brown water replacement type anti-emulsifying rust-preventing oil. The obtained oil has good water replacement, anti-emulsifying and antirust properties, cannot be emulsified even in the presence of alkali, and can rapidly separate the residual water on a metal surface after mechanical processing and cleaning, thus not only having an antirust effect on ferrous metal products, but also having an antirust effect on nonferrous metals and alloys. The corrosion inhibitor provided in the invention can be widely used for dehydration rust prevention during mechanical equipment and metal part processing, repairing and other processes.
Description
Technical field
The present invention relates to a kind of water displaced type emulsion resistance oil-soluble inhibitor, be the solvent oil specialist additive, form a kind of water displaced type emulsion resistance slushing oil, belong to the metal rust preventing technical field.
Background technology
The corrosion of metal problem spreads all over the national economy all trades and professions, and the corrosion of metal meeting makes the performance of metal products and commodity value receive great infringement, even can cause significant trouble and make equipment scrapping.Metal or alloy product, equipment under the effect of environment, are prone to corrode around, and wherein modal is atomospheric corrosion.This is because no matter metallic article in processing, transportation and storage process, all contacts with atmosphere unavoidably; Oxygen in the atmosphere, moisture and other impurity very easily cause the corrosion or the variable color of metal, and the most important factor that influences corrosion is airborne moisture.The method that can effectively prevent corrosion of metal has multiple, uses wherein that in base oil, to add oil-soluble inhibitor very general, because of it has the characteristics long with rust-proof life easy and simple to handle.In machinofacture and maintenance process; The metal product surface treatment is the indispensable important procedure of part, and these technologies inevitably touch the water or the aqueous solution, after part touches the water or the aqueous solution; At ditch, groove, seam, hole, bonding surface, the hand contact surface of part, park face or product than uneven surface etc.; Be easy to exist the water of trace, this part moisture is hidden inside by grease after the oiling, must cause the part corrosion.Can therefore, through adding the antirust oil film that oil-soluble inhibitor forms, replace the moisture that covers the metallic surface and stop moisture penetration to the metallic surface effectively, promptly whether have stronger water resisting property, be the essential condition that play good rust protection effect.
The present invention adopts that multiple oil-soluble inhibitor is composite to form, and utilizes the adduction effect between the inhibiter, produces synergistic effect; Form multi-level molecular adsorption film, the common space of stopping up each other makes adsorption film more complete; Moisture displacement is more thorough, and the emulsion resistance effect is more obvious, even also can emulsification under the condition that alkali exists; Remain in the moisture of metallic surface after can the sharp separation machining cleaning, thereby play better rust-proof effect with alkalescence.For part in the antirust processing of the dehydration of mechanical workout, good water-removal additive is provided.Develop water displaced type emulsion resistance oil-soluble inhibitor for this reason, have very big realistic meaning.
Summary of the invention
The purpose of this invention is to provide a kind of water displaced type emulsion resistance oil-soluble inhibitor, this inhibiter is added in the solvent oil, have good moisture displacement, emulsion resistance and rustless property.It is antirust that the present invention can be widely used in the dehydration of mechanical means and inter processes such as metallic element processing, maintenance, and it not only has good rust inhibition to the ferrous metal product, and non-ferrous metal and alloy are also had good rust inhibition.
The mass percent of water displaced type emulsion resistance oil-soluble inhibitor consists of:
Wherein non-emulsifying agent is an ethylene glycol monobutyl ether, and solubility promoter is a Witcizer 300, and skimmer is a YSR 3286, and oxidation inhibitor is 2, the 6-di-tert-butylphenol.
The preparation method of this water displaced type emulsion resistance oil-soluble inhibitor: at first oxidized petrolatum barium soap, barium mahogany sulfonate, zinc naphthenate and yolk be not higher than heat fused under 120 ℃ the condition; And then be added in the reaction kettle; Keep 90 ℃ of temperature, the limit edged stirs, and then adds non-emulsifying agent, solubility promoter, skimmer and oxidation inhibitor successively; Insulated and stirred is 2 hours in 90 ℃ reaction kettle, processes water displaced type emulsion resistance oil-soluble inhibitor.
The present invention has following major advantage:
1. this water displaced type emulsion resistance oil-soluble inhibitor is by 4 kinds of composite forming of oil-soluble inhibitor; Have synergistic effect between the inhibiter, form multi-level molecular adsorption film, the common space of stopping up each other; Make adsorption film more complete; The moisture displacement is more thorough, and the emulsion resistance effect is more obvious, thereby plays better rust-proof effect;
2. this water displaced type emulsion resistance oil-soluble inhibitor is the solvent oil specialist additive; The non-rusting solution oil that is made into not only has rustless property and also has good moisture displacement, emulsion resistance effect; Can mix with the alkali lye vigorous stirring, and all alkali lye mixtures of sharp separation;
3. the non-rusting solution oil that is made into not only has rust inhibition to the ferrous metal product, and non-ferrous metal and alloy are also had rust inhibition.
Embodiment 1: get 10 parts of this water displaced type emulsion resistance oil-soluble inhibitors, add at normal temperatures in 90 parts No. 120 solvent oils, stir inhibiter is dissolved in the oil fully, form transparent sorrel water displaced type emulsion resistance slushing oil.
Embodiment 2: get 10 parts of this water displaced type emulsion resistance oil-soluble inhibitors, add at normal temperatures in 90 parts No. 200 solvent oils, stir inhibiter is dissolved in the oil fully, form transparent sorrel water displaced type emulsion resistance slushing oil.
The technical indicator of a kind of water displaced type of the present invention emulsion resistance oil-soluble inhibitor and the foregoing description 1 and 2 water displaced type emulsion resistance slushing oil is seen shown in the table 1.
