Abstract

The invention discloses a kind of pure cation cold rolling of strip steel oil, it is made up of polyester, cationic surfactant, extreme pressure anti-wear additives, cleaning additive, antirust agent, antioxidant, vegetable oil.The present invention has the characteristics of high lubrication, high detergency and low oil consumption.

Description

Pure cation cold rolling of strip steel oil
Technical field
The present invention relates to a kind of cold rolling of strip steel oil.
Background technology
Cold-strip steel has many uses, such as automobile making, electric equipment products, rolling stock, aviation, precision instrument, canned food It is, by carbon structural steel hot rolled strip, the steel plate that thickness is less than 4mm to be made by further cold rolling Deng it.In cold rolling of strip steel In technical process, strip self-deformation amount is very big and severe friction produces amount of heat and iron powder between roll and strip, So technological lubrication must be used during cold rolling of strip steel.Cold rolling of strip steel ROLLING OIL plays very important work in cold-rolled process With, can lube plate band and roll, reduce frictional force, prevent that roll and strip from bonding because frictional force is excessive, while emulsion The amount of heat produced in strip plastic deformation and friction process can also be taken away, roller surface temperature is reduced, improving roll makes With the life-span, emulsion also has cleaning and anti-rust action concurrently in addition.
ROLLING OIL used by country's cold rolling of strip steel process is mainly nonionic type ROLLING OIL and compound ROLLING OIL at present(Sun Ion and nonionic compounding).Nonionic type ROLLING OIL on-site maintenance is more convenient, because nonionic emulsifier is difficult by other Ion interference, emulsion granularity and stability can maintain normal range (NR) well, so nonionic ROLLING OIL was rolled Journey is more stable.But because it is poor to operation of rolling iron powder dispersibility, easily cause a large amount of iron powders to be assembled, cause live breast Change liquid oil slick excessive, and then make it that rolling the residual iron of rear belt steel surface Residual oil rises, plate face reflectivity declines, so nonionic in recent years ROLLING OIL is gradually substituted by compound ROLLING OIL.The type ROLLING OIL has one really to reduction oil consumption, improvement pan cleanliness It is fixed to improve, but the fluctuation of the index such as the granularity of emulsion, pH value, stability is larger in actual application, and on-site maintenance is stranded Hardly possible is, it is necessary to which often extra add function additive to maintain emulsion performance in normal range (NR), and this has a strong impact on normal Rolling Production. The problem of this product during domestic nonionic and compound cold-rolled lubricating oil use at present for existing, and according to the big pressure of Modern High-Speed Lower rate cold-rolling process requires feature, by selecting high-performance aliphatic amine cation surfactant, then compounds lubricity and degraded Property fabulous synthetic ester, vegetable oil, extreme pressure anti-wear additives, dispersant, antirust agent etc., obtain a kind of high-performance cation cold rolling of strip steel Oil.The oily concentration of cold rolling of strip steel used in the market is general in 2-3%, and the oil consumption of ton steel is in 0.5 kg/tonne of steel, more liquid week Phase is 6-12 months.This Project Product is because with excellent lubricity and iron powder dispersiveness, so concentration can be reduced to 1-2%, ton steel oil consumption can be reduced to below 0.2 kg/tonne of steel.
The content of the invention
It is an object of the invention to provide a kind of high lubrication, high detergency and the pure cation cold rolling of strip steel of low oil consumption Oil.
The present invention technical solution be:
A kind of pure cation cold rolling of strip steel oil, it is characterized in that:It is made up of the composition of following weight percents:
Polyester ... ... ... ... ... .. ... ... .5~20%
Cationic surfactant ... ... ... ... ... .0.5~2%
Extreme pressure anti-wear additives ... ... ... ... ... ... .3~5%
Cleaning additive ... ... ... ... ... ... ... .1~2%
Antirust agent ... ... ... ... ... ... ... .0.5~2%
Antioxidant ... ... ... ... ... ... ... .0.5~1%
Vegetable oil ... ... ... ... ... ... ... surpluses.
Polyester is high molecular polymerization ester, tricarboxymethyl propane oleate, trimethylolpropane palmitate, trihydroxy methyl Propane cocinin, PETO, pentaerythrite palmitate, one kind in pentaerythrite cocinin or several Kind.
Cationic surfactant is imidazoline quaternary ammonium salt, dodecyl sulfobetaine, coco amine APEO, ten In eight zephirans, cetalkonium chloride, dodecyl benzyl dimethyl ammonium chloride It is one or more of.
During extreme pressure anti-wear additives are ZDDP, olefine sulfide, sulfide aliphatic acid ester, sulfurized lard, sulfuration cottonseed oil, phosphate It is one or more of.
Cleaning additive is polyoxyethylene polyoxypropylene block polyether, EO/PO fatty amines block polyether, aliphatic alcohol polyethenoxy (5-20)Ether, NPE, ox alcohol APEO, Si Ben -80, glycerin polyoxyethylene ether, polyethylene glycol oleic acid One or more in ester.
Antirust agent be aliphatic acid, alkenyl succinic acid ester, alkylsulfonate, amine, acid amides boric acid MEA, sulfonic acid ammonia salt, One or more in borate, oleic acid.
Antioxidant refers to one in DBPC 2,6 ditertiary butyl p cresol, butylated hydroxyarisol, tert-butylhydroquinone Plant or several.
Vegetable oil is the one or more in palm oil, rapeseed oil, soybean oil, coconut oil.
Advantages of the present invention:
1. formula constituent selects the vegetable oil and synthetic ester of excellent lubricating properties, then compounds special extreme pressure anti-wear additives, increasing Stick and surfactant, obtain a kind of excellent ROLLING OIL of lubricity.Tested through laboratory four ball method:PB values(Four ball method) >=2078N, PD value(Four ball method)≥9000N.
2. formula constituent is using compatible good, dodecyl sulfobetaine and cocounut oil with special molecular structure Amine APEO (coco amine carbon chain lengths are the mixed amine that C12 and C14 is constituted according to special ratios) compounding does cation form Face activating agent.The type cationic surfactant after compounding has more preferable emulsification than commercially available common cationic surfactant Ability, iron powder dispersibility and cleansing power;In addition to improve product cleansing power, improve belt steel surface cleannes, formula is adopted Main cleaning additive is done with novel cation EO/PO fatty amine block polyethers.As a result of this unique cation form Face activating agent compounded technology, product iron powder dispersibility exceptional, and surface oil slick process in actual use Stirring and nozzle shearing are easy to emulsify again, therefore very high with the belt steel surface reflectivity after product rolling, consume very low. The plate face reflectivity that the product passes through after being rolled under client's field experiment in one month, equal conditions is substantially improved by original 62% To 83%, and the oil consumption of ton steel is also reduced to 0.19 kg/tonne of steel by 0.54 kg/tonne of original steel.
3. formula does main emollient component from the fabulous vegetable oil of biological degradability and synthetic ester, without mineral oil, again The poisonous and harmful substances such as metal, aromatic hydrocarbon, BOD(Biochemical oxygen demand (BOD))/COD(COD)>=0.65, the biochemical place of waste liquid Reason ability is strong, and environmental pollution is small, friendly to human and environment.
With reference to embodiment, the invention will be further described.
