Abstract
The invention relates to an extreme-pressure antiwear additive for lubricating oil, which comprises two effective components shown in general formula (1) and general formula (2) below, wherein in the formulae, R1 is C4-18 alkyl, R2 is H or C1-12 alkyl, and R3 is C8-12 alkyl. The additive is applicable to metal processing oil, and the addition amount of the additive accounts for 0.5-3.0 wt% of lubricating oil. The additive can effectively enhance the extreme-pressure wear resistance of the lubricating oil, and has no obvious adverse effect on the annealing detergency of the oil product.
Description
Technical field:
The present invention relates to a kind of lubrication oil anti-wear extreme pressure additive.Specifically relate to a kind of extreme-pressure anti-friction additive that is applied in the metalworking fluid.
Technical background:
The quality of metal rolled oil product directly affects the surface smoothness of life-span, power consumption, draft and the metal product of roll, requires metalworking fluid to have good oilness, resistance to abrasion, cooling, annealing cleanness and oxidation stability etc.Along with operating mode is more and more harsher, the oil film strength of metalworking fluid is had higher requirement, must in oil formula, add a certain amount of extreme pressure anti-wear additives.
Extreme pressure anti-wear additives commonly used mainly is the compound of sulfur-bearing, chlorine and phosphorus isoreactivity element, sulfocompound can produce the black oil mark on the rolled products surface, contain chlorine additive corrodibility and cross strong and too high activity, all can have a strong impact on the surface smoothness after metal is processed.Phosphorus is additive owing to have the several functions such as extreme pressure, wear-resistant, antifriction, Heat stability is good concurrently, can effectively reduce additive amount, improve the productivity effect of metal working fluid, but because hyperactivity, most of additive in use can be so that the metallic surface after the processing produces spot or spot.
Patent US 20050014656 has introduced a kind of preparation method of extreme-pressure anti-friction additive, and its main ingredient is the alkyl phosphorous acid ester, and this additive has good extreme pressure and antiwear behavior and thermostability.Patent US 20030125219 has reported a kind of lubrication oil anti-wear extreme pressure additive of ring-type organo phosphorous compounds type, can be used in bearing oil, gear oil, hydraulic efficiency oil and the refrigerator wet goods prescription.Patent CN 101037638 and 101037637 provides respectively extreme-pressure anti-friction additive of a kind of phosphoramidate, phosphamide ester and preparation method thereof, and two kinds of additives may be used in the lubricating grease.
Summary of the invention:
The object of the present invention is to provide a kind of good extreme-pressure anti-wear effect that both had, simultaneously to the annealing cleanness of metalworking fluid without obvious dysgenic lubrication oil anti-wear extreme pressure additive.
Additive involved in the present invention comprises 2 kinds of compounds effective components, has respectively following structure:
R1 is the straight or branched alkyl of 4-18 carbon atom in two formulas; R2 is the alkyl of hydrogen atom or 1-12 carbon atom; R3 is the alkyl of 6-12 carbon atom.
Acid phosphorous acid ester and amine salt thereof such as general formula (1) and (2) representative, its preparation method and the application in lubricating oil, existing many-sided reported in literature, but never report the peracidity phosphorous acid ester and mix in certain proportion as extreme-pressure anti-friction additive compound use in metalworking fluid with its amine salt.
The above-mentioned lubrication oil anti-wear extreme pressure additive that contains general formula (1) and (2) 2 kinds of active principles, the content ratio of compound in additive shown in the general formula (1) is 20wt% to 60wt%, and remaining part is the compound shown in the general formula (2).
The add-on of additive of the present invention in metalworking fluid is the 0.5wt% to 3.0wt% of lubricating oil total amount, and better consumption is 1.0wt% to 2.0wt%.
In order to guarantee that above-mentioned additive has better solvability and extreme-pressure anti-wear effect in metalworking fluid, the carbonatoms of the R1 in the general formula (1) is 8-12 for well, and the R2 in the general formula (2) and R3 are 8-10 for well.
The above-mentioned additive that contains general formula (1) and (2) 2 kinds of active principles, in metalworking fluid, not only has good extreme pressure and antiwear behavior, and to the annealing cleanness of oil product without obvious detrimentally affect, be mainly used in rolled stainless steel liquid, without in stain hydraulic efficiency oil and the copper/aluminium rolling liquid.
The invention will be further described below by example.
Embodiment
Embodiment 1
The diisooctyl phosphorous acid ester is mixed as extreme-pressure anti-friction additive according to the mass ratio that is respectively 30%, 70% with diisooctyl phosphorous acid ester amino dodecane salt, adopt No. 3 industrial white oils as base oil, extreme pressure and antiwear behavior and annealing cleanness to above-mentioned additive are estimated, and the results are shown in following table:
The performance of table 1 additive in No. 3 industrial white oils
In the table 1, for estimating the metal rolling oil annealing cleanness, need to investigate its annealing foxiness grade, the method is both at home and abroad without unified standard.In order better to weigh the quality of development oil product, adopt following evaluation method in the laboratory with reference to EXXON aluminium box annealing method and in conjunction with actual applying working condition: with diameter 70mm, the aluminium box of high 20mm cleans up, get again the aluminium foil that length and width are the 50mm*50mm specification, successively be 60～90 ℃ sherwood oil with boiling range with this aluminium foil, 90～120 ℃ sherwood oil cleans 3 times, put into the aluminium box after drying, with microsyringe with the test oil droplet of 0.2ml to aluminium foil, allow oil product evenly spread out at aluminium foil surface, add a cover, the aluminium box is put into 340 ± 5 ℃ of insulations of holding furnace 1h, and the rear room temperature of naturally being down to is taken out the grading of aluminium box.According to the spot color after the annealing oil product annealing cleanness is carried out classification, totally 6 grades, specific as follows.
0 grade: have no stain
1 grade: atomic yellow stain
2 grades: slight yellow stain
3 grades: flavescence, peripheral dimmed
4 grades: obfuscation
5 grades: shade and black slag is arranged
As can be seen from Table 1, add above-mentioned additive after, base oil P
BValue can be largely increased, and the wear scar diameter of steel ball has also had obviously and reduces, and illustrates that this additive has good extreme pressure and antiwear behavior.In addition, add above-mentioned additive after, base oil is to not obviously aggravation of the corrosion of copper sheet, and shown excellent annealing cleanness, this illustrates that additive provided by the invention can not produce obvious corrosive nature to metal.
