Abstract
The present invention has opened up the purposes of 13,14 pairs of hydroxyl behenic acids as additive for wear resistance of lubricating oil.The wear-resistant type lubrication anti-wear agent of the friction polymer that does not the contain wear-resistant element excellent property of this novelty is used economical.Because it does not contain wear-resistant elements such as sulphur, phosphorus, zinc, should not use so go for traditional sulphur zinc phosphate type (ZDTP type) additive for wear resistance of lubricating oil yet, does not allow to contain the lubricated occasion of metallic elements such as sulphur, phosphorus, chlorine, nitrogen or zinc.
Description
The present invention is with the purposes invention of 13,14 pairs of hydroxyl behenic acids as additive for wear resistance of lubricating oil.
Present 13,14 pairs of hydroxyl behenic acids are only as reagent, do not see that as yet document introduces the purposes on its industry, do not see more that document has to utilize the record of 13,14 pairs of hydroxyl behenic acids as the lubricating oil product additive.
It is a principal object of the present invention to 13,14 pairs of hydroxyl behenic acids are used as high performance additive for wear resistance of lubricating oil.
Some wear preventive additives in the past rely on wear-resistant element (as sulphur, phosphorus, nitrogen, chlorine, zinc, molybdenum etc.) to form chemical films on surface of friction and play wear-resistant effect.Yet the sour anti-wear agent of 13,14 couples of hydroxyl mountain Yu of the present invention does not contain any wear-resistant element, and generation friction polymer own sticks to and played the anti-attrition effect on the surface of friction when finding to be the dependence friction through testing, and this is the wear preventive additive that a kind of new development is got up.Can be applicable to contain the lubricated occasion of metallic elements such as sulphur, chlorine, nitrogen, phosphorus or zinc.
Implementation of the present invention is as follows:
13, the 14 pairs of hydroxyl behenic acids are added in Metalworking lubricating oils or the industrial gear oil, ℃ stir at normal temperature to 50 at normal temperature or under 0 ℃ to 50 ℃ temperature; Best additional proportion scope by weight percentage is 0.1% to 0.3%.
For example will add the 0.2%(weight percent) N400 of 13,14 pairs of hydroxyl behenic acids
#Neutral Dormant oils and added the 1%(weight percent) N400 of dialkyl group sulphur zinc phosphate (ZDTP)
#Neutral Dormant oils, the neutral Dormant oils of 400# that does not add anti-wear agent carry out four-ball tester long term wear simultaneous test, test conditions is 294N, 30 minutes, 1450 rev/mins, test-results such as following table: the anti-wear effect that shows this agent in the table is good close with traditional anti-wear agent ZDTP.
| Base oil | The wear preventive additive title | Add weight percent | The wearing and tearing spot diameter |
| N400 #Neutral Dormant oils | 13,14 pairs of hydroxyl behenic acids | 0.2% | 0.36 millimeter |
| N400 #Neutral Dormant oils | Dialkyl group sulphur zinc phosphate | 1% | 0.35 millimeter |
| N400 #Neutral Dormant oils | Do not have | Do not have | 0.62 millimeter |
Use has been added the N400 of 13,14 pairs of hydroxyl behenic acids
#The lubricated friction specimen surface of neutral Dormant oils carries out reflection absorption ftir spectroscopy to be measured, and measurement result shows as shown in Figure 1:
1. in two hydroxyl behenic acid hydroxyls (OH) group 3339 to 2331cm
-1The stretching vibration scope at place disappears, and shows that reaction has taken place hydroxyl groups.
2. at 1526cm
-1The circular feature peak appears in the place, shows that above-mentioned reaction has crosslinking reaction to take place,
3. at 666cm
-1(OH) basal plane outside sweep vibration peak height reduces, and showing only to have the ester group reactant to generate in the hydroxyl.
4. at 9885cm
-1(OH) basal plane outside sweep vibration disappearance, showing has polyester to form in the hydroxyl.
Other gets the two hydroxyl behenic acid polymkeric substance that aggregate into is that standard specimen carries out infrared measurement, and the gained measurement result as shown in Figure 2.The infared spectrum of comparison diagram 1 and Fig. 2, it is similar substantially to find both, but hydroxyl peak 666cm shown in Figure 1
-1Out-of-plane bending peak, place and 985cm
-1(OH) peak completely dissolve, the hydroxyl stretching vibration peak at the 1705cm place are the prominent shape of drum on the hydroxyl.Comprehensive above-mentioned every test-results can prove: the upright configuration pet reaction of guiding principle shape takes place after adding lubricating oil product in two hydroxyl behenic acids on surface of friction, thereby has formed friction polyester protective film at friction surface, has strengthened wear-resistant effect.
The above-mentioned friction surface that has a polyester protective film is carried out the red spectral analysis after with the flushing of solvent sherwood oil again, find that then infared spectrum disappears, and only stays C-H stretching vibration vestige.The friction polyester protective film that hence one can see that is produced by 22 effects of 13,14 pairs of hydroxyl mountains belongs to the physical adsorption film of character non-chemically, can utilize solvent to make it desorption.
The present invention has opened up the new purposes of 13,14 pairs of hydroxyl behenic acids as additive for wear resistance of lubricating oil, and a kind of lubrication anti-wear agent of being used for occasions such as metal processing of novelty is provided.The wear-resistant type additive for wear resistance of lubricating oil of the friction polymer excellent property of the not sulfur-bearing phosphorus of this novelty, nitrogen, chlorine, the wear-resistant element of zinc, use economy.So do not go for traditional sulphur zinc phosphate type (ZDTP type) additive for wear resistance of lubricating oil yet and should not use because it does not contain sulphur, phosphorus, zinc, chlorine, nitrogen, do not allow to contain the lubricated environment of metallic elements such as sulphur, phosphorus, chlorine, nitrogen, zinc.
Claims (2)
1,13,14 pairs of hydroxyl behenic acids are as additive for wear resistance of lubricating oil.
2, the using method of 13,14 pairs of hydroxyl behenic acid wear preventive additives is characterized in that by weight percentage 13,14 pairs of hydroxyls 22 of 0.1% to 0.3% are added in Metalworking lubricating oils and the gear oil and stirs.
