Compared with the prior art, the ether-ester type synthetic gear oil provided by the invention has good viscosity-temperature performance, low temperature performance and extreme-pressure abrasion resistance at the same time. The ether-ester type synthetic gear oil provided by the invention is particularly suitable for lubricating gears.
Description
Technical field
The present invention relates to a kind of ether-ester type synthetic gear oil, belong to the lubricating oil field.
Background technology
Gear oil also becomes gear grease, is widely used in the various gear movement processes.Gear oil has following several basic requirement.
1. suitable viscosity and good sticking warm nature
Suitable gear oil viscosity can guarantee under the elastic hydrodynamic lubrication state, forms enough thick oil film, makes gear have enough supporting capacitys.But oil viscosity can not be too high, otherwise can make rupture of oil film because of internal friction of liquids heat is excessive.Good sticking warm nature can still keep enough oil-bound films, the unlikely wearing and tearing under the gear tooth friction hot conditions.Have enough flowabilities when low temperature, there are enough gear oils flank of tooth lubricant housings, prevents to start wearing and tearing.
2. enough extreme pressure anti-wears
This is the most important performance of gear oil.Gear oil should form border adsorption film or chemical reaction film rapidly under high speed, low speed, heavy duty or impact load, prevent breakoff phenomenons such as the flank of tooth weares and teares, scratch, gummed, makes wheelwork be able to long-time running.
3. need good low-temperature performance
Have enough flowabilities when low temperature, there are enough gear oils flank of tooth lubricant housings, prevents to start wearing and tearing.
Except that this salient features requires, go back some performance requriementss, for example, when good oxidative stability and heat-resistant quality, gear oil are turned round, accelerate the oxidation of oil easily under comparatively high temps, can make the quality deterioration of oil, influence the flowability of oil and cause corrosion of metal and corrosion.Now more and more higher to the requirement of gear oil thermal oxidation stability.Good corrosion-resisting resisting resistance, gear oil in use, owing to the effect of oxidation and additive makes flank of tooth corrosion; In the presence that water and oxygen are arranged, the flank of tooth and wheel casing can get rusty.Corrosion and corrosion meeting destroy the morphology of tooth, destroy normal lubricating status.Therefore, gear oil should have good antirust and non-corrosibility.
In existing gear oil, or viscosity temperature characteristic is preferably arranged, or good low-temperature performance is arranged, or good extreme pressure anti-wear is arranged, also do not have a kind of gear oil can have good viscosity temperature characteristic, low-temperature performance and extreme pressure anti-wear simultaneously.

More preferably, described defoamer is silicone based defoamer.
Ether-ester type synthetic gear oil provided by the present invention compared with prior art can have good viscosity temperature characteristic, low-temperature performance and extreme pressure anti-wear simultaneously.
Ether-ester type synthetic gear oil provided by the present invention is specially adapted to the lubricated of gear.
Embodiment
For those skilled in the art can understand technical scheme provided by the present invention better, further set forth below in conjunction with specific embodiment.
Ether-ester type synthetic gear oil provided by the present invention adopts conventional preparation method promptly can obtain.At a certain temperature, required component is placed on to mix in the container successively and gets final product.For example: polyoxyethylene poly-oxygen propylene aether is heated to about 60 ℃, successively other components is added and stir.
Embodiment 1～5
Polyoxyethylene poly-oxygen propylene aether is heated to about 60 ℃, successively other components is added and stir.The prescription of embodiment 1～4 is as shown in table 1.
Table 1
Table 1 (continuing)
Embodiment 6～12
Ether-ester type synthetic gear oil and MobilgearSHC320 synthetic gear oil in the market, GB CKD320 type gear oil with embodiment 1～5 preparation compare test, and test-results is as follows.Need to prove that Mobilgear SHC320 synthetic gear oil is more representational polyolefin-type synthetic gear oil, be called for short the 6# gear oil; GB CKD320 type gear oil is the index of the national standard quoted, abbreviates the 7# gear oil as.
(1) viscosity temperature characteristic
Viscosity temperature characteristic can be represented the temperature variant degree of oil product, and (VI) represents with viscosity index, and viscosity index is high more, and the expression oil viscosity is more little with Temperature Influence, and its viscosity temperature characteristic is good more, otherwise then poor more.
See also table 2.Table 2 is a viscosity index performance synopsis.
Table 2
| The oil product title | Viscosity index |
| Embodiment 1 | 208 |
| Embodiment 2 | 220 |
| Embodiment 3 | 221 |
| Embodiment 4 | 212 |
| Embodiment 5 | 215 |
| 6# | 155 |
| 7# | 90 |
As can be seen from Table 2, the viscosity index of the ether-ester type synthetic gear oil of embodiment 1～5 preparation illustrates that apparently higher than 6# and 7# gear oil its viscosity temperature characteristic has obtained bigger lifting.
Good temperature tolerance can make ether-ester type synthetic gear oil also can keep good oil film strength under the condition of high temperature, reduces the wearing and tearing of gear surface, prolongs service life of gear.
(2) low-temperature performance
A kind of very important index of low-temperature performance is a pour point.Oil product can solidify at low temperatures.Oil product is being cooled to and can not flowing, but flowable again this critical temperature point of an intensification is " pour point ".Pour point is low more, represents that the low-temperature performance of this oil product is good more.Pour point is low, shows at low temperatures, and the still old good flowability of oil product so, just can be used under low temperature environment, and especially the north cold area of China also can start at low temperatures well, and is little to the impact of equipment, saves the energy.
See also table 3.Table 3 is the pour point synopsis.
Table 3
| The oil product title | Pour point (℃) |
| Embodiment 1 | -43 |
| Embodiment 2 | -42 |
| Embodiment 3 | -44 |
| Embodiment 4 | -42 |
| Embodiment 5 | -43 |
| 6# | -33 |
| 7# | -8 |
As can be seen from Table 3, the pour point of the ether-ester type synthetic gear oil of embodiment 1～5 preparation is starkly lower than 6# and 7# gear oil, and low-temperature performance is better than 6# and 7# gear oil.
(3) extreme pressure anti-wear
Extreme pressure anti-wear has been represented the lubricity of gear oil, uses last non seizure load (PB value) to characterize usually.The PB value is high more, represents the supporting capacity of gear strong more, and is little to the wearing and tearing of gear.
See also table 4.Table 4 is the synopsis of PB value.
Table 4
| The oil product title | PB value (N (newton)) |
| Embodiment 1 | 1498 |
| Embodiment 2 | 1568 |
| Embodiment 3 | 1524 |
| Embodiment 4 | 1505 |
| Embodiment 5 | 1517 |
| 6# | -33 |
| 7# | -8 |
As can be seen from Table 4, the PB value of the ether-ester type synthetic gear oil of embodiment 1～5 preparation obviously is better than other oil products, and stronger supporting capacity is arranged.
In summary it can be seen that ether-ester type synthetic gear oil provided by the present invention can have excellent viscosity temperature characteristic, low-temperature performance and extruding wear resistance simultaneously, the scope of application is more extensive.
Ether-ester type synthetic gear oil provided by the present invention compared with prior art can have good viscosity temperature characteristic, low-temperature performance and extreme pressure anti-wear simultaneously.
Ether-ester type synthetic gear oil provided by the present invention is specially adapted to the lubricated of gear.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
