Above-mentioned open type gear oil composition I, II, III, IV and V carry out performance test respectively, and testing result is as shown in table 1:
Table 1
As can be seen from Table 1, there is the open type gear oil composition I prepared by the present invention viscosity and viscosity higher to refer to Number;Open type gear oil composition I pour points can arrive -12 DEG C, of the invention in addition with good low temperature flow and pump startup Open type gear oil composition also has oxidation stability and extreme pressure and antiwear behavior higher, and viscosity build rate is low, and combination property is excellent It is different.
By embodiment 2 as can be seen that only with the addition of sulfur-bearing extreme pressure anti-wear additives when open type gear oil composition II is prepared, and Without the phosphorous extreme pressure anti-wear additives of addition, its PB value remains to reach 1186N, excellent abrasion resistance is shown, due to ester used Contain more polar ester functional groups in class artificial oil, diaphragm can be formed in friction surface, increase exposed gear oil combination The lubrication abrasion resistance of thing.
Relative to open type gear oil composition I, due in comparative example 1 using oil based on polyisobutene, it is prepared The viscosity index (VI) of open type gear oil composition III is relatively low, and viscosity temperature characteristic is poor, and pour point is higher, high temperature, the bad adaptability of low temperature, Be not suitable for the operation in the operating mode of wide temperature range change.And because polyisobutene is free of polar ester functional groups, it is not easy to Friction surface forms thick oil film, thus itself PB and PD value is relatively low, and wear scar diameter is also bigger than normal, extreme-pressure anti-wear Wear vesistance Equal deviation.In addition, the viscosity build rate of the oxidation stability of open type gear oil composition III is than open type gear oil composition I's Higher, its oxidation stability is poor.
In comparative example 2, because polyalphaolefin PAO300 and high viscosity complex ester are incompatible, obtained exposed gear oil group Compound IV muddinesses are opaque, and this also indicates that the composition that only cannot obtain having concurrently polyalphaolefin and Esters oil advantage by blending, uses Synthetic ester lubricant can avoid above inconsistent problem.
By comparative example 3 as can be seen that relative to open type gear oil composition I and II, the PB values of open type gear oil composition V Relatively low with PD values, wear scar diameter is bigger than normal, and this shows that the present invention uses synthetic ester lubricant and sulfur-bearing and/or phosphorous extreme-pressure anti-wear The compatibility of agent is good, and the synergy with extreme-pressure anti-wear can obtain the more excellent exposed gear of extreme pressure and antiwear behavior Fluid composition.
Embodiment 3
By the synthetic ester lubricant (manufacturer of 93.4 weight portions:Italmatch Chemicals, the trade mark: Ketjenlube23000, the synthetic ester lubricant is anti-by 14 alhpa olefins, 16 alhpa olefins and maleic anhydride and ethanol Product copolymerization is answered to form, its average weight-average molecular weight is 10000Da, No. CAS:173521-40-9) it is added in reactor, ties up Kettle temperature is held at 80 DEG C;Add the oleic acid of 1.5 weight portions, be stirred until homogeneous it is transparent, stop heating simultaneously kettle temperature is down to cooling water 40℃;Again successively by di-2-ethylhexylphosphine oxide (Keywords dibutyl dithiocarbamate) (manufacturer of 2.5 weight portions:The U.S. Vanderbilt Company, the trade mark:Vanlube7723), the ashless organic phospho acid amine salt (manufacturer of 2 weight portions:Bohai Sea is big Chemical Co., Ltd., the trade mark:KT139), the octyl group butyl diphenylamines of 0.5 weight portion, the benzotriazole derivative of 0.1 weight portion, plus Enter in mediation kettle, stirring to mixture is all dissolved, homogeneous transparent, obtains finished product open type gear oil composition VI.
Comparative example 4
In addition to changing the synthetic ester lubricant in embodiment 3 into high viscosity complex ester, according to side same as Example 3 Method, prepares open type gear oil composition VII.
Above-mentioned open type gear oil composition VI and VII carries out performance test respectively, and testing result is as shown in table 2:
Table 2
Be can see by table 2, the open type gear oil composition VI as prepared by synthetic ester lubricant equally glues with higher Degree index, oxidation stability and extreme pressure and antiwear behavior.Its viscosity index (VI) is up to more than 300, and viscosity temperature characteristic is very excellent, maximum nothing Seizing load PB values are up to more than 1700N, excellent combination property.
In addition, the oxidation stability and pour point of open type gear oil composition VII as prepared by high viscosity complex ester are all poor In open type gear oil composition VI, extreme pressure and antiwear behavior is also slightly less than open type gear oil composition VI, further illustrates the present invention Synthetic ester lubricant and sulfur-bearing and/or phosphorous extreme pressure anti-wear additives there is preferable compatibility.
In sum, the present invention uses synthetic ester lubricant, while adding suitable additive, it is ensured that exposed gear oil group Compound has viscosity and viscosity temperature characteristic higher, it is to avoid the situation that summer is easy to run off, winter hardly possible flows occur, and beneficial to open type tooth The formation and holding of lubricating oil film during wheel fluid composition use;Secondly, open type gear oil composition of the invention has excellent Different low temperature flowability, expands its temperature in use scope;Furthermore, open type gear oil composition of the invention in use can Bring gear pair in the low fluid friction of load area, reduce operation temperature, the raising gear of little gear and gear drive Efficiency.
In addition, from embodiment 1 and embodiment 3 as can be seen that open type gear oil composition of the invention can be prepared The exposed gear oil of different viscosities rank, the wider model of range of application.
