Table 13 orthogonal experiments and comprehensive grading
by the comprehensive grading result in table 13 as seen, preferred plan is F-1, it is the sulfide isobutene (T321) of sulphur content 40%, the thio-ammonium phosphate (T307) of sulphur content 10% phosphorus content 8.5%, the two zinc-base basic zinc salt (T203) of the sulphur phosphorus of sulphur content 14% phosphorus content 7.5%, ditertbutylparacresol (T501), IRGANOXL135 high-temperature antioxidant (L135), dodecenylsuccinic acid (T746), the optimum addition of ethylene glycol fat (C405) is followed successively by 2.0% of mediation base oil quality, 1.0%, 0.6%, 0.2%, 0.2%, 0.1%, 0.4%.
In order to prove beneficial effect of the present invention, the contriver tests the various performances of the non-transport by road dump truck gear oil composition of the embodiment of the present invention 1 preparation, and concrete test situation is as follows:
Testing method: measure 100 ℃ of kinematic viscosities, GB/T3536 " Flash Point for Petroleum Products and determination of ignition point method (Cleveland opening agar diffusion method) " mensuration flash-point, GB/T3535 " petroleum sneeze-point assay method " mensuration pour point, GB/T12583 " lubricant extreme pressure property assay method (four ball methods) " mensuration gear oil P according to GB/T265 " petroleum products kinematic viscosity assay method "
BValue, SH/T0189 " lubrication oil antiwear damages the performance measurement method " measure wear scar diameter
The size, the GB/T7305 " oil and synthetic liquid water separable performance assay method " that measure copper corrosion rank and corroded area with frictional coefficient, GB5096 " petroleum products copper strip test method " measure the oily water separation time.
The measuring method of gear oil antioxidant property is: gear oil is heated to 160 ℃, kept 12 hours, change according to 100 ℃ of kinematic viscosities after the oxidation of GB/T265 determination of test method, and calculate the viscosity velocity of variation according to formula [(100 ℃ of kinematic viscosities of old oily 100 ℃ of kinematic viscosity fresh oils)/100 ℃ of kinematic viscosities of fresh oil] * 100%.Test-results sees Table 14.
The performance comparison test of table 14 embodiment of the present invention 1 gear oil and 85W/90GL-5 gear oil
By as seen from Table 14, the P of the non-transport by road dump truck gear oil composition of the embodiment of the present invention 1 preparation
BValue, wear scar diameter
100 ℃ of indexs such as viscosity velocity of variation, copper corrosion area and oily water separation time all are better than the 85W/90GL-5 gear oil, can be used as the gear oil that non-transport by road dump truck uses.
