Base oil is HVIS150, and 40 ℃ kinematic viscosity is 28-32mm
2The neutral paraffin base mineral oil of/s.
Rare-earth additive of lubricating oil its preparation method of the present invention is as follows: by the parts by weight of component, phosphoric acid ester of the water-solubility rare-earth compound of 10-15 part is soluble in water and 8-15 part and the mixing diluents of 15-30 part, in blending Fu, stir, be warmed to 45 ℃-80 ℃, stir the oxyhydroxide that adds 6-12 part after 2-4 hour, continue to stir 4-6 hour, after its naturally cooling is separated, remove material such as anhydrate, again with the organic amine of 25-35 part, the base oil of the detergent-dispersant additive of 15-20 part and 30-50 part joins successively in the above-mentioned solution and mixes, heat 40 ℃-65 ℃, stir and got final product in 1-2 hour.
Rare earth slip additive of the present invention compared with prior art has superior characteristics: have good peace and quiet dispersion, extreme-pressure anti-wear, low pollutant performance in lubricating grease, addition is 0.1-5% (weight) during as lubricating oil additive.
With four-ball friction and wear test machine extreme pressure and the abrasion resistance of rare earth slip additive in paraffin oil, machinery oil, SF-CC oil estimated.Extreme pressure property is to carry out according to GB3142-82.The operational condition of wear-resistant experiment is: temperature: 25 ℃; Time 30min; Rotating speed 1450YPM; Load 392N after experiment finishes, measures the wear scar diameter (mm) of steel ball, and the result lists table 1 in.
Table 1: extreme pressure (PB value) and abrasion resistance evaluation result
Annotate: rare-earth additive of lubricating oil is represented with LB.
According to test-results as can be seen, rare-earth additive of lubricating oil has good extreme pressure property and wear resistance as sliding oil additive, is a kind of lubricating oil that has wide application prospects, fat extreme-pressure anti-friction additive.
In order to understand the present invention better, now the invention will be further described by embodiment.
