Embodiment 1

[0008] With ethylene glycol oleate 54g, 1001 anti-emulsifier (the unified code is T1001-see: China Petrochemical Products Encyclopedia P.484) 23g and 203 antioxidant anticorrosion agent (the unified code is T203-see: China Petrochemical Products Daquan P.440) 23g, mixed and reacted at 115±2°C to form the regenerative additive HT, and then press the regenerated waste anti-wear hydraulic oil HM46, the weight of the waste anti-wear hydraulic oil HM46 containing dehydration and slag is 97% , mixed with a ratio of 3% by weight of the regeneration additive HT, and stirred at room temperature for 20 minutes, the waste anti-wear hydraulic oil HM46 can be regenerated, and the demulsification of the waste anti-wear hydraulic oil HM46 can be reduced from 40 minutes to 2 minutes. The tribological function has not only been restored, but also significantly better than the original new oil: the friction coefficient is 17.63% lower than the original new oil, the wear is 34.75% lower than the ...

Abstract

The invention relates to an additive HT which is prepared by mixing 48 to 60g of oleic acid glycol ester, 18 to 28g of 1001emulsion inhibitor and 18 to 28g of 203anti-oxidation and anti-corrosion and reacting at the temperature of 110 to 120 DEG C. In the recyclable waste anti-wear hydraulic oil HM46, the weight percentage of waste anti-wear hydraulic oil HM46 without water and slag is 97%, the weight percentage of the additive HT is 3%, the waste anti-wear hydraulic oil HM46 and the additive HT are mixed according to the proportions and stirred for 20 minutes at the room temperature, the demulsification time of the recyclable oil is reduced to 2 minutes, and the tribology function is recovered and significantly better than that of original novel oil.

Description

technical field [0001] The invention relates to the regeneration of waste lubricating oil, in particular to the additive of regenerated waste anti-wear hydraulic oil HM46. Background technique [0002] In order to reduce friction and wear, my country's lubricating oil consumption reached 4.4 million tons in 2003, making it the second largest consumer in the world. It is expected to reach 5.3 million tons in 2010. It is estimated that the proportion of waste lubricating oil will not be lower than 45% of its consumption. From the perspective of sustainable development and environmental protection, it must be regenerated. Since 1935, the re-refining method has been widely used at home and abroad, but it has not been recognized so far. It does not restore the original state and performance of waste lubricating oil, but only restores the original state and performance of base oil. Although its requirements seem not high, its The process is long and the cost is high, and at most...
