[0002] In order to reduce friction and wear, China's lubricating oil consumption reached 4.4 million tons in 2003, making it the world's second largest consumer. 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 cannot be ignored. 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 base oil. Although the requirements for the original state and performance do not seem to be high, the process is long and the cost is high, and at most it can only restore the value of the base oil. Without legal guarantees and subsidies, it is almost not economically practical. So far no one has been found that can reduce The cost of re-refining and the effective regeneration technology route for improving the quality of re-refined lubricating oil and its technology and theory. The re-refining method is to centralize all kinds of waste lubricating oil. The present invention uses classification instead of concentration, and the addition of regeneration additives instead of re-refining, the key It is the development of regenerative additives. Such regenerative additives should not only cooperate with the remaining chemical additives in waste lubricating oil to produce tribological effects, but also interact with the remaining aging by-products in waste lubricating oil to eliminate their impact on tribology. performance and other lubricating properties are adversely affected.

Embodiment 1
[0007] Embodiment 1: with triolein 40g, 103 calcium petroleum sulfonate detergents (unified code name is T103-see: China Petrochemical Products Encyclopedia P.431) 25g and 204 antioxidant anticorrosion agents (unified code name is T204- See: China Petrochemical Products Encyclopedia P.441) 35g, reacted into additive ZF at 125±2°C. According to the regenerated waste anti-wear hydraulic oil HM68, the weight of waste anti-wear hydraulic oil HM68 containing dewatered and slag is 98.5% , mixed with the additive ZF in a proportion of 1.5% by weight, and stirred at room temperature for 20 minutes, the waste anti-wear hydraulic oil HM68 can be regenerated.
[0008] After regeneration, the tribological function is restored, and it is also significantly better than the original new oil: for the steel / steel friction pair, the friction coefficient is 32.88% lower than the original new oil, the wear is 15.5% lower than the original new oil, and the bearing capacity (PB) is lower than that o...

The invention relates to additive ZF which is prepared from 35 to 45g of glycerin trioleate, 21 to 29g of 103 calcium petroleum sulfonate detergent and 32 to 38g of 204 anti-oxidation and anti-corrosion agent which react at 120 to 130 DEG C. The tribology functions of the recyclable oil 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 an additive ZF.
