Problems solved by technology

[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.

Example Embodiment

[0007] Example 1: Combine glycerol trioleate 40g, 103 calcium petroleum sulfonate detergent (unified code is T103-see: China Petrochemical Products Encyclopedia P.431) 25g and 204 antioxidant and anticorrosive agent (unified code is T204- See: China Petrochemical Products Encyclopedia P.441) 35g, reacted at 125±2℃ to become additive ZF. According to the recycled waste anti-wear hydraulic oil HM68, the weight of the waste anti-wear hydraulic oil HM68 containing dewatering and residue is 98.5% , The weight of the additive ZF is mixed at a ratio of 1.5%, and the mixture is stirred at room temperature for 20 minutes to regenerate the waste anti-wear hydraulic oil HM68.

[0008] After regeneration, the tribological function is restored, and it is also significantly better than the original new oil: the friction coefficient of the steel / steel friction pair is reduced by 32.88% compared with the original new oil, the wear is reduced by 15.5% compared with the original new oil, and the be...

Abstract

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. Background technique [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. With...
