Embodiment 1

[0008] Take 406 oily agent (the unified code is T406-see: China Petrochemical Products Encyclopedia P.454) 20g, epichlorohydrin 40g and 204 anti-oxidant and anti-corrosion agent (the unified code is T204-see: China Petrochemical Products Encyclopedia P. 441) 40g, mixed and reacted at a temperature of 115°C to form the regeneration additive ST, then 3% of the regeneration additive ST was added to 97% of the waste gear oil 320 in which water and slag had been removed by weight percentage, and finally the After stirring for 20 minutes, the waste gear oil 320 can be regenerated, so that the copper corrosion of the waste gear oil 320 is reduced from 1826 grams to 455 grams, and the tribological function is not only restored, but also significantly better than the original new oil: two loads Compared with the original and new oil, the friction coefficient is 6.02% and 9.90% lower, the wear is 17.86% and 19.23% lower than the original and new oil, and the bearing capacity (PB) is 33.6...

Abstract

An additive ST provided in the invention is synthesized by blending 15-25g of a 406 oiliness agent, 36-44g of chloropropylene oxide and 35-45g of an oxidation and corrosion inhibitor at a temperature of 110DEG C-120DEG C. For the regenerated waste gear oil 320, 97 wt% of water and slag removed waste gear oil and 3 wt% of ST are mixed and stirred for 20min at room temperature. Consequently, coppercorrosion of the regenerated oil 320 can be reduced to 455g. With recovered tribological properties, the regenerated oil 320 is significantly superior to its original oil in terms of antifriction andwear resistance.

Description

technical field [0001] The present invention relates to the regeneration of waste lubricating oil, in particular to the additive ST of the regenerated waste gear oil 320 . 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...
