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, copper corrosion 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 and wear resistance.
Description
Technical field
The present invention relates to the regeneration of waste lubricating oil, particularly the additive ST of regenerated gear oil 320.
Background technology
For reducing friction and wearing and tearing, China's consumption of lubricating oil reached 4,400,000 tons in 2003, was second-biggest-in-the-world country of consumption, estimated will reach 5,300,000 tons in 2010.The ratio of estimating waste lubricating oil can be lower than 45% of its consumption.From Sustainable development and environment protection meter, must be regenerated.Nineteen thirty-five rises, generally adopt purifying method more both at home and abroad, but must not approve so far, it is not virgin state and the performance of recovering waste lubricating oil, and just recovers base oil virgin state and performance, though it is not high that its requirement seems, but its process is long, and expense is high, can only recover at most the value of base oil, ensure and subsidy if can't restrain, almost without economic and practical.Not yet find so far a kind of effective regeneration technological line and technology and theory that can lower refining expense again and improve again the refining quality of lubrication oil.Purifying method is that all kinds of waste lubricating oils are focused on again.The present invention replaces concentrating with classification, replace refining again to add regenerated additive, key is the exploitation regenerated additive, this type of regenerated additive is wanted can be collaborative with remaining chemical additive in waste lubricating oil, the common tribology effect that produces, can interact with remaining aging by product in waste lubricating oil again, eliminate it to the disadvantageous effect of tribological property and other lubricities.
Gear oil 320 useless because of: copper corrosion rises to 4b, severe overweight, frictional coefficient and wearing and tearing also enlarge markedly.
Summary of the invention
For the tribology function of recovering useless gear oil 320 with overcome the copper corrosion severe overweight, the present invention proposes a kind of regenerated additive ST of regenerated gear oil 320, it is characterized in that it is by 406 oiliness improvers (unified code name is that T406-sees: Sinopec's product complete works P.454) 15-25g, epoxy chloropropane 36-44g and 204 oxidation and corrosion inhibitors (unified code name is that T204-sees: Sinopec's product complete works P.441) 35-45g, hybrid reaction forms at 110 ℃ of-120 ℃ of temperature.Press in regenerated gear oil 320, contain and anhydrate and the weight of the useless gear oil 320 of slag is 97%, the weight that contains regenerated additive ST is that 3% ratio is mixed, and then at room temperature it is stirred 20min, can make useless gear oil 320 obtain regeneration.
The copper corrosion of the useless gear oil 320 after regeneration is down to 455 grams by 1826 grams, its tribological property has not only obtained recovery, and its anti-friction wear-resistant and bearing function all significantly be better than its former fresh oil, thereby broken through first that countries in the world so far are that generally adopt, the performance of base oil that can only recover waste lubricating oil and in the situation that the regeneration usefulness of the purifying method again of the best value that can only recover base oil.Simultaneously, also broken through and invested in integrated mill, adopt the mode of large-scale regeneration specific equipment regenerated lubricating oil, because the process with regenerated additive regenerated lubricating oil is very simple, both need not large-scale specific equipment, non-environmental-pollution, thereby user again is regenerated lubricating oil voluntarily, thus can be directly a large amount of reuse waste lubricating oils and cutting down expenses.
Embodiment
Following examples are in order to illustrating the present invention, but the invention is not restricted to following examples.
Embodiment 1
with 406 oiliness improvers (unified code name is that T406-sees: Sinopec's product complete works P.454) 20g, epoxy chloropropane 40g and 204 oxidation and corrosion inhibitors (unified code name is that T204-sees: Sinopec's product complete works P.441) 40g, hybrid reaction forms regenerated additive ST at 115 ℃ of temperature, then by weight percentage 3% regenerated additive ST is joined 97% dewater and the useless gear oil 320 of slag in, at room temperature it is stirred 20min at last, can make useless gear oil 320 obtain regeneration, thereby make the copper corrosion of useless gear oil 320 be down to 455 grams by 1826 grams, the tribology function has not only obtained recovery, and significantly be better than former fresh oil: the frictional coefficient under two load has reduced by 6.02% and 9.90% than former fresh oil, wearing and tearing have reduced 17.86% and 19.23% than former fresh oil, supporting capacity (PB) has improved 33.64% than former fresh oil and (has seen fresh oil for details, waste oil, the tribological property table of recovered oil).
The tribological property of fresh oil, waste oil, recovered oil relatively
Annotate: waste oil has dewatered and slag
