Abstract
The invention relates to additive LT which is prepared from 54 to 60g of triethylenetetramine, 24 to 32g of propylene oxide and 12 to 18g of 202 anti-oxidation and anti-corrosion agent which react at 120 to 130 DEG C. The acid value of recyclable oil 320 is reduced to 0.12mgKOH/g, and the tribology functions thereof are recovered and significantly better than those of original novel oil.
Description
Technical field
The present invention relates to the regeneration of waste lubricating oil, particularly a kind of additive LT of reclaiming waste oil film bearing 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. and the ratio of estimating waste lubricating oil can not be lower than 45% of its consumption.From Sustainable development and environment protection meter; the .1935 that must be regenerated rises; generally adopt purifying method more both at home and abroad; but must not approve so far; it is not virgin state and a performance of recovering waste lubricating oil; and just recover base oil virgin state and performance; though it is not high that its requirement seems; but its process is long; the expense height; can only recover the value of base oil at most; ensure and subsidy if can't restrain; almost there is not economic and practical. do not find a kind of effective regeneration technological line and the technology and theory that can lower refining expense again and improve again the refining quality of lubrication oil so far as yet. purifying method is that all kinds of waste lubricating oils are focused on again. the present invention then replaces concentrating with classification, replaces refining again to add regenerated additive, and key is the exploitation regenerated additive; this type of regenerated additive is wanted can be collaborative with remaining chemical additive in the waste lubricating oil; the common tribology effect that produces can interact with remaining aging by product in the waste lubricating oil again, eliminates its disadvantageous effect to tribological property and other lubricities.
Kelmet oil 320 useless because of: acid number rises to 0.66mgKOH/g, severe overweight, it is bigger that the tribology function reduces.
Summary of the invention
For the tribology function of recovering waste oil film bearing oil 320 with overcome the acid number severe overweight, the present invention proposes a kind of additive LT of reclaiming waste oil film bearing oil 320, it is characterized in that triethylene tetramine 54-60g, propylene oxide 24-32g and 202 oxidation and corrosion inhibitors (unified code name is that T202-sees: Sinopec's product complete works P.440) 12-18g, be reacted at 120 ℃-130 ℃. press in the reclaiming waste oil film bearing oil 320, contain and anhydrate and the weight of the waste oil film bearing oil 320 of slag is 97%, the weight that contains additive LT is 3% mixed, stirring at room 20min can make waste oil film bearing oil 320 obtain regeneration.
The acid number of the waste oil film bearing oil 320 after the regeneration is reduced to 0.12mgKOH/g by 0.66mgKOH/g, its tribology function has not only obtained recovery simultaneously, but also significantly be better than former fresh oil, so far countries in the world generally adopt thereby broken through first, can only recover waste lubricating oil base oil performance and under best situation, can only recover the regeneration usefulness of purifying method again of the value of base oil. simultaneously, also broken through and invested in integrated mill, adopt the mode of large-scale regeneration specific equipment regeneration waste lubricating oil, because the process with regenerated additive regeneration waste lubricating oil is very simple, both need not large-scale specific equipment, non-environmental-pollution again, thereby user's waste lubricating oil of can regenerating voluntarily, thereby can directly a large amount of reuse waste lubricating oils and cut down expenses.
Embodiment
Following examples but the invention is not restricted to following examples in order to explanation the present invention.
Embodiment 1.
With triethylene tetramine 57g, propylene oxide 28g and 202 oxidation and corrosion inhibitors (unified code name is that T202-sees: Sinopec's product complete works P.440) 15g, be reacted into additive LT at 125 ± 2 ℃, press then in the reclaiming waste oil film bearing oil 320, contain and anhydrate and the weight of the waste oil film bearing oil 320 of slag is 97%, the weight that contains additive LT is 3% mixed, then at stirring at room 20min, can make waste oil film bearing oil 320 obtain regeneration, the acid number of waste oil film bearing oil 320 is reduced to 0.12mgKOH/g from 0.66mgKOH/g, the tribology function has not only obtained recovery, and significantly be better than former fresh oil: frictional coefficient has reduced 9.62% than former fresh oil, and wearing and tearing have reduced 41.83% than former fresh oil, and supporting capacity (PB) has improved 86.89% than former fresh oil and (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 anhydrated and slag
Claims (2)
1. the additive LT of a reclaiming waste oil film bearing oil 320 is characterized in that triethylene tetramine 54-60g, and propylene oxide 24-32g and 202 oxidation and corrosion inhibitor 12-18g are reacted at 120 ℃-130 ℃.
2. meeting claim 1. a kind of additive LT of reclaiming waste oil film bearing oil 320 is characterized in that by in the reclaiming waste oil film bearing oil 320 contain and anhydrate and the weight of the waste oil film bearing oil 320 of slag is 97%, the weight that contains additive LT is 3% mixed.
