Description
Technical field
The invention belongs to lubricating oil field is and in particular to a kind of cow dung lubricating oil and preparation method thereof.
Background technology
Lubricating oil is typically made up of base oil and additive two parts.Base oil is the main component of lubricating oil, determines the fundamental property of lubricating oil, and additive then can make up and improve the deficiency of base oil aspect of performance, gives some new performances, is the important component part of lubricating oil.
Lube base oil mainly divides mineral base oil and synthetic base oil two big class, and mineral base oil is widely used, and consumption is very big, but some application scenarios then using the product of synthetic base oil allotment, thus must make synthetic base oil be developed rapidly.
Additive is the marrow of modern age senior lubricant, and correct selection rationally adds, and can improve its physicochemical properties, and lubricating oil is given with new property, or strengthens certain performance that its original has, the higher requirement of satisfaction.Quality according to lubricating oil requirements and performance, the meticulous selection to additive, carefully balance, carry out rational allocation, be to ensure that the key of quality of lubrication oil, typically conventional additive has：Viscosity index improver, pour-point depressant, antioxidant, detergent-dispersant additive, rub moderator, oiliness improver, extreme pressure agent, foam reducing composition, matal deactivator, emulsifying agent, anticorrosive, antirust agent, demulsifying agent.
Lubricating oil great majority are equipped with additive mediation based on petroleum distillate mineral oil and form, and its production will rely on non-renewable petroleum resources, and, the waste oil after use is not biodegradable, pollutes environment.
At present, water-base lubricant can drip very well and solve the above problems, because water-base lubricant is with water as carrier, be equipped with the lubricant based on plant product, extreme pressure agent and other a small amount of auxiliary agents.Its main raw material(s) is plant resources, does not rely on non-renewable petroleum resources, is can be biodegradable, and free from environmental pollution, harmless.Simply water-base lubricant greasy property is poor, mainly maximum nonseizure load（PB value）Relatively low.
The pollution that milk cow production fecaluria dirt brings has caused government, the attention of aquaculture industry master, pollution control research and designer, in succession develop different disposal technique, and establish various process engineerings, mainly there are also field pattern, Natural treatment mode and industrial treatment pattern.But different tupes has different applicabilities for factors such as cultivation scale, plant's natural environment, economic conditions, how to select suitable treatment for cow manure pattern, become the key solving milk cattle cultivating pollution.
Application No. 200610043475.4, the Chinese patent application of invention entitled " method preparing lube base oil with vegetable oil " disclose the method preparing lube base oil with vegetable oil, first by vegetable oil methyl ester, then carry out ester exchange with polyalcohol, obtain that lube base oil production line is short out, yield is high；But the mobility of this lubricating oil is poor, and its viscosity is not high, in-convenience in use.
