Description
Technical field
The invention belongs to lubricating oil field, be specifically related to a kind of cow dung lubricating oil and preparation method thereof.
Background technology
Lubricating oil is generally made up of base oil and additive two portions.Base oil is lubrication main body of oil, and determine the essential property of lubricating oil, additive then can make up and improve the deficiency of base oil aspect of performance, gives the performance that some is new, is the important component part of lubricating oil.
Lubricant base mainly divides mineral base oil and the large class of synthetic base oil two, and mineral base oil is widely used, and consumption is very large, but the product that some application scenario then must use synthetic base oil to allocate, thus make synthetic base oil be developed rapidly.
Additive is the marrow of senior lubricant in modern age, correctly selects and rationally adds, and can improve its physicochemical property, gives new property to lubricating oil, or strengthens its certain performance originally had, and meets higher requirement.According to the quality and performance of lubricating oil requirements, additive is selected meticulously, carefully balances, carry out rational allocation, it is the key ensureing quality of lubrication oil, general conventional additive has: viscosity index improver, pour point reducer, antioxidant, detergent-dispersant additive, friction negative catalyst, oiliness improver, extreme pressure agent, foam reducing composition, metal passivator, emulsifying agent, anticorrosive agent, rust-preventive agent, demulsifying agent.
Lubricating oil great majority are equipped with additive mediation and form based on petroleum fractions mineral oil, and its production will rely on non-renewable petroleum resources, and the waste oil after using is not biodegradable, contaminate environment.
At present, water-base lubricant can drip very well and solve the problem, because water-base lubricant is carrier with water, being equipped with plant prod is main lubricant, 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.Just water-base lubricant lubricity is poor, and mainly last non seizure load (PB value) is lower.
The pollution that milk cow production fecaluria dirt brings has caused the attention of government, aquaculture industry master, Pollution abatement research and planner, in succession develop different treatment technique, and establish various process engineering, mainly contain also field pattern, Natural treatment mode and industrial treatment pattern.But different tupes has different suitabilities for factors such as cultivation scale, plant's physical environment, economic conditions, how to select suitable treatment for cow manure pattern, become the key solving milk cattle cultivating and pollute.
The Chinese patent application that application number is 200610043475.4, denomination of invention is " method preparing lubricant base with vegetables oil " discloses the method preparing lubricant base with vegetables oil, first by vegetable oil methyl ester, then carry out transesterify with polyvalent alcohol, obtain that lubricant base production line is short out, output is high; But the mobility of this lubricating oil is poor, and its viscosity is not high, uses inconvenience.
The Chinese patent application that application number is 93117166.0, denomination of invention is " a kind of lubrication oil special for chain and preparation method thereof " discloses a kind of lubricating oil adopting vegetables oil, ethanol, oiling graphite, tungsten disulfide etc. to be prepared from, but the mobility of this lubricating oil is poor.
