Description
Technical field
The present invention relates to a kind of breaker compositions, more particularly to are suitable for the breaker composition of lubricating oil.
Background technology
Steam turbine oil, industrial gear oil, maritime applications system lubricating oil etc. have been frequently run onto field existing for water in use
It closing, these lubricating oil are easy to form the emulsification system of Water-In-Oil with water, especially when containing additive with surface-active,
Emulsification of lubricating oils situation is more serious.If water-oil separating cannot be realized in time, it will deteriorate oil lubrication situation, less serious case
The formation of oil film can be influenced, lubricating ability is reduced, severe one can cause the corrosion and abrasion of machinery, or even damage equipment, influence to give birth to
Production and safety.Therefore, the demulsification resistance of lubricating oil is an important physical and chemical index.
Lubricating oil breaking method mainly has chemical demulsification method, physical demulsification method, biological demulsifying method, joint demulsification method, film broken
Newborn method etc..Wherein, addition demulsifying agent makes the chemical demulsification method of the grease quick separating of lubricating oil, need not additionally increase and set
It is standby, both facilitated, is simple, is economical, while generally having no adverse effects to the physicochemical property of oil product, and being a kind of method of first choice.Therefore
Development for demulsifier, there are many research reports.
US 2979528 describes nitrogenous Pluronic F-127, propylene oxide composition detersive, wherein to be no more than 6
The nitrogenous compound of carbon atom is starting reaction raw materials, these nitrogenous compounds can be ammonia, secondary amine, alkenyl polyamine, hydramine, piperazine
Piperazine, alkyl-substituted piperazine, ammonium hydroxide, phenol amine, wherein oxygen propyl group chain are connected with the atom for connecting reactive hydrogen, oxyethylene chain and oxygen third
Alkenyl chain end connects.The average molecular weight of oxygen propyl group chain is 900~25000, and oxyethylene chain accounts for the 20%~90% of compound,
Compound with the above structure has preferable detergency.
The study found that various demulsifiers, which are applied in combination, reaches preferable demulsification, such as：CN 1013502B are described
A kind of anti-emulsifying compound additive for lubricant is the four poly- trimethylene derivative of alkylene diamine by average molecular weight 2000~10000
With selected from C10~C20Alkenyl succinic acid, C10~C36Carboxylic acid dimerization, C10~C22One kind of saturated or unsaturated aliphatic acid has
Machine carboxylic acid composition forms.The anti-emulsifying compound agent is used as the lubricating oil component including steam turbine oil, gear oil, hydraulic oil,
Its demulsification performance and rustless property can be effectively improved.
CN 101721841 describes a kind of lubrication oil composite type demulsifier, is made of anti-foaming agent, demulsifier and solvent, with
Composite demulsifying agent total weight is 100% meter, and anti-foaming agent mass percent is 0.5%~15%, and demulsifier mass percent is
1%~25%, solvent quality percentage is 60%~98%, wherein described anti-foaming agent is silicone oil, fluorine containing silicone oil and acrylic acid
One or more in ester copolymer, demulsifier is polyethers demulsifier.
Although the demulsifier of the above patent introduction can be used for lubricating oil demulsification, there are still demulsification is effective
Fruit is bad, the problem of needing that more demulsifier is added.In addition, some demulsifiers, especially polyethers demulsifier is due to containing
Hydrophilic radical and be easy separated with oil phase, not only cause the production cost of lubricating oil to rise, at the same also be not easy guarantee lubricating oil
Quality.Therefore, existing lubricating oil demulsifier still has limitation, requires further improvement.
