Description
The present invention relates to the nanometer new material technology field.
Field of nanometer material technology is the field of new that begins to develop in the 1980s.Because the ultrastructure of nano material uniqueness shows unique characteristics it, can be widely used in industrial sector and military fields such as aerospace, electronic apparatus, transportation and energy, automobile, machinery, communication, chemical industry, building materials, medicine.China in the research and development of nanometer field of new since nineteen nineties, some achievements have been obtained at present, in some famous research institutes, colleges and universities in one's power, set up research and development centre and professional production factory in succession, make nano material some Preliminary Applications arranged in above-mentioned field.But total research and development level is not as American-European developed country.Yet,, be still blank as the liquid nano magnesium compound oil-soluble material.According to the pertinent data analysis, the nano level product of research all is the material of solid powdery both at home and abroad.And all there is the difficulty of adding and disperseing in these solid matters in application, have therefore limited the application of solid nano material.
Purpose of the present invention is exactly that a kind of wide, that efficient is high, performance is good nano level magnesium compound oil-soluble material and preparation method thereof that uses will be provided.It has successfully solved in the nano-substance application adds and dispersive two big gordian techniquies.Through studying repeatedly and application test, proof the present invention is the liquid oil soluble multifunction additive of an a kind of nano level material, can be widely used in weight (slag) oil, vapour bavin kerosene, lubricating oil and the macromolecular material, to correct the performance of fuel oil structure, change oil lubrication characteristic and macromolecular material, and then realize the anticorrosion and energy-conservation of power-equipments such as engine, automobile, combustion machine, boats and ships, boiler, and efficient, the energy-conservation and environmental protection of facilities for transport and communication, fundamentally improve the economic and social benefits.
One of important technology feature of the present invention is exactly successfully to have solved nanometer to add and these two guardian technique difficult problems of dispersion, proposed in theory that the tensio-active agent parent hates the viewpoint of balance and micelle-forming concentration in the nonpolar medium, and set up the surfactant system model of unconventional content.On technology, adopt liquid phase chemical synthesis method synthesis of nano magnesium compound oil-soluble material.Below just the technical characterstic of product of the present invention elaborate.
This nanometer oil-soluble material is as the efficient component of producing nano lubricating oil; can change the lubricity of lubricating oil; at surface of friction pair the sliding friction Variable roll is rubbed; significantly reduced the friction resistance of friction pair; fundamentally protect the system of phase mutual friction; and because of its basicity height, carbon deposit is few, counteragent is strong, antirust, nontoxic, the oxygen acid that some component generates because of oxidation in the oil that can neutralize stops oil by further oxidation.Simultaneously, colloid and the carbon deposit that generates in the oil had very strong adsorptive power, paint film and carbon deposit that can will stick on the piston wash and are dispersed in the oil, are greasy dirt and plug nozzle or cylinder to prevent their coacervating large particle sedimentations.So be the basic material of making nano lubricating oil.
This nanometer oil-soluble material is as the multiple-effect purification agent of light fuels such as vapour, bavin, kerosene, have effects such as antistatic, wear-resistant, antirust, combustion-supporting, peace and quiet, can prevent that engine nozzle from stopping up, the incrustation of cylinder coking, improve the efficiency of combustion of vapour, bavin, kerosene, reduce the discharging of carbon monoxide, sulphur, oxynitride, reduce atmospheric pollution.
This nanometer oil-soluble material is as the properties-correcting agent of macromolecular material, have characteristics such as compactness is good, rate of permeation height, make an addition in the macromolecular material, can improve the performance of plastics greatly, as wear-resistant, shock resistance, antifatigue, heat-resisting, ageing-resistant and toughness, insulativity etc.Can be more obvious as effect in macromolecular materials such as transparent plastics PC, PMMA, PS.
This nanometer oil-soluble material is as the fuel oil additive in the power industries such as the dynamo-electric factory of combustion, boats and ships, boiler.Can avoid weight, residual oil when burning, to form low melting components to oil-burning apparatus generation " high temperature corrosion " because of containing heavy metal elements such as vanadium, lead, nickel.The purpose of adding is the composition structure that changes these heavy metal element oxide compounds by chemical process, the chemical ingredients of the back ash content that promptly burns, thus improve the ash content fusing point, to suppress of the corrosion of these elements to oil-burning apparatus.As in the internal combustion turbine heavy oil combustion, adding the nanometer oil-soluble magnesium salt, just can utilize magnesium and above-mentioned heavy metal element when high-temp combustion, to generate the ash content that fusing point is higher than internal combustion turbine turbine initial temperature (more than 1100 ℃), thereby avoid the generation of gas turbine hot passage parts high temperature corrosion.
Nano magnesium compound oil-soluble material of the present invention is to be raw material with magnesium oxide (or oxyhydroxide, magnesium salts etc.), mixes the back by a certain percentage with mineral oil, solvent wet goods medium and yin, yang ionic (or non-ionic type) tensio-active agent and reacts under certain process conditions and forming.Its concrete technical application scheme is as follows in detail:
(1) medium (mineral oil, solvent oil), magnesium oxide (or oxyhydroxide, magnesium salts) are added in the reactor, start stirring, thorough mixing evenly after, levigate through colloidal mill again, after having ground, stand-by.
(2) stablizer (ionic or nonionic surface active agent etc.) is added in the reactor, start stirring, and heat up gradually, slowly add above-mentioned (1) made mixture simultaneously.Behind reinforced the finishing, continue to be warming up to 350 ℃～400 ℃, system was reacted 4～6 hours, after sampling analysis was qualified, stopped reaction also was cooled to room temperature, added the appropriate amount of addition agent allotment again.After get product after the coarse filtration, smart filter.
When nano level magnesium compound oil-soluble material of the present invention was made the vanadium corrosion inhibiting additive of heavy (slag) oil, its addition can add in the ratio of Mg: V=3～3.5: 1 (weight ratio).
The technical characterstic of nano magnesium compound oil-soluble material of the present invention: the particle median size has reached nano-scale, and less than 20nm, and particle size, topographic profile are controlled good as the MgO particle, and be dispersed strong, nontoxic, is difficult for separating out throw out.
The present invention is described further by following embodiment:
1. magnesium oxide (magnesium hydroxide or magnesium salts) powder material 60g is joined in the organic solvent and stir, and add the paucidisperse agent.Deliver to colloidal mill after stirring again and finish grind, material is ground good back stand-by.
2. in there-necked flask, add mineral oil 150g, petroleum acid 25g, alkylsulphonic acid 22g starts stirring, and is warming up to 200 ℃ gradually, begins to drip above-mentioned 1 prepared magnesium oxide (magnesium hydroxide or magnesium salts) slurry then.After dropwising, continue to be warming up to 350 ℃～450 ℃, reacted 5 hours.Cool off then, lower the temperature, and sampling analysis.
3. by analysis, after each component content is qualified, add auxiliary agent again, organic solvent is allocated, carry out coarse filtration, smart filter at last and product.
