Abstract
A process for preparing nano metre graphite carbon powder from nanometre graphite carbon sol includes such steps as adding cladding agent 0.1-5% to the said sol, stirring touniformity, heating to 30-70 deg.C for fully drying it and grinding the resultant granular of flaky substance to fine powder. Its advantages are simple process, low cost and high dispersity of product.
Description
The present invention relates to a kind of method for preparing carbon powder from nano graphite, particularly a kind of method with preparing nano graphite carbon powder from nano graphite sol.
Studies show that to have many excellent characteristic at the graphite carbon of nano-scale range in a large number, its many industries that are applied as are brought great technological breakthrough and technological revolution, and its Application Areas also constantly enlarges.But when the graphite carbon size reached nanometer range, because it has intensive adsorptivity and electronegative, the nano-graphite carbon materials was easily reunited, the difficult dispersion thereby make, the maximum difficult point that becomes the preparation of nano-graphite carbon materials and use.Have only a few countries to produce at present in the world, and the domestic report that does not also have to produce less than the 30nm carbon powder from nano graphite.
Prepare carbon powder from nano graphite, at first to prepare nano-graphite colloidal sol, the method for preparing nano-graphite colloidal sol is: Graphite Electrodes is arranged by positive and negative electrode put into oxidation trough, just, separate with plastic wire between the negative potential, electrode adopts series-parallel system with being connected of power supply, electrolytic solution is poured in the oxidation trough again, connected power supply, current control is at 5～150A, voltage control is at 3～20V, carry out oxide treatment, controlled temperature stirs once every 4～12 hours below 80 ℃, detect graphite carbon concentration in the groove, collosol concentration is 0.1～5% o'clock, and oxidation finishes, and solution is nano graphite carbon sol in the groove.
The objective of the invention is to: provide a kind of and add coating agent in nano-graphite colloidal sol, make the outer parcel that forms of nano-graphite carbon granule, the graphite carbon particle is easily reunited, difficult dispersive problem thereby solved.
The present invention be achieved in that it be will make nano-graphite colloidal sol add coating agent and get, coating agent with nano graphite carbon sol adding 0.1～5%, add in the dry vessel after stirring, heating then, controlled temperature is at 30～70 ℃, behind the colloidal sol complete drying, the material of slabbing or macrobead shape is ground to form fine powder promptly.
Described coating agent comprises: lignin matter, oleic acid, fish oil, nano silicon, the connection agent of metatitanic acid matter corner, weight percent shared in colloidal sol is: lignin matter 0.1～3%, oleic acid 0.1～2%, fish oil 0.1～2%, nano silicon 0.1～3%, the connection agent 0.1～2% of metatitanic acid matter corner.Coating agent can add separately, also can mix adding.
The present invention compared with prior art, it is simple to have processing method, production cost is low, is suitable for suitability for industrialized production, the product particle degree is little, advantages such as good dispersity.It solved in the carbon powder from nano graphite preparation easily reunite, a difficult dispersive difficult problem, its granularity is less than 15nm, dispersiveness reaches 100% in water.Can be widely used in industries such as battery, oil, chemical industry, electronics, agricultural, health care, material modification, and will bring a series of major technological breakthroughs for these industries.
Embodiments of the invention: produce nano-graphite colloidal sol earlier, Graphite Electrodes is put into oxidation trough by the positive and negative electrode arrangement, separate with plastic wire between the positive and negative electrode, electrode adopts series-parallel system with being connected of power supply, again electrolytic solution is poured in the oxidation trough, connect power supply, current control is at 5～150A, and voltage control is carried out oxide treatment at 3～20V, controlled temperature is below 80 ℃, stirred once every 4～12 hours, detect graphite carbon concentration in the groove, collosol concentration is 0.1～5% o'clock, oxidation finishes, and solution is nano graphite carbon sol in the groove.Get concentration and be 0.1～5%, granularity more than 80% less than the nano-graphite colloidal sol of 10nm, the lignin matter that adds colloidal sol weight 3%, 2% oleic acid, pack into after stirring in the dry vessel, heating then, controlled temperature begins to vacuumize at 30～70 ℃ simultaneously, after treating the colloidal sol complete drying, the material of slabbing or macrobead shape is ground to form fine powder promptly.
