Degree but only has the 1/6 of steel, at least higher an order of magnitude than ordinary graphite fiber；Its elastic modelling quantity is up to 1TPa, with diamond
Elastic modelling quantity suitable, about 5 times of steel.For having the CNT of the solid wall of ideal structure, its tensile strength is about
800GPa.Although the structure of CNT is similar to the structure of macromolecular material, but its structure is stablized than macromolecular material
Many.CNT is the material with high specific strength can prepared at present.If will be with Other Engineering material as matrix and carbon
Nanotube makes composite, and composite material exhibits can be made to go out good intensity, elasticity, fatigue resistance and isotropism, gives multiple
The performance of condensation material brings improvement greatly.
The hardness of CNT is suitable with diamond, but has good pliability, can stretch.In October, 2000, beautiful
The research worker of Pennsylvania State University of state claims, and the intensity of the strength ratio same volume steel of CNT is high 100 times, after weight but only has
1/6 to the 1/7 of person.CNT thus claimed " super fiber ".CNT was once placed in by the research worker of Moscow State University
(being equivalent to the pressure that ten thousand metres under water are deep) under the hydraulic pressure of 1011 MPa, due to huge pressure, CNT is crushed.Remove
After removing pressure, CNT has recovered shape as spring immediately, shows good toughness.These enlightenment people can utilize
CNT manufactures frivolous spring, is used on automobile, train as damping device, it is possible to significantly alleviate weight.
CNT has good electric conductivity, owing to the structure of CNT and the lamellar structure of graphite are identical, and institute
To have good electric property, electrical conductivity is generally up to 10,000 times of copper.
CNT has good heat transfer property, and CNT can synthesize the heat conducting material of high anisotropy.Separately
Outward, CNT has higher thermal conductivity, if the CNT of the trace that adulterates in the composite, the heat of this composite
Conductance will be likely to be obtained the biggest improvement.
Owing to CNT has above-mentioned many excellent specific properties, therefore the research of CNT and nano material in recent years is also
More and more deep, the application prospect that CNT is wide the most constantly shows.
The Chinese invention patent application of Application No. 201510950204.6 disclosed in 4 days Mays in 2016, its innovation and creation
Entitled " a kind of lithium battery carbon nano tube paste and preparation method thereof ", the composition in carbon nano tube paste is carbon nanometer
Pipe, carbon black, surfactant, thickening agent, solvent.Its proportioning is, CNT: carbon black: surfactant: thickening agent: solvent=
(3 ~ 10wt%): (0 ~ 8wt%): (0.1 ~ 1.3wt%): (0 ~ 1wt%): (80 ~ 96wt%), uses this proportioning according to mix and blend work
Skill prepares dispersed uniform carbon nano tube paste.Surface activity, thickening agent effect under, use high speed machine stirring and
The mode that ultrasonic agitation combines, makes conductive agent degree of scatter be greatly improved.Carry out being difficult to scattered carbon nanotube conducting agent
Slurry pre-prepared so that it is reach preferable dispersion effect, reduce next step stirring requirement being used in cell size, up to
To preferable mixed effect.
The Chinese invention patent application of Application No. 201410114650.9 disclosed in 25 days June in 2014, it invents wound
Entitled " the carbon nanotube conducting slurry and its production and use " made, carbon nanotube conducting slurry by conductive functional filler,
Conductive functional filler pressed by dispersant, solvent: dispersant: solvent=2～10:0.2～5:85～97.8 mass ratio formulated.Lead
Electricity Functional body is Spherical Carbon nanotube group, Spherical Carbon nanotube aggregate or it is with carbon black, acetylene black, carbon fiber, conduction stone
The combination of one or more in ink, Graphene.Preparation method is described conductive functional filler and dispersant to be added in described ratio
Entering in solvent and stir, obtain premix material, by premix material in grinding machine for grinding, it is 0.1～3 micron that formation includes multiple particle diameter
The electrocondution slurry of spherical CNT group.This carbon nanotube conducting slurry can be as the conduction of lithium battery positive and negative pole material
Agent.
Above-mentioned patent application, the mode that the stirring of the first high speed machine and ultrasonic agitation combine, it is mainly suitable for small lot
Produce or the low aqueous dispersion of viscosity uses, produce in enormous quantities and the most all use the second sand mill to disperse.
And zirconium oxide bead is made for raw material with micron order and Subnano-class zirconium oxide with yittrium oxide, it is used for requiring
" no pollution " and high viscosity, the extra-fine grinding of high rigidity material and scattered a kind of grinding bead, be just suitable for performance requirement higher
The preparation of carbon nano tube paste.
Zirconium oxide bead, wear-resistant, service life is long, and therefore cost is the highest.But, some manufacturer, for pursuing height
Volume profit, have employed cheap zirconium oxide bead inferior, or because molding key technology parameter is not controlled well so that hardness number
The most up to standard, so that the rate of wear of zirconium oxide bead is fast, service life is greatly shortened, and production line is informed frequently changing oxidation,
Cost is caused to increase, for a large amount of sand milling tinuous productions using zirconium oxide bead, after the zirconium oxide bead of Fast Wearing will enter
Procedure, causes the stopping production etc. produced.But, the zirconium oxide bead that the ball shape of zirconium oxide bead, especially diameter are little is internal hard
Degree is difficult to again test, and therefore, also makes chromium plating zirconium oxide bead exist in a large number.
