Description
Technical field
The application is related to one of carbon nano tube paste production process assistance test instrument, particularly a kind of grinding distribution
Carbon nano tube paste abrasive media inner hardness test device.
Background technology
CNT is as monodimension nanometer material, lightweight, and hexagonal structure connects perfection, has the power of many exceptions
, electricity and chemical property.
CNT has good mechanical property, and CNTs tensile strength reaches 50～200GPa, is 100 times of steel, close
Degree but only have steel 1/6, at least higher an order of magnitude than ordinary graphite fiber；Its elastic modelling quantity up to 1TPa, with diamond
Elastic modelling quantity quite, about the 5 of steel times.For the CNT of the solid wall with ideal structure, its tensile strength is about
800GPa.Although the structure of CNT is similar to the structure of macromolecular material, its structure is stablized than macromolecular material
Many.CNT is the material with highest specific strength that can prepare 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, to multiple
The performance of condensation material brings great improvement.
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
Under the hydraulic pressure of 1011 MPa（Be equivalent to the deep pressure of ten thousand metres under water）, due to huge pressure, CNT is crushed.Remove
After removing pressure, CNT has recovered shape as spring immediately, shows good toughness.This enlightenment people can utilize
CNT manufactures frivolous spring, as damping device on automobile, train, can significantly mitigate weight.
CNT has good electric conductivity, because the structure of CNT and the lamellar structure of graphite are identical, 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, as long as adulterating micro CNT in the composite, the heat of this composite
Conductance will be likely to be obtained very big improvement.
Because CNT has above-mentioned many excellent specific properties, therefore the research of CNT and nano material in recent years
More and more deep, the wide application prospect of CNT also 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 be 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%）, using this proportioning according to mix and blend work
Skill prepares dispersed uniform carbon nano tube paste.In the presence of surface activity, thickening agent, using high speed machine stirring and
The mode that ultrasonic agitation combines, makes conductive agent degree of scatter greatly improve.Carry out to being difficult to scattered carbon nanotube conducting agent
The pre-prepared of slurry reduces stirring in cell size for the next step and requires so as to reach preferable dispersion effect, up to
To preferable mixed effect.
The Chinese invention patent application of Application No. 201410114650.9 disclosed in 25 days June in 2014, its invention 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 is formulated.Lead
Electricity Functional body is spherical CNT group, spherical CNT aggregate or its with carbon black, acetylene black, carbon fiber, conductive stone
The combination of one or more of ink, Graphene.Preparation method is to add described conductive functional filler and dispersant in described ratio
Enter stirring in solvent, obtain premix material, by premix material in grinding machine for grinding, formed and include multiple particle diameters for 0.1～3 micron
Spherical CNT group electrocondution slurry.This carbon nanotube conducting slurry can be used as the conduction of lithium battery positive and negative pole material
Agent.
The mode that above-mentioned patent application, the stirring of the first high speed machine and ultrasonic agitation combine, is mainly suitable for small lot
Produce or the low aqueous dispersion of viscosity uses, produce in enormous quantities and substantially all disperseed using second sand mill.
And zirconium oxide bead is made up of raw material with micron order and Subnano-class zirconium oxide with yittrium oxide, for requiring
" no pollution " and high viscosity, the extra-fine grinding of high rigidity material and a kind of scattered grinding bead, just suitable performances requirement is higher
Carbon nano tube paste preparation.
Zirconium oxide bead, wear-resistant, long service life, therefore cost are also very high.However, some manufacturers, high for pursuing
Volume profit, employs cheap zirconium oxide bead inferior, or because molding key technology parameter is not controlled so that hardness number
Not up to standard, so that the rate of wear of zirconium oxide bead is fast, service life greatly shortens, and frequent replacing oxidation is informed by production line,
Cost is led to increase, for the sand milling tinuous production using zirconium oxide bead in a large number, after the zirconium oxide bead of Fast Wearing will enter
Procedure, leads to stopping production of production etc..However, the little zirconium oxide bead of the ball shape of zirconium oxide bead, especially diameter, internal hard
Degree is difficult to test again, therefore, so that chromium plating zirconium oxide bead is existed in a large number.
