Abstract
The present invention provides nanometer particle and carbon nanotube dispersing method and device. The dispersing method is setting the mixture of the nanometer particle or the carbon nanotube and the base material inside one cylinder with piston rod and beating the mixture with the piston rod repeatedly. The dispersing device consists of a cylinder, a piston rod and heating jacket. There are two piston rods set separately inside the two end of the inner cavity of the dumbbell-shaped cylinder with a thin middle part, and one heating jacket around the cylinder. The present invention disperses nanometer material mechanically, and has high dispersion effect, high yield, less impurity introducing, and capacity of dispersing and straightening carbon nanotube.
Description
Technical field
The present invention relates to be used for the method and the device of dispersing nanometer particle and CNT.
Background technology
As everyone knows, nano particle is easy to reunite because of having very high surface-active, makes the various peculiar effect of nano material not give full play to, and has limited its application in high-performance polymer.Tradition is taked technologies such as ultrasonic, high-energy radiation, three rollers and ball milling aid dispersion more to the dispersion of nano powder, but dispersion effect is not very good.Therefore, the dispersion new technology that how to solve the dispersion problem of nano material and explore nano material becomes the focus of future studies.Mechanical dispersion process involved in the present invention and device, domestic and foreign literature and patent there is no report.
Summary of the invention
The present invention is directed to the deficiency that existing above-mentioned nano particle and CNT dispersion technology exist, a kind of dispersion effect is good, productive rate the is high nano particle and the process for dispersing and the device thereof of CNT are provided.
For achieving the above object, the present invention adopts following technical solution:
The process for dispersing of nano particle of the present invention and CNT is:
The mixture of nano particle or CNT and matrix material is put into the cylindrical shell of a band piston rod, with piston rod mixture is lashed repeatedly and to get final product.
Cylindrical shell middle part described in the above-mentioned process for dispersing is thinner than two ends, and two ends all have piston rod, and cylindrical shell is heated.Piston rod with cylindrical shell one end pushes in the inner chamber of the other end, and the piston rod with the other end pushes back again, lashes so repeatedly to get final product.
The mixture that above-mentioned process for dispersing makes nano particle and CNT and matrix material can form the jet phenomenon during through the thinner middle part of cylindrical shell, form the mixture flow at high speed, nano particle can be realized preliminary orientation and dispersion with melt flows, simultaneously enter the cylindrical shell other end and form further superimposed stacking through the melt of necking down, finish once more and disperse, lash so repeatedly, will cause superposeing repeatedly on the original basis dispersion, thereby significantly improve the dispersion effect of nano particle and CNT.Heating can be played the effect of molten polymer matrix material to cylindrical shell.
The nano particle of the above-mentioned process for dispersing of realization of the present invention and the dispersal device of CNT are made up of cylindrical shell, piston rod and heating jacket, and cylindrical shell is the thin dumbbell shape in middle part, and a piston rod respectively is housed in the inner chamber of cylindrical shell two ends, and heating jacket is housed on the cylindrical shell.
Heating jacket becomes cylinder type to be coated on the cylindrical shell, is provided with resistance wire in it.Heating jacket plays the effect of molten polymer matrix material.
The present invention utilizes mechanical means that nano material is disperseed, and dispersion effect is good, and the productive rate height has reduced the introducing of impurity, can accomplish dispersion and cut-off to CNT.Compare dispersion back nano particles with other dispersing modes and obviously reduce, unit volume endoparticle number increases and is evenly distributed, and disperses can see that the cluster shape is the parallel arrangement CNT from TEM shines for CNT.

The specific embodiment
Embodiment:
Accompanying drawing has provided the structural representation of nano particle of the present invention and CNT dispersal device.This dispersal device is made up of cylindrical shell 3, piston rod 1 and heating jacket 2.Cylindrical shell 3 is the thin dumbbell shape in middle part, and a piston rod 1 respectively is housed in the inner chamber of cylindrical shell two ends, has formed the container of a syringe type.On the cylindrical of piston rod 1 sealing ring can be housed, to increase sealing.A heating jacket 2 respectively is equipped with in the outside, cylindrical shell two ends, and 2 one-tenth cylinder types of heating jacket are coated on the cylindrical shell, are provided with resistance wire in it, adopts electrical heating, plays the effect of molten polymer matrix material.
With nano particle or CNT and matrix material (solution or polymer melt; mixture for example: the slip or the ABS resin that are used for ceramic gel casting forming) is put into an end inner chamber of cylindrical shell 3; push with piston rod 1 in the inner chamber of the other end; piston rod with the other end pushes back again; mixture can form the jet phenomenon during through the thinner middle part of cylindrical shell 3; form the mixture flow at high speed; nano particle can be realized preliminary orientation and dispersion with melt flows; simultaneously enter the cylindrical shell other end and form further superimposed stacking through the melt of necking down; finish once more and disperse; lash so repeatedly; to cause superposeing repeatedly on the original basis dispersion, thereby significantly improve the dispersion effect of nano particle and CNT.Reach nano particle, CNT is uniformly dispersed and the purpose of CNT cut-off.
