Embodiment

[0015] The attached drawing shows a schematic structural view of the nanoparticle and carbon nanotube dispersing device of the present invention. The dispersing device is composed of a cylinder body 3, a piston rod 1 and a heating jacket 2. The cylinder body 3 is in the shape of a dumbbell with a thin middle part, and a piston rod 1 is respectively installed in the inner cavities at both ends of the cylinder body, forming a syringe-like container. A sealing ring can be installed on the outer circle of the piston rod 1 to increase the sealing performance. A heating jacket 2 is installed on the outside of both ends of the cylinder, and the heating jacket 2 is wrapped on the cylinder in a cylindrical shape. The heating jacket 2 is equipped with a resistance wire, which is heated by electricity to melt the polymer matrix material.

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 [0001] The invention relates to methods and devices for dispersing nanoparticles and carbon nanotubes. Background technique [0002] As we all know, nanoparticles are easy to agglomerate because of their high surface activity, so that various peculiar effects of nanomaterials cannot be fully exerted, which limits their application in high-performance polymers. Traditionally, ultrasonic, high-energy radiation, three-roller and ball-mill assisted dispersion are used for the dispersion of nano-powder, but the dispersion effect is not very satisfactory. Therefore, how to solve the dispersion problem of nanomaterials and explore new dispersion processes of nanomaterials has become a hot spot in future research. The mechanical dispersion method and device involved in the present invention have not been reported in domestic and foreign literature and patents. Contents of the invention [0003] The invention aims at the deficiencies in the existing nanoparticle a...
