preparation example Construction

[0072] The present invention also discloses a continuous preparation method of carbon nanotube film, the preparation method adopts the above-mentioned continuous preparation device of carbon nanotube film, refer to Figure 1 to Figure 6 Shown, this preparation method comprises the following steps:

[0073] The carbon nanotube macroscopic body is produced by floating catalytic chemical vapor deposition, and the carbon nanotube macroscopic body is blown out from the outlet end of the furnace tube through the carrier gas.

[0074] The carbon nanotube macroscopic body is automatically and continuously wound on its surface by a rotating collecting drum. In this step, the carbon nanotube macroscopic bodies may be uniformly arranged in multiple rows along the axial direction of the collection drum, and at the same time may be arranged in multiple layers along the radial direction of the collection drum.

[0075] After the collection of the carbon nanotube macroscopic body is complet...

Embodiment 1

[0083] 1. Clean the inside of the box, close the flip door, close the sealing system of the furnace mouth, and close the solenoid valve to ensure the inside of the box is sealed.

[0084] 2. Turn on the vacuum pump, and use protective gases such as argon and nitrogen to discharge the air inside the box from the exhaust system through the replacement method, so as to reduce the oxygen content inside the box to a safe range.

[0085] 3. Turn off the vacuum pump, open the furnace mouth sealing system, open the solenoid valve, and at the same time pass protective inert gases such as argon or nitrogen into the box, and then pass carbon source gas or liquid into the interior from the entrance section of the high-temperature furnace tube. Catalyst, hydrogen, argon and other carrier gases are used to produce carbon nanotubes by the floating catalytic chemical vapor deposition method. The carrier gas will blow out the cylindrical macroscopic body of carbon nanotubes formed and assembled i...

Abstract

The invention provides a continuous collection device, preparation device and preparation method of a carbon nanotube film. The continuous collection device comprises a collecting box body and an independent and movably arranged transfer drying device, wherein two opposite side walls of the collecting box body are respectively provided with an outlet and an inlet; a collecting roller, a transmission mechanism, a cutting mechanism and an infiltration mechanism are arranged in the collecting box body; the cutting mechanism is located above the infiltration mechanism, and the cutting mechanism and the infiltration mechanism are both arranged on the inner side wall of the collecting box and close to the outlet; the relative position of the collecting roller and the inlet is adjusted through the transmission mechanism, and the collecting roller is controlled to rotate; and the transfer drying device is matched with the collecting box body to transfer the carbon nanotube film formed in the collecting box body to the outside and dry the carbon nanotube film. The continuous collection device realizes the continuous and automatic collection, cutting, infiltration and transfer of a macroscopic body of the carbon nanotube, reduces the manual operation process, and realizes the automatic continuous production.

Description

technical field [0001] The invention relates to the technical field of preparation of carbon nanotube films, in particular to a continuous collection device and preparation device of carbon nanotube films and a preparation method thereof. Background technique [0002] Carbon nanotubes have a unique hollow tubular one-dimensional structure, and its structure has rich control space, and has excellent characteristics such as high strength, light weight, good electrical conductivity, and strong environmental tolerance. However, the practical value of carbon nanotubes at the micro-nano scale is low, and the preparation of macro-scale carbon nanotube materials is the basis for their large-scale and engineering applications. [0003] Carbon nanotube film is a two-dimensional macroscopic material composed of long-range ordered arrangement of micro-nanoscale carbon nanotubes. It has great application potential in the fields of far-infrared heating, electromagnetic shielding, and spac...
