Abstract

The invention provides a carbon nanotube composite plastic and a preparation method thereof, and relates to the field of composite materials. The carbon nanotube composite plastic is formed through processing raw materials comprising a plastic and a carbon nanotube complex. A preparation method of carbon nanotube powder comprises the following steps: allowing a carbon nanotube catalysis element toform nanometer distribution on the surface of maifan stones in order to obtain a catalyst precursor; carrying out high temperature calcination to obtain a catalyst used for producing carbon nanotubes; placing the catalyst in a high temperature device, introducing a mixed gas containing C7 or less organic gases, an inert gas and a reducing gas, controlling the temperature at 500-1200 DEG C, and controlling the air speed of the mixed gas at 0.1-100 h<-1> in order to prepare the carbon nanotube powder. The carbon nanotube complex having an excellent phase connection fully performs the excellentperformances of the carbon nanotubes and the maifan stones and overcomes the disadvantages of the application of existing carbon nanotubes and mainfan stones to the composite plastic when applied to the plastic in the invention.

Description

technical field [0001] The invention belongs to the field of composite materials. Background technique [0002] Carbon nanotubes are one-dimensional quantum materials with special structures. Carbon nanotubes are mainly composed of coaxial circular tubes with several to tens of layers of carbon atoms arranged in a hexagonal shape. A fixed distance is maintained between layers, about 0.34nm, and the diameter is generally 2 to 20nm. According to the number of graphite layers, carbon nanotubes can be divided into single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs). Carbon nanotubes have good mechanical properties, their tensile strength is 100 times that of steel, their density is only 1 / 6 of that of steel, and their modulus of elasticity is about 5 times that of steel. Although the structure of carbon nanotubes is similar to that of polymer materials, its structure is much more stable than that of polymer materials, and it is one of the material...
