Abstract

The invention relates to a nanometer material addition agent, which is prepared by adopting the steps: 1) dispersing agent is added into a carbon nano-tube (CNT) and is mixed evenly; the weight content of the mixed dispersing agent can not be lower than 90 percent of the total weight of the dispersing agent and the carbon nano-tube; 2) the carbon nano-tube with dispersing agent is arranged into an ultrasonic wave field for ultrasonic dispersion. The nanometer material addition agent has a better stable electrostatic conductive performance, and the amplitude modulation of the added quantity of other adding components is large, thereby various electrostatic conductive coating with special characteristics can be designed and prepared according to requirement. The nanometer material addition agent adopts CNTs as a conductive function body to prepare electrostatic conductive coating, which embodies the important application of nanotechnology in transforming the traditional industries; furthermore, the electrostatic conductive coating has a more excellent performance, and the nanometer material addition agent is a new approach for the large-scale industrial application of CNTs.

Description

technical field [0001] The invention relates to a nanometer material additive. Background technique [0002] Micro-nano powders, especially nano-powders, have fine particle size, large specific surface area, high surface energy, increased number of surface atoms, and insufficient atomic coordination, which make these atoms highly active, extremely unstable, and easy to form Agglomerates of several larger sizes connected at the interface. The formation of these aggregates prevents nanoparticles from being uniformly dispersed as a single particle, and cannot exert its proper nano-characteristics, which has a very adverse effect on the application performance of nano-particles. [0003] An important application of nanopowders in the chemical industry is for coatings. The "small size effect", "interface effect", "quantum size effect" and "macro particle tunneling effect" of nanoparticles make nanomaterials Aspects such as structure, optoelectronics, magnetism and chemical prop...
