Abstract

The invention discloses a functional polymer coating containing CNTs and used for automobiles. The functional polymer coating is characterized by being prepared from the following components in partsby weight: 52-54 parts of a carbon nanotube isocyanate composite component, 17-19 parts of a hydroxyl component and 28-30 parts of a butyl acetate solvent. A preparation method of the coating comprises the following steps: S1, acidifying the multi-walled carbon nanotubes; S2, preparing a first mixed solution and carrying out grinding to obtain a second mixed solution; S3, preparing the carbon nanotube composite isocyanate component; and S4, preparing the carbon nanotube polyurethane nanocomposite coating. According to the material and the preparation method provided by the invention, the dispersion effect of carbon nanotubes can be enhanced, and the mechanical properties of the coating are enhanced. With equipment provided by the invention, the amount of the second mixed solution attachedto the inner wall of a grinding cavity can be reduced, and the waste of the second mixed solution is avoided.
