The invention relates to a coating film material and an application method thereof, wherein the coating film material comprises the following components in percentage by mass: 48-99% of liquid epoxy resin, 1-45% of bridging agent, 0-10% of anticorrosive agent, 0-27% of hardening accelerator and 0-18% of other auxiliary agents. By adjusting the proportion of the liquid epoxy resin and the bridging agent, the coating film formed on the surface of the carbon nanotube fiber after reaction has flexibility, good ductility and toughness, and can be used for physical bending and stretching under various conditions, so that the normal use of the carbon nanotube fiber wire is ensured; the anticorrosive agent is introduced to prevent chemical or biological erosion and oxidation and prolong the service life of the coating film material; the hardening accelerator is introduced, and the curing speed and time of the coating material are adjusted by adjusting the using amount of the hardening accelerator, so that the coating effect is optimal. |
