The antistatic agent selected in the antistatic coating should be closely integrated with the compatibility of the matrix resin and the dispersibility in the resin. The antistatic agent has good compatibility with the matrix resin, which is conducive to the antistatic effect; compatibility If it is not good, the antistatic agent molecules will diffuse rapidly in the coating, and the surface of the coating will quickly become oily. Generally, ionic antistatic agents are mostly used for polar resins, and low-polarity nonionic antistatic agents are used for weakly polar resins or non-polar resins.
For example, epoxy resin 821 alone or in combination with other epoxy resins is used as the main component of the film-forming material, polyamide resin is used as a curing agent, and the addition of polyoxyethylene type quaternary ammonium salt antistatic agent can also promote the curing of epoxy resin, and A hard, transparent antistatic film can be obtained. If this kind of coating is used to impregnate polyethylene board, polystyrene board, methacrylate board, polyester film, etc., and dry at 60°C for 30 minutes, a transparent film is formed on the surface of the sample, measured at 24°C and RH57% The friction band voltage is listed in Table 11-6.

The decomposition of conductive agent 421 does not affect the printability of the coating film;
