Speaking of paint, everyone may be familiar with it. Every household always needs some paint to decorate the walls, but did you know? The coating industry also needs antistatic agents. Why is this? Most paints use various flammable solvents as diluents. The static electricity generated during spraying can easily ignite and explode the gases of these solvents during discharge.
Cationic antistatic agentThe principle of action is to utilize its cationic surface Active properties, adsorb moisture in the air, polarize itself, form an extremely thin conductive layer on the surface, leak electrostatic charges through different channels or reduce the friction factor to suppress the generation of electrostatic charges. Constitutes a static leakage channel, so its effect depends on its own structure and the relative humidity of the environment.
The coating industry requires many kinds of surfactants, including emulsifiers, pigment surface treatment agents, pigment wetting and dispersing agents, defoaming agents, leveling agents, anti-mildew agents, bactericides, and antistatic agents , gloss enhancer, slip agent.
Among them, selectantistatic agent At that time, several things need to be done to be a qualified paint antistatic agent.
① Great effect in preventing static electricity
② Prevent static electricity effect from lasting
③ Good miscibility with film-forming substances
④ Does not affect other properties of the paint, such as not making the paint film yellow.
