An antistatic silicone protective film and its preparation method

Abstract

This invention relates to the field of antistatic protective film technology and discloses an antistatic silicone protective film, comprising a substrate layer, a conductive static dissipation layer disposed at the upper end of the substrate layer, a superhydrophobic, anti-fouling, and wear-resistant layer disposed at the upper end of the conductive static dissipation layer, and an antistatic layer disposed at the lower end of the substrate layer. This antistatic silicone protective film and its preparation method achieve electrostatic protection from both sides of the film through the synergistic effect of the conductive static dissipation layer and the antistatic layer. The surface resistance remains stable over a long period, allowing for rapid dissipation of static electricity and preventing dust adsorption or damage to electronic components. The antistatic agent has good compatibility with the substrate resin and is not prone to migration or volatilization. Simultaneously, the fluorine-modified acrylate of the superhydrophobic, anti-fouling, and wear-resistant layer imparts superhydrophobic properties to the surface, making it difficult for fingerprints, oil stains, and other dirt to adhere and easy to wipe clean. The nano-silica and UV-cured cross-linked structure enhance the coating hardness, effectively preventing scratches during daily use and ensuring screen light transmittance and aesthetics.
