NOVELTY - Corrosion-resistant light high-conductive carbon-based flexible conductive shielding film comprises a resin slurry, a conductive base material and an auxiliary agent. USE - The corrosion-resistant light high-conductive carbon-based flexible conductive shielding film is useful for electronic product including adhered to chip surface and mobile phone gap. ADVANTAGE - The shielding film has strong flexibility, and the carbon film is light, corrosion resistant, more suitable for electronic product, adhered to the chip surface and mobile phone gap, achieving excellent electromagnetic shielding performance, is easy to be oxidized in the moist air, not corrosion-resistant, with the time lapse, conductivity is gradually reduced, affecting the electronic product performance of the technical problem. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing a corrosion-resistant, lightweight, highly conductive carbon-based flexible conductive shielding film, comprising (i) preparing carbon-based conductive film slurry, adding resin slurry and additives to the reaction vessel, dispersing the additives at high speed, adding carbon nanotube dispersion liquid, stirring evenly, adding carbon-based materials, and obtain carbon after stirring sufficiently conductive film paste, (ii) casting carbon-based conductive film slurry to form a film by a cast coater, drying in oven at 50-100℃ to form a carbon-based conductive film, (iii) placing carbon-based conductive film on the release film for transmission, and calendaring with a calender, a heating table before the calender feeds the film, heating diaphragm by the heating table and pressing through the gap, and (iv) rolling and pressing carbon-based conductive film, and placing in an oven at 120-160℃ for annealing, pressurizing the carbon-based conductive film, and the pressurization method is crimp wrapping pressurization or flat plate pressurization.
