Problems solved by technology

The problem of such dry coating for depositing inorganic metal oxides such as ITO is that not only the raw material itself is expensive, but also consumes too much process cost in the deposition process, and in the inorganic metal oxides that are typically used Indium (indium), the main raw material of ITO, is a limited mineral, and it is rapidly depleted with the expansion of the display market. Therefore, the actual situation is that the price will inevitably increase.

Embodiment 1～3 and comparative example 1～3

[0105] Solvents (first solvent and second solvent) and inorganic adhesive agent, and stirred at a speed of 1000 rpm for 40 minutes to completely mix the acrylic organic binder and inorganic binder with the solvent. While continuing to stir, drop the PEDOT / PSS conductive polymer aqueous dispersion at a rate of 5 g / min, and finally add the surface adjustment additive and mix uniformly for about 1 hour at a rate of 1000 rpm To prepare the coating liquid composition.

Abstract

The invention relates to a method for producing a conductive coating liquid composition with electromagnetic wave shielding function. The composition comprises by weight %: 1.0-20.0% of acrylic organic binder; 10.0-65.0% of PEDOT / PSS conductive 25.0-65.0% of the solvent for dispersing or dissolving the PEDOT / PSS conductive polymer and 0.1-7.0% of the inorganic binder, the PEDOT / PSS conductive polymer aqueous dispersion is An aqueous dispersion of polystyrene sulfonic acid is incorporated into polyethylene dioxythiophene, the molar ratio of polyethylene dioxythiophene and polystyrene sulfonic acid is 1:1 to 5, and the acrylic organic binder is composed of different An acrylic polymer composition obtained by polymerizing a first acrylic monomer having a hydroxyl group and 10 to 200 parts by weight of a second acrylic monomer having a hydroxyl group with respect to 100 parts by weight of the first acrylic monomer.

Description

technical field [0001] The present invention relates to a conductive coating liquid composition, a method for producing the same, and a conductive coating film produced by using the above-mentioned composition. More specifically, it relates to a low-temperature curable composition that can be easily applied by a wet coating method. The coating film cured after being coated has flexibility, has excellent adhesion to glass or film, has electromagnetic wave shielding properties, and has high transparency and high conductivity. Conductive coating liquid composition, Its production method and the conductive coating film with electromagnetic wave shielding function produced by using the composition. Background technique [0002] Recently, most of mobile devices or automation devices in use are equipped with a touch screen panel TSP (touch screen panel; hereinafter referred to as “TSP”). The so-called TSP refers to a screen in which specific processing is performed by confirming t...
