Document Type and Number:

WIPO Patent Application WO/2017/010620

Kind Code:

A1

Abstract:

The present invention relates to a method for preparing a water-dispersible polyurethane resin-based conductive film, and a water-dispersible polyurethane resin-based conductive film prepared thereby, wherein the method enables an increase in productivity and a small amount of unit production through a characteristic preparation environment, and allows the water-dispersible polyurethane resin-based conductive film to have excellent elasticity while being environmentally friendly, harmless to the human body and lightweight, have excellent mechanical, chemical and electrical characteristics, and be able to have crack impact strength allowing flexibility even in sub-zero environment. According to the present invention, provided is a method for preparing a water-dispersible polyurethane resin-based conductive film, comprising: a conductive film resin composition preparation step of preparing a conductive film resin composition; a defoaming step for removing the bubbles contained in the resin composition prepared from the conductive film resin composition; a coating step of coating the defoamed resin composition on heat resistant release paper; and a drying/foaming step of obtaining a conductive film by drying and foaming the resin composition coated on the release paper.
