ELECTROCONDUCTIVE COMPOSITION, ELECTROCONDUCTIVE COATING, ELECTROCONDUCTIVE FIBER MATERIAL AND EXOTHERMIC ARTICLE IN PLANE SHAPE

Document Type and Number:

WIPO Patent Application WO/2005/012428

Kind Code:

A1

Abstract:

An electroconductive composition witch comprises 100 parts by weight of a polyether polyurethane (A) prepared by the copolymerization of 33 to 53 wt % of a C_8-22 aromatic polyfunctional isocyanate (a) and 47 to 67 wt % of a polyether polyol (b) having a C _3-6 oxypolymethylene recurring unit or a 100 parts by weight of a polycarbonate polyurethane (B) prepared by the copolymerization of 13 to 33 wt % of the above isocyanate (a) and 67 to 87 wt % of a polycarbonate polyol (c) having a C _3-6 oxycarbonyl oxypolymethylene recurring unit, and 70 to 180 parts by weight of an electroconductive material (C), wherein the electroconductive material (C) preferably comprises a flake graphite carbon and a carbon black exhibiting a low dibutyl phthalate oil absorption. The electroconductive composition is excellent in the adhesion to a base material and the resistance to hydrolysis, and is applied to a fiber material as a coating to provide an electroconductive fiber material.
