PURPOSE: A conductive one liquid phase polyurethane-based adhesive composition and its preparation method are provided, to enable the adhesive composition to be cured to show an excellent adhesive strength without additional curing accelerator, thereby reducing the working time and improving the convenience of construction. CONSTITUTION: The polyurethane-based adhesive composition comprises 100 parts by weight of a one liquid phase polyurethane adhesive composition comprising 20-40 wt% of a two functional polyether polyol with a number average molecular weight of 1,000-3,000, 15-20 wt% of a three functional polyether polyol with a number average molecular weight of 3,000-6,000, 10-13 wt% of toluene diisocyanate, 10-15 wt% of diphenylmethane diisocyanate, 0.5 wt% of a two functional glycol comprising 1,4-butanediol, 0.2-0.5 wt% of benzoyl chloride, 0.8-1.0 wt% of sodium silicoaluminate, 12-15 wt% of toluene, 11-14 wt% of ethyl acetate, and 0.5-1.0 wt% of methylethylketone; 5-15 parts by weight of a filler comprising clay; and 5-15 parts by weight of a conductive material comprising carbon black.
