NOVELTY - Method for preparing fabric antistatic finishing agent, involves (i) reacting diisocyanate monomers with vinyl-containing unsaturated diols to form cyanate-terminated polyurethane oligomers, (ii) reacting the polyurethane oligomer obtained in step (i) with a vinyl-modified conductive filler, and grafting the conductive filler on the surface of the polyurethane oligomer to obtain a synthetic product, (iii) reacting the synthetic product obtained in step (ii) with polyether diol to obtain a polyurethane/conductive filler compound, and (iv) mixing the polyurethane/conductive filler compound obtained in step (iii) with an emulsifier, leveling agent, antifoaming agent and bridging agent, and reacting to obtain the antistatic finishing agent. USE - The method is used for preparing fabric antistatic finishing agent in fabric finishing technology. ADVANTAGE - The fabric antistatic finishing agent has outstanding antistatic effect and long-term stable performance under low filler adding amount.
