The present invention relates to a constructing method of a flame retardant polyurethane flooring material, and more particularly, to a constructing method of a flame retardant polyurethane flooring material, enabling construction of the flame retardant polyurethane flooring material with only five steps which includes: a surface treatment process; a first primer application process; a non-combustible material stacking process; a second primer application process; and an application process of a ′flame retardant polyurethane flooring material composition′ which is previously registered (Korean Patent Publication No. 10-1454357) by the applicant of the present invention. The present invention relates to the constructing method of the flame retardant polyurethane flooring material, capable of reducing air and a weight. In addition, by using the ′flame retardant polyurethane flooring material composition′ which is previously registered by the applicant of the present invention as described above, supplying at low costs is possible, costs for repairing are also not consumed due to lack of a crack or a desorption phenomenon, slip resistance is shown even when exposed to a haze or sea water during a voyage, and particularly, flame retardancy is improved such that flame propagation ability, smokability, and toxicity satisfies a national defense standard (KDS 7220-4001). |
