The purpose of this study is to design a halogen-free, phosphorus flame retardant polyurethane resin composition formulation possessing suitable mechanical properties for use. The flame-retardant performance of the laminating fabric, to which the synthesized flame-retardant polyurethane resin composition of optimal conditions was applied, was confirmed. Through Fourier-transform infrared spectroscopy analysis, it was possible to confirm the specific peak of the urethane reaction and the flame-retardant polyurethane resin. As the amount of phosphorus-based flame-retardant polyol increased, the elongation and tensile strength decreased. As the content of the chain extender increased, the tensile strength increased but the elongation decreased. The content of the flame retardant polyol and the molar ratio of the chain extender and the diisocyanate were kept constant, and the molar ratio of the low molecular weight polyol to the high molecular weight polyol was adjusted. As a result, a phosphorus polyurethane possessing appropriate mechanical properties and excellent flame retardancy with a tensile strength of 432kg/ and an elongation of 423% was synthesized. In addition, when dimethylacetamide was used instead of dimethylformamide as a solvent, similar levels of physical properties were observed, confirming the applicability of an eco-friendly solvent. The flame retardancy of the triple-laminated fabric for safety protective clothing applied with the newly developed flame-retardant polyurethane resin and the triple-laminated fabric for wall coverings met the standards of flame retardant products.
