제목 Effect of phosphorus flame retardants on the properties of polyurethane foams
초록 Mechanical properties with urethane foam completed the identification process through foaming magnitude, rebound resilience, specific gravity, hardness, tearing strength, tensile strength, elongation, and compression set (CS). Measurements of limit oxygen index(LOI) and combustibility were carried out to check flame retardancy. As for the basic responsibility in foaming, it was identified by rising time(RT), cream time(CT), and tack free time(TFT).  LOI values of polyurethane foam showed an increase as the capacity of flame retardants rose, showing a reduction in after-flame time by the flammability test. As a result, an addition of phosphorus-based flame retardants revealed an increase in flame retardancy along with a rise in capacity. However, an increase in flame retardant capacity indicated a rise in RT, CT and TFT, which brought about the consequence of delaying the discharge of urethane foam. Mechanical properties presented a slight difference according to flame retardants, but showed similar characteristics to the properties of the existing halogen-containing flame retardants.
