Synthesis of reactive phosphate and its effect on the mechanical and flame retardant properties of thermoplastic polyurethane elastomer
A dihydroxyl phosphate called butyl bis（4-hydroxybutyl） phosphate was synthesized. The mechanical and flame retardant properties of TPU were investigated by different additive amount of BBHP. It was found that with the increasing of BBHP, the mechanical strength performance of TPU decreased, but the flame retardant of TPU improved. When the additive amount of BBHP came up to 12%, the tear strength of TPU was up to maximum. The oxygen index of TPU reached more than 27 with the adding quantity of BBHP from 10% to 12%. At the same time, the mechanical properties and color can satisfy the requirement of TPU.
