本征阻燃聚氨酯弹性体制备及其性能研究
Preparation and Performance Study of Intrinsically Flame Retardant Polyurethane Elastomer
摘要
Abstract
In the study,a highly efficient reactive flame retardant polyether polyol was synthesized by one-pot method using a commercial bimetallic cyanide(DMC)catalyst.The effects of design molecular weight and other parameters on the polymerization activity of flame retardant polyether polyols were studied.The intrinsic flame retardant polyurethane elastomer(FR-PU)was further prepared by using flame retardant polyether polyol as flame retardant carrier.Unlike traditional flame retardants that reduce the mechanical properties of the material,the mechanical properties of the intrinsic flame retardant polyurethane elastomer prepared by the reactive flame retardant polyether were not significantly reduced.The thermal stability and flame retardant mechanism of FR-PU were studied by thermogravimetric analysis and cone calorimeter,respectively.The results showed that the heat release rate(HRR)and total heat release(THR)of polyurethane elastomer both decreased by about 40%when the addition mass fraction of flame retardant polyether in the total formula of polyether increased to 20%,and the gas phase and condensed phase flame retardant worked together.The method provides a new strategy for the development of flame retardant polyurethane materials.关键词
