Performance characterization of polyaryloxyphosphazene insulation coating material
摘要
Abstract
Aiming at the performance requirements of thermal insulation material for solid rocket motor,Poly(aryloxyphosp-hazene)based thermal insulation coating materials were prepared.Performances of the Poly(aryloxyphosphazene)thermal insulation coating materials,such as thermal conductivity,linear expansion coefficient,density,linear ablation rate and compatibility with pro-pellant were characterized by using thermal conductivity measuring device , dynamic thermal analysis, SEM and the measuiring methods regulated by military standard.The results show that,the thermal conductivity of polyaryloxyphosphazene is 0.187 W/(m· K),the linear expansion coefficient is 2.31×10-4℃-1,the density is 1.196 g/cm3,the linear ablation rate is 0.109 mm/s,and the layer is hard with high char yield after ablation. The materials present good compatibility with propellant. The poly ( aryloxyphosp-hazene) can be used as thermal insulation coating material for new advanced rocket engines due to its excellent physical properties and anti-erosion ability.关键词
