高低温交变老化对聚合物基保温材料燃烧性能的影响
The Effect of High-low Temperature Cycle Aging on Combustion Properties of Polymer-based Thermal Insulation Materials
摘要
Abstract
The high-low temperature cycle aging experiments of typical polymer-based thermal insulation materi-als including expanded polystyrene foam ( EPS) ,extruded polystyrene foam ( XPS) and polyisocyanate-polyurethane foam ( PIRPU) were carried out with -20℃ to 50℃ cycle in high-low temperature aging chamber,respectively. The flame retardant elements content of the materials after high-low temperature cycle aging decrease with the in-crease of aging test time while the foam structure of the materials are unchanged,which were analyzed by ion chro-matography and scanning electron microscope. The combustion properties of the materials after high-low tempera-ture cycle aging were investigated by oxygen index and cone calorimeter,the results show that the combustion prop-erties of XPS decrease obviously,the peak values of heat release of EPS increase and high-low temperature cycle ag-ing has few effect on the combustion properties of PIRPU.关键词
