XPS, EPS and PU are organic insulation materials with the efficient insulation characteristics whose fire performance can only reach B2 level. New decorative insulation materials XRY was developed and the structure of it was introduced. The insulation core material of decorative hoard was sealed at 6 surfaces to avoid the touching of fire. The fireproof of XRY reached A level from test, and the XRY has features of energy-saving and execution convenient. The application showed that the performance of it is good.%有机质绝热材料XPS、EPS和PU等具有高效保温的特点,但其防火性能最高只能达到B2级.研制新型装饰保温材料XRY,介绍其构造及结构特点.装饰板对保温芯材进行六面全封闭,避开与火源接触的机会.经测试该材料防火性能可达A级,具有节能、防火施工便捷的特点.实际应用表明其综和性能优异.
