摘　　要：结构保温板SIP保温性能良好,常用的覆面材料为木质OSB。基于木材资源减少,竹材资源丰富的现状,对分别以木质OSB、重组竹及竹帘胶合板为覆面材料(12 mm)、发泡聚苯乙烯板为芯层(89 mm)的SIP保温性能进行对比。结果表明,木质OSB、重组竹、竹帘胶合板的导热系数差异较大,分别为0.155、0.725、0.504W/(m·K),但以这3种材料覆面的SIP传热系数差异不大,分别为0.405、0.415、0.422 W/(m2·K),三者在稳态条件下均传热均匀。SiP has good heat-retaining properties,which usually faced With wooden OSB panel. As the fact of wood diminishing while bamboo growing fast, heat-retaining properties of SIP faced with wooden OSB,bamboo scrimber, and bamboo plywood （with the thickness of 12 mm） on polystyrene foam panel core （89 mm） were contrasted in this article,and the results show that：difference of thermal conductivities of the three were large [（0.155,0.725,0.504 W/（m ·K） respectively] , while heat transfer coefficient were small [0.405,0.415,0.422 W/（m^2·K） respectively]. Heat was transferred uniformly under steady state all of the three kinds of SIP.
