摘要
以定向刨花板(OSB)或结构胶合板为面板,聚氨酯保温板为芯板,制备结构用木质保温板(SIPs),探究面板种类和芯板厚度对SIPs力学性能的影响。结果表明:不同材料面板和不同厚度芯板制备的SIPs,力学荷载值均可满足ANSI/APA PRS 610.1-2013标准要求;结构胶合板为面板的SIPs极限荷载值高于OSB面板SIPs;随着芯板厚度的增加,SIPs的极限荷载值逐渐增加;聚氨酯保温板可以替代聚苯乙烯保温板(EPS)制备SIPs。
Wood-based structural insulated panels(SIPs) were prepared with oriented stranded board(OSB) or structural plywood as face panels and polyurethane insulated board as the core board. Mechanical properties of the SIPs were investigated.The results indicated that the mechanical load of the SIPs samples could meet requirements of ANSI/APA PRS 610.1-2013 standard.Ultimate load of the SIPs faced with structural plywood was higher than that faced with OSB.The ultimate load increased with increased thickness of the core board.Polyurethane insulation board could be used to replace polystyrene insulation board(EPS)as core board to prepare SIPs.
