摘　　要：采用实验所得的最佳全水发泡工艺,制备了ODP值为零的硬质聚氨酯泡沫塑料(RPUF),其压缩强度满足GB10800-89《建筑物隔热用硬质聚氨酯泡沫材料》的要求。在此工艺下,以季戊四醇螺环磷酸(SP-DPA)为阻燃剂制备了无卤阻燃RPUF,讨论了SPDPA含量对RPUF性能的影响。SEM和耐水溶性测试表明SPDPA与RPUF基体有良好的相容性。当SPDPA的添加质量份数为30份时,RPUF的氧指数达到26.0,能达到UL-94 V-0阻燃级别。TGA测试表明阻燃RPUF有良好的成炭能力,SEM证明了燃烧后的RPUF表面能形成非常致密的炭层。SPDPA的加入对RPUF的力学性能影响较小,当SPDPA添加质量份数为30份时,其压缩强度仍能满足GB10800-89的要求。A water blown RPUF, the ODP equal to zero, was prepared by the best research technology. The compression strength of the RPUF reached the requirements of GB10800-89. The halogen free flame retardant RPUFs were prepared with SPDPA as flame retardant by the foaming technology and the performance of flame retardant RPUFs with different addition of SPDPA was discussed. SEM shows SPDPA can be evenly dispersed in RPUF matrix, the water resistance test shows the SPDPA can exist in the RPUF matrix stably, the above results confirm there is a favorable compatibility between SPDPA and RPUF. Flame retardant test indicates the LOI of the RPUF-SPDPA（30） is 26.0 and UL-94 V-0 rating can be reached. TGA shows RPUF-SPDPA（30） has a high yield of residual char at high temperatures. The compact charred layers can be seen in the surface of the char by SEM. When the phr of SPDPA is 30, the compression strength of the flame retardant RPUF still reaches the requirement of GB10800-89.
