摘　　要：采用聚醚多元醇、聚酯多元醇、泡沫稳定剂、催化剂、阻燃剂、发泡剂和耐水解阻燃剂等原材料,通过一步法制备高阻燃喷涂硬泡聚氨酯保温材料(RPUF)。研究了多元醇用量及配比、催化剂体系、阻燃剂体系、发泡剂用量对RPUF性能的影响。结果表明,以100份多元醇为基准,其他组分不变,当聚醚DD-4110、NT-403A和聚酯PS-3152的添加量分别为70份、5份、25份,催化剂Am-1、A-33和TEA添加量分别为4.0份、5.0份、20.0份,TCEP和DMMP添加量分别15份、20份,HCFC-141b添加量为31份时,制得的高阻燃喷涂RPUF综合性能最佳。The high tame retardant rigid polyurethane foam （RPUF） is prepared by one step technique with polyether polyols, polyester polyols, foam stabilizers, catalysts, flame retardants, foaming agents, hydrolysis resistant flame retardants and so on. The influences of the amounts of polyols, catalysts system, flame retardants system and foaming agents on the performances of RPUF are studied. The results showed that the best combination properties are obtained when polyols DD- 4110/NT-403A/PS-3152=70/5/25, catalysts Am-1/A-33/TEA=4/5/20, flame retardants CEP/DMMP=15/20,and the amount of foaming agent HCFC-141b is 31 phr, based on 100 parts of polyols.
