摘　　要：考察了阻燃聚醚多元醇ZR–001对聚氨酯高回弹泡沫性能的影响。实验表明,随ZR–001添加量增多,泡沫硬度和强度逐渐提高,同时泡沫回弹性下降,压缩永久变形和甲醛含量增大。当ZR–001在A组分中添加质量分数为50%时,高回弹泡沫的75%压缩永久变形超过10%;ZR–001在T/M[TDI（甲苯二异氰酸酯）/MDI（二苯基甲烷二异氰酸酯）]体系泡沫中的阻燃效果优于在MDI体系泡沫中的,在T/M体系泡沫中,当A组分中添加ZR–001质量分数为70%时泡沫的氧指数可达到24.2%。The influence of the flame retarding polyether polyol ZR-O01 on the performance of the polyurethane high resilience foam was investigated. The experiments show that with increase of ZR-001 adding amount, the hardness and strength of the foam gradually increase, its resilience property decreases, the compression set and the formaldehyde content increase. When adding mass fraction 50% ZR-001 in A component, the 75% compressive set of the high resilience foam exceeds 10%. The flame retarding effect of ZR-001 in the T/M [TDI （toluene diisocyanate）/MDI （diphenylmethane diisocyanate）] system foam is superior to that in the MDI system foam. In the T/M system foam, the oxygen index of the foam can reach 24.2% when adding mass fraction 70% ZR-001 in A component.
