摘要 随着人们环保意识的不断提高,卤系阻燃剂的毒性问题受到越来越多的关注,阻燃剂无卤化已经成为必然趋势。间苯二酚双(二苯基磷酸酯)齐聚物(RDP)阻燃剂是一种无卤添加型阻燃剂,因具有优异的热稳定性和低挥发性而得到广泛应用。实验中分别用它与膨胀石墨来阻燃高回弹聚氨酯软泡并进行了二者协同阻燃聚氨酯软泡的研究。用氧指数仪和民航飞机用垂直燃烧方法测试表征了制备的泡沫样品,并对其阻燃性能进行了研究。 With increasing ecological and environmental concerns, the use of halogenated flame-retardants are being limited and halogen-free alternatives will be developed rapidly. Resorcinol bis (diphenyl phosphate) (RDP) is a non-halogen aromatic oligomeric phosphate flame-retardant and flow modifier. Its high thermal stability and low volatility make it ideal for use in applications where high processing temperatures are required. In this paper, RDP was used as a single flame retardant of resilience polyurethane foam, and used together with exfoliated graphite (EG) as synergistic flame retardant. The limited oxygen index (LOI) of foam specimen was tested according to the GB 2406-80 standard and vertical flammability was tested in terms of CCAR25.853 (b) Flammability Teat Method.
