摘要
以嘧胺、甲醛、三氯氧磷和氧化乙烯类化合物为主要原料，合成出含有三嗪环和环状磷酸酯结构的新型阻燃聚醚多元醇，ＩＲ 谱图证实了其结构。用此阻燃聚醚多元醇与ＴＤＩ通过一步法发泡工艺制成，分子结构型阻燃聚氨酯泡沫塑料，对其配方及性能进行了测试研究，最大极限氧指数达２９．３ ，拉伸强度０．５６ＭＰａ ，伸长率１５８ ％ ，密度３５ｋｇ／ｍ２ ，该软泡沫塑料避免了添加型阻燃软泡沫塑料存在的稳定性差，阻燃剂分布不均等弊病，而且发泡工艺简单，设备投资少，易于操作管理。
s A new flame retardant compound of polyether polyol was synthesized from melamine formaldehyde,phosphorus oxychlorid and compound with epoxy structure,and the chemical structure was proved by IR spectrum.This polyether polyol was formed with polyisocyanate,water and catalyst by one step method,producing a new structural fire resistant PU soft foam.The effects of various prescription and product property were investigated.The soft PU foam material with good fire retardancy,the limited oxygen index(LOI) is 29.3 ,tensile strength 0.56 MPa,elongation rate 158,density 35 kg/m 3.Meanwhile,the flame retardant mechanism of the former materials was discussed.
