中文摘要: |
文从改性聚氨酯泡沫塑料(PU)着手,合成了2,4,6-三酚氧基-2,4,6-三(羟基乙氧基)环三磷腈(Ⅱ),探索了各步的分离提纯方法,鉴定了化合物的结构。实验结果表明,化合物Ⅱ可与异氰酸酯发生反应,当化合物Ⅱ加到聚氨酯泡沫塑料中时,可提高PU的阻燃性能,当含磷量为1.5-2.0%时,可得到自熄性的聚氨酯泡沫塑料。 |
英文摘要: |
Triphenoxy-2、4、6-Tri(hydyoxyethoxy) cyclotriphozphazene(Ⅱ)was synthesized in view of the flame retarding modification of polyurethane.Its separation and purification has been studied arid its structure has been idenfied.It was shown that compound Ⅱcould react with isocynanate(such as TDI).When compound Ⅱwas added to polyurethane(PU),Flame retarding property of polyurethane was improved.Selfxtinguished polyurethane foams in which the content of phorphorus reached 1.5-2.0% were obtained by grafted PU with the compound Ⅱ |
