以苯酚与六氯环三磷腈为原料,氢氧化钠为催化剂,在四氢呋喃溶剂中直接合成了环三磷腈的苯酚取代物,避免了金属钠或NaH的使用,合成工艺简便而安全。将所合成的酚氧基环三磷腈与氢氧化镁复配用于聚烯烃弹性体的阻燃。结果表明,所合成的磷腈衍生物与氢氧化镁具有良好的协同阻燃作用,当体系中氢氧化镁的质量分数为48%,酚氧基环三磷腈质量分数为2%时,共混物的限氧指数达到36%,具有良好的阻燃效果。 Using phenol and hexachlorocyclotriphosphazene as raw materials and sodium hydroxide as catalyst, the phenol substitute of cyclotriphosphazene is directly synthesized in tetrahydrofuran solvent to avoid the use of metal sodium or NaH, and the synthesis process is simple and safe. The synthesized phenoxycyclotriphosphazene and magnesium hydroxide compound used in polyolefin elastomer flame retardant. The results showed that the synthesized phosphazene derivatives and magnesium hydroxide have a good synergistic flame retardant effect. When the mass fraction of magnesium hydroxide in the system is 48% and the content of phenoxy cyclotriphosphazene is 2% Oxygen limit index of 36%, with good flame retardant effect.
