【摘要】 本文合成了三（２，３－二溴丙基）磷酸酯和聚磷酸锭等阻燃剂。利用正交设计方法研究了阻燃聚氨酯泡沫塑料配方。实验结果表明阻燃聚氨酯泡沫塑料水平燃烧速度为０．０１２ｃｍ／ｓ。阻燃聚氨酯泡沫塑料的氧指数为２６。更多还原

【Abstract】 This paper synthesized the flame retardant agents of tri(2,3-dibromo-propyl)phosphate and ammonium polyphosphate,etc. Formulas of flame retardant polyurethanefoaming plastics were studied by orthogonal plan method.The experimental resultsshown that the horizontal burning rate and the oxygen-index of fire retardantpolyurethane foaming plastics were 0. 012cm/s and 26,respectively.更多还原
