红磷增效Al(OH)_3和Mg(OH)_2阻燃聚丙烯的研究

The Study on Enhancement Effects of Red Phosphorus to Al(OH)_3 and Mg(OH)_2 for Flame Retardation of polypropylene

本文通过氧指数测定和差热分析,研究了红磷对 Al(OH)_3和 Mg(OH)_2阻燃 PP的增效作用。实验結果表明:虽然红磷单独对 PP 的阻燃效果不好,但由于它与Al(OH)_3和 Mg(OH)_2之间对于 PP 具有阻燃协同效应,所以加入少量红磷就能够增强Al(OH)_3和 Mg(OH)_2对于 PP 的阻燃效果。

The enhancing effects of red phosphorus to Al(OH)_3 and Mg(OH)_2 forflame retardation of PP has been examined by oxygen index determination andDTA,The experimental results showed that the red phosphorus alone had lowefficiency to flame retardation for PP.When a little amount of red phospho-rus was added to the system of AI(OH)_3 and Mg(OH)_2,the red phosphoruscould enhanced the effects of flame reardation for PP due to its synergism.
