磷酸酯类无色透明阻燃剂的研究

Study on Colorless Transparent Phosphoric Ester Fire Re-tardant

磷酸酯类阻燃剂系由胺类、磷酸和甲醛缩聚制得,可合成为固态或液态阻燃剂,分别用于各种高分子聚合物或木制品等的阻燃。对磷酸酯类阻燃剂的生产工艺进行了研究,并简述了其阻燃机理及应用情况。

Phosphoric ester fire retardant is made from ammo-nia,phosphoric acid and formaldehyde,and can be synthesized into liquid or solid fire retardant,which can respectively used for retarding combustion of different k inds of polymer or wooden products.This paper describes the p roductive technology of the phosphoric ester fire retardant,its fire -retardant mechanism and application.
