摘要
根据所含阻燃元素的不同,聚氨酯硬泡用阻燃多元醇大致可分为磷系阻燃多元醇、卤系阻燃多元醇、复合型阻燃多元醇及芳杂环类阻燃多元醇等。本文对各种类型多元醇的制备路线进行了总结,并介绍了几种具有代表性的合成方法。
Flame resistant polyols used in rigid polyurethane foams are divided into several types due to the flame retardant elements in the molecules, such as phosphorus polyols, halogen containing polyols, complex flame resistant polyols and aromatic/heterocyclic polyols. In this article, an overview of flame resistant polyols is given, and also the typical synthetic routes.
