摘　　要：自修复聚合物以其优异的性能和丰富的产品形态在现代社会得到了广泛的应用。然而,高可燃性是大部分聚合物的一个普遍缺点。本文从聚氨酯的自修复以及阻燃两方面出发,进行了全面的综述。聚氨酯的阻燃机制通常是通过在自修复聚氨酯中添加阻燃剂来实现的。阻燃剂分为添加型和反应型,添加型阻燃剂是通过阻碍分子链的运动来提高其耐热性,反应型阻燃剂则是通过改变分子结构来提升耐热性能。Self-healing polymers have been widely used in modern society for their excellent properties and abundant product forms.However,high flammability is a common shortcoming of most polymers.The self-healing and flame retardancy of polyurethane are reviewed in this paper.The flame retardancy mechanism of polyurethane is usually realized by adding flame retardants into self-healing polyurethane.Flame retardants are divided into additive type and reactive type.Additive flame retardants improve their heat resistance by blocking the movement of molecular chains,while reactive flame retardants improve their heat resistance by changing the molecular structure.
