摘要

以 P-C-N（聚磷酸铵 APP、季戊四醇 PER、三聚氰胺 MEL 组成）为膨胀体系的钢结构防火涂料应用广泛，但普遍存在耐水性差、防火抑烟效果达不到预期等问题。以 P-C-N 膨胀体系的优化及发展为主线，梳理和总结了膨胀型钢结构防火涂料相关研究。发现通过对膨胀体系中亲水性组分的改性来优化 P-C-N 膨胀体系、在防火涂料中添加碳材料、过渡金属化合物等填料，可协同提高防火涂料性能并取得了较好的效果。然而，这些研究仍未能很好地解决防火涂料环境耐久性及高效防火的发展要求，因此开发新的膨胀体系已成为当前研究的需求与热点。

Abstract

Fire retardant coatings for steel structure with P-C-N (composed of ammonium polyphosphate APP, pentaerythritol PER, and melamine MEL) as the expansion system are widely used, but there are common problems such as poor water resistance and unsatisfactory fire and smoke suppression effects. This article took the optimization and development of P-C-N intumescent system as the main line, and sorted out and summarized the relevant research on intumescent fire retardant coatings for steel structure. It was found that optimizing the P-C-N expansion system through hydrophilic components and adding fillers such as carbon materials and transition metal compounds to the fire retardant coatings had achieved good results in synergistically improving the performance of the fire retardant coatings. However, the fire retardant coatings still could not be solved well. With the development requirements of environmental durability and efficient fire protection, the development of new expansion systems had become a current research hotspot.
