钢结构防腐防火一体化涂层技术研究

摘要

在现代建筑工程中，钢结构因其高强度和施工便捷性被广泛应用，但其易腐蚀和耐火性差的问题严重影响结构安全与使用寿命。本文围绕“钢结构防腐防火一体化涂层技术”展开研究，旨在提出一种能够同时满足防腐与防火双重功能的新型涂层体系。通过分析现有涂层材料的性能缺陷，结合实验数据对比不同复合涂层的防护效果，探讨材料配比、涂覆工艺及环境适应性对涂层综合性能的影响。采用有机-无机复合基料并添加多功能助剂的一体化涂层，在提升耐腐蚀性和耐火极限方面具有显著优势，可为钢结构长效防护提供新思路。

Abstract

In modern construction engineering, steel structures are widely used due to their high strength and construction convenience. However, problems such as easy corrosion and poor fire resistance seriously affect structural safety and service life. This paper focuses on the research of "integrated coating technology for anti-corrosion and fire protection of steel structures," aiming to propose a new coating system that can simultaneously meet the dual functions of anti-corrosion and fire protection. By analyzing the performance defects of existing coating materials, comparing the protective effects of different composite coatings with experimental data, the influences of material ratio, coating process, and environmental adaptability on the comprehensive properties of the coatings are discussed. The integrated coating using organic-inorganic composite base materials and added multifunctional additives has significant advantages in improving corrosion resistance and fire resistance limit, which can provide new ideas for the long-term protection of steel structures.
