Abstract: This article has described the testing methods of the performance of fire retardant coatings for steel structure. Combined the practical experience, the principle of formulation design of fire, retardant coatings for steel structures was presented, focusing on the research and application of high build. thin, super-thin and outdoor fire-resistant coatings for steel structures, respectively.

Key words: steel structure buildings, fire - resistant coatings, fire proofing and heat insulation, fire- retardant agents, duration of fire resistance

摘要： 介绍了钢结构防火涂料的性能测试方法,并结合工作实践介绍了钢结构防火涂料的配方设计原则。重点介绍了厚涂型、薄涂型、超薄膨胀型室外型钢结构防火涂料的研究及应用范围。
