摘要： 为了研究钢结构防火涂料中各组分对耐火性能的影响，通过SPSS软件对溶剂型膨胀性钢结构防火涂料的各个组分设计了正交试验，并通过模拟大板燃烧对不同配比防火涂料的耐火极限进行了试验。试验结果表明，膨胀炭层的致密性和耐烧蚀性对耐火性能影响更为重要。分析得出影响该体系防火涂料耐火性能的各组分顺序为：钛白粉>聚磷酸铵>季戊四醇>三聚氰胺>丙烯酸树脂。通过SPSS正交试验数据分析得到最优配方比例为聚磷酸铵∶季戊四醇∶三聚氰胺∶钛白粉∶丙烯酸树脂=500∶200∶225∶200∶220。 关键词：正交分析；钢结构；防火涂料；耐火性能

Abstract: The orthographic test was designed on the various components of solvent-based expansion steel structure fire retardant coating through SPSS software, and the fire resistance limit of different matching fireproof coatings is tested by simulating large plate combustion experiment, and the fire resistance of fire retardant coatings affecting the system is reached by data analysis. The order of the various parts of fire performance is as follows: titanium white powder > ammonium polyphosphate > glutamol > amide > acrylic resin, and the influence of titanium white powder is more obvious than other factors. At the same time, through the analysis of SPSS orthographic test data, the optimal formula ratio is ammonium polyphosphate:triamcinol:melamine:titanium white powder:acrylic resin=500:200:225:200:220.
