The influence of components of fire retardant 
coating on fire resistance performance 
of steel structure

Abstract

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.

Key words: orthogonal analysis, steel structure, fireproof coatings, fire resistance
