摘要：

Intumescent coatings, mainly composed of ammonium polyphosphate, pentaerythritol and melamine, are widely used in the field of fire protection of steel structures. The objective of this study was to investigate how the presence of two different inorganic fillers (titanium dioxide and mineral fibres) will affect the fire performance of an acrylic-based intumescent coating. In both cases, it was observed that the inorganic filler enabled improvement of the fire-protective behaviour of intumescent paints, maintaining their performance for a longer time. The mode of action was attributed to reinforcement of the char due to the presence of the fillers.
