STUDY OF THE INFLUENCE OF INTUMESCENT FILLERS ON WATER ABSORPTION OF FIREPROOF COATINGS OF METAL STRUCTURES BASED ON ACRYLIC DISPERSION

Abstract

The article presents the main features of the effect of intumescent fillers on the water absorption of fire-resistant coatings for the protection of metal structures based on acrylic dispersion. It is emphasized the importance of developing new fire-resistant coatings for metal structures, which will take into account not only protection against the effects of high temperatures and fire in fire conditions, but also prevent moisture sorption to the protected structures. The article compares the effect of intumescent fillers of the ammonium polyphosphate/pentaerythritol/aluminum hydroxide/styrene-acrylic dispersion system on the water absorption of fire-resistant coatings of metal structures. The obtained results can be used in the development of waterproof fire-resistant coatings for metal structures based on the ammonium polyphosphate/pentaerythritol/aluminum hydroxide/styrene-acrylic dispersion system.
