The study presents the results of the composition development for producing heat-insulating fire-resistant coating for concrete and metal surfaces of various construction facilities. The composition includes binder - siloxane rubber, filler - hollow carbon microspheres, and flame retardant additive – electroplating sludge. Siloxane rubber improves heat-insulating properties of the obtained coating. Hollow carbon microspheres used as fillers in the amount of 20-50 wt.p. decrease heat insulation of the coating. Flame retardant additive in the amount of 10-15 wt.p. provides self-extinction effect to the cured coating. The study demonstrates that hollow carbon microspheres characterized by low heat insulation ratio are much more effective as compared to the glass or ceramic microspheres. Besides, they provide high strength and low specific weight due to their valuable physical and chemical properties. Metals hydroxides and oxides contained in the electroplating sludge serve as flame retardants in the polymer heat insulating coating, and effectiveness of their activity is directly proportional to their content in the composition, but the increase of galvanic sludge over 15% is undesirable, as the composition viscosity increases physical and mechanical properties of polymer coating. The study demonstrates that siloxane resin based composition filled with hollow carbon microspheres and containing flame retardant additive of galvanic sludge facilitates producing comparatively cheap but rather effective construction polymer coatings with good heat-insulating and fire resistant characteristics.
