Abstract
An intumescent fireproofing formulation on silicone base, modified with mineral components (calcium carbonate, wollastonite, aluminosilicate microspheres), was studied by synchronous thermal analysis (Netzsch SТА 449 F5 Jupiter®). Introduction of 2–20 wt % wollastonite or aluminosilicate microspheres enhances the heat resistance (the ash residue increases by 27–40%) and reduces the combustibility of the modified fireproofing formulations (the total thermal effect of thermolysis of the fireproofing formulation decreases by a factor of more than 3). The optimum content of wollastonite and aluminosilicate microspheres is 5 wt %. Addition of calcium carbonate gave no complex positive effect.
