Abstract
Purpose: The aim of the work is to study the effect of phosphate-containing fire retardant Polyisomat A on the structure and chemical properties of peat-vermiculite heat insulating material and its flammability.
Research findings: Experiments show changes in the morphology, chemical composition, and thermal properties of the samples. It is found that the composition modified with ammonium salts improves the fire resistance and reduces the thermal decomposition rate without a significant degradation of thermal insulation properties. The best concentration of the fire retardant is determined to ensure a balance between the strength and fire safety performance.
Practical implications: The obtained data help to evaluate the effectiveness of the fire retardant in enhancing the fire resistance and performance of peat-vermiculite heat insulating material.
