| Popis: | Purpose. The article is devoted to the development of the method of flame retardant step processing of polyester insulation by chemically fixing non-toxic flame retardants on it through the adhesive sublayer of tin compounds. Methods. Methods of transmission electron microscopy, X-ray photoelectron spectroscopy, gravimetry, GOST fire tests. Findings. It was established that polyester insulation, which underwent step fire-retardant treatment using alcohol solutions of SnCl2 with a high concentration of colloidal particles of dimensions less than 1015 nm, and ammonium metal phosphate flame retardant are characterized by the highest burning resistance category for fabrics. Application field of research. Fire retardant polyester non-woven material can be used in construction as insulation, noise insulator, filler, finishing and construction material. Conclusions. The conditions for the formation of reactive colloidal nano-sized particles in alcohol solutions of tin chloride, which provide a strong binding of a nitrogen-phosphorus-containing inhibitor of combustion to a polyester matrix, are determined. The presence of a chemical interaction of the flame retardant components with the polymer and the adhesive sublayer of tin compounds with the formation of bridge bonds has been proved. |
