Abstract

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 1015 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.
