Fire and Heat Retardant Polymer Materials and Coatings with Functionally Active Phosphorus–Boron–Nitrogen-Containing Components

Novel phosphorus–boron–nitrogen-containing products have been developed that promote intumescing and charring of polymer compositions exposed to flame and enhance their fire and heat protective and adhesive characteristics. The structure of these products has been studied, and their fabrication conditions and basic properties have been determined. The results of research and development of a number of fire-and-heat retardant materials, in particular, rubber protection coatings based on polychloroprene and chlorosulfonated polyethylene and perchlorovinyl resin-based protective coatings for fiberglass and elastomeric materials, are summarized. The possibility of using phosphorus–boron–nitrogen-containing products as sizing agents for fillers, such as microfibers and microspheres, is described.
