• thermal protection
• chemically grafted polychloroprene
• nanodispersions

The paper presents the results of investigations carried out to obtain some environmentally friendly materials for thermal protection and insulation intended to be used in the manufacture of air-tight packings, membranes, sleeves, protective cases and curtains, protective equipment for high temperature and fire hazard areas. Such materials were made from a fireproofed textile support and a covering polymer material. The textile support was a fireproof fabric of a variety of textures and thicknesses obtained from heat-resistant acryl fibres. Heat-resistant elastomer compounds such as chloroprene compounded with HAP carbon black and antimony chloride were used as covering materials. High performance environmentally friendly aqueous nanodispersions for coating fireproof textiles were obtained by improving the polychloroprene adherence by chemical grafting of polychloroprene latex Dispercoll C 84 with methyl methacrylate in the presence of benzoyl peroxide as initiator. The resulting non-asbestos materials are heat and chemical-resistant, and fireproof.
