RESEARCH OF FEATURES AND COMPOSITIONS OF VERMICULITE FOR USE AS SUSPENSION FIRE RETARDANT FOR TEXTILE MATERIALS

This article presents studies of fire resistance in the treatment of expanded vermiculite, which depends on the size of the dispersed particles and the orientation of the granules, their moisture and temperature. It has been studied that one of the interesting and important in practice properties of vermiculite is its ability to swell and turn into a lightweight effective material for imparting fire resistance. The properties and compositions of vermiculite from the Tebinbulak deposit are studied, from which a flame-retardant suspension is prepared for processing textile materials based on vermiculite dissolved in orthophosphoric acid and alkali in an aqueous medium. When modifying materials with developed flame-retardant suspensions, it is possible to obtain fire-resistant textile materials that meet the requirements of GOST for fire resistance, smoke generation and other physical and mechanical properties.
