DEVELOPMENT OF TECHNOLOGY FOR OBTAINING FIREPROOF HEAT INSULATING MATERIALS BASED ON SILICATE-POLYMER COMPOSITIONS
Keywords:Heat insulation material, ignitability, sodium liquid glass, silicone
The research work presents the research results on the technology development for obtaining fireproof tile materials with effective heat insulation properties. The main components used to produce insulating tile materials were readily available raw materials such as standard natrium liquid glass, silicone, hydrochloric acid, epoxy resin, the mineral dolomite and wallastonite, thermovermiculite, as well as other special additives. Based on the work performed, the entire technological cycle of obtaining tile materials has been developed. In the work developed two types of tile material differing in the component composition. The first, tile material with a porous silicate composition and the second tile material, which is derived from, as the main component of thermovermiculite. The technological process weight of obtaining the two types of tile materials consists of several steps. At the first stage of research in the laboratory conditions developed compositions of these materials and then in the next few stages of research developed a full technological cycle of obtaining tile heat-insulating materials. Research samples of tile materials obtained by the developed technology showed that the samples of these materials meet the state standards requirements for physical-mechanical and fire-technical properties.
