Research of Thermal Stability and Fire-Resistance Properties of the Composite Material “Water Glass-Graphite Microparticles”

Abstract:

The properties of “water glass – graphite microparticles” composite material (CM) have been researched and qualitative and quantitative phase analysis of the CM structure has been done. Experimental samples of the CM with filler particles (graphite) and a few micrometers in size have been studied with X–ray diffraction and electron microscopy. Fire–resistance test of the composition has been conducted. Fire–resistance limit for the test samples of composite material is determined by the loss of its insulating ability (I). Fire–resistance limit I15 equal to 15 minutes has been obtained in accordance with the requirements of regulatory documents. It is shown that the research material is characterized by thermal stability and maintains its composition and structure under high temperature exposure. Composite material with the obtained characteristics can be used as protective coatings for building structures to increase fire resistance and reduce fire hazard.
