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.

“…The value of the coefficient of thermal conductivity in the temperature range from 20 ° C to 400 ° C is in the range of 0,85-1,2 W/(m•K). The specific heat value in the range from 20 ° C to 400 ° C increases logarithmically from 700 to 1200 J/(kg•K) [14]. By thermogravimetry it was found that at 900 °C the flame retardant CM loses mass and subsequently, over time, collapses due to the melting temperature of one of its components [16].…”

The article presents the results of work aimed at improving the efficiency of forest fire protection machine from forest fires using composite materials. The composition and technology of composite material “water glass – graphite microparticles” production is proposed. It was found that composite material is able to maintain the phase composition and structure at elevated temperatures. Methods of application of fire-retardant composite material on the protected surfaces are considered. The values of limit loads that lead to the destruction of composite material are revealed. A mathematical model was developed and a numerical experiment of high temperatures on composite material was carried out using it as a fire-retardant coating. The resulting composite material can be used as a protective coating for the surfaces of the enclosure of cabins of forest fire machines, building structures. CM can be used as a lining of equipment in the thermal power and metallurgical industries, as well as in equipment used in emergency situations.

Modern construction market is experiencing a shortage of highly efficient thermal insulation materials. Alkali-silicate raw mixtures in combination with high-performance fillers currently make it possible to create porous heat-insulating materials with unique properties: rigid cellular structure, specified geometric dimensions and shape, low thermal conductivity, incombustibility, high processability, environmental friendliness, etc. at a relatively low cost. The use of such heat-insulating materials in construction allows solving the problems of energy saving, accessibility and cost-effectiveness. The article considers possibility of obtaining heat-insulating material based on sodium silicate (silicate glue "Polipax") and natural material -flasks from Taskalinsky deposit of West Kazakhstan region. Technical characteristics of Polypax glue are given. Using a scanning electron microscope, elemental, chemical, and oxide compositions of the flask were studied. A recipe for a heat-insulating composite material (HCM) has been compiled.To assess the quality of the obtained HCM, its physical and mechanical characteristics were determined: density, water resistance, thermal conductivity, strength. Samples I-II in terms of density and strength showed the best results, and samples III-IV differ slightly from the technical conditions in terms of the studied indicators. It has been determined that the obtained HCM using flask as filler has a positive effect on the performance properties of the heat-insulating material, and is also economically viable, because local raw materials are used. Thus, it is possible to use flask from Taskalinsky deposit of West Kazakhstan region as filler for heat-insulating material.
