Effect of content of synthetic aluminosilicates in medium-density polyethylene on the fire hazard characteristics and mechanical properties of compositions is investigated. It has been shown that during decomposition of the filler with the release of water, its effectiveness depends not only on the endothermic effect of decomposition and the content of dehydration products, but also on the correspondence of temperature of the dehydration of the filler and the temperature of intensive decomposition of the polymer. Regardless of the type of fillers, an increase in their content in polymer composite material helps to reduce combustibility. It has been shown that compositions based on epoxy oligomers or medium-density polyethylene and synthetic zeolite have properties of self-extinguish and fairly high physical and mechanical characteristics. It is shown that epoxy polymer composite material with the content of inorganic fillers 40-70 wt.% can be used for sealing building structures and other products operating at elevated temperatures, as well as in a mode where the fire resistance and heat resistance of the sealing compound are decisive. A number of efficiency of flame-suppressing of fillers is presented. Formulations of compositions based on epoxy oligomers or medium-density polyethylene whith synthetic zeolite having an optimal ratio of fire hazard and mechanical properties and not having toxic or carcinogenic effects when heated are recommended.

“…Experimental studies of borosilicate face many difficulties due to volatilization of B 2 O 3 at high temperatures,the high viscosity of borosilicate melts resisting their tendency for crystallization and the high melting temperature of 1921 K [18,21,22]. The melting temperature of AS2 is about 2113 K [23]; 2141 K 15 K [24]. Therefore, experiment investigations at high temperature or pressure for AS2 are usually difficult to do.…”

The network structure of B2O3-2SiO2 and Al2O3-2SiO2 systems (abbreviated as BS2 and AS2, respectively) in the liquid state is investigated by molecular dynamics simulation. For the BS2 system, most of the basic structural units are BO3 and SiO4. The number of BO4 and SíOb is very small. Most of the tetrahedral SiO4 and trigonal BO3 networks link to each other via mainly the corner-sharing bonds to form -Si-O-Si- and -Si-O-B- linkages. For the AS2 system, most of basic structural units are tetrahedral TO4 (T=Al, Si) and trigonal AlO3. The number of TO5 is negligible. The basic structural units link to each other through mainly the corner-sharing bonds to form -Si-O-Si- and -Si-O-Al- linkages. The topology of basic structural units is investigated via the bond angle and length distribution. The addition of Al2O3 or B2O3 into silica results in the change of the -Si-O- network structure. The cation B3+ or Al3+ tend to replace the Si 4+ in the tetrahedra SiO4 to form negative charge units [BO 4]- and [AlO 4]-, respectively. The concentration of negative charge units in the network structure of AS2 and BS2 is different. The network structure is studied through linkages T-O-T (T = Si, B, Al) and the number of types of linkages. Especially, the structural heterogeneity is also presented and discussed in detail. The structural heterogeneity in BS2 and AS2 liquids is due to the coexistence of two BO3 and SiO4 structural phases in BS2 and three SiO4, AlO4 and AlO3 structural phases in AS2 liquids.
