Modern polymer materials used in construction, transport and household products characterized, as a rule, by high flammability and combustibility, which has a significant impact on ensuring the required level of fire protection. A variant of the formalization of the choice of a flame retardant coating is proposed and an algorithm for its justification is proposed. The proposed algorithm for choosing a fire-retardant coating assumes a preliminary quantitative assessment of fire danger; analysis of possible scenarios of fire development; the choice of the type of fire protection system taking into account the operating environment, the size of potential damage from fire, technical, economic and human factors, and the rationale for choosing a fire-resistant coating that provides the specified (required) level of fire protection.

Introduction. One of the ways to reduce the fire hazard at industrial facilities is the application of intumescent coatings. It is known that intumescent compositions are multicomponent composite materials, whose effectiveness is due to complex chemical transformations of the components of the studied flame retardant exposed to high temperatures. In this regard, the problem of studying the physicochemical processes and thermophysical characteristics of flame retardant thermal expansion materials is in demand and relevant.The purpose of this article is to analyze the thermophysical properties of water- and acrylic compound-based intumescent flame retardants to improve the safety of oil and gas facilities.To accomplish this purpose, the following objectives were attained:studying acrylic dispersion-based intumescent flame retardant materials using methods of thermal analysis;analyzing aqueous dispersion-based intumescent flame retardant materials using methods of thermal analysis;making a comparative analysis of the thermo-oxidative degradation of the studied flame retardant materials.Methods. During the study, thermogravimetric analysis, differential thermogravimetric analysis, differential scanning calorimetry, and quadrupole mass spectrometry were chosen as the main methods.Results. As a result of the studies performed using methods of synchronous thermal analysis of water- and acrylic compound-based intumescent flame retardants, the similarity of ongoing physicochemical processes was identified, including the presence of four main stages of mass loss and a high exothermic effect. This high thermal effect has proven high flammability of the studied flame retardant materials.Conclusions. Following the analysis, the authors have concluded that intumescent flame retardants, containing acrylic vinyl acetate emulsion and aqueous dispersion, begin to lose their performance characteristics, necessary for a flame retardant material, when the temperature reaches approximately ~600 °C.

Functionally Active Microheterogeneous Systems for Elastomer Fire- and Heat-Protective Materials

Elastomeric materials are utilized for the short-term protection of products and structures operating under extreme conditions in the aerospace, marine, and oil and gas industries. This research aims to study the influence of functionally active structures on the physical, mechanical, thermophysical, and fire- and heat-protective characteristics of elastomer compositions. The physical and mechanical properties of elastomer samples were determined using Shimazu AG-Xplus, while morphological research into microheterogeneous systems and coke structures was carried out on a scanning electronic microscope, Versa 3D. Differential thermal and thermogravimetric analyses of the samples were conducted on derivatograph Q-1500D. The presence of aluminosilicate microspheres, carbon microfibers, and a phosphor–nitrogen–organic modifier as part of the aforementioned structures contributes to the appearance of a synergetic effect, which results in an increase in the heat-protective properties of a material due to the enhancement in coke strength and intensification of material carbonization processes. The results indicate an 8–17% increase in the heating time of the unheated surface of a sample and a decrease in its linear burning speed by 6–17% compared to known analogues. In conclusion, microspheres compensate for the negative impact of microfibers on the density and thermal conductivity of a composition.
