The paper investigates the physical and chemical properties of the carbon-containing material of the secondary raw material for the production of acetylene and its effect on the radiation resistance of rubber products and cable rubbers. It was found that the carbon-containing material is modified carbon, the surface of which is microencapsulated with oligomeric oxygen-containing compounds, its thickness, calculated from the value of the specific geometric surface, amounted to 50-60Å. The effect of carbon-containing material on the relaxation coefficient and compressive stress is shown, and radiation resistance by the relative elongation of rubbers in an ionizing radiation environment 60Co. At the same time, it was found that, due to the finished oligomer on the surface of particles of carbon-containing material, threshold dose of radiation of rubbers based on styrene butadiene rubber according to the relaxation index, compressive stress and the coefficient of radiation resistance in terms of relative elongation increases three times compared to carbon blacks P803. Similarly, dependencies were obtained in rubbers based on other types of rubbers, including nitrile butadiene rubbers, possessing low radiation resistance due to the increased tendency to structuring. The findings indicate that the carbon-containing material is an effective filler for increasing the radiation resistance of industrial rubber goods and cables, operated in the environment of ionizing radiation.

The aim of this work is to study the effect of new modified ingredients on the complex of properties of composite elastomeric materials. It was found that the introduction of modified ingredients into the composition of elastomeric compositions enhances interfacial interaction at the «rubber-filler» interface and the formation of additional bonds between rubber macromolecules and functional groups, as a result of which an improvement in the complex of properties of the compositions is observed. The introduction of modified carbon into the composition of elastomeric compositions enhances interfacial interaction at the «rubber-filler» interface and the formation of additional bonds between rubber macromolecules and functional groups of the oligomer, as a result of which an improvement in the complex of properties of the compositions is observed. The technology of purification of mineral fillers from metal oxides has been developed. A sufficiently high degree of purification by this method is due to the fact that in the process of temperature exposure at 950 K, iron ions from the paramagnetic state (d-form Fe2O3) pass into ferromagnetic (r-form Fe3O4). Feasibility and prospects of using modified fillers, both mineral and organic, in the formulations of rubber compounds for the production of various types of rubber products

The purpose of this work is to study the effect of multifunctional ingredients on the complex of properties of composite elastomeric materials. New multifunctional ingredients with stabilizing properties are proposed, and their optimal content in the composition is determined. It is shown that thermal aging of composites stabilized by furan oligomers, with an increase in the duration of aging time, a decrease in the relative elongation of the composites is observed, which, in the process of thermal exposure under the action of furan units, additional structuring occurs.The expediency of using furan oligomers as effective multifunctional ingredients for elastomer compositions has been established, which made it possible to purposefully regulate the structural and physico-mechanical characteristics of the compositions without changing the technology and instrumentation of the existing production.

The aim of the study is to study the effect of gas pyrolysis resin on the properties of elastomeric composite materials. It has been established that in the presence of it in the thiuram vulcanizing system, the relative rate of vulcanization of styrene-butadiene rubber increases, the time to reach the optimum vulcanization decreases, but the degree of vulcanization decreases, proportional to the maximum torque, and when using a sulfur vulcanizing system, it activates the vulcanization process, which is facilitated by the presence in its composition of active functional groups (-OH, -COOH, etc.). It is shown that the tensile strength and relative elongation of the vulcanizates increase, while the elasticity remains at an average level.
