Prospects and Development of Research of Composite Elastomer Materials

Abstract

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

Multifunctional ingredients for composite elastomer materials

“…The higher the frequency, i.e. the shorter the exposure time, the higher will be the glass transition temperature of the plasticized system [1][2][3][4][5][6][7][8][9][10][11][12][13].  OFF-oligomer from furfural, OTHFS-oligomer of tetrahydrofurfuryl alcohol, OFFSoligomer from furfuryl alcohol.…”

“…Thus, the use of furan oligomers as plasticizers for elastomer compositions has shown that, being a product of a multifunctional action, they exhibit high plasticizing properties, while increasing the stickiness of rubber compounds and the strength properties of rubber. It has also been established that they significantly activate the process of both sulfuric and thiuramic vulcanization [12][13][14].…”

“…10-4 s-1 for technical rubber, which indicates its great influence on side reactions to inhibit the oxidation of elastomers. Studies of the thermal aging of composites stabilized with furan oligomers have shown that with an increase in the duration of aging time, a decrease in the relative elongation of the composites is observed, compared with samples stabilized with neazone D. Apparently, in the process of thermal exposure under the action of furan units, additional structuring occurs due to which leads to an increase in rigidity and a decrease in the values of relative elongation of composites [9][10][11][12][13][14][15].…”

New ways of processing and application of the croton fraction of waste from the production of JSC “Navoiazot”

“…Before the discovery of the vulcanization process, the use of rubber was limited. It can be argued that only thanks to the discovery of vulcanization rubber has become a technically valuable material [1][2][3].…”

Modification of dispersed systems and its effect of the internal corrosion of hydrotransports

“…The essence of this process is determined by the peculiarities of dispersed systems, primarily, the particle size composition of solid particles and their volume concentration. The mutual influence of fluid and solid particles during their joint movement is detected by the wear of the pipeline materials, a kind of pressure loss and the determination of the bearing stream capacity [5][6][7][8][9]. The particle size distribution composition of solid particles of dispersed systems, as well as their concentration and modification, have an influence as a change in the average flow rate and as a result of the change in the hydraulic and energy parameters of the pressure system [4][5][6][7][8][9][10][11][12].…”
