This work is devoted to study of halide mechanochemical modification of nitrile-butadiene rubber (BNCS-18AN) with a chlorine-containing reagent. In previous studies, the optimal parameters for modification were established. The modification was carried out in a laboratory rubber mixer. The obtained halogen-containing rubbers were investigated using ESR spectroscopy. Rubber compounds based on obtained chlorinated butadiene-nitrile rubbers (CNBR), were prepared and their tensile stress-strain properties and curing characteristics were investigated. Vulcanization of rubber compounds was carried out under the established optimal conditions. Physical and mechanical properties of the rubbers were determined. Subsequent studies showed the most probable regularities of the mechanochemical halide modification of nitrile butadiene rubber (BNCS-18AN) with a chlorine-containing modifier (CHCl) in a rubber mixer.

The acid–base balance of the surface of silica filler (SF) particles of different grades was determined, and its influence on the structure and properties of mixes based on nitrile butadiene rubber (NBR) was investigated. A near-linear correlation was found between the proneness of the SF particles to flocculate and the concentration of acid centres (ACs) on their surface, in the absence of any pronounced influence on this index of the degree of dispersion of the filler particles. Of all the SF grades investigated, the greatest capacity to form flocculation structures is exhibited by a filler characterised by a higher SF concentration. Increase in the SF concentration leads to an increase in the relative content of physical and covalent bonds in binary mixes of NBR and SF. It is shown that, to reduce the negative effects associated with the formation of flocculation structures, including in the induction period of vulcanisation, it is necessary to select a filler with a lower concentration of these centres.

Penelitian ini untuk mengetahui pengaruh penambahan Natural Rubber (NR) dan Epoxidation Natural Rubber (ENR-46) dengan kompatibiliser Chlorprene Rubber (CR) pada aplikasi kompon termoplastik Poly Vinyl Chloride (PVC) dan Nitrile Butadiene Rubber (NBR), variabel penelitian meliputi ENR-46/PVC/NBR/CR, NR/PVC/NBR/CR dan CR-NR/PVC/NBR, CR-ENR-46/PVC/NBR. Parameter pengujian sifat fisik-mekanik : Hardness (Shore A), Tensile Strength (Mpa), Elongation at Break (%) dan ketahanan terhadap pelarut minyak (n-Pentane, Toluene, Hexane dan Pertalite). Hasil penelitian didapatkan untuk sifat fisik-mekanik, semakin banyak penambahan NR Kekerasan kompon termoplastik akan menurun, Tensile Strength dan Elongation at Break kompon akan meningkat begitu juga dengan CR-NR. Tetapi berbanding terbalik hasilnya untuk ENR-46 dan CR-ENR-46. Pengujian Ketahanan terhadap pelarut minyak semakin banyak penambahan ENR-46 Ketahanan kompon termoplastik terhadap pelarut akan meningkat, hasil yang sama juga pada CR-ENR-46. Tetapi berbanding terbalik hasilnya dengan penambahan NR dan CR-NR pada kompon termoplastik.

The results of study of the influence of hollow corundum microspheres HCM-S (5–100 µm) and HCM-L (70–180 µm) on the properties of nitrile butadiene rubber BNKS-18 are presented. The dependence of elastomer resistance to abrasion impact and physic and mechanical properties on the dispersion and concentration of hollow corundum microspheres is shown. The process of hollow corundum microspheres exfoliation of the elastomeric matrix, which largely determines the change of physic and mechanical properties, has been studied by specially developed stretching device compatible with an atomic force microscope. The paper describes microspheres exfoliation which is conventionally divided into 3 stages.
