Некоторые из перечисленных свойств являются взаимоисключающими и не всегда достижимы в материалах на основе индивидуального каучука. Для создания резин уплотнительного назначения с сочетанием необходимых свойств перспективным может являться использование смесей каучуков. В работе исследованы модельные рецептуры на основе смесей полярного бутадиен-нитрильного (БНКС-18), неполярных бутадиенового (СКД) и изопренового (СКИ-3) каучуков. Выбор удовлетворительно морозостойкого каучука БНКС-18 обусловлен стремлением обеспечения достаточной стойкости разрабатываемых материалов в углеводородных рабочих средах. В свою очередь, смесь из неполярных диеновых каучуков СКД и СКИ-3 выбрана для дальнейшего улучшения низкотемпературных свойств и придания дополнительной стойкости в полярных рабочих жидкостях. Добавление СКИ-3 также обеспечивало подавление кристаллизации бутадиенового каучука СКД. Установлено, что с повышением содержания БНКС-18 происходит улучшение физико-механических свойств, износостойкости, стойкости к неполярным углеводородным маслам, а также снижение низкотемпературных свойств и стойкости к полярным маслам. Дополнительно были проведены исследования структуры полученных материалов методом атомно-силовой микроскопии, доказавшие равномерность распределения частиц дисперсной фазы, размеры которой не превышают 1–5 мкм. Оптимальное соотношение бутадиен-нитрильного и диеновых каучуков 70:30 (масс. ч.) соответственно. Именно при таком соотношении получены эластомерные материалы, которые отвечают требованиям для создания из них уплотнительных устройств для работы в условиях холодного климата.</p></abstract><trans-abstract xml:lang="en"><p>Elastomeric materials for sealing devices operated in the Far North, including the Republic of Sakha (Yakutia), must be resistant to working environments and have frost and wear resistance with acceptable physical and mechanical properties. Some of the listed properties are mutually exclusive and are not always achievable in materials based on individual rubber. Thus, one promising method for sealing elastomeric materials is the use of rubber mixtures. In this study, model blends based on nitrile-butadiene (BNKS-18), butadiene (SKD), and isoprene (SKI-3) rubbers were studied. Nitrile butadiene rubber was chosen as the component of the mixture responsible for resistance to working environments, and diene rubbers (SKD and SKI-3) were chosen as the components responsible for frost resistance. The addition of SKI-3 also suppressed the crystallization of SKD butadiene rubber. An increase in the BNKS-18 content enhanced the physical and mechanical properties and resistance to wear and non-polar oils. A decrease in lowtemperature properties and resistance to polar oils was also observed. Additionally, studies of the structure of the obtained materials by atomic force microscopy were carried out, which proved the uniformity of the distribution of particles of the dispersed phase, the size of which did not exceed 1-5 μm. The optimal ratio of butadiene-nitrile to diene rubbers was 70:30 phr. At this ratio, the obtained elastomeric materials meet the requirements of sealing materials for operation in cold climates.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бутадиен-нитрильный каучук</kwd><kwd>бутадиеновый каучук</kwd><kwd>изопреновый каучук</kwd><kwd>смеси каучуков</kwd><kwd>резина</kwd><kwd>морозостойкость</kwd><kwd>износостойкость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nitrile rubber</kwd><kwd>butadiene rubber</kwd><kwd>isoprene rubber</kwd><kwd>rubber mixture</kwd><kwd>elastomeric material</kwd><kwd>frost resistance</kwd><kwd>wear resistance</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования РФ (Госзадание № FSRG-2023-0026).</funding-statement><funding-statement xml:lang="en">This study was supported by the Ministry of Science and Higher Education of the Russian Federation (Grant Number №FSRG-2023-0026).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кондаков Л.А., Голубев А.И., Овандер В.Б. и др.
