Abstract: SKN-40 rubber is compatible with other ingredients, mixes quickly and improves the physical and mechanical properties of vulcanizate. For this purpose, based on standard indicators, it is necessary to prepare a rubber mixture based on comparative dioctylphthalate, dibutylphthalate and their combination and to study its physical and mechanical properties by vulcanizing it. In the laboratory, it is possible to synthesize diphenylolpropane dicaprylate and diphenylolpropane oxypropylene esters on the basis of naphthenic acids and use it as a plasticizer in SKN-40 rubber. Using this new plasticizer synthesized is to obtain rubber resistant to aggressive environments. The following issues have been resolved to achieve the set goal: - preparation of polymer compositions using new types of plasticizers; - research of technological parameters of polymer-plasticizer system, study of interfacial field, structure and properties of polymer composition; - study of rheological properties of the polymer composition prepared depending on the type of polymer base and plasticizer; - Vodka of the components of the mixture, cuff, sealant, vulcanization, rheological properties. study of physical and mechanical properties of the polymer composition depending on the ratio; - Research of technological mode of processing of plasticized polymer composition with sulfur vulcanization; -development of proposals on perspective directions of application of the studied polymer composition; For the first time in the polymer composition based on SKN-40 rubber, diphenylpropane dicaprylate and diphenylolpropane oxypropylene esters were used as plasticizers. These organic compounds, which are esters of naphthenic acids, are characterized by high technological parameters. The plasticizers we use are very important for composition systems. The functional groups in the esters affect the rubber macromolecule, forming new vulcanization networks. The results confirmed the use of this plasticizer to produce rubber that meets the requirements and can work in aggressive environments.
Key words: Butadiene-nitrile rubber, plasticizer, composition, technological parameters, aggressive environment, technical carbon, vulcanization, physical and mechanical properties.
