| contents | <p>Rubber technical products are one of the main products with the widest<br>range of uses today. In order to expand the scope of RTM use, it is necessary<br>to increase its varieties. The most demanded rubber products are rubber<br>products with high mechanical strength in contact with ozone. In this work,<br>several polymer mixtures were used to obtain ozone-resistant rubber<br>products. For this purpose, ethylene propylene terpolymer, polyvinyl<br>chloride and butadiene-nitrile rubber were used. First, a binary system was<br>created based on these polymers, their flow index was determined, and most<br>importantly, their ratios to each other were determined. In order to prepare a<br>composition based on these three polymers, an optimal recipe was selected<br>using the mathematical modeling method, and a rubber mixture was<br>prepared in laboratory cylinders based on this recipe. The mixing mode and<br>the sequence of adding components were determined, and it was confirmed<br>that the mixing process should be carried out at a temperature of 90 ° C and<br>for 12 minutes. The vulcanization mode and time were also determined, and<br>it was possible to obtain ozone-resistant rubber that could meet all operating<br>conditions with a vulcanization temperature of 155 ° C and a period of 21<br>minutes. The main properties of the vulcanization are the strength limit in<br>dispersion of 19. MPa (Standard 17.6), 71.1k/Hm (Standard 64.3) in ozone<br>dispersion. Since the results were obtained using only the most modern<br>analysis methods, it is possible to produce new rubber technical products<br>based on the results obtained in this work in the production of ozoneresistant<br>rubber products.</p> |
