One of the most common materials witch used in everyday life and industry is a rubber compositions, whose history of creation has more than 200 years. Rubber compositions are multicomponent systems based on rubbers, which include inclusions for various purposes: stabilizers, activators, antioxidants, etc., and fillers such as white carbon black, carbon black and others. Recently, hybrid fillers of various sizes have been used, namely, compositions of carbon black and carbon nanotubes (CNTs) [1]. As a rule, the improvement of perfect formulations developed over many years is carried out by trial and error, so it is obvious that it is interesting to consider the possibility of predicting the composition of the hybrid fillers of carbon black and CNTs.
The work proposes a method of modifying a rubber composition filled with carbon black by introducing carbon nanotubes, which includes the preliminary formation of a mixture of carbon black with CNT treatment in a liquid, which provides deagglomeration of carbon nanotubes and uniform distribution of tubes and soot, further drying and introducing rubber into the composition by stirring. The quantity and composition of the hybrid nanofiller (carbon black + CNT), as well as the introduction of CNT: in addition to carbon black, the replacement of carbon black or its partial replacement, is determined by a calculation that takes into account the ratio between the specific surface area of carbon black and CNT and their average sizes.
