Abstract

The main purpose of this work was to establish the influence of carbon-silicon composite (CSC) as a new biocomponent of industrial formulations of elastomeric compositions on the main technological and operational characteristics of vulcanizates. The objects of the study were elastomeric compositions based on polar butadiene-nitrile rubber (BNKS-18) and a combination of synthetic nonpolar rubbers SKI-3 + SKD containing CSC in various dosages. A study of the viscosity according to the Muni of rubber mixtures based on BNKS-18 showed that the CSC reduces this indicator to 9.6%, in the case of SKI-3 + SKD, the viscosity according to the Muni will increase to 5.8%. The determination of the kinetic parameters of the vulcanization process of rubber mixtures revealed that when the CSC is introduced into rubber mixtures based on BNKS-18, the time to achieve the optimum vulcanization increases, at the same time, the resistance of rubber mixtures to premature vulcanization increases. The results of determining the rheological parameters of rubber mixtures based on SKI-3 + SKD containing CSC revealed an insignificant change in the time to achieve the optimum vulcanization. Determination of the main operational characteristics of the studied elastomeric compounds showed that the use of CSC in dosages up to 10 wt. h. allows to obtain vulcanizates with a given set of technical characteristics of products.
