Abstract

The article is devoted to the study of the influence of thermal modes of vulcanization on the change in the main kinetic parameters of structuring and physical and mechanical parameters of lining rubber compounds and rubbers based on them. The objects of the study were elastomeric compositions based on natural rubber, intended for the manufacture of the carcass and breaker of truck tires. The analysis of the kinetic parameters of vulcanization for lining rubber compounds showed that increase in temperature accelerates the process of their structuring, which is manifested in an increase in the overall rate of vulcanization. On the other hand, the toughening of the temperature mode of vulcanization violates the regularity of the spatial structure due to the activation of side processes, which leads to a decrease in the indicators of the elastic-strength properties of rubbers and the rebound elasticity. Similar dependences of changes in the properties of covering elastomeric compositions were determined with varying the duration of vulcanization. When choosing the final thermal mode of tire vulcanization, first of all, it is necessary to take into account the results of a comprehensive assessment of the most important properties of the main constituent elements of the product.
