Abstract

The article studies the effect of temperature-time parameters on the elastic and strength and structural characteristics of tire rubbers before and after heat aging in order to establish the most acceptable technological mode of vulcanization. The object of the study was an elastomeric composition based on natural rubber with a semi-effective vulcanizing system, intended for the manufacture of a tread for automobile tires. The analysis of the vulcanization parameters of the studied mixtures showed that the vulcanization temperature has a significant effect on the physicochemical process of their structuring, which is expressed in the change in the plastoelastic and technical parameters of rubber compounds and vulcanizates based on them. It was found that with an increase in the temperature and duration of vulcanization, destruction processes become predominant, leading to the formation of a less dense structure, a decrease in its heterogeneity and the active portion of the network, which has a negative effect on the mechanical pro­-perties of tread rubbers. Varying the vulcanization parameters makes it possible to regulate the structure of the vulcanizates and thereby change the basic elastic and strength properties and their resistance to heat aging.
