Abstract
Currently, recycling waste from various types of production, as well as finding the possibility of reusing it, is a very relevant topic. In the modern world, rubbers make a tremendous contribution to the development of the industrial sector. In order to study the possibility of using pyrite cinders as a filler for a rubber mixture based on styrene-butadiene rubber, the elastic-strength and rheological characteristics of the finished composite mixtures were studied, and the contact angle of wetting was determined to assess the interaction of the compositions with other materials. It was established that there was no influence of pyrite cinders on the nature of the surface of the rubber mixture. The dependence of the storage modulus on the deformation amplitude for different types of fillers has been established, which makes it possible to evaluate the qualitative and quantitative distribution of the filler in the polymer and the interaction of the polymer and the filler. It was revealed that pyrite cinders and chalk have a weak interaction with the polymer, from which it follows that they behave as a non-reinforcing filler, but their introduction into the polymer matrix does not deteriorate the elastic-strength properties of the rubber. The dependence of stress on deformation for mixtures with different types of fillers has been established. It was established that in terms of technological characteristics, no deviations in the material from the generally accepted patterns of introducing fillers into the polymer matrix were found. The values remain at the level of unfilled rubber and rubber filled with technical chalk. The general complex of properties of the composition based on styrene-butadiene rubber with pyrite cinders allows it to be recommended, after modification, for use in the production technology of rubber products.
