Abstract

The technical properties of tire rubber containing a combination of carbon black and silica filler have been determined. The objects of study were elastomeric compositions based on natural rubber, containing high-reinforcement carbon black type N347 and silica filler type Perkasil-408. In the recipes, a partial replacement of 10.0 and 20.0 phr including carbon black for mineral filler with the rest of the composition of the rubber mixture unchanged. It has been established that the introduction of silica filler leads to the production of elastomeric compositions with increased resistance to heat aging. At the same time, vulcanizates with 10.0 phr by weight of silica are less susceptible to elevated temperatures and atmospheric oxygen compared to other rubbers (the change in the tensile strength of rubbers with the specified dosage of silica is (–13%); elongation at break (–12%), and for other rubbers studied, the change in tensile strength is (–17%) and (–15%), and the change in elongation at break is (–22%) and (–19%). Partial replacement of high-strengthening carbon black with the mineral filler Perkasil-408 increases the fatigue endurance of rubber under repeated stretching by 8.6–23.9%, and the resistance to crack propagation by 2.08–2.26 times. The identified features of the technical properties of rubber are due to their peculiarities of the spatial structure.
