Abstract

The efficiency of application of additives of butyl regenerate in elastomeric compositions based on a combination of chlorobutyl and natural rubber has been investigated. The effect of the type and dosage of butyl regenerate on the plastoelastic and vulcanization properties of rubber compounds, elasticstrength indicators of rubbers and their resistance to thermal aging in air has been established. Two types of butyl regenerate were introduced into compositions, obtained by the radiation method at irradiation doses of 30 kGy (BR (30)) and 50 kGy (BR (50)), as well as additionally subjected to special processing in a laboratory pin type cold feed extruder. The dosage of the regenerate was 5.0; 10.0; 15.0 and 20.0 phr. The prospect of using a secondary product in elastomeric compositions was shown, which will reduce the cost of manufactured products while maintaining the main quality characteristics. It was determined that the introduction of the regenerate into elastomeric composition in dosages of 5.0 and 10.0 phr, the Mooney viscosity of rubber compounds changes by 2.4%, and the time to reach the optimal degree of vulcanization by 1.4% compared to the composition without additive. At the same time, the use of butyl regenerate in the indicated dosages does not significantly affect the elastic-strength properties of rubbers and their resistance to thermal aging in comparison with rubber without regenerate.
