Preparation and Study of a Composition Based on Butadiene-Styrene Polymer using Wood Tar

Abstract

This work is devoted to the topic of preparation and study of a composition based on butadiene-styrene polymer using wood tar.
An optimal recipe for obtaining a rubber mixture using butadiene-styrene rubber and wood tar (which we will sometimes call Kamden in the future) was selected and each component was justified. The rubber mixture was prepared in a mixer located in the laboratory of Bakrezin JSC and the mixing mode was set at a temperature of 1200C for 14 minutes, and the obtained homogeneous dispersed system was cooled to 800C, sulphur and accelerators were added to it. Then the kinetics of the vulcanization process was found. The vulcanization mode was determined as follows: T-1580C, P -12MPa, t - 26 minutes.
The physical and mechanical properties of the vulcanization were studied and it was shown that the indicators of the obtained product meet the requirements of the standard. To determine the durability of these rubber products obtained, the physical and mechanical properties of the vulcanization were determined and the sample had the following characteristics: Tensile strength, 22 MPa, Elongation at break 340%, Residual elongation 12%. Hardness according to TM-2, 85 conventional units.
