STUDY OF MECHANICAL PROPERTIES OF VULCANISATE BASED ON SRI-3 RUBBER AND BIOPOLYMER
*Dr. Abdinli Orxan
This study investigates the mechanical properties of vulcanizates based on SRI-3 rubber with the addition of a natural biopolymer derived from grape leaves. The aim of the research was to develop composite materials with improved performance characteristics and enhanced environmental safety by utilizing renewable plant-based components. Various curing methods for SKI-3-based rubber compounds modified with the biopolymer were examined, including classical sulfur vulcanization. The results showed that the main vulcanization parameters — such as scorch time, tensile modulus, and total vulcanization time — remain comparable across the studied systems. The use of grape leaf as a modifier demonstrated that the resulting vulcanizates possess very high mechanical properties. The tensile strength reaches 24 MPa, which is 1.5 times higher than that of standard SKI-3-based rubber. The study also revealed that the residual elongation of the developed rubber is only 2%.
