Study of the Influence of Grape Leaves on the Properties and Structure of SREPT-60 Rubber Modification

This study investigates the modification process of SREPT-60 with grape leaves.. It is shown that modification requires obtaining grape leaf nanoparticles and then performing the modification. The study found that the optimal amount of grape leaf particles for modification is 8-10% by weight. The wear resistance and electrical resistance of rubber obtained from SREPT-60 rubber compounds and grape leaves were studied. The results show that increasing the grape leaf mass to 8 parts by weight improves the overall rubber performance. At a frequency of 50 Hz, the permittivity decreases from 2.3 to 2.9, and the dielectric loss tangent tanδ decreases from 10⁻² to 10⁻³, while the breakdown strength increases. In this study, grape leaves were used for the first time to modify rubber. The modification process of a composite based on Skep-60 and grape leaves was studied in detail using modern research methods. The melt flow rate of the composite was also studied to determine the processing parameters of the resulting composite.
