Abstract
Study of binary systems based on butadiene-terephthalate rubber and Astragals and it In this work, Nano sized astragals was used for the first time to modify butadiene terephthalate rubber. For this purpose, compositions were prepared to study the properties of butadiene terephthalate rubber with different astragals contents of 1, 3 and 5 mass parts. Their results were compared with the control composition without nanoparticles. The presence of astragals and its distribution in the matrix of butadiene terephthalate rubber was confirmed by determining the melt flow indices of the binary system and IR analysis. The effect of Nano sized astragals modification on the main rheological properties of polybutylene terephthalate was studied. The effect of Nano sized astragals on the kinetics of vulcanization was studied To select the vulcanization mode of the rubber compound, the optimum and plateau of the vulcanization process were determined, and it was established that the onset of vulcanization begins at 127 °C and ends at 155–157 °C. The vulcanization process was carried out at a temperature of 1750C and The main indicators of the obtained vulcanizate were determined by the physical and mechanical properties of the vulcanizates by known methods. The obtained data were compared with reference rubbers. In terms of strength, the proposed rubber exceeds the standard by 1.2 times. The ultimate strength of the vulcanizate sample is achieved up to 26 MPa.
