Graphical Abstract:


Background: Rubber or nano aluminum oxide composites may be considered as potential materials in mechanical applications because of the adaptability of polymer properties of nanometric substances. Rubber nano-composite is prepared by using the emulsion polymerization method. Mechanical properties and environmental resistance properties are evaluated for a better rubber-filler interaction.

Purpose: In this examination, the Raman spectroscopy and the mechanical properties of nanocomposites are based on Styrene-Butadiene rubber (SBR) and were explored within the sight of nano aluminum oxide additive. The nano-composites were prepared by mechanically mixing and utilizing two-roll mills. Nano aluminum oxide particle suspensions were added to SBR and the abrasion and spectral properties were overviewed.

Materials and Methods: Nano aluminum oxide, 2, 2’- dithiobis, tetramethyl thiuram disulfide, N, N’- Diphenyl P- phenylenediamine and SBR latex were used for analysis. SBR nano-composite was obtained by using the emulsion polymerization method.

Results: Mechanical test outcomes demonstrated the improvement in tensile strength, elongation, and tear resistance. Abrasion test results demonstrated that nano aluminum oxide particles could improve the abrasion resistance of SBR matrix because of the good properties of nano aluminum oxide particles. The strengthening capacity of the fillers resulted in noteworthy upgrades in the properties of polymer framework at extremely low filler loadings when contrasted with conventional fillers. In this work, we concentrate on Raman spectroscopy and mechanical properties by including filler content within a low loading amount. The collection idea of the combined rubber nano-composite was built up by using scanning electron microscopy (SEM). The impact of nanoparticles in the polymer network has been assessed for the SBR-nano aluminum oxide from the TEM investigation. Thermogravimetric analysis (TGA and DTA) was also examined. Ozone resistance was studied to elucidate periodic observations of the surface of samples, which were made for crack initiation. The samples were exposed for a longer time. Flame resistance was studied to measure the ease of extinction of a flame and four ratings were possible, depending upon the burning time and the presence of flaming drips.

Conclusion: The present study highlights the emulsion polymerization method, where the environmental resistance performance of rubber nano-composites is found to be improved and the thermal and mechanical properties are also enhanced.

Keywords: Mechanical properties, nano aluminum oxide, raman spectroscopy, spectral properties, SBR latex, SBR nano-compound.
