Background: Rubber/Nano aluminum oxide nanocomposites may be considered as potential materials in mechanical applications because of the adaptability of the polymer properties of the nanometric substance. Rubber nanocomposite was prepared by using emulsion polymerization method. Mechanical properties and environmental resistance properties are evaluated for better rubber-filler interaction.

Purpose: In this examination, the Raman spectroscopy and mechanical properties of nanocomposites based on Styrene-Butadiene rubber have been explored within the sight of nano aluminum oxide additive. The nanocomposites have been prepared by mechanical mixing utilizing two-roll mills. Nano aluminum oxide particles suspensions have been added to Styrene-Butadiene rubber and the abrasion and spectral properties have been overviewed.

Materials and Methods: Nano aluminum oxide, 2, 2’- dithiobis, tetramethyl thiuram disulfide, N, N’- Diphenyl P- phenylene diamine and Styrene-butadiene rubber latex were used for analysis. SBR- Nanocomposite was obtained by using emulsion polymerization method.

Results: Mechanical test outcomes demonstrated that improvement in tensile strength, elongation and tear resistance. Abrasion test results demonstrated that the nano aluminum oxide particles could improve the abrasion resistance of Styrene Butadiene rubber matrix because of correct properties of nano aluminum oxide particles. The strengthening capacity of the fillers results in noteworthy upgrades in 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, inside a low loading amount. The collection idea of the combined rubber nano composite was built up by scanning electron microscopy (SEM). The impact of nano particles in polymer network have been assessed for the SBR-nano aluminum oxide from TEM investigation. Thermogravimetric analysis (TGA, DTA) also examined. Ozone resistance was studied to elucidate periodic observations of the surface of the samples were made for crack initiation. Samples were exposed for longer time. Flame resistance was studied to measures the ease of extinction of a flame and four ratings are possible, depending upon the burning time and the presence of flaming drips.

Conclusion: The present study involving the emulsion polymerization method where environmental resistance performance of rubber-nanocomposites is found to be good and thermal properties and mechanical properties are also enhanced.
