Polypropylene (PP)/ recycled acrylonitrile butadiene rubber (NBRr)/ banana skin powder (BSP) composites were studied. Different BSP filer loading (5, 10, 15,20,25,30 wt. %) were prepared by using heated two roll mill at 180 °C. Then, the composites were tested for functional group using FTIR model Perkin Elmer Series 2. Field Emission Scanning Electron Microscope (VPFESEM) model Zeiss SUPRA 35VP also were using for morphological study. The effect of 3-aminopropyltrimethoxysilane (APS) as coupling agent were evaluated.The FTIR test shows different bands around 3200-3500 and 1740 cm-1 which represent the stretching of OH and C=O groups respectively. As for BSP which composed mostly of cellulose, hemicelluloses and lignin, the cellulose backbone C-OH is represent by the peaks of 1050 and 1048 cm-1 respectively. The γ-APS intense band around 1167 cm-1 and 1098 cm-1 in treated composite was assigned to the stretching of the-Si-O-Cellulose and –Si-O-Si-bond respectively. The large band around 1050 cm-1 found on BSP filler was attribute to the –Si-OH group which later this band will disappear after the surface modification. This evidenced that bonding between γ-APS treated BSP with PP/NBRr matrices. Morphological study supported this finding which BSP filler treated with γ-APS has improved the adhesion between BSP filler and PP/NBRr matrices.

For the industrial production of rubber, one of the key ingredients is a processing aid. It not only facilitates the processability but also tunes the final properties of the resultant rubber. In general, for a polar rubber like acrylonitrile-butadiene rubber (NBR), the processing aids earning the most attention are synthesized from petroleum, such as dioctyl phthalate (DOP). However, due to their toxicity, many rubber chemists have tried to find alternative chemicals that are environmentally friendly and derived from a renewable resource. In this research, we investigated the effects of the soybean oil fatty acid (SBOFA), synthesized in house via hydrolysis of SBO, on the properties of NBR in comparison with DOP. Initially, it was found that the addition of SBOFA improved the flowability of the NBR compound, as indicated by the progressive decrease in the Mooney viscosity with increasing levels of SBOFA. The results from various techniques indicated that the crosslink density of the NBR vulcanizates passed through the maximum at the SBOFA loading of 4 phr. Upon loading SBOFA up to 4 phr, there was no significant deterioration in the mechanical strength of the SBOFA-plasticized NBR vulcanizates. Typically, the presence of SBOFA at 4 phr enhanced the thermal resistance of the NBR vulcanizate by shifting the thermal decomposition to a higher temperature. At a given loading, it was found that the SBOFA-plasticized NBR vulcanizate showed a comparable plasticizing efficiency and mechanical strength with the DOP-plasticized one. The result from this study shows that SBOFA is a good alternative sustainable eco-friendly processing aid to use for NBR.
