- Abstract
The reuse of rubber has been extensively explored with mixtures with virgin polymers to generate compounds used in various applications. The aim of this work was to produce polymer blends from an array of polyamide 6 with recycled rubber waste (SBR-R). Rheology testing, heat deflection temperature (HDT), dynamic mechanical thermal analysis (DMTA), and Fourier transform infrared spectroscopy (FTIR) were performed. The blends of polyamide 6/recycled rubber waste were prepared in a twin-screw corrotational extruder and the extruded granules were molded by injection. The results obtained with rheological study showed that the greater the percentage of SBR-R added, the higher the torque values. The heat deflection temperatures of the blends decreased slightly when compared to polyamide 6. In the DMTA test, binary and ternary blends showed a shift of the peaks of approximately -10°C and the displacement of the α relaxation of PA6 toward larger values. The results of the FTIR showed that the characteristic peaks of PA6 were not modified by the presence of SBR-R nor by increasing the percentage in the binary blend and the presence of PE-g-MA in ternary blends, where their chemical groups were not affected.
