Exploring the effect of electron beam on swelling,gel fraction,mechanical and thermal properties of ethylene acrylic elastomer/millable polyurethane rubber blends
Ethylene acrylic elastomers (AEM) and millable polyurethane (MPU) blend have been prepared successfully using dicumyl peroxide (DCP) system and the blend ratio is optimised on the basis of the tensile results. The optimised unvulcanised blend ratio (60:40) is subjected to different electron beam (EB) dose to obtain uniform three dimensional crosslinking networks. The characteristic shifting of = CO vibration in the Fourier-Transform Infrared spectra confirms the formation of hydrogen bonding between the two phases. The phase morphology of the two phases in the optimised blend has been captured in SEM and the results show the successful integration of MPU in AEM phase. It is found that the swelling of the irradiated blend decreases with increase in EB dose, whereas the increase in gel fraction and the crosslink density is due to the irradiation-induced crosslinking. The thermal stability of the irradiated blend has been improved in compression to the pristine form of individual phase.
