Özet

Vulcanization at lower temperatures can be considered as a good alternative to reduce both investment and operation costs for cable insulation sheat and special purpose hose production lines. In this study, silane vulcanization of chlorinated polyethylene and chloroprene rubber blends at lower temperature was investigated. Rubber compounds were prepared by using internal mixer instead of an extrusion system which is widespread used for projected applications. Rheological and dynamic properties of the rubber compounds were studied. After vulcanization, physico-mechanical, thermal, morphological and temperature scanning stress-relaxation properties were investigated before and after thermal aging. Structural analysis was performed by using Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy so as to identify vulcanization reaction mechanism. All the compound compositions could be vulcanized at 110 degrees C in the presence of water. Amino silane was found to be more effective than epoxy silane.
