Апстракт:
In the case of irradiation of polymeric materials the progress in oxidative degradation depends on absorbed dose, dose rate, exposure environment, energy of irradiation, chemistry of material, and previous state of ageing. Chlorosulfonated polyethylene (CSM) as network precursor is specifically recommended for sheeting of cables in nuclear energetic plants. Elastomers based on CSM are resistant to wear and repeated deformation and have excellent irradiation resistance. The goal of this work was to study gamma irradiation ageing of elastomers based on CSM in combination with different rubbers. The reinforcing filler was nano-silica. The irradiation was performed in the Co60 radiation sterilization unit. The level of ageing was evaluated using the hardness, stress-strain, and swelling measurement. The use of silica nano-particles improved the swelling resistance in toluene after irradiation ageing.
