Description
Summary:The changes of mechanical properties of chloroprene rubber, used as a jacket material for electric cables in nuclear power generating stations, were investigated under various deterioration environments. The heat resistant properties of the rubber material were measured at various temperatures using a stress relaxation method. From the view point of stress-strain behavior and chemorheology, the addition of antioxidant and/or antirad reagent to the rubber improves the resistance to heat and/or radiation, respectively. The effects of dose-rate and surrounding atmosphere on the mechanical properties of rubber under radiation were also studied. The radiation damage of rubber was accelerated remarkably under a pressure of 90 atm of air.
