Abstract:
      The influence of curing system，curing time and reinforcement system on the properties of chloroprene rubber 2442（CR2442） for deep sea watertight connectors were investigated. The results showed that，the tensile strength of the compound was the best as the curing time was 60 min. The hardness of CR2442 compound could increase by 0.4-0.5 as the addition level of carbon black N550 or silica increased by 1 phr. The optimal formulation was as follows：CR2442　100，carbon black N550　20，silica　10，ZnO　4，MgO　2，aromatic oil　14，active agent SAD　0.5，antioxidant RD　1，antioxidant 4010　2，sulfur　2，and accelerator DM　0.15. The properties of the compound met the requirements of deep-sea watertight connector.
