Development of High Temperature Nuclear Radiation Resistant Flame Retardant Rubber Hose
High-temperature nuclear radiation-resistant flame-retardant vulcanized rubber was pre-pared by using EPDM and selecting lead monoxide/bismuth oxide as nuclear radiation-resistant sys-tem,DCP/DM/TMTD as vulcanization accelerator system,high-wear-resistant carbon black N330/fumed silica/graphene as reinforcing system,4010NA/RD as protection system,chlorinated paraffin/antimony trioxide as flame retardant system and phenolic resin as plasticizing system.Through extrusion and steel wire braiding and other molding processes,the high-temperature nuclear radiation-resistant flame retardant rubber hose was successfully produced.The results showed that this type of rubber hose had excellent high temperature resistance,nuclear radiation resistance,aging resistance and flame retardant characteristics,which could effectively shield the effects of high temperature nuclear radiation,and was suitable for use in nuclear radiation environment.Long-term use could main-tain excellent comprehensive mechanical properties,with stable performance,safety and reliability and high durability.
