Abstract:
      In order to study the compatibility of rubber and new gas fire extinguishing agents，the immersion tests of three kinds of common rubber materials，nitrile rubber（NBR），high temperature vulcanized silicone rubber（HTV） and fluorine rubber（FKM），in three kinds of new fire extinguishing agents with high boiling point，Novec 1230，HCFO-1233zd and HFO-1336，were carried out under two kinds of conditions，normal temperature-normal pressure condition and high pressure condition with temperature cycles. The change of mass and volume，the hardness and tensile properties of the rubber after immersion were tested and analyzed. The results showed that under normal temperature-normal pressure condition，three kinds of rubber were swollen easily，but they could not be dissolved easily. They were all suitable for the seals of Novec 1230 storage equipment under normal temperature-normal pressure condition，and NBR and HTV could also be used for the seals of HFO-1336 storage equipment if the volume change of the seals was not a prerequisite for the application. Under high pressure with temperature cycling condition，the dissolution rate of three kinds of rubber increased，three kinds of rubber were not suitable for the seals of HCFO-1233zd storage equipment，HTV could be used for the seals of HFO-1336 storage equipment，and NBR and HTV were suitable for the seals of Novec 1230 storage equipment.
