Acid-resisting,anti-aging rubber material composition and its preparation method

  Patent no:ZL 200910229839.1
  Patent introduction: This invention discloses a kind of acid-resisting,anti-aging rubber material composition and its preparation method.The material combination mentioned including the following raw materials with percent by weight:100 copies of chlorinated polyethylene,10 ~ 15copies of lead oxide, 2 ~ 5 copies of stabilizer,2.5 ~ 5copies of vulcanizing agent,1.5 ~ 3 copies of co-curing agent,1 ~ 3copies of paraffin wax, 10 ~ 40 copies of talcum powder,20~80 copies of barium sulfate, 10 ~ 50 copies of black carbon,10 ~ 25 copies of chlorinated paraffin 52 #.Put the raw materials into the  banbury mixer in order, set the temperature between 110 to 130 ℃, rubber refining for 5 ~ 10 minutes.Then refining mixing 3 ~ 5 minutes again on the open mill.Rejoin the middle materials into the mixer after mixing,join the vulcanizing agent,mixing under 100 ~ 120 ℃ for 1 minute.After that,mixing for 3 ~ 5 minutes on the open mill,press into finished products.Combination of this invention has good anti-aging and acid resistance qualities,is suitable for rubber cushion,sealing ring etc manufacturing under acidic conditions in chemical industry.
