Abstract
The invention discloses an ethylene-propylene-diene monomer and fluororubber compound sealing gasket material which is prepared from the following raw materials in parts by weight: 100-110 parts of ethylene propylene diene monomer (4045), 10-12 parts of fluororubber, 4-6 parts of zinc oxide, 8-10 parts of magnesium oxide, 13-14 parts of tetradecyl methacrylate polymer, 10-12 parts of para-tert-butylphenol formaldehyde resin, 3-4 parts of zinc stearate, 40-45 parts of N660 carbon black, 45-60 parts of spraying carbon black, 0.5-1.5 parts of accelerant CBS (N-Cyclohexy-2-Benzothiazole Sulfonamide), 1-2 parts of accelerant M, 2-3 parts of accelerant DM (dibenzothiazole disulfide) and 10-12 parts of modified attapulgite. According to the ethylene-propylene-diene monomer and fluororubber compound sealing gasket material, by adding the modified attapulgite, the process property of a rubber material is improved; by using an environment-friendly compounding agent, the toxic and side effects and the pollution to the environment are reduced. The ethylene-propylene-diene monomer and fluororubber compound sealing gasket material is reasonable in formula, simple in process and low in cost and has better oil resistance and sealing property.
