Abstract
The invention discloses a special nitrile rubber sealing ring for a capacitor. The special nitrile rubber sealing ring is characterized in that the special nitrile rubber sealing ring is made by using the following raw materials, by weight, 78-85 parts of nitrile rubber 3345, 2-3 parts of a coupling agent KH-550, 2-5 parts of tetraphenyl resorcinol diphosphate, 1-2 parts of ammonium polyphosphate, 20-25 parts of precipitated silica, 1-2 parts of sulfur, 2-4 parts of magnesium oxide, 3-5 parts of molybdenum disulfide, 2-4 parts of barium stearate, 1-3 parts of methyltrimethoxysilane, 1-2 parts of an accelerant Na-22, 5-8 parts of butyl stearate and 12-15 parts of modified attapulgite. The addition of the modified attapulgite improves the technological performances of a rubber compound, and the use of the an environmentally-friendly compounding agent reduces the toxic side effects of the rubber compound and the pollution to the environment; and the special nitrile rubber sealing ring has the advantages of high tensile strength at break, cost saving, superior performances and very good oil resistance.
