1, oil-resistant rubber vulcanization system
In general, improving crosslink density can improve the oil resistance of vulcanized rubber.
In the oxidation of fuel oil, peroxide or semi-effective vulcanization system vulcanization of nitrile rubber, than sulfur vulcanization of oil resistance is good. Peroxide vulcanization system vulcanization of butyl rubber, the best stability at 40 degrees, in 125 degrees of oxidized fuel oil is not ideal. Cadmium oxide and sulfur body system vulcanization of nitrile rubber, in the 125 degrees of oxidation of fuel oil in the long-term heat aging resistance is better.
2, oil-resistant rubber filling system and plasticizer
Increase the carbon black and white carbon can improve oil resistance softener should be selected not easy to be drawn out of the oil softener. The best choice of low molecular polymers, such as low molecular polyethylene, polyethylene oxide, polyester plasticizers! and liquid rubber. Polarity, large molecular softeners or plasticizers, oil resistance is favorable.
3. Antioxidant for oil-resistant rubber
It is mainly filled with antioxidant which is not easy to be extracted.
