Physical and mechanical properties test according to the national standards [3]; oil resistance reference to "GB/T 1690-2006 vulcanized rubber, liquid-resistant experimental methods." in order to simulate the rubber work in high temperature oil, put the samples into the crude oil from Liaohe Oil field in Liaoning for soaking, then in the oven heat to 80˚C，soak time is divided into short-term (1-3 days) and long-term (1-6 weeks).
Figure 1 shows the relationship between the soak time in crude oil and the rate of change of quality of samples.
As can be seen from Table 1, fluoride, bromide, iodide and mixed solution method for surface modification to nitrile rubber, the hardness increases, the tensile strength and elongation rates have improved significantly.
