Embodiment Construction
[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0041] As an embodiment of the present invention, nitrile rubber 5176S is selected to carry out deformation rate accelerated aging test.
[0042]1. Conduct accelerated aging tests on nitrile rubber 5176S at different installation compression ratios and different temperatures. In this example, the deformation rate h(t) / h of nitrile rubber 5176S at the installation compression rate of 24%, 19% and 14% and the temperature of 75°C, 85°C and 95°C were respectively tested 0 , the data are shown in Table 1, Table 2 and Table 3.
