Examples
preparation example 1
[0046] Take 2kg of tert-butyl hydroperoxide, 0.018kg of molybdenum trioxide and 5kg of nitrile rubber, first mix tert-butyl hydroperoxide and molybdenum trioxide to obtain an intermediate solution, react at 70°C for 2 hours, and add to the intermediate solution The nitrile rubber was reacted at 60-70° C. for 40 minutes to obtain a reactant, washed with ethanol, ventilated and dried, and dried at 40° C. to obtain the epoxidized nitrile-butadiene rubber.
[0047] WSR preparation example
preparation example 2-4
[0049] Weigh the nitrile rubber, sodium polyacrylate, epoxidized nitrile rubber, sulfur, and accelerator respectively. The specific quality is shown in Table 1. Mix the nitrile rubber and epoxidized nitrile, and masticate for 5 minutes. Add sodium polyacrylate, Accelerator and sulfur are mixed, thinly passed for 5 times, sheet out, unpacked, vulcanized at 160°C, and granulated to obtain WSR1-3.
