Description

technical field [0001] The invention belongs to the technical field of rubber sealing materials, in particular to a low-temperature oil-resistant nitrile rubber and its preparation method and application. Background technique [0002] In the field of aerospace, when the aircraft flies at an altitude of 8,000 meters, the ambient temperature will vary between -70 and 100°C; in this environment, oil-resistant sealing materials are required to have excellent oil resistance and Very good low temperature resistance. At present, the ordinary nitrile rubber materials, fluororubber materials and fluorosilicone rubber materials used today cannot meet the requirements of the aerospace field, which brings great safety hazards to aircraft and limits national defense technology and The development of weapons and equipment. Moreover, the production cost of existing fluorosilicone rubber materials is extremely high, and large-scale industrial production has not yet been formed; there are ...
