Description

technical field [0001] The invention relates to the field of rubber materials, in particular to an oil-resistant and heat-resistant rubber material and a preparation method thereof. Background technique [0002] Nitrile rubber has high stability to non-polar or weak polar mineral oils, animal and vegetable oils, liquid fuels and solvents, so nitrile rubber is often used to make oil-resistant hoses, oil-resistant sealing rings, oil-resistant conveyor belts, etc. rubber products. And with the development of petroleum and automobile industries, more stringent requirements are put forward for nitrile rubber, which promotes the research of nitrile rubber. Silicone rubber is widely used in the fields of electrical, electronic, office equipment, automobile, construction, medical, food and artificial organs due to its excellent weather resistance, high and low temperature resistance, electrical insulation, radiation resistance, and biological inertness. Silicone rubber can be used...
