Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a high-temperature-resistant, wear-resistant and aging-resistant rubber material and a preparation method thereof. Background technique [0002] At present, rubber products are used in all aspects of social life, such as various rubber production equipment or rubber parts in heavy industries such as mining, transportation, construction, machinery, electronics, and emerging industries. However, when ordinary rubber materials encounter working environments with acid-base or salt solutions, they are often corroded due to frequent contact with chemicals such as acid-base or salt, resulting in rubber swelling, rubber molecule breakage, and depolymerization, which in turn increases its mechanical strength. And physical properties are significantly reduced, or even completely lose their due effect, which will directly affect production safety and personal safety, and cannot mee...
