The invention belongs to the technical field of materials, and particularly relates to an NBR/PP thermoplastic elastomer and a preparation method thereof. Wherein the NBR/PP thermoplastic elastomer comprises the following raw material components in parts by mass: 20-50 parts of nitrile rubber, 10-40 parts of polypropylene, 5-30 parts of a plasticizer, 5-25 parts of a compatilizer, 2-8 parts of a vulcanizing agent, 0.2-1 part of a vulcanization accelerator, 1-3 parts of an anti-aging agent, 3-8 parts of an activating agent, 0.2-2 parts of a heat-resistant agent, 0.2-2 parts of an antioxidant and 0-30 parts of filler. Through the synergistic effect of the raw material components, the heat resistance, oil resistance, aging resistance and other properties of the NBR/PP thermoplastic elastomer material are effectively improved, meanwhile, the NBR/PP thermoplastic elastomer material has high strength, and the tensile strength retention rate of the thermally aged material reaches 87%. The prepared ...
