The invention provides a high sealing material for a sensor and a preparation method thereof, and relates to the technical field of sealing material processing. The high sealing material for the sensor is made of the following raw materials by weight: 28-30 parts of natural rubber, 22-24 parts of nitrile rubber, 14-16 parts of silicone resin, 4-5 parts of nano calcium carbonate, 2 parts of boron carbide -4 parts, 3-5 parts of nano silicon carbide, 2-3 parts of sulfur, 1.2-1.4 parts of antioxidant DNP, 0.8-1 part of antioxidant MB, 2-3 parts of carboxyethyl chitosan, carbon nanotubes 1-2 parts, 2-3 parts of tetraallyl ammonium bromide, 2-4 parts of zinc methacrylate, 4-5 parts of acetylene carbon black, 1-2 parts of crosslinking agent, 1-2 parts of antioxidant, dispersion dose 0.8-1.2 servings. The invention overcomes the deficiencies of the prior art, and while ensuring the product has good elasticity, it improves its oil resistance, anti-aging and anti-deformation capabilities, enhances its sealing performance, improves the use effect, and is suitable for production and use. |
