The invention discloses a modified nitrile-butadiene rubber fuel pipe, which is made of the following raw materials in parts by weight: 70-75 parts of nitrile-butadiene rubber/polyvinyl chloride blend rubber, 20-25 parts of THV, 0.3-25 parts of THV 0.5 part of modified graphene oxide, 0.3-0.5 part of modified nano-Al 2 O 3 , 3-5 parts of zinc oxide, 55-60 parts of modified nano-silica, 10-12 parts of modified mica powder, 2-3 parts parts of stearic acid, 1-2 parts of antioxidant MB, 2-3 parts of paraffin, 8-10 parts of aromatic oil, 1-2 parts of accelerator M, 2-3 parts of sulfur. The invention optimizes the formula of the fuel pipe, and the prepared modified nitrile-butadiene rubber fuel pipe has excellent fuel resistance, ozone resistance and heat resistance, and is not easy to accumulate static electricity. The invention also discloses a method for preparing a modified nitrile-butadiene rubber fuel pipe. By limiting the feeding sequence, the mixing quality is ensured, the process steps are simple, the operability is strong, and it is suitable for industrial production. |
