The invention discloses a nitrile rubber sheath, which adopts the technical scheme that: the nitrile rubber sheath comprises a main material and an auxiliary material, wherein the main material comprises nitrile rubber and modified autumn hemp fiber (by weight), the auxiliary material comprises ammonium polyphosphate, trimethylol methylamine, dicumyl peroxide, microcrystalline wax, white carbon black, a coupling agent, an anti-fatigue agent, an accelerator, zinc oxide, barium erysipelate, triallyl isocyanurate, trioctyl trimellitate, a softener and a wear-resistant agent (by weight), and the nitrile rubber sheath has the beneficial effects that: zinc oxide is added into natural rubber in a proper proportion, so that the prepared sheath has good wear resistance, tearing resistance and elasticity, and the increase of the crosslinking density of the rubber is promoted; the softener with a proper proportion is added, so that the folding resistance of the sheath is greatly improved; the ammonium polyphosphate with a proper proportion is added, so that the fireproof and fire-retardant performance of the sheath is enhanced; the nitrile butadiene rubber retains the excellent oil resistance, higher wear resistance, better heat resistance and strong bonding force of the nitrile butadiene rubber. |
