Electrostatic eliminating superconducting general negative ion material and preparation method and application thereof

The invention discloses an electrostatic eliminating superconducting general negative ion material and a preparation method and application thereof and belongs to the field of functional materials. The electrostatic eliminating superconducting general negative ion material is prepared from 50-75% by weight of nanometer tourmaline powder, 5-15% by weight of nano-titanium dioxide, 15-20% by weight of pseudoboehmite, 4-10% by weight of nano-silica and 1-5% by weight of graphene. The electrostatic eliminating superconducting general negative ion material is added into polyurethane sponge. A detection result shows that the produced automobile seat cushion has a negative ion release amount of 1580/cm , a radioactive internal illumination index of 0.01 and an external illumination index of 0.02. The negative ion material has a far-infrared detection wavelength range of 4-16 micrometers, is greater than 70% (national standard greater than 50%), normal thermal emittance of 0.88 (national standard greater than 0.8), a
