| Abstract: |
| The antistatic carboxyl nitrile latex gloves were prepared by combining carbon conductive
materials[single wall carbon nanotube （SWCNT） and superconducting carbon black] with the carboxyl
nitrile latex，and the effect of the carbon conductive material amounts on the properties of the film of the
antistatic carboxyl nitrile latex gloves was studied. The results showed that，with the increase of the SWCNT
amount，the surface resistance and volume resistance of the film of the antistatic carboxyl nitrile latex glove
decreased，the tensile strength first increased and then decreased，the penetration time of concentrated sulfuric
acid resistance was about 32 ～ 35 min. When the SWCNT amount was 0. 1 phr，the volume resistance and
surface resistance of the film of the antistatic carboxyl nitrile latex glove decreased to 60 MΩ·cm and 94
MΩ respectively，the tensile strength was the largest（26. 9 MPa）. With the increase of the superconducting
carbon black amount，the volume resistance and surface resistance of the film of the antistatic carboxyl
nitrile latex glove decreased，the tensile strength decreased too，the elongation at break increased，and the
penetration time of concentrated sulfuric acid resistance shortened. When the superconducting carbon black
amount was 4 phr，the volume resistance and surface resistance of the film of the antistatic carboxyl nitrile
latex glove decreased to 54 MΩ·cm and 89 MΩ respectively，and the penetration time of concentrated
sulfuric acid resistance was shortened to 15 min when the superconducting carbon black amount was 10 phr.
The performance of the antistatic carboxyl nitrile latex glove decreased with the extension of time. |
