摘　　要：采用碳系导电材料[单壁碳纳米管(SWCNT)和超导电炭黑]与羧基丁腈胶乳配合以制备防静电羧基丁腈胶乳手套,并研究碳系导电材料用量对防静电羧基丁腈胶乳手套胶膜性能的影响。结果表明:随着SWCNT用量的增大,防静电羧基丁腈胶乳手套胶膜的体积电阻和表面电阻呈减小趋势,拉伸强度先增大后减小,耐浓硫酸穿透时间为32~35 min;当SWCNT用量为0.1份时防静电羧基丁腈胶乳手套胶膜的体积电阻和表面电阻分别减小至60 MΩ·cm和94 MΩ,拉伸强度最大(26.9 MPa);随着超导电炭黑用量的增大,防静电羧基丁腈胶乳手套的体积电阻和表面电阻呈减小趋势,拉伸强度减小,拉断伸长率增大,耐浓硫酸穿透时间缩短;当超导电炭黑用量为4份时防静电羧基丁腈胶乳手套胶膜的体积电阻和表面电阻分别减小至54 MΩ·cm和89 MΩ,当超导电炭黑用量为10份时胶膜的耐浓硫酸穿透时间缩短至15 min;防静电羧基丁腈胶乳手套的性能随时间的延长而降低。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 MΩrespectively,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 MΩrespectively,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.
