Description
技术领域
本发明涉及一种简单制备高附着力碳纳米管导电手套的制备工艺。
背景技术
导电手套适用在弱电流、精密仪器组装、产品检查等运用指尖的作业场所及电子产品、各种研究机关的检验工程等。主要用在需用防静电手套操作的防静电环境,如电子、仪表等行业,能防止由于静电所造成的电子元器件损毁、老化;在石化行业能防止由于静电所引起的燃烧、爆炸等危险。碳纳米管导电手套比传统的防静电手套具有更好的防静电性能,避免人体产生的静电对产品造成破坏。为了给生产应用带来便利,发明碳纳米管导电手套。
发明内容
本发明的目的在于提供一种高附着力、制备方法简单的碳纳米管导电手套及其制备工艺。
本发明的技术方案如下:以碳纳米管为导电物质,以十二烷基苯磺酸钠为分散剂配制碳纳米管溶液,加入曲拉通和水性聚氨酯得到导电涂料。采用喷枪喷涂的方法在普通手套上制备导电涂层,水洗烘干后得到碳纳米管导电手套。
本发明的主要创新点如下:采用表面喷涂的方法制备碳纳米管导电手套,节约原料而且不改变手套原有工艺条件,以水性聚氨酯为粘结剂提高了导电涂层的附着力和使用寿命,可在常温常压下制备,且涂料为水性溶剂的,绿色环保无毒无害。
本发明方法中制备碳纳米管分散液方法如下:以纯度为50~96%的碳纳米管为原料,用十二烷基苯磺酸钠为分散剂配制碳纳米浓度为0.1~1wt%的水分散液,其中十二烷基苯磺酸钠浓度是1~10 wt%,超声功率为60~150 W,超声时间为30~90min。
本发明方法中碳纳米管涂料的制备过程如下:向碳纳米管分散液中缓慢加入曲拉通和水性聚氨酯,边加入边搅拌,使其浓度分别达到1~8wt%和0.1~1wt%,得到碳纳米管导电涂料。
本发明方法中碳纳米管导电手套的制备过程如下:采用喷枪喷涂的方法将碳纳米管导电涂料喷涂在加热温度为60~130℃的手套基底上,然后将手套在水中浸泡润洗2~4遍,每次10~60 min,烘干后得到碳纳米管导电手套,每次烘干温度为60~100℃。
本发明在制备碳纳米管导电手套的过程中,曲拉通的添加量太小会导致导电涂料晕染手套其他部位,而水性聚氨酯的添加量越大,面电阻越大附着力越好。
本发明所用的试剂和材料:曲拉通、十二烷基苯磺酸钠、硝酸、丙酮、碳纳米管均为分析纯。
附图说明
图1为普通手套和碳纳米管导电手套的示意图。
具体实施方式
下面结合具体实例对本发明作详细说明。
以纯度90%的单壁碳纳米管为导电物质,以水性聚氨酯为粘合剂配备水性涂料。在30 ml的小瓶中配备10 ml质量分数是0.1%的单壁碳纳米管溶液,加入100 mg的十二烷基苯磺酸钠,超声60 min制备碳纳米管分散液。把碳纳米管分散液倒入小烧杯中,低速机械搅拌下加入曲拉通和水性聚氨酯,使其浓度达到3wt%和0.5wt%,得到碳纳米管导电涂料。用喷枪将碳纳米管导电涂料喷涂到温度为130℃的手套基底上,烘干,小心浸入去离子水中浸泡10min,然后取出烘干,再用大量去离子水洗2遍,烘干就制备得到碳纳米管导电手套。
