Description

采用尼龙和碳纳米管的复合物的电缆扎带
与相关申请的交叉关系
本申请声索2013年10月15日提交的美国临时申请No.61/890,916的权益，其内容本文引用。
发明领域
本发明涉及具有改善的机械强度的电缆扎带。更具体地说，本发明涉及采用尼龙和碳纳米管的复合物的电缆扎带。
发明背景
电缆扎带是众所周知的，其可用于捆扎或固定诸如一束电线或电缆的物件。典型地，电缆扎带有头部、细长的尾部和在它们之间的纵向带状体。电缆扎带的头部有一个卡锁元件，把带状体与之相啮合就会把带状体固锁于头部。
电缆扎带一般有两种型式。第一种是一件式电缆扎带。一件式电缆扎带是用塑料，优选的是尼龙，整体成形的，它是用模制在头部里的一个卡爪和成形在带状体上一行齿来把带状体固锁固锁在头部里。第二种是两件式的电缆扎带。两件式电缆扎带有一个尼龙的头部和一个带状体。头部里埋置有一个不锈钢的倒刺，让倒刺挖进带状体，就能把带状体固锁在头部里
电缆扎带的性能用插入力来衡量，就是要用多大的力能把带状体插入头部。电缆扎带的性能还用它的张力来衡量。一般地，电缆扎带以它们的捆紧张力来分成等级(例如18磅、50磅、以及120磅)。电缆扎带的最大断裂极限是其最大额定捆紧张力的约150％。
一般地，电缆扎带只用尼龙6,6基料成形。尽管适用于预定的用途，但是，由于受尼龙6,6材料极限的限制，只用尼龙6,6制成的电缆扎带的机械强度有限。因此，需要开发具有提高的捆紧张力的电缆扎带。
发明内容
本发明提供一种包括聚合物和碳纳米管的复合物的电缆扎带以及这样的电缆扎带的制造方法。有利的是，与只用尼龙6,6成形的电缆扎带相比，这种电缆扎带有提高的拉伸强度。因此，这种改进的电缆扎带能够更好地绑扎住电缆束而在其被采用的应用场合达到更高的性能。令人满意的是，与现在用尼龙6,6成形的电缆扎带中再生的尼龙6,6的最大用量为25％重量比相比，这种电缆扎带允许再多用10-15％重量比的再生物料。此外，与用尼龙6,6成形的电缆扎带相比，这种电缆扎带有相同的或提高的耐火等级。
附图简要说明
图1以剖面图形式表示出本发明的一个示例性电缆扎带，它有头部和延伸的带状体，图中带状体已插入头部。
本发明的详细说明
参照图1，其表示出本发明的电缆扎带10。电缆扎带10典型地是一个细长的模制塑料件，其可被以本技术领域众所周知的方式用于捆扎一束物件，诸如一束电线或电缆(未示)。包括尼龙和碳纳米管的复合物的电缆扎带10既适于用在室外也适于用在室内。电缆扎带10有在其一端的头部12、在其另一端的尾部16、以及这两者之间的大体上平的带状体14。在给出的这一示例性实施例中，头部12是成形为电缆扎带10的整体组成部分。但在某些应用场合，电缆扎带10可能是由分别单独成形的头部12和带状体14构成。
电缆扎带10的头部12有一个通孔15(图中表示为带状体14插在其中)，其适应于尾部16以第一方向A插过和带状体14在其内穿过。电缆扎带10的头部12包括一个由头部12支承着并伸进通孔15的锁定装置18。锁定装置18允许带状体14沿第一方向A运动并能在有人企图从通孔15抽出带状体14时阻止带状体14沿第二方向B有实质性的运动。锁定装置18可以是一个金属的倒刺或一个整体成形的塑料卡爪，前者诸如美国专利No.5,513,421中所示的那种，后者诸如美国专利No.7,017,237中所示的那种。
本发明提供一种包括聚合物和碳纳米管的复合物的电缆扎带。在一个实施例中，聚合物是尼龙。在一个实施例中，聚合物是尼龙6,6。在一个实施例中，聚合物是尼龙6。在一个实施例中，聚合物是尼龙6,6/6。在一个实施例中，碳纳米管是被化学地功能化了的。在一个实施例中，碳纳米管是以0.05％到20％重量比之间的量存在于复合物中。在一个实施例中，碳纳米管是以0.05％到10％重量比之间的量存在于复合物中。在一个实施例中，碳纳米管是以0.05％到0.5％重量比之间的量存在于电缆扎带中。在一个实施例中，碳纳米管是以至少0.1％重量比的量存在于电缆扎带中。
在一个实施例中，电缆扎带还包括尼龙6,6树脂(除一种聚合物和碳纳米管的复合物外，其中聚合物也可以是尼龙6,6)。在一个实施例中，尼龙6,6是商业等级的尼龙6,6。在一个实施例中，尼龙6,6的至少一部分是再生的尼龙6,6。
在一个实施例中，电缆扎带还包括碳纤维。在一个实施例中，碳纤维以1％到10％重量比之间的量存在。在电缆扎带还包括碳纤维的一个实施例中，碳纳米管以0.05％到2％重量比之间的量存在于电缆扎带中。在某些实施例中，碳纤维在电缆扎带里的存在允许降低为达到想要达到的材料拉伸强度所需要的碳纳米管的量。
在一个实施例中，碳纳米管是以不大于约5％重量比的量存在于电缆扎带中。更具体地说，碳纳米管是以0.05％到约5％重量比之间的量存在于电缆扎带中。在一个实施例中，碳纳米管是以不大于0.5％重量比的量存在于电缆扎带中。虽然增加电缆扎带里碳纳米管的量能提高材料的拉伸强度，但取决于复合均匀性，电缆扎带里过量的碳纳米管可能导致一种非导电性损耗的电缆扎带，那样的电缆扎带不合乎某些应用场合的需要。
在一个实施例中，与用尼龙6,6基料制成的电缆扎带相比，本发明的这种电缆扎带表现出拉伸强度提高20％或更高。在一个实施例中，这种电缆扎带表现出拉伸强度比用尼龙6,6基料制成的电缆扎带提高20％以上。在一个实施例中，这种电缆扎带表现出拉伸强度比用尼龙6,6基料制成的电缆扎带提高30％或更高。
概括地说，本发明提供的电缆扎带的制造方法包括：a)用于合成尼龙和碳纳米管的复合物的化合技术，以及b)模制工艺技术，就是用a)中合成的尼龙和碳纳米管的复合物制造电缆扎带产品。
更具体地说，本发明提供电缆扎带的制造方法，这种方法包括：通过从溶解组合、熔化组合、以及原位(in-situ)组合技术选择的一种过程把碳纳米管分散于聚合物基料中，以形成化学键或与聚合物(例如尼龙6或尼龙6,6分子链)的范德瓦尔斯相互反应，从而形成一种复合物，这种复合物里包含0.05％到20％重量比之间的量的碳纳米管；把这种复合物挤压加工或模制加工成颗粒；熔化这种复合物颗粒，可选地与尼龙6,6一起熔化，而形成熔态的材料；以及用这种熔态的材料模制电缆扎带。在一个实施例中，复合物包括0.05％到10％重量比之间的量的碳纳米管。在一个实施例中，电缆扎带包含0.05％到0.5％重量比之间的量的碳纳米管。在一个实施例中，电缆扎带包括至少0.1％重量比的量的碳纳米管。在一个实施例中，电缆扎带包括不超过0.5％重量比的量的碳纳米管。在某些实施例中，先将复合物的颗粒与尼龙6,6树脂混合而后进行熔化。
在一个实施例中，这种方法还包括把碳纤维分散于聚合物基料中。在一个实施例中，碳纤维是以1％到10％重量比之间的量存在。在包含碳纤维的一个实施例中，碳纳米管是以0.05％到2％重量比之间的量存在于电缆扎带中。在包含碳纤维的一个实施例中，碳纳米管是以不超过0.5％重量比的量存在于电缆扎带中。
在一个实施例中，碳纳米管被均匀地分散在一种聚合物基料中。在一个实施例中，是先把碳纳米管化学地功能化，而后将其分散于一种聚合物基料。在一个实施例中，先用例如聚乙烯吡咯烷酮的表面活性剂物理地分离碳纳米管，而后将其分散于一种聚合物基料中。在某些实施例中，复合物的颗粒是小圆片、小圆球、小圆盘、不规则的几何形状、或它们之中两种或多种的混合。在某些实施例中，复合物颗粒的尺度约为0.1英寸。在一个实施例中，用标准的注塑机通过压注模制工艺成形电缆扎带，这是熟悉本技术领域的人通晓的。
在用尼龙6和碳纳米管的复合物成形的一个实施例中，先用一种表面活性剂(例如聚乙烯吡咯烷酮)把碳纳米管分散在一种水溶液里，而后与尼龙6粉末的水中分散物进行机械的混合。随后将形成的混合物从液相冷凝，然后把它熔化挤压加工成复合物小圆片。见例如O’Connell等人,Chem.Phys.Lett.,342,265(2001)。
在用尼龙6,6和碳纳米管的复合物成形的另一个实施例中，把酸化的碳纳米管机械地混合于尼龙6,6粉末来生产复合物小圆片。这样的复合方法是熟悉本技术领域的人通晓的。
在一个实施例中，先把碳纳米管复合于尼龙6，而后将得到的复合物化合于尼龙6,6，来生产用于模制电缆扎带的材料。
制造碳纳米管是采用熟悉本技术领域的人通晓的方法。单壁碳纳米管和多壁碳纳米管都适用。在一个实施例中，碳纳米管是多壁碳纳米管，例如直径在30到60nm之间、长度在1到5μm之间的原生多壁碳纳米管。在一个实施例中，碳纳米管是通过化学的蒸气沉积生产的。同样，化学地使碳纳米管功能化的过程(即形成被功能化了的碳纳米管)或物理地分离碳纳米管的过程(即用表面活性剂分离碳纳米管)也是熟悉本技术领域的人通晓的。此外，聚合物和碳纳米管的复合物是用熟悉本技术领域的人通晓的工艺过程形成的，诸如溶解组合、熔化组合、或原位组合技术。例如，Gao等人,“Continuous Spinning of Single-Walled Carbon Nanotube-Nylon composite Fiber,”Am.Chem.Soc.,127(11):3847-3854(2005)中描述了一种用尼龙和碳纳米管的复合物制成的纤维。类似地，用于制成颗粒的挤压技术和模制技术也是熟悉本技术领域的人通晓的，它们与用于成形电缆扎带的模制技术诸如压注模制相同。
尽管不想让本发明受任何理论的限制，但可以认为聚合物和碳纳米管的复合物中的碳纳米管起增强纤维的作用，其可以提高用这种复合物制成的电缆扎带的性能。尽管只用尼龙6,6制成的电缆扎带有足以适用于预定用途的机械强度，但与只用尼龙6,6成形的电缆扎带相比，含有碳纳米管和尼龙6,6的复合物的这种电缆扎带表现出更高的拉伸强度。
熟悉本技术领域的人能够理解，不偏离本发明的广泛的创造性概念，就可对上述实施例做出各种改变。所以，应能理解，本发明不限于这里揭示的具体实施例，而是应涵盖属于由权利要求书所定义的本发明的精神和范围内的各种变型。
