将密封材料暴露于油和/或高温可能引起材料特性上的不利改变诸如粘附性降低、机械强度降低、不希望的流动增加以及流动所引起的材料损失。
可商购获得的包含密封材料的产品被描述为由自粘型橡胶制成的乳香脂或乳香脂胶带。这些类型的产品应用于电工业中，诸如应用于输电和配电领域中。它们用于与实心电线的配件和边缘绝缘，并密封防止湿气进入。可将乳香脂材料折叠、拉伸、模塑成不规则形状以提供绝缘、水封和表面保护。已知它们提供一定程度的粘附性和耐化学品性以及防潮性，并且可用于与乙烯基胶带一起使用以达到最佳性能。
发明内容
一直需要在高温条件例如90℃下并且在烃类的存在下作用良好的乳香脂密封材料。这些条件存在于例如充油电缆(诸如纸绝缘的铅电缆(PILC))的接头和终端中，其中纸绝缘物浸渍有油。
本发明的至少一个实施例提供了密封材料，其包含：约20重量％至约70重量％的丙烯酸酯橡胶组分；约10重量％至约50重量％的流变性填料组分；约5重量％至约40重量％的增粘剂组分；约5重量％至约30重量％的增塑剂组分；约0.5重量％至约5重量％的抗氧化剂组分；至多约20重量％的电介质填料组分；和至多约20重量％的氟化热塑性或弹性体填料组分。
本发明的至少一个实施例的优点是在烃油的存在下，包括在高温下，保持防油密封件和防水密封件。
本发明的以上发明内容并不旨在描述本发明的每个公开的实施例或每种实施方式。以下附图和具体实施方式更具体地举例说明了示例性实施例。
具体实施方式
在以下的描述中，参考了构成本说明书的一部分的一套附图，其中通过举例说明的方式示出了若干具体的实施例。应当理解，在不脱离本发明的范围或实质的情况下可设想其它的实施例并进行实施。因此，以下的具体实施方式不应被理解成具有限制意义。
除非另外指明，否则说明书和权利要求书中所使用的所有表达特征尺寸、量和物理特性的数值在所有情况下均应理解成由术语“约”修饰。因此，除非有相反的说明，否则在上述说明书和所附权利要求书中列出的数值参数均为近似值，这些近似值可根据本领域的技术人员使用本文所公开的教导内容寻求获得的期望性能而变化。由端点表述的数值范围包括该范围内的所有数值(如，1至5包括1、1.5、2、2.75、3、3.80、4、和5)以及在此范围内的任何范围。
本发明的密封材料尤其可用于中电压或高电压电力电缆的接头和终端中。具体地，所述材料唯一地可用于充油电缆诸如纸绝缘的铅电缆(PILC)的接头和终端中，其中纸绝缘物浸渍有油。本发明的材料可单独使用，例如放置在半导电性减少的区域中电缆的绝缘层下，或者可与其它组分一起使用，例如作为冷收缩管的环境密封剂。本发明的密封材料有助于在烃油的存在下在高温高压下密封终端和接头内的空隙，从而防止油从电缆内部的丝毫渗漏，以及防止丝毫水渗入到电缆中。
本发明的材料通常通过将各成分混合然后将材料挤压、挤出、注塑、或压延成最终期望的形状来制备。最终产品可以如应用所期望的片材、成型制品、或呈腻子形式被提供。
本发明的密封材料可包含丙烯酸酯橡胶组分。该丙烯酸酯橡胶通常包含丙烯酸酯的单体或共聚物。合适的丙烯酸酯橡胶的非限制性示例包括丙烯酸甲酯、丙烯酸乙酯、丙烯酸丙酯、丙烯酸丁酯、丙烯酸戊酯、丙烯酸2-乙基己酯、丙烯酸辛酯、丙烯酸十二烷酯、丙烯酸氰乙酯等；和丙烯酸烷氧基烷基酯，包括例如丙烯酸甲氧基乙酯、丙烯酸乙氧基乙酯、丙烯酸丁氧基乙酯、丙烯酸乙氧基丙酯等；以及它们的组合。

丙烯酸酯橡胶组分通常包含约20重量％至约70重量％的密封材料。在一些实施例中，其包含约25重量％至约40重量％的密封材料。
本发明的密封材料可包含填料。可加入填料以影响诸如介电特性和流变特性等特性。为了本文的描述性目的，此类填料分别被分类为介电填料和流变性填料。然而，应当理解这些不是互相排斥的类别，并且被分类为介电填料的填料可影响流变特性，并且被分类为流变性填料的填料可影响介电特性。填料可具有任何合适的形状诸如球体、板、小片、立方体、针、扁圆、椭圆体、棱锥、棱柱、薄片、棒、纤维、碎片、须等，或它们的混合物。
可影响介电特性的填料包括导电材料、半导电材料和绝缘材料。合适材料的非限制性示例包括例如钛酸盐、氧化物、硼化物、碳化物、硅酸盐、氢氧化物、氮化物、钙钛矿、磷化物、硫化物、硅化物。更具体的示例包括钛酸钡、钛酸锶、钛酸锶钡、钛酸铜钙、二氧化钛、氧化锌、氧化锆、氧化镁、氧化铯、氮化硼、氧化铝、氧化硅(例如二氧化硅)、氧化铈、氧化铜、氧化钙、五氧化二铌、五氧化二钽、锆酸铅、钛酸铅锆、氧化锌、以及它们的组合。这些材料可为纯的或可诸如通过掺杂或加入其它成分来改性。其它合适的材料包括具有导电涂层的绝缘颗粒；金属和金属粉末，例如铝、金、银、铬、铜、钯、镍以及它们的合金；导电和非导电碳粉末，包括但不限于炭黑、N110、N990、碳纳米管和石墨。可商购获得的炭黑的示例包括但不限于以商品名BP2000、VXC7、VXC605、R660和VULCANXC72得自美国卡伯特公司(CabotCo.,USA)；以商品名ENSACO150G、ENSACO260G和ENSACO250G得自比利时的特密高石墨和碳公司(TIMCALGraphites&CarbonCorp.,Belgium)的那些。在本发明的许多实施例中，炭黑是优选的介电填料。
介电填料通常包含至多约20重量％的密封材料。在一些实施例中，其包含至多约10重量％的密封材料。
可影响流变特性的填料的非限制性示例包括粘土、纳米粘土、滑石、无机盐(诸如碳酸钙)、氢氧化物(诸如氢氧化镁)、无机氧化物(诸如氧化镁)、以及硅酸盐(诸如硅酸镁、硅酸铝)和二氧化硅。一些二氧化硅，诸如可以商品名SACAC5从巴西的ItatexEspecialidades矿物质公司(ItatexEspecialidadesMinerais,Brazil)获得的那些，抑制在使材料经受高温时可能发生的油(液体)释放。
流变性填料通常包含约10重量％至约50重量％的密封材料。在一些实施例中，其包含约15重量％至约40重量％的密封材料。
本发明的密封材料可包含增粘剂。合适增粘剂的非限制性示例包括萜烯树脂、萜烯酚醛树脂、α-蒎烯苯酚树脂、酯化的松香和部分聚合的松香、腈橡胶等。
增粘剂可调控材料的流变特性，诸如例如粘着性、粘附性和可润湿性。增粘剂树脂可用于通过降低粘度、增大未硫化混合物的粘着性以及有助于聚合物自动融合来增强材料的工作能力。
增粘剂树脂通常具有一般介于500和2,000之间的分子量和介于50℃和150℃之间的软化点。增粘剂树脂包括沥青衍生物、萜烯、石油烃树脂和改性酚醛树脂。
为了显著增大材料的粘附能力(粘着性)，可能期望使用具有低软化温度的树脂。然而，为了获得具有耐高温性的材料，通常需要具有更高软化温度的增粘剂树脂。当将本发明的组合物在经受大约90℃或更高温度的应用中使用时，特别合适的增粘剂树脂通常表现出通过环和球试验(ASTMD3461-76方法)测量的在约90℃至约150℃范围内的软化温度。
增粘剂通常包含约5重量％至约40重量％的密封材料。在一些实施例中，其包含约10重量％至约30重量％的密封材料。
本发明的密封材料可包含增塑剂。合适增塑剂的非限制性示例包括芳族基油；柠檬酸酯；环状烯烃(诸如聚环戊二烯)；聚α-烯烃(诸如氢化聚合的癸烯-1)、氢化的三联苯或其它萜烯衍生物；聚氧化丙烯单酯和二酯、环戊二烯共聚物与脂肪酸酯；磷酸酯和单酯、二酯及聚酯(诸如苯三甲酸酯、邻苯二甲酸酯、苯甲酸酯、脂肪酸酯衍生物、脂肪酸酯醇、二聚酸酯、戊二酸酯、己二酸酯、癸二酸酯、聚合物聚酯、松香酯、丙烯酸酯、环氧化脂肪酸酯等)、聚酯和聚醚诸如己二酸酯、邻苯二甲酸酯、壬二酸酯等，例如邻苯二甲酸二辛酯和壬二酸二辛酯，以及它们的混合物。
增塑剂通常包含约5至约30重量％的密封材料。在一些实施例中，其包含约10重量％至约20重量％的密封材料。
本发明的密封材料可包含抗氧化剂。合适的抗氧化剂的非限制性示例包括受阻酚，诸如可以商品名IRGANOX1010从德国的汽巴公司(Ciba,Germany)(现在是巴斯夫公司(BASF)的一部分)获得的那些；和受阻胺，诸如可以商品名NAUGARD445从英国的ChemturaEurope,Ltd.获得的那些；和二苯二硫。
抗氧化剂通常包含约0.5重量％至约5重量％的密封材料。在一些实施例中，其包含约0.5重量％至约1重量％的密封材料。
本发明的密封材料可包含四氟乙烯低聚物和聚合物诸如聚四氟乙烯(PTFE)。本发明的至少一个实施例包括粉末PTFE。据信，粉末PTFE在混合期间纤丝化。另外据信，纤丝化的PTFE有助于将材料保持在一起并影响其流动特性，从而提供结构支撑和弹性。另外据信，PTFE至少部分地提供了具有耐撕裂性和耐溶剂性特性但不显著增大其粘度(粘度的增大将不利地影响密封材料的挤出和模塑)的材料。
氟化热塑性或弹性体填料通常包含至多约20重量％的密封材料。在一些实施例中，其包含至多约5重量％的密封材料。
本发明的密封材料可包含其它添加剂，取决于材料的期望特性以及其它因素诸如处理方法和条件。其它添加剂的示例包括染料、颜料、阻燃剂、释放助剂等，只要添加剂不负面地影响密封材料的介电特性即可。
本发明的密封材料优选地具有介于约3和约40之间的介电常数，和介于约0.005和约1之间的介电损耗，这使得其适合用于电力电缆接头和终端中。密封材料优选地具有低于约10％，更优选低于5％，并且最优选低于1％的吸油量，这使得其特别适合与充油电缆诸如纸绝缘的铅电缆(PILC)一起使用，其中该纸绝缘物浸渍有油。
本发明的密封材料优选地具有在室温下约65KPa至约130KPa(约23℃)和在50℃下约50KPa至约120KPa的弹性模量。本发明的密封材料优选地具有在23℃下约5％的最小弹性恢复率。这些特性使得密封材料在施用期间容易地处理，表现类似于胶带，而且还可在储存期间耐受高温。本发明的密封材料优选地具有对不锈钢至少约3kg/m、对铜至少约6kg/m、以及对铅至少约80kg/m的180°剥离强度，这使得其适于与各种类型的电力电缆一起使用。

材料列表
样品制备
实例1-7的乳香脂材料的组成提供于表1中。表1中的所有量均按重量百分比计。通过在室温下将丙烯酸酯橡胶、粘土、炭黑、增粘剂、抗氧化剂和聚四氟乙烯加入班伯里密炼机中并以100rpm混合5分钟来制备乳香脂材料。将温度升至240℉(115℃)，并且将混合速度降至40rpm。加入增塑剂并混合1分钟。将混合速度增大至120rpm，并且将乳香脂材料混合5分钟。当材料的温度达到220℉(104℃)时，混合完成，并且将材料从密炼机中取出。
表1：
在150℉(66℃)的液压机中通过将乳香脂材料夹置在有机硅涂布纸的片材之间并挤压成100密耳(2.5mm)的厚度来模塑用于测量电特性和耐油性的样品块。将用于施用到电缆接头上的乳香脂样品挤出通过150℉(66℃)的狭缝模具以产生具有宽度为约1"(2.5cm)且厚度为100密耳(2.5mm)的连续乳香脂条。随着乳香脂被挤出，两侧覆盖有有机硅涂布纸。
将用于粘合测试的乳香脂样品挤出在两片衬垫之间到宽度为约0.75"(19mm)宽且厚度为100密尔(2.5mm)的条中，然后切割成长度为5.0"(12.7cm)的件。从乳香脂的一侧移除衬垫，将乳香脂放置在金属表面上，并使用51b辊的一遍扫描向乳香脂的衬垫覆盖侧施加压力。将金属板的一端夹在MTS张力测试仪的下钳口中。从金属板剥离乳香脂条的底端的大约0.5"长的部分，并将其粘结到聚酯胶带条以制备6”引线。将聚酯夹到用于180°剥离强度测量的MTS张力测试仪的上钳口中。
用于动态力学分析(DMA)和弹性恢复测试的样品通过如下方法来制备：在200℉(93℃)的液压机中将材料挤压成适当厚度(对于DMA，3mm；对于弹性恢复，1.5mm)的块。使用具有25mm直径的模具从块上切出圆盘。
测试方法
介电常数(相对诱电率，κ)和介电损耗(电损耗因数，tanδ)使用ASTM-D150-2004，“用于固体电绝缘物的AC损耗特性和电容率(介电常数)的标准测试方法(StandardTestMethodsforACLossCharacteristicsandPermittivity(DielectricConstant)ofSolidElectricalInsulation)”中指定的程序进行测量。
吸油量的程度通过将2"×4"(5cm×10cm)的已知重量的乳香脂条浸没在194℉(90℃)的聚丁烯油中4天进行测量。将样品从油中取出，去除过量的油，并将样品称重。在浸没后以重量增加百分比计算吸油量。
乳香脂材料密封PILC电缆的接头区域以及在高电压条件下执行的能力使用IEEE-404，“额定2.5kV-500kV的挤出和层压介电屏蔽电缆接头(ExtrudedandLaminatedDielectricShieldedCableJointsRated2.5kVto500kV)”进行评估。
使用DMA来确定作为温度函数的储能模量(G’)和损耗模量(G”)，利用的是Rheometrics型RSA-2固体动态机械分析仪。圆盘形乳香脂样本在1Hz的恒定频率下以5℃/min的加热速率在平行板模型中进行测试。
乳香脂样品在施加恒定压力后恢复弹性的能力如下进行测量。将圆盘形样本放置在有机硅涂布纸防粘衬垫的片材之间。然后将具有防粘衬垫的样品放置在两块铝板之间，并且将78psi(0.54MPa)的气动压力施加在两板之间并持续30秒的时间。释放压力，移除防粘衬垫，并立即测量直径(d初始)。使该样品在室温下静置1小时，之后测量最终直径(d最终)。对于高温测试，将样品夹置在防粘衬垫片材之间，放置在两块铝板之间，然后放置在烘箱中并持续30分钟。将样品从烘箱中取出，立即在两板之间施加30psi(0.21MPa)的压力并持续30秒的时间段。释放压力之后，移除防粘衬垫并立即测量直径(d初始)。使该样品在室温下恢复1小时，之后测量最终直径(d最终)。据观察，大部分的恢复在移除压力后的前几分钟内发生。恢复率百分比使用下式由所测量的直径进行计算：(d初始-d最 终)/(d初始)。
乳香脂与各种金属表面的180°剥离强度使用MTS张力测试仪以12”/min的牵拉速率进行测量。使用不锈钢、铜、和铅的基底，并且记录最大剥离力。
结果
电测试结果提供于表2中。
表2：
| 实例 | 介电常数，K | 介电损耗，ΤΑΝδ |
| 1 | 5.15 | 0.046 |
| 2 | 5.51 | 0.046 |
| 3 | 8.1 | 0.088 |
| 4 | 19.5 | 0.31 |
| 5 | 12.00 | 0.14 |
乳香脂实例3的吸油量被确定为0.20重量％。低吸油量是用于PILC应用的乳香脂材料的积极属性。相比之下，一些材料(诸如二氧化硅)吸收高达10-50％的油。
乳香脂实例5用于PILC3-芯接头中以密封分叉区域以及3通引导(3-wayboot)的端部。接头通过了根据IEEE-404的短期测试和长期测试两者。
乳香脂实例6和7的DMA测试结果提供于表3中，其比较了含有PTFE(实例7)的乳香脂样品和不含PTFE(实例6)的乳香脂样品的弹性模量(G’)值。在介于30℃和70℃之间的温度下，实例7展示出比实例6高的弹性模量。然而，在介于80℃和190℃的温度下，实例6和实例7的G’值是相似的。
表3：
乳香脂实例6和7的弹性恢复测试结果提供于表4中。在每一种所测试的温度下，实例7(其包含PTFE)展示出比实例6(其不包含PTFE)高的恢复率。
表4：
乳香脂实例5对于不锈钢、铜和铅的180°剥离强度测量提供于表5中。
表5：
