Description

复合增强体
技术领域
本发明涉及一种用于弹性体制品、特别地用于充气车辆轮胎的带状包带的强度构件，其中该强度构件是一种复合帘线，该复合帘线包括至少一种具有不超过100mN/(tex·％)的弹性模量的低模量纱线和至少一种具有不少于200mN/(tex·％)的弹性模量的高模量纱线，它们各自是在3％的伸长率下根据ASTM D885M，其中该复合帘线的所有纱线折叠在一起并且其中该复合帘线被提供了一种粘合剂浸渍。本发明进一步涉及一种生产此类强度构件的方法，其中该强度构件是一种复合帘线，该复合帘线包括至少一种具有不超过100mN/(tex·％)的弹性模量的低模量纱线和至少一种具有不少于200mN/(tex·％)的弹性模量的高模量纱线，它们各自是在3％的伸长率下根据ASTM D885M，其中该复合帘线的所有纱线折叠在一起，其中将一种粘合促进剂施加至该复合帘线上，其中然后在从100℃至200℃的温度下干燥该复合帘线，其中在干燥之后在从200℃至250℃的温度下热拉延该复合帘线，并且其中该复合帘线在热拉延之后在剩余应力下在从100℃至200℃下松弛。本发明进一步涉及此类强度构件的用途。
背景技术
在充气车辆轮胎中提供了一种带状包带以阻止在驱动过程中、特别地在高速运行过程中来自离心力的轮胎的膨胀。一种以子午线设计的充气车辆轮胎总体上包括一个不透气内层、子午线胎体(该子午线胎体包含强度构件并且通过侧壁从该轮胎的顶点区域延伸至该胎圈区域中并且通常通过包裹在抗拉胎圈芯周围进行锚固)、径向外部成形胎面带和在该胎面带与该胎体之间的带，所述带由该带状包带径向外部地覆盖。该带状包带可具有一种单层或多层配置并且覆盖至少该带边缘。该带状包带典型地包含以嵌入至橡胶中的帘线的形式实质上周向延伸的强度构件的一种平行安排。
在轮胎生产中，该带状包带以层、带或单类型强度构件的形式施加，这些单类型强度构件包括嵌入至一种橡胶的未固化混合物中的被卷绕或缠绕在该带上的强度构件。这些强度构件通过基本上平行的线形强度元件的片嵌入在该橡胶中，这些强度构件总体上被提供一种用于更好地附着到该嵌入的橡胶的粘合剂浸渍，从而在纵向方向上通过一个压延机或挤出机用于用该橡胶混合物覆盖。
该带状包带的强度构件旨是在轮胎生产过程中在成形阶段下并且还在该固化模具中允许足够的膨胀目的，以便该轮胎可以是精密成形的，并且它们旨在确保(一旦该轮胎完成)在运行中的良好的高速效力。为了满足这些要求，这些强度构件应该具有对于轮胎制造足够的断裂伸长率并且在中等力下可延伸最高达约3％至4％的应变并且仅仅在非常高的力下可延伸更高的应变。
非常多种多样的帘线已经作为用于该带状包带的强度构件被提出。DE 10 2006031 780 A1例如提出了以下带状包带的强度构件，这些强度构件是复合帘线，这些复合帘线由一种由芳族聚酰胺制成的第一纱线(具有≤840dtex的细度)构建造并且与另一种纱线折叠在一起，所述纱线是由尼龙制成的并且具有≤940dtex的细度。
在从DE 10 2007 025 490 A1已知的用于充气车辆轮胎的带状包带的复合帘线中，该复合帘线是由两种加捻的纱线形成的，一种纱线是一种具有≤1680dtex的细度的芳族聚酰胺纱线并且该第二纱线是一种具有≤1670dtex的细度的PES纱线。
在此类复合构造中，一种高模量纱线与一种低模量纱线进行加捻并且从而提供一种螺旋路径以便给予其用于该复合帘线中的几何伸长率的范围。这赋予了可伸展性，由此弹性模量对于小变形是相对小的并且通过比较对于较大的变形是相对较大的。这种类型的力-伸长率行为允许在轮胎成形和轮胎固化中的膨胀并且致使该轮胎高速有效。
然而，在所引用文件中明确地报道的示例性实施例所有仅仅披露了由具有各自不小于840dtex的细度的纱线构造的复合帘线。在细度上的减少总体上导致减小的强度，并且因此甚至一个相当小的负荷可引起在运行中或在轮胎制造的过程中强度构件的破裂。
本领域另外转移至具有最小的滚动阻力的充气车辆轮胎的方向。
发明内容
由本发明解决的问题是提供一种用于弹性体制品、特别地用于充气车辆轮胎的带状包带的强度构件，当在该充气车辆轮胎的带状包带中使用时，该强度构件减少所述充气车辆轮胎的滚动阻力而同时确保其耐久性并且允许一种无故障的轮胎建造和固化。由本发明解决的问题还是提供一种用于生产此类强度构件的方法。
当该一种或多种低模量纱线具有不超过550dtex的累积细度、优选地不超过250dtex的累积细度时，当该一种或多种高模量纱线具有不超过550dtex的累积细度、优选地不超过250dtex的累积细度时，并且当该复合帘线具有不少于5％的断裂伸长率时，该问题得以解决。
包含此类复合帘线作为强度构件的强度构件层当用于一种充气车辆轮胎中时对于特别低水平的滚动阻力是值得注意的。该复合帘线比较高细度的复合帘线具有较低的细度并且因此较低的截面。这使得有可能提供对于较低的厚度是值得注意的强度构件层。此外，节省了强度构件材料和/或橡胶处理。这减少了滞后以及重量。当用于充气车辆轮胎、特别是带状包带中时，因此实现了减少水平的滚动阻力，同时保持复合类型强度构件的剩余有利的特性。橡胶处理的减少的厚度还节省了材料成本。
出人意料地，发现在该轮胎中此低细度的此复合帘线具有力-伸长率行为外加足够的强度，其中减少的模量通过在织物中的增加支数的帘线进行补偿。这确保了用于包括此复合帘线作为该带状包带的强度构件的充气车辆轮胎的足够耐久性并且允许一种无故障的轮胎建造和固化。
本发明因此提供了一种低细度的复合帘线，该复合帘线作为一种用于弹性体制品的强度构件、特别地作为一种用于充气车辆轮胎的带状包带的强度构件是非常有用的。
一种特别有用的粘合剂浸渍是一种RFL浸渍液(间苯二酚—甲醛胶乳浸渍)，用该浸渍液浸渍该强度构件用于在该橡胶与该强度构件之间的附着。可以按照1-浴或2-浴浸渍方法施加该浸渍。
出于本发明的目的，“帘线”是由两种或多种折叠在一起的纱线组成的线性构造。“复合帘线”是折叠在一起的两种或多种纱线为不同的帘线。在此“纱线”是与DIN 60900一致的一种由单独细丝或纤维组成的线性构造。这些纱线的细丝或纤维优选地是加捻在一起的。一种以一种材料的纱线完全或部分是由这种材料形成的。帘线的细度典型地计算为构成该帘线的纱线的细度的总和。
“断裂伸长率”是在极限拉伸力下的伸长率，即，在导致该复合帘线断裂的力下的伸长率。断裂伸长率是根据ASTM D885M测量的。
所有的强度构件层的强度构件优选的是此复合帘线。
对于该复合帘线的该一种或多种高模量纱线还优选的是具有不超过250dtex的累积细度。优选地，在这个实施例中，该一种或多种低模量纱线的累积细度具有不超过250dtex的累积细度。
对于该复合帘线有利的是包括一种以聚酯(PES)的低模量纱线和/或一种以聚酰胺(PA)的低模量纱线。
根据本发明的复合帘线的聚酯纱线(以PES的纱线)是一种HMLS聚酯纱线(高模量低收缩率)和/或一种HMHS聚酯纱线(高模量高收缩率)和/或一种HMNS规则的聚酯纱线(高模量正常收缩率)。优选地是一种所使用的HMLS聚酯纱线和/或HMNS规则的聚酯纱线。这些纱线具有良好水平的热稳定性，完全与在提及的应用中的要求一致，例如，在充气车辆轮胎中的应用上的高速效力。
有利地，聚酯纱线的聚酯(PES)选自下组，该组由以下各项组成：聚对苯二甲酸乙二酯(PET)和/或聚萘二甲酸乙二酯(PEN)和/或聚对苯二甲酸丁二酯(PBT)和/或聚碳酸酯(PC)，其形式上可以被认为是一种聚酯。PEN和/或PET的使用是优选的并且PET的使用是特别优选的。PET具有超过PEN的一个优点，因为它是相对廉价的。PET聚酯优选地是以HMLS和/或HMNS规则的PET的形式使用。
有利地，以聚酰胺的纱线的聚酰胺选自下组，该组由以下各项组成：聚酰胺6(PA6)和/或聚酰胺66(PA 66)和/或聚酰胺12(PA 12)和/或聚酰胺11(PA 11)和/或聚酰胺1313(PA 1313)和/或聚酰胺4(PA 4)和/或聚酰胺7(PA 7)和/或聚酰胺8(PA 8)和/或聚酰胺9(PA 9)和/或聚酰胺46(PA 46)和/或聚酰胺610(PA 610)和/或聚酰胺612(PA 612)和/或聚酰胺69(PA 69)和/或聚酰胺66/6(PA 66/6)。PA 6和/或PA 66的使用是优选的并且PA 66的使用是特别优选的。
如果在该带状包带中使用，以PA的纱线和以PES的纱线由于它们在低伸长率下的收缩有助于平斑(flatspotting)的不利现象。在充气车辆轮胎的强度构件层中的这些强度构件材料的减少水平因此导致在抗平斑和尺寸稳定性上的一种改进。
对于该复合帘线有利的是包括一种以芳族聚酰胺的高模量纱线和/或一种以碳的高模量纱线和/或一种以玻璃的高模量纱线。这些材料作为该复合帘线的高模量组分是非常有用的。芳族聚酰胺和碳对于获得是成本密集的。减少这些强度构件材料的水平因此降低材料的成本。
在有利的发展中，该复合帘线是由一种以芳族聚酰胺的纱线和另一种以PES的纱线、或者由一种以芳族聚酰胺的纱线和另一种以PA的纱线构造的。此类简单的帘线构造提供了一种复合帘线，该复合帘线当例如在充气车辆轮胎中使用时，结合必要的强度与非常良好的抗平斑和滚动阻力特性。
在一种优选的发展中，该复合帘线包括一种具有不超过220dtex的细度的芳族聚酰胺帘线。此类强度构件的使用提供了一种具有结合了良好的强度与相对低的高度的强度构件层的弹性体制品。这附加地导致低的材料成本并且当在充气车辆轮胎中使用时一种优化水平的滚动阻力。
该以芳族聚酰胺的纱线优选地具有220dtex的细度。优选地，一种220dtex芳族聚酰胺纱线与另一种235dtex细度的以PA 66的纱线或者与一种238dtex细度的以HMLS-PET的纱线折叠在一起。这种类型的强度构件层值得注意的是特别低的高度。优选地，该芳族聚酰胺纱线还可以与另一种470dtex细度的以PA 66的纱线或者与一种550dtex细度的以HMLS-PET的纱线折叠在一起。这种类型的复合帘线值得注意的是高的断裂伸长率。
在构成复合帘线的纱线的细度上的差异应该保持一个最小值以获得一种非常均匀且对称的帘线，该帘线具有良好的加工特性和良好水平的残留强度(在疲劳之后)。对于构成该帘线的纱线有利的是具有非常相似的细度水平。在这方面所已经发现特别有利的是一种由220dtex芳族聚酰胺纱线和另一种235dtex下的以PA 66的纱线和/或另一种238dtex下的以HMLS-PET的纱线构成的复合帘线。
在其他有利的发展中，这些复合帘线是由三种、四种或更多种折叠在一起的纱线构造的。对于这些复合帘线优选的是由一种或两种以芳族聚酰胺的纱线和两种另外的纱线构造的，这些另外的纱线两者是由PES或PA或另一种PES的纱线和另一种PA的纱线两者形成的。
有利地，该复合帘线的纱线使用80至200的捻系数α折叠在一起。这种捻系数α被定义为α＝捻[捻数/m]·(细度[tex]/1000)1/2并且是一种相对于该帘线的细度每米捻数的度量。在α<80下，抗疲劳性急剧下降，这可导致帘线断裂。在α>200下，相比之下，强度急剧下降，同时存在在加工成本上的递增上升。优选地，该复合帘线的纱线使用从100至150的捻系数α折叠在一起。
对于在该强度构件方面的高断裂伸长率，对于该复合帘线有利的是在不超过60mN/tex的拉伸应力下、优选地在不超过40mN/tex的拉伸应力下被热拉延。这可以在粘合剂浸渍的过程中发生。
为了确保包括固化的无故障轮胎建造加上良好的高速效力，在3％伸长率下根据ASTM D885M该复合帘线的弹性模量是从80mN/(tex·％)至300mN/(tex·％)、优选地从100mN/(tex·％)至200mN/(tex·％)。
该问题因为它涉及该生产方法在以下时解决，当
-该一种或多种低模量纱线具有不超过550dtex的累积细度、优选地不超过250dtex的累积细度，
-该一种或多种高模量纱线具有不超过550dtex的累积细度、优选地不超过250dtex的累积细度，
-在干燥过程中将该复合帘线暴露于从5至50mN/tex的拉伸应力、优选地暴露于从10mN/tex至30mN/tex的拉伸应力，并且
-将该复合帘线暴露于从10mN/tex至60mN/tex的拉伸应力、优选地暴露于从15mN/tex至40mN/tex的拉伸应力，同时经受热拉延，并且
-该复合帘线在从0mN/tex至30mN/tex、优选地从3mN/tex至15mN/tex的拉伸应力下松弛。
本发明的强度构件是用此类方法可获得的。所产生的复合帘线具有低水平的细度。出人意料地，在该粘合剂浸渍过程的干燥、热拉延和松弛阶段中经历了非常低水平的拉伸应力的此类低细度的复合帘线具有高的断裂伸长率、特别是不少于5％的断裂伸长率。其断裂伸长率高于一种可比较的复合帘线的断裂伸长率，但是该可比较的复合帘线在该粘合剂浸渍过程期间暴露于较高水平的拉应力。这使得有可能提供一种用于弹性体制品、特别地用于充气车辆轮胎的带状包带的强度构件，在充气车辆轮胎的带状包带中使用该强度构件时，该强度构件具有低的细度以减少该充气车辆轮胎的滚动阻力，而同时保护该充气车辆轮胎的耐久性并且使能够无故障的轮胎建造和固化。
当该低模量纱线是一种以聚酯或聚酰胺的纱线时和/或当该高模量纱线是一种以芳族聚酰胺或玻璃或碳的纱线时，获得了一种有利的复合帘线。
实现与橡胶的可靠附着的一种有利的方式是所使用的粘合促进剂是间苯二酚—甲醛胶乳(RFL)、一种异氰酸酯类型的粘合剂系统或环氧树脂。
对于该复合帘线的该一种或多种高模量纱线还优选的是具有不超过250dtex的累积细度。优选地，在这个实施例中，该一种或多种低模量纱线的累积细度具有不超过250dtex的累积细度。
对于该复合帘线还优选的是由一种以芳族聚酰胺的纱线和另一种以PES的纱线、或者由一种以芳族聚酰胺的纱线和另一种以PA的纱线构造的。当该复合帘线包括一种具有不超过250dtex的细度、优选地具有不超过220dtex的细度的芳族聚酰胺纱线时，也是优选的。
当以上描述的复合帘线被用作一种在另外的弹性体制品(如一种充气车辆轮胎、传送带、传动皮带、软管和/或空气弹簧瓣)中的强度构件时，它是减少的强度构件层的高度同时外加产生优点的有利力-伸长率行为。
当使用一种以上描述的复合帘线作为一种充气车辆轮胎的带状包带的强度构件时，该轮胎具有改进的耐久性并且使得一种无故障的轮胎建造和固化以及还有减少水平的滚动阻力可能。
具体实施方式
本发明的示例性实施例以及另外的优点现在将连同表1至3更具体地描述。
表1给出了根据本发明的复合帘线的一些实例，这些实例被称为复合帘线I、II、III和IV。所述复合帘线各自包括在550T/m下Z-加捻的220dtex芳族聚酰胺纱线。这些复合帘线各自包括另一种在550T/m下Z-加捻的纱线。这两种纱线在550T/m下在S-方向上折叠在一起以形成该复合帘线。该复合帘线I的另一种纱线是一种470dtex细度的以PA 66的纱线，该复合帘线II的另一种纱线是一种235dtex细度的以PA 66的纱线，该复合帘线III的另一种纱线是一种550dtex细度的以PET的纱线并且该复合帘线IV的另一种纱线是一种238dtex细度的以PET的纱线。
表1
这些复合帘线被提供一种RFL浸渍作为粘合剂浸渍。在粘合剂浸渍的工艺中，然后将该复合帘线在100℃至200℃的温度下在一个拉伸应力下进行干燥，其后在200℃至250℃的温度下在一个拉伸应力下进行热拉延，并且在热拉延之后，在从100℃至200℃下在一个拉伸应力下进行松弛。在每种情况下拉伸应力被报道于表2中。
表2
上述的复合帘线按照ASTM D 855M用于获得力-伸长率数据，这些数据示出于表3中。复合帘线均具有不少于5％的断裂伸长率。
表3
此复合帘线的低细度使得可能生产用于弹性体制品的薄的强度构件层。当此类强度构件用于该充气车辆轮胎的带状包带中时，因此减少了该充气车辆轮胎的滚动阻力。然而，尽管低的细度，但是保护了耐久性并且确保了一种无故障的轮胎建造和固化。
