Description

用于生产复合织物材料的方法和覆盖有复合织物材料的传 动带
技术领域
本发明涉及一种用于生产用于覆盖传动带的片状复合织物材料、特别是用橡胶处理的织物或具有聚合物制剂的织物的方法，该复合织物材料包括整合在弹性体材料基质中的纺织品、优选地包括整合在橡胶基质中的至少一个织物层。本发明同样涉及一种传动带，其具有以这种方式生产的织物复合材料的覆盖物。
背景技术
在复合材料中，基质是通常用于指代其中嵌入其他成分的材料的术语。“橡胶处理”是通常用于指代纺织品在橡胶混合物或聚合物制剂中的整合的技术术语。术语“覆盖”在此是指将复合织物材料施加于制品(例如传动带)表面以及复合织物材料与制品表面的相应合适的连接点。术语“混合物”在此用作由橡胶和/或其他聚合物构成或包括橡胶和/或其他聚合物的任何混合物的指示。
传动带(也就是例如V形带、多V形带或齿形带)常常在其外侧设有织物层，这显著改进了在传动带操作期间传动带与传动带轮之间的摩擦和磨损的条件。此类织物通常具有各种橡胶或其他聚合物制剂，以改进粘合剂粘接、防止磨损、和油不渗透性。
使用多种多样的方法来生产这些织物。生产它们的一种可能性是将织物浸入橡胶溶液/橡胶混合物溶液或粘接剂溶液中。然而，为此，首先必须相对费力地制备相应的溶液，并且然后必须花费相当多的能量来干燥织物。另外，可以加工的量受到溶液量的限制。
由于这些溶液具有溶剂，因此还需要相对费力的废气清洁。此外，这些溶剂的蒸发在纺织品复合材料或复合材料中留下孔，使得存在织物未完全填充的风险。而且不总是确保溶剂的所有部分从形成基质的材料中蒸发出来并且例如它们不保留在基质中。
出于工艺相关的原因，具有很大的纵向可延展性的纺织品不能用于此。这些被理解为意指用宽度为5cm的纺织品条测量时在100N的拉伸应力下具有超过50％伸长率的纺织品。例如通过对经长丝进行织构化(例如通过假捻卷曲方法或通过使用弹性长丝)来生产具有很大的纵向可延展性的纺织品(也称为纵向可拉伸纺织品)。
此外，利用以上列出的方法，每种操作中只有一种材料可用作织物/复合材料的基质形成剂。
在铺展的情况下(其中聚合物或橡胶糊或基于聚合物或橡胶混合物的糊通常铺展开)和在压延的情况下都存在类似的缺点。压延是用于以下工艺的术语，在该工艺中，辊用于将混合物片或混合物垫压制成另一片状结构或用于将混合物片或混合物垫连接到另一片状结构。在此所讨论的生产复合织物材料的情况下，这将是通过辊被整合到织物层中的混合物片材。在压延的情况下，可能不利地发生的是，通过将混合物片放置在表面上而使得纺织品或织物层没有很好地充分填充，或者混合物渗透到织物层中的深度太小(这当然取决于混合物的粘度)。
另一种可能性是通过所谓的“摩擦”进行生产，其中橡胶或聚合物混合物通过机械轧制加热，最终借助于辊子被热捏合并被驱动到纺织品中。在此种情况下，施加的量不利地受到限制，并且在每次操作中也可以仅施加一种材料。这里，基质材料也可能仅被驱动到最上面的纺织品层中，并且因此填充不充分。此外，纺织品或织物层当然经受很大的拉伸力，使得在此也几乎不能使用具有很大的纵向可延展性的纺织品。
发明内容
因此，本发明的目的是提供一种用于生产复合织物材料、特别是用于覆盖传动带的织物的方法，该方法没有所提及的缺点，确保该复合材料的无孔且无溶剂基质(这允许在一次操作中引入多种材料)，减少溶剂并且简化生产工艺中设备和人员的耗费。
此目的是通过主权利要求的特征来实现的。在从属权利要求中披露了进一步有利的配置。同样披露了一种具有根据本发明生产的复合材料的覆盖物的传动带。
在根据本发明的方法的情况下，纺织品或织物层和弹性体材料被引入带与圆柱形模制轮之间的间隙中并且在低于硫化温度的温度下被模制以在带与模制轮之间形成复合材料，该带在此压力下以卷绕角围绕该模制轮卷绕，使得弹性体材料渗透到纺织品或织物层中，使得获得完全渗透并且纺织品或织物层的纱线完全整合在弹性体材料中。在此有利的压力在从2至6巴的范围内。
出人意料地，甚至具有很大的纵向延伸的纺织品(纵向可拉伸的纺织品)通过根据本发明的方法连接到例如橡胶或聚合物基质，使得纵向可延展性也基本上保留在复合材料中，纺织品完全整合在基质中(即填充有基质材料)。围绕模制轮的卷绕角可根据方法的执行而适配，并且通常超过180°。
以这种方式生产的片状复合织物材料(例如用橡胶处理的织物层)的优点在于所有纱线和拉伸股线都被周围的弹性体材料保护并且被整合在基质中。具有这种织物层的传动带在此织物层与其他材料之间也具有很大的粘合剂粘接。例如，在操作上温热的油中运行的齿形带的情况下，纺织品或织物层被根据本发明的生产方法很好地保护，使得在这种侵蚀性条件下的运行时间和寿命显著增加。
根据本发明的方法可以通过转回到现有的已知的生产装置而特别容易地实现，该生产装置可以通过其生产顺序的简单改变而适配于所要求保护的方法。有利地，纺织品或织物层和弹性体材料因此可以被引入旋转硫化装置(AUMA)的带与圆柱形模制轮之间，并在那里被模制以形成复合材料，然后该带的温度控制和支承压力当然被设计成使得没有完全硫化，但是仍然发生织物的完全渗透。
这样的旋转硫化装置例如在DE 1 931 972 A、DE 26 55 025 C2和DE 10 2013102 148 A1中披露，但是其中描述了使用挤出的基础材料的旋转硫化方法。其中，为了生产弹性牵引装置/传动带坯料，在挤出期间，拉伸构件进入出口模中挤出的、仍然温暖且相对粘稠的材料。具有因此产生的拉伸构件的仍然粘稠的材料被模制在带与圆柱形模制轮之间，同时吸收热以形成成品牵引装置并且被硫化，该带在压力下以卷绕角围绕该模制轮卷绕。如上所述，当这种装置用于根据本发明的方法时，必须设计弹性体基质材料的温度控制和供应，使得复合材料不被硫化。然而，在压力下在模制轮上运行的带在此是重要的，并且可用于在织物或纺织品与弹性体材料之间获得可靠的粘接。
有利的发展是弹性体材料是聚合物混合物、特别是橡胶混合物、优选地是无溶剂的聚合物混合物或橡胶制剂/橡胶混合物。为此，可以尤其使用简单生产的不含有任何溶剂的混合物。然后可以省去溶剂，溶剂实际上仅是连接过程所需的，即仅用于降低粘度以允许弹性体材料渗透到织物层的纱线中及其之间。这不仅提高了工作安全性，而且出于环境保护的原因也是极其希望的。
另外的有利的构造是，弹性体材料作为片材被引入带与圆柱形模制轮之间，该片材被引入纺织品或织物层的一侧或两侧。这样的片材可以以任何希望的方式生产为初步材料并且非常容易地整合到生产工艺中。
另外的有利的构造是在带与圆柱形模制轮之间引入多层弹性体材料或纺织品或织物。这使得复合材料的组成和厚度能够以简单的方式适配于生产和/或后续操作的进一步要求。
另外的有利的配置是在带与模制轮之间的模制过程期间，温度不超过150℃、优选地不超过100℃，这特别是对于基质中热敏组分的情况非常重要。“热敏”是用于指在100℃的工艺温度下已经具有超过10％的百分比固化的那些组分的术语。在复合材料的生产期间带与模制轮之间的温度保持低于所述极限的事实意味着可靠地避免在复合材料的生产期间已经出现明显的硫化效果。
根据本发明生产的复合织物材料特别适用于传动带、优选齿形带或其他V形肋式带，这些传动带在其后侧和/或其传动侧覆盖有根据本发明生产的复合织物材料。如以上已经解释的，在这样的传动带(常常在操作上温热的油中或在其他恶劣条件下运行)的情况下，纺织品或织物层以及还有由此覆盖有纺织品或织物层的带被根据本发明的生产方法很好地保护，使得在这种侵蚀性条件下的运行时间和寿命显著增加。
以下纺织品或织物层特别适合用于覆盖传动带，该纺织品或织物层包括在宽度为5cm的纺织品条上测量的在覆盖的纵向方向上在100N的拉伸应力下具有超过50％伸长率的纺织品。即使在更复杂形式的情况下(如例如在齿形带或V形肋式带上存在)，也可以通过覆盖基质束缚的纵向可拉伸纺织品以及因此得到的可伸长的复合材料来很好地生产或覆盖传动带。
