Abstract

用于机动车辆的多层塑料管包括第一层管和位于第一层管周围的第二层管。第一层比第二层硬并且比第二层薄。

Description

耐高温的多层管
引言
本发明涉及多层管。更具体地，本发明涉及耐高温的多层管。
多种类型的软管应用于机动车辆中。对于一些应用，例如在变速箱油冷却器和发动机油冷却器应用中，软管必须承受高温和高压。在其他应用中，软管必须抵抗当暴露于例如燃料等化学品时引起的降解。无论何种应用，软管通常都很重，并且不像热塑性管那样顺服于用于发动机罩下包装的拉紧弯曲半径。
因此，尽管当前机动车辆的软管实现了其预期目的，但是需要一种新型改进的管道，用于在各种机动车辆应用中传输气体和液体。

根据本发明的另一方面，多层塑料管包括粘合剂层，以将导电材料层粘合到第一层管。
根据本文所提供的描述，其他应用领域将变得显而易见。应当理解，说明书和具体实施例仅用于说明的目的，而不用于限制本发明的范围。
附图说明
本文描述的附图仅仅是为了说明的目的，并不旨在以任何方式限制本发明的范围。
图1是根据本发明原理的多层管的截面图；以及
图2是图1所示的具有附加导电材料层的多层管的截面图。
具体实施方式
以下描述本质上仅仅是示例性的，并不旨在限制本发明、应用或使用。
参照图1，示出了用于机动车辆应用的多层塑料管10。多层塑料管10包括厚度为t2的第一层管14，其位于厚度为t1的第二层管12内。可选地，厚度为t3的粘合剂层16能够用于将第一层管14和第二层管12粘合在一起。第一层管14比第二层管12硬。
在特定应用中，第一层管14和第二层管12的厚度在大约0.25mm和5mm之间，第一层管14的厚度t2小于第二层管12的厚度t1。第一层管14能够由聚苯硫醚(PPS)制成，第二层管12能够由聚邻苯二甲酰胺(PPA)制成。第一层管14的厚度确保多层塑料管10的柔性，同时第一层管的刚度在加压或高温真空条件下保持对多层塑料管10的支撑。多层塑料管10经配置用于大约180℃的最大连续操作温度。
通常，粘合剂层16的厚度t3分别薄于第一层管14和第二层管12的厚度t1和t2。在一些应用中，粘合剂层16由例如具有官能团的改性聚烯烃制成，或者能够由任何其他合适的材料制成。多层塑料管10适用于经受大约例如550kPa的高压和大约例如180℃的高温的机动车辆应用，例如变速箱油冷却器(TOC)应用或发动机油冷却器应用(EOC)。在其他应用中，例如在传输蒸汽气体时，能够经历大约200kPa的压力，与TOC或EOC应用相比，第一层管14和第二层管12的厚度更薄。
在比经受例如100kPa至275kPa压力的TOC或EOC应用要求更低的其他低压应用中，第二层管12能够由聚酰胺612(PA612)而不是PPA制成。PA612在高温下也不如PPA坚固。然而，PA612比PPA便宜。PA612的厚度介于大约0.25mm至5mm之间。PA612层12通常比PPS层14厚。同样，能够使用可选的粘合剂层16将PA612层12和PPS层14粘合在一起。
在多层塑料管10的某些应用中，例如，当管10用于液体燃料的传输时，导电材料层18(如图2所示)能够位于第一层管14的内部上。可选的粘合剂层能够用于将导电材料层18粘合到第一层管14。导电材料层18能够由聚四氟乙烯(PTFE)制成并且能够具有大约0.1mm的厚度。应当注意，这种导电层对于燃料蒸汽的传输不是必需的。
在任何上述应用中，第一层管14和第二层管12能够切割成一定长度，然后在成形夹具中再加热，使得多层塑料管10具有特定的构造。为了将多层塑料管10连接到所需系统，多层塑料管10的ID能够强制压在与系统连接的塑料接头的OD中模制的倒钩上。或者，多层塑料管10能够旋转焊接到塑料接头上。更具体地，将多层塑料管10的ID放置在塑料接头的OD上，并且强制压在该塑料接头上，直到多层塑料管10的端部与连接器主体邻接。然后快速旋转连接器，直到摩擦力熔化塑料表面。塑料的冷却在连接器和多层塑料管10的端部之间产生粘合。如果连接器由金属制成，则通常将管10强制压过连接器的金属杆上的镦粗部。如果在多层塑料管10的端部上使用快速连接器，则连接器的端口端(即，凹端)卡扣到具有设计成锁定到端口端的端部镦粗部的塑料或金属管上。
本发明的描述本质上仅仅是示例性的，并且不脱离本发明的要旨的变化旨在落入本发明的范围内。这些变化不应视为脱离本发明的精神和范围。
