Description

车辆地板区域用包层元件
技术领域
本发明涉及一种包层元件，其由多个层组成，用于车辆的行李舱中的地板区域，其具有面向存储舱的覆盖层、面向车身的声学泡沫层(acoustic foam layer)、和设置在覆盖层和声学泡沫层之间的厚层，其进一步呈现为由发泡的热塑性材料制成的、位于声学泡沫层和厚层之间的载体层。
背景技术
车辆——尤其是小型多用途车辆，例如，敞蓬小型载货卡车或厢式货车——的地板区域，通常由设置在车身镶板上的包层覆盖，其提供声阻尼。因为包层的表面密度应该是低的，泡沫聚合物通常用作听觉上有效的层，例如，基于聚氨酯(PUR)。该泡沫层习惯上被称为声学泡沫层，尤其是在本说明书中。该泡沫层习惯上面向行李舱并被橡胶材料层覆盖，例如，其可由热塑性弹性体构成。一方面，该材料层用于保护下面的泡沫层免于机械和其它环境的影响。另一方面，覆盖层的表面性质保证了滑动阻力和因此的踏面(tread)舒适性。此外，覆盖层具有装饰作用。
声学泡沫层的软质泡沫材料产生充分的声阻尼。然而，软质泡沫材料没有足够的抗压强度以支撑橡胶材料层免于机械的曝光，例如，运输有用载荷。重载荷可在此使该层产生凹痕，在包层的表面留下持久的印迹。这是经济上重大的问题，因为观察者给出了这样的印象，即，包层是质量差的并且相应的车辆已经被大量使用。此外，有凹痕的点造成损伤包层的风险。在行李舱的地板区域上过软的包层也给予装载和卸载的人不舒服和不稳定的感觉，即，限制了脚踏实地的感觉。相比之下，利用较硬泡沫来隔音将限制泡沫的声学有效性。
发明内容
因此，本发明的目标是提供一种车辆——尤其是敞蓬小型载货卡车或厢式货车——中的行李舱的地板区域用包层，其显示出高的声阻尼，以及高的抗压强度。本发明的进一步目标是提供一种方法，通过该方法相应的包层可在时间和成本方面被高效地生产。
第一个目标通过根据本发明的实施例的包层元件实现。第二个目标通过根据本发明的实施例的方法实现。本发明的额外的有利的实施例、方面和细节可从从属权利要求、附图和说明书获得。
根据本发明的用于车辆中的行李舱的地板区域的包层元件，包含面向行李舱的覆盖层、面向车身的声学泡沫层、和设置在覆盖层和声学泡沫层之间的厚层，其中，覆盖层呈现为基于烯烃的热塑性弹性体，其中，厚层呈现为包含无机物的热塑性弹性体，并且其中，包层元件进一步呈现为设置在声学泡沫层和厚层之间的由发泡的热塑性弹性体构成的载体层。该载体层可——特别地——由发泡的聚丙烯构成。
根据本发明的包层元件相比于传统的包层的优点是，在重载荷的运输和合成压力施加到表面上之后，没有可见的痕迹留在表面上。观察者相应地对质量方面留下了好印象。进一步地，根据本发明的包层元件是有利的，因为更耐压的表面不受到同样多的损伤的风险，这给予其更长的使用寿命。此外，车辆的地板上的人不会明显地陷入到包层中，这给予他们/她们更大的脚踏实地的感觉，从而使他们/她们感觉更安全和更舒服。
考虑到高的抗压溃性能，根据本发明的包层元件可承受高载荷而没有载荷在包层元件中留下痕迹。因此，载体层显示出抗压溃性能，其相对于根据本发明的整个包层元件施加至少42N/cm2的抗压溃性能，优选50N/cm2，更优选60N/cm2，并且特别优选70N/cm2。
进一步地，载体层可具有300-500kg/m3的体积密度，优选350-450kg/m3。
声学泡沫层可呈现为聚氨酯泡沫体。
根据本发明的包层元件优选基本上平的。这是有利的，因为车辆行李舱的地板区域作为用于待运输物体的支撑面在很大程度上是平的，即，仅显示出轻微的三维变形，并且地板区域的根据本发明的包层应该是适合于后者。
厚层具有1500至2000kg/m3的体积密度，优选1650至1950kg/m3，并且更优选1750至1900kg/m3。
声学泡沫层可具有30-70kg/m3的体积密度，优选40-60kg/m3的体积密度，并且更优选50kg/m3的体积密度。
本发明进一步涉及一种制造用于车辆的行李舱的地板的根据本发明的包层元件的方法。根据本发明的方法包含以下步骤：
-提供由发泡的热塑性弹性体构成的载体层；
-切割载体层以匹配车辆的行李舱地板的轮廓；
-提供厚层，其呈现为包含无机物的热塑性弹性体；
-将载体层定位在厚层上；
-将声学泡沫层的聚合物泡沫体施加至载体层。
作为替换物，可提供由覆盖层和厚层构成的复合材料代替厚层。
声学泡沫层可以在注塑过程中施加在注塑成型工具中，其中，包含载体层和厚层的复合材料被预先嵌入到注塑成型工具中。
在本发明的进一步发展中，包含将包层元件和覆盖层一起定位在顶部并将其切割以匹配最终的形状的附加步骤。
根据本发明的将要覆盖行李舱地板区域的车辆可在此是适用于运输有用载荷所需的任何车辆。在此优选机动车辆，包括敞蓬小型载货卡车，包括特别优选的厢式货车，当术语“厢式货车”用在本说明书中时指的是微型客车的尺寸的机动车辆，其具有用于运输物体的行李舱。
“面向存储舱”表示面向行李舱的体积、或者直接远离车身部件——尤其远离存储舱的地板区域——并进到车辆内部中的包层元件的侧面或它的层中的一个。
“面向车身”表示面向车身部件——尤其是行李舱的地板区域的包层元件的侧面或它的层中的一个。
附图说明
本发明将根据图1被更详细地描述。附图中：
图1是描述了用于车辆的地板区域的包层的结构设计的示意图。
具体实施方式
在该实施例中，覆盖层2呈现为基于烯烃的热塑性弹性体(TPO)。覆盖层2可完全由一种TPO构成，或者由各种TPO的混合物构成。然而，覆盖层2也有可能由混合了其它聚合物的TPO构成，例如，结合了天然橡胶的TPO。然而，其它的热塑性弹性体也可存在于覆盖层2中。
覆盖层2具有0.5至1.0mm的优选的层厚度，更优选0.6至0.9mm，更加优选0.6至0.8mm，并且特别优选0.7mm。平均层厚度可变化达到10％。
位于覆盖层2和声学泡沫层4之间的厚层3是有利的，一方面因为其保护下面的层免于机械和其它环境的影响。另一方面，厚层3机械地支撑覆盖层2，因为否则当后者接触到载荷时会被轻易地压到声学泡沫层4中并被损坏。因此，厚层3为根据本发明的包层元件的表面提供机械稳定性。厚层3呈现为包含无机物的热塑性弹性体。包含无机物表示该层包含无机填料。厚层3可在此完全由包含无机物的热塑性弹性体构成，例如，TPO，或由不同的热塑性弹性体的混合物构成，或甚至由具有额外的聚合物——例如，具有天然橡胶——的一个或多个热塑性弹性体的混合物构成。所添加的无机物保证了在制造过程中良好的流动特性、材料的经济性、以及因此的——尤其当其用在针对车辆行李舱的地板区域的包层元件中时——稳定性、阻力、高密度、刚性并因此还抵抗变形。添加至聚合物中的典型的无机物可以是碳酸钙、氧化钛、氧化硅、石英、氧化锌、砂、硅藻土、高岭土、白垩、玻璃纤维、滑石、钙硅石。
厚层3具有1.0至3.0mm的优选的层厚度，更优选1.5至2.5mm的层厚度，更加优选1.7至2.0mm的层厚度，以及特别优选1.8mm的层厚度。虽然厚层3可具有1500至2000kg/m3的体积密度，但其优选具有1650至1950kg/m3的体积密度，更加优选1750至1900kg/m3的体积密度。在该实施例中，厚层3具有1850kg/m3的体积密度。
声学泡沫层4可呈现为由适合于该目的的聚合物材料构成的任何泡沫体。在该实施例中，声学泡沫层4呈现为聚氨酯(PUR)。在这种情况下，优选声学泡沫层4完全由PUR构成。因为轻泡沫材料比重泡沫材料对于声学隔音更有效，因此声学泡沫层4由轻泡沫材料构成是有道理的。虽然，声学泡沫层4可具有30-70kg/m3的体积密度，但其优选具有40-60kg/m3的体积密度。在该实施例中，声学泡沫层具有50kg/m3的体积密度。声学泡沫层4的厚度优选地测量5-30mm，更优选5-25mm，更加优选5-20mm，并且特别优选5-16mm。
包含发泡的热塑性弹性体并位于厚层3和声学泡沫层4之间的根据本发明的载体层5是有利的，因为比传统的包层给予包层元件1高的抗压溃性能。根据本发明，载体层5在此特别优选由发泡的聚丙烯(PP)构成。也可使用由其它的发泡的热塑性弹性体——例如，聚乙烯——制成的。也有可能使用适当的发泡的聚合物的混合物。
载体层5具有1至10mm的优选层厚度，优选1.5至8mm的优选层厚度，更优选2至6mm的优选层厚度，更加优选2.5至4mm的优选层厚度，并且特别优选3mm的优选层厚度。虽然，载体层5可具有300-500kg/m3的体积密度，但优选地，载体层5可具有350-450kg/m3的体积密度，特别地，400kg/m3的体积密度。
特别地，与传统的包层相比，载体层5增加了根据本发明的包层元件的抗压溃性能。抗压溃性能也称作压痕硬度，抗压溃性能是力，通过该力，主体对抗垂直作用的载荷的压痕。换言之，抗压溃性能是以一定百分比使主体产生凹痕所需的力，在此特别是由泡沫材料制成的主体。在该实施例中，载体层显示出抗压溃性能，其相对于根据本发明的整个包层元件施加至少42N/cm2的抗压溃性能，优选50N/cm2的抗压溃性能，更优选60N/cm2的抗压溃性能，特别优选70N/cm2的抗压溃性能。
本实施例的包层元件基本上是平的。这是有利的，因为车辆行李舱的地板区域作为用于待运输物体的支撑面在很大程度上是平的，即，仅显示出轻微的三维变形，并且地板区域的根据本发明的包层应该是适合于后者。行李舱表面上的较小的不平整可通过声学泡沫层4的弹性抵消。由车辆的技术导致的较大的不平整——例如，关于针对车辆车轮或线路或控制的槽的凹处——可在制造根据本发明的包层元件1时被考虑到并通过相应地模制包层元件1被调整为车辆地板的形状。此外，凹处部分可存在于由覆盖层2和厚层3构成的材料层中。这些是有利的因为它们允许通过将螺纹套管接头连接至装载地板表面以固定包层元件，而无需突出于包层元件的表面的螺钉头。
在优选的实施例中，包层元件1完全覆盖车辆地板区域。这是有利的，因为行李舱的地板区域完全以具有经济意义的方式使用。在这不是所期望的特殊实施例中，然而，仅地板区域的一部分可由根据本发明的包层元件1覆盖。
一种制造包层元件1的方法，包含以下步骤：
-提供由发泡的热塑性弹性体制成的载体层；
-切割载体层以匹配车辆的行李舱地板的轮廓；
-提供厚层，其呈现为包含无机物的热塑性弹性体；
-将载体层定位在厚层上；
-将声学泡沫层的聚合物泡沫体施加至载体层。
发泡的热塑性弹性体可被，例如，通过适合于该目的的工具手工切割成材料毛坯以匹配将要覆盖的地板区域的轮廓。该实施例是有利的，因为以这种方式制造不需要主要设备支出，并且也可由较小的转包商或商店处理。此外，这允许为不同车辆类型的行李舱快速地提供包层元件。然而，也有可能采用自动化机械将层切割成不同尺寸。
在有利的实施例中提供的厚层的替代物是由厚层和设置在其上的覆盖层组成的复合材料。然而，也有可能在该过程以后的过程中，覆盖层被放置在厚层上。
通常的方法用于连接载体层和厚层。一个可能的示例包含通过热量供给进行热塑性连接。也有可能是胶接。另一选择包括机械粘合，例如，通过螺纹套管接头。
在注塑过程中，声学泡沫层可施加于载体层。声学泡沫层呈现为PUR或完全由PUR构成是有利的。PUR的使用是有利的，因为其特别适合于在注塑过程中直接施加。优选包含厚层和载体层的复合材料，其在注塑过程之前被嵌入注塑成型工具中。声学泡沫层在之后施加于注塑过程中。当施加声学泡沫层时，凹处可被引入泡沫层中以匹配将要覆盖的行李舱地板的形状。
然而，还有其它可能的方式施加声学泡沫层，例如，通过预先将其从一种材料中切割出来并在之后将其定位在载体层上。
至少在这点上，覆盖层设置在厚层上，除非已经准备好由厚层和覆盖层构成的复合材料。
在优选的实施例中，根据本发明的用于制造包层部件的方法包含另一步骤：
-将包层元件和覆盖层一起定位在顶部并将其切割以匹配最终的形状。
载体层在此作为样板，并且由厚层和覆盖层构成的复合材料连同声学泡沫层的各自突出的边缘区域被裁剪以匹配载体层的轮廓。此外，在该步骤中，孔可被切割成包层元件，通过这一步骤，包层元件可固定至行李舱的地板区域，例如，通过螺纹套管接头。有利的是并且因此优选的是，水射流切割机可用于按尺寸切割，因为没有大量的热被引入到材料中。
本发明的权利要求的保护范围所包含的本发明的改进和变化对于本领域技术人员来说是显而易见的。
