Description

制备弹性汽车内层材料或结构板的方法及此方法制备的产品
技术领域
本发明涉及弹性汽车内层材料或结构板的制备方法。方法具体包括：1.将聚丙烯纤维和聚乙烯纤维混合在一起的短纤维梳理在泡沫层的一侧或两侧，该泡沫层是通过发泡从一组聚丙烯片(polypropylene chips)、聚乙烯片(polyethylene chips)、聚氨酯片(polyurethane chips)和发泡聚苯乙烯片(expanded polystyrene chips)中选择出来的任意一种物质制备的；2.通过针刺工序交织短纤维，使得短纤维以束的形式定形在泡沫层里。
背景技术
依据当前把汽车视为必需品的趋势，改进汽车内部、安全和驾驶舒适的需求逐渐增加。为了满足这样的需求，各种各样的内层材料或内层板应用于车头衬垫，车门装潢，汽车后架，行李箱垫，汽车垫，地板材料，引擎罩垫，车顶材料，结构内层材料和隔音材料。
最近，内层材料使用的板是从纸、聚乙烯、织物、非织物纤维、毛毡和此类复合物中选择出来的一种物质制造的。目前，内层材料的功用为装饰汽车内部使用户在车内感觉舒适，保持车内温暖或使车内防热，隔绝或吸收外部声音从而防止外部声音进入车内，以及减少冲击力。
因此，内层材料除了外表美观还必须具有良好的热隔绝性，隔音和吸音性，以及减震性。此外，内层材料其重量必须轻，以减少汽车的重量，必须具有良好的可加工性，以应用于复杂的汽车内部结构，并且按照汽车种类的改变来处理结构的改变。
传统汽车内层材料的一个例子包括两个不同的层。详细的说，两个不同层中的一层是聚乙烯纸和隔离纸附着在毛毡的两侧；另外一层是海绵和织物附着在纸板的一侧。
在这一点上，毛毡吸收并隔绝外部声音，隔离纸保护着接触车顶的毛毡的一侧，聚乙烯纸防止毛毡底侧的表面缺陷或毛毡底侧的污染。此外，纸板可以防止毛毡弯曲，并且织物附着在功用为表面垫的海绵上，作为呈现良好外观的最终材料。
然而，传统汽车内层材料的不足在于一个板的制造是通过使用各种各样的材料，如隔离纸、毛毡、聚乙烯纸、纸板、海绵和织物，其生产过程长，并且生产成本增高。传统汽车内层材料的另外一个不足在于组成汽车内层材料的大部分材料不能回收，因此导致环境污染。
同时，提出用一个板(地毯)来改善隔音和隔绝效果，其功能性纱插入到硬性非织物纤维，然后将软性非织物纤维层压到结果结构上。然而，这种板可加工性较差，因此不能作为汽车内层材料使用。同样，研发改进的板是将聚乙烯树脂涂层在板的任一侧，但这样做的不足在于板的表面受到污染或者功能性纱凝结成团，这是由于加工过程中聚乙烯树脂的加热和压缩导致聚乙烯树脂缓慢的从板里渗出而造成的。
因此，有必要研发一种可回收的、可加工性、声音隔绝性、隔音性、热隔绝性和减震性均得到改进的轻型汽车内层材料。再者，消费者希望得到既减少颤动和冲击力又对健康无害而且外表美观的轻型汽车内层材料。
发明内容
因而，考虑到现有技术存在的问题，本发明的目的在于提供一种具有良好可加工性的汽车内层材料或结构板的制备方法。
本发明的另一个目的在于提供由本发明方法生产的具有良好可加工性的汽车内层材料或结构板，进而提供使用此方法生产的汽车罩板或结构罩板。
本发明的进一步目的在于提供一种生产汽车内层材料或结构板的方法，其短纤维层和纤维层通过加热完全附着到泡沫层，因而形成板状结构。在这点上，该汽车内层材料或结构板应用于汽车后架，车门装潢，车头衬垫，行李箱垫，地板材料，车顶材料和引擎罩垫，它不容易弯曲，但具有良好的可加工性、热隔绝性、隔音吸音性，因此可应用于床垫或结构材料。
附图说明
下面结合附图对本发明的上述及其他方面特征和优点作详细说明，以便更清楚的理解本发明。
图1是本发明具有良好可加工性的汽车内层材料或结构板的剖面图。
3为泡沫层；4a、4b为短纤维层；5a、5b为纤维层；6为短纤维。
具体实施方式
为了实现本发明的上述目的，最佳的第一个方法实施例包括以下步骤：1)以3～7∶7～3的混合比率将聚丙烯纤维和聚乙烯纤维混合在一起的短纤维梳理在一泡沫层的一侧或两侧，该泡沫层是通过发泡从一组聚丙烯片、聚乙烯片、聚氨酯片和发泡聚苯乙烯片中选择出来的任意一种物质制备的；2)通过针刺工序交织短纤维使其以束的形式定形在泡沫层上；3)通过把暴露在泡沫层外部的短纤维部分加热至120摄氏度到250摄氏度并且熨烫(或压制)进而熔化，冷却并硬化短纤维的熔化部分，形成一短纤维层(或多层)。
此外，最佳的第二个方法实施例包括以下步骤：1)以3～7∶7～3的混合比率将聚丙烯纤维和聚乙烯纤维混合在一起的短纤维梳理在一泡沫层的一侧或两侧，该泡沫层是通过发泡从一组聚丙烯片、聚乙烯片、聚氨酯片和发泡聚苯乙烯片中选择出来的任一种物质制备的；2)通过针刺工序交织短纤维使其以束的形式定形在泡沫层上；3)将纤维层置于泡沫层上，以3～7∶7～3的混合比率将聚丙烯纤维或聚乙烯纤维与天然纤维混合在一起的纤维第二次梳理在泡沫层外部的两侧；4)通过把暴露在泡沫层外部的短纤维层(多层)部分加热至120摄氏度到250摄氏度，并且熨烫(或压制)进而熔化，冷却并硬化纤维层的熔化部分，形成纤维层(多层)同时形成短纤维层(一层或多层)。
为此，硬性板状汽车内层材料或结构板通过该第二个方法实施例生产出来了。
为了实现本发明的以上目的，最佳的第三个方法实施例包括以下步骤：1)将聚丙烯纤维和聚乙烯纤维混合在一起的短纤维梳理在一泡沫层的一侧或两侧，该泡沫层是通过发泡从一组聚丙烯片、聚乙烯片、聚氨酯片和发泡聚苯乙烯片中选择出来的任一种物质制备的；2)形成短纤维层，通过把泡沫层一侧或两侧的短纤维部分加热至120摄氏度到250摄氏度，并且熨烫(或压制)进而熔化，冷却并硬化从泡沫层突出的短纤维层熔化部分(泡沫层突出的部分是在熨烫短纤维部分进而熔化短纤维部分时突出出来的)形成短纤维层(一层或多层)。
此外，本发明目的的实现通过以下第四个方法实施例的步骤：1)将聚丙烯或聚乙烯纤维和天然纤维混合在一起的短纤维梳理在一个泡沫层的一侧或两侧，该泡沫层是通过发泡从一组聚丙烯片、聚乙烯片、聚氨酯片和发泡聚苯乙烯片中选择出的任一种物质制备的；2)通过针刺工序交织短纤维使其以束的形式定形于泡沫层里；3)通过把泡沫层外部的短纤维部分加热至120摄氏度到250摄氏度，并且熨烫(或压制)进而熔化，冷却并硬化短纤维的熔化部分，形成短纤维层(一层或多层)。
在这方面，短纤维最好包括以3～7∶7～3的混合比率混合在一起的非易燃或普通聚丙烯纤维和聚乙烯纤维。
同样，最好采用在重量上包括20％到40％的低熔点聚乙烯成分的聚乙烯纤维。
再者，纤维层最好是按3～7∶7～3的混合比率含聚丙烯纤维或聚乙烯纤维与天然纤维混合的成分。在这一点上，天然纤维是从亚麻(linen)、黄麻(jute)、莎草(great water rush)、蕉麻(abaca)、椰壳(Coconut)、波罗麻(sisal)、箭木(arrowroot)一组植物纤维材料中选出的一种制备的。
同时，通过本发明方法生产出来具有良好可加工性的汽车内层材料或结构板。
此外，本发明提供了一种汽车罩板或结构罩板(automobile orconstruction Panel)，通过将非易燃或普通纤维热熔或附着到按照本发明方法生产的汽车内层材料或结构板的一侧或两侧。
汽车罩板或结构罩板的生产也可通过将从熟石膏(plasters)、水泥(cements)和陶瓷涂料(ceramic pigments)选择出来的任何一种材料按照预先确定的厚度涂覆在汽车内层材料或结构板的两侧，使用热空气烘干，然后热压。
参见图1，为按照本发明第二个最佳方法实施例生产的具有良好可加工性的汽车内层材料或结构板。该汽车内层材料或结构板包括一个泡沫层3，该泡沫层是通过发泡从一组聚丙烯片、聚乙烯片、聚氨酯片和发泡聚苯乙烯片中选择出的任一种物质制备的；短纤维层4a，4b，层压在泡沫层3的两侧；以及纤维层5a，5b，成层在短纤维层4a，4b上。这时，每一纤维层5a或5b含聚丙烯纤维或聚乙烯纤维与天然纤维混合在一起的成分。
根据本发明，短纤维层4a，4b可以使用按照预先确定混合比率混合的聚丙烯纤维和聚乙烯纤维。聚乙烯纤维重量上最好包括20％到40％、在70摄氏度到150摄氏度熔化的低熔点聚乙烯成分。因此当汽车内部材料或结构板加热到120至250摄氏度并且压制时，按照梳理工序层压在泡沫层3两侧的短纤维层4a，4b或按照针刺工序镶嵌在泡沫层3里的短纤维6的每层合成物，都采用聚乙烯纤维，最好采用低熔点的聚乙烯纤维，来同时熔化并形成硬化的板状结构。这里，低熔点纤维是指熔点比普通纤维低10到30摄氏度的纤维。
尤其是，从亚麻、黄麻、great water rush、蕉麻、椰壳、波罗麻和箭木中选出的一种植物纤维材料制备的天然纤维同聚丙烯纤维混合在一起，形成板状纤维层5a，5b。
具体地说，聚丙烯纤维以3～7∶7～3的混合比率同天然纤维混合在一起形成纤维层5a，5b，聚丙烯纤维以3～7∶7～3的混合比率同聚乙烯纤维混合在一起形成短纤维层4a，4b。尤其是，聚乙烯纤维重量上最好包括20％到40％、在70到150摄氏度熔化的低熔点聚乙烯成分。
因此，根据本发明方法，硬化板状汽车内层材料或结构板可以获得如下两种类型：一是先按照梳理工序使用梳理设备在泡沫层3上形成短纤维层(多层)，然后按照针刺工序将短纤维彼此交织，使其以束的形式镶嵌在泡沫层3里，最后通过加热到120至250摄氏度并且压制，形成短纤维。
或者，先按照梳理工序使用梳理设备在泡沫层3上形成短纤维层4a，4b，然后按照针刺工序将短纤维彼此交织，使其以束的形式镶嵌在泡沫层3里，继而按照预先确定的混合比率，把聚丙烯纤维同从亚麻、黄麻、greatwater rush、蕉麻、椰壳、波罗麻和箭木中选出的天然纤维混合在一起制备的纤维层5a，5b成层在短纤维层4a，4b上，然后加热结果结构至120至250摄氏度并压制。镶嵌在泡沫层3里的聚乙烯纤维(低熔点聚乙烯纤维)被熔化，然后冷却，导致纤维层5a，5b附着到短纤维层4a，4b的两侧。包括泡沫层3、短纤维层4a，4b和纤维层5a，5b的板状结构的形成是由于每层熔化的聚乙烯冷却的结果。
通过阅读以下例子可以更好的理解本发明，这些例子意在阐述，但并非限定发明。
实施例1
具有一泡沫层和短纤维层(多层)的汽车内层材料或结构板按照如下程序制备：使用传统梳理设备，将短纤维经过梳理工序梳理到一泡沫层一侧或两侧。这时，短纤维包括聚丙烯纤维和重量上含30％低熔点聚乙烯成分的聚乙烯纤维，以5∶5的混合比率混合在一起。在这里，该泡沫层是通过发泡从一组聚丙烯片、聚乙烯片、聚氨酯片和发泡聚苯乙烯片中选择出的任一种物质生产出来的。
按照预先确定的厚度置于泡沫层上的短纤维通过针刺工序彼此交织，使短纤维以束的形式镶嵌在泡沫层里。不管短纤维使用梳理工序置于泡沫层的一侧还是两侧，短纤维均可采用一侧针刺工序或两侧针刺工序。
泡沫层外部的短纤维部分被加热到190摄氏度，并且被熨烫至熔化然后硬化，在泡沫层上形成短纤维层(多层)，从而生产出具有良好可加工性的硬性板状汽车内层材料或结构板。
实施例2
具有一泡沫层、短纤维层(多层)和纤维层(多层)的汽车内层材料或结构板按照如下程序制备：使用传统梳理设备，将短纤维经过梳理工序梳理到泡沫层一侧或两侧。这时，短纤维包括聚丙烯纤维和重量上含30％低熔点聚乙烯成分的聚乙烯纤维，以5∶5的混合比率混合在一起。在这里，泡沫层是通过发泡从一组聚丙烯片、聚乙烯片、聚氨酯片和发泡聚苯乙烯片中选择出的任一种物质生产出来的。
按照预先确定的厚度置于泡沫层上的短纤维通过针刺工序彼此交织，使短纤维以束的形式镶嵌在泡沫层里。不管短纤维是使用梳理工序置于泡沫层的一侧还是两侧，短纤维均可采用一侧针刺工序或两侧针刺工序。此后，以5∶5混合比率将聚丙烯纤维或聚乙烯纤维和天然纤维混合在一起，暴露在泡沫层外的短纤维部分经历梳理工序，在泡沫层的两侧形成纤维层(多层)。在这里，其天然纤维选自亚麻、黄麻、great water rush，蕉麻、椰壳、波罗麻和箭木。
此外，纤维层(多层)被加热到210摄氏度，并且压制，以熔化暴露在泡沫层一侧或两侧的短纤维部分，然后使其硬化并形成短纤维层(多层)，并同时附着在泡沫层和纤维层(多层)之间，进而生产出具有良好可加工性的硬性板状汽车内层材料或结构板。
在这里，因为应用到纤维层(多层)的热度被确定为高出实施例1中短纤维热度10至20摄氏度，尽管短纤维没有被直接加热，热量还是通过纤维层转移到短纤维，由此短纤维可被充分的熔化。
根据本发明，非易燃或普通纤维材料被进一步附着到实施例1、实施例2生产出来的汽车内层材料或结构板的一侧或两侧，进而生产出汽车罩板或结构罩板。
此外，汽车罩板或结构罩板的制备是从熟石膏、水泥和陶瓷涂料选择出来的任何一种材料按照预先确定的厚度涂覆在实施例1、实施例2生产出来的汽车内层材料或结构板的两侧，使用热空气烘干，然后热压。
工业适用性：
从上述描述中可以清楚的看到，本发明的优点是：在生产具有良好可加工性、硬性高弹性汽车内层材料或结构板方面，不存在易弯曲、低强度的不足。原因在于包括聚丙烯纤维和聚乙烯纤维混合在一起的短纤维经历梳理工序梳理在泡沫层的一侧或两侧，该泡沫层是通过发泡从一组聚丙烯片、聚乙烯片、聚氨酯片和发泡聚苯乙烯片选择出的任一种物质制备的，然后通过针刺工序彼此交织短纤维在泡沫层里，镶嵌短纤维在泡沫层里。
本发明的其他优点在于短纤维层和纤维层通过加热方式全部附着到泡沫层，以形成板状结构，本发明制备的汽车内层材料或结构板可应用于汽车后架，车门装潢，车头衬垫，行李箱垫，地板材料，车顶材料和引擎罩垫。它不容易弯曲，但具有良好的可加工性、热隔绝性、隔音吸音性，因此被应用于床垫或结构材料。
此外，泡沫和短纤维由相同材料制成，泡沫和短纤维材料的实例包括聚丙烯、聚乙烯和聚氨酯。这样，当短纤维热熔在泡沫上时，实现泡沫和短纤维之间的全面粘附。
同样，在本发明中，短纤维层成层在泡沫层的一侧或两侧，或者短纤维层(多层)和纤维层(多层)相继成层在泡沫层的一侧或两侧。此后，非易燃或普通纤维进一步附着到上述结构的两侧，或者从熟石膏、水泥和陶瓷涂料选择出来的任何一种材料按照预先确定的厚度涂覆在上述结构的两侧，进而生产出汽车罩板或结构罩板。
上列为例举实施例的方式对本发明之具体说明，该实施例的使用意在描述并非用以限制本发明的专利范围，根据上述方法，本发明可进行许多修改和变化。因此应该理解，在权利要求范围内本发明还可以有等效实施或变更。
