Description

结构强度高的车辆内装饰板
技术领域
本发明涉及一种结构强度高的车辆内装饰板，具体说涉及一种用于汽车底盘上层、具有隔音、隔热、减震要求的结构强度高的车辆内装饰板。
背景技术
目前市场上的针刺类的车辆内装饰板，是以聚酯类化纤短丝为原料，通过开松、混合、梳理、铺网工序形成均匀的纤网，采用针刺固结、毛刷针刺，形成针刺无纺面料以其作为表层，经过热定型、定型胶涂层工艺处理，将其与PE复合，再加热模压成形后，在底层高压注入PU发泡材料，模合而成。这种多层复合而成的内饰材料由于PE材料的隔音效果较差，难以保证中、高档汽车对隔音效果的要求，通常有水洒落在车辆内饰板上之后只有简单的擦拭，等待自然干燥，容易发霉，易脏，车辆在潮湿环境下长期停放也会造成内饰板发霉。
发明内容
本发明的目的是提供一种结构强度高的车辆内装饰板，该内饰件易粘合，且隔音、隔热、减震效果好。
本发明的结构强度高的车辆内装饰板，其表层为聚脂类化纤针刺无纺面料，底层为PU发泡层，所述表层的内侧设有背胶层，背胶层与底层之间设有EPDM粘结层，EPDM粘结层与底层之间设有一层聚酯类针刺无纺布，所述表层、背胶层、EPDM粘结层与聚酯类针刺无纺布通过压合固定相连；所述表层与背胶层之间还设有防潮层；所述防潮层包括环氧树脂板和固化于环氧树脂板内部的电热部件；还设有孔套；所述孔套贯穿于表层、背胶层、EPDM粘结层、聚酯类针刺无纺布、底层和防潮层；所述孔套的外壁对应表层、背胶层、EPDM粘结层、聚酯类针刺无纺布、底层和防潮层之间的贴合面分别设有凸缘；所述凸缘夹紧固定于相应贴合面内。
进一步，所述的底层PU发泡层采用的是软质PU。
进一步，所述电热部件为电热丝网。
进一步，所述凸缘的厚度沿径向自内到外逐渐变小。
由上述技术方案可知，本发明通过在无纺面料的表层及底层PU发泡层之间设有EPDM粘结层，EPDM粘结层的隔音、隔热、减震效果好，同时在EPDM粘结层与底层PU发泡层之间设有一层聚酯类针刺无纺布，由于聚酯类针刺无纺布与EPDM粘结层及底层PU发泡层中所用材料的极性相反，所以易与粘合，同时粘结强度高，提高了制成率，降低了生产成本；内饰板弄湿或受潮后可利用防潮层的热量进行快速烘干，利于保持干净整洁，防止发霉，孔套的内孔形成让位孔结构，利于排线，孔套安装结构稳定，不易损坏，使用寿命久。
附图说明
图1是本发明的结构示意图。
具体实施方式
如图1所示的一种结构强度高的车辆内装饰板，其表层1为聚脂类化纤针刺无纺面料，底层2为PU发泡层，所述表层1的内侧设有背胶层3，背胶层3与底层2之间设有EPDM粘结层4，EPDM粘结层4与底层2之间设有一层聚酯类针刺无纺布5，所述表层1、背胶层3、EPDM粘结层4与聚酯类针刺无纺布5通过压合固定相连；所述表层1与背胶层3之间还设有防潮层；所述防潮层包括环氧树脂板6和固化于环氧树脂板6内部的电热部件7；还设有孔套8；所述孔套8贯穿于表层1、背胶层3、EPDM粘结层4、聚酯类针刺无纺布5、底层2和防潮层；所述孔套8的外壁对应表层1、背胶层3、EPDM粘结层4、聚酯类针刺无纺布5、底层2和防潮层之间的贴合面分别设有凸缘9；所述凸缘9夹紧固定于相应贴合面内；所述的底层2PU发泡层采用的是软质PU；所述电热部件7为电热丝网；所述凸缘9的厚度沿径向自内到外逐渐变小。作为本发明的优选方案，在表层1的下面设有一层背胶层3，作用在于可以对面料起定形作用。作为本发明的优选方案，底层2PU发泡层采用的是软质PU，由于软质PU的隔音隔热效果都强于硬质PU，所以使整个内饰件的隔音效果增强；内饰板弄湿或受潮后可利用防潮层的热量进行快速烘干，利于保持干净整洁，防止发霉，孔套8的内孔形成让位孔结构，利于排线，孔套8安装结构稳定，不易损坏，使用寿命久。
首先将聚脂类化纤针刺无纺面料的表层1经过热定型和定型胶定型，再将其与聚酯类针刺无纺布5用EPDM复合形成粘结层4，粘贴好防潮层，经过热模压成形后，通过模具高压注入PU泡沫材料，形成汽车厂家所需的内饰件。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
