Abstract

本实用新型涉及一种汽车隔音密封件，具有密封层，所述密封层上设有隔音层，密封层与隔音层之间设有粘接层。本实用新型在发泡密封件片材表面，用胶粘剂把聚氨酯薄膜与发泡密封件片材粘帖牢固，这样汽车传入发泡密封件片材的噪声的声波能量大部分被聚氨酯薄膜反射回发泡密封件，使得噪声驻留消耗在发泡密封件上，噪声在多孔间隙的发泡密封件里转变成了热能，从而实现降噪隔音减震密封的更好效果。

Description

汽车隔音密封件
技术领域
本实用新型涉及一种汽车密封部件，特别涉及一种汽车隔音密封件。
背景技术
随着汽车工业的发展，人们对轿车的乘坐舒适性以及防振、隔噪性能要求越来越高。汽车噪音(如发动机噪音、轮胎噪音)一股通过车身钣金和框架的振动传递到驾驶室里，并且这些噪音在传递过程中会带动金属板振动，产生二次噪音，为了降低噪声，汽车里大量使用聚氨酯发泡材料用来制作密封件，因聚氨酯密封件是多微孔结构，噪声波在其中难以驻留消耗成热量，因此隔音效果不明显。
实用新型内容
本实用新型的目的是提供一种克服上述缺点，隔音效果较好的汽车隔音密封件。
实现本实用新型目的的技术方案是：一种汽车隔音密封件，具有密封层1，所述密封层1上设有隔音层3，密封层1与隔音层3之间设有粘接层2。
上述汽车隔音密封件的隔音层3为聚氨酯薄膜，通过粘接层2粘接在密封层1表面。
本实用新型具有积极的效果：本实用新型在发泡密封件片材表面，用胶粘剂把聚氨酯薄膜与发泡密封件片材粘帖牢固，这样汽车传入发泡密封件片材的噪声的声波能量大部分被聚氨酯薄膜反射回发泡密封件，使得噪声驻留消耗在发泡密封件上，噪声在多孔间隙的发泡密封件里转变成了热能，从而实现降噪隔音减震密封的更好效果。
附图说明
为了使本实用新型的内容更容易被清楚地理解，下面根据具体实施例并结合附图，对本实用新型作进一步详细的说明，其中
图1为本实用新型的结构示意图。
具体实施方式
见图1，本实用新型具有密封层1，密封层1上设有隔音层3，密封层1与隔音层3之间设有粘接层2，密封层1为聚氨酯发泡形成的密封件片材，隔音层3为聚氨酯薄膜，密封层1与隔音层3之间通过聚氨酯胶粘剂连接。
以上所述的具体实施例，对本实用新型的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本实用新型的具体实施例而已，并不用于限制本实用新型，凡在本实用新型的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
