Abstract

本实用新型公开了一种吸音绵,包括PP棉层、设于PP棉层底面的不干胶层以及设于PP棉层表面的铝箔,所述的铝箔上设有凹凸相间的压纹,所述的不干胶为高黏度不干胶贴纸;本实用新型的PP棉层上设有铝箔,铝箔上设有规则的压纹,这样相较现有的吸音绵具有更高的抗拉力强度和更好的隔热效果。

Description

一种吸音绵
技术领域
本实用新型涉及一种汽车用吸音绵。
背景技术
目前广泛用于汽车内饰领域的吸音绵,多是置于汽车引擎防护罩内侧,用于吸收引擎所发出的噪音。这些吸音绵多为合成纤维混纺而成,产品的粘接度不够,抗拉力强度比较差,而且隔热效果有限,不能满足汽车工业对此种产品的要求。
实用新型内容
本实用新型的目的是提供一种抗拉力强度高、隔热效果好的吸音绵。
本实用新型解决其技术问题所采用的技术方案是:一种吸音绵,包括PP棉层、设于PP棉层底面的不干胶层以及设于PP棉层表面的铝箔,所述的铝箔上设有凹凸相间的压纹。
其中,所述的不干胶为高黏度不干胶贴纸。
本实用新型的有益效果是:PP棉层上设有铝箔,铝箔上设有规则的压纹,这样相较现有的吸音绵具有更高的抗拉力强度和更好的隔热效果。
附图说明
图1是本实用新型的剖视图。
具体实施方式
下面结合附图对本实用新型作进一步详细说明。
参照图1所示,本实用新型公开了一种吸音绵,包括PP棉层2、设于PP棉层2底面的不干胶层1以及设于PP棉层2表面的铝箔3,所述的铝箔3上设有凹凸相间的压纹,所述的不干胶层2为高黏度不干胶贴纸;本实用新型的PP棉层2上设有铝箔3,铝箔3上设有规则排列的多个六边形压纹,这样相较现有的吸音绵具有更高的抗拉力强度和更好的隔热效果。
以上所述的仅是本实用新型的优选实施方式,应当指出,对于本领域的普通技术人员来说,在不脱离本发明创造构思的前提下,还可以做出若干变形和改进,这些都属于本实用新型的保护范围。
