Description
技术领域
本发明涉及吸音材料技术领域,具体涉及一种空调用降噪吸音板的制作工艺。
背景技术
随着人们对生活品质的要求不断提高,空调的噪音越来越受到消费者的重视,空调的噪音主要来源于室外机的风机、压缩机及其配管系统,其噪声不仅造成周围环境的污染,而且影响人们的生活和工作,如何削弱多频段的声波,改善音质成为空调科研人员工作的重心之一,目前,主要是通过阻止声波传播的原理来实现消声,即在压缩机上包裹一层隔音棉,吸收压缩机向外辐射的各频率声波能量,以达到大幅度降低噪音的效果,但效果并不是很明显,此外,压缩机振动并通过底部螺栓和配管传到空调箱体上,引起箱体结构的振动,也是引起噪声的重要来源之一,因此,还需在现有技术的基础上进一步改善。
发明内容

1)将第一EVA泡棉层的下表面用水性EVA处理剂进行处理,干燥;
2)在第一EVA泡棉层的上表面上依次平铺聚酯吸声棉层、第二EVA泡棉层和无纺布层,加热,压合成型,冲孔,切割休整,得复合材料;
3)将复合材料通过螺钉固定在空调外机箱体内的部件上,且第一EVA泡棉层的下表面朝向部件表面。
优选地,所述第一EVA泡棉层、聚酯吸声棉层、第二EVA泡棉层和无纺布层的厚度分别为2-3mm、3-5mm、3-5mm、0.2-0.4mm。
优选地,所述第一EVA泡棉层、聚酯吸声棉层、第二EVA泡棉层和无纺布层的厚度分别为2.5mm、4mm、4mm、0.3mm。
优选地,所述压合成型包括一次压合成型和二次压合成型,经压合成型处理后得到的复合材料的周边厚度要低于其它地方厚度。
有益效果:本发明将EVA层用水性EVA处理剂处理后,增加其表面粗糙度,将其朝向部件表面,不容易滑落,制得的降噪吸音板效果优良,具有缓冲、抗震、吸音的作用,有效阻止空调外机中各部件产生的各频率声波穿过箱体,削弱声波能量,从而大幅度降低外机产生的噪音,有很大的应用价值。
