Description

一种用于家用电器的高强度隔音过滤棉及制备方法
技术领域
本发明涉及隔音过滤棉制造技术领域，具体涉及一种用于家用电器的高强度隔音过滤棉及检验工艺。
背景技术
家用电器隔音是根据家电的性能、相应的材料、使用的条件，对家用电器产生的制冷机噪声、交换机与外壳产生振动的共鸣声、家电内组件因间隙或老化受挤压力产生的摩擦声等作细致处理，以提高家用电器工作的舒适性。而目前最有效的隔音方法就是在家用电器键部位添加隔音垫，使家用电器不但隔音，而且还可以起到隔热、隔尘的效果。但目前家用电器内部所使用的隔音垫多是普通的橡胶垫，虽然确实可以起到隔音的效果，但是确没有良好的吸音效果，良好的吸音效果可以消除家用电器部件的共振，从而使家用电器音频环境更加优良。
家用电器隔音过滤垫可应用于家用电器的各个部位，具有减震、吸音、隔热等特点，在越来越追求高性能、环境友好、轻量化、舒适度的时代，家用电器隔音效果与家用电器品牌一样成为人们选择家用电器的一个重要因素，因此对家用电器的要求越来越高。目前家用电器隔音过滤垫主要以再生纤维毡和PU发泡料为主。现有纤维毡隔音垫主要存在以下问题：
1、酚醛树脂加固的纤维毡气味较大，容易污染环境；
2、纤维毡裸露，容易引起挥发性有机化合物(VOC)超标，气味不能满足主机厂技术的要求；
3、饰面层韧性不足；
4、隔音效果不佳。
因此，研制一种用于家用电器的、高强度有效隔音过滤棉及检验工艺尤为重要。
