The invention provides a light-weight sound insulation pad as well as a preparation method and application thereof. The light-weight sound insulation pad comprises a sound absorption layer, a bonding layer, an aerogel coating and a sound insulation layer which are sequentially arranged. According to the light-weight sound insulation pad, through a hierarchical structure design and replacement of a traditional heavy coating material with the aerogel coating, it can be guaranteed that the obtained light-weight sound insulation pad has the advantages of being excellent in sound insulation effect and light in weight, can effectively isolate noise such as wind noise and tire noise outside a cab, reduces the weight of parts, and thus improves the fuel efficiency of a fuel vehicle or the endurance mileage of an electric vehicle; and the aerogel coating is free of peculiar smell, low in VOC emission and free of influence on the air quality in a vehicle, meets control requirements on volatile organic compounds in air in vehicles, and is suitable for batch production and application.
本发明提供一种轻量化隔音垫及其制备方法和应用,所述轻量化隔音垫包括依次设置的吸音层、粘结层、气凝胶涂层和隔音层;所述轻量化隔音垫通过上述层级结构设计,以及采用气凝胶涂料替换传统的重涂层材料,可以保证得到的轻量化隔音垫兼具优异隔音效果和轻量化的优势,不仅有效隔绝了驾舱外的风噪、胎噪等噪音,还可以降低零部件的重量,进而有助于提升燃油车的燃油效率或电动车的续航里程;且所述气凝胶涂料无异味、低VOC排放,对车内空气质量无影响,满足对于车内空气挥发性有机物的管控要求,适合批量化生产和应用。
