The invention discloses an automobile sound insulation and heat insulation pad and a processing technology thereof. The automobile sound insulation and heat insulation pad comprises a front wall plate, wherein a through groove is formed in the front wall plate, a connecting groove is formed in the outer surface of the front wall plate, a through connecting hole is formed in the front wall plate, the inner surface of the connecting hole is communicated with the inner surface of the connecting groove, and the front wall plate is composed of a base plate, sound insulation cotton, a cotton felt, a fiber plate, an aluminum foil plate, a sealing plate, a first adhesive film and a second adhesive film. The invention relates to the technical field of automobile front wall pads. According to the automobile sound insulation and heat insulation pad and the processing technology thereof, by arranging the base plate, the sound insulation cotton, the cotton felt, the fiber plate, the aluminum foil plate, the sealing plate, the first adhesive film and the second adhesive film, the sound insulation effect of the front wall plate is greatly improved, and by arranging the sealing plate, the peripheries of the sound insulation cotton and the cotton felt can be wrapped, the sound insulation cotton and the cotton felt are prevented from making contact with outside air for a long time and being aged, and the problem that an existing automobile front wall plate is low in sound insulation and isolation effect is solved through the combination of the structures.

    本发明公开了一种汽车隔音隔热垫及其加工工艺,包括前围板,前围板的内部开设有贯通的通槽,前围板的外表面开设有连接槽,前围板的内部开设有贯通的连接孔,连接孔的内表面与连接槽的内表面相连通,前围板由基板、隔音棉、棉毡、纤维板、铝箔板、密封板、第一粘膜、第二粘膜组成,本发明涉及汽车前围垫技术领域。该汽车隔音隔热垫及其加工工艺,通过设置基板、隔音棉、棉毡、纤维板、铝箔板、密封板以及第一粘膜和第二粘膜,从而极大的提高了前围板的隔音效果,且通过设置密封板,可以对隔音棉和棉毡四周进行包裹,避免其长期与外界空气接触老化,通过上述结构的组合解决了现有汽车前围板的隔音隔离效果较低的问题。
