The invention belongs to the technical field of automobile sound insulation pads, and particularly relates to an automobile sound insulation pad and a production method thereof.The automobile sound insulation pad comprises an upper felt body, a lower felt body, a supporting body and a heat preservation filling material; the upper felt body and the lower felt body are arranged side by side; the supporting body is arranged between the upper felt body and the lower felt body; the two opposite end faces of the supporting body are connected to the upper felt body and the lower felt body respectively. A filling cavity is formed among the support body, the upper felt body and the lower felt body; a filling guide hole is formed in the supporting body; one end of the filling guide hole is communicated with the filling cavity; the thermal insulation filling material is arranged in the filling cavity; and the volume of the foamed thermal insulation filling material is larger than that of the filling cavity. The heat preservation effect and the sound insulation effect can be guaranteed, and the phenomena of collapse and the like of the sound insulation pad are avoided.
本发明属于汽车隔音垫技术领域,具体涉及一种汽车隔音垫及其生产方法,包括上毡体、下毡体、支撑体和保温填充材料;所述上毡体与所述下毡体并排设置;所述支撑体设置于所述上毡体与所述下毡体之间;并且所述支撑体上的两个相对端面分别连接于所述上毡体、所述下毡体;所述支撑体、所述上毡体与所述下毡体之间设有填充腔体;所述支撑体内设有填充导孔;所述填充导孔的一端与所述填充腔体连通;所述保温填充材料设置于所述填充腔体的内部;并且所述保温填充材料发泡后的容积大于所述填充腔体的容积。本发明能够保障保温效果以及隔音效果,并且避免隔音垫出现塌方等现象。
