The invention discloses a preparation method of an automobile dash sound insulation pad, wherein the preparation method comprises the steps: S1, material cutting: firstly selecting a cotton felt, a PU foam board and a sound insulation cotton board with proper sizes, then preparing a mold plate of an automobile dash board, putting the cotton felt, the PU foam board and the sound insulation cotton board on the mold plate, and cutting according to the shape of the mold plate. The invention relates to the technical field of sound insulation of automobile dash boards. In conclusion, according to the preparation method of the automobile dash sound insulation pad, through the working procedures from S1 to S4, the cotton felt and the sound insulation cotton plate are bonded through an adhesive, silicon-coated protective paper and a adhesive sticker, so that the cotton felt can be easily taken down, the disassembly difficulty is greatly reduced, the disassembly efficiency is improved, and the replacement cost is low due to the fact that the cost of the cotton felt is low; and finally, a side edge of a final cut edge is wrapped with an adhesive tape, the cut edge is prevented from being polluted, the side edge is wrapped and limited, and the situation that the use quality of the whole connection is affected due to damage of the side edge is avoided.
本发明公开了一种汽车前围隔音垫的制备方法,S1、材料切割:首先选取合适尺寸的棉毡、PU发泡板以及隔音棉板,然后再准备好汽车前围板的模具板,随之将棉毡、PU发泡板以及隔音棉板放于模具板上,对照模具板的外形进行切割;本发明涉及汽车前围板隔音技术领域。该汽车前围隔音垫的制备方法,综上所述,通过S1至S4的工作流程,棉毡和隔音棉板之间通过胶粘剂、涂硅保护纸以及不干胶进行粘接,使得棉毡可以轻易取下进行,极大的降低拆卸难度提高拆卸效率,且由于棉毡的成本较低使得更换成本较低,最后通过对最终裁边的侧边使用胶条进行包裹,避免裁边受到污染以及对侧边进行包裹限位,避免侧边损坏而影响连接整体的使用品质。
