The clean soft glue is clean soft glue sold on the market. The sound insulation powder and the clean soft glue are mixed evenly to obtain the sound insulation soft glue, which can be filled to the position to be sealed, and the sound insulation soft glue can be recycled.

[0012] As a preferred embodiment of the present invention, the sound-insulating agent powder is aerogel powder, hollow glass microspheres or expandable microspheres. The aerogel powder can be silicon oxide aerogel powder, crushed aerogel scraps or recycled aerogel powder.

[0013] The utility model directly fills the bottom of the soundproof cover with soundproof soft glue at the part that is easy to leak sound, and the soundproof soft glue can be recycled and reused after use, so there will be no dirt and grime, and it is easy to replace, there is no hygienic dead corner, and it can ensure the dual effects of hygiene and soundproofing. A sound-absorbing coating and a hammer pattern structure are added inside the soundproof cover to increase the noise reduction effect. It is simple to use, and the soundproof soft glue can be stored in a narrow and closed place at room temperature after recycling. The storage environment requirements are loose, and the fluidity is good. It can be used in different scenes to fit various gap shapes. The soundproofing agent powder used can also be the scraps of waste aerogel felt that have been crushed and processed, so as to reasonably utilize waste resources and alleviate the problem of waste disposal.
