[0002] The soundproof door consists of a door leaf and a door frame. It is made of high-quality cold-rolled steel plates, cold-processed and formed. The door body is filled with sound-absorbing cotton, PU, ​​honeycomb structure, and sound insulation materials (the sound insulation materials mainly include damping rubber sheets and mineral wool sound insulation boards) according to the sound insulation level. It adopts advanced technology, unique design and special sealing production process, single and double cutting methods, and has excellent fire prevention, sound insulation, escape performance, stable performance, and is made of wood and steel with precision. Soundproof doors are divided into two types: wooden and steel, and the open space meets the user's use requirements.

[0003] The sealing strip is a sealing material installed on the door frame of the soundproof door. It is used to fill the gap between the door and the door frame to play the role of sound insulation, heat insulation, dust prevention and waterproofing. The sealing strips currently used are generally installed in the slots of the bottom frame of the soundproof door. The cross-section of the sealing strip is generally T-shaped, and the sound insulation is achieved by squeezing and deforming between the sealing strip and the ground. However, the elasticity of the sealing strip will decrease after a long period of use, and the sealing strip will often rub against the ground as the door body moves, and it is easy to be damaged, which in turn affects the sound insulation effect.
