Description

Technical Field

[0001] The utility model belongs to the technical field of wooden doors and relates to a multi-layer wooden door. Background Art

[0002] Multi-layer wooden doors are doors made of multiple layers of wood. This structure gives wooden doors many advantages. First of all, the multi-layer structure significantly enhances the stability and durability of wooden doors. Because the wood is dried and spliced ​​layer by layer, the door leaf is not easy to deform or crack, thus extending the service life. In addition, multi-layer wooden doors also have better thermal insulation and sound insulation effects, providing residents with a more comfortable indoor environment. If indoor multi-layer wooden doors do not have flame retardant and sound insulation effects, a series of problems may occur, which not only affect the quality of life of residents, but also pose a potential threat to their safety.

[0003] If the sound insulation performance of indoor wooden doors is poor, external noises such as traffic noise and human voices can easily enter the room, breaking the tranquility of the indoor environment and affecting the rest and work of the residents. If the wooden doors are not flame retardant, once a fire occurs, the wooden doors may be quickly engulfed by the flames and cannot effectively prevent the spread of the fire. This will not only accelerate the spread of the fire, but also may make it difficult for the residents to escape and rescue.
