Description

technical field [0001] The invention belongs to the technical field of composite wooden doors, and in particular relates to a preparation method of a multifunctional flame-retardant solid wood composite door. Background technique [0002] Solid wood doors refer to the materials used to make wooden doors are natural logs or solid wood laminates from forests. Most of the selected wood is precious wood, such as walnut, teak, red oak, ash, sapele and so on. There are two types of solid wood doors: the first type of solid wood is made of natural logs from forests, and there is only one kind of wood in the finished product, without veneer or board. The second type of solid wood composite, the material is that the door core is made of fir or other miscellaneous wood compacted density board and then veneered. [0003] Log solid wood doors take logs as the main material after drying, and then process them through blanking, polishing, tenoning, drilling and other processes to form s...
