Description

Sound insulation wooden door

Technical Field

The utility model belongs to the technical field of the timber, concretely relates to timber gives sound insulation.

Background

Wooden doors, i.e. wooden doors. It is widely applicable to civil and commercial buildings and houses.

The wooden door can be divided into a solid wood door, a full wood door and a solid wood composite door according to different materials. The solid wood door is produced by taking natural logs obtained from forests as door cores, drying, and then scientifically processing through the procedures of blanking, planing, tenoning, drilling, high-speed milling and the like. The all-wood door takes natural log wood as a door core, and the balance layer adopts a three-ply board to replace a density board; the natural characteristic and the environmental protection property of the log are possessed in the process, and the problem of unstable performance of the log is solved. However, although the solid wood door and the whole wood door are beautiful and strong in impact resistance, the price is relatively high. The door core of the solid wood composite door is formed by bonding pine, fir or imported filling materials and the like, a solid wood frame is used as a door frame, a high-density board and a solid wood veneer are pasted outside the door frame, the edge of the door frame is sealed by solid wood lines, and the door frame is manufactured by high-temperature hot pressing. The solid wood composite door has the characteristics of small density, light weight, low price and the like, and is not easy to deform or crack, and the application is the most extensive. However, as the demand for quality of life increases, the sound insulation of the wooden door is receiving more and more attention. The high demand of people can't be satisfied to the syllable-dividing effect of current timber.
