A kind of decorative veneer for noise-reducing wall surface and preparation method thereof

Abstract

The invention discloses a decorative veneer for a wall that can reduce noise. The veneer sequentially includes a decorative ply, a shock-absorbing ply I fixed and bonded to the lower end of the decorative ply, and a shock-absorbing ply I from top to bottom. The sound-absorbing plate layer I fixedly pressed at the lower end, the sound-absorbing plate layer II fixedly pressed at the lower end of the sound-absorbing plate layer II, the shock-absorbing plate layer II fixedly pressed at the lower end of the sound-absorbing plate layer II, and the lower end surface of the shock-absorbing plate layer II are all coated with The rubber surface layer of the cloth is bonded to the release film layer at the lower end of the rubber surface layer. The invention also discloses a method for preparing a veneer for noise-reducing wall surface decoration, which includes the following steps: Step 1: preparing materials; Step 2: Plate opening; Step 3: Blank assembly; Step 4: Veneer forming; Step 5: Glue application; The combined structure of the ply II makes the entire veneer have good sound-absorbing and sound-insulating functions relative to the upper and lower directions.

Description

technical field [0001] The invention relates to the technical field of veneer preparation, in particular to a method for preparing a veneer for decorative surfaces that can reduce noise. Background technique [0002] Veneer is a kind of board for interior decoration. Its structure is simple. It is mostly used as a building material for synthetic plywood, and it can also be used alone as a decorative panel. According to its production method, veneer can be divided into processed veneer and synthetic veneer. Among them Processed veneer is made by direct peeling or sawing of wood, and synthetic veneer is divided into wood composite veneer and composite material veneer. Wood composite veneer is made of spliced ​​and pressed wood materials of different materials and structures. The composite material veneer is a plate formed by casting or pressing other materials than wood, such as a metal veneer and a plastic veneer. Although the veneer in the prior art solves the problem of dec...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing board with noise reduction function has a relatively simple internal structure. It only has the function of sound insulation or noise reduction on one side in dealing with noise, and cannot achieve both. Therefore, when the noise on both sides of the board is large , its noise reduction effect is not ideal;

[0004] 2. The veneer in the prior art often uses the whole sound-absorbing board layer for noise reduction. The sound-absorbing material itself has a loose structure, so it will reduce the overall strength of the veneer, resulting in the noise reduction of the veneer. Inability to balance performance and strength
