Description

Wall body decorative panel with good sound insulation performance

Technical Field

The patent of the utility model relates to a ornamental material field, concretely relates to wall body decorative board that sound insulation performance is good.

Background

With the continuous promotion of the urbanization process of China, the noise pollution is continuously aggravated, various urban noises such as building noises and traffic noises seriously damage the physical and mental health of people, and nowadays apartments, office buildings and the like are mostly built by reinforced concrete due to the structural and bearing requirements, so that the sound insulation performance is poor, and the daily living and office requirements of people cannot be met. The aim of interior wall decoration is to improve people's living environment, also to protect the wall body simultaneously, has certain effect to improve the artistic effect of building, and the wall decoration of china at present is mainly with the coating, or adopts wall paper, wall paper etc. to decorate, and the material is mostly stone material, metal, ordinary plank etc. and the decorative mode is single, and sound-proof performance is low, consequently, the urgent need develop a wall decoration material that sound-proof performance is good, the texture is pleasing to the eye, simple installation.

SUMMERY OF THE UTILITY MODEL

According to the current situation of present wall decoration, the utility model provides a wall body decorative board that sound insulation performance is good, the texture is pleasing to the eye, have certain shockproof effect.

The wall veneer adopts the following scheme: the veneer consists of a wear-resistant layer, a shockproof layer, a sound absorption layer and a moisture-proof layer. The wear-resistant layer is formed by directly printing ink and is printed on the shockproof layer; the shockproof layer is an artificial board made of cork wood skin; the sound absorption layer is made of recombined bamboo or solid wood, is provided with a plurality of sound absorption grooves which are parallel to the vertical direction of the wall surface and are vertically communicated, and is connected with the shockproof layer by adopting aqueous polyurethane adhesive; the moisture-proof layer is a PVC plate, is fixed on the sound absorption layer by using a water-based polyurethane adhesive, and is assembled into a blank and subjected to cold press molding to prepare the wall veneer.

The thickness of the wear-resistant layer is 0.1-0.2 mm.

The thickness of the shockproof layer is 0.5-1.0mm, and the water content is 7-17%.

The sound absorption layer is made of 5-10mm of recombined bamboo or solid wood, the water content is 7-17%, sound absorption grooves which are parallel to the vertical direction of the wall surface and are vertically communicated are formed, the groove depth is 3-5mm, the groove width is 3-5mm, and one sound absorption groove is formed every 3-5 mm.

The thickness of the moisture-proof layer is 0.2-0.5 mm.

The utility model has the advantages that: rational in infrastructure, the texture is various, and sound insulation performance is excellent, has better shockproof effect simultaneously, extensively is applicable to places such as apartment, concert hall, school.

Detailed Description

Example 1: a wall veneer with good sound insulation performance is provided, the thickness of a finished product is 11.5 +/-0.3 mm, and the wall veneer is of a 4-layer structure and sequentially comprises a wear-resistant layer (1), a shockproof layer (2), a sound absorption layer (3) and a moisture-proof layer (4) from top to bottom.

Step 1) adopting a cork wood skin to process the shockproof layer (2) with the thickness of 0.8 +/-0.1 mm and the water content of 12-13%.

And 2) printing the wear-resistant layer (1) with the thickness of 0.2mm on the shockproof layer.

And 3) manufacturing the sound absorbing layer (3) by adopting the recombined bamboo with the thickness of 10 +/-0.1 mm and the water content of 12-13%, and arranging sound absorbing grooves which are 5mm wide and 5mm deep and are vertically communicated on the sound absorbing layer every 5 mm.

And 4) connecting the shockproof layer (2) with the sound absorption layer (3) by adopting a phenolic resin adhesive.

Step 5) a moisture barrier (4): a PVC plate with the thickness of 0.5mm is adopted, and one surface of the PVC plate is coated with a urea-formaldehyde resin adhesive and is connected to the sound absorption layer (3).

And 6) forming the plate blanks assembled in the steps 1-5 in a cold pressing mode, and aging and maintaining to obtain the wall body veneer with good sound insulation performance.

Example 2: the utility model provides a wall body decorative board that sound insulation performance is good, finished product thickness 8 +/-0.3 mm, 4 layers of structures are wearing layer (1), shockproof layer (2), sound absorbing layer (3) and dampproof course (4) from the top down in proper order.

Step 1) adopting a cork wood skin to process the shockproof layer (2) with the thickness of 0.6 +/-0.1 mm and the water content of 13-15 percent.

And 2) printing the wear-resistant layer (1) with the thickness of 0.1mm on the shockproof layer.

And 3) manufacturing the sound absorbing layer (3) by adopting oak with the thickness of 7 +/-0.1 mm and the water content of 13-15%, and arranging sound absorbing grooves which are 4mm wide and 3mm deep and are vertically communicated on the sound absorbing layer every 4 mm.

Step 5) a moisture barrier (4): a PVC plate with the thickness of 0.3mm is adopted, and one surface of the PVC plate is coated with a phenolic resin adhesive and is connected on the sound absorption layer (3).
