As described above, the natural wood has an excellent texture, bending strength and good resistance to thermal expansion.

On the other hand, weakness in wetting is weak and corruption such as preservation treatment and fungus occurrence is a disadvantage for long term durability.

The present invention can obtain the wall sound barrier wall using the composite material using the wood fiber (cellulose), which has advantages of the natural wood and the weak points.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

The main component of the wood fiber of the present invention varies depending on species, but it is composed of 40-50 wt% of cellulose, 22-34 wt% of hemicellulose, 16-25 wt% of lean green and a small amount of extract.

The board (1) of the present invention allows the pellet, which is the main raw material, to be extruded by mixing wood fiber mixed with 70 wt% of wood fiber, 20 wt% of thermoplastic resin, 4 wt% of clay mineral, 5 wt% of antibacterial agent and other additives.

Further, the wall sound-absorbing wall 1 of the present invention is obtained by obtaining a pellet of a composite material in which a wood fiber mixed with 70 wt% of wood fiber, 20 wt% of thermoplastic resin, 4 wt% of clay mineral, 5 wt% of antibacterial agent, The pellets are extruded and formed in a secondary shape so that a plurality of hollow spaces are formed on the cross section and subjected to a known cooling process and a cutting process.

Example

The wood fiber of the present invention is composed of 40-50% by weight of cellulose, 22-34% by weight of hemicellulose, 16-25% by weight of lean green and a small amount of extract.

Here, as described later, the wood fiber having a high water immersion property is composed of 70 wt% of wood fiber, 20 wt% of thermoplastic resin, 4 wt% of colorant, 2 wt% of lubricant, 1 wt% of ultraviolet screening agent, 2 wt% of coupling agent, However, it is preferable to maintain the moisture content at 2 to 3% by the pre-mixing process.

Thus, the wood fiber is sufficiently dry in the dry, and the wood fiber is mixed with 70 wt% of the wood fiber, 20 wt% of the thermoplastic resin, 4 wt% of the colorant, 2 wt% of the lubricant, 1 wt% of the ultraviolet screening agent, So that the composition blended in the stirrer is sufficiently kneaded.

Further, the pellets of the composite material, in which the wood fiber is the main raw material, passed through the die hole and passed through the cutting and cooling process in the shape of a cylinder having a diameter of 3 to 4 mm and a length of 4 mm, is obtained by passing through an extruder having a cylinder temperature of 110 to 170 by indirect thermal method .

The main component of the composite of the present invention is wood fiber (cellulose) 60 to 80 mesh which is the main component of wood, and 70 weight% of unevenly sized organic compound material is to maintain the advantage of natural wood.

In addition, polypropylene, antibacterial agents, and other additives are functionally mixed materials that complement the disadvantages.

In order to maintain the smooth flow of the wood fiber, which is difficult to flow in the compression process by indirect heat, the main component, wood fiber, is preferably 60 to 80 mesh of non-uniform softwood species. In order to maintain smooth flow of the wood fiber, polypropylene, lubricant, heat stabilizer for anti- Blocking agents, coloring agents, and the like.

Next, the pellets of the composite are fed to a screw (not shown) holding a cylinder temperature of 130 to 180 at a biaxial extruder and passed through a mold mold to form a hollow portion 2 hollow in the longitudinal direction, (1) is formed. In the biaxial extruder, the screw is rotated by driving the driving motor to melt the pellet and transfer it to the mold mold.

Then, the wall sound-insulating wall 1 is cooled (cooled) while passing through the cooling cylinder, then guided to the guide rollers, and further cut to a predetermined length by a cutting machine to produce a finished wall sound- .

The reason for forming the composite pellet is to prevent the physical properties of the deck board, that is, the strength, the warpage, and the cracks from being generated through the uniform composition of the composition.

However, when the wall sound-absorbing wall is produced through a single extrusion molding by mixing the raw material as it is, the productivity is deteriorated due to shrinkage and expansion, and also the distortion and the length change are caused.

The sound barrier wall 1, which is the main raw material manufactured according to the present invention, is formed by forming a plurality of hollow portions 2 which are hollow in the longitudinal direction. Therefore, there is an advantage that the sound insulation effect of the wall can be enhanced by the hollow spiral wall 2 of the wall sound insulation wall 1, and the weight of the wall sound insulation wall 1 itself can be reduced.

As shown in Fig. 1 to Fig. 6, first, the rectangular shaped absorbent member 4 is placed on the lattice-shaped frame 3 produced according to the dimensions of the space to be installed and fixed by the fixing means.

In addition, the wall sound-absorbing walls 1 having the non-hollow portion 2 on the top of the absorbing member 4 are fixed by fixing means so as to be fixedly coupled with the wall-side sound-

In addition, the bracket 5 is fixed to the frame 3 in all directions, and is fixed to a wall surface to be installed by fixing means such as screws via the bracket 5.

In the present invention, the absorbent member 4 and the wall sound barrier walls 1 are installed on the frame 3, but wall sound barrier walls 1 may be additionally fixed to the back surface of the frame.

The wall sound-absorbing wall 1, which is fixed to the wall through the frame and the sound absorbing member 4, can increase the sound insulation effect by the hollow space of the wall and can obtain a texture similar to a natural wood, It is possible to provide a wall sound-absorbing wall which can obtain a natural-friendly texture of the wall, and can prevent warping and deformation of length.
