TECHNICAL FIELD [0001] The present invention relates to a sound-interference-induction type sound-proofing module and a noise-

The present invention relates to a noise interference induction type soundproof module and a noise interference induction type soundproof plate having the same.

In general, soundproof walls are installed at the edges of roads, railways, and the like, and are installed to prevent the noise caused by the vehicles from entering the surrounding houses and the like.

That is, a soundproof plate is stacked between the pillars and the pillars, which are installed on the floor, to block the noise generated in the vicinity of the road or the railway.

Such a soundproof plate is a sound absorption type, a sound insulation type, and a transparent type, and a sound absorption type soundproof plate is generally used most commonly.

However, the conventional soundproof panel is provided in the form of a panel-like plate, and the noise introduced through the front surface of the soundproof panel is reflected by the surface of the soundproof panel or flows through the hole formed on the surface thereof and is annihilated through the sound absorbent. There is a problem that the ambient noise is rather increased.

Further, when absorbing the incoming noise, there is a problem that the sound absorbing agent must be thickly installed.

In the case of a conventional soundproof panel, that is, a soundproof soundproof panel, the thickness of the panel must be increased, which results in a problem that the rigidity and the assemblability are remarkably deteriorated.

FIG. 2 and FIG. 3 are views showing a plurality of sound-interference-induction type soundproof modules of FIG. 1 connected to each other. 4 to 6 are views showing a noise interference induction type sound insulation board having a sound insulation interference type sound insulation module according to another embodiment of the present invention.

As shown in these figures, the noise interference induction type soundproof module 100 according to an embodiment of the present invention includes a plurality of noise interference holes 101 formed therein, A base plate member 105 having an arc-shaped inclined surface that is gradually reduced, and having a through hole 103 at the center thereof; An inlet 107 communicating with the through hole 103 at the rear of the base plate member 105 and a guide 107 having an inner diameter gradually increasing toward the rear so as to guide the noise introduced through the through hole 103 rearwardly, And a resonance member (111) including a body portion (109).

The base plate member 105 includes a plurality of noise interference holes 101.

The base plate member 105 is provided in a flat plate shape, and may be provided as a square flat plate, for example.

The base plate member 105 is provided with a structure in which a through hole 103 is formed at the center while having an arc-shaped inclined surface whose inner diameter gradually decreases from the front side toward the rear side, which is the noise inflow side.

That is, the base plate member 105 has a trumpet-shaped portion formed with a through hole 103 at the center.

By providing the trumpet portion on the base plate member 105 as described above, the incoming noise hits an inclined surface having an arc-shaped angle to cause reflection, diffraction, and mutual interference, thereby significantly reducing noise.

On the other hand, the noise reduced by the interference phenomenon (or the noise left over by the interference phenomenon) is sent backward through the through hole 103.

Of course, the noise passing through the noise interference hole 101a formed in the trumpet-shaped portion of the base plate member 105 and the noise passing through the noise interference hole 101b formed in the other portion also intersect with each other Reflection, diffraction, and mutual interference phenomenon.

Further, the base plate member 105 includes a flange portion 113 formed to extend rearward from the periphery of the through hole 103.

The flange portion 113 has a function of allowing the base plate member 105 and the resonance member 111 to be stably engaged and fixed while facilitating engagement and disconnection of the resonance member 111 to be described later with the inlet portion 107 .

On the other hand, in the case of the above-mentioned base plate member 105, the composition is composed of 100 to 100 parts by weight of wood hydroxide wood, 10 to 200 parts by weight of synthetic resin, 1 to 50 parts by weight of binder, 1 to 20 parts by weight.

The composition of the base plate member 105 preferably includes a metal hydroxide compound, and the metal hydroxide compound may be at least one of magnesium hydroxide and aluminum hydroxide, and preferably magnesium hydroxide.

The form of the metal hydroxide compound is not particularly limited, but may be various forms of powder, plate, or needle-like particles, and may preferably include powdery particles.

The average particle size of the powdery particles preferably includes 0.05 to 200 mu m, more preferably 0.1 to 100 mu m.

When the metal hydroxide compound is used, it is possible to improve the flame retardancy, endothermic and sound-absorbing properties, and it is possible to make the environmentally friendly base plate member 105 excellent in non-toxicity and harmlessness, .

However, when a large amount of a metal hydroxide compound is used, physical properties such as injection coloring property and injection heat stability are lowered.

On the other hand, it is known that the unicorn tree is an evergreen conifer belonging to the Japanese cabbage family, which is also called hinoki or cyphonus. It is known that the unicorn growing in Korea radiates more phytoncide than the pine or pine trees.

Here, phytoncide is a self-defense substance that a plant diverges to protect itself from the surrounding pathogens, and is generically referred to as a phenol compound such as terpene, an alkaloid component, a glycoside, and the like. Therefore, when wood flour, which contains a large amount of phytoncide, is used as wood flour, the antimicrobial activity is greatly increased and the antimicrobial substance which is advantageous to human is emitted.

The particle size of wood flour wood powder is not particularly limited, but it may be 80-120 mesh.

When the particle size of wood flour wood powder is less than 80 mesh, the particle size is too large, the dispersibility in the composition deteriorates, the flowability is poor when the pellet is produced, the productivity is poor, the surface becomes rough, And the strength effect of the product is insignificant.

If the particle size of wood flour wood is greater than 120 mesh, the particles may be too small to lower the strength and the grinding process time may become too long, resulting in lowering of overall productivity and cost competitiveness due to cost increase.

The wood flour wood flour may comprise, preferably, 1 to 100 parts by weight, more preferably 20 to 80 parts by weight, and most preferably 30 to 60 parts by weight, based on 100 parts by weight of magnesium hydroxide .

If the composition of the base plate member 105 contains 1 part by weight or less of antiseptic wood, the antimicrobial activity is insignificant. When 100 parts by weight or more of antimicrobial activity is contained in the composition, the surface of the base plate member 105 becomes rough It is difficult to produce a high-quality base plate member 105 due to a wood flaking phenomenon.

On the other hand, the synthetic resin is used to improve the strength of the base plate member 105, and may include 10-200 parts by weight, more preferably 30-150 parts by weight, relative to 100 parts by weight of magnesium hydroxide And most preferably from 60 to 90 parts by weight.

Here, when the synthetic resin is used in an amount of 10 parts by weight or less in the composition of the base plate member 105, durability is weakened and the impact strength is low. When the composition is used in an amount of 200 parts by weight or more, sound absorption and flame retardant effects become insignificant.

The synthetic resin is not particularly limited, but preferably includes at least one of ethylene propylene copolymer, polyethylene, polyproplylene and maleic anhydride, more preferably And may include an ethylene propylene copolymer.

When an ethylene propylene copolymer, polyethylene or polyproplylene is used, the weight average molecular weight is preferably 50,000 to 2,000,000 g / mol, more preferably 100,000 to 1,000,000 g / mol, 1,500,000 g / mol, and most preferably 500,000 to 1,000,000 g / mol.

On the other hand, the binder may include 1 to 50 parts by weight, more preferably 1 to 30 parts by weight, and most preferably 1 to 15 parts by weight, relative to 100 parts by weight of magnesium hydroxide .

Here, when the binder of the base plate member 105 is used in an amount of 1 part by weight or less, the effect of binding the composition is insignificant, and when it is 60 parts by weight or more, the strength is weakened.

Examples of such a binder include, but are not limited to, at least one of polypropylene, polyethylene, ethylene-ethyl acrylate, ethylene-methyl acrylate, ethylene-vinyl acetate, methacrylate, trimethylol propane, triacrylate and trimethylol ethylene , And more preferably polypropylene.

On the other hand, it is preferable that the composition of the base plate member 105 is different from that of the binder and the synthetic resin.

When the above-mentioned polypropylene or polyethylene is used, the weight average molecular weight may preferably be 50,000 to 2,000,000 g / mol, more preferably 100,000 to 1,500,000 g / mol, and most preferably, Can be from 500,000 to 1,000,000 g / mol.

If the weight average molecular weight of the binder exceeds 2,000,000 g / mol, the binding characteristics and processability may be deteriorated.

On the other hand, the anti-bending agent improves the strength by preventing bending deformation of the base plate member 105, and may include 1 to 20 parts by weight, preferably 1 to 20 parts by weight, relative to 100 parts by weight of magnesium hydroxide. 10 parts by weight.

When the amount of the antifoaming agent is less than 1 part by weight, the flame retardant performance of the composition of the base plate member 105 is lowered and warpage is generated and defective rate is increased. When the amount of the antifoaming agent is more than 20 parts by weight, .

Such an anticorrosive agent is not particularly limited but may be selected from talc, mica, fly ash, loess, vollastonite, titanium dioxide (TiO2), barium sulfate (BaSO4) and calcium carbonate (CaCO3) , And more preferably at least one of talc and talc.

Talc is commercially available as magnesium silicate hydrate.

In addition, the talc used includes silicic acid and magnesium oxide in addition to small amounts of aluminum oxide, calcium oxide and iron oxide.

The average particle size of such talc is 0.1 to 50 탆.

On the other hand, the above-mentioned fly ash is generally extracted from coal ash remaining at 1500 ° C to 2000 ° C. Since it is produced at a high temperature, it exhibits a high incombustibility and improves strength, water tightness, durability and reduces drying shrinkage .

Since the above-mentioned yellow loess is a sediment composed of silt-sized particles, its surface area is larger than that of general soil, and thus it has excellent adsorption ability, and it is used as a building interior material because of the effect of releasing far infrared rays and removing volatile organic compounds. .

The composition of the base plate member 105 may further include a pigment. Examples of the pigment include, but are not limited to, titanium dioxide (TiO2), mercury sulphide (HgS), sodium benzoate (C7H5NaO2), copper OH) 3, arsenic sulfide (As2S2), calcium carbonate (CaCO3), lead oxide (ZnO), iron oxide (FeO) and copper sulfide (CuS).

The pigment may include preferably 1 to 30 parts by weight, more preferably 1 to 15 parts by weight, based on 100 parts by weight of magnesium hydroxide.

Here, when the pigment of the base plate member 105 is used in an amount of 1 part by weight or less, the effect of pigment dispersion is insignificant. When the pigment is contained in an amount of 20 parts by weight or more, peeling occurs to produce a high quality base plate member 105 It is difficult to do.

On the other hand, the composition of the base plate member 105 may further include a lubricant and an ultraviolet ray preventive agent as additives in order to improve physical properties.

Here, the lubricant is for improving the surface properties of the product, and may include at least one of EBS, PE wax, and stearic acid.

Polymers which are composed of long-chain polymers are relatively viscous at high temperatures, so a lubricant is added to increase the dispersion of wood flour.

Such a lubricant may include preferably 1 to 45 parts by weight, based on 100 parts by weight of magnesium hydroxide.

The ultraviolet ray preventive agent may be selected from among Benzophenone, Benzotriazole, OrganoNickel and Hindered Amine Light Stabilizer (HALS), preferably Poly [[6 - [(1,1,3,3-tetramethylbutyl) amino] -s-triazine-2,4-diyl] - [(2,2,6,6-tetramethyl-4-piperidyl) imino] 2,2,6,6-tetramethyl-4-piperidyl) imino]].

The ultraviolet ray hardening agent may include 0.1 to 10 parts by weight, based on 100 parts by weight of magnesium hydroxide.

Meanwhile, the method of manufacturing the base plate member 105 includes the steps of putting the composition of the base plate member 105 into the compounding machine and mixing at a temperature of 150 to 250 ° C to obtain a starting material for synthesis; Extruding and cutting the synthetic raw material to obtain pellets; And injection molding the pellets at 50 to 200 DEG C by an injection molding machine.

Here, the characteristics of the composition, content, effect, etc. of the composition of the base plate member 105 include all of the above-mentioned contents.

The method of manufacturing the base plate member 105 will be described step by step.

First, the composition of the base plate member 105 is put into a blender and a synthetic raw material having a melt index of 3 to 4 g / 10 min is produced at a temperature of 150 to 250 ° C, preferably 180 to 230 ° C.

The melt index represents the weight of the resin flowing through the capillary for 10 minutes at a constant load and temperature. A measurement according to ASTM D-1238 may be used.

When the synthetic raw material having a melt index of 3 to 4 g / 10 min mentioned above is used, the mechanical strength is improved.

The synthesized raw material is extruded by a molding machine and cut to a length of 1 to 10 mm to produce pellets.

The pellets are preferably injected at an injection molding machine at a temperature of 50 to 200 DEG C, a pressure of 300 to 800 bar, and an injection speed of 600 to 900 rpm.
