(1) By specially mixing and forming main raw materials such as rice hull and styrofoam particles, the air gap of the particles can be enlarged to significantly reduce the noise between floors.

(2) Since it is composed of an elastic material that can absorb external shocks using the physical properties of the raw material, there is an effect of preventing injuries.

Referring to this, the present invention is configured to have a panel body of a rectangular plate shape having a predetermined thickness and area by mixing the urethane binder in chaff, rubber chips, Schiropol particles and silica sand, and then compressed in a mold. By mixing chaff, rubber chips, Schiropol particles and silica sand and binding them with a urethane binder, a panel body having a rectangular plate shape is obtained.

Specifically, 10 to 20% by weight of chaff, 20 to 30% by weight of rubber chips, 5 to 10% by weight of Schiropol particles, and 25 to 35% by weight of silica sand are added to the stirrer and mixed them first, and then to the first mixed material. After the urethane binder is added to mix the materials in a secondary manner, the secondary mixed materials are added to a molding mold and compressed using a compressor or the like to form a panel body having a rectangular plate shape.

Before using chaff as the main material of the eco-panel of the present invention, the use of wood flour as a main material was first considered. However, the wood flour (sawdust) has a moisture hygroscopic property, and therefore, the chaff has been adopted. Since the ecopanel of the present invention enters the floor of the building, when wood powder is adopted, the wood powder has an unpleasant smell as the wood powder decays. Since chaff has a property of absorbing almost no water, and has a property of not decaying even if left alone throughout the year, it is adopted as the main material of the ecopanel of the present invention. In other words, the chaff was judged to be the most suitable eco-panel main material in that it has excellent water permeability, extremely low water absorption ability, and does not rot easily. The chaff is the main ingredient of the ecopanel, considering that it must be maintained.

When designing the eco panel, it is important to be able to implement the eco panel at a low price while maintaining the proper thickness of the panel. The main ingredient of the chaff can satisfy this requirement.

By adding the chaff as a main component, it is possible to obtain voids in the molded eco-panel itself. Since the eco panel of the present invention enters the floor of a building, it must be resistant to moisture, and also has a property of blocking sound waves (noise) transmitted by forming voids.

Therefore, in the present invention, while chaff has a strong resistance to moisture, to obtain a sound wave blocking effect through the formation of voids. As mentioned above, I tried to use wood powder, which is not good because it absorbs a lot of moisture and it decays in the long term, and the amount of urethane binder is too high to prevent the wood powder from rotting. As a result, the amount of the urethane binder can be used in an appropriate amount range.

Here, in the present invention, it is meaningful to set the upper limit of the rice hull to 20% by weight or less.

When the chaff is more than 20% by weight, the amount of urethane binder is so high that the ecopanel itself is expensive, and the ecopanel itself has the appropriate cushion while maintaining the appropriate strength. This is a problem. In other words, chaff, rubber chips and styropol particles themselves are intended to give proper cushioning to the ecopanel, and urethane binders function to bind the other materials while surface coating the chaff, as well as styrofoam as well as chaff and rubber chips. It binds the particles and binds the silica sand, so the more chaff, the more the amount of urethane binders, the more expensive the ecopanel itself, and the harder the excess amount of urethane binders. It is difficult to have adequate panel stiffness.

In the present invention, however, in view of this, the upper limit value of the rice hull has a meaning in that the object is achieved by setting the upper limit of the rice hull to be less than 20% by weight.

Moreover, it is also meaningful to set the lower limit of rice hull to 10 weight% or more. The chaff is a form of pores in the eco panel itself to obtain a sound wave blocking (noise blocking) effect. If the lower limit of the amount of chaff is less than 10% by weight, the number of pores formed in the eco panel itself is too low, which is not good for noise blocking. Therefore, since the mixing ratio of rice hulls should be 10 weight% or more in the whole, in this invention, having set the lower limit of rice hulls to 10 weight% or more has meaning.

In addition, since the rice husk is a rice husk grain size of the rice husk can be said to be approximately the size of the grain of rice, in the present invention means that the chaff of the chaff is not broken in the state, but has a space-type chaff having a space therein. In other words, the threshing rice husk is used as it is after threshing. The reason for using the chaff as it is not broken is to give air to the eco panel itself after forming the kernel. Securing the void has a meaning as an effective blocking of noise.

In the present invention, the mixing lower limit of the rubber chip is set to 20% by weight or less, and the mixing upper limit of the rubber chip is set to 30% by weight or less so that the eco panel is not too soft or too hard. Too much rubber chip is undesirable because the panel is too soft and too little rubber chip requires more silica sand and urethane binders to enter.In this case, the panel is too hard, which is undesirable and inevitably less voids. In the present invention, the upper limit and the lower limit of the mixing ratio of the rubber chip are set in the above range so as to retain the appropriate stiffness (softness) by the rubber chip while maintaining the proper stiffness (hardness).

On the other hand, the size (volume) of the rubber chip is also important. The particle size of the rubber chip employed in the present invention is in the range of 5 mm to 7 mm.

The reason for not using a smaller rubber chip (approximately 2mm to 3mm rubber chip) is that the price is high, so the overall cost of the panel is high, and the softness and hardness required by the eco panel are not obtained.

When using rubber chips with sizes smaller than the range of 5mm to 7mm, binding with a urethane binder fills the space with a fine rubber chip, making it a sealed panel, which prevents voids, that is, a compact sealed panel with voids. As a result, the strength of the panel is relatively high, but the softness required by the eco-panel is not achieved, so the sound insulation effect is relatively inferior.

Therefore, the present invention used a rubber chip size of 5mm to 7mm, and by using the rubber chip of this size range, it is possible to obtain the effect of lowering the cost, as well as the ductility (softness) originally required in the eco-panel It solves the problem that the sound insulation effect is relatively lowered.

In addition, the present invention uses a non-uniform particle shape as a rubber chip, and since the voids are secured as much as the non-uniform particle shape of the rubber chip, this is also useful for improving sound insulation effect and proper softness in an eco panel.

The rubber chip has a larger area than the mixed materials (chaff, styrofoam particles, silica sand) of which the rubber chip has a different particle size, and the rubber chip occupies a larger area due to the irregular shape of the rubber chip. And silica sand can form relatively more voids in the state bound by urethane binders, so that the softness of the eco panel itself can be efficiently ensured, and it is easier to absorb shock by increasing the shock absorption amount, and furthermore, In other words, the price is lower.

Styropol particles enter together with the chaff and rubber chips, and the mixing amount of the styropol particles is set in the range of 5% by weight to 10% by weight.

The reason for using the styrofoam particles in the present invention is to properly maintain the volume of the ecopanel itself. Styrofoam particles are used in the form of rounded particles. As the styrofoam particles become rounded like this, when the irregular shape of the rubber chips and the shape of the rice husks are mixed, the natural pores are formed in the panel itself. Solid sound or air sound is absorbed or prevented from functioning faithfully.

Styrofoam particles also serve the purpose of maintaining voids. It is necessary to maintain the voids in the panel itself to maintain excellent thermal insulation due to the panel and to create a pocket shape inside the panel. When the size of the styrofoam particles exceeds a certain critical size, the characteristics of the chaff can be rather eaten. Size should be based on chaff.

Styrofoam is added as a supplement to the rice husk, and to make the chaff's characteristics properly used, it is desirable to reduce the styrofoam particle size to a little smaller than the size of the rice husk. If the size of the styrofoam particles is greater than that of the rice husk, the styrofoam is not a material that plays a major role in the rice hull and the panel, but the styrofoam replaces the main function, thus deviating from the characteristics of the styrofoam that is added as a supplement to the rice hull.

Therefore, in the present invention, the styrofoam particle size is slightly smaller than the rice husk on the basis of the chaff, the size of the styrofoam particles is preferably used in the 0.1mm to 0.5mm, in some cases the size of the styrofoam particles 1mm You can also use something about 2mm.

Here, it is also meaningful to set the mixing range of the styrofoam particles in the above range. That is, if the lower limit of the amount of the styrofoam particles is set to 5% by weight or less, there is insufficient pore formation between the chaff particles and the rubber particles to be mixed together, resulting in a lack of natural pore formation. In the present invention, since the reliability may be lowered, the lower limit of the styrofoam particles is set to 5% by weight or more in order to satisfy thermal insulation soundproofing and the like.

Styrofoam particles play a role in filling voids and large sizes between each other.If the mixed amount of styrofoam particles is 5% by weight or less, the hard silica will replace it, so the overall strength is too strong and the shock absorption amount is large. There is no choice but to fall. Therefore, it is undesirable to put the mixed amount of the styrofoam particles less than 5% by weight.

In addition, the upper limit of mixing of the styrofoam particles is set at 10% by weight so as to be less than the amount of chaff mixed. In other words, the mixing amount of the styrofoam particles is set at a lower limit of 5% by weight and an upper limit of 10% by weight so that the amount of the styrofoam particles is less than that of the rice husk, thereby fulfilling the function of complementing the pores of the panel itself together with the rice hull, while making pockets inside the panel to absorb shocks. It will exhibit functions such as noise absorption.

In other words, chaff and rubber chips should be the main materials for the suction and softness characteristics of the eco panel. When styrofoam is the main material, sound insulation and softness (softness) in the panel can be formed by the styro product. However, it will not be desirable to achieve the characteristics of the eco panel itself. Styrofoam is used for the purpose of maintaining voids between the chaff and rubber chips, which are mixed materials, and the size of the styrofoam particle is also used.

Therefore, if the mixed amount of the styrofoam particles is used more than 10% by weight, the overall strength decreases due to the softness of the styrofoam. Thus, when the strength of the panel decreases, a person may step down and sit down, so that the mixed amount of the styrofoam particles exceeds 10% by weight. It should be less, and it is inappropriate to increase the amount more than 10% by weight in order to absorb the impact amount.

As a result, the styrofoam particles of a smaller size than the chaff as described above, and by setting the amount of the styrofoam particles in the above range, while maintaining the main characteristics of the chaff, it is also possible to save the characteristics of the styrofoam as chaff complement.

Moreover, in this invention, a silica sand is mixed in 25 to 35weight% of a range. The chaff, rubber chips and styrofoam itself are intended to cushion the eco panel itself, so that the silica sand particles are mixed for the purpose of hardening the panel because the panel should not be too soft. In other words, in order to maintain the shape of the eco-panel, the gap between the chaff, the styropol particles and the rubber chip is filled with finer silica sand.

At this time, the silica sand uses a particle size of 500 mesh to 1000 mesh. The silica sand is bound together with other mixed materials by urethane binder to harden the eco panel itself.

As described above, each of the mixed materials (ie, rice hulls, rubber chips and styrofoam particles) sets the range of the mixing amount in the above-mentioned range to secure appropriate voids. When the mixing amount of the silica sand particles is set to the lower limit of 25% by weight or less, the silica sand The amount of is reduced so much that it is economically effective. However, the panel itself may be broken by external impact force because it does not meet the original strength required in the eco panel itself, and when the amount of silica sand particles is 35% by weight or more However, it is not desirable to add more than 35% by weight of silica sand because the strength of the panel itself is met but the gap of the panel itself is filled up so that the adaptability to the cushion is not satisfied.

Although urethane binder binds (binds) rice hulls, rubber chips and styropol particles together with silica sand, the eco-panel itself has a proper cushioning function and is easily broken by external impact forces. Therefore, the lower limit of the mixing of the silica sand is 25% by weight or more, and the upper limit is 35% by weight or less.

On the other hand, the method of manufacturing the eco panel of the present invention is also important. When the silica sand particles enter the chaff inside, it is not preferable in terms of suction, heat retention, or the like. Therefore, it is preferable to mix other mixed materials, bind them preliminarily with a urethane binder, and then put the silica sand last.

Therefore, in the eco-panel manufacturing method of the present invention, each blending material is mixed using a blender, but only chaff, styrofoam and rubber chips are first introduced into the blender, and the urethane binder is added to give a sticky state. To enter later.

When the chaff, styrofoam and rubber chips and silica sand are mixed together and a urethane binder is put together, the silica sand enters the chaff, and when all the silica sand particles enter the chaff, the silica sand can eliminate the role of securing voids. After the first mixing with a urethane binder and coating the chaff, styrofoam and rubber chips as the first, and then put the silica sand at the end, the silica will be filled into the chaff will not cause the phenomenon of voids.

On the other hand, since the particle size of the rubber chip is larger than the size of the chaff, there is no problem, but since the styrofoam particles are larger than the size of the chaff, the styrofoam particles may enter into the chaff broken during the blending process.

Therefore, chaff, rubber chips and urethane binders should be mixed first, urethane binders can be firstly bound, and later mixed with urethane binders with styrofoam and silica sand, which will be more preferable since the voids can be more reliably secured. .

Adding silica sand at the end is desirable to avoid the undesirable effects of filling the voids. As the specific gravity of silica sand is higher than the others when mixing each mixed material, the silica sand sinks down relatively at the time of mixing, which may result in poor mixing and poor uniform distribution. Sprinkle the silica sand little by little so that it doesn't sink.

Here, the component of a urethane binder is not water solubility but is about 95% to 99% of solid content to stick. Use the urethane binder as it is without the diluent or the hardening agent.

In order to organize the components of the eco-panel according to the present invention, the chaff and rubber chips are put first, and then the urethane binder is mixed and turned into a blender. The chaff is filled with a urethane binder and the chaff surface is coated and the rubber chip surface is coated. The rubber chip is larger than the rice husk, so it doesn't get into the rice husk.

In other words, the chaff and rubber chips are mixed, and the chaff and rubber chips are first mixed by urethane binder, then styrofoam and then silica sand to prevent the filling of the styrofoam and silica sand into the pores of the chaff and rubber chips. Do not put a large amount of silica sand at once, but mixes while watching the mix gradually. In this case, when the silica sand is 35% by weight or more, the gap is filled up, and the ecopanel strength is high, but sufficient voids on the cushion are eliminated. Therefore, it is not preferable to add more than 35% by weight of the silica sand. Since the bonding force of the eco-panel is too low to cause brittleness by external impact force, it is appropriate to set the lower limit of the amount of silica sand to 25% by weight.

If styrofoam is turned together with chaff and rubber chips, the styrofoam may get into the chaff.To prevent the styrofoam from entering, mix the chaff and rubber chips first, mix with a urethane binder, mix with styrofoam, and then add silica sand. It is desirable to mix.

In addition, in the ecopanel manufacturing method of the present invention, by adopting a method that focuses on the characteristics of the urethane binder, the manufacturing process time can be reduced by about half.

In the field of making a general rubber elastomer, it is cured by applying heat. The urethane binder has a property of being moisture-curable. When pressing in a natural moisture condition without applying heat to the urethane binder, approximately four hours until the desired elasticity is obtained. It takes about.

Therefore, urethane binders are moisture-curable, so if the moisture is fed first when manufacturing eco-panel, the urethane binder can react faster. This saves almost half the time of the existing process in the production of ecopanels.

In addition, since the eco-panel of the present invention is mainly installed in a special facility such as a school, it is primarily to use environmentally friendly materials and to achieve the purpose of excellent recycling (good recycling).

In the present invention, chaff is an environmentally friendly material, and rubber chips are preferable in that they are recycled, and silica sand is not detoxifying in that it is a natural product, and the degree of urethane binder and styrofoam affects the environment, and the urethane binder has a smelly property. In this regard, by performing the seasoning (ie, deodorization) operation in the manufacture of the present invention, it can be said that the desired goal is achieved in terms of eco-friendliness and excellent reactivation as a whole.

On the other hand, the eco-panel according to the present invention is more effective in noise barrier properties than the conventional products.

According to the above table and graph, it can be seen that the eco-panel of the present invention exhibits excellent sound absorption characteristics for light weight noise, while having excellent sound absorption for most weight noises, although not perfect for weight noises.

The weight noise is mostly caused by the vibration applied to the facility itself, and since the weight noise is transmitted through the facility wall rather than through the eco panel of the present invention, it is a problem of the eco panel itself. It is not a matter of the system's weight noise transmission system.

As a result, the eco-panel of the present invention completely blocks light weight noise and can be said to be an improved product compared to the conventional one in weight efficiency even in weight noise.

Therefore, the eco-panel 10 of the present invention can significantly reduce the interlayer noise of the building by expanding the air gap of the particles through a special blending and molding of main raw materials such as chaff and styrofoam particles, and absorbs external shocks sufficiently. Because it is made of elastic material that can be used, the place where young students live, such as school, absorbs shock even when the young student hits the floor, so it can contribute enough to prevent the possibility of serious injury. Can be.

Meanwhile, in the present invention, a urethane binder is mixed with the chaff, rubber chips, Schiropol particles, and silica sand to form a rectangular panel-shaped panel body 12 having a predetermined thickness and area. At least one of the two circumferential portions parallel to each other among the circumferences is provided with a stepped portion 114, and the other has a structure in which the seating groove 116 is formed.

Therefore, as shown in FIG. 3, the eco-panel 10 adjacent to each other may be constructed in such a manner that the seating groove 116 and the stepped portion 114 are joined to each other.

In addition, a plurality of sound absorbing holes 22 are formed in the panel body 12, and a plurality of first sound absorbing holes 22a are formed in one direction, and the second sound absorbing relatively smaller in diameter than the first sound absorbing holes 22a. A plurality of holes 22b are formed in one direction. The first sound absorbing holes 22a and the second sound absorbing holes 22b are alternately formed in the panel body 12. In addition, the sound absorbing hole 22 has a structure in which the lower portion is closed without being opened to increase strength, sound absorption efficiency and the like.

Sound-absorbing hole 22 has the effect of absorbing the ambient noise to reduce the floor noise of the building. In the present invention, the sound-absorbing holes 22 are configured to have a relatively large diameter of the first sound-absorbing holes 22a and the second sound-absorbing holes 22b.

Accordingly, the construction is performed by arranging a plurality of ecopanels adjacent to each other at the time of construction. As shown in FIG. 6, other neighboring ecopanels in the connection groove 16 of one of the ecopanels 10 are illustrated. Since the connecting protrusions 14 of 10) are coupled to each other in a ring coupling manner, the eco panel 10 installed on the floor or wall of the building does not have to be separated from each other, and furthermore, in terms of construction reliability and the like. Reference numeral 4 of FIG. 6 shows a wooden floor, and recently, in a school where young students are living, they are being constructed as a wooden floor 4 again to prevent serious injuries due to the impact caused by the floor. The eco panel 10 of the present invention is constructed under the buffer flooring material 4 which is not hard like a wood floor and can absorb shocks when an object collides, since the eco panel 10 itself is made of a cushioning material. In other words, it can contribute to the prevention of serious injuries by absorbing the impact of young students on the floor (4).

On the other hand, Figures 7 to 9 show a third embodiment of the present invention, according to the present invention according to Figures 7 to 9, on the upper surface of one side circumference side of the two circumferential portions of the panel body 12 parallel to each other The upper connecting protrusion 114 and the upper connecting groove 116 extending in the direction parallel to the width direction, and the upper connecting protrusion 114 and the upper connecting groove 116 on the bottom surface of the other end peripheral side of the panel body 12 and The lower connection protrusion 214 and the lower connection groove 216 extend in parallel with each other. The upper connecting protrusion 114 and the upper connecting groove 116 are adjacent to be formed side by side, the lower connecting protrusion 214 and the lower connecting groove 216 are also formed adjacent to each other side by side.

Therefore, as illustrated in FIGS. 8 and 9, when the plurality of eco panels 10 are disposed and constructed to be adjacent to each other, the upper connection protrusion 114 and the upper connection grooves of the one eco panel 10 ( The lower connection groove 216 and the lower connection protrusion 214 of the other eco-panel 10 are coupled to each other in an engaging manner such that the ring is engaged with each other, and the effect thereof is illustrated in FIGS. 4 to 6. Since it is the same as that, duplicate description will be omitted.

In addition, the present invention has a structure in which the panel body 12 further includes a plurality of sound absorbing holes 22 penetrating from the upper surface to the lower surface, and the sound absorbing holes 22 further provide noise such as air sound and solid sound. By absorbing reliably, the noise phenomenon between building floors can be reduced more reliably.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and it will be apparent to those skilled in the art that various substitutions and changes can be made without departing from the technical spirit of the present invention. will be.
