Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing a panel for a building using waste styrofoam,

More particularly, the present invention relates to a method for producing a building panel using waste styrofoam, which is discarded when it is used. More particularly, the present invention relates to a method of manufacturing a building panel by pulverizing waste styrofoam into various sizes, and adding a binder and an environmentally- And a method for manufacturing a panel for a building using waste styrofoam for cutting a molded article to a desired size.

In general, Styrofoam is called expanded polystyrene, styropol, foamed styrene, etc., and refers to a product made by expanding polystyrene by the action of a blowing agent.

These styrofoam features are white and light, and they are widely used as insulation materials not only in the construction field but also in the industry as well as being excellent in water resistance, heat insulation, soundproofing and buffering properties, And is widely used as a packaging material for transportation of articles which are damaged easily or lightly.

Styrofoam used for transportation packaging materials and building materials is left as waste disposal styrofoam when it is used.

That is, waste styrofoam used as a packaging material for transportation of articles, waste styrofoam used as a building material, and waste styrofoam cut in the process of processing packaging materials or building materials are mostly discarded as they are, Styrofoam has been disposed of or incinerated and discarded.

When the waste styrofoam is buried, it does not decay well and causes pollution of the soil. In case of incineration, a large amount of noxious gas is discharged to cause pollution of the environment, and also there is a problem in cost due to landfill and incineration .

Since the waste styrofoam which has a possibility of recycling causes an enormous loss in view of the fact that the resource is absolutely scarce in Korea, it is urgently required to develop a technique for effectively recycling waste styrofoam.

As described above, according to the present invention, it is possible to recycle used waste styrofoam as a building panel by using waste styrofoam as a panel for a building, so that the cost of treating waste styrofoam incinerated with existing waste is not required, The problem is eliminated and the resources are saved.

In addition, by adding an eco-friendly material in which anion is generated in the crushed raw material and a binder having a property suitable for a building panel, the waste styrofoam used can be recycled as a high quality building panel.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flowchart showing a method for manufacturing a panel for a building using waste styrofoam according to the present invention; FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a flowchart showing a method for manufacturing a panel for a building using a waste styrofoam according to the present invention, wherein a method for manufacturing a panel for a building using waste styrofoam according to the present invention comprises a crushing step (S100) Step S200, forming step S300, and completion step S400 are sequentially performed.

The crushing step (S100) is a step of crushing waste styrofoam to produce regenerated styrofoam. The crushed waste styrofoam is first crushed to a size of 45 to 55 mm using a crusher, and then the crushed crushed material is crushed again using a crusher Followed by secondary crushing to a size of 1 to 5 mm.

In order to compensate for the disadvantage that the shredding efficiency is lowered when the pulverized styrofoam is crushed to a size required for the optimum styrofoam size, the shredding operation is sequentially performed in the shredding step (S100).

Also, in the final crushing step (S100), the crushed waste styrofoam is crushed to a size of 1 to 5 mm by using crushed crushed materials of various sizes, and when the panel for a building is completed through the steps described below, crushed pieces of various sizes To increase the density and to maximize the effect of heat insulation and sound insulation.

The stirring step S200 is a step of stirring the crushed material in the crushing step S100 together with the binder and the environmentally friendly material in an agitator, and stirring the crushed material crushed in the crushing step S100 into a building panel .

In the stirring step S200, 30 to 50 parts by weight of the binder and 0.1 to 1 part by weight of the environmentally friendly substance are mixed and stirred based on 100 parts by weight of the crushed product in the crushing step S100, When the binder is mixed in a small amount, the adhesion between the crushed materials is not achieved. When the binder is mixed more than the above range, the amount of the binder is excessively large, which causes waste of the material, and the weight of the waste styrofoam, It will not be able to function.

When the environmentally friendly materials are mixed in the above-mentioned range, the optimum mixing ratio to exhibit eco-friendly functions in molded articles molded into a building panel is obtained.

In the forming step S300, the agitated material stirred in the stirring step S200 is injected into a compressor and discharged to a mold die. When the material is completely discharged to a mold die, the mold die is disassembled and molded into a mold.

Here, the forming step S300 includes an inlet for connecting to the compressor. When the molding is completed, the separating mold is used to inject the agitated material discharged from the compressor into the mold And then, when the agitated material is formed, the molded part is cut into a shape of an inlet port.

It is also preferable that the mold frame is made of a rectangle in the form of a typical building panel.

In the completion step (S400), the molded product after the molding step (S300) is dried in a drying furnace maintained at 40 to 60 ° C for about 3 to 7 hours, and then cut into a desired shape, that is, a length of a panel for a building.

Since the above steps are carried out sequentially, it is possible to recycle the waste styrofoam used as the building panel by using the waste styrofoam to be used as a building panel, so that the disposal cost of the waste styrofoam incinerated by the existing waste is not separately consumed, And it has the effect of saving resources.

Here, the binder used in the stirring step (S200) is composed of 75 to 80% by weight of an acrylic binder, 10 to 15% by weight of a flame retardant, and 7 to 12% by weight of a fluorine-containing water repellent agent.

Among the components constituting the binder, the acrylic binder is usually used as an adhesive most commonly used in the production of styrofoam. When the acrylic binder is composed of 75 to 80% by weight of the binder, even if the flame retardant and the fluorine- do.

The flame retardant dilutes the concentration of materials that can be burned on the gas among the components constituting the binder and significantly reduces the amount of smoke released when the combustion material is burned, so that it is possible to exhibit sufficient adhesion even at high temperature or high temperature If the blending amount is less than the above range, the function of the flame retardant is lost. When the blending amount of the flame retardant is more than the above range, waste of the material is caused, It is preferable that the weight is in the above range.

In addition, the fluorine-based water repellent agent constituting the binder can provide the water repellent performance to the building panel manufactured according to the present invention. When used as a heat insulating material and a soundproofing material, rapid water repellency can be achieved even when condensation water is generated due to a difference in temperature from the outside. The heat insulating performance can be maintained.

In addition, since the fluorine-containing water-repellent agent has a water-repellent performance deteriorated by a neutralizing action at a temperature of 50 ° C or higher due to its nature, it is preferable that the binder is stirred while being cooled to 40 ° C.

Meanwhile, the eco-friendly material used in the stirring step (S200) is preferably one or a mixture of at least one kind selected from the group consisting of charcoal powder, tourmaline powder and loess powder. The eco- When used as a panel for use, anion that is beneficial to the human body is released, thereby enabling antimicrobial and moisture-proof effects to be achieved.

On the other hand, the building panel manufactured by the above manufacturing method is made of any one of a sandwich panel, a heat insulating material, and a sound insulating material.
