본 발명은 건축자재 제조용 분말 제조방법에 관한 것으로서, 특히 피브이씨(PVC, 이하 'PVC'라 한다.) 슬러지를 재처리하여 다양한 건축자재를 제조하는데 사용할 수 있는 분말을 제조하는 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder manufacturing method for building materials, and more particularly, to a method for producing a powder that can be used to manufacture various building materials by reprocessing sludge sludge (PVC). .

일반적으로 PVC 공장의 수처리장에서 발생하는 슬러지(이하 'PVC 슬러지'라 한다.)는 PVC 성분을 다량 함유하고 있음에도 활용 처를 찾지 못하여 대부분 폐기처리되고 있는 실정이다. 이는 자원이 부족한 우리나라의 실정에 비추어 볼 때 매우 안타까운 일이라 할 수 있다.In general, sludge generated in a water treatment plant of a PVC plant (hereinafter referred to as 'PVC sludge') is mostly disposed of because it does not find a use place even though it contains a large amount of PVC components. This is very unfortunate in light of the situation in Korea, which lacks resources.

상기와 같이 PVC 슬러지를 활용하지 못하고 있는 것은 다양한 용도로 활용할 수 있도록 재처리하는 방안이 마련되어 있지 않음에 기인한 것으로서, 이를 해소하여 다양한 용도로 활용함으로써 자원의 재활용을 꾀할 수 있도록 하여야 할 필요가 있었다.The failure to utilize PVC sludge as described above is due to the fact that there is no method for reprocessing to be used for various purposes, and it was necessary to solve the problem and use it for various purposes to recycle resources. .

근래 특허등록 제10-0838091-0000호(2008. 06. 09.) "피브이시 슬러지를 이용한 건축용 패널의 조성물"이 제안된 바 있으나, PVC 슬러지를 특별한 재처리 과정 없이 그대로 사용하는 것임에 따라 입도가 균일하지 못하여 PVC 슬러지를 다양한 용도로 활용하는데에는 제한이 있는 것이었다. Recently, the patent registration No. 10-0838091-0000 (2008. 06. 09.) "composition of building panels using fibish sludge" has been proposed, but the particle size according to the use of the PVC sludge as it is without special reprocessing process It was not uniform and there was a limit to using PVC sludge for various purposes.

본 발명은 상기와 같이 PVC 슬러지가 재활용되지 못하고 폐기되고 있는 문제점을 해결하기 위한 것으로서, PVC 슬러지를 재처리하여 다양한 용도로 재활용할 수 있도록 하는 것에 그 목적이 있다. The present invention is to solve the problem that the PVC sludge is not recycled and discarded as described above, the object is to re-process PVC sludge to be recycled for various uses.

본 발명에서는 PVC 슬러지를 재처리하여 균일한 입도의 분말을 형성하여 건축용 패널이나 타일과 같은 다양한 건축재를 제작하는 원료로 사용할 수 있도록 함으로써 상기의 목적을 달성한다.In the present invention to achieve the above object by reprocessing the PVC sludge to form a powder of uniform particle size to be used as a raw material for manufacturing a variety of building materials such as building panels or tiles.

본 발명에 따르면 PVC 슬러지를 재처리하여 다양한 용도로 사용할 수 있게 되는바, 자원을 재활용함과 아울러 환경을 보호하는 효과를 얻을 수 있고, 버려지는 PVC 슬러지를 재활용하여 다양한 건축재를 제조함으로써 저렴한 건축재를 제공할 수 있게 되는 유용한 효과가 유발된다.According to the present invention can be used for a variety of applications by reprocessing the PVC sludge, it is possible to obtain resources to recycle and to protect the environment, and to recycle the discarded PVC sludge to manufacture a variety of construction materials to produce a cheap building material A useful effect is made to be provided.

(S1) 건조단계 (S1) drying step

이 단계에서는 PVC 슬러지를 건조하여 준다. PVC 슬러지는 불순물이 함께 섞여 있는 상태로 상당량의 수분이 포함되어 있다. PVC를 제조하는 과정에서 발생한 슬러지는 수처리 과정을 거쳐서 형성되는 것임에 따라 자연스럽게 수분이 포함되어 있는 것이다. 이러한 PVC 슬러지를 건조하여 수분함유율이 10중량% 이하가 되게 하는 것이다.In this step, PVC sludge is dried. PVC sludge contains a significant amount of moisture with impurities mixed together. Sludge generated in the process of producing PVC is naturally formed by the water treatment process will contain water. The PVC sludge is dried so that the water content is 10% by weight or less.

상기 PCV 슬러지의 건조는 햇빛과 바람을 이용하여 자연건조를 하는 것이 바람직하나, 건조장치를 이용해 강제 건조하는 것도 가능함은 물론인바, 필요에 따라 적의 선택하여 실시한다. The drying of the PCV sludge is preferably natural drying using sunlight and wind, but it is also possible to forcibly dry using a drying apparatus.

한편, 상기와 같이 PVC 슬러지를 건조하는 과정에서 PVC 슬러지가 적당하게 건조되면 뭉쳐있는 PVC 슬러지를 두드려서 주먹만한 크기 정도의 작은 덩어리가 되게 분쇄하여 주는 것이 바람직하다. 망치나 막대를 이용해 뭉쳐있는 PVC 슬러지를 깨서 적당한 크기가 되게 하는 것이다. 이를 통해 큰 덩치로 뭉쳐 있을 때에 비해 건조 시간이 단축되는 효과가 유발됨과 아울러 건조된 PVC 슬러지를 미세하게 분쇄하기 위해 후술하는 분쇄장치(10)에 투입할 때 작은 덩어리를 투입할 수 있어 작업성이 개선되는 효과가 있다.On the other hand, when the PVC sludge is properly dried in the process of drying the PVC sludge as described above, it is preferable to pulverize the aggregated PVC sludge to a small lump about the size of the fist. Use a hammer or rod to break up the aggregated PVC sludge to a suitable size. This leads to the effect of shortening the drying time compared to when agglomerates into a large bulk, and also to insert a small lump when the pulverization device 10 to be described later to finely crush the dried PVC sludge, workability There is an improvement effect.

(S2) 분쇄단계(S2) grinding step

이 단계에서는 상기 S1 단계를 거쳐 건조가 완료된 PVC 슬러지를 미세한 분말 형태로 분쇄한다. PVC 슬러지 덩어리를 분쇄할 수 있는 분쇄장치(10)를 이용해 분쇄를 한다. 분쇄장치(10)는 컨베이어(20)를 통해 PVC 슬러지를 투입받아 분쇄를 하는 장치이다.In this step, the dried PVC sludge is pulverized into a fine powder form through the step S1. Grinding using a pulverizing device 10 that can crush the PVC sludge mass. The crusher 10 is a device that receives the PVC sludge through the conveyor 20 to grind.

이러한 분쇄장치(10)는 PVC 슬러지 덩어리를 미세한 분말 형태로 분쇄할 수 있는 것이라면 어느 것이라도 가능하나, 본 발명에서는 PVC 슬러지 덩어리를 맷돌로 갈듯이 분쇄하는 맷돌장치를 채택하였다.The pulverizer 10 may be any one as long as it can pulverize the PVC sludge lumps in the form of fine powder.

한편, 상기와 같은 맷돌장치로 분쇄를 하는 경우 맷돌장치가 마찰되면서 분쇄를 하는 것임에 따라 PVC 슬러지를 분쇄하는 과정에서 상당한 정도의 마찰열이 발생하게 된다. 그런데, 이렇게 발생 된 열은 PVC 슬러지의 물성을 변형시킬 수 있다. PVC가 그 재질 특성상 고온에서 물성이 변형되기 때문이다. 따라서, 분쇄하는 과정에서 물성의 변형이 발생하지 않도록 분쇄장치(10) 내부의 온도를 적정 온도로 유지하여 주어야 하는데, 그 온도는 60℃ 이하이고, 가장 적정한 분쇄장치(10) 내부 온도는 20~45 ℃ 범위가 되게 하는 것이다. On the other hand, in the case of pulverizing with the milling device as described above, as the milling device is crushed while rubbing, a considerable amount of frictional heat is generated in the process of crushing the PVC sludge. However, the heat generated in this way may change the physical properties of the PVC sludge. This is because PVC is deformed at high temperatures due to its material properties. Therefore, in order to prevent deformation of physical properties during the grinding process, the temperature inside the grinding apparatus 10 should be maintained at an appropriate temperature, the temperature of which is 60 ° C. or less, and the most suitable grinding apparatus 10 temperature is 20˜. To 45 ° C.

상기 PVC 슬러지를 분쇄하는 본 발명에 의한 분쇄장치(10)는 수냉식으로 온도가 조절되는 것이다. 이때, 발열량이 많아 분쇄장치(10)의 온도가 기준치 이상으로 상승하는 경우 본 발명에서는 질소가스를 상기 분쇄장치(10)에 투입하여 냉각을 한다. 센서의 감지에 따라 질소가스가 자동으로 투입되게 하는 것이다.The crushing apparatus 10 according to the present invention for crushing the PVC sludge is temperature controlled by water cooling. At this time, when the temperature of the pulverizing device 10 rises above the reference value due to the large amount of heat generated, nitrogen gas is added to the pulverizing device 10 to cool the present invention. Nitrogen gas is automatically injected according to the sensor's detection.

상기 질소는 분쇄장치(10)의 온도가 55℃에 이를 경우 투입이 개시되는 것으로서, 액체 상태인 것을 관을 통해 투입함으로써 온도를 낮추게 되는데, 불연성 기체이므로 고온의 환경에 투입되더라도 폭발의 우려 없이 안전하게 온도를 낮춰 줄 수 있는 것이다. The nitrogen is started when the temperature of the grinding device 10 reaches 55 ℃, the temperature is lowered by the input of the liquid state through the tube, because it is a non-flammable gas, even if it is introduced into a high temperature environment safely without the risk of explosion It can lower the temperature.

(S3) 분리단계(S3) separation step

이 단계에서는 분쇄된 PVC 슬러지에서 목적하는 입도의 분말을 분리하여 본 발명에 의한 건축자재 제조용 분말을 형성한다. 상기 S1 단계에서 분쇄된 PVC 슬러지 분말을 사이클론 집진기(30)에 투입하여 분리하는 것으로서, 본 발명에서는 5 마이크론 이하의 미세분말을 분리하여 사용하게 되는바, 입도가 5 마이크론을 초과하는 경우 성형성이 급격히 저하되기 때문에 5 마이크론 이하의 분말을 분리하는 것이다.In this step, the powder of the desired particle size is separated from the pulverized PVC sludge to form a powder for manufacturing building materials according to the present invention. As the PVC sludge powder pulverized in the step S1 to be separated into the cyclone dust collector 30, in the present invention is used to separate the fine powder of 5 microns or less, when the particle size exceeds 5 microns formability Since it is rapidly lowered, the powder of 5 microns or less is separated.

이상과 같이 사이클론 집진기(30)를 이용해 5 마이크론 이하의 분말을 분리하고 남은 나머지 기준치를 넘는 굵은 PVC 슬러지 분말은 다시 분쇄장치(10)에 투입하여 재분쇄하는 과정을 거친다. 이러한 과정은 PVC 슬러지 분말을 최대한 재활용하기 위한 것으로서, 이러한 재분쇄 과정을 통해 기준치 이상의 분말을 폐기하지 않고 다시 분쇄하여 사용할 수 있게 된다. As described above, the coarse dust collector 30 is separated from the powder of 5 microns or less, and the coarse PVC sludge powder remaining over the standard value is put into the grinder 10 again to undergo a process of regrinding. This process is to recycle the PVC sludge powder as much as possible, and through this regrinding process, it is possible to grind and use the powder again without discarding more than the reference value.

이상에서 설명한 바와 같은 S1, S2, S3 단계를 거쳐 도 3에 도시된 바와 같이 5 마이크론 이하의 입도로 되는 미세한 분말 형태의 건축자재 제조용 분말이 형성된다. Through the steps S1, S2, and S3 as described above, as shown in FIG. 3, a powder for manufacturing building materials in a fine powder form having a particle size of 5 microns or less is formed.

이러한 본 발명에 의한 건축자재 제조용 분말은 PVC 슬러지로부터 제조되는 것임에 따라 PVC 성분을 70~85중량% 포함하고 나머지는 불순물이 포함되어 있으나, 그러함에도 입도가 5 마이크론 이하로 형성된 것임에 따라 불순물이 어느 한 부분에 뭉쳐 있지 않고 PVC 성분과 균일하게 혼합되게 된다. 따라서 열 또는 압력성형시 불순물에 의한 영향이 최소화되므로 성형이 자유롭고 원활하여 다양한 건축자재의 원료로 쉽게 적용할 수 있게 된다.The powder for manufacturing building materials according to the present invention includes 70 to 85% by weight of the PVC component and the remainder contains impurities as it is manufactured from the PVC sludge, but the impurities are formed as the particle size is formed to 5 microns or less. It does not stick to any part and is mixed evenly with the PVC component. Therefore, since the influence of impurities during heat or pressure molding is minimized, the molding can be freely and smoothly and easily applied as a raw material for various building materials.

예를 들어 실내 바닥 마무리에 널리 사용되고 있는 PVC 재질의 데코타일 원료로 사용할 수 있다. 즉, 일반적인 데코타일은 2~3mm의 하층, 1~2mm의 중층, 5~7mm의 상층이 차례로 적층되어서 형성되는데, 상층은 불순물의 함유되지 않은 PVC를 사용하고, 본 발명에 의해 슬러지를 분쇄하여 얻은 분말은 불순물이 함유되어 있는 것임에 따라 외부로 드러나지 않는 중층 또는 하층을 형성하는데 적용하게 된다. 이때, 상층 또는 하층으로 적용하기 위해 본 발명에 의한 건축자재 제조용 분말을 성형하는 과정에서 열 또는 압력을 가해 성형하게 되면 불순물이 일부 섞여 있다 하더라도 미세하게 분쇄되어 있음에 따라 특정한 형태로 쉽게 성형하여 줄 수 있는 것이다.For example, it can be used as a decoration material of PVC material widely used for finishing indoor floors. That is, a general decor tile is formed by stacking a lower layer of 2 to 3 mm, a middle layer of 1 to 2 mm, and an upper layer of 5 to 7 mm, and the upper layer is made of PVC containing no impurities, and the sludge is crushed by the present invention. The obtained powder is applied to form a middle layer or a lower layer which is not exposed to the outside as it contains impurities. In this case, when applying the heat or pressure in the process of molding the building material manufacturing powder according to the present invention in order to apply to the upper layer or lower layer, even if some impurities are mixed, it is easily crushed into a specific shape as finely ground. It can be.
