Description

분진 비산 방지를 위한 도포재 조성물{COMPOSITION FOR PREVENTING DUST SCATTERING}Coating material composition for preventing dust scattering {COMPOSITION FOR PREVENTING DUST SCATTERING}

본 발명은 탄광석 등 각종 입자상 물질이 적재된 야적장 등에서 분진이 비산되는 것을 방지하기 위한 도포재 조성물에 관한 것이다.The present invention relates to a coating material composition for preventing dust from scattering in a yard where various particulate matter such as coal ore is loaded.

탄광이나 제철소 등에는 석탄, 광석 등이 적치된 야적장이 형성되어 있는데, 이와 같은 야적장에서는 바람에 의해 분진이 비산되어 외부환경을 오염시켜 심각한 민원의 대상이 되고 있을 뿐만 아니라, 우천시에는 야적층이 씻겨내려가 수질오염을 야기시키기도 한다.Coal mines and steel mills are built with yards containing coal and ore. In these yards, dust is scattered by the wind, polluting the external environment, and the pit layer is washed in rainy weather. It can go down and cause water pollution.

일반적으로 탄광석 등 입자상 물질의 야적장에서 분진 비산 방지를 위한 방법으로는 방진포를 설치하거나, 일정한 높이의 방진벽을 설치하고 살수하는 방법, 또는 표면경화제를 살포하는 방법 등이 행해지고 있다. 그러나, 이러한 기존의 방법들은 비용이 많이 들거나 작업 및 관리가 어려운 단점 등을 갖고 있다.In general, as a method for preventing dust scattering in a yard of particulate matter such as coal ore, a method of installing a dustproof cloth, installing and spraying a dustproof wall having a constant height, or spraying a surface hardening agent is performed. However, these existing methods have disadvantages that are expensive or difficult to work with and manage.

예를 들어, 단순한 살수방법에 의한 분진 비산방지는 설비 등은 간단하나 분진 비산방지효과가 미흡하다. 한편, 한국 특허출원 공개 제1999-079852호에서는스티렌과 부타디엔을 주성분으로 하는 액상 고무 계열의 표면경화제에 대하여 개시되어 있는데, 단순 살수방법에 비하여 분진 비산방지효과는 좋으나 야적층 표면에서의 결합력이 떨어지며 수분 증발에 따라 균열이 생겨 갈라진다. 따라서, 강한 바람이 불 경우 효과가 떨어지며, 자주 살포해야 하며, 우천시에는 야적층 표면이 씻겨 내려가 야적층이 붕괴되는 등의 단점이 있다.For example, dust scattering prevention by a simple spraying method is simple, but the dust scattering prevention effect is insufficient. On the other hand, Korean Patent Application Publication No. 1999-079852 discloses a liquid rubber-based surface hardener mainly composed of styrene and butadiene, which has a better anti-dust scattering effect than the simple spraying method, but has a low binding force on the surface of the bed layer. As moisture evaporates, cracks develop and crack. Therefore, when the strong wind blows, the effect is reduced, and should be frequently sprayed, there are disadvantages such as the surface of the bed layer is washed down when the rainy weather collapses.

또한, 한국특허출원 공개 제1999-20123호 및 제1997-70157호에서는 시멘트 및 석회석을 주성분으로 한 무기질 도포재에 대하여 개시되어 있는데, 이 무기질 도포재의 경우 분진 비산방지효과는 좋으나 야적층에 도포할 경우 균열 등이 발생하여 우천시 혹은 야적층 일부를 반출할 때 침수되거나 야적층이 붕괴되는 등의 단점이 있다.In addition, Korean Patent Application Publication Nos. 1999-20123 and 1997-70157 disclose inorganic coating materials mainly composed of cement and limestone, which have good anti-dust scattering effect but can be applied to the bed layer. In this case, there are disadvantages such as flooding or collapse of the bed layer during rainy weather or when the part of the bed layer is taken out.

따라서, 본 발명의 목적은, 상술한 종래의 문제점을 해결하여, 야적장의 분말 적재층 위에 도포시 견고한 응고력을 유지하여 분진 비산방지 효과가 탁월할 뿐만 아니라 균열 발생이 없어 우천시에도 침수 방지효과가 우수한, 야적장 분진 비산 방지용 도포재 조성물을 제공하는 것이다.Therefore, the object of the present invention is to solve the above-mentioned problems, and to maintain a solid coagulation force when applied on the powder loading layer of the yard, not only excellent dust scattering effect, but also no cracks, so that the inundation prevention effect even in rainy weather It is to provide an excellent coating material composition for preventing field dust scattering.

상기 목적을 달성하기 위해, 본 발명에서는 폐지 슬러지와 산화칼슘을 주성분으로 하는 경화제를 6/1 ~ 0.5/1 중량비 범위로 포함하는 도포재 조성물이 제공된다.In order to achieve the above object, the present invention provides a coating material composition comprising a waste paper sludge and a curing agent mainly composed of calcium oxide in a 6/1 to 0.5 / 1 weight ratio range.

이하, 본 발명에 대하여 상세히 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

본 발명에 사용되는 폐지 슬러지는 제지 공장에서 폐지를 처리하는 과정에서 폐기물로 얻을 수 있으며, 폐지를 약 5mm 이하로 잘게 잘라 물에 불려 사용할 수도 있다.Waste paper sludge used in the present invention can be obtained as waste in the process of processing waste paper at the paper mill, and can also be used by cutting the waste paper into about 5 mm or less.

또한 본 발명에서 산화칼슘을 주성분으로 하는 경화제는 석회석 등으로부터 제조하거나 광석 혹은 상용 시멘트 등을 이용할 수 있으며, 산화칼슘의 함량이 약 20% 이상인 것이 바람직하다. 이 산화칼슘 성분은 물과 혼합시 응고되는 성질을 갖는다.In addition, in the present invention, the curing agent mainly composed of calcium oxide may be prepared from limestone or the like, ore or commercial cement may be used, and the content of calcium oxide is preferably about 20% or more. This calcium oxide component has a property of solidifying upon mixing with water.

본 발명의 폐지 슬러지와 경화제의 혼합 조성물에 있어서, 폐지 슬러지의 비율이 너무 많으면 도포재의 강도가 떨어지게 되며, 또한 경화제가 너무 많은 경우는 결합력이 떨어져 균열 등이 발생하기 때문에 폐지 슬러지와 경화제의 혼합비율은 6/1 ~ 0.5/1 중량비 범위인 것이 좋다.In the mixed composition of the waste paper sludge and the curing agent of the present invention, when the ratio of waste paper sludge is too large, the strength of the coating material is reduced, and when the amount of the curing agent is too large, the bonding force is reduced, so that a crack or the like occurs, so that the mixing ratio of the waste paper sludge and the curing agent is generated. Is preferably in the range of 6/1 to 0.5 / 1 weight ratio.

이와 같이 본 발명에 따라 폐지 슬러지와 경화제를 포함하는 분진 비산 방지용 도포재는, 폐지 슬러지의 주성분인 펄프 섬유간의 결합력에 의하여 견고한 결합 형태를 유지하게 되며 경화제의 첨가로 인해 딱딱한 표면층을 형성하게 된다. 이에 따라 도포 후 도포막의 강도가 강해지며 균열발생 등이 일어나지 않게 된다.Thus, according to the present invention, the dust scattering prevention coating material including the waste paper sludge and the hardener is maintained by the binding force between the pulp fibers, which is the main component of the waste paper sludge, and forms a hard surface layer due to the addition of the hardener. As a result, the strength of the coating film becomes stronger after application, and cracks do not occur.

본 발명의 도포재 조성물은 야적장 적재층 위에 살포시 상기 폐지 슬러지와 경화제를 소정의 비율로 혼합한 다음, 여기에 물을 10% ~ 90% 혼합하여 슬러리 상태로 하여 분사하게 된다. 살포량은 고형분 기준으로 살포면적 1 m2당 약 150g ~ 800g 정도이면 충분하며, 바람에 의한 분진 비산방지시는 살포량이 적어도 되나 우천시에는 살포량을 늘려 두텁게 도포하는 것이 좋다. 물은 폐지 슬러지와 경화제가 혼합되어 결합력을 나타내도록 해주는 역할을 하는데, 물의 함량이 너무 적은 경우는 도포재를 살포시에 노즐장치 등이 막히는 어려움이 있으며, 물의 함량이 너무 많으면 야적층 등에 살포시 일정 두께로 도포하기 위해서는 많은 양을 뿌려야 하며, 이 경우 물의 함량이 너무 많아 도포재 성분이 야적층과 결합되기 전에 물과 함께 쓸려 내려올 수 있다. 이와 같이 슬러리 형태의 도포재를 야적층 등에 살포하게 되면 물이 증발되면서 폐지슬러지와 경화제의 작용으로 견고한 표면 피막층을 형성하게된다.The coating material composition of the present invention is mixed with the waste paper sludge and the curing agent in a predetermined ratio when spraying on the yard loading layer, and then mixed with 10% to 90% of water to form a slurry. Spraying rate is 1 m based on solid content2About 150g ~ 800g is enough, and the spraying amount is at least when preventing dust scattering by the wind, but in the rain it is better to apply a thicker spraying. Water plays a role of showing the binding force by mixing the waste paper sludge and the hardener. If the content of water is too small, it is difficult to block the nozzle device when spraying the coating material. In order to apply a large amount of water must be sprayed, in which case the content of water is so high that the coating material components can be swept down with water before combining with the bed layer. As such, when the coating material in the form of slurry is sprayed on the bed layer or the like, water is evaporated to form a firm surface coating layer by the action of waste paper sludge and a curing agent.

본 발명에 따른, 폐지슬러지에 산화칼슘을 주성분으로 한 경화제를 혼합한 도포재 조성물은 물 중의 슬러리 형태로 야적층의 표면에 일정 두께로 살포하는 것에 의해 바람에 의해 분진이 비산되는 것을 방지하고, 우천시 야적층이 씻겨 내려감을 방지할 수 있다.The coating material composition which mixed the hardening | curing agent which consists mainly of calcium oxide in the waste paper sludge which concerns on this invention prevents dust to be scattered by wind by spraying it in the form of the slurry in water to the surface of the bed layer to a certain thickness, In rainy weather, the bed can be washed away.

이하, 본 발명의 실시예를 통하여 보다 상세히 설명한다.Hereinafter, the embodiment of the present invention will be described in more detail.

표 1에서 볼 수 있듯이 도포재의 강도는 시간이 흐를수록 높아지며, 약 6일 이후에는 크게 변하지 않는다. 또한 경화제의 비율이 높을수록 강도가 높음을 알 수 있다.As can be seen in Table 1, the strength of the coating material increases with time, and does not change significantly after about 6 days. In addition, it can be seen that the higher the ratio of the curing agent, the higher the strength.

In addition, the performance of the coating material was investigated by measuring the amount of bituminous coal lost by water by spraying water for 1 hour under the condition of rainfall of 1000 mm / hr using a sprinkler on a bed of 1 m above the bed. As a comparative example, a polymer-based surface hardener (Green-666A, Green Chemical) mainly containing about 90 wt% of vinyl acetate and 10 wt% of butyl acrylate was sprayed onto the bed layer to compare the effects thereof, and is shown in Table 2 below.
