Description
본 발명은 폐석회 또는 폐조개류를 이용한 제설제 조성물에 관한 것이다. 더욱 구체적으로는 폐석회 또는 폐조개류의 분쇄물에 당량의 초산(CH3COOH)을 가하고 반응시켜 얻은 초산칼슘(calcium acetate)을 주성분으로 하는 알칼리 초산염 100 중량부; 알긴산 소다(Sodium Alginate) 0.01∼2 중량부; 및 망초(Na2SO4·10H2O) 1∼20 중량부로 이루어진 제설제 조성물에 관한 것이다.The present invention relates to a snow removing composition using waste lime or shellfish. More specifically, 100 parts by weight of alkali acetate mainly composed of calcium acetate obtained by adding an equivalent amount of acetic acid (CH 3 COOH) to a pulverized product of waste lime or waste clam; 0.01-2 parts by weight of sodium alginate; And 1 to 20 parts by weight of manganese (Na 2 SO 4 · 10H 2 O).
동절기에는 지역에 따라 많은 눈이 내리는데, 많은 적설량은 교통 및 통신을 마비시킬 뿐만 아니라 건축물의 붕괴 위험까지도 가져올 수 있으므로, 겨울철 사고방지를 위해서는 신속하고 적절한 제설작업이 요구된다.In winter, there is a lot of snow depending on the region, and the amount of snow can not only paralyze traffic and communication, but also bring about the risk of collapse of the building.
염화칼슘이나 염화나트륨은 물에 쉽게 용해되고 물의 흡수능력이 있을 뿐만 아니라 물과 반응하여 어느 정도의 열을 발생하여 눈을 녹이게 되므로, 겨울철 제설·제빙에는 염화칼슘(CaCl2)이나 염화나트륨(NaCl2)의 단일화합물 또는 혼합물이 일반적으로 많이 사용되고 있다. 그러나, 이러한 염화칼슘(CaCl2)이나 염화나트륨 (NaCl2)은 그 자체로서의 제설작용이 미흡할 뿐만 아니라, 염화물로서 도로 등에 산포될 경우 이온화되어 도로상에 다량의 염소이온이 존재하게 되고 이것이 금속이온 특히 철(Fe)과 결합하여 염화제이철(FeCl3)을 형성하여 철을 부식시키게 되므로 교량 등 철을 함유한 콘크리트 구조물의 붕괴원인 및 자동차의 부식원인이 된다. 따라서, 선진국에서는 제설제를 뿌린 후 반드시 세차를 하도록 홍보하고 있는 실정이다. 이러한 문제점 때문에 염화물을 주성분으로 하는 기존의 제설제를 대체할 수 있는 새로운 제설제로, 제설·제빙효과가 뛰어나면서도 염소이온을 발생시키지 않고 따라서 철골구조물 및 차량을 부식시킬 염려가 없는 제설제가 요구된다.Calcium chloride and sodium chloride are easily soluble in water, absorb water, and react with water to generate some heat to melt snow. Therefore, during winter snow removal and deicing, calcium chloride (CaCl 2 ) or sodium chloride (NaCl 2 ) Single compounds or mixtures are commonly used. However, such calcium chloride (CaCl 2 ) and sodium chloride (NaCl 2 ) not only have insufficient snow removing action on their own but also become ionized when they are scattered on the road as chlorides, so that a large amount of chlorine ions are present on the road. It combines with iron (Fe) to form ferric chloride (FeCl 3 ) to corrode iron, causing the collapse of concrete structures containing iron such as bridges and corrosion of automobiles. Therefore, the developed countries are promoting to wash the car after the snow removal. Due to these problems, a new snow removing agent which can replace the existing snow removing agent mainly composed of chloride, is required for a snow removing agent that has excellent snow removal and ice making effect and does not generate chlorine ions and thus does not cause corrosion of steel structures and vehicles.
이에 본 발명자는 기존의 염화칼슘 등을 대체할 수 있는 새로운 제설제로서 한국특허 제195385호 '제설제빙제 조성물 및 이의 제조방법과 이를 사용한 제설제빙방법'을 개발한 바 있다. 상기 특허에 개시된 제설제빙제 조성물은 산화칼슘 (CaO) 30∼100 중량부, 염화마그네슘(MgCl2) 5∼30 중량부, 염화칼슘(CaCl2) 3∼10 중량부 및 알긴산소다(Sodium Alginate) 0.2∼2 중량부로 이루어진 것으로, 눈(얼음)과 접촉시 순간적으로 많은 양의 열을 발생하므로 기존의 염화칼슘에 비해 제설효과가 월등하게 뛰어나고 신속하나, 첫째, 공기중의 수분을 흡수하여 반응하기 때문에 보관이 어렵고, 둘째, 염화물인 염화마그네슘과 소량의 염화칼슘을 포함하므로 염화칼슘에 비해 훨씬 적은 양(약 10분의 1)이기는 하나 산포후 염소이온이 잔류하며, 셋째, 반응이 지속적이지 않다는 문제점이 있었다.Accordingly, the present inventors have developed Korean Patent No. 195385, 'Deicing Deicing Agent Composition and Manufacturing Method Thereof and De-icing Method Using the Same', as a new snow removing agent which can replace the existing calcium chloride. The deicing snow composition disclosed in the patent is 30 to 100 parts by weight of calcium oxide (CaO), 5 to 30 parts by weight of magnesium chloride (MgCl 2 ), 3 to 10 parts by weight of calcium chloride (CaCl 2 ) and sodium alginate (Sodium Alginate) 0.2 It is composed of ˜2 parts by weight. Since it generates a large amount of heat instantaneously when it comes in contact with snow (ice), the snow removal effect is superior and rapid compared to conventional calcium chloride, but first, it is stored because it absorbs and reacts with air This is difficult, and secondly, since it contains a magnesium chloride and a small amount of chloride, it is a much smaller amount (about a tenth) than calcium chloride, but chlorine ions remain after dispersion, and third, there is a problem that the reaction is not continuous.
한편, 버려지는 폐석회 및 폐조개류, 폐굴껍데기 등은 환경보전 차원에서 문제가 되고 있으나, 이를 이용할 특별한 방법이 없는 상황에서 처리비용만 발생되므로 그대로 방치되고 있는 실정이다. 따라서, 이러한 폐기물의 활용방법 또한 환경보호 차원에서 요구되고 있다고 할 수 있다.On the other hand, discarded waste lime, waste shellfish, waste oyster shell is a problem in terms of environmental preservation, but the situation is left as it is because the processing costs are generated in the absence of a special way to use it. Therefore, it can be said that the utilization method of such waste is also required from the viewpoint of environmental protection.
이에 본 발명자는 폐조개류 등의 폐기물을 이용하여 환경보전에 이바지하는 한편, 이를 이용한 제설제로서 기존의 제설제와 비교하여 제설·제빙효과에 있어서 동등하거나 보다 우수하면서도 보관이 용이하고 산포후 염소이온이 잔류하지 않아 건축물이나 차량에 대한 피해가 전혀 없는 제설제를 개발하고자 연구하게 되었다.Accordingly, the present inventors contribute to environmental preservation using waste such as waste shellfish, and are equivalent to or better in snow removal and deicing effect as compared with the existing snow removing agent as a snow removing agent using the same, and is easy to store, and chlorine ion after scattering. Because of the absence of this residue, the study was carried out to develop a snow removing agent that has no damage to buildings or vehicles.
본 발명은 상기한 문제점을 감안하여 안출된 것으로, 폐석회 및 폐조개류 등의 폐기물을 이용하여 제설제를 제조함으로써 제설효과가 우수한 제설제를 제공하는 동시에 방치되는 폐기물을 활용하여 환경보전에 이바지하는 것을 목적으로 한다.The present invention has been made in view of the above-described problems, by using a waste such as waste lime and waste shells to provide a snow removing agent having a high snow removal effect while at the same time utilizing the waste that is left to contribute to environmental conservation For the purpose of
또한, 본 발명은 제설·제빙효과에 있어서 기존의 제설제와 동등하거나 보다 우수하면서도 보관이 용이하고, 산포후 염소이온이 잔류하지 않아 건축물이나 차량에 대해 전혀 피해가 없으며, 열량발생이 지속적이어서 특히 계속적으로 눈이 내리는 경우에도 효과가 있는 제설제를 제공하는 것을 목적으로 한다.In addition, the present invention is equivalent to or better than the existing snow removing agent in the snowmaking and ice making effect, and is easy to store, there is no damage to the building or the vehicle since there is no chlorine ion remaining after scattering, and calorie generation is particularly continued. It is an object of the present invention to provide a snow removing agent that is effective even when it is snowing continuously.
상기와 같은 목적을 달성하기 위하여, 본 발명에서는 폐석회 또는 폐조개류의 분쇄물에 당량의 초산(CH3COOH)을 가하고 반응시켜 얻은 초산칼슘(calcium acetate)을 주성분으로 하는 알칼리 초산염 100 중량부; 알긴산 소다(Sodium Alginate) 0.01∼2 중량부; 및 망초(Na2SO4·10H2O) 1∼20 중량부로 이루어진 제설제 조성물을 제공한다.또한, 본 발명에서는 상기 제설제 조성물 100 중량부에 모래 또는 저가의 무기산화물 50∼150 중량부를 가하여 교반, 코팅시킨 고상의 제설제를 제공한다.상기 제설제 조성물에는 바람직하게는 초산칼슘을 주성분으로 하는 알칼리 초산염 100 중량부에 대하여 전분 0.1∼0.2 중량부 및 안료 0.01∼0.5 중량부가 포함된다.In order to achieve the above object, the present invention is 100 parts by weight of an alkali acetate containing calcium acetate (calcium acetate) as a main component obtained by adding an equivalent amount of acetic acid (CH 3 COOH) to the crushed waste lime or shellfish; 0.01-2 parts by weight of sodium alginate; And 1 to 20 parts by weight of manganese (Na 2 SO 4 · 10H 2 O). In the present invention, 50 to 150 parts by weight of sand or inexpensive inorganic oxide is added to 100 parts of the snow removal composition. A solid snow removing agent coated with a stirring is provided. The snow removing agent composition preferably contains 0.1 to 0.2 parts by weight of starch and 0.01 to 0.5 parts by weight of pigment based on 100 parts by weight of an alkali acetate containing calcium acetate as a main component.
이하, 본 발명에 따른 제설제의 제조방법을 공정별로 상세히 설명한다.Hereinafter, a method of manufacturing a snow removing agent according to the present invention will be described in detail for each step.
공정 ⅠProcess Ⅰ
수집된 폐석회 및 폐조개류를 분쇄한 후 물을 가하고 가열한다.The collected waste lime and shellfish are ground and then heated and heated.
폐석회 및 폐조개류는 폐기물로 버려지는 일반적인 폐석회와 해안가에 버려지는 폐조개류, 폐굴껍데기 등을 수집하여 사용한다.Waste lime and shellfish collect and use the general waste lime that is thrown away as waste, the shellfish that are discarded on the shore, and the shells of oysters.
공정 ⅡProcess II
공정 Ⅰ에서 얻은 폐석회 및 폐조개류의 가열된 분쇄혼합물에 당량의 초산(CH3COOH)을 가해 반응시킨다.An equivalent of acetic acid (CH 3 COOH) is added to the heated milled mixture of waste lime and waste clam obtained in Step I to react.
폐석회 및 폐조개류는 다량의 칼슘을 포함하고 기타 마그네슘, 나트륨, 칼륨 등과 같은 알칼리 금속 및 미량의 무기물 및 유기물을 포함한다. 따라서 이들의 분쇄물을 용해시켜 초산과 반응시키면 초산칼슘을 주성분으로 하는 알칼리 초산염을 형성하게 된다. 이렇게 형성된 초산칼슘을 주성분으로 하는 알칼리 초산염은 물(눈)과 반응하여 열을 발생시키고 물을 흡수하기도 하여 제설작용을 하게 된다.Waste lime and shellfish contain large amounts of calcium and other alkali metals such as magnesium, sodium, potassium and the like and trace minerals and organics. Therefore, when these pulverized products are dissolved and reacted with acetic acid, an alkali acetate containing calcium acetate as a main component is formed. Alkaline acetate, which is composed of calcium acetate as a main component, reacts with water (eye) to generate heat and absorb water.
공정 ⅢProcess III
공정 Ⅱ에서 얻은 알칼리 초산염 100 중량부에 알긴산 소다(Sodium Alginate) 0.01∼2 중량부 및 망초(Na2SO4·10H2O) 1∼20 중량부를 가하고 균일하게 교반하여 본 발명에 따른 제설제 조성물을 얻는다.0.01 to 2 parts by weight of sodium alginate and 1 to 20 parts by weight of sodium forage (Na 2 SO 4 · 10H 2 O) are added to 100 parts by weight of the alkali acetate obtained in step II, and the mixture is stirred uniformly according to the present invention. Get
알긴산 소다 및 망초는 초산염을 포함한 다른 구성성분과 상호 유기적으로 작용하여 제설효과를 상승시키게 된다. 특히 알긴산 소다는 다당류염으로서 물에 서서히 녹아 고점성의 액체를 형성하게 되므로, 본 발명에 따른 제설제가 산포되어 일단 눈이 녹게 되면 기온이 다시 하강하여 얼음이 얼게 되더라도 함유된 알긴산 소다에 의해 단단한 얼음결정을 만들지 못하고 푸석푸석한 상태가 되게 된다.Soda alginate and forget-me-not interact with other constituents, including acetate, to increase the snow removal effect. In particular, alginic acid soda is a polysaccharide salt that is slowly dissolved in water to form a highly viscous liquid.So, once the snow remover is dispersed and the snow melts, the temperature is lowered again so that the ice is frozen even if the ice is frozen. Could not make a crumbly state.
망초(Na2SO4·10H2O)는 열저장 작용이 있어 본 발명에 따른 제설제가 눈과 접촉하여 발생시키는 열을 장시간 보존하는 역할을 하는 동시에 제설후 토양을 단단하게 하는 역할을 하게 된다. 따라서, 본 발명에 따른 제설제는 기존의 제설제와 달리 열량발생이 지속적이어서 몇 시간씩 계속적으로 눈이 내릴 경우에도 효과적이다.Forget-me-not (Na 2 SO 4 · 10H 2 O) has a heat storage action and serves to preserve the heat generated by the snow removal agent according to the present invention in contact with the eyes for a long time and at the same time serves to harden the soil after snow removal. Therefore, the snow removal agent according to the present invention is effective even when the snow continuously falling for several hours because the calorie generation is continuous unlike the conventional snow removal agent.
또한, 바람직하게는 공정 Ⅱ에서 얻은 알칼리 초산염 100 중량부에 대해 전분 0.1∼0.2 중량부 및 안료 0.01∼0.5 중량부를 가한다. 전분은 응집제의 역할을 하게 되므로 다른 성분들과 상호 작용하여 제설작용을 증강시키게 된다. 또한 안료를 가해 색상을 부여하면 식별이 용이해져 제설작업의 관리, 감독이 용이해진다. 안료로는 활성탄이나 기타 인체 및 환경에 무해한 기존의 안료가 사용될 수 있다.Further, preferably, 0.1 to 0.2 parts by weight of starch and 0.01 to 0.5 parts by weight of pigment are added to 100 parts by weight of the alkali acetate obtained in step II. Starch acts as a flocculant and thus interacts with other ingredients to enhance snow removal. In addition, the addition of pigments to give color facilitates identification and management and supervision of snow removal operations. As the pigment, activated carbon or other conventional pigments that are harmless to humans and the environment may be used.
공정 ⅣProcess IV
공정 Ⅲ에서 얻은 제설제 조성물 원액 100 중량부에 모래 또는 저가의 무기산화물 50∼150 중량부를 가하고 균일하게 교반하여, 모래 또는 무기산화물에 제설제 조성물 원액이 코팅된 고상의 제설제를 얻는다. 이렇게 모래 등에 본 발명에 따른 제설제 조성물을 코팅시키면 제설제의 비표면적이 증대되고 모래 등과의 상호작용으로 제설능력이 향상되므로, 저렴한 가격으로 제설효과가 우수한 제설제를 얻을 수 있게 된다.50 to 150 parts by weight of sand or an inexpensive inorganic oxide is added to 100 parts by weight of the stock solution of the snow removal composition obtained in step III and stirred uniformly to obtain a solid snow removal agent coated with the snow removal composition of the snow removal composition. When the snow removal composition according to the present invention is coated on sand or the like, the specific surface area of the snow removal agent is increased, and the snow removal ability is improved by interaction with sand. Thus, it is possible to obtain a snow removal excellent snow removal effect at a low price.
또한, 본 발명의 제설제는 폐석회 및 폐조개류 대신에 수산화칼슘(Ca(OH)2), 산화칼슘(CaO) 및 수산화나트륨(NaOH) 등을 사용하여 초산과 반응시켜 제조할 수도 있다. 이렇게 제품화된 원료를 사용하여 본 발명의 제설제를 제조할 경우 제조공정은 보다 간단해지나, 폐기물의 활용과 비용절감 측면에서 볼 때 폐석회 및 폐조개류를 수거하여 사용하는 것이 바람직하다.In addition, the snow removing agent of the present invention may be prepared by reacting with acetic acid using calcium hydroxide (Ca (OH) 2 ), calcium oxide (CaO), sodium hydroxide (NaOH), or the like instead of waste lime and shellfish. When the snow removing agent of the present invention is manufactured using the raw material thus manufactured, the manufacturing process becomes simpler, but it is preferable to collect and use waste lime and shellfish in view of waste utilization and cost reduction.
