Description
본 발명은 비염화물계 융빙제 조성물 및 그의 제조방법에 관한 것으로서, 더욱 상세하게는 부식성이 높은 염소 이온이 전혀 포함되지 않아 구조물과 차량에 대한 부식 피해와 환경에 미치는 피해가 적으면서도 향상된 융빙 능력을 갖는 융빙제 조성물 및 그의 제조방법에 관한 것이다.The present invention relates to a non-chloride-based melter composition and a method for manufacturing the same, more specifically, it does not contain any highly corrosive chlorine ions to improve the melting ability while reducing the damage to the structure and the vehicle and damage to the environment It has a melting agent composition which has, and its manufacturing method.
융빙제란 도로면, 콘크리트 구조물 또는 금속 구조물 등에 융빙/융설 및 동결 방지 목적으로 사용되는 것을 말한다.Melting agent is used for the purpose of melting / melting and freezing of road surfaces, concrete structures or metal structures.
겨울철 눈이 내리거나 비가 온 후에 온도가 급강하되면, 도로가 눈 또는 얼음으로 쌓이는 수가 많다. 원활한 교통 소통이 이루어지게 하기 위하여 도로상의 눈이나 얼음이 신속하고 효과적으로 처리되어야 하는데, 이를 위해 국내에서는 염화칼슘이, 미국·일본 등에서는 소금이 융빙제로서 주로 사용되고 있다. 이들 염화물계 융빙제는 가격이 싸고, 융빙 능력도 우수하지만 금속의 부식을 촉진하는 염소이온을 포함하고 있다. 따라서, 이들 염화물계 융빙제의 지속적인 사용은 교량 및 도로 구조물의 부식을 촉진하여 수명을 단축시키기 때문에 결과적으로 큰 비용 손실을 가져오게 된다. 이들은 주변 환경에도 나쁜 영향을 주어 식물 잎의 황변 또는 고사 등을 일으키기도 한다.If the temperature drops sharply after snowing or raining in winter, the road is often piled up with snow or ice. Snow and ice on the road must be processed quickly and effectively in order to facilitate smooth traffic communication. For this purpose, calcium chloride is used in Korea, and salt is used as a melting agent in the United States and Japan. These chloride-based melters contain chlorine ions that are inexpensive and have excellent melting ability but promote corrosion of metals. Thus, the continued use of these chloride-based ice melts promotes corrosion of bridges and road structures and shortens their lifespan, resulting in significant cost loss. They also adversely affect the environment, causing yellowing or death of plant leaves.
현재 비행기나 공항 활주로와 같은 특수 상황의 경우에는 요소, 프로필렌 글리콜 등의 비염화물계 융빙제가 사용되고 있다. 요소는 부식성이 작으나 -4℃ 이상에서만 효과적인 융빙이 가능하고, 또한 사용무게당 빙점 강하 능력도 작아서 다량 살포해야 하며, 과량 사용시에는 식물 잎의 황변 현상도 일으킨다. 프로필렌 글리콜은 부식성이 없고 저독성이나, 윤활성이 있어서 미끄럼 저항을 감소시키며, 생화학적 산소 요구량(BOD, Biochemical Oxygen Demand)이 대단히 크기 때문에 생분해가 잘 되지 않는다.Currently, in special situations such as airplanes and airport runways, non-chlorinated melters such as urea and propylene glycol are used. Urea is less corrosive but can be effectively melted at temperatures above -4 ° C, and also has a low freezing point drop per weight. Therefore, urea must be sprayed in large quantities. Propylene glycol is not corrosive and low toxicity, but lubricity reduces slip resistance and is not biodegradable due to its very high Biochemical Oxygen Demand (BOD).
따라서, 상대적으로 낮은 온도에서도 생분해가 되고, 부식성이 적으며, 콘크리트와 환경에 대한 나쁜 영향도 없되 융빙 능력은 염화물계와 비슷하거나 더 우수한 대체 융빙제를 개발하는 것이 필요하다.Therefore, it is necessary to develop alternative melters that are biodegradable, less corrosive, and have no adverse effects on concrete and the environment, but at a relatively low temperature but have similar or better melting ability than chloride systems.
대체 융빙제를 개발하는 방향은 크게 염화칼슘이나 소금과 같은 염화물계 융빙제에 부식을 방지하는 방청제를 첨가하는 방법과, 염소이온이 포함되지 않은 비염화물계 융빙제를 개발하는 방법의 두 가지 방향으로 나누어 볼 수 있다.There are two main directions for developing alternative melters: adding corrosion preventives to chloride-based melters such as calcium chloride and salt, and developing non-chlorinated melters that do not contain chlorine ions. You can share it.
첫 번째 개발 방향은 USP 3935125, USP 4613450, USP 5531931, USP 5595679 등에서 보는 바와 같이 염화물계 융빙제에 소량의 아민인산염, 불소인산염, 희토류 금속염, 알카리금속 실리케이트 또는 이들의 혼합물을 첨가하여 사용하는 것이다. 이렇게 융빙제 속에 포함된 방청제는 포함된 방청제의 양, 온도 및 산소의 양에 따라 방청 효과가 좌우된다고 한다. 그러나, 그 방청 효과에 대해서는 많은 논란이 있다. 즉, 방청제가 콘크리트와 반응을 하여 고정되므로 콘크리트 속으로 침투하지 못하기 때문에 철근 부식을 방지하는 역할을 하지 못한다는 보고가 있으며, 방청 효과가 있다고 하더라도 비염화물계 유기산염보다는 못하다는 결과도 보고되고 있다.The first direction of development is to use a small amount of amine phosphate, fluorine phosphate, rare earth metal salts, alkali metal silicates or mixtures thereof in chloride based melters as shown in USP 3935125, USP 4613450, USP 5531931, USP 5595679 and the like. The rust preventive agent contained in the melting agent depends on the amount of the rust preventive agent, the temperature and the amount of oxygen contained. However, there is much debate about the rust prevention effect. In other words, since the rust inhibitor reacts with concrete and is fixed, it does not penetrate into the concrete and thus does not play a role in preventing corrosion of the reinforcing bar. have.
두 번째 개발 방향에 의한 비염화물계 융빙제로는 CMA(칼슘 마그네슘 아세테이트 :Calcium Magnesium Acetate), 초산 칼륨을 비롯한 초산염 계열과, 포름산 나트륨 등이 있다. CMA는 미국에서 집중적으로 개발되었는데, 환경친화적이고 부식성이 낮은 장점이 있는 반면에, 밀도가 낮아 가루가 많이 날리고, pH가 9이상인 경우에도 가수분해되어 몸에 해로운 초산 증기가 만들어지는 문제점이 있으며, 융빙 속도면에서 염화칼슘 뿐만 아니라 소금보다도 느리고, 가격도 훨씬 비싸며, 동일한 융빙 효과를 나타내기 위해서는 더 많은 양을 뿌려야만 하는 단점이 있다. 또한, CMA는 흡습성도 있어서, 예를 들자면 낮 동안 보통은 건조해야할 지역에 이를 뿌림으로 해서 젖은 상태로 남아있게 되어 늦은 오후나 이른 아침에 얼음이 생길 위험이 있고, 케이크화 현상도 일어나는 등 많은 단점을 보이고 있다. 이러한, CMA는 초산과 돌로마이트로부터 만들어지는데(USP 4636467), 초산의 가격이 고가이므로 USP 4664832, USP 5498362, WO 97/40119 에 개시된 바와 같이 원료인 초산을 치즈유장(cheese whey)이나 생폐기물(biomass)로부터 발효나 고온고압하에서 알카리와의 반응을 통하여 얻어내려는 노력이 많이 기울여져 왔다. 그러나, 이러한 방법으로 생성되는 유기산은 초산 뿐만 아니라 이보다 더 분자량이 큰 여러 종류의 유기산을 포함하게 되어, 결과적으로 융빙제의 융빙 능력을 떨어뜨리는 문제점을 나타낸다. 초산칼륨은 CMA와 마찬가지로 밀도가 낮아서 가루가 날리고 가수분해되어 초산이 생성되는 등의 단점은 있으나, 공융점이 대단히 낮아서 -26℃ 정도의 낮은 온도에서도 효과를 발휘하므로 주로 액체 상태로 사용되고 있다. USP 5435930은 비행기 표면에 사용할 수 있는 초산칼륨이 포함된 용액의 성분을 밝히고 있다. 팔머(Palmer)(TRL 1127, 1987)에 의하면, 포름산나트륨은 CMA와 같은 가루날림 문제가 적고, 부식성이 낮아서 콘크리트의 파열을 유발하지 않는 유망한 대체 융빙제이다. 그러나, 이것도 소금과 마찬가지로 용해시 흡열을 하며, 소금보다 융빙 능력이 떨어지고, 가격은 소금보다 훨씬 비싸다는 단점을 가지고 있다.Non-chlorinated melting agents according to the second development direction include CMA (Calcium Magnesium Acetate), acetate series including potassium acetate, and sodium formate. CMA has been developed intensively in the United States, while being environmentally friendly and low corrosive, while low density, a lot of powder is blown, and even when the pH is above 9, hydrolysis of acetic acid vapor is made. In terms of melting speed, it is slower than salt as well as calcium chloride, much more expensive, and has to be sprayed in order to achieve the same melting effect. In addition, CMA is also hygroscopic, which means that it can be left wet during the day, for example by sprinkling it on areas that should be dry, and there is a risk of ice in the late afternoon or early morning, and cake formation. Is showing. These CMAs are made from acetic acid and dolomite (USP 4636467). Since the price of acetic acid is high, acetic acid, as disclosed in USP 4664832, USP 5498362, WO 97/40119, is used as cheese whey or biomass. From the fermentation or reaction with alkali under high temperature and high pressure, much effort has been made. However, the organic acid produced by this method includes not only acetic acid but also various kinds of organic acids having a higher molecular weight than this, resulting in a problem of lowering the melting ability of the melting agent. Potassium acetate, like CMA, has a low density, such as powder flying and hydrolysis to produce acetic acid. However, since the eutectic point is very low, it is mainly used in a liquid state because it exhibits an effect even at a low temperature of about -26 ° C. USP 5435930 identifies the components of solutions containing potassium acetate that can be used on airplane surfaces. According to Palmer (TRL 1127, 1987), sodium formate is a promising alternative melter that has less scouring problems such as CMA and is less corrosive and does not cause concrete to rupture. However, like salt, it absorbs heat when dissolving, and has a disadvantage in that melting ability is lower than salt and price is much higher than salt.
본 발명은 상기와 같은 종래의 융빙제들이 가지고 있는 문제점들을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 염소이온을 전혀 포함하지 않아 부식성도 낮고, 콘크리트의 파열도 일으키지 않으며, 환경 친화적이고, 가루날림 문제도 없으며, 빙점강하 특성이 좋아서 융빙 능력이 염화칼슘이나 소금보다 우수한 새로운 비염화물계 융빙제 조성물 및 그의 제조방법을 제공하는 것이다.The present invention has been made to solve the problems of the conventional melter as described above, the object of the present invention does not contain any chlorine ions, low corrosiveness, does not cause concrete rupture, environmentally friendly, powder There is no flying problem, and the freezing point drop property is good to provide a new non-chloride-based melting agent composition and a method for producing the same excellent melting ability than calcium chloride or salt.
상기한 목적을 달성하기 위하여, 본 발명은 초산염, 탄산염 및 포름산염이 혼합된 복합염을 포함하는 융빙제 조성물 및 그의 제조방법을 제공한다.In order to achieve the above object, the present invention provides a melter composition and a method for producing the same comprising a composite salt mixed with acetate, carbonate and formate.
바람직하게, 상기 융빙제 조성물은 초산염 20∼80중량부, 탄산염 3∼20중량부 및 포름산염 20∼80중량부로 구성된 복합염을 포함한다.Preferably, the melter composition comprises a complex salt consisting of 20 to 80 parts by weight of acetate, 3 to 20 parts by weight of carbonate and 20 to 80 parts by weight of formate.
본 발명에 따른 융빙제 조성물은Melting agent composition according to the present invention
염기와 해당 유기산들(즉, 초산, 탄산 및 포름산) 간의 중화반응 후 건조·분쇄를 통하거나, 각 유기산 염들을 물리적으로 분쇄·혼합시켜서 분말 형태의 복합염을 만들고;Neutralization between the base and the corresponding organic acids (ie, acetic acid, carbonic acid, and formic acid), followed by drying and grinding, or physically pulverizing and mixing the respective organic acid salts to form a complex salt in powder form;
이를 결합제(binder)를 이용하여 조립, 건조 가공하여 원하는 크기, 예를 들어, 0.05∼20mm, 바람직하게 0.1∼10 mm 크기의 입자로 구성되도록 함에 의해 제조할 수 있다.It can be prepared by assembling and drying using a binder so as to be composed of particles of a desired size, for example, 0.05-20 mm, preferably 0.1-10 mm.
본 발명에 사용되는 복합염의 성분 중에서 초산염은 지속성 있는 융빙을 가능하게 해주고; 탄산염은 용해열이 커서 융빙 속도를 빠르게 하며, 밀도가 높아서 침투능력이 향상되게 해주고; 포름산염은 단위 중량당 융빙량이 높은 장점이 있다. 따라서, 이 염들을 적절한 비율로 혼합하게 되면 각 개별적인 염들보다 확연히 향상된 융빙 능력을 보이게 되는 바, 향상된 융빙 능력을 보이기 위한 적정 혼합 비율은 초산염 20∼80중량부, 탄산염 3∼20중량부 및 포름산염 20∼80중량부 이다.Among the components of the complex salts used in the present invention, acetate allows for sustained melting; Carbonates have a large heat of dissolution, which speeds up the melting speed, and a high density allows the penetration ability to be improved; Formate has the advantage of high melting amount per unit weight. Therefore, when the salts are mixed in an appropriate ratio, the melting capacity is significantly improved than that of the individual salts. The proper mixing ratio for the improved melting capacity is 20 to 80 parts by weight of acetate, 3 to 20 parts by weight of carbonate, and formate. 20 to 80 parts by weight.
본 발명에 사용되는 염들을 구성하는 양이온들로는 나트륨, 칼륨, 칼슘, 마그네슘, 리튬, 암모늄 이온 등이 포함된다. 따라서, 각 구성 염들중 초산염으로는 초산나트륨, 초산칼륨, 초산칼슘, 초산마그네슘, 초산리튬, 초산암모늄 등이 포함되고, 탄산염으로는 탄산나트륨, 탄산칼륨, 탄산칼슘, 탄산마그네슘, 탄산리튬, 탄산암모늄 등이 포함되며, 포름산염으로는 포름산나트륨, 포름산칼륨, 포름산칼슘, 포름산마그네슘, 포름산리튬, 포름산암모늄 등이 포함된다.Cations constituting the salts used in the present invention include sodium, potassium, calcium, magnesium, lithium, ammonium ions and the like. Accordingly, among the constituent salts, acetates include sodium acetate, potassium acetate, calcium acetate, magnesium acetate, lithium acetate, ammonium acetate, and the like, and carbonates include sodium carbonate, potassium carbonate, calcium carbonate, magnesium carbonate, lithium carbonate, and ammonium carbonate. And the like, sodium formate, potassium formate, calcium formate, magnesium formate, lithium formate, ammonium formate and the like.
본 발명에 사용되는 복합염을 중화반응 후 건조·분쇄를 하는 화학적 방법으로 제조하는 경우에 사용하는 염기로는, 예를 들어, 수산화칼슘, 수산화칼륨, 수산화나트륨, 수산화마그네슘, 수산화리튬, 암모니아수, 탄산칼슘, 탄산칼륨, 탄산나트륨, 탄산마그네슘, 탄산리튬, 탄산암모늄 등을 사용할 수 있다.Examples of the base used in the preparation of the complex salt used in the present invention by a chemical method of drying and grinding after neutralization include, for example, calcium hydroxide, potassium hydroxide, sodium hydroxide, magnesium hydroxide, lithium hydroxide, ammonia water, and carbonic acid. Calcium, potassium carbonate, sodium carbonate, magnesium carbonate, lithium carbonate, ammonium carbonate and the like can be used.
복합염을 조립할 때 사용하는 결합제(binder)로는, 예를 들어, 물, 규산나트륨(sodium silicate), 초산칼륨(potassium acetate), 전분(starch), 벤토나이트 (bentonite), 글루코스(glucose), 슈크로스(sucrose), 덱스트린(dextrin), 리그노설포네이트(lignosulfonate), 당밀(molasses), 알기네이트(alginate) 또는 이들의 혼합물 등을 사용할 수 있다. 이들 결합제 중에서 조립공정 후에 건조과정에서 증발되어서 최종 생산된 융빙제 조성물에 영향을 주지 않는 물이 가장 바람직하다. 결합제의 사용량은 복합염 100중량부를 기준으로 물은 2∼30 중량부, 물외의 결합제는 2∼10 중량부, 총결합제는 2∼30 중량부의 양으로 사용한다.Examples of binders used to assemble the complex salts include water, sodium silicate, potassium acetate, starch, bentonite, glucose, and sucrose. (sucrose), dextrin (dextrin), lignosulfonate (lignosulfonate), molasses (molasses), alginate (alginate) or mixtures thereof and the like can be used. Of these binders, water that is evaporated during drying after the granulation process and does not affect the final produced melt composition is most preferred. The binder is used in an amount of 2 to 30 parts by weight of water, 2 to 10 parts by weight of the binder other than water, and 2 to 30 parts by weight of the total binder, based on 100 parts by weight of the composite salt.
복합염을 조립할 때, 반응 조건에 따라 입경과 분포가 다르게 나타나므로, 조립시간, 조립시 회전수, 결합제(binder)의 양 등을 조절하여 융빙제로 사용하기에 적절한 입경(0.05∼20 mm, 바람직하게 0.1∼10 mm)의 혼합염을 제조할 수 있다. 0.1∼10 mm 사이의 입경이 바람직한데, 이 범위의 입경의 경우 가루날림의 문제가 발생하지 않고, 융빙효과 또한 우수하기 때문이다. 조립시간은 약 5∼15분이 바람직하며, 조립시 회전수는 250∼550 rpm 범위가 바람직하다.When assembling the composite salt, the particle size and distribution are different depending on the reaction conditions. Therefore, the particle size suitable for use as a melting agent is controlled by adjusting the assembly time, the number of rotations during the assembly, the amount of binder, and the like (0.05 to 20 mm, preferably 0.1 to 10 mm) can be prepared. Particle diameters between 0.1 and 10 mm are preferred, because particle size ranges in this range do not cause dusting and have excellent melting effects. The assembly time is preferably about 5 to 15 minutes, and the rotation speed during assembly is preferably in the range of 250 to 550 rpm.
본 발명에 따라 제조된 융빙제 조성물은 -25℃∼-51℃ 범위의 공융점을 나타내므로 소금이 작용하는 온도보다 더 낮은 온도에서도 효과적이다.Melting agent compositions prepared according to the present invention exhibit an eutectic point in the range of -25 ° C to -51 ° C and are therefore effective even at temperatures lower than the temperature at which salt acts.
이하에서 본 발명을 실시예에 의해 더욱 상세하게 설명하나, 본 발명의 범위가 하기 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples, but the scope of the present invention is not limited by the following Examples.
