Description
본 발명은 보일러용 난방수에 관한 것으로, 주성분이 정제 글리콜에 방청제로 사용되는 3인산소다와 안식향소다를 첨가하고, 초기 열전도를 촉진시키기 위한 메칠알콜과 열전도율을 향상시키는 나트륨(NaCl)을 적당량 첨가한 후, 여기에 순수(純水)와 pH를 조절하기 위해 붕산을 첨가하여 열전도율이 뛰어나면서도 난방수 순환 파이프에 스케일이 생성되지 않으며, 동절기 미사용 시 배관이 동파되는 것을 방지한 보일러용 난방수에 관한 것으로, 동절기에 동파를 방지하면서도 열전도율이 뛰어나고 보일러의 내연기관과 배관 등에 생성되는 스케일 등을 방지하여 난방수의 순환을 원활히 하며, 특히 초기 열전도율이 뛰어나 열효율이 높은 것을 특징으로 하고 보다 저렴한 보일러용 난방수를 일반 소비자들에게 제공하는 것을 목적으로 하였다.The present invention relates to heating water for boilers, the main components of which are added trisodium phosphate and benzoic acid, which are used as rust preventives, and methyl alcohol and sodium (NaCl) to improve thermal conductivity. After the addition of pure water and boric acid to adjust the pH, the thermal conductivity is excellent and the scale is not generated in the heating water circulation pipe. In this regard, it is excellent in thermal conductivity while preventing freezing in winter, and prevents scales generated in internal combustion engines and pipes of boilers, thereby circulating heating water smoothly. Especially, it is characterized by high initial thermal conductivity and high thermal efficiency. The aim was to provide heating water to the average consumer.
일반적으로 보일러용 난방수로 물을 사용하고 있는바, 이는 열전도율이 떨어져서 보일러에서 가열된 열량을 초기에 빠르게 방바닥으로 전달하지 못하는 것은 물론, 보일러에서 가열되는 열량의 전달이 완벽하지 못하여 실제로 난방에 사용되는 열효율이 떨어졌으며, 오랜 기간 사용하면 보일러의 가열파이프와 기타 연결구 등을 부식시켜 스케일과 물때로 인한 부식의 발생으로 인해 순환계통의 정지와 막힘의 문제를 야기시킬 뿐 아니라 보일러의 수명을 단축시키는 등 많은 문제점이 있었으며, 동절기에 보일러를 가동하지 않으면 쉽게 얼어서 동파되므로 경제적 손실과 불편을 가져오는 문제점이 발생되고 있다.In general, water is used as the heating water for the boiler, which has a low thermal conductivity, which does not quickly transfer heat from the boiler to the floor in the early stage, and is not used to transfer heat from the boiler. Its thermal efficiency is low, and if it is used for a long time, it can corrode the heating pipes and other connections of the boiler, causing corrosion of scale and scale, causing problems of stopping the circulation system and clogging as well as shortening boiler life. There have been many problems, such as freezing and freezing if you do not operate the boiler in winter, causing economic loss and inconvenience.
상기와 같은 문제점들을 해결하기 위하여 에틸렌 글리콜과 물을 주성분으로 한 "열매체용 액체 조성물"이 대한민국공개특허 제 554호(1988. 3. 26), 대한민국공개특허 제 4064호(1988. 6. 12)로 공개되었으나 열매체용 액체 조성물에 함유되어 있는 석면과 유화제가 결합하여 보일러의 내연기관 및 배관에 부착되어 스케일이 형성될 뿐만 아니라 보일러 내연기관이 훼손되는 문제점 등이 있으며, 일본공개특허공보 소60-60178호는 에틸렌 글리콜 수용액 또는 프로필렌 글리콜 수용액을 주성분으로 한 "보일러용 열매체"에 관한 것으로서, 스케일 생성의 방지를 위해 인산 이온의 함유량을 50ppm이하로 한정하고 있으나 각종 금속의 재질에 적합한 부식방지제가 첨가되지 않아 보일러 내연기관 및 배관에 부식이 발생되는 등의 문제점이 있었고, 통상의 에틸렌 글리콜수용액에 부식억제제로 안식향소다와, 토릴트리아졸, 트리에탄올아민, 질산나트륨을, 안정제로 몰리브덴산나트륨을, pH 조정제로 수산화카륨을 첨가하여 개발된 대한민국 특허등록제422066호“보일러용 난방수 조성물”이 있으나, 이는 부식을 억제하는 효과는 있으나 열전도율이 기대에 어긋나 보일러용 난방수로서는 많은 문제점이 있는 것은 물론, 안식향소다와 토릴트리아졸은 초과 첨가 될 경우 충분한 용해가 되지 않아 오히려 스케일 생성의 원인이 되고, 트리에탄올아민은 질산염이 공존할 때 서로 반응하여 니로소아민이 생성되어 공해유 발의 원인이 되며, 질산나트륨과 아민류가 공존할 때 서로 반응하여 니트로소아민이 생성되는 등 실사용에 있어서 많은 문제점이 있을뿐더러 기존 난방수는 구성물의 제조원가가 너무 높아 대부분의 일반 소비자들은 사용을 기피하여 일반 수돗물을 사용하고 있는 실정이다.In order to solve the above problems, "liquid composition for thermal medium" based on ethylene glycol and water is disclosed in Korean Patent Publication No. 554 (March 26, 1988) and Korean Patent Publication No. 4064 (March 12, 1988) However, asbestos contained in the liquid composition for the heat medium and the emulsifier are combined and attached to the internal combustion engine and piping of the boiler, and the scale is formed, and the boiler internal combustion engine is damaged. No. 60178 relates to a "boiler heating medium" mainly composed of an aqueous solution of ethylene glycol or propylene glycol, which limits the content of phosphate ions to 50 ppm or less in order to prevent scale formation, but a corrosion inhibitor suitable for various metal materials is added. There was a problem such as corrosion occurs in the boiler internal combustion engine and piping, and the normal ethylene glycol Korean Patent Registration No. 422066 “Heating Water Composition for Boiler” developed by adding soda benzoate, toryltriazole, triethanolamine, sodium nitrate as a corrosion inhibitor to a solution, sodium molybdate as a stabilizer, and potassium hydroxide as a pH adjuster. However, this has the effect of suppressing corrosion, but the thermal conductivity is not expected, but there are many problems as heating water for boilers, of course, benzoic acid and tolyltriazole is not enough dissolved when it is added to cause the scale production. In addition, triethanolamine reacts with each other when nitrates coexist to cause nitrosamines, and causes pollution. In addition, there are many problems in practical use such as nitrosoamines reacting with each other when sodium nitrate and amines coexist. Existing heating water is too expensive to produce components Visas use ordinary tap water to avoid using it.
본 발명은 상기와 같은 지금까지 고안된 선행 물질들의 문제점들을 감안하여 실사용에 보다 적합하게 하기 위하여 안출된 것으로서, 정제 글리콜에 순수와 메칠알콜을 첨가하여 초기열전도율이 촉진되도록 하고 나트륨을 첨가하여 열전도율이 뛰어나면서도 3인산소다를 첨가하여 물때 등의 스케일이 생성되지 않도록 하여 열효율이 뛰어나면서도 보일러용 난방수를 교체하지 아니하고, 반영구적으로 사용할 수 있도록 하는 등 실사용에 문제가 없도록 하였으며 필요에 따라서는 헥사인산과, 인산염을 첨가하여 부식방지를 도모하고 글리세린을 첨가하여 비점을 상승시키며, 안식향소다를 첨가하여 순수가 부패하는 것을 방지하도록 함으로써 실사용에 유용하도록 함에 그 특징이 있다.The present invention was devised to make it more suitable for practical use in view of the problems of the prior art devised so far, by adding pure water and methyl alcohol to purified glycol to promote the initial thermal conductivity and by adding sodium, the thermal conductivity is increased. By adding excellent trisodium phosphate to prevent generation of scales such as scale, it is excellent in thermal efficiency and has no problem in actual use such as semi-permanent use without replacing the heating water for boiler. And it is characterized by the addition of phosphate to prevent corrosion and to increase the boiling point by the addition of glycerin, and by adding a benzoda to prevent the decay of pure water is useful in practical use.

여기서 본 발명의 주 성분인 글리콜은 자동차의 엔진 열을 라디에이터로 이동하여 방출하는 부동액의 주성분으로 이미 널리 사용되는 것으로 크게 에틸렌글리콜과 플로필렌글리콜 로 구분되는바 이를 70∼85중량%를 사용하게 된다.Here, glycol, which is a main component of the present invention, is already widely used as a main component of an antifreeze that moves and radiates the engine heat of an automobile to a radiator, and is largely divided into ethylene glycol and puffylene glycol, which uses 70 to 85% by weight. .
이와 같은 글리콜은 그 자체로는 부식방지 능력이 없을 뿐만 아니라 순환이 잘되지 않아 열전도율이 떨어지는 문제가 있다.Such glycols, as such, do not have corrosion resistance as well as poor circulation, which causes a problem of low thermal conductivity.
이에 본 발명을 안출함에 있어서 주된 목적으로 삼고 연구 개발한 것은 보일러의 열을 건물바닥으로 전도하는 보일러용 난방수 임을 감안하여 열전도율을 향상시키는데 최선의 목적을 두었다.
