Description

규산염을 주성분으로한 복합염 방청제의 제조 방법Method for producing composite salt rust preventive based on silicate

본 발명은 본출원인이 선출원(특허 공고번호 제96-13482호)하여 등록된 규산염 제조 방법으로 제조한 규산염 방청제를 이용하여 규산염을 주성분으로한 복합염방청제의 제조 방법에 관한 것으로, 특히 규산염 방청제 60 ~ 80wt%, 피로인산소다 10 ~ 23wt%, 제3인산소다 7 ~ 14wt%, 트리포리인산소다 1.5 ~ 3wt%, 탄산칼슘 0 ~ 1wt%를 배합하여 복합염 방청제를 제조하여 계절적 수온의 변화에 따라 복합염 방청제의 용해도 성능을 일정토록 하여 인체에 해가 없도록할 뿐만 아니라 상기 배합물이 저온에서도 용해되므로서 에너지 절약은 물론 물과 접촉하는 보일러 및 파이프 내부의 부식 억제와 수질을 근본적으로 청정시키는 역할을 하면서 공해를 줄일 수 있도록 한 것에 관한 것이다.The present invention relates to a method for producing a composite salt rust preventive agent containing silicate as a main component by using a silicate rust preventive agent prepared by a method of preparing silicate registered by the present applicant (Patent Publication No. 96-13482). ~ 80wt%, sodium pyrophosphate 10-23wt%, trisodium triphosphate 7-14wt%, tripolyphosphoric acid 1.5 ~ 3wt%, calcium carbonate 0-1wt% to prepare a composite salt rust inhibitor to change the seasonal water temperature As a result, the solubility performance of the composite salt rust preventive agent is not only harmless to the human body, but also the compound is dissolved at low temperatures, thereby saving energy and fundamentally cleaning corrosion and water quality in boilers and pipes in contact with water. To reduce pollution while doing so.

일반적으로 상시 물에 잠겨 있는 순환배관 또는 습곡 용기등의 표면은 여러 가지 부식인자에 의하여 금속 표면이 부식되거나 스케일이 적층되어 관이 막히고 이로 인하여 통수용량의 감소, 녹물의 발생등으로 말미암아 수도관을 통하여 각가정에 급수되는 물을 식수로 이용하는 사람에게 인체에 해를 가져다주며, 아파트의 경우 말단의 급수 탱크, 직경이 적은 가정용 급수관, 급수 기구등의 부식으로 인해 관이나 기구의 교체로 인한 경제적 손실이 매우 컸었다.In general, the surface of a circulation pipe or a foldable container which is always immersed in water is corroded by metal corrosion or scales are blocked by various corrosion factors, which leads to a blockage of the pipe. It harms the human body to people who use water supplied to each household as drinking water.In the case of apartments, the economic loss due to the replacement of pipes or appliances due to the corrosion of the water supply tank at the end, the small diameter home water supply pipe, and the water supply equipment It was very big.

상기와 같은 여러 가지 문제점을 해결하고자 수도관이나 배수관 내부에 부식을 막기 위하여 보건복지부가 규정한 수처리 제1종인 인산염, 제2종인 규산염 또는 인산염과 규산염을 혼합한 제3종인 복합염으로 된 알갱이를 저수 탱크에 넣은 다음 일정치로 물에 용해되도록 하여 각 가정에서 물을 사용할 때 물과 함께 용해된 방청제가 관을 따라 급,배수되면서 물을 청정시키고 또한 관의 내벽에 얇은 막이 도포되면서 부식이 방지되는 방법을 이용하고 있다.In order to solve the various problems as described above, in order to prevent corrosion in the water pipe or the drain pipe, the water treatment granules of the first type of water treatment prescribed by the Ministry of Health and Welfare, the second type of silicate, or the third type of mixed salt of phosphate and silicate are stored. Put it in a tank and dissolve it in water at a certain level so that when using water in each household, the rust inhibitor dissolved with water is supplied and drained along the pipe to clean the water, and a thin film is applied to the inner wall of the pipe to prevent corrosion. The method is used.

그러나 상기 방청제의 제1종인 인산염을 사용할 경우 강,하천의 부영양화를초래하고, 또 수도관내의 납성분을 용출할 뿐만 아니라 과다한 인산염 섭취시 기형아의 출산이나 혈관경화,요독증,신경화증,고혈압과 같은 인체에 질병을 초래하게된다고 하여 법정법인인 한국수도협회에서도 저수조 관리 지침에 인산염 방청제의 폐단을 지적하고 있다.However, the use of phosphate, the first type of rust preventive agent, leads to eutrophication of rivers and rivers, and elutes lead components in the water pipes, and excessive human consumption such as birth defects, vasosclerosis, uremia, neurosclerosis, and hypertension. The Korean Capital Association, a legal corporation, points out the closure of phosphate rust inhibitors in the reservoir management guidelines.

따라서 인체에 해를 끼치지 않고 관의 부식도 막아 줄 수 있는 복합염 방청제의 제조 방법을 안출하여 선출원한 특허공보 제2780호 공고번호 92-4017에는 규산염과 인산염의 복합 조성으로된 복합염 방청제의 제조 방법으로 금속용 청정제를 생산하여 왔었다.Therefore, Korean Patent Publication No. 2780 Publication No. 92-4017, which proposes a method for producing a composite salt rust preventive agent that can prevent corrosion of a tube without harming the human body, discloses a composite salt rust inhibitor having a complex composition of silicate and phosphate. Metal cleaning agents have been produced by the manufacturing method.

그러나 상기의 복합염 방청제 제조 방법은 규석과 인산염 및 무수탄산나트륨 피로인산 나트륨 제3인산 나트륨을 소정의 비율로 혼합하여서 혼합물을 전기 용광로에 넣어 1650℃의 온도로 12시간 가열하여 용해시킨 다음 냉각시켜 크리스탈 형상으로 복합염을 제조하여 왔었는데 이것은 주성분인 규석과 무수탄산 나트륨 등의 혼합물을 용해시키는데 1650℃ 이상의 온도로 열을 가해야 하므로 에너지 소모가 많아 경제적 비용의 상승으로 원가가 높을 뿐만 아니라 제조 시간이 많이 소요되므로서 생산성이 떨어지며, 또한 이와같이 제조된 복합염은 계절별로 수온의 차이에 의하여 물에 용해되는 비율이 다르기 때문에 방청제로서의 역할을 제대로 할 수 없는 문제점이 있었다.However, the method for preparing a composite salt rust preventive agent is a mixture of silica, phosphate and anhydrous sodium pyrophosphate trisodium phosphate in a predetermined ratio, the mixture is put into an electric furnace, heated to a temperature of 1650 ℃ for 12 hours to dissolve and then cooled crystal Complex salts have been produced in the form, which dissolves the mixture of silica and anhydrous sodium carbonate, which are the main components, and needs to be heated at a temperature of 1650 ℃ or higher, resulting in high energy consumption and high cost as well as high production time. Productivity is reduced because it takes a lot, and also the composite salt prepared in this way has a problem that can not properly serve as a rust preventive agent because the rate of soluble in the water by the difference in water temperature varies by season.

본 발명인 복합염 방청제는 상기한 점을 감안하여 안출된 것으로서, 관에 대한 방청효능이 탁월하고, 수중의 금속이온도 봉쇄화시키며 과다 용출로 인한 음용수계통의 문제점인 용해도도 수온의 변화에 따라 용해도를 조정하여 세계 각국의 상시 수온을 고려하여 인체에 무해, 무미, 무취하도록 음용수를 공급할 수 있는 복합염 방청제 제조 방법을 제공하는 데 그 목적을 둔다.The composite salt rust preventive agent of the present invention was devised in view of the above-mentioned point, and the anti-rusting effect on the tube was excellent, and the solubility according to the change of the water temperature, which is a problem of the drinking water system due to the temperature blockade of the water and the excessive elution. The purpose of the present invention is to provide a method for preparing a composite salt rust preventive agent that can supply drinking water to be harmless, tasteless, and odorless to the human body in consideration of the constant water temperature of countries around the world.

상기의 목적을 달성하기 위해서는, 본출원인이 선출원하여 등록된 규산염 제조방법으로 제조된 규산염 방청제 60 ~ 80wt%, 피로인산소다 10 ~ 23wt%, 제3인산소다 7 ~ 14wt%, 트리포리인산소다 1.5 ~ 3wt%, 탄산칼슘 0 ~ 1wt%를 배합한 혼합물을 용광로에 넣고 1200℃로 6시간 가열한 다음 냉각시켜 소정의 모양으로 성형하므로서 그 목적은 달성된다.In order to achieve the above object, 60 to 80 wt% of silicate rust inhibitor manufactured by the method of silicate preparation registered by the present applicant in advance, 10 to 23 wt% of sodium pyrophosphate, 7 to 14 wt% of trisodium phosphate, and sodium tripolyphosphate 1.5 The object is achieved by placing a mixture containing ˜3 wt% and calcium carbonate 0-1 wt% in a smelting furnace, heating at 1200 ° C. for 6 hours, and then cooling to form a predetermined shape.

이와같이 제조된 본발명의 복합염 방청제의 인산(P2O2) 함량은 기존 인산염 방청제의 5~9%에 불과하므로 친환경적 제품이다.The phosphoric acid (P2O2) content of the composite salt rust inhibitor of the present invention prepared as described above is only 5 to 9% of the existing phosphate rust inhibitor, so it is an environmentally friendly product.

도 1에 도시된 바와같이 본출원인이 선출원(특허 공고번호 제96-13482호)한 순수규산 99.8%의 규석분말 72%중량, 무수탄산나트륨 24.2%중량, 알루민산나트륨 0.5%중량, 탄산카리 2.5%중량, 산화알루미늄 0.3%중량, 이산화망간 0.5%중량을 믹서하여 1500-1700℃의 전기 이중로에 용해시켜 전기로에 의하여 제조한 규산염 방청제 60 ~ 80wt%, 피로인산소다 10 ~ 23wt%, 제3인산소다 7 ~ 14wt%, 트리포리인산소다 1.5 ~ 3wt%, 탄산칼슘 0 ~ 1wt%를 배합한 혼합물을 용광로에 넣고 1200℃로 가열한 다음 냉각시켜 소정의 모양으로 성형하는 방법이다.As shown in FIG. 1, 72% by weight of 99.8% of pure silicic acid powder, 24.2% by weight of anhydrous sodium carbonate, 0.5% by weight of sodium aluminate, and 2.5% of carbonic carbonate, of which the applicant has filed an application (Patent Publication No. 96-13482). 60 to 80 wt% of silicate rust inhibitor prepared by an electric furnace by mixing the weight, 0.3% by weight of aluminum oxide and 0.5% by weight of manganese dioxide in an electric double furnace at 1500-1700 ° C., 10 to 23 wt% of sodium pyrophosphate and trisodium phosphate A mixture of 7 to 14 wt%, 1.5 to 3 wt% of sodium tripolyphosphate, and 0 to 1 wt% of calcium carbonate is placed in a furnace, heated to 1200 ° C., and then cooled to form a predetermined shape.

상기 방청력과 용해도가 일정한 규산염 방청제를 주재료로 60 ~ 80wt%를 사용하므로서 방청효과와 용해력을 안정화시키고, 이 규산염은 1200℃에서 용해된다.By using a silicate rust inhibitor with a constant rust preventive power and solubility as a main material, the rust preventive effect and solubility are stabilized, and the silicate is dissolved at 1200 ° C.

피로인산소다는 10 ~ 23wt%를 배합하여 철청오점(鐵淸汚點)제거 능력을 가짐으로서 방청 능력을 향상시키며 용수중의 경수 성분인 Mg2+, Ca2+에 가용성 착화합물을 만들어 불용성분을 봉쇄하는 역할도하며 융점 983℃에서 무수물로 용해된다.Sodium pyrophosphate by blending 10 ~ 23wt% to cheolcheong blot (鐵淸汚點) improving the rust preventing ability by having the ability to remove hard water sikimyeo component, Mg 2+, insoluble components create a soluble complex compounds on Ca 2+ in the water It also acts as a blockade and dissolves in anhydrides at 983 ° C.

제3인산소다는 물에 녹이면 무제한 녹는 용해의 성질을 이용하여 복합염 방청제의 용해도를 조정하는 역할을 하게되는 것으로 7 ~ 14wt%의 조성비로 조절한다.Sodium triphosphate is used to adjust the solubility of the composite salt rust preventive by using the property of unlimited dissolution when dissolved in water, it is adjusted to the composition ratio of 7 ~ 14wt%.

또한, 탄산칼슘은 3인산소다와 함께 용해도의 조정을 담당하며 조성비는 0 ~ 1wt%로서 규산염과 조합하여 용해로의 용융온도를 낮추어 주는 역할을 하게 하고 트리포리인산소다는 수중의 금속이온을 봉쇄하는 금속이온 봉쇄제로서 조성비를 1.5 ~ 3wt%로 조절하여 효과적으로 경수를 연수화하는 한편, 분산력도 좋아서 용융시 규산염과 다른 약제를 고르게 분산 용해시킨다.In addition, calcium carbonate, together with sodium triphosphate, is responsible for the adjustment of solubility. The composition ratio is 0 to 1wt%, which is combined with silicate to lower the melting temperature of the melting furnace and tripolyphosphate blocks the metal ions in the water. As a metal ion sequestrant, the composition ratio is controlled to 1.5 to 3 wt% to soften hard water effectively, while dispersing power is good, so that silicate and other drugs are dispersed and dissolved evenly during melting.

상기와 같이 규산염 방청제와 피로인산소다, 제3인산소다, 탄산칼슘 및 트리포리인산소다를 적정한 비율로 배합하여 복합염 방청제를 제조하는 방법은 설명하면 다음과 같다.As described above, a method of preparing a composite salt rust preventive agent by mixing a silicate rust preventive agent with sodium pyrophosphate, trisodium phosphate, calcium carbonate, and sodium tripolyphosphate in an appropriate ratio is as follows.

먼저 용해로의 로(爐)내 온도를 1000℃의 온도로 예열후 규산염 방청제를 입도 0.5m/m로 분쇄하여 분말화한 뒤 상기 분말된 규산염 방청제 60 ~ 80wt%, 피로인산소다 10 ~ 23wt%, 제3인산소다 7 ~ 14wt%, 트리포리인산소다 1.5 ~ 3wt%, 탄산칼슘 0 ~ 1wt%를 적정한 비율로 배합하여 용융로에 투입한다.First, the furnace temperature of the melting furnace is preheated to a temperature of 1000 ° C., and then the silicate rust inhibitor is pulverized to a particle size of 0.5 m / m to powder and then powdered silicate rust inhibitor 60 to 80 wt%, sodium pyrophosphate 10 to 23 wt%, 7 to 14 wt% of trisodium phosphate, 1.5 to 3 wt% of tripolyphosphoric acid, and 0 to 1 wt% of calcium carbonate are blended in an appropriate ratio and introduced into a melting furnace.

다만 수온이 낮은 북유럽 지역이나 북중미 지역에 사용할 때에는 도1의 실시예2에 도시된 바와같이 탄산칼슘은 혼합하지 않는다.However, when used in the northern European region or the North Central America region where the water temperature is low, calcium carbonate is not mixed as shown in Example 2 of FIG.

사용되는 용융로는 전기로, 개스로, 경유로 중에서 1200℃ 정도의 로(爐)내 온도를 유지할 수 있는 것은 가능하다.The melting furnace used can maintain the furnace temperature of about 1200 degreeC in an electric furnace, a gas furnace, and a diesel oil passage.

로(爐)내 온도가 높으면 높을수록 용융시간을 줄일 수 있으며 6시간 경과후 완전 용해와 동시에 중합이 이루어지면 출탕용 주물 용기에 담아 냉각 고형화시키면 무색 투명한 유리상의 파쇄형 제품이 되는 것이다.The higher the temperature in the furnace, the shorter the melting time. After 6 hours of complete dissolution and polymerization at the same time, the solidification in the casting container for tapping and cooling solidifies the product into a colorless transparent glassy product.

도 1에서 실시예1의 배합율로 제조된 복합염 방청제는 비교적 수온이 높은 아열대성 기후에 적합한 용해도를 갖고 있는 방청제로 판명되었고The composite salt rust inhibitor prepared at the blending rate of Example 1 in FIG. 1 was found to have a solubility suitable for a subtropical climate having a relatively high water temperature.

실시예2의 배합율로 제조된 복합염 방청제는 수온이 낮은 북유럽 및 북중미 지역에 맞는 방청제임이 용해도 시험(도3)과 방청효과시험(도4)에서 입증되었다.The composite salt rust inhibitor prepared at the blending rate of Example 2 was proved in the solubility test (FIG. 3) and the rust prevention effect test (FIG. 4) as a rust inhibitor suitable for the Nordic and North Central America regions with low water temperature.

또한, 실시예3은 우리나라 봄, 가을 계절에 수온정도 즉16℃-18℃의 온도에서 적합한 용해도를 갖고 있는 것으로서In addition, Example 3 has a suitable solubility at the temperature of the water temperature, that is, 16 ℃ -18 ℃ in the spring and autumn season of Korea as

도1에서의 조성물의 배합율로 혼합하여 제조한 복합염 방청제는 원자흡광 광도계를 이용하여 중금속의 분석 결과 도2와 같이 보건복지부가 고시한 급수용 방청제 관리 지침에서 정한 기준치 허용치보다 훨신 밑도는 수치를 기록하였고 급수용 방청제 검사 기준에도 적합한 방청제로 입증되었다.The composite salt rust preventive agent prepared by mixing at the composition of the composition in Figure 1 using a atomic absorption spectrophotometer as a result of the analysis of heavy metals as shown in Figure 2 far below the allowable value set by the Ministry of Health and Welfare notified by the guidelines for management of rust preventive for water It was proved to be suitable to the inspection criteria of water rust preventive.

도3a,3b,3c에 도시된 바와같이 수온별 용해도 시험은 수온 5℃,15℃,25℃에서 각 방청제 10g이 증류수 200㎖에 용해되는 양을 측정한 것으로 본 발명의 복합염 방청제의 용해도 성능이 일정함을 나타내고 있는 것을 알 수 있습니다.As shown in FIGS. 3a, 3b, and 3c, the solubility test for each water temperature measured the amount of 10 g of the rust inhibitors dissolved in 200 ml of distilled water at a water temperature of 5 ° C, 15 ° C, and 25 ° C. You can see that it represents this constant.

도4에 도시된 바와같이 방청효과의 시험은 방청제를 액화시켜 1㎖를 증류수 100㎖에 첨가하여 시편(KS D 3506 SBHGI 강판)을 넣어 수온 5℃,15℃,25℃에서 측정한 결과 본 복합염 방청제의 방청효과가 각 온도에서 탁월한 것을 알 수 있다. 예를 들면 타방청제는 수온 5℃에서는 거의 녹지 않아 용해도 및 방청효과는 미미하였고 수온이 하강할수록 용해되지 않았으나 본 발명의 복합염 방청제는 일정한 용해도를 나타내고 있다.As shown in Fig. 4, the test of the rust prevention effect was obtained by liquefying the rust inhibitor and adding 1 ml to 100 ml of distilled water and adding the specimen (KS D 3506 SBHGI steel sheet) at water temperature of 5 ° C, 15 ° C and 25 ° C. It can be seen that the antirust effect of the salt rust preventive agent is excellent at each temperature. For example, the other anti-corrosive agent is hardly dissolved at a water temperature of 5 ° C., so that the solubility and the rust-preventing effect are insignificant. As the water temperature drops, the other rust preventive agent has a constant solubility.

또한, 수온 25℃의 조건에서는 타 방청제는 수온이 증가하면 용해도가 거의 2배가 높아 과다용출되는 현상을 보이고 있지만 본 발명인 복합염 방청제는 수온이 높더라도 용해도가 일정하다는 것을 알 수 있는 것입니다.In addition, under the condition of water temperature of 25 ℃, the other rust inhibitor shows a phenomenon that the solubility is almost twice as high as the water temperature increases, but the composite salt rust inhibitor of the present invention can be seen that the solubility is constant even if the water temperature is high.

이와같이 본 발명인 복합염 방청제는 계절에 따라 수온의 변화에 의한 용해도가 일정한 방청제를 이용하므로서 국민 건강에 필수적인 것임을 알 수 있는 것이다.As described above, the inventors of the present invention provide a composite salt rust preventive agent solubility due to changes in water temperature according to the season is essential for the public health by using a constant rust preventive agent.

상기한 실시예를 갖는 본 발명은, 수온의 변화에 따라 용해도를 조정할 수 있도록 조성물을 배합하여 제조한 복합염 방청제를 상시 수온에 맞는 것을 이용하므로서 인체에 무해,무미,무취하고 안전한 음용수를 세계 어느 지역에서나 공급할 수 있는 효과가 있을 뿐만 아니라,The present invention having the above-described embodiment, the composite salt rust preventive agent prepared by mixing the composition so that the solubility can be adjusted according to the change of the water temperature, which is always harmless to the human body by using a suitable water temperature, tasteless, odorless and safe drinking water Not only can you deliver locally,

본출원인이 발명 제조한 규산염을 주재료로하고 이 규산염은 규석이 용융되는 온도보다 낮은 1200℃의 온도에서도 용융되기 때문에 용융 온도로 가열하는 데 종래보다도 많은 에너지를 절약할 수 있어서 원가 절감 및 생산성 향상의 효과도 있게 한 것이다.The main application is the silicate manufactured by the present invention, and since the silicate is melted even at a temperature of 1200 ° C, which is lower than the temperature at which the silica is melted, it is possible to save more energy than before when heating to the melting temperature, thereby reducing the cost and improving productivity. It also worked.
