Description

부식 및 보온성이 뛰어난 물탱크{Water tank with excellent corrosion and thermal resistance}Water tank with excellent corrosion and thermal resistance

본 발명은 식수 등으로 이용되는 스테인리스 재질의 물탱크의 부식방지, 단열성 향상 및 외부의 이물질 등의 부착성을 저하시켜 청결한 상태의 물탱크 상태를 유지하기 위한 부식 및 보온성이 뛰어난 물탱크에 관한 것이다.The present invention relates to a water tank excellent in corrosion and heat retention for maintaining a clean state of a water tank by reducing corrosion of the stainless steel water tank used for drinking water, etc., improving heat insulation and reducing adhesion of foreign substances, etc. .

물탱크는 대형 빌딩이나 아파트와 같이 용수를 대량으로 소비하는 시설에는 많은 양의 용수를 저장할 수 있도록 대형 물탱크가 설치되어 왔으며, 이러한, 물탱크는 매우 다양한 소재로 제작된다.Water tanks, such as large buildings or apartments, large water tanks have been installed to store large amounts of water in facilities that consume large amounts of water, and these water tanks are made of a wide variety of materials.

예컨대, 콘크리트 구조물, 스테인리스스틸, 유리섬유강화플라스틱(FRP:Fiber Glass Reinforced Plastics) 단위패널이나 SMC(Sheet Molding Compound) 단위패널 등 플라스틱 합성수지 단위패널이 널리 사용되고 있다.For example, plastic synthetic resin unit panels such as concrete structures, stainless steel, fiber glass reinforced plastics (FRP) unit panels or SMC (Sheet Molding Compound) unit panels are widely used.

SMC는 유리 섬유 강화 플라스틱(FRP)을 제조하기 위한 성형재료의 일종으로서, 적정한 가열 및 가압조건 하에서 성형하면 뛰어난 기계적 특성을 나타낼 뿐만 아니라 내식성 및 성형성이 우수하기 때문에 새로운 구조용 및 기능용 소재로 각광을 받으면서 그 활용범위가 점차 확대되어가고 있는 추세에 있으며, 특히 많은 종류의 물탱크들이 SMC 단위패널로 구축되고 있다.SMC is a type of molding material for manufacturing glass fiber reinforced plastics (FRP), and when molded under proper heating and pressure conditions, it not only exhibits excellent mechanical properties, but also has excellent corrosion resistance and moldability, so it is spotlighted as a new structural and functional material. The scope of its use is gradually increasing as it receives, and in particular, many types of water tanks are being constructed as SMC unit panels.

아울러, 아파트나, 공장, 산업시설 등에 각종 물탱크가 설치되어 단수시에도 식수나 산업용수를 안정적으로 공급할 수 있도록 하고 있다. 이러한 물탱크는 스테인리스 단위패널로 된 물탱크는 대용량이면서도 강도 및 충격에 강하여 널리 사용되고 있다.In addition, various water tanks are installed in apartments, factories, and industrial facilities to stably supply drinking water or industrial water even in the event of a single stage. These water tanks, which are made of stainless steel unit panels, are widely used due to their large capacity and strong strength and impact.

상기 스테인리스 단위패널로 된 물탱크는 여러 장의 단위패널을 서로 용접하여 수조를 형성하며, 각각의 단위패널은 수직 및 수평으로 배치되는 스테인리스 지주에 용접되어 지지된다.The water tank made of the stainless steel unit panel welds several unit panels to each other to form a water tank, and each unit panel is supported by being welded to a stainless steel column arranged vertically and horizontally.

이러한, 물탱크는 각각의 단위패널을 현장에서 서로 수밀되게 용접하여야 할 뿐만 아니라, 각각의 지주도 단위패널에 견고하게 고정되도록 용접되어야 하므로, 작업이 매우 번거로우며, 많은 시간과 인력이 소요되어 시설비가 증가 되는 문제점이 있다.In addition to this, the water tank must not only weld each unit panel to each other in a watertight manner, but also each pillar must be welded so as to be firmly fixed to the unit panel, so the work is very cumbersome, and requires a lot of time and manpower. There is a problem that is increased.

특히, 상술한 스테인리스 재질의 물탱크는 스틸재질로서 앞서 설명한 것과 같이 용접을 통해 수밀성을 형성하게 되는데 용접시 열에 의한 변형이 발생하게 되어 철 성분이 용철되기에 별도의 실링처리 및 부식을 방지하여야 한다.In particular, the above-mentioned stainless steel water tank is a steel material and forms watertightness through welding as described above. However, since heat deformation occurs during welding, an iron component is melted, so a separate sealing treatment and corrosion must be prevented. .

더욱이, 겨울철과 같이 외부온도가 낮을 경우 탱크 내의 물이 얼게 되면 재 기능을 상실하는 등의 문제점이 노출되었다.Moreover, when the outside temperature is low, such as in winter, problems such as loss of re-function when the water in the tank freezes have been exposed.

상기와 같은 문제점을 해결하기 위한 본 발명에 따른 부식 및 보온성이 뛰어난 물탱크는 스테인리스 재질의 물탱크에 부식방지 조성물 및 단열 조성물을 포함함으로써 부식방지 기능과 더불어 단열성을 높여 물탱크가 재기능을 수행할 수 있도록 하는데 그 목적이 있다.The water tank excellent in corrosion and heat retention according to the present invention for solving the above problems includes a corrosion protection composition and a heat insulation composition in a water tank made of stainless steel to increase the heat resistance with the corrosion prevention function, thereby performing the water function again. Its purpose is to make it possible.

본 발명의 또 다른 목적은 단열 조성물에 포함되는 코팅층에 의해 단열 효과와 더불어 외관의 이물질이나 먼지 등의 오염물이 잘 부착되지 않도록 하여 청결한 상태를 유지할 수 있도록 하는데 있다.Another object of the present invention is to maintain a clean state by preventing the contaminants such as foreign matter or dust from being externally attached, in addition to the thermal insulation effect by the coating layer included in the thermal insulation composition.

본 발명은 스테인리스 재질의 물탱크에 부식방지 조성물 및 단열 조성물을 포함함으로써 부식방지 기능과 더불어 단열성을 높여 물탱크가 재기능을 수행할 수 있다.The present invention includes a corrosion-resistant composition and a heat-insulating composition in a water tank made of stainless steel to increase the heat-insulating property as well as the corrosion-preventing function so that the water tank can perform a re-function.

아울러, 단열 조성물에 포함되는 코팅층에 의해 단열 효과와 더불어 외관의 이물질이나 먼지 등의 오염물이 잘 부착되지 않도록 하여 청결한 상태를 유지할 수 있는 유용한 발명이다.In addition, it is a useful invention that can maintain a clean state by preventing a contaminant such as foreign matter or dust from being externally attached in addition to the thermal insulation effect by the coating layer included in the thermal insulation composition.

상기 세라믹 분말(31)은 알루미노 실리케이트를 주성분으로 하는 세라믹의 미세한 원형 중공체 분말입자이다.The ceramic powder 31 is a fine circular hollow powder particle of a ceramic containing alumino silicate as a main component.

따라서, 세라믹 분말(31)은 내부가 비워져 있는 형태로 제작되어 단열층을 형성함으로써 단열효과를 높일 수 있게 된다.Accordingly, the ceramic powder 31 is manufactured in a form in which the inside is emptied, thereby forming a heat insulating layer to enhance the heat insulating effect.

이러한, 세라믹 분말(31)은 특별히 한정하는 것은 아니지만 입도가 30 ∼ 100㎛로 제작되는 것이 좋다.The ceramic powder 31 is not particularly limited, but is preferably made to have a particle size of 30 to 100 µm.

또한, 상기 세라믹 분말(31)의 표면에 코팅되는 코팅층(32)은 비스페놀 F 타입 에폭시수지와 아크릴수지를 7 : 3의 중량비율로 혼합한 에폭시 아크릴수지 30 ∼ 40중량%, 유화제 3 ∼ 7중량%, 물 50 ∼ 60중량%, 소포제 1 ∼ 3중량%, 접착력 증강제 2 ∼ 3중량%로 이루어진 주제와, 지방족 폴리아민 45 ∼ 50중량%, 유화제 2 ∼ 5중량%, 경화촉진제 2 ∼ 3중량%, 물 45 ∼ 50중량%로 이루어진 경화제로 이루어지되, 주제와 경화제는 5 : 1의 중량비율로 혼합하여 구성된다.In addition, the coating layer 32 coated on the surface of the ceramic powder 31 is 30-40% by weight of an epoxy acrylic resin mixed with a bisphenol F-type epoxy resin and an acrylic resin in a weight ratio of 7: 3, 3-7 weight of emulsifier. %, 50 to 60% by weight of water, 1 to 3% by weight of antifoaming agent, 2 to 3% by weight of adhesion enhancer, 45 to 50% by weight of aliphatic polyamine, 2 to 5% by weight of emulsifier, 2 to 3% by weight of curing accelerator , Consisting of a curing agent consisting of 45 to 50% by weight of water, the main agent and the curing agent is composed by mixing in a weight ratio of 5: 1.

- 코팅층의 주제-Theme of coating layer

1. 에폭시 아크릴수지1. Epoxy acrylic resin

상기 주제를 구성하는 에폭시 아크릴 수지는 비스페놀 F 타입 에폭시수지와 아크릴수지로 이루어져 있다.The epoxy acrylic resin constituting the above-mentioned subject consists of bisphenol F type epoxy resin and acrylic resin.

여기서, 상기 비스페놀 F 타입 에폭시수지는 주제를 구성하는 주 구성요소로서 비스페놀 A타입 에폭시수지보다 인체에 미치는 유해성이 없고 냄새가 없으며, 각종 경화제와 반응성이 좋아 물성이 우수해지는 성질이 있다.Here, the bisphenol F-type epoxy resin is a main component constituting the subject, and has no harmful effect on the human body and has no odor, and has good reactivity with various curing agents, thereby improving physical properties.

또한, 아크릴수지는 실리콘아크릴레이트모노머 18 ∼ 40, 트리(프로필렌글리콜) 디아크릴레이트 35 ∼ 60, 유기용제로서 크실렌 10 ∼ 20중량%, 개시제 0.5 ∼ 5중량%로 이루어져 있다.Further, the acrylic resin is composed of silicone acrylate monomers 18 to 40, tri (propylene glycol) diacrylate 35 to 60, and xylene 10 to 20% by weight as an organic solvent and 0.5 to 5% by weight as an initiator.

이러한, 아크릴수지의 실리콘아크릴레이트모노머는 먼지나 이물질 등의 부착방지성이 우수하고, 실리콘 말단기에 아크릴레이트가 있어 수지합성이 가능한 성분으로서, 임계치 미만일 경우에는 먼지나 이물질 등의 부착방지성이 불량하게 되고, 임계치를 초과하게 되면 비스페놀 F 타입의 에폭시수지와의 부착성이 저하되는 문제점이 있다.The silicone acrylate monomer of the acrylic resin has excellent adhesion prevention properties such as dust and foreign substances, and is a component capable of resin synthesis due to the presence of acrylate at the silicone end. There is a problem in that the adhesiveness with the bisphenol F type epoxy resin deteriorates when it becomes poor and exceeds the threshold.

또한, 트리(프로필렌글리콜) 디아크릴레이트는 성분들 간의 부착성을 향상시키고, 건조성, 내후성이 우수한 성분으로 임계치 미만으로 혼합하였을 경우 도막형성이 불량하게 이루어지고, 임계치를 초과하여 혼합하게 되면 먼지나 이물질 등의 부착방지성이 약해지는 문제점이 있다.In addition, tri (propylene glycol) diacrylate improves adhesion between components, and when it is mixed below a threshold with excellent dry and weather resistance, film formation is poor, and when mixed above the threshold, dust However, there is a problem in that the anti-adhesive properties of foreign substances are weakened.

또한, 유기용제로서 크실렌은 상기 성분들을 혼합하기 위해 액상으로 만들기 위한 것으로 특별한 설명은 생략한다.In addition, xylene as an organic solvent is intended to be made into a liquid to mix the components, and a special description is omitted.

한편, 본 발명에서의 코팅층(32)을 구성하는 주제의 에폭시 아크릴 수지는 7 : 3의 중량비율로 이루어져 있는데, 이러한 비스페놀 F 타입 에폭시수지는 임계치 미만이면 코팅막 형성이 어렵고, 임계치를 초과할 경우 점도 상승이 발생할 수 있고, 에폭시 아크릴 수지는 먼지나 이물질 등의 부착방지성 및 비스페놀 F 타입 에폭시수지와의 부착성, 내후성이 우수한 성분으로 임계치 미만일 경우 먼지나 부착방지성 및 비스페놀 F와의 부착성을 기대할 수 없고, 임계치를 초과할 경우 비스페놀 F 타입의 에폭시수지의 양의 감소로 인해 코팅층(32) 형성이 어려운 문제가 있다.On the other hand, the epoxy acrylic resin of the subject constituting the coating layer 32 in the present invention is composed of a weight ratio of 7: 3, such bisphenol F-type epoxy resin is difficult to form a coating film below the threshold, viscosity when exceeding the threshold Elevation may occur, and the epoxy acrylic resin is a component that has excellent adhesion prevention properties such as dust and foreign substances, adhesion to bisphenol F-type epoxy resins, and weather resistance.

Curing reactivity between the primary amine group and the epoxy group is relatively good, and is often used.

이러한 지방족 아민은 변성시켜 수용화하여 사용하므로 자극적인 냄새가 없고 인체에 자극이 없다.Since these aliphatic amines are modified and water-soluble, there is no irritating odor and no irritation to the human body.

2. 유화제2. Emulsifier

유화제는 주제에 사용한 유화제와 동일한 유화제를 사용하게 된다.The emulsifier is the same emulsifier used in the subject.

Therefore, it is used as a curing accelerator.

한편, 본 발명에서의 코팅층(32)의 주제와 경화제는 5 : 1의 중량비율로 혼합하여 구성되는데, 이는, 주제의 에폭시 아크릴수지의 이물질이나 먼지 등의 부착력 방지성을 위해 주제가 경화제보다 더 많은 양이 투입어야만 한다.On the other hand, the subject of the coating layer 32 in the present invention and the curing agent are composed by mixing at a weight ratio of 5: 1, which is more subject than the curing agent for preventing adhesion of foreign matter or dust of the subject's epoxy acrylic resin. The amount must be added.

특히, 본 발명에서는 부식방지 조성물(20)과 단열 조성물(30)을 2 : 1의 부피비로 혼합하여 사용하게 되는데, 이는 부식방지 조성물(20)은 부식방지 기능과 더불어 물탱크(10) 표면에 부착성능이 뛰어난 재질로 이루어져 있지만, 고체형태의 단열 조성물(30)의 양이 더 많을 경우 부착성능이 저하될 수 있기 때문에 혼합비를 맞춰야 하며, 만약, 부식방지 조성물(20)의 양이 적을 경우에는 단열 조성물(30)의 부착성능이 저하되는 문제가 발생하게 되고, 부식방지 조성물(20)의 양이 많을 경우에는 물탱크(10)의 표면에 고르게 분포되어야하는 단열 조성물(30)이 고르게 분포되지 않게 되어 단열 효율성이 저하됨은 물론, 단열 조성물(30)의 세라믹(31) 표면의 코팅층(32)의 이물질 및 먼지 등의 부착방지성의 효과를 기대하기 어렵게 된다.In particular, in the present invention, the anti-corrosion composition 20 and the heat-insulating composition 30 are mixed and used in a volume ratio of 2: 1, which is used for the anti-corrosion composition 20 on the surface of the water tank 10 in addition to the anti-corrosion function. It is made of a material with excellent adhesion performance, but if the amount of the heat insulating composition 30 in a solid form is larger, the mixing ratio must be adjusted because the adhesion performance may be lowered. If the amount of the corrosion preventing composition 20 is small, The problem that the adhesion performance of the insulating composition 30 decreases occurs, and when the amount of the corrosion-preventing composition 20 is large, the insulating composition 30 that should be evenly distributed on the surface of the water tank 10 is not evenly distributed. Not only that, the insulation efficiency is lowered, and it is difficult to expect the anti-adhesive effect of the foreign matter and dust of the coating layer 32 on the surface of the ceramic 31 of the insulation composition 30.

상술한 바와 같이 본 발명은 부식방지 조성물(20)을 통한 스테인리스 재질의 물탱크(10)의 부식방지 기능은 물론, 단열 조성물을 통한 단열 효과와 더불어 물탱크(10) 표면의 이물질이나 먼지 등의 부착력 방지성을 향상시켜 향상 청결한 상태의 물탱크를 유지할 수 있는 효과를 얻을 수 있게 되는 것이다.As described above, the present invention not only prevents corrosion of the stainless steel water tank 10 through the anti-corrosion composition 20, but also prevents foreign matter or dust on the surface of the water tank 10, as well as the heat-insulating effect through the heat-insulating composition. By improving the adhesion preventing property, it is possible to obtain an effect of maintaining the water tank in a clean state.

상술한 실시 예는 본 고안의 가장 바람직한 예에 대하여 설명한 것이지만, 상기 실시 예에만 한정되는 것은 아니며, 본 고안의 기술적 사상을 벗어나지 않는 범위내에서 다양한 변형이 가능하다는 것은 본 발명이 속하는 기술분야에서 통상의 기술자들에게 있어 명백한 것이다.Although the above-described embodiment is described with respect to the most preferred example of the present invention, it is not limited to the above-described embodiment, and various modifications are possible within the scope without departing from the technical spirit of the present invention.
