Description
본 발명은 칼라 씽크볼에 관한 것으로, 보다 상세하게는 스테인레스로 제조된 은색의 씽크볼을 분체도장하여 특정 색상을 갖도록 다채롭게 구현하여 소비자의 구매욕구를 증대시키면서 주방 장식미를 강화시킨 칼라 씽크볼에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a color Thinkball, and more particularly, to a color Thinkball in which a silver decorative ball made of stainless steel is powder coated to various colors to enhance consumers' purchasing desires.
일반적으로 가정의 주방에는 씽크대가 필수로 설치되며, 씽크대는 각종 용기를 보관할 수 있는 수납실과 함께 그 상부에는 씽크볼(일명, '개수대'라고도 함)이 설치되어 음식물을 씻거나 설거지 등을 행할 수 있도록 되어있다.Generally, a sink is necessary in the kitchen of a home. The sink is equipped with a storage room for storing various containers, and a sink ball (also known as a "wash basin") is installed at the upper part of the sink so that food can be washed or washed. .
이와 같은 씽크대를 이루는 씽크볼은 보통 부식이 없는 스테인리스 소재로 성형된 것으로서, 소정의 깊이로 함몰 형성되며, 함몰된 바닥면에는 물 빠짐을 위한 배수통이 마련된다.Such a sink is generally formed of corrosion-free stainless steel and is recessed to a predetermined depth, and a drainage pipe for draining water is provided on the recessed bottom surface.
그리고, 배수통은 씽크볼의 바닥면으로부터 탈부착 가능한 형태로 설치되며 배수관과 연결되고, 배수통 내에는 음식물 슬러지나 쓰레기를 걸러낼 수 있도록 용기형태를 갖는 여과통이 구비되며, 배수통의 상부에는 여과통을 은폐시키면서 일차적으로 큰 음식물 슬러지나 찌꺼기를 걸러주고 물을 배출시킬 수 있는 덮개가 구비되는 형태를 갖는다.The drain canister is installed in a form detachable from the bottom surface of the sink ball and is connected to the drain pipe. The drain canister is provided with a filter box having a container shape so as to filter food sludge or waste. And a lid capable of filtering out large food sludge or debris and discharging the water is provided.
그리하여, 사용자가 음식물을 씽크볼에서 다듬거나 설거지하는 가운데 물 내림과 함께 일부 작은 음식물 슬러지나 찌꺼기들은 모두 여과통으로 유입되어 걸러지며 물은 배수통과 배수관을 통하여 배출된다.Thus, as the user smoothes or dishes the food in the sink bowl, the water drops and some small food sludge or debris flows into the filter bag and is filtered and the water is discharged through the drainage pipe.
그런데, 통상적인 씽크볼은 스테인레스로 제조되기 때문에 천편일률적으로 은색을 띠기 때문에 다양성이 떨어져 젊은 장식미가 떨어지므로 특히 젊은 소비자층에게 어필하기 어렵다는 한계에 봉착해 있다.However, since ordinary Thinkball is made of stainless steel, it is difficult to appeal to the younger consumers because the diversity is falling and the young ornamental beauty drops because it is made of silver.

본 발명에 따른 칼라 씽크볼은 아래 참고사진의 예시와 같이, 다양한 색상을 갖도록 구현됨으로써 다채로운 색상미에 따른 주방 인테리어 효과를 증대시켜 거주자의 만족도를 강화시키도록 구성된다.The color Sinkball according to the present invention is configured to have various colors as shown in the following reference photographs, thereby enhancing the kitchen interior effect resulting from various colors, thereby enhancing the satisfaction of residents.

이때, 씽크볼은 보통 스테인레스로 제조되기 때문에 표면 색상은 모두 은색이다.At this time, since Thinkball is usually made of stainless steel, the surface color is all silver.
이에, 본 발명에서는 은색의 스테인레스 표면을 1차로 분체도장하여 특정 색상을 갖는 하도층을 형성하고, 하도층이 형성된 후 완전히 건조되면 상기 하도층 위해 2차로 투명한 상도층, 즉 표면보호층을 형성함으로써 다양한 색상 구현이 가능하도록 구성된다.Accordingly, in the present invention, a silver colored stainless steel surface is firstly powder coated to form a primer layer having a specific color, and when the primer layer is formed and dried completely, a secondarily transparent upper surface layer, that is, a surface protective layer is formed for the primer layer Various colors can be implemented.
여기에서, 분체도장이란 보통 에폭시 또는 폴리에틸렌계 분말을 원료로 하여 금속 표면에 정전기를 이용하여 도장하는 방법으로 기존 용제형(액체페인트) 보다 내식성, 접착성, 내구성 등이 월등히 뛰어나고 특히 부식방지에 효과적이며 고품질의 표면균일성을 갖는 제품을 만드는데 널리 쓰이는 도장방법이다.Here, the powder coating is a method of applying static electricity to the metal surface using epoxy or polyethylene powder as a raw material, which is superior in corrosion resistance, adhesion and durability to conventional solvent type (liquid paint), and is particularly effective in preventing corrosion Is a widely used coating method for making products with high quality surface uniformity.
이러한 분체도장중 가장 널리 쓰이는 방법으로는 코로나 정전스프레이법으로서, 본 발명에서도 이 방법을 통해 분체도장된다.The most widely used method among such powder coatings is a corona electrostatic spraying method, which is also powder coated by this method in the present invention.
코로나 정전스프레이법은 고전압 하에서 음(-)으로 대전된 분체를 접지된 피도물(금속)에 분사하여 전기적으로 부착시킨 후 가열 용해하여 도막화시키는 방법으로, 한번 부착된 분체도료는 일반적으로 전기저항이 높아 방전하기 어렵기 때문에 세팅중에 피도물에서 떨어지는 경우가 없으며, 또한 분체도료는 어느 정도의 두께로 부착되면 분체끼리 서로 크게 반발하게 되어 그 이상의 두께로는 부착하지 않게 되는 성질을 가지고 있는 이를 정전평형 현상이라고 부르며, 이 현상에 의해 피도물의 도막 두께를 균일하게 할 수 있다.The corona electrostatic spray method is a method of spraying a negatively charged powder on a grounded substrate (metal) under high voltage, electrically adhering it, and dissolving it by heating to dissolve the coating film. The powder coating once attached generally has high electrical resistance The powder coating does not fall off from the substrate during the setting because it is difficult to discharge, and when the powder coating is attached to a certain thickness, the powder repels each other largely, This makes it possible to make the thickness of the coating film uniform.
이와 같은 분체도장 방식을 응용한 본 발명에 따른 하도층은 분체도료를 코로나 정전스프레이법을 통해 형성된다.The undercoat layer according to the present invention applying the powder coating method is formed by corona electrostatic spraying method.
이때, 분체도료는 비스페놀 A형 에폭시수지 분체 40-50중량%, 경화제 10-12중량%, 안료 2-4중량%, 보수조절제 2.5-5.5중량%, 세라믹 분말 0.5-1.5중량%, 스티렌 모노머 5-10중량% 및 나머지 필러(Filler)로 이루어진다.At this time, the powder coating material is composed of 40 to 50% by weight of a bisphenol A type epoxy resin powder, 10 to 12% by weight of a curing agent, 2 to 4% by weight of a pigment, 2.5 to 5.5% by weight of a repairing agent, 0.5 to 1.5% by weight of a ceramic powder, -10% by weight and the rest of the filler.
이 경우, 상기 에폭시수지 분체는 당량이 500-600g/eq인 비스페놀 A형을 사용하는 것이 바람직한데, 이는 에폭시수지의 당량을 600g/eq 이하로 낮춰 내화학성을 높이고, 용융점도를 낮춰 도막의 기계적 강도를 높이기 위함이며, 500g/eq 미만이 되면 도막의 표면이 거칠어지므로 상기 범위로 한정해야 한다.In this case, the epoxy resin powder is preferably a bisphenol A type having an equivalent weight of 500-600 g / eq. This is because when the equivalent weight of the epoxy resin is lowered to 600 g / eq or less, the chemical resistance is improved and the melt viscosity is lowered, If it is less than 500 g / eq, the surface of the coating film becomes rough. Therefore, it should be limited to the above range.
또한, 상기 경화제는 지방족 아민인 디시안디아민이 바람직하다. 디시안아민은 강도 및 전기적 특성과 내열성, 상대안정성이 뛰어나 도막(하도층)의 부착안정성을 강화시킨다.The curing agent is preferably dicyandiamine, which is an aliphatic amine. Dicyanamine is excellent in strength and electrical properties, heat resistance and relative stability, and enhances adhesion stability of the coating film (undercoat layer).
그리고, 상기 안료는 다양한 색상 구현을 위한 것으로, 이를 테면 비스무트 바나데이트, 카본 블랙, 네이비 블루, 시아닌 그린, 산화 철황 등 다양한 것이 사용될 수 있다.The above-mentioned pigments are used for various colors, such as bismuth vanadate, carbon black, navy blue, cyanine green, and iron oxide yellow.
뿐만 아니라, 상기 보수조절제는 도장면에서의 도장액(분체도료가 용융분사되어 표면에서 경화되기 전 상태)의 보수성을 증대시키기 위한 것으로, 이때 보수성이란 도장액 내 수분의 이동에 대한 도장액의 저항력을 말한다.In addition, the repairing agent is intended to enhance the water retention of the coating liquid (state before the powder coating liquid is melted and sprayed on the surface) on the coated surface, wherein the water retention property refers to the resistance of the coating liquid to the movement of water in the coating liquid .
이를 위해, 본 발명에서는 상기 보수조절제로 카르복시메틸 셀룰로오스 염을 사용한다. 이 경우, 카르복시메틸 셀룰로오스 염은 목재펄프로부터 유도된 섬유소 유도체인 셀룰로오스를 가성소다에 침적시켜 알카리 셀룰로오스를 만든 다음 이것을 다시 빙초산과 반응시켜 카르복시메틸 셀룰로오스 염 형태로 만든 것으로 보수성이 탁월하여 본 발명에서 사용된다.For this purpose, the carboxymethyl cellulose salt is used as the maintenance agent in the present invention. In this case, the carboxymethyl cellulose salt is prepared by immersing cellulose, which is a cellulose derivative derived from wood pulp, into caustic soda to make an alkali cellulose, and then reacting it with glacial acetic acid to form a carboxymethyl cellulose salt form. do.
아울러, 상기 세라믹 분말은 고온 안정성을 증대시키고, 경도를 높이기 위해 첨가된다.In addition, the ceramic powder is added to increase the high-temperature stability and to increase the hardness.
또한, 상기 스티렌 모노머는 도막의 가교밀도를 높여 내충격성과 내찰과성을 증대시시키 위해 첨가된다. 다만, 10중량%를 초과하면 황변현상이 나타나 내후성이 떨어질 수 있으므로 주의하여야 하며, 5중량% 미만으로 첨가되면 내충격성과 내찰과성 효과를 얻을 수 없으므로 상기 범위로 한정해야 한다.Further, the styrene monomer is added to increase the crosslinking density of the coating film to increase impact resistance and abrasion resistance. However, if it exceeds 10% by weight, yellowing phenomenon may occur and weatherability may be lowered. It should be noted that addition of less than 5% by weight can not provide impact resistance and abrasion resistance.
그리고, 상기 필러(Filler)는 도막의 치수안정성을 높이면서 도막의 물성 저하를 막기 위한 충전제로서, 티타늄 옥사이드가 바람직하다.The filler is preferably a titanium oxide as a filler for preventing the deterioration of the physical properties of the coating film while improving the dimensional stability of the coating film.
이에 더하여, 도막의 접착력과 무기물간의 결합력을 증대시키기 위해 폴리아크릴 아마이드(Polyacrylamide)를 상기 분체도료 100중량부에 대해 4-8중량부 더 첨가하고, 도막의 표면장력을 높이고 유분을 제거하여 도막 안정화를 강화시키도록 글리세릴스테아레이트(Glyceryl Stearate)를 상기 분체도료 100중량부에 대해 2.5-4.5중량부 더 첨가하며, 물과 접촉시 극미량씩 용출되면서 표면에 때가 끼는 것을 막아 표면 세정력을 높이도록 천연알카리제인 세스키탄산나트륨(Na2CO3ㆍNaHCO3ㆍ2H2O)을 상기 분체도료 100중량부에 대해 3-6중량부 더 첨가할 수 있다. In addition, in order to increase the adhesion of the coating film and the bonding force between the inorganic materials, polyacrylamide is added in an amount of 4-8 parts by weight based on 100 parts by weight of the powder coating, and the surface tension of the coating film is increased, And 2.5-4.5 parts by weight of glyceryl stearate is added to 100 parts by weight of the above powder coating material.
