Abstract
본 발명은 설정된 온도에서 반응하는 캡슐을 활용한 방오도료에 있어서: 수지의 기재에 주 방오제, 보조 방오제, 용제, 안료, 첨가제를 혼합하여 도료를 생성하되, 상기 보조 방오제는 설정된 온도에서 상변화 파손을 유발하는 온도 반응형 셀에 수용되어 캡슐로 형성된다.
이에, 온도 반응형 캡슐을 기반으로 하는 보조 방오제의 배합을 통해 비교적 장기간 선박이 안벽에 계류하는 동안 해수 온도가 상승하는 하절기에 추가적인 방오제를 용출함에 따라, 하절기 해양생물의 부착을 방지하여 품질 문제 및 시운전 시 선속 미확보 위험성을 예방하고, 선체 점검ㆍ세척 주기를 연장하여 연간 선박하부 방오도료 유지ㆍ보수 비용을 경감한다.The present invention relates to an antifouling paint using a capsule that reacts at a set temperature: a resin base material is mixed with a main antifouling agent, an auxiliary antifouling agent, a solvent, a pigment, and an additive to produce a paint, wherein the auxiliary antifouling agent is used at a set temperature. It is housed in a temperature-responsive cell that causes phase change failure and is formed into a capsule.
Accordingly, through the formulation of an auxiliary antifouling agent based on a temperature-responsive capsule, additional antifouling agent is eluted in the summer when the sea temperature rises while the ship is moored at the quay wall for a relatively long period of time, thereby preventing adhesion of marine life in the summer and improving quality. It prevents problems and the risk of not securing ship speed during test runs, and reduces annual maintenance and repair costs for antifouling paint on the bottom of ships by extending the hull inspection and cleaning cycle.
Description
본 발명은 선박의 마찰 저항을 줄이기 위해 해양 생물의 부착을 방지할 목적으로 적용되는 방오도료에 관한 것으로, 더욱 상세하게는 선박 건조 중 안벽 계류 기간 동안 하절기에 집중적으로 발생하는 해양 생물의 부착을 방지할 수 있도록 선박의 수선하부에 임시로 적용하기 위한 온도 반응형 캡슐을 활용한 방오도료에 관한 것이다. The present invention relates to an antifouling paint applied for the purpose of preventing the adhesion of marine life in order to reduce the frictional resistance of ships, and more specifically, to prevent the adhesion of marine life, which occurs intensively in the summer during the mooring period on the quay wall during ship construction. This is about an antifouling paint using a temperature-responsive capsule for temporary application to the lower waterline of a ship.
선박과 해양구조물은 정박 또는 운항 중 항시 수많은 해양 생물과 접촉하고 있다. 일단 해양 생물이 선박에 부착되면 표면의 거칠기가 늘어나므로 선박의 마찰 저항이 증가하고 선속의 저하로 이어진다. 따라서 선박 및 해양구조물의 수선 하부에는 해양 생물의 부착을 방지하고 표면의 거칠기를 완화하여 마찰 저항을 줄일 수 있도록 방오도료를 적용하고 있다.Ships and marine structures are always in contact with numerous marine life while at anchor or in operation. Once marine life attaches to a ship, the roughness of the surface increases, which increases the frictional resistance of the ship and leads to a decrease in ship speed. Therefore, antifouling paints are applied to the lower part of the waterline of ships and marine structures to prevent the adhesion of marine life and reduce frictional resistance by alleviating surface roughness.
이와 관련되는 선행기술문헌의 일예로서, 한국 등록특허공보 제1617725호는 선박의 선체(hull outside) 및 수중 구조물(underwater structure)에 도장하는 도막의 상도(top coat)로서 해양 생물의 부착 및 성장을 방지하기 위해 적용하는 수지 및 방오도료 조성물을 개시한다.As an example of prior art literature related to this, Korean Patent Publication No. 1617725 is a top coat of a coating film applied to the hull outside of a ship and underwater structure to prevent the attachment and growth of marine life. Disclosed are resins and antifouling paint compositions applied to prevent the present invention.
선행기술문헌의 다른 예로서, 한국 등록특허공보 제1725611호에 의하면, 자기 연마성이 손상되지 않고, 해중에서의 우수한 방오 효과가 장기간 지속됨과 함께 내수성이 양호한 방오 도료용 조성물, 방오 도료, 방오 도막이 개시된다.As another example of prior art literature, according to Korean Patent Registration No. 1725611, there is a composition for an antifouling paint, an antifouling paint, and an antifouling coating film that has good water resistance while maintaining excellent antifouling effect in the sea for a long time without damaging self-polishing properties. It begins.
상기 선행기술문헌을 비롯한 종래의 방오도료는 Tin-free SPC 또는 Foul release 타입이 있으며 주로 Tin-free SPC 제품이 많이 적용된다. 이 제품은 해수와의 가수분해 반응에 의해 도막의 외곽 층이 순차적으로 마모되면서 방오제를 용출, 해양생물의 부착을 방지하고 표면을 매끄럽게 유지하는 기능을 부여한다. 그러나 이 타입의 제품은 주방오제의 용출속도, 도막의 마모속도가 도료의 수지 및 안료, 방오제 배합에 따라 설계되어 있으므로 해수와의 접촉 시 정적인 상태에서는 일정 속도로만 방오제의 용출 및 도막의 마모가 구현된다.Conventional antifouling paints, including those in the prior art literature, are of Tin-free SPC or Foul release types, and Tin-free SPC products are mainly applied. This product has the function of preventing the adhesion of marine life and maintaining a smooth surface by eluting the antifouling agent as the outer layer of the coating film is sequentially worn through a hydrolysis reaction with seawater. However, this type of product is designed so that the dissolution rate of major stains and the wear rate of the coating film are based on the resin, pigment, and antifouling agent mix of the paint, so when in contact with seawater, the dissolution of the antifouling agent and the coating film only occurs at a certain rate in a static state. Wear is implemented.
해수 온도가 상승하는 하절기에는 각종 해양 생물의 번식 및 성장 그리고 활성도가 증대되고 이로 인해 선저부에 해양생물의 부착률이 증가하게 된다. 따라서 선박이 안벽에 계류된 상태에서 방오도료의 설계된 방오제 용출속도를 초과할 경우 해양생물의 부착 발생을 초래하게 된다.In the summer, when sea temperatures rise, the reproduction, growth, and activity of various marine organisms increase, which increases the attachment rate of marine organisms to the bottom of the ship. Therefore, if the designed antifouling agent dissolution rate of the antifouling paint is exceeded while the ship is moored at the quay wall, marine organisms may attach to the vessel.
상기와 같은 종래의 문제점들을 개선하기 위한 본 발명의 목적은, 안벽 계류 기간 특히, 하절기에 집중적으로 발생하는 해양생물의 부착을 원천적으로 감소시켜 품질 문제를 예방하고 시운전 시 선속을 확보할 수 있는 온도 반응형 캡슐을 활용한 방오도료를 제공하는 데 있다.The purpose of the present invention to improve the conventional problems described above is to fundamentally reduce the adhesion of marine life, which occurs intensively during the mooring period on the quay wall, especially in the summer, to prevent quality problems and to secure a temperature during test operation.

본 발명에 따른 방오도료에 사용되는 용제는 통상적인 방오도료 조성물에 사용되는 용제 종류에서 제한되지 없으나 자일렌(Xylene) 및 에틸벤젠(Ethylbenzene) 중 적어도 하나를 사용하는 것이 선호된다. 일예로 자일렌(Xylene)의 함량을 에틸벤젠(Ethylbenzene)의 함량의 대략 2배 정도로 유지할 수 있다. 어느 경우에나 사용되는 용제의 함량이 15 중량% 미만이면 도료의 점도가 높아서 도장 작업성을 확보하기 어려우며, 30 중량%을 초과할 경우 도료의 안티 새깅(Anti-sagging)이 저하되며 도장 결함을 초래할 수 있다. The solvent used in the antifouling paint according to the present invention is not limited to the type of solvent used in conventional antifouling paint compositions, but it is preferred to use at least one of xylene and ethylbenzene. For example, the content of xylene can be maintained at approximately twice the content of ethylbenzene. In any case, if the solvent content used is less than 15% by weight, the viscosity of the paint is high, making it difficult to secure painting workability, and if it exceeds 30% by weight, the anti-sagging of the paint is reduced and can lead to painting defects. You can.
