Description
본 발명은 친환경 방오코팅제 조성물에 관한 것으로, 특히 선박, 항만시설, 부표, 교량, 양식장 시설물 등 수중구조물 표면에 코팅하여 수생생물의 부착, 성장을 방지하되, 고가인 상온경화형 실리콘 고무의 사용량을 줄이면서 방오 효과는 극대화시킬 수 있는 친환경 방오코팅제 조성물에 관한 것이다.
The present invention relates to an eco-friendly antifouling coating composition, and more particularly to an eco-friendly antifouling coating composition which is coated on the surface of an underwater structure such as ships, port facilities, buoys, bridges and farm facilities to prevent adhesion and growth of aquatic organisms, And an anti-fouling coating composition capable of maximizing the antifouling effect.
상온경화형 실리콘 고무(Room Temperature Vulcanizable Silicone Rubber)는 다양한 분야에서 접착의 용도로 많이 사용되어 왔다.Room Temperature Vulcanizable Silicone Rubber has been widely used for various applications.
이러한 상온경화형 실리콘 고무의 주된 결합은 Si-O-Si 무기결합으로 구성되어 있으며, 동시에 Si는 알킬기와 결합된 구조를 하고 있기 때문에 C-C 결합으로 구성된 다른 유기계 고무와는 대단히 다른 성질을 보인다. The main bond of this room-temperature-curable silicone rubber is composed of Si-O-Si inorganic bonds, and Si has a very different structure from other organic rubber composed of C-C bonds because it has a structure bonded with an alkyl group.
즉, 상온경화형 실리콘 고무는 고무와 같은 탄성이 있으면서, -70 ~ 200℃ 온도에서 사용 가능하고, 전기절연성과 아크성 등 전기적 성질과 내후성 등이 다른 유기계 고무에 비해 우수하다.That is, the room temperature curing type silicone rubber has elasticity like rubber and can be used at a temperature of -70 to 200 캜, and electrical properties such as electrical insulation and arc resistance and weather resistance are superior to other organic rubber.
예컨대, 액상 실리콘 고무는 축합 2성분형이 1951년 전반에 개발되었고, 이어서 1951년 후반에는 축합 1성분으로 초산형이 개발되었으며, 1960년대 전반에는 부가형인 2성분형이 개발되었다. For example, a liquid silicone rubber was developed in the first half of 1951 with a condensed two-component type, followed by a condensate one-component acetic acid type in the late 1951, and in the early 1960s, a two-component type was developed.
이후, 축합 1성분형인 옥심, 알코올, 아미노옥시형 등이 지속적으로 개발되어 액상 실리콘 고무의 틀을 갖춰지게 되었다. Since then, condensed one-component oximes, alcohols, aminooxy forms, and the like have been continuously developed to provide a liquid silicone rubber frame.
상온경화형 실리콘 고무는 기계적 성질이 비교적 약한 것 외에는 고무로서 요구되는 대부분의 특성이 우수하고, 시공 및 가공이 용이하기 때문에 건축, 토목, 전기, 전자, 자동차, 사무용기기, 항공, 우주산업 등 응용분야가 매우 넓다.The room temperature curing type silicone rubber is excellent in most of the properties required as a rubber other than a relatively low mechanical property and can be easily applied and processed so that it can be used in various fields such as construction, civil engineering, electric, electronic, automobile, office equipment, Is very wide.
한편, 선박이나 교량에서 물과 접촉하는 부분의 표면에는 따개비, 멍게, 홍합, 파래, 굴, 물이끼 등과 같은 수생생물이 부착하여 성장하게 되어 여러 가지 문제점이 발생한다. On the other hand, aquatic organisms such as barnacles, mangoes, mussels, parasites, oysters, and water moss are adhered to the surfaces of the parts in contact with water in ships or bridges, resulting in various problems.
예를 들어, 선박에 수생생물이 부착하게 되면 운행 중 물과의 마찰력이 높아져 연료소비량이 증가되며, 교량 등과 같은 수중구조물에 부착하면 표면이 침식될 수 있고, 양식장 그물에 부착될 경우 그물이 막혀 어류가 대량으로 사망할 수 있는 문제점이 있다.For example, when an aquatic organism attaches to a ship, friction with water increases and fuel consumption increases. When attached to an underwater structure such as a bridge, the surface can be eroded. When attached to a fish farm net, There is a problem that fish can die in large quantities.
이에, 선박이나 수중구조물에 수생생물의 부착과 성장을 방지하기 위한 방안으로 유기주석화합물, 아산화구리 등 환경을 오염시키는 방오제를 배합한 도료를 도장하였지만, 도료의 제조, 도장시 환경과 인해에 유해하고, 특히 유기주석과 아산화구리가 수중에서 서서히 용출되는 메카니즘에 의해 방오기능이 발휘되기 때문에 장기적으로는 바다나 하천이 오염되기 때문에 유기주석화합물은 법적으로 사용이 금지되었으며, 아산화구리도 세계적으로 사용을 금지하는 추세이다.In order to prevent adherence and growth of aquatic organisms on vessels and underwater structures, coatings containing antifouling agents, which contaminate the environment, such as organotin compounds and copper oxide, were applied. However, Organic tin compounds are prohibited from legal use because they are harmful and especially the organic tin and copper oxide elute slowly out of the water due to their antifouling function. It is a trend to ban use.
반면, 상온경화형 실리콘 고무는 독성이 없는 코팅제로 도막의 표면장력을 낮추어 수생생물의 부착과 성장 방지에 효과가 있다. On the other hand, room temperature curing type silicone rubber is a non-toxic coating agent, which is effective in lowering the surface tension of coating film and preventing adherence and growth of aquatic organisms.
관련 선행기술로, 일본 공개특허 소58-13673호와 소62-84166호에는 상온경화형 실리콘 고무에 유동파라핀 또는 바세린을 배합하여 무독성 방오도료를 제조하는 방법이 제안되어 있다.Japanese Patent Application Laid-Open Nos. 58-13673 and 62-84166 disclose a method for preparing a non-toxic antifouling paint by blending liquid paraffin or vaseline with a room temperature curable silicone rubber.
그러나, 상온경화형 실리콘 고무는 대전이 잘되는 성질을 가지고 있기 때문에 대기 중의 먼지나 오염물질이 쉽게 부착되어 코팅 표면이 심각하게 더러워지며, 또한 가격이 고가이므로 아산화구리를 사용한 도료에 비해 경제적인 접근이 어렵다는 문제점이 있다.However, since the room temperature curing type silicone rubber has a good charging property, dust or contaminants in the air easily adhere to the coating surface and the coating surface becomes seriously dirty. Moreover, since the price is high, the economical approach is difficult compared with the coating using the copper oxide There is a problem.
다른 예로, 국내 등록특허 제0407414호, 등록특허 제0526262호 등도 개시되어 있다.As another example, Korean Patent Registration No. 0407414 and Registration No. 0526262 are also disclosed.
그런데, 상기 국내 특허의 경우 방오제와 무관한 것으로, 전자는 접착제 혹은 부착용에 관한 것이고, 후자는 착색제 혹은 도료에 관한 것이다.However, in the case of the above-mentioned domestic patents, the former is irrelevant to the antifouling agent, the latter relates to an adhesive or an adhesive, and the latter relates to a colorant or a paint.
특히, 전자에 개시된 상온경화형 실리콘 고무의 문제로 높은 점도와 그것에 의해 발생되는 기포로 인한 물성 저하 문제 때문에 사용범위가 상당히 제한적임이 나타나 있다.
Particularly, it has been shown that the range of use is very limited due to the problem of the room temperature curing type silicone rubber disclosed in the former, due to the high viscosity and the lowering of the physical properties due to the bubbles generated thereby.
본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점을 감안하여 이를 해결하고자 창출된 것으로, 특히 용제에 희석하여 사용함으로써 상온경화형 실리콘 고무가 갖는 높은 점도 문제를 해결하면서 사용량도 줄일 수 있고, 코팅면에서의 도막 두께도 얇게 할 수 있을 뿐만 아니라, 경화속도도 높이고, 코팅제끼리 뭉치고 퍼지는 현상까지 억제하여 방오성을 극대화시킬 수 있도록 한 친환경 방오코팅제 조성물을 제공함에 그 주된 목적이 있다.
The present invention has been made in view of the above-mentioned problems in the prior art as described above, and is aimed at solving the problems. Particularly, the silicone rubber of the present invention is diluted with a solvent to solve the high viscosity problem of the room temperature curing type silicone rubber, The present invention provides an eco-friendly antifouling coating composition which is capable of minimizing the thickness of the coating layer of the antifouling coating composition, increasing the curing rate, suppressing the spreading and spreading of the coatings, and maximizing the antifouling property.
본 발명은 상기한 목적을 달성하기 위한 수단으로, 친환경 방오코팅제 조성물에 있어서; 상온경화형 실리콘 고무: 3-80중량%; 다이클로로다이메틸실란(Dichlorodimethylsilane): 0.1-5중량% 및 나머지 톨루엔;으로 조성하되, 상기 상온경화형 실리콘 고무는 900-1100 cps의 점도를 갖는 알코올형을 사용하는 것을 특징으로 하는 친환경 방오코팅제 조성물을 제공한다.

이하에서는, 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, preferred embodiments according to the present invention will be described in detail.
본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.
또한, 본 발명의 개념에 따른 실시예는 다양한 변경을 가할 수 있고 여러 가지 형태를 가질 수 있으므로, 특정 실시예들은 도면에 예시하고 본 명세서에 상세하게 설명하고자 한다. 그러나, 이는 본 발명의 개념에 따른 실시예들을 특정한 개시 형태에 한정하려는 것이 아니며, 본 발명의 사상 및 기술 범위에 포함되는 모든 변경물, 균등물 내지 대체물을 포함하는 것으로 이해되어야 한다.In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
본 발명에 따른 상온경화형 실리콘 고무는 환경친화적이며 방오성이 우수하지만, 비교적 고가이므로 수중구조물에 대단위로 적용하기에 어려움이 있다. The room temperature curing type silicone rubber according to the present invention is environmentally friendly and excellent in antifouling property, but it is relatively expensive and thus it is difficult to apply it to a large number of underwater structures.
그러나, 상온경화형 실리콘 고무의 사용량을 줄이기 위해 용제로 희석비율을 높여 코팅하게 되면 도막의 두께가 얇게 되고 경화속도도 빨라져 유리하다.However, in order to reduce the amount of the room temperature curing type silicone rubber, coating by increasing the dilution ratio with a solvent is advantageous because the thickness of the coating film is thinned and the curing speed is also increased.
다만, 도막의 두께가 얇아짐으로 인해 코팅시 코팅제끼리 뭉쳐 퍼짐성이 현저히 저하되는 문제점이 생길 수 있는데, 본 발명에서는 이런 문제점을 염화메틸실란, 특히 강한 소수성을 가진 다이클로로다이메틸실란(Dichlorodimethylsilane)을 일정량 첨가하여 방오기능을 향상시키면서 코팅제끼리의 뭉침 현상을 극복하도록 하였다.However, since the thickness of the coating film is thinned, the coating agent may be aggregated between the coatings during coating, resulting in a significant decrease in spreadability. In the present invention, this problem is solved by using methylsilane chloride, especially dichlorodimethylsilane having strong hydrophobicity And added with a certain amount to improve the antifouling function and overcome the aggregation phenomenon between the coatings.
즉, 본 발명의 개념을 정리하자면, 본 발명은 상온경화형 실리콘 고무를 용제로 희석한 후, 여기에 염화메틸실란, 바람직하게는 다이클로로다이메틸실란((CH2)2SiCl2)을 일정량 사용함으로써 상온경화형 실리콘 고무의 사용량을 최소화하면서 수생생물에 대한 방오 효과가 우수한 친환경 코팅제를 제조할 수 있도록 한 것이다.That is, to summarize the concept of the present invention, the present invention is characterized in that a room temperature curing type silicone rubber is diluted with a solvent, and then methylsilane chloride, preferably dichlorodimethylsilane ((CH 2 ) 2 SiCl 2 ) Thereby making it possible to manufacture an environmentally friendly coating agent having an excellent antifouling effect on aquatic organisms while minimizing the amount of the room temperature curing type silicone rubber.
보다 구체적으로, 본 발명에 따른 친환경 방오코팅제 조성물은 중량%로, 상온경화형 실리콘 고무 3-80%, 다이클로로다이메틸실란(Dichlorodimethylsilane) 0.1-5% 및 나머지 용제로 조성된다.More specifically, the environmentally friendly antifouling coating composition according to the present invention is composed of 3-80% of room temperature curable silicone rubber, 0.1-5% of dichlorodimethylsilane, and the rest of the solvent.
이때, 상기 상온경화형 실리콘 고무는 다이클로로다이메틸실란을 가수분해하여 올리고머(Oligomer) 형태의 다이메틸폴리실록산을 만들고, 이 올리고머에 일정량의 물과 촉매를 넣고 중합시켜 생고무를 만든 다음, 여기에 충전제와 가황제 및 기타 첨가물을 넣고 가열하면서 교반(Milling)하여 제조된다.At this time, the room temperature curing type silicone rubber hydrolyzes dichlorodimethylsilane to form dimethylpolysiloxane in the form of oligomer, and a predetermined amount of water and a catalyst are added to the oligomer to prepare a raw rubber. Then, Adding a vulcanizing agent and other additives, and heating and agitating the mixture.
이러한 상온경화형 실리콘 고무는 공기 중의 수분과 반응하여 경화되는 과정 중에 발생하는 성분에 따라 다음 표 1과 같이 분류할 수 있다.These room temperature curable silicone rubbers can be classified as shown in Table 1 according to components generated during the process of curing by reacting with water in the air.
상기 표 1의 설명에 따르면, 설명된 여러 종류 중 탈알코올형이 수분에 의해 경화되면서 배출되는 물질이 알코올이므로 환경이나 인체에 대한 유해성이 가장 최소화할 수 있음을 확인할 수 있다.According to the description of Table 1, it can be confirmed that the harmfulness to the environment and human body can be minimized because the alcohol is cured by the moisture and the alcohol is the substance discharged from the alcohol.
따라서, 본 발명에서는 탈알코올형 상온경화형 실리콘 고무를 사용하는 것이 가장 좋다.Therefore, in the present invention, it is best to use a dealkanol type room temperature curing type silicone rubber.
또한, 상기 탈알코올형 상온경화형 실리콘 고무의 경우에도 점도가 900-1100 cps 범위를 사용하는 것이, 고점도에 따라 야기될 수 있는 기포문제를 해결할 수 있으며, 특히 바람직하기로는 1000 cps가 좋다.Also, in the case of the above-mentioned de-alcohol type room temperature curing type silicone rubber, the viscosity of 900-1100 cps can be used to solve the problem of air bubbles which can be caused by the high viscosity, particularly preferably 1000 cps.
뿐만 아니라, 본 발명에서 상온경화형 실리콘 고무를 3중량% 미만으로 첨가할 경우, 점착성이 떨어져 코팅작업이 어렵고, 80중량%를 초과하게 되면 점도가 너무 높아져 비용이 많이 들고, 기포 생성에 따른 물성 저하를 초래하며 방오성도 낮아지므로 상기 범위로 한정하여야 한다.In addition, when the room temperature curing type silicone rubber is added in an amount of less than 3% by weight in the present invention, the coating operation is difficult due to the poor tackiness, and when it exceeds 80% by weight, the viscosity becomes too high, And the antifouling property is also lowered.
그리고, 상기 다이클로로다이메틸실란은 상온경화형 실리콘 고무를 제조하는 출발물질로 사용되기 때문에 상온경화형 실리콘 고무와의 혼합과 친화성이 매우 좋다. Since the dichlorodimethylsilane is used as a starting material for preparing a room-temperature-curable silicone rubber, its compatibility with the room temperature curable silicone rubber is very good.
또한, 상온경화성 실리콘 고무는 수분과 반응하여 경화되면 강한 소수성을 보이는데, 상기 다이클로로다이메틸실란도 전기음성도가 불소(F) 다음으로 큰 염소 원자 2개가 있어 매우 강한 소수성을 보인다.The room temperature curable silicone rubber shows strong hydrophobicity when cured by reacting with moisture, and the dichlorodimethylsilane also has very high hydrophobicity due to the presence of two chlorine atoms next to fluorine (F) in electronegativity.
본 발명에서는 물에 의한 가수분해 속도 차이를 줄여 상온경화형 실리콘 고무와의 결합을 균일하게 하고, 이를 통해 내열성 및 유연성을 향상시키며, 궁극적으로는 방오성을 극대화시키기 위해 상기 다이클로로다이메틸실란을 첨가한다.In the present invention, the dichlorodiimethylsilane is added in order to reduce the difference in the rate of hydrolysis by water to make the bonding with the room temperature curable silicone rubber uniform, thereby improving heat resistance and flexibility, and ultimately maximizing the antifouling property .
다만, 과량 첨가되면 결합성 및 반응성에 있어 문제가 야기되므로 0.1-5중량%의 범위 내에서만 첨가하여야 한다.However, if it is added in an excessive amount, it will cause problems in bonding and reactivity, so it should be added within the range of 0.1-5 wt%.
아울러, 용제는 이들 상온경화형 실리콘 고무와 다이클로로다이메틸실란을 제외한 나머지 성분으로 첨가되는 것으로, 희석화를 위해 첨가된다. In addition, the solvent is added for dilution, added to these components except for the room-temperature-curable silicone rubber and dichlorodimethylsilane.
바람직한 용제로는 톨루엔이 있다.A preferred solvent is toluene.
다만, 탈알코올형 상온경화형 실리콘 고무 원액을 희석하여 사용할 때에는 톨루엔이 가장 적합하다. 그 외에 일반적으로 시중에 판매중인 신나를 사용하면 점도가 상승하여 사용할 수 없게 되기 때문에 조심하여야 한다.However, toluene is most suitable when diluted with a stock solution of a tertiary alcohol-type room temperature curable silicone rubber. In addition, when using thinner which is generally sold on the market, it is necessary to be careful because viscosity increases and it becomes unusable.
이하, 실시예에 대하여 설명한다.Hereinafter, examples will be described.
본 발명에 따른 방오코팅제 조성물의 특성을 확인하기 위해, 하기와 같이 본 발명 범주를 벗어난 비교예와, 본 발명 범주 내의 발명예를 각각 만들고, 실험예와 같은 조건에서 평가하였다.In order to confirm the characteristics of the antifouling coating composition according to the present invention, comparative examples out of the scope of the present invention and inventive examples within the scope of the present invention were made as described below, and evaluated under the same conditions as in the experimental examples.
