은계 무기향균제를 포함하는 향균수지조성물 {Antibacterial resin composition containing silver-based inorganic antibacterial agent}Antibacterial resin composition containing silver-based inorganic antibacterial agent}

본 발명은 은계 무기향균제를 포함하는 향균수지조성물에 관한 것이다.The present invention relates to an antibacterial resin composition containing a silver-based inorganic antibacterial agent.

농수산물을 양식하거나 이를 가공 및 생산하는 업체는 생산물을 업체의 내부에 보관하거나 양식하는 내부 시설에 보관한다. 이 경우 생산물의 신선도를 유지하기 위하여 각종 유해균으로부터 생산물의 보호가 가장 중요하다.Companies that farm, process, and produce agricultural and marine products store the products inside the company or in internal farming facilities. In this case, protection of the product from various harmful bacteria is most important in order to maintain the freshness of the product.

나아가, 국내의 호수와 하천에는 조류가 과다하게 발생하여 수질이 악화됨으로써 상수원의 수질관리 뿐만 아니라 취수 및 정수 공정의 운전을 어렵게 하고 있다. 조류는 정수 과정에서 탁도를 떨어뜨릴 뿐만 아니라 응접침전의 장애를 일으키고, 여과지를 조기에 폐색시켜 여과지속시간의 단축에 따른 역세척 횟수를 증가시키는 원인의 하나가 되고 있다.Furthermore, excessive algae is generated in domestic lakes and rivers, deteriorating water quality, making it difficult not only to manage the water quality of water sources but also to operate water intake and purification processes. Algae not only reduces turbidity during the water purification process, but also causes problems with sedimentation and clogs the filter paper prematurely, which is one of the causes of shortening the filtration duration and increasing the number of backwashes.

이끼, 조류는 수족관에서 발생한 후 광합성과 호흡을 하며, 일반적으로 C5H8O2N으로 표시되어 탄소(C), 수소(H), 산소(O) 그리고 질소(N) 분자들로 구성된 일종의 유기합성물질과 같다. 이들은 광합성과 호흡으로 끊임없이 CO2를 섭취하고 O2를 발생시켜 수족관의 알칼리도에 영향을 주며 산소의 공급원이기도 하다. 그러나 이들은 빛이 존재하지 않을 때는 광합성 작용없이 용존산소를 섭취하므로 물고기의 생존에 위협이 될 수도 있다. 또 이끼류의수명이 끝나면 이들의 사체로부터 많은 질소화합물이 생성되고 이들의 성장이 극치에 달할 경우에는 녹조 현상이 두드러지게 된다.Moss and algae undergo photosynthesis and respiration after growing in an aquarium, and are generally expressed as C5H8O2N, which is a kind of organic synthetic material composed of carbon (C), hydrogen (H), oxygen (O), and nitrogen (N) molecules. They continuously consume CO2 and generate O2 through photosynthesis and respiration, which affects the alkalinity of the aquarium and is also a source of oxygen. However, when there is no light, they consume dissolved oxygen without photosynthesis, which can pose a threat to the survival of fish. Also, at the end of the life of lichen, many nitrogen compounds are produced from their dead bodies, and when their growth reaches its peak, green algae phenomenon becomes noticeable.

조류는 그 세포의 비중이 낮기 때문에 조류 플럭의 침강성이 저하되거나 재부상되어 침전효율이 떨어지며 또한 조류가 늘어나면 물의 수소이온농도(pH)가 상승하면 응집지에서 응집효율이 떨어져 플럭(floc)의 형성이 떨어지며 조류 세포의 높은 표면전하와 많은 조류 부산물로 인해 응집제 소요량이 늘어난다. 침전지에서 제거되지 못한 조류는 여과지로 넘어가 수두손실을 가져와 여과지속시간을 단축시킨다. 정상 상태에서 여과지 지속시간은 30-100시간 범위이지만 조류가 대량 발생하는 기간에는 10시간 이하로 떨어져 역세척 주기가 짧아지게 된다. 결과적으로 조류의 대발생은 정수효율을 저하시키고 식수원 수질을 악화시키는 주원인이 되고 있다.Because the specific gravity of algae cells is low, the sedimentation efficiency of algae flocs decreases or resurfaces, which reduces sedimentation efficiency. Additionally, as algae increases, the hydrogen ion concentration (pH) of the water increases, and the floc efficiency decreases in the floc. Formation decreases and the amount of coagulant required increases due to the high surface charge of algal cells and the large amount of algal by-products. Algae that cannot be removed from the sedimentation tank flows to the filter, causing head loss and shortening the filtration duration. Under normal conditions, the filter duration is in the range of 30-100 hours, but during periods when large amounts of algae are generated, it falls below 10 hours and the backwash cycle is shortened. As a result, large outbreaks of algae are the main cause of lowering water purification efficiency and deteriorating the quality of drinking water sources.

또한, 가정용 수조, 대형 건물의 물탱크, 산업장의 저수조, 양식장, 수족관, 전시장 등의 경우에도, 흔히 물때라고 하는 이끼류와 조류 등이 벽면에 부착하여 수질을 악화시키고, 어류 양식에도 막대한 피해를 주고 있다.In addition, in the case of household water tanks, water tanks of large buildings, industrial water tanks, fish farms, aquariums, exhibition halls, etc., moss and algae, commonly called scale, adhere to the walls, deteriorating water quality and causing enormous damage to fish farming. there is.

이끼 조류도 유기물이고 산화제를 투입하면 분해될 수 있으나, 이를 제거하기 위한 화학약품의 투입은 물고기의 생명과도 직결되어 문제점이 발생하였다.Moss algae is also an organic matter and can be decomposed by adding an oxidizing agent, but the use of chemicals to remove it is directly related to the life of fish, causing problems.

따라서 심각해지는 상수도 정수장, 가정용 수조, 대형건물의 물탱크, 산업장의 저수조, 양식장, 수족관, 전시장, 상수처리장 등에서 생기는 조류발생 문제에 대해 보다 효율적으로 대처하기 위해서는 기존의 상수처리장 공정을 향상시키고, 저수조 및 양식장의 수질을 향상시키기 위하여 조류 발생을 억제하거나 제거하는 기술개발이 필요하다. 이를 위해서는 기존 공정에 별다른 추가시설 없이 적용할 수 있으면서도 보다 경제적인 기술이 필요하다.Therefore, in order to more efficiently deal with the increasingly serious algae problem occurring in water purification plants, household water tanks, water tanks in large buildings, industrial water storage tanks, fish farms, aquariums, exhibition halls, water treatment plants, etc., existing water treatment plant processes must be improved and water storage tanks must be improved. In order to improve the water quality of fish farms, it is necessary to develop technology to suppress or remove algae. To achieve this, a more economical technology is needed that can be applied to existing processes without any additional facilities.

종래에는 이와 같은 문제를 해결하기 위하여 친수성 유기도료를 도포시켜 사용하여 왔는데 친수성 유기도료는 여러 유기 재료들을 물이나 유기 용매와 혼합시킨 도막 조성물이었다. 그러나 이 유기 재료들은 용매에 대한 분산성이 양호하지 못할 경우 도막 표면이 균일하지 못하고, 유기물질이 용출되어 2차적인 수질공해를 유발할 뿐만 아니라, 접착력과 내수성이 떨어지고, 내구성이 약하여 정기적으로 재시공하여 하는 등의 문제점을 가지고 있었다.Conventionally, in order to solve this problem, hydrophilic organic paints have been applied and used. Hydrophilic organic paints are coating compositions made by mixing various organic materials with water or organic solvents. However, if these organic materials do not have good dispersibility in solvents, the surface of the coating film is not uniform, and organic substances are leached out, causing secondary water pollution, as well as poor adhesion and water resistance, and poor durability, so they must be reapplied regularly. There were problems such as

It has a good dilution effect to control viscosity and is ductile, so it reacts with the hardener to improve overall physical properties. Prevents deterioration of water resistance and durability without change and prevents white clouding from occurring.

부틸 글리시딜 에테르가 5 중량부 미만이면 연성이 발생하지 않고 경도가 높아져 크랙이 발생하는 문제가 있으며, 10 중량부를 초과하면 전체적인 물성변화가 발생하며, 이로 인하여 접착력이 저하되는 문제가 있다.If the amount of butyl glycidyl ether is less than 5 parts by weight, ductility does not occur and hardness increases, causing cracks to occur. If it exceeds 10 parts by weight, the overall physical properties change, which causes a problem of reduced adhesion.

벤질 알코올은 주제부 100 중량부에 대해 1 내지 3 중량부 포함되도록 구비될 수 있다. Benzyl alcohol may be included in an amount of 1 to 3 parts by weight based on 100 parts by weight of the main component.

상기 벤질 알코올은 비반응성 희석제로서, 주제와의 반응에 참여하지 않으면서 저점도, 고유동성을 부여하여, 콘크리트 구조물의 균열에 높은 침투성으로 침투할 수 있도록 하고, 우수한 신장률을 부여하고, 충분한 가사시간을 제공하여 우수한 작업성능을 제공할 수 있는 기능을 한다.The benzyl alcohol is a non-reactive diluent that provides low viscosity and high fluidity without participating in reaction with the main substance, allowing it to penetrate into cracks of concrete structures with high permeability, provides excellent elongation, and provides sufficient pot life. It has the function of providing excellent work performance.

상기 벤질 알코올이 1 중량부 미만으로 구비되는 경우에는 상기한 개선효과가 미흡할 수 있는 문제가 있고, 3 중량부를 초과하는 경우에는 경화속도가 너무 지연되는 문제가 있다.When the amount of benzyl alcohol is less than 1 part by weight, the improvement effect may be insufficient, and when it is more than 3 parts by weight, the curing speed is excessively delayed.

폴리디메틸실록산은 주제부 100 중량부에 대해 1 중량부 이하로 포함되도록 구비될 수 있다.Polydimethylsiloxane may be included in an amount of 1 part by weight or less based on 100 parts by weight of the main component.

폴리디메틸실록산은 수산기를 함유한 실리콘 폴리아크릴레이트 수지이다. 수산기를 함유하고 있어 가교결합에 참여하여 도막물성을 증진시키는 역할을 한다. Polydimethylsiloxane is a silicone polyacrylate resin containing hydroxyl groups. Because it contains hydroxyl groups, it participates in cross-linking and improves the film properties.

상기 폴리디메틸실록산이 1 중량부를 초과하는 경우에는 습기 경화가 원활히 수행되지 않는 문제가 있다.If the amount of polydimethylsiloxane exceeds 1 part by weight, there is a problem in that moisture curing is not performed smoothly.

석회석은 주제부 100중량부에 대해 20 ~ 30 중량부 포함되도록 구비될 수 있다. 상기 석회석은 본 발명의 도료 조성물이 유기물로 구성되어 있어서 강도가 약하고, 특히 여름철과 같이 고온의 온도조건하에서는 도막의 강도가 현저하게 떨어지게 되는 단점이 있다. 상기 석회석은 이러한 유기물에 의한 도막의 강도를 온도 변화 유무에 상관없이 일정하게 유지할 수 있도록 해준다.Limestone may be included in an amount of 20 to 30 parts by weight based on 100 parts by weight of the main body. The limestone has a disadvantage in that the paint composition of the present invention is composed of organic materials, so its strength is weak, and the strength of the paint film is significantly reduced, especially under high temperature conditions such as summer. The limestone allows the strength of the coating film formed by these organic substances to be kept constant regardless of the presence or absence of temperature changes.

또한, 상기 석회석은, 본 발명의 도료 조성물이 유기물질로 구성되어 있는 것이어서, 화재가 발생될 경우, 쉽게 타버리게 되는 단점이 있는데, 이러한 단점을 극복하여 유기물질의 발화성을 방지하고, 도료조성물의 불연성을 부여하기 위하여 사용되어진다.In addition, the limestone has the disadvantage of being easily burned in the event of a fire because the coating composition of the present invention is composed of organic materials. By overcoming this disadvantage, the ignition of organic materials is prevented and the coating composition It is used to provide incombustibility.

상기 석회석이 도료 조성물의 전체 중량에 대해 20 중량부 미만이면, 도막 강도의 향상에 미치는 영향이 미미한 반면, 30 중량 % 초과하면 경우에는 도막의 강도는 높아지지만, 상기 아크릴레이트 공중합체의 성분에 비해 과도한 함유량으로 인하여 크랙 발생의 가능성이 높아지는 문제가 있다.If the amount of limestone is less than 20 parts by weight relative to the total weight of the coating composition, the effect on improving the strength of the coating film is minimal, whereas if it exceeds 30% by weight, the strength of the coating film increases, but compared to the components of the acrylate copolymer, There is a problem that the possibility of cracks occurring increases due to excessive content.

한편, 상기 은계 무기항균제(Silver-base inorganic antimicrobial agent)는 은-제올라이트 항균제 또는 은-지르코늄 항균제로 이루어지거나 이들의 혼합물로 이루어진다. 본 발명은 은계 무기항균제에 의해 항균성을 가진다. Meanwhile, the silver-base inorganic antimicrobial agent consists of a silver-zeolite antimicrobial agent or a silver-zirconium antimicrobial agent, or a mixture thereof. The present invention has antibacterial properties by using a silver-based inorganic antibacterial agent.

일반적으로 유기항균제는 인체에 대한 안정성의 문제를 야기하는 반면 무기항균제는 유기항균제와 달리 인체에 무해한 장점을 가지며, 유기항균제에 비해 지속성이 길고 내성균을 발생시키지 않는 장점을 가진다. 따라서 본 발명은 이러한 장점을 가지는 무기항균제를 사용하되, 특히, 가장 우수한 항균력을 가지는 금속으로 알려진 은이온이 제올라이트, 지르코늄 등의 무기담체에 담지된 은계 무기항균제를 사용함으로써, 인해에 무해하면서도 우수한 항균성이 지속적으로 유지되는 장점을 가진다. In general, organic antibacterial agents cause safety problems for the human body, while inorganic antibacterial agents have the advantage of being harmless to the human body, unlike organic antibacterial agents, and have the advantage of lasting longer and not generating resistant bacteria compared to organic antibacterial agents. Therefore, the present invention uses an inorganic antibacterial agent that has these advantages, and in particular, uses a silver-based inorganic antibacterial agent in which silver ions, known as the metal with the best antibacterial activity, are supported on an inorganic carrier such as zeolite and zirconium, thereby providing harmless and excellent antibacterial properties. This has the advantage of being continuously maintained.

이러한 은계 무기항균제는 주제부 100 중량부에 대해 0.1 ~ 0.3 중량부 포함되도록 구비될 수 있다. 은계 무기항균제가 0.1 중량부 미만이면 소요되는 수준의 항균성을 기대하기 곤란하며, 0.3 중량부를 초과하면 은계 무기항균제의 함량 대비 항균성 상승효과가 미미하므로 경제적인 측면에서 바람직하지 않다. This silver-based inorganic antibacterial agent may be included in an amount of 0.1 to 0.3 parts by weight based on 100 parts by weight of the main body. If the amount of the silver-based inorganic antibacterial agent is less than 0.1 part by weight, it is difficult to expect the required level of antibacterial activity, and if it exceeds 0.3 parts by weight, the synergistic antibacterial effect is minimal compared to the content of the silver-based inorganic antibacterial agent, so it is undesirable from an economic standpoint.

한편, 이러한 주제부에는 물성을 향상시키기 위해 기능성향균수지도료에 통상적으로 사용되는 안료, 자외선 안정제, 개질제, 소포제, 레벨링제, 습윤제, 분산제, 난연제, 산화방지제 등과 같은 첨가제가 통상의 사용범위에서 적절량 추가로 함유될 수 있음은 당연하다. Meanwhile, in this main section, additives such as pigments, ultraviolet stabilizers, modifiers, antifoaming agents, leveling agents, wetting agents, dispersants, flame retardants, antioxidants, etc., which are commonly used in functional antibacterial resin paints to improve physical properties, are appropriate within the range of normal use. It is natural that additional amounts may be contained.

보다 구체적으로, 본 발명의 일 실시예에 따른 경화제부의 폴리옥시프로필렌디아민은 경화제부 100 중량부에 대해 65 ~ 75 중량부 포함되도록 구비될 수 있고, 스타이렌화 페놀은 경화제부 100 중량부에 대해 15 ~ 25 중량부 포함되도록 구비될 수 있으며, 2,4,6-트리스(다이메틸아미노메틸)페놀은 경화제부 100 중량부에 대해 5 ~ 10 중량부 포함되도록 구비될 수 있다.More specifically, the polyoxypropylenediamine in the hardener portion according to an embodiment of the present invention may be included in an amount of 65 to 75 parts by weight based on 100 parts by weight of the hardener portion, and the styrenated phenol may be included in an amount of 15 to 75 parts by weight based on 100 parts by weight of the hardener portion. It may be provided to contain ~25 parts by weight, and 2,4,6-tris(dimethylaminomethyl)phenol may be included in an amount of 5 to 10 parts by weight based on 100 parts by weight of the hardener.

상기 폴리옥시프로필렌디아민은 코팅층의 신율과 인장강도를 조절하고, 수분 안정성과 강도 증가를 위한 성분으로서 그 조성비는 경화제부 100 중량부에 대해 65 ~ 75 중량부 포함되도록 구비될 수 있고, 폴리옥시프로필렌디아민의 함량이 65 중량부 미만이면 신율이 떨어지는 문제가 있고, 폴리옥시프로필렌디아민의 함량이 75 중량부 초과하면 신율과 인장강도는 증가하나 내마모성이 떨어져 내구성 및 수형 저하를 초래하는 문제가 있다.The polyoxypropylene diamine is an ingredient that adjusts the elongation and tensile strength of the coating layer and increases moisture stability and strength. The composition ratio may be 65 to 75 parts by weight based on 100 parts by weight of the hardener, and polyoxypropylene If the diamine content is less than 65 parts by weight, there is a problem of low elongation, and if the polyoxypropylenediamine content exceeds 75 parts by weight, elongation and tensile strength increase, but wear resistance decreases, resulting in durability and deterioration of form.

상기 2,4,6-트리스(다이메틸아미노메틸)페놀은 상기 경화제에 포함되는 2,4,6-트리스(다이메틸아미노메틸)페놀은 속경성을 부여하고, 우수한 충전성, 접착강도, 방수성, 신장률, 내열성, 내화성능 및 내약품성을 부여하는 기능을 한다.The 2,4,6-tris(dimethylaminomethyl)phenol contained in the curing agent provides fast hardening, excellent fillability, adhesive strength, and waterproofing. , it functions to provide elongation, heat resistance, fire resistance, and chemical resistance.

2,4,6-트리스(다이메틸아미노메틸)페놀은 경화제부 100 중량부에 대해 5 ~ 10 중량부 포함하는 것이 바람직하다. 2,4,6-트리스(다이메틸아미노메틸)페놀의 함량이 5 중량부 미만이면, 상기한 개선효과가 미흡할 수 있는 문제점이 있고, 2,4,6-트리스(다이메틸아미노메틸)페놀의 함량이 10 중량부 초과하면, 경화속도가 지나치게 빨라져 작업성이 저하될 수 있는 문제가 있다.It is preferable to include 5 to 10 parts by weight of 2,4,6-tris(dimethylaminomethyl)phenol based on 100 parts by weight of the hardener. If the content of 2,4,6-tris(dimethylaminomethyl)phenol is less than 5 parts by weight, there is a problem that the above-mentioned improvement effect may be insufficient, and 2,4,6-tris(dimethylaminomethyl)phenol If the content exceeds 10 parts by weight, there is a problem that the curing speed becomes too fast and workability may be reduced.
