Description
본 발명은 케이블용 난연 도료 조성물에 관한 것으로서, 보다 상세하게는, 수성계 수지, 난연제, 및 안료를 이용하여 통신구내의 화재시에 케이블의 전소를 방지하거나 지연시키는 비발포 수성계 난연 도료 조성물에 관한 것이다.The present invention relates to a flame retardant coating composition for cables, and more particularly, to a non-foaming aqueous flame retardant coating composition that uses an aqueous resin, a flame retardant, and a pigment to prevent or delay burnout of a cable during a fire in a communication port. It is about.
전력, 통신, 및 제어용 케이블의 사용은 지난 20년간 기하급수적으로 증가하고 있는 실정이며, 케이블 시설의 대형화, 과밀화, 지하화됨에 따라 화재가 발생하게 되면 화재의 진압이 어려워져 화재가 시스템 및 주변 전체에 파급되어 인명 및 재산피해를 줄 뿐만 아니라 경제, 정보통신의 전반에 걸쳐 손실을 주게 되어 심각한 사회문제가 발생한다. The use of power, communication, and control cables has increased exponentially over the last two decades, and as the size, overcrowding, and underground of cable facilities increase, it is difficult to extinguish the fires, making it difficult to extinguish the fire. Not only does it spill over and damage people and property, but it also damages the economy and information and communication, causing serious social problems.
이러한 케이블을 화재로부터 보호하는 전선케이블용 방화도료 조성물의 종래기술로서, 대한민국 공개특허 제10-1996-0001058호(1996.01.25)에는 '세라믹 화이버를 이용한 전선케이블 방화도료 조성물 및 제조방법'이 개시되어 있다. 이에 따른 도료 조성물은 세라믹 화이버, 산화일루미나, 산화규소, 및 유기첨가제로 이루 어진다.As a prior art of wire coating fire protection composition for protecting such cable from fire, Korean Patent Publication No. 10-1996-0001058 (1996.01.25) discloses 'wire cable fireproof coating composition and manufacturing method using a ceramic fiber' It is. The coating composition accordingly consists of ceramic fibers, alumina oxide, silicon oxide, and an organic additive.
이 밖에 난연 도료 조성물은 사용 성분에 따라 수성형과 유성형으로 구분되며 도막의 탄화층 형성에 따라 발포형과 비발포형으로 나눈다.In addition, the flame retardant coating composition is divided into an aqueous type and an oil type according to the component used, and is divided into a foam type and a non-foam type according to the formation of the carbonized layer of the coating film.
일반적으로 발포형 도료는 난연성은 양호하나 수분에는 약한 단점이 있는데 특히, 지하 공동구의 다습한 환경에 의해, 도장 후에 도막의 부풀음 현상과 함께 크랙이 발생하고 물이 닿으면 도막이 쉽게 녹아 내림에 따라 박리 현상이 나타난다.In general, foamed paint has good flame retardancy but has a weak disadvantage in moisture. Especially, due to the humid environment of the underground cavity, cracks occur with the swelling of the coating film after coating, and when the water touches, the coating film easily melts and peels off. The phenomenon appears.
따라서 이러한 현상을 보완하기 위해 2~3년마다 상도(TOP COATING)를 재도장하여 성능을 보완하게 되어 있으나 실제적으로 도막의 부분적 탈락 등으로 인해 상도의 재도장이 어려운 상태이며, 이러한 상태에서는 화재 시 필요한 난연 성능을 나타내지 못하여 피해를 볼 수 있다.Therefore, to remedy this phenomenon, the top coating is repainted every two to three years to compensate for the performance, but it is difficult to repaint the coating due to partial dropout of the coating. Failure to show the required flame retardant performance can result in damage.
이러한 원인은 화재 시 탄화층을 형성하여 난연성을 부여하는 탄화제, 산촉매제, 발포제 등이 내수성에 약하여 도장을 한 후 시간이 지나 도료의 도막이 건조되어도 수분에 의해 쉽게 용해되어 도막의 물성을 저하시키기 때문이다.This is because carbonization, acid catalyst, foaming agent, etc., which give a flame retardancy by forming a carbonized layer in case of fire, are weak in water resistance and are easily dissolved by moisture even after the coating is dried over time, thereby deteriorating the physical properties of the coating. Because.
이러한 발포형 도료 조성물의 종래기술로서, 대한민국 공개특허 제10-2005-0070812호(2005.07.07)에는 '수성계 발포성 방염도료 조성물'이 개시되어 있다. 이에 따른 도료 조성물은 수성계 수지, 발포제, 촉매, 탄화제, 보강제, 안료, 첨가제, 및 물로 이루어진다.As a prior art of such a foam coating composition, Republic of Korea Patent Publication No. 10-2005-0070812 (2005.07.07) discloses 'aqueous foaming flame retardant coating composition'. The coating composition accordingly consists of an aqueous resin, a blowing agent, a catalyst, a carbonizing agent, a reinforcing agent, a pigment, an additive, and water.
한편, 비발포형 도료는 발포형 도료보다 내수성은 양호하나 일반적으로 브롬과 같은 할로겐계의 난연제를 사용하여 화재 시 할로겐 가스를 발생시켜 장비에 치명적인 영향을 줄 뿐만 아니라 인체에도 유해하기 때문에 종래에는 비할로겐 난연제를 사용하였다. On the other hand, non-foamable paints have better water resistance than foamed paints, but in general, halogen-based flame retardants such as bromine are used to generate halogen gas in the event of fire, which not only has a fatal effect on the equipment but also is harmful to humans. Halogen flame retardants were used.
이러한 비할로겐계 난연제의 종래기술로서, 대한민국 등록특허 제10-0446558호(2004.08.23)에는 '비할로겐계 무기화합물 난연제 조성물'이 개시되어 있다. 이에 따른 난연제 조성물은 인, 알루미늄, 및 알루미늄 포스페이트로 이루어진다.As a conventional technology of such a non-halogen-based flame retardant, Korean Patent No. 10-0446558 (2004.08.23) discloses a 'non-halogen-based inorganic compound flame retardant composition'. The flame retardant composition thus consists of phosphorus, aluminum, and aluminum phosphate.
한편, 유성타입의 난연 도료는 상기와 같은 내수성이 어느 정도 보완되었으나, 지하 공동구와 같은 밀폐된 장소에 도장 시에는 용제 증발에 따른 휘발성 유기화합물 방출에 의하여 인체에 치명적인 손상을 입힐 수 있다. On the other hand, the oil-based flame retardant paint is somewhat compensated for the above water resistance, but when painted in a closed place, such as underground hollow spheres may cause fatal damage to the human body by volatile organic compounds released by evaporation of the solvent.
이러한 휘발성 유기화합물을 최소화한 것이 수성 타입의 난연 도료인데 일반적으로 내수성이 약하여 지하 공동구와 같은 항상 다습 곳에는 쉽게 부풀어 오르거나 크랙의 발생으로 도막의 박리 현상이 나타난다. The type of water-based flame retardant paint that minimizes these volatile organic compounds is generally poor in water resistance, so that it always swells easily at high humidity places such as underground cavity, or peeling of the coating film occurs due to cracks.
또한, 케이블의 재질은 PVC인데 상기 PVC 소재에 대한 접착력이 떨어지고 케이블의 특성상 휘어졌을 때 도막이 깨지지 말아야 하고 부착력이 양호해야 하나 이것 또한 불량하게 나타난다. In addition, the material of the cable is PVC, but the adhesion to the PVC material is inferior when the film is bent due to the characteristics of the cable should not be broken and the adhesion should be good, but this also appears poor.
따라서 내수성이 양호하고 PVC에 접착력과 굴곡성이 우수한 비할로겐 수성계 난연도료 조성물을 제공하여 지하 공동구에 설치되는 케이블에 도포하여 화재 시 화재의 확산을 방지하거나 지연시키는 도료 조성물의 개발이 요구되고 있다.Therefore, there is a demand for the development of a coating composition which provides a non-halogen water-based flame retardant coating composition having good water resistance and excellent adhesion and bending property to PVC and applied to a cable installed in an underground cavity to prevent or delay the spread of fire in the event of a fire.

이하 본 발명의 케이블용 수성계 난연 도료 조성물을 보다 상세하게 설명한다.Hereinafter, the aqueous flame retardant coating composition for cables of the present invention will be described in more detail.
상기 케이블은 전력케이블, 통신케이블, 및 제어용 케이블 등이 이용될 수 있다.As the cable, a power cable, a communication cable, a control cable, or the like can be used.
본 발명의 도료 조성물은 수성계 수지, 무기계 난연제, 체질 안료, 특수 안료, 첨가제, 및 물로 이루어진다.The coating composition of the present invention consists of an aqueous resin, an inorganic flame retardant, an extender pigment, a special pigment, an additive, and water.
수성계 수지는 우레탄 에멀젼수지(Urethane emulsion resin), 에틸렌 비닐 아세테이트 에멀젼수지(Ethylene vinyl acetate emulsion resin), 아크릴 실리콘 에멀젼수지(Acryl silicon emulsion resin), 아크릴 에멀젼수지(Acryl emulsion resin), 포타슘실리케이트 무기계 수지(Potassium silicate resin) 중에서 선택된 하나 또는 2종 이상의 수성계 수지를 사용하며, 상기 수성계 수지는 내약품성, 내 후성, 유연성 등의 내구성이 양호하고 뛰어난 내수성을 발휘한다.Aqueous resins include urethane emulsion resins, ethylene vinyl acetate emulsion resins, acrylic silicon emulsion resins, acrylic emulsion resins, and potassium silicate inorganic resins. (Potassium silicate resin) using one or two or more types of water-based resin, the water-based resin is excellent in durability, such as chemical resistance, weather resistance, flexibility and excellent water resistance.
또한, 수성계 수지는 지하 공동구와 같은 다습한 곳에서 건조가 잘되며 건조 후에도 습기에 의한 도막의 크랙 및 박리 현상이 없고 PVC재질로 이루어진 케이블 내면에 도장시 접착력이 양호하며, 굴곡성이 우수하다.In addition, the water-based resin is well dried in a humid place such as underground cavity, there is no crack and peeling phenomenon of the coating film even after drying, the adhesive strength is good when coating on the inner surface of the cable made of PVC material, it is excellent in flexibility.
이러한 수성계 수지의 유리전이 온도는 -5℃ 내지 30℃이고 도막 형성온도는 0℃ 내지 25℃이다.The glass transition temperature of such aqueous resin is -5 degreeC-30 degreeC, and coating-film formation temperature is 0 degreeC-25 degreeC.
수성계 수지의 함량은 전체 난연 도료 조성물에 대하여 20 중량부 내지 40 중량부인 것이 바람직하며, 수성계 수지의 함량이 20 중량부 미만인 경우에는 내수성, 굴곡성, 및 접착력이 불량해지며, 수성계 수지의 함량이 40 중량부 초과인 경우에는 난연 성능이 떨어진다.The content of the water-based resin is preferably 20 parts by weight to 40 parts by weight based on the total flame retardant coating composition. When the content of the water-based resin is less than 20 parts by weight, water resistance, flexibility, and adhesion are poor, and If the content is more than 40 parts by weight, flame retardant performance is poor.
난연제는, 연소시 인산, 염소, 및 브롬을 포함한 독성 가스와 다이옥신을 발생하고 내열성이 약한 유기계 난연제 대신에, 연소시 물, 이산화탄소, 및 아황산가스와 같은 불연성 기체를 방출하는 무기계 난연제를 이용한다.Flame retardants use inorganic flame retardants that generate toxic gases, including phosphoric acid, chlorine, and bromine, upon combustion, and non-combustible gases such as water, carbon dioxide, and sulfurous acid gases, when burned, instead of organic flame retardants that generate dioxins and have low heat resistance.
무기계 난연제로는 수산화알루미늄(Aluminium hydroxide), 수산화마그네슘(Magnesium hydroxide), 산화세륨(Cerium Oxide), 산화안티몬(Antimony oxide), 산화규소(Silicon oxide), 주석산 아연(Tartaric acid zinc), 몰리브덴산염(Molybdates), 구아니딘계 화합물, 및 지르코늄(Zirconium) 중에서 선택된 하나 또는 2종 이상의 무기계 난연제를 사용한다.Inorganic flame retardants include aluminum hydroxide, magnesium hydroxide, cerium oxide, antimony oxide, silicon oxide, tartaric acid zinc, and molybdate One or two or more inorganic flame retardants selected from Molybdates), guanidine-based compounds, and zirconium.
무기계 난연제는 연소시 불활성 기체에 의해 가연성 기체가 희석되고 무기화합물이 열에 의해 분해되면서 발생되는 부산물이 수지와 반응을 일으켜 수지의 표 면에 막을 형성함으로써 연소에 필요한 산소의 접근을 막는 역할과 함께 흡열반응에 의해 소재의 냉각 및 열분해 생성물의 생성을 감소시키며, 고온에서 안정성을 갖는다.Inorganic flame retardants are endothermic with the role of preventing the access of oxygen necessary for combustion by forming a film on the surface of the resin by reacting with the resin by-products generated when the flammable gas is diluted by inert gas and the inorganic compound is decomposed by heat. The reaction reduces the cooling of the workpiece and the production of pyrolysis products and is stable at high temperatures.
무기계 난연제의 함량은 전체 난연 도료 조성물에 대하여 3 중량부 내지 20 중량부인 것이 바람직하며, 무기계 난연제의 함량이 3 중량부 미만인 경우에는 난연 성능이 저하되며, 무기계 난연제의 함량이 20 중량부 초과인 경우에는 유동성의 저하로 인하여 작업성이 떨어지고 굴곡성이 불량해진다.The content of the inorganic flame retardant is preferably 3 parts by weight to 20 parts by weight based on the total flame retardant coating composition, when the content of the inorganic flame retardant is less than 3 parts by weight, the flame retardant performance is lowered, and the content of the inorganic flame retardant is greater than 20 parts by weight. Due to the deterioration in fluidity, the workability is poor and the flexibility is poor.
체질안료는 탄산칼슘(Calcium carbonate), 크레이(Clay), 카오린(Kaoline), 황산바륨(Barium sulfate), 활석(Talc), 규조토(Diatomaceous earth), 및 이산화티탄(Titanium dioxide) 중에서 하나 또는 2종 이상의 체질안료를 사용하여 우수한 내마모성, 저장성, 및 작업성을 가진다.Sieving pigments are one or two of calcium carbonate, cray, kaoline, barium sulfate, talc, diatomaceous earth, and titanium dioxide. The above extender pigments have excellent wear resistance, shelf life and workability.
체질안료의 함량은 전체 난연 도료 조성물에 대하여 20 중량부 내지 35 중량부인 것이 바람직하며, 체질안료의 함량이 20 중량부 미만인 경우에는 은폐력이 떨어지고, 체질안료의 함량이 35 중량부 초과인 경우에는 내수성이 저하되며, 접착력, 작업성, 및 굴곡성이 불량해진다.The content of the extender pigment is preferably 20 parts by weight to 35 parts by weight with respect to the total flame retardant paint composition. When the content of the extender pigment is less than 20 parts by weight, the hiding power is lowered, and when the content of the extender pigment is more than 35 parts by weight, water resistance. This decreases, and the adhesion, workability and flexibility are poor.
특수안료는 벤토나이트(Bentonite), 퍼라이트(Perlite), 및 실리카(Silicon dioxide) 중에서 선택된 하나 또는 2종 이상의 특수안료를 사용하여 지하 공동구와 같은 다습한 곳에 도료 조성물을 도장하여도 물방울에 의해 도막이 흘러내리는 것을 방지한다. Special pigments use one or two or more special pigments selected from Bentonite, Perlite, and Silica dioxide, so that the coating film may flow down by water droplets even when the paint composition is painted in a humid place such as an underground cavity. To prevent them.
특수안료의 함량은 전체 난연 도료 조성물에 대하여 1 중량부 내지 10 중량 부인 것이 바람직하며, 특수안료의 함량이 1 중량부 미만인 경우에는 도료 조성물이 다습한 곳에서 건조된 후에 물방울이 맺히면서 흘러내리고, 특수안료의 함량이 10 중량부 초과인 경우에는 작업성이 불량해진다.The content of the special pigment is preferably 1 part by weight to 10 parts by weight with respect to the total flame retardant paint composition, when the content of the special pigment is less than 1 part by weight, the coating composition is dried in a humid place and then flows down as water droplets form. When the content of the special pigment is more than 10 parts by weight, workability is poor.
첨가제로는 냉동안정제, 분산제, 습윤제 등이 최적의 도료 및 도막 성능을 발휘하도록 적정비율로 혼합되어 있으며, 첨가제의 함량은 전체 난연 도료 조성물에 대하여 0.1 중량부 내지 10 중량부인 것이 바람직하다.As the additive, a freeze stabilizer, a dispersant, a humectant, and the like are mixed in an appropriate ratio so as to exhibit an optimum paint and coating performance, and the content of the additive is preferably 0.1 parts by weight to 10 parts by weight based on the total flame retardant coating composition.
물은 도료의 안정한 상태를 유지시켜주고 도장작업을 원활하게 하기 위하여 사용되며 전체 난연 도료 조성물에 대하여 25 중량부 내지 35 중량부인 것이 바람직하다.Water is used to maintain a stable state of the paint and to facilitate the painting work, and preferably 25 parts to 35 parts by weight based on the total flame retardant coating composition.
물의 함량이 25 중량부 미만인 경우에는 도장작업이 매우 어려우며, 물의 함량이 35 중량부 초과인 경우에는 도료 중의 고형분들이 침강하여 굳어지게 되며 요변성이 떨어지게 되어 도장작업시 도료가 흘러내려 원하는 외관 및 건조도막두께를 얻기가 힘들다.If the water content is less than 25 parts by weight, painting is very difficult. If the water content is more than 35 parts by weight, solids in the paint settle and harden. Difficult to obtain film thickness.
