Description

수성계 발포성 방염도료 조성물{Antiflaming paints composition}Aqueous foamable flame retardant paint composition

본 발명은 발포성 방염도료 조성물 및 그 용도에 관한 것으로서, 나무, 합판 등 가연성 재료에 도포하여 방염성능을 발휘할 수 있는 비할로겐, 수성계 발포성 방염도료 조성물 및 이를 도포한 원목, 합판, 섬유판, 중밀도섬유판, 가구, 광물면 보드, 콘크리트, 철강 및 목재에 관한 것이다.The present invention relates to a foamable flame retardant paint composition and its use, non-halogen, water-based foamable flame retardant coating composition and wood, plywood, fiberboard, medium density coated with the same, which can be applied to combustible materials such as wood, plywood to exhibit flame retardant performance It relates to fiberboard, furniture, mineral wool boards, concrete, steel and wood.

방염도료는 엄격히 말하면 좁게는 건축물을 화재로부터 보호하여 재산의 손실을 방지한다는 기능으로부터 더 넓게는 화재의 확산 방지로 인한 인명의 보호에 그 목적이 있다. 다시 말해 담뱃불 또는 전기 및 석유 난방기구 등으로 인하여 화재 발생시 내장재로 사용되는 원목이나 합판 등의 나무재가 고온의 열 및 불꽃으로부터 발화되어 화염이 전파되는 것을 차단하거나 지연시켜 물질적 손실을 최소화하고 또한 인명을 구조할 수 있는 시간을 제공하는 데 그 목적이 있다.Flame-retardant paints are strictly for the purpose of protecting people from the spread of fire from the function of narrowly protecting buildings from fire to prevent property loss. In other words, wood or plywood, which are used as interior materials in case of fire due to cigarettes or electric and petroleum heaters, is ignited from high-temperature heat and flames, preventing or delaying the propagation of flames, minimizing material loss and reducing human life. The purpose is to provide time to rescue.

특히, 생활의 질적 향상으로 인한 숙박시설, 공공시설, 영업시설 및 유흥시설 등이 증가함에 따라 재산 및 인명을 보호하기 위해서는 시설물의 가연성 내장재에 대한 방염처리는 필수적이다. 방염처리란 시설물의 가연성 내장재 표면에 방염도료 등으로 도포하여 화재발생시 고온의 열 및 불꽃으로부터 가연성 내장재가 발화되어 화염이 전파되는 것을 차단하거나 지연시키는 것을 말한다. In particular, as property, public facilities, business facilities, and entertainment facilities increase due to the improvement of quality of life, it is necessary to flameproof the combustible interior materials of facilities to protect property and life. Flame retardant treatment is applied to the surface of the combustible interior material of the facility with a flame retardant paint, etc. to prevent or delay the propagation of the flame by ignition of the combustible interior material from the heat and flame of high temperature in the event of fire.

가연성 내장재의 방염처리를 위한 방염도료로 그동안 염화고무계 유성 방염도료가 많이 사용되어져 왔으나 유성계 도료는 환경오염의 문제점이 있으며 또한 사람이 항상 상주하는 실내의 내장재에 도장시 장시간에 걸친 유해물질의 배출로 인하여 알레르기를 유발한다는 의학 보고서가 점차로 증가하고 있는 추세로 볼 때 환경친화적인 방염도료에 대한 기대가 점차적으로 높아지고 있다.As a flame retardant paint for flame retardant treatment of flammable interior materials, chlorinated rubber oil-based flame retardant paints have been used for many years. However, oil-based paints have a problem of environmental pollution and discharge of harmful substances for a long time when painting on interior materials where people always reside. As medical reports of allergens are increasing, the expectation for environmentally friendly flame retardant paints is gradually increasing.

수성계 발포성 방염도료는 열에 노출되면 건조도막층이 발포하여 탄화층을 형성하는 도료로서, 이 탄화층이 가연성 피도물(나무 등)을 화염 및 연소열로부터 보호한다. 탄화층 자체는 최종적으로 연소되지만, 연소될 때까지는 어느 정도 시간이 걸리므로 피도체가 받는 영향은 작게 된다.An aqueous foamable flame retardant paint is a paint in which a dry coating layer foams when exposed to heat to form a carbonized layer. The carbonized layer protects flammable coatings (wood, etc.) from flame and combustion heat. The carbonized layer itself is finally combusted, but it takes some time to combust, so the influence of the subject becomes small.

일반적으로 유성계 발포성 방염도료의 조성물에는 염소화된 물질을 혼합함으로써 방염성능의 향상을 도모하고 있으며 이러한 종류의 물질들은 환경오염, 특히 오존층 파괴의 주요물질로 분류됨에 따라 점차적으로 사용이 규제되어지고 있으며 최종적으로는 사용금지 될 것으로 예상된다.In general, oil-based foamed flame retardant paints are formulated to improve the flame retardant performance by mixing chlorinated materials, and these types of materials are gradually regulated as they are classified as main pollutants for environmental pollution, especially ozone layer destruction. Finally, it is expected to be banned.

또한 염소화된 물질을 발포성 방염도료에 사용할 경우 화재 등에 의한 연소시에 발생되는 가스는 상당한 독성 및 부식성이 있으며 따라서 화재시 인체에 매우 유해하다는 것이다. In addition, when the chlorinated material is used in a foamed flame retardant paint, the gas generated during combustion by a fire or the like is quite toxic and corrosive, and therefore is very harmful to a human body in a fire.

그리고 유성계 발포성 방염도료는 유성계 수지와 용제를 주성분으로 하여 제조되어진 도료로서 현장시공시 발생하는 휘발성 유기용제의 환경오염 문제가 있으며 또한 환기조건이 불량한 상태에서의 시공시에는 이러한 휘발성 유기용제가 호흡을 통하여 작업자의 건강을 해치는 동시에 자연발생적인 정전기 또는 실수에 의한 불꽃에 의하여 화재가 발생하여 치명적인 악영향을 줄 수 있다는 것이다. In addition, oil-based effervescent flame-retardant paints are mainly made of oil-based resins and solvents, and there is a problem of environmental pollution of volatile organic solvents generated during field construction, and when volatile organic solvents are applied under poor ventilation conditions. Through breathing, the worker's health can be harmed, and a fire can be caused by a naturally occurring static electricity or a spark by a mistake, which can have a fatal adverse effect.

따라서 유기용제의 사용으로 인한 환경오염 및 작업조건불량의 문제를 해결하기 위해서는 휘발성 유기용제를 물로 대체한 수성계 발포성 방염도료를 사용해야 하며 이는 전세계적으로 환경오염문제로 인하여 휘발성 유기물질의 규제가 강화되고 있는 추세로 볼 때 필수적인 일이라 할 수 있다.Therefore, in order to solve the problem of environmental pollution and working conditions caused by the use of organic solvents, water-based foamed flame retardant paints having replaced volatile organic solvents with water should be used. The trend is becoming essential.

대한민국 특허공개 제95-26952호 및 특허공고 제92-6763호에는 국제특허공개 제94-701430호 등에는 염화고무, 염화파라핀(염소함유량 70%, 40%) 등 모두 할로겐 화합물인 염소 화합물을 사용하고 있는 바, 이를 이용하여 발포성을 부여하여 방염성능을 발휘하는 것이나 이러한 할로겐 화합물질을 발포성 방염도료에 사용할 경우 화재 등에 의한 연소시에 발생되는 가스는 상당한 독성 및 부식성이 있으며 따라서 화재시 인체에 매우 유해하다는 단점이 있었다. Korea Patent Publication No. 95-26952 and Patent Publication No. 92-6763 use chlorine compounds that are all halogen compounds such as rubber chloride and chlorinated paraffin (chlorine content 70%, 40%) for International Patent Publication No. 94-701430, etc. In this case, the foaming property is used to give a flame retardant performance. However, when the halogenated compound is used in a foamed flame retardant paint, the gas generated during combustion due to a fire is extremely toxic and corrosive. There was a disadvantage of being harmful.

본 발명은 상기와 같은 문제점을 해결하기 위하여 염소화된 물질을 사용하지 않고, 유성계 수지와 유기용제를 수성계 수지와 물로 대체하여 환경오염 및 작업환경의 문제가 없는 발포성이 뛰어난 수성계 발포성 방염도료를 제공하는데 그 목적이 있다.The present invention does not use chlorinated materials to solve the above problems, and replaces oil-based resins and organic solvents with water-based resins and water, water-based foamable flame retardant paint excellent in foamability without problems of environmental pollution and working environment The purpose is to provide.

본 발명의 또 다른 목적은 상기와 같은 방염도료를 도포하여 방염성을 부여하는 방법을 제공하는 데도 있다.Still another object of the present invention is to provide a method of applying flame retardant coating as described above to impart flame retardancy.

상기와 같은 목적을 달성하기 위한 본 발명의 수성계 발포성 방염도료는 알킬변성 비닐아세테이트 공중합체인 수성계 수지 5∼35중량%, 발포제 5∼25중량%, 촉매 13∼45중량%, 탄화제 5∼25중량%, 보강제 0.1∼7중량%, 안료 3∼20중량%, 첨가제 3∼15중량% 및 물 20∼50중량%로 조성되는 것임을 그 특징으로 한다. The aqueous foamable flame retardant paint of the present invention for achieving the above object is 5 to 35% by weight of an aqueous resin, which is an alkyl-modified vinyl acetate copolymer, 5 to 25% by weight of a blowing agent, 13 to 45% by weight of a catalyst, and 5 to 5 carbonizing agents. It is characterized by being composed of 25% by weight, 0.1 to 7% by weight of reinforcing agent, 3 to 20% by weight of pigment, 3 to 15% by weight of additive, and 20 to 50% by weight of water.

이와같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.

본 발명의 비할로겐, 수성계 발포성 방염도료를 구성하는 조성물들은 구체적으로 다음과 같다.Compositions constituting the non-halogen, water-based foaming paint of the present invention are specifically as follows.

우선, 수지는 건조경화도막이 상온에서는 내구성을 발휘하고 고온의 열에 노출되었을 때는 도막을 유동상태로 변화시켜 가스가 발생될 때 적절하게 도막이 발포될 수 있는 역할을 수행하게 된다. 이러한 수지는 알킬변성 비닐아세테이트 공중합체인 수성계 에멀젼으로 내약품성, 내후성, 유연성 등 내구성이 양호하고, 특히 뛰어난 내수성을 발휘하며 유리전이온도가 -30∼60℃의 범위이며 도막형성온도는 0∼30℃의 범위를 갖는 수성계 수지이다. First of all, the resin exhibits durability at room temperature, and when exposed to high temperature heat, changes the coating into a fluid state so that the coating film can be properly foamed when gas is generated. These resins are aqueous emulsions of alkyl-modified vinyl acetate copolymers, which have good durability, such as chemical resistance, weather resistance, and flexibility, and exhibit particularly excellent water resistance. The glass transition temperature is in the range of -30 to 60 ° C and the film forming temperature is 0 to 30. It is an aqueous resin having a range of ° C.

수성계 수지의 함량은 전체 도료 조성 중 5∼35중량%이며, 만일 수지의 함량이 전체 조성물 중 5중량% 미만이면 건조경화도막의 내구성이 불량해지며 35중량% 초과면 발포율이 떨어지고 발포중간에 도막이 박리되어 정상적인 방염성능을 발휘할 수 없게 되어 바람직하지 않다. The water-based resin content is 5 to 35% by weight of the total coating composition, and if the resin content is less than 5% by weight of the total composition, the durability of the dry hardened coating film becomes poor. It is not preferable because the coating film is peeled off so that normal flame retardant performance cannot be exhibited.

발포제는 고온에서 분해되어 탄화제 및 촉매와 반응하여 탄화층을 형성하며 반응 중에 가스를 발생시켜 탄화층이 적절하게 발포할 수 있도록 하는 역할을 수행하게 된다. 이러한 발포제로는 멜라민(melamine), 디시안디아마이드(dicyandiamide), 우레아(urea), 글리신(glycine) 등이 있다.The blowing agent decomposes at a high temperature to react with the carbonizing agent and the catalyst to form a carbonized layer and generates a gas during the reaction to serve to allow the carbonized layer to foam properly. Such blowing agents include melamine, dicyandiamide, urea, glycine, and the like.

발포제의 함량은 전체 도료 조성 중 5∼25중량%이며, 만일 발포제의 함량이 전체 조성물 중 5중량% 미만이면 탄화층 형성이 불량해지며 발생되는 가스도 불충분하여 탄화층의 발포가 미약하며 25중량% 초과면 가스의 발생이 너무 많아지게 되어 탄화층의 발포 이전에 가스의 과량 분출로 인하여 탄화층이 갈라져 정상적인 방염성능을 발휘할 수 없게 되어 바람직하지 않다. The content of the blowing agent is 5 to 25% by weight of the total paint composition. If the content of the blowing agent is less than 5% by weight of the total composition, the formation of the carbonized layer is poor and the gas generated is insufficient, so that the foaming of the carbonized layer is weak and 25% by weight. If it is more than%, the gas is generated too much, and the carbonized layer is cracked due to excessive ejection of the gas before foaming of the carbonized layer, and thus it is not preferable to exhibit normal flame retardant performance.

그리고, 촉매는 고온에서 분해되어 가스를 방출하면서 탄화제 및 발포제의 반응을 촉진시키고 동시에 반응에 참여하여 탄화층을 형성하는 역할을 수행하게 된다. 이러한 촉매로는 1급 암모늄 포스페이트(primary ammonium phosphate), 2급 암모늄 포스페이트(secondary ammonium phosphate), 암모늄 포스파이트(ammonium phosphite), 암모늄 폴리포스페이트(ammonium polyphosphate), 멜라민 포스페이트(melamine phosphate), 디멜라민포스페이트(dimelamine phosphate), 멜라민 피로포스페이트(melamine pyrophosphate) 및 트리크레실 포스페이트(Tricresyl Phosphate) 등이 있다.In addition, the catalyst decomposes at a high temperature to promote the reaction of the carbonizing agent and the blowing agent while releasing the gas and at the same time participates in the reaction to form a carbonized layer. Such catalysts include primary ammonium phosphate, secondary ammonium phosphate, ammonium phosphite, ammonium polyphosphate, melamine phosphate, and dimelamine phosphate. (dimelamine phosphate), melamine pyrophosphate and tricresyl phosphate.

이와 같은 촉매의 함량은 13∼45중량%이며, 만일 발포제의 함량이 전체 조성물 중 13중량% 미만이면 탄화제 및 발포제와의 반응이 원활하지 못하게 되고 45중량% 초과면 오히려 발포율이 떨어져 방염성능이 저하되므로 바람직하지 않다. The catalyst content is 13 to 45% by weight. If the content of the blowing agent is less than 13% by weight of the total composition, the reaction with the carbonizing agent and the blowing agent is not smooth. It is not preferable because it is lowered.

탄화제는 고온에서 발포제와 반응을 하여 방염성능을 발휘하는 탄화층을 형성시키는 역할을 한다. 이러한 탄화제로는 펜타에리트리톨(pentaerythritol), 디펜타에리트리톨(dipentaerythritol), 트리펜타에리트리톨(tripentaerythritol), 소르비톨(sorbitol), 트리메틸올프로판(trimethylolpropane), 트리메틸올에탄(trimethylolethane), 디트리메틸올프로판(ditrimethylolpropane) 등이 있다. The carbonizing agent reacts with the blowing agent at a high temperature to form a carbonized layer that exhibits flame retardant performance. Such carbonizing agents include pentaerythritol, dipentaerythritol, tripentaerythritol, pentitolerythritol, sorbitol, trimethylolpropane, trimethylolpropane and ditrimethylolpropane. (ditrimethylolpropane).

탄화제의 함량은 5∼25중량%이며, 만일 탄화제의 함량이 전체 조성물 중 5중량% 미만이면 발포제와의 화학반응이 불충분하여 적합한 탄화층 형성이 어려워지며 25중량% 초과면 발포율이 떨어져 방염성능이 저하되므로 바람직하지 않다. The content of carbonizing agent is 5 to 25% by weight. If the content of carbonizing agent is less than 5% by weight of the total composition, the chemical reaction with the blowing agent is insufficient, making it difficult to form a suitable carbonized layer. It is not preferable because the flame retardant performance is lowered.

보강제는 건조경화도막이 고온에서 발포되어 탄화층을 가지는 발포도막으로 형성되었을 때 탄화층의 강도를 증가시켜 주위의 화염 등으로부터 발포도막이 박리되거나 부분적으로 날리는 현상을 방지하여 방염성능을 향상시키는 역할을 한다. 이러한 보강제로는 삼산화 몰리브덴, 이산화 지르코늄, 수산화 알루미늄 등 금속산화물 및 금속수화물, 아연 보레이트 등 금속화합물, 유리분말, 규소계 안료 등 무기물 등이 있다. The reinforcing agent increases the strength of the carbonized layer when the dry hardened film is foamed at a high temperature to form a carbonized layer, thereby improving the flame retardant performance by preventing the foamed film from peeling off or partially blowing away from the surrounding flame. . Such reinforcing agents include metal oxides such as molybdenum trioxide, zirconium dioxide, aluminum hydroxide, metal compounds such as metal hydrates, zinc borate, inorganic materials such as glass powder, and silicon pigments.

보강제의 함량은 0.1∼7중량%이며, 만일 보강제의 함량이 0.1중량% 미만이면 발포층의 강도부여 효과가 미약하며 7중량% 초과면 탄화층의 강도가 너무 단단해져 가스발생시 탄화층이 갈라지며 또한 발포율을 현저히 감소시키게 되어 방염성능이 매우 불량해지게 되므로 바람직하지 않다. The content of the reinforcing agent is 0.1 to 7% by weight. If the content of the reinforcing agent is less than 0.1% by weight, the effect of strengthening the strength of the foamed layer is insignificant. If the content of the reinforcing agent is more than 7% by weight, the carbonized layer is so hard that the carbonized layer cracks when gas is generated. It is not preferable because the foaming rate is significantly reduced and the flame retardant performance becomes very poor.

안료의 함량은 3∼20중량%이며, 만일 안료의 함량이 전체 조성물 중 3중량% 미만이면 착색력이 부족하며 또한 발포과정에서 발포도막 내부에 균일한 기공층의 형성이 어려워 단열성능이 떨어지게 되며 20중량% 초과면 발포율이 불량해 방염성능이 저하되므로 바람직하지 않다. The pigment content is 3 to 20% by weight. If the pigment content is less than 3% by weight of the total composition, the coloring power is insufficient, and it is difficult to form a uniform pore layer inside the foam coating during the foaming process. If the content is more than% by weight, the foaming rate is poor and the flame retardant performance is lowered, which is not preferable.

첨가제로서 동결방지제, 융합제, 증점제, 분산제, 소포제, 방부제 및 pH 조절제 등이 최적의 도료 및 도막성능을 발휘하도록 적정비율로 혼합되어 있으며 첨가제는 전체 조성물 중 3∼15중량%를 사용한다.As an additive, a cryoprotectant, a fusion agent, a thickener, a dispersant, an antifoaming agent, a preservative, and a pH adjusting agent are mixed at an appropriate ratio to achieve optimal paint and coating performance, and the additive is used in an amount of 3 to 15% by weight in the total composition.

물은 도료의 안정한 상태를 유지시켜주고 도장작업성을 원활하게 하기 위하여 사용되어지며 전체 조성물 중 20중량% 미만이면 도장작업이 매우 어려우며 50중량% 초과면 도료 중의 고형분들이 침강하여 굳어지게 되며 또한 요변성(搖變性)이 떨어지게 되어 도장작업시 도료가 흘러내려 원하는 외관 및 건조도막두께를 얻기가 매우 힘들어진다. 물의 함량은 전체 조성물의 총중량을 기준으로 20∼50중량%이다. Water is used to maintain the stable state of paint and to improve the painting workability. If it is less than 20% by weight of the total composition, the painting work is very difficult. If it is more than 50% by weight, solids in the paint settle and harden. It is hard to obtain the desired appearance and dry film thickness because paints flow down during painting work due to degeneration. The water content is 20-50% by weight based on the total weight of the total composition.

한편, 상기와 같은 조성을 갖는 본 발명의 비할로겐, 수성계 발포성 방염도료의 발포과정을 기술적으로 서술하면 다음과 같다. On the other hand, if the technical description of the foaming process of the non-halogen, water-based foamable flame retardant paint of the present invention having the composition as described above are as follows.

발포 1단계Foaming Stage 1

건조도막 면에 화재 발생 등에 의하여 열이 가해져 유기성분(특히 수성계 수지 등)의 연화점 이상이 되면 도막은 유동 상태로 전환된다. 이 상태는 도막이 발포를 시작하기에 적합한 상태로 준비되어 있음을 의미한다.When heat is applied to the dry coating surface due to a fire or the like, the coating film is converted into a fluid state when the organic component (particularly, an aqueous resin or the like) is equal to or more than the softening point. This state means that the coating film is prepared in a state suitable for starting foaming.

발포 2단계Foaming Stage 2

도막의 온도가 상승함에 따라 촉매, 발포제 및 탄화제와 그 외 유기성분들이 분해되면서 여러 가지 가스를 방출하게 된다. 이 때 방출되는 가스는 도막 내의 어느 성분으로부터 분해되어 나오는가에 따라 약간씩 다르기는 하지만 대개 수증기, 암모니아, 이산화탄소 등으로, 이들이 유동상태에 있는 수지 등의 성분을 밀고 나오게 됨으로써 자연히 도막내부에 발포층을 형성하면서 도막이 발포되기 시작한다.As the temperature of the coating rises, the catalyst, blowing agent and carbonizing agent and other organic components decompose and release various gases. Although the gas released varies slightly depending on which component in the coating film is decomposed, it is usually water vapor, ammonia, carbon dioxide, etc., and they push out components such as resin in a flow state, thereby naturally forming a foam layer in the coating film. As it forms, the coating film starts to foam.

발포 3단계Foaming Stage 3

도막의 발포가 계속되면서 동시에 발포도막의 표면층은 탄화가 되기 시작한다. 초기에는 팽창과 탄화가 동시에 진행되지만 시간이 지남에 따라 탄화되는 부분이 많아지면서 도막의 팽창도 서서히 둔화되어 어느 시간이 경과하면 더 이상 발포되지 않고 탄화만 진행되게 된다. 이렇게 형성되는 발포층의 두께는 초기 건조 도막 두께의 50-150배가 되며, 발포의 결과로 탄화층의 밀도는 최초도막보다 낮아진다.As the foaming continues, the surface layer of the foamed coating starts to carbonize. Initially, expansion and carbonization proceed simultaneously, but as carbonization increases over time, the expansion of the coating gradually slows down, and after a certain time, only carbonization proceeds without foaming. The thickness of the foam layer thus formed is 50-150 times the initial dry coating thickness, and as a result of the foaming, the density of the carbonized layer is lower than that of the initial coating film.

발포 4단계Four stages of firing

발포층은 최종적으로 전체가 하얗게 될 때까지 계속 탄화가 되어 외부의 열이 피도물까지 전달되는 것을 막는다. The foam layer continues to carbonize until the entire white is finally white, preventing external heat from reaching the workpiece.

상기의 발포과정을 통하여 발포율이 50-150배인 발포도막을 형성하며 부피가 팽창된 발포도막은 화염에 의한 발포도막의 탈락이나 날림이 없고 화염 및 연소열로부터 가연성피도물(나무 등)의 발화 및 열전달을 효과적으로 차단하는 주요한 인자인 것이다.Through the above foaming process, foaming film having foaming rate of 50-150 times is formed and the expanded foamed film has no dropping or blowing off of the foamed coating film by flame, and ignition and heat transfer of flammable coating materials (wood, etc.) from flame and combustion heat. It is a major factor that effectively blocks

본 발명에 따른 방염도료 조성물은 상기와 같이 뛰어난 발포율과 도막강도를 겸비함으로써 적은 양으로서 효율적인 방염효과를 나타낼 수 있다는 것을 알 수 있다. It can be seen that the flame retardant coating composition according to the present invention can exhibit an effective flame retardant effect in a small amount by combining the excellent foaming rate and the coating film strength as described above.

따라서 상기와 같은 각각의 원료들을 최적의 비율로 조절하여 혼합된 비할로겐, 수성계 발포성 방염도료는 실내장식물, 칸막이용 합판 등 많은 사람이 이용하는 숙박시설, 공공시설, 영업시설 및 유흥시설 등의 방염성능이 요구되어지는 곳에 사용될 수 있다.Therefore, non-halogen and water-based foamed flame retardant mixed by controlling each raw material at the optimum ratio is used for flame retardant accommodation, public facilities, business facilities and entertainment facilities used by many people, such as interior decoration and partition plywood. Can be used where performance is required.

특히, 행정자치부고시 제2000-10호 제5조 방염성능의 기준 및 측정기준에 의한 시험방법에 의하여 방염도료로서 적합할 경우 소방법 시행령 제11조 및 대통령령에 의한 특수장소의 방염대상물에 사용이 가능하며 또한 별장 등 목조주택에도 적용가능하다. In particular, if it is suitable as a flame retardant paint according to the test method based on the standard and measurement criteria of flame retardant performance no. It is also applicable to wooden houses such as cottages.

일반적인 발포성 방염도료의 경우 건조경화도막이 화재 등에 의하여 고온의 열에 노출되어 탄화층을 형성하며 발포된 후 계속적으로 고온의 열에 노출될 경우에 이 발포층은 백화되어 강도가 매우 약하게 되며 따라서 화염 등에 의하여 쉽게 박리되거나 날리게 된다.In the case of general foamed flame retardant paints, when the dry-hardened coating film is exposed to high temperature heat by a fire or the like to form a carbonized layer, and if it is continuously exposed to high temperature heat after foaming, the foamed layer becomes white and becomes very weak in strength. Peeling or blowing.

그러나, 본 발명의 비할로겐, 수성계 발포성 내화도료는 보강제가 도료 중에 적정한 비율로 혼합되어 있기 때문에 이 보강제가 상기와 같은 백화층의 강도를 효과적으로 부여하기 때문에 화염 등에 의하여 박리되거나 날리지 않음으로써 방염성능을 지속적으로 장시간동안 유지시켜주게 된다.However, since the non-halogen and water-based foamed refractory paints of the present invention are mixed with the reinforcing agent in an appropriate ratio, the reinforcing agent effectively exerts the strength of the whitening layer as described above, so that it is not peeled off or blown off by a flame or the like. Maintain a long time continuously.

이때, 건조된 피막의 두께는 0.05∼0.50㎜가 바람직하다 At this time, the thickness of the dried film is preferably 0.05 to 0.50 mm.

도장방법은 붓도장, 에어 스프레이도장, 롤러도장 등을 사용할 수 있다. The painting method may be a brush coating, air spray coating, roller coating and the like.
