Abstract
Description
본 발명은 내수성이 우수한 친환경 수성 내화 도료 조성물에 관한 것으로서, 더욱 상세하게는 건축물 등 시공 대상면에 도포되어 화재 발생 시에 화염이나 열에 의해 도료가 발포되도록 하여 피복 대상물이 화염이나 열에 의해 손상되는 것을 방지하도록 하는 내수성이 우수한 친환경 수성 내화 도료 조성물에 관한 것이다.The present invention relates to an environmentally friendly water-resistant fireproof coating composition having excellent water resistance, and more particularly, to be coated on a construction target surface such as a building so that the paint is foamed by flame or heat when a fire occurs so that the coating object is damaged by flame or heat. The present invention relates to an environmentally friendly water-resistant fireproof coating composition having excellent water resistance.
난방을 위한 화기나 전열기구의 사용이 잦고 건조한 겨울은 1년 중 화재 위험이 가장 큰 계절이다. 특히 이번 겨울은 심각한 인명피해를 초래한 대형 화재가 잇따르며 화재 안전에 대한 우려가 커지고 있다.The use of fire or heaters for heating and dry winters is the most dangerous season of the year. This winter, in particular, is accompanied by a large-scale fire that has caused severe casualties, raising concerns about fire safety.
최근 발생한 대형 화재 사고를 살펴보면 화재가 발생한 건물에 사용된 건축자재들이 화재로 인한 피해를 막아주기 보다는 되레 불을 확산시키거나 불길에 유독성 가스를 내뿜으며 피해를 가중하는 역할을 한 것을 알 수 있었다. 이 때문에 내화도료와 같은 불에 강한 내화 건축자재 사용의 필요성이 그 어느 때보다 강조되고 있다.The recent fire accidents showed that the building materials used in the building where the fire occurred did not prevent damage from fire, but rather spread the fire or toxic gas in the flames, causing damage. For this reason, the necessity of using fire-resistant fireproof building materials such as fireproof paint is emphasized more than ever.
내화도료는 건축물의 뼈대인 철골 구조물에 도포하면 화재 발생 시 고온에서 발포하며 철골에 전달되는 열을 차단하는 역할을 하는 일종의 기능성 페인트이다. 철골에 전달되는 열을 차단하는 만큼, 건물 붕괴를 지연시킴으로써 화재로부터 인명과 재산을 보호한다.Refractory paint is a kind of functional paint that serves to block the heat transmitted to the steel frame when it is applied to the steel structure, which is the skeleton of the building, at high temperature when a fire occurs. It protects people and property from fire by delaying the collapse of buildings as it blocks the heat transmitted to steel.
별도 설계나 구조 변경 없이도 이미 지어진 철골 구조 건축물에 활용할 수 있어 철도역사나 공항, 경기장과 같이 철골이 노출된 건축물에 도장만으로 내화성능을 끌어 올릴 수 있다.It can be used for steel structure buildings that have already been built without additional design or structure change, so that the fire resistance performance can be increased by painting only on steel exposed structures such as railway stations, airports, and stadiums.
다양한 색상이나 기타 기능성 페인트도 함께 활용할 수 있으며, 내화기능을 가진 특수 자재 제작 과정을 생략할 수 있어 공기(工期)를 단축시키고, 작업이 용이해 시간이 지난 후에도 유지보수가 수월한 편이다.Various colors and other functional paints can be used together, and the process of making special materials with fire resistance can be omitted, which shortens the air and facilitates the operation, which is easy to maintain after a while.
본 발명의 배경이 되는 기술로는 대한민국 특허등록 제1589060호 "수성계 친환경 및 무독성 발포 방염 내화도료"(특허문헌 1)이 있다. As a background technology of the present invention, there is Korea Patent Registration No. 1589060 "Water-based eco-friendly and non-toxic foaming flame retardant paint" (Patent Document 1).
상기 배경기술에서는 '내화도료에 있어서, 초산비닐수지 100 중량부에 대해 50 ~ 100 mesh 사이즈의 흑연 30~120 중량부, 물 80~120 중량부, 난연제인 붕산아연 10~50 중량부 및 절연제인 이산화티탄늄 1~3 중량부를 혼합하여 이루어지는 것을 특징으로 하는 발포 방염 내화도료'를 제안한다. In the background art, "30 to 120 parts by weight of graphite having a size of 50 to 100 mesh, 80 to 120 parts by weight of water, 10 to 50 parts by weight of zinc borate, which is a flame retardant, and an insulation agent are used in the fireproof paint.

It is effective because it can be applied to a thinner film thickness than existing fire-resistant paints, and it has the effect of reducing cost and shortening the air.It is made of eco-friendly water-based products, and can be installed indoors. An object of the present invention is to provide an environmentally friendly water-resistant fireproof coating composition having excellent water resistance without risk.

아래에서 본 발명은 제시된 실시 예를 참조하여 상세하게 설명이 되지만 제시된 실시 예는 본 발명의 명확한 이해를 위한 예시적인 것으로 본 발명은 이에 제한되지 않는다. Hereinafter, the present invention will be described in detail with reference to the presented embodiments, but the embodiments presented are exemplary for clarity of understanding and the present invention is not limited thereto.
이하 바람직한 실시예에 따라 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention according to a preferred embodiment in detail.
본 발명의 내수성이 우수한 친환경 수성 내화 도료 조성물은 정제수 100중량부를 기준으로, 전색제로 수성 아크릴 에멀젼 수지 70~300중량부와, 착색안료 7~180 중량부와, 촉매제로 암모늄 폴리포스페이트 70~300중량부와, 첨가제 15~70중량부와, 보강제로 수산화 알루미늄 3~70중량부와, 발포제 70~150중량부를 혼합하여 이루어진다.Eco-friendly aqueous fireproof paint composition having excellent water resistance of the present invention is based on 100 parts by weight of purified water, 70 to 300 parts by weight of an aqueous acrylic emulsion resin as a colorant, 7 to 180 parts by weight of pigmented pigment, and 70 to 300 parts by weight of ammonium polyphosphate as a catalyst. It consists of a part, 15-70 weight part of additives, 3-70 weight part of aluminum hydroxides, and 70-150 weight part of foaming agents with a reinforcing agent.
전색제는 상온 조건에서 내구성 및 미장성을 발휘하는 것으로 내후성 및 가소성을 부여하고, 고온에 노출 시 필름의 유용성을 부여하여 발포가스가 발생 시에 발포가스의 외부 유출을 막아주며, 초기 발포층을 효과적으로 형성할 수 있도록 한다.The colorant exerts durability and plasticity at room temperature, imparts weather resistance and plasticity, imparts usefulness of the film when exposed to high temperature, and prevents the outflow of foaming gas when foaming gas is generated. To form.
이와 같은 전색제는 70중량부 미만으로 혼합 시에는 과다 발포로 인한 탄화층 탈리현상과 밀도 저하로 인한 내화성능을 기대할 수 없으며, 300중량부를 초과하여 혼합하면 탄화층의 밀도가 높은 대신 탄화층 높이가 저하되기 때문에 단열효과를 기대하기 어렵다. 따라서, 본 발명에서 전색제는 정제수 100중량부를 기준으로 70~300 중량부를 혼합하는 것이 바람직하다.When the colorant is less than 70 parts by weight, the carbonization layer desorption due to excessive foaming and the fire resistance due to the lowering of the density cannot be expected. When the mixing agent exceeds 300 parts by weight, the carbide layer has a high density instead of a high density. It is difficult to expect the insulation effect because it is lowered. Therefore, in the present invention, the colorant is preferably 70 to 300 parts by weight based on 100 parts by weight of purified water.
착색안료는 도료의 색상을 부여하기 위하여 혼합하는 것으로 공지의 다양한 착색안료를 사용할 수 있으며, 7중량부 미만으로 혼합 시에는 도료 자체에 색상의 발현이 용이하지 않으며 180중량부를 초과하여 혼합 시에는 색상이 너무 진해지거나 단가가 높아지는 등의 문제가 있기 때문에 정제수 100중량부를 기준으로 착색안료 7~180 중량부를 혼합하는 것이 바람직하다.Colored pigments can be mixed to give the color of the paint can be used a variety of well-known colored pigments, less than 7 parts by weight when mixed with the paint itself is not easy to express the color, when more than 180 parts by weight Since there is a problem such as too thick or the unit price is high, it is preferable to mix 7 to 180 parts by weight of the pigment pigment based on 100 parts by weight of purified water.
암모늄 폴리포스페이트(Ammonium Phosphate)는 촉매제로 사용되며, 고온에서 열분해되어 탄화와 발포에 영향을 미친다. 70중량부 미만으로 혼합 시에는 탄화 및 발포 반응이 적절치 못하며, 300중량부를 초과하여 혼합 시에는 탄화 및 발포 효과를 저해시키기 때문에, 정제수 100중량부를 기준으로 70~300중량부 혼합되는 것이 바람직하다.Ammonium Phosphate is used as a catalyst and is pyrolyzed at high temperatures, affecting carbonization and foaming. When the mixture is less than 70 parts by weight, the carbonization and foaming reaction is not appropriate, and when the mixture exceeds 300 parts by weight, the carbonization and foaming effect is inhibited, so that 70 to 300 parts by weight based on 100 parts by weight of purified water is preferably mixed.
첨가제는 공지의 다양한 증점제, 분산제, 소포제, 가소제 등을 필요에 따라 1종 이상을 혼합하여 사용하도록 할 수 있으며, 15중량부 미만으로 혼합 시에는 기능이 발현되지 않으며 70 중량부를 초과하여 혼합 시에는 경제성이 떨어지기 때문에 정제수 100중량부를 기준으로 15~70중량부를 혼합하는 것이 바람직하다.Additives can be used by mixing one or more kinds of known thickeners, dispersants, antifoaming agents, plasticizers, etc. as necessary, and when mixed to less than 15 parts by weight does not express the function and when mixed in excess of 70 parts by weight It is preferable to mix 15 to 70 parts by weight based on 100 parts by weight of purified water because of poor economy.
보강제로 수산화 알루미늄을 사용하는데, 수산화 알루미늄은 발포도막으로 형성되었을 때 탄화층의 강도를 보강하여 화염이나 바람으로부터 박리 및 날림 현상을 방지하도록 하여 방염성능을 향상시키는 효과가 있다.Aluminum hydroxide is used as a reinforcing agent, and aluminum hydroxide has an effect of improving the flame retardant performance by reinforcing the strength of the carbonized layer when formed into a foamed coating film to prevent peeling and blowing from a flame or wind.
3중량부 미만으로 혼합 시에는 발포층의 강도 부여효과가 나타나지 않으며, 70중량부를 초과하여 혼합 시에는 발포층의 강도가 높아져 갈라짐 현상과 발포율이 현저히 떨어져 방염성능이 떨어지는 문제점이 있다. 따라서 정제수 100중량부를 기준으로 3~70중량부를 혼합하는 것이 바람직하다.When the mixing amount is less than 3 parts by weight, the effect of giving strength of the foam layer does not appear, and when the mixing amount exceeds 70 parts by weight, the strength of the foam layer is increased, the cracking phenomenon and the foaming rate are remarkably decreased, and the flameproofing performance is lowered. Therefore, it is preferable to mix 3 to 70 parts by weight based on 100 parts by weight of purified water.
발포제는 고온에서 열 분해되어 분활성 가스를 방출하여, 방염도료 도막이 탄화된 탄화층을 발포시켜 단열효과를 지속시킬 수 있도록 하는 역할을 한다.The blowing agent thermally decomposes at a high temperature to release the active gas, so that the flame retardant coating film foams the carbonized carbonized layer so that the thermal insulation effect can be maintained.
발포제는 멜라닌을 포함한 질소화합물 등 공지의 다양한 발포제를 사용할 수 있다. 70중량부 미만으로 혼합 시에는 생성되는 가스량이 적어 탄화층 발포가 미흡하고, 150중량부를 초과하여 혼합 시에는 가스의 과량 분출로 균일한 탄화층 형성이 어려우며, 충분한 방염성능을 유지하기 어렵다. 따라서, 정제수 100중량부를 기준으로 70~150중량부를 혼합하는 것이 바람직하다.The blowing agent may use various known blowing agents such as nitrogen compounds including melanin. When the mixing amount is less than 70 parts by weight, the amount of gas generated is insufficient to foam the carbonized layer, and when the mixing amount exceeds 150 parts by weight, it is difficult to form a uniform carbonized layer due to excessive blowing of gas, and it is difficult to maintain sufficient flame retardant performance. Therefore, it is preferable to mix 70-150 parts by weight based on 100 parts by weight of purified water.
특히, 발포조제로 복합 실리케이트 3~70중량부가 추가 혼합되도록 할 수 있다.In particular, 3 to 70 parts by weight of the composite silicate may be added to the foaming aid.
발포조제로 사용되는 복합실리게이트는 분산안정성 유지와 내수성 보강 기능을 부여하며, 고온에서 발포 유지 및 탄화안정성에 기여한다.The composite silicide used as the foaming aid maintains dispersion stability and reinforces water resistance, and contributes to foaming retention and carbonization stability at high temperatures.
따라서, 3중량부 미만으로 혼합 시에는 분산안정성, 내수보강성, 발포유지, 탄화 안정성 등이 떨어지며, 70중량부를 초과하여 혼합 시에는 전색제의 안정성을 떨어뜨려 도료로서의 사용이 불가능하기 때문에, 정제수 100중량부를 기준으로 3~70중량부를 혼합하는 것이 바람직하다.Therefore, when the mixture is less than 3 parts by weight, dispersion stability, water reinforcement, foaming retention, carbonization stability, and the like are inferior, and when it is mixed in excess of 70 parts by weight, the stability of the colorant is not used, and thus it is impossible to use as a paint. It is preferable to mix 3-70 weight part based on weight part.
<실험예 1>Experimental Example 1
정제수 100중량부, 수성 아크릴 에멀젼 수지 150중량부, 첨가제로 소포제와 가소제를 30중량부 및 염화파라핀(염소70%) 10중량부, 복합 실리케이트(Y35 리더씨엔비, 한국) 40중량부, 착색안료(TiO2) 15 중량부, 암모늄 폴리포스페이트 100중량부, 수산화 알루미늄 30중량부 및 발포제 100중량부를 혼합하여 조성물을 제조하였다.100 parts by weight of purified water, 150 parts by weight of aqueous acrylic emulsion resin, 30 parts by weight of antifoaming agent and plasticizer as additives, 10 parts by weight of paraffin chloride (70% chlorine), 40 parts by weight of composite silicate (Y35 ReaderC & B, Korea), pigmented pigment A composition was prepared by mixing 15 parts by weight of (TiO 2 ), 100 parts by weight of ammonium polyphosphate, 30 parts by weight of aluminum hydroxide, and 100 parts by weight of blowing agent.
이후, 대상물에 방청페인트를 도포하고, 방청페인트의 외부에 0.5~0.7mm 두께가 되도록 혼합 조성물을 도포하였으며, 도포횟수는 2회로 제한하였으며, 혼합 조성물의 도포 간격은 1회 도포 후에 12시간 이후에 다시 2회 도포하였다.Thereafter, the anti-rust paint was applied to the object, and the mixed composition was applied to the outside of the anti-rust paint so as to have a thickness of 0.5 to 0.7 mm, and the application frequency was limited to two times, and the application interval of the mixed composition was applied after 12 hours after one application. It was applied twice again.
이후, 실험대상 마우스를 10개체 위치시키고 15분 이상 열을 가하여 연기독성과 발포 개시온도를 측정하였으며, 연기독성에 의한 마우스 10개체 모두 움직임은 영향이 없었으며 발포 개시온도는 125℃ 였다.Subsequently, the test subjects were placed in 10 subjects and heated for 15 minutes or longer to measure smoke toxicity and foaming initiation temperature. The movement of all 10 mice by smoke toxicity had no effect and foaming initiation temperature was 125 ° C.
상기 실험예와 같이, 도포횟수가 적어도 발포가 용이하여 비용절감 및 공기단축효과가 있을 것으로 기대되며, 도막 두께도 0.5~0.7mm에서도 발포가 용이하여 비용이 절감될 뿐만 아니라, 친환경수성제품이기 때문에 화재가 발생하지 않았다.As in the above experimental example, at least the number of coatings is easy to foam, so it is expected to have a cost reduction and air shortening effect, and the film thickness is also easy to foam even at a thickness of 0.5 ~ 0.7mm, because it is an eco-friendly water-based product. There was no fire.
