본 발명은 기능성 불연도료 조성물 및 그 제조방법에 관한 것으로, 더욱 상세하게는 건축물의 실내 벽면이나 내장재 또는 각종 가구류 등에 2단(段)으로 도포되는 경우 제1도포층에서 화열(火熱)을 차단하여 화재를 지연시킴과 동시에 제2도포층에서 산소를 차단하여 화재의 확산을 방지할 수 있도록 함으로써 화염의 전파를 차단할 수 있도록 하는 한편, 피도면(被塗面)에 도포시 들뜸 및 균열현상이 발생 되지 않으며, 내수성이 우수하고 기후변화에 따른 물성의 변화가 없고, 시공성 작업이 용이하며, 색상을 원하는 대로 창출할 수 있도록 한 기능성 불연 도료 조성물 및 그 제조방법에 관한 것이다. The present invention relates to a functional nonflammable coating composition and a method of manufacturing the same, and more particularly, when applied in two stages to an interior wall, interior material, or various furnitures of a building to block heat from the first coating layer. In addition to delaying the fire and blocking oxygen in the second coating layer to prevent the spread of the fire, the propagation of the flame can be blocked. On the other hand, there is no lifting and cracking when applied to the surface to be coated.

일반적으로, 강판은 강도가 우수하고 가공이 용이하여 건축 자재로 많이 사용되고 있다.In general, steel sheet is excellent in strength and easy to process, and is used as a building material.
그러나 강판은 쉽게 부식되는 단점이 있기 때문에 이를 보완하고자 강판 표면에 아연이나 알루미늄 등을 도금하고 크롬산염처리를 하고 있으며, 근본적인 내구력과 미려함을 향상시키기 위하여 기능성의 도료(塗料)를 이용하여 도장(塗裝)을 하는 경우가 많다.However, steel plate has the disadvantage that it is easily corroded, so in order to compensate for this, zinc or aluminum is plated on the surface of the steel plate and chromate treatment is applied. In order to improve the durability and aesthetics, the coating is made by using a functional paint.裝) often do.
하지만, 통상의 도료는 경도가 낮아 표면 손상이 쉽고, 불연성 및 내화성이 없기 때문에 건축물에 화재가 발생하면 기존 건축물의 건축자재와 함께 불에 타버려, 화재를 더욱 가속화시키고 유독가스를 발생시킨다는 문제점이 있다.However, since ordinary paints have low hardness, they are easy to damage the surface, and there is no incombustibility and fire resistance. When a fire occurs in a building, it burns with the building materials of the existing building, further accelerating the fire and generating toxic gas. have.
이에 따라 건축물의 화재부하를 저감(화재 확산방지, 피난, 방화 등)을 위한 기술적 기준을 법령으로 정하여 시험한 결과에 따라 난연 1급에 해당하는 것을 불연, 난연 2급에 해당하는 것을 준불연, 난연 3급에 해당하는 것을 난연이라 등급을 책정하고 있다. As a result of testing the technical standards for reducing the fire load of buildings (prevention of fire, evacuation, arson, etc.) according to the statutes, it is non-combustible, which corresponds to the first class of flame retardant; The flame retardant class is rated as flame retardant.
하지만, 대부분 온전한 불연기능을 하지 못하여 화재시 오히려 무방비 상태라 할 수 있다.However, most of them are incomplete incombustibility and can be said to be defenseless in case of fire.

종래에 사용된 또 다른 난연 도료는 대한민국 등록특허 제 555443호에서 보는 바와 같이 폐스티로폼을 방향족 유기용매인 크실렌 또는 톨루엔에 용해시키고 완전히 용해된 용액에 염화고무와 염화파라핀을 용해시킨 다음 변성용 오일을 첨가하고 교반하여 제조된 투명한 도료를 예로 들 수 있다.Another flame retardant paint used in the prior art is dissolving waste styrofoam in xylene or toluene, an aromatic organic solvent and dissolving rubber chloride and paraffin chloride in a completely dissolved solution, as shown in the Republic of Korea Patent No. 555443. An example is a transparent paint prepared by addition and stirring.

After adding 30% by weight of aluminum hydroxide, 5% by weight of sodium metasilicate, 5% by weight of catalyst, and 15% by weight of titanium oxide, the mixture was stirred at 1,500 to 2,500 rpm for 25 to 35 minutes to prepare a functional non-combustible coating composition according to the present invention. The oxygen blocking agent which comprises is obtained.
이와 같이 제조된 기능성 불연도료 조성물중 화열차단제를 건축재의 피도면에 1.0mm의 두께로 도포하고, 상기 화열차단제의 표면에 상기 산소차단제를 0.5mm의 두께로 도포하면, 화재발생시 1,000℃ 이상의 고온에서도 불이 잘 붙지 않는 것은 물론, 상기 화열차단제의 화열차단 작용 및 산소차단제의 산소차단 작용에 의하여 화재의 확산이 방지되는 것이다.If the thermal barrier agent in the functional non-combustible coating composition prepared as described above is applied to the surface of the building material to have a thickness of 1.0 mm, and the oxygen barrier agent is applied to the surface of the thermal barrier agent at a thickness of 0.5 mm, the fire is prevented even at a high temperature of 1,000 ° C. or higher. Of course, the spread of the fire is prevented by the heat blocking action of the heat blocking agent and the oxygen blocking action of the oxygen blocking agent.
상기 화열차단제와 산소차단제가 피도면에 대하여 이음매 없이 1.5mm의 두께로 도포되는 경우 도막(塗膜)상태로 형성되어 열 분리 현상이 발생되지 않으며, 들뜸 및 균열이 발생되지 않고, 내수성이 크게 향상된다.When the thermal barrier agent and the oxygen barrier agent are applied with a thickness of 1.5 mm without a seam on the surface to be coated, they are formed in a coating state, and thermal separation does not occur, and there is no lifting and cracking, and water resistance is greatly improved. .
