Description

방화문과 그 제조방법{Fire door and that of manufacturing method}Fire door and that of manufacturing method

본 발명은 방화문과 그 제조방법에 관한 것으로서, 더욱 상세하게는 불연재인 세라믹 소재로 된 난연종이로 만든 하니컴을 사용함과 동시에 결로방지 및 단열효과를 내는 불연 소재인 알루미늄 반사단열재를 병합 사용하는 것에 관한 것이다.The present invention relates to a fire door and a method of manufacturing the same, and more particularly, to using a honeycomb made of a flame retardant paper made of a non-combustible ceramic material and simultaneously using an aluminum reflective insulating material which is a non-combustible material that exhibits condensation prevention and insulation effects. will be.

일반 종이로 만든 벌집모양의 하니컴(3a)의 양면에 아연도 강판(1)을 일반 접착제(2a)로 부착시켜 만든 종래 방화문의 일부절개 사시도인 도1에서 알 수 있듯이, 종래의 방화문은 일반 판재 상태의 종이로 만든 벌집 모양의 하니컴을 그 양면에 아연도 강판을 일반접착제(2a)로 붙여 방화문으로 사용해 왔다. 그러나 상기 종래의 방화문의 구조는 단열효과를 볼 수 없으며, 결로 발생은 물론 화재시에는 방화문 내부의 하니컴이 모두 연소되면서 인체에 해로운 매연과 열이 그대로 방화문을 통과하여 제2의 화재를 유발시켜 이름대로의 방화문 역할을 못해왔다.As shown in FIG. 1, which is a partially cutaway perspective view of a conventional fire door made by attaching a galvanized steel sheet 1 to the both sides of a honeycomb-like honeycomb 3a made of plain paper, using a general adhesive 2a, the conventional fire door is a plain plate material. Honeycomb-like honeycomb made of paper in a state has been used as a fire door by attaching a galvanized steel sheet to a general adhesive (2a) on both sides thereof. However, the structure of the conventional fire door can not see the heat insulation effect, when condensation occurs and in the event of fire, all the honeycomb inside the fire door is burned, so that the smoke and heat harmful to the human body passes through the fire door, causing a second fire Has not acted as a fire door.

상기 문제점을 해결키위해 몇가지 새로운 고안이 도출되었는 바, 일례로 출원번호 20-2001-0032222(등록번호 20-267122)을 살펴보면, 방화문의 내부 공간부에 보강부재로 종이하니컴을 삽입하여 부착한 경우에는 소음감소효과가 있으나, 화재가 발생할 경우 쉽게 발화되어 방화문의 본래 기능을 저하시키는 폐단 및 외부에 종이하니컴이 부착된 방화문을 설치하여 사용하면 내부와 외부의 온도차로 인한 결로현상이 발생되는 문제점을 해결하기 위해 방화문의 외장판과 내장판에 각각 양면테이프로 보강부재를 부착시키고, 외부를 비닐포장을 한 유리섬유를 방화문의 외장판과 내장판 사이에 삽입함을 구성요소로 하고, 그 결과 방화문의 강도를 증대시키고, 제조시 발생되는 뒤틀림변형을 방지하여 불량률을 저하시키는 것을 목적으로 하고 있다.In order to solve the above problems, several new designs have been derived. For example, application number 20-2001-0032222 (Registration No. 20-267122), for example, shows a case where a paper honeycomb is inserted into a reinforcing member and inserted into an inner space of a fire door. Although it has a noise reduction effect, it is easy to ignite in case of a fire, and the fire doors with paper honeycomb attached to the closed and external doors that deteriorate the original function of the fire doors can cause condensation due to temperature difference between inside and outside. To solve, attach reinforcing members with double-sided tape on the outer and inner panels of fire doors, and insert the glass fiber coated with vinyl between the outer and inner plates of fire doors. The purpose of the present invention is to increase the strength of the resin, to prevent distortion caused during manufacture, and to lower the defective rate.

그러나 상기 고안은 화재발생시 방화문이 쉽게 발화하는 것을 방지하고 결로현상을 막을 수 있지만, 기존의 방화문이 안고 있는 가장 큰 문제인 매연문제는 여전히 해결하지 못하였으며, 또한 출원번호 20-2002-0012335(등록번호: 20-0283673)을 살펴보면 내부단열, 내화 심재로써 페놀 폼, 종이허니컴을 사용하는 복합구조체로서, 표면재로 아연도금강판을 사용하며 10mm의 페놀폼과 중앙 심재로 종이허니컴을 사용하여 제조하는 것을 요지로 하고 있으나, 상기 고안 또한 기존의 방화문 보다는 어느정도 내화성과 효과를 볼 수 있겠으나, 여전히 매연문제는 해결하지 못한 것으로 볼 수 있다.However, the above design prevents fire doors from easily igniting and prevents condensation when fire occurs, but still does not solve the soot problem, which is the biggest problem existing fire doors have, and also has application number 20-2002-0012335 (registration number). : 20-0283673) is a composite structure using phenolic foam and paper honeycomb as internal insulation and refractory core material, using galvanized steel sheet as surface material and paper honeycomb as 10mm phenolic foam and central core material. However, the above invention can also be seen to some extent fire resistance and effect than the existing fire door, but still can not be seen to solve the soot problem.

그리고 2002년 에 개정된 국내 방화문의 조건은 다음과 같다.The conditions of domestic fire door revised in 2002 are as follows.

a. 방화문 한쪽에 800℃를 가열했을때 그 반대쪽이 160℃ 이하로 되도록 단열이 되어야 한다.a. When 800 ℃ is heated on one side of fire door, it should be insulated so that the opposite side is below 160 ℃.

b. 화재시 방화문 내부 소재가 인체에 해로운 매연을 발생시키면 안된다.b. In case of fire, the material inside the fire door should not produce harmful fumes.

c. 결로 발생이 되면 안된다.c. Condensation should not occur.

상기와 같이 방화문의 조건이 까다롭게 됨으로써 국내, 국외에서 사용하고 있는 부피 단열재(스티로폴, 그라스 울 및 우레탄 폼 등...)로서는 상기 방화문으로서의 조건을 만족시키지 못하는 것이 대부분이다. 따라서 그에 맞는 방화문의 도출이 시급한 것이 현실이다.As the conditions of the fire door become difficult as mentioned above, most of the volume insulation materials (Styropole, glass wool, urethane foam, etc.) used domestically and abroad do not satisfy the conditions as the fire door. Therefore, it is urgent to derive fire doors accordingly.

본 발명은 상기 기술한 문제점을 해결하기 위하여, 화재시에 인체에 해로운 매연을 발생시키지 않고 방열 및 결로발생을 방지할 수 있으며, 또한 화재진화 후에도 방화문의 형체가 그대로 유지됨으로서 기존의 부피 단열재로서는 제조가 어려운 방화문과 그 제조방법을 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention can prevent heat radiation and dew condensation without generating harmful fumes in a human body during a fire, and also maintains the shape of a fire door as it is after extinguishing a fire. It is an object of the present invention to provide a fire door and a method of manufacturing the same.

상기 기술한 목적을 달성하기 위하여, 2편의 알루미늄 박막사이에 직접열 또는 간접열(140℃~150℃의 온도로 소성 융착)로 성형강화재가 삽입부착되며 표면에 미세기공이 형성되어 있는 알루미늄 반사단열재와, 상기 알루미늄 반사단열재의 일측에는 세라믹 소재의 하니컴이 일반맥분의 포리졸로 접착되고, 타측에는 난연 폴리에틸렌 폼이 직접열 또는 간접열(140℃~150℃의 온도로 소성 융착)로 부착되며, 각각 세라믹소재의 하니컴과, 난연 폴리에틸렌 폼의 외측에 난연에폭시가 도포되어 아연도강판이 접착되어 있는 방화문과 그 제조방법을 제공한다.In order to achieve the above object, an aluminum reflective insulating material in which a molding reinforcement is inserted and attached by direct heat or indirect heat (plastic fusion welding at a temperature of 140 ° C. to 150 ° C.) between two aluminum thin films, and micropores are formed on a surface thereof. On one side of the aluminum reflective insulating material, a honeycomb of a ceramic material is bonded with a polysol of ordinary powder, and on the other side, a flame-retardant polyethylene foam is attached by direct heat or indirect heat (plastic fusion at a temperature of 140 ° C to 150 ° C), respectively.
