According to the present invention, a sealing member is inserted into a door frame to maintain airtightness of a fire door and comprises a thermoplastic polymer substance, a forming agent coming in contact with the fire door when heated, an elastic body, graphite heated to increase the volume, a flame retardant, and thermoplastic synthetic oil. According to the present invention, the sealing member comprises the thermoplastic polymer substance, the forming agent, the elastic body, the graphite, the flame retardant, and the synthetic oil to prevent the sealing member from being combusted to scatter in an ash form when a fire occurs, and thermally expands and solidifies between the door frame and the fire door to maintain airtightness. The sealing member is easily shape-changed and installed by a user when installing the sealing member on the door frame and forms a contact surface with the door frame by using restoring force after being installed on the door frame. Therefore, the sealing member can be prevented from escaping out of the door frame.
본 발명은 문틀에 삽입되어 방화문의 기밀을 유지하는 실링부재로서, 열가소성의 고분자물, 가열 시 방화문과 접하는 성형제, 탄성체, 가열되어 부피가 증가하는 흑연, 난연제 및 열가소성 합성오일을 포함한다. 본 발명에 따르면, 고분자물, 성형제, 탄성체, 흑연, 난연제 및 합성오일을 포함하는 실링부재가 구비됨으로써, 화재 발생 시 실링부재가 연소되어 재 형태로 비산하는 것을 방지하고, 문틀 및 방화문의 사이에서 열 팽창 및 응고됨으로써 기밀을 유지할 수 있으며, 실링부재는 문틀에 설치 시 사용자에 의해 용이하게 형태 변형 및 설치되고 문틀에 설치된 이후 복원력을 이용하여 문틀과 면접촉을 이루기 때문에, 문틀의 외부로 이탈되지 않을 수 있다.
