Description

준불연 단열재 및 이의 제조방법{A semi-inflammable insulation material and manufacturing method for it}A semi-inflammable insulation material and manufacturing method for it}

본 발명은 준불연 단열재 및 이의 제조방법에 관한 것으로, 특히 난연성이 우수하며, 화재발생시 유해가스의 발생을 현저히 줄일 수 있으며, 단열성이 우수하며, 경량으로 단열재의 설치가 용이하며, 방수성이 우수하며, 강도가 우수하며, 동시에 내구성이 우수한 준불연 단열재 및 이를 생산성이 높게 제조할 수 있는 준불연 단열재의 제조방법에 관한 것이다.The present invention relates to a semi-non-combustible insulation material and a method of manufacturing the same, particularly excellent in flame retardancy, can significantly reduce the generation of harmful gases in the event of a fire, has excellent heat insulation properties, and is lightweight, easy to install the insulation material, excellent waterproofness, and , It has excellent strength, and at the same time, it relates to a method of manufacturing a semi-non-combustible insulation material that is excellent in durability and a semi-non-combustible insulation material that can be manufactured with high productivity.

이하에 기술되는 내용은 단순히 본 발명과 관련되는 배경 정보만을 제공할 뿐 종래기술을 구성하는 것이 아니다.The content described below merely provides background information related to the present invention and does not constitute a prior art.

실내 공간은 겨울철 난방이 이루어지고, 에어컨을 이용한 여름철 냉방이 수행되고 있으며, 이러한 실내 공간의 냉난방 효율의 증대는 단열을 통하여 얻을 수 있기 때문에, 다양한 단열재를 이용한 단열 시공이 이루어지고 있다.The indoor space is heated in winter, and cooling is performed in summer using an air conditioner, and since the increase in cooling and heating efficiency of the indoor space can be obtained through heat insulation, heat insulation construction using various insulating materials is being performed.

특히 최근 대형 화재사고로 많은 인명피해와 재산피해가 발생하였는데, 이 화재사고의 경우 건물의 외벽을 난연성능 및 불연성능이 없는 단열재, 접착몰탈, 마감재로 시공을 하는 일명 '드라이비트 공법'으로 시공을 하여 화재 확산 속도가 빨랐고 이로 인해 피해가 더욱 커진 것이 원인으로 지목되고 있다.In particular, a lot of personal and property damage has occurred due to a recent large-scale fire accident.In this case, the outer wall of the building is constructed by the so-called'dry bit method', in which the outer wall of the building is constructed with insulation, adhesive mortar, and finishing materials that do not have flame retardant and non-flammable performance. It was pointed out that the fire spread quickly, and the damage increased further.

이에 정부에서는 '건축물의 피난/방화구조 등의 기준에 관한 규칙'을 개정하여 건축물 마감재료의 화재안전성 기준을 대폭 강화하였으며, 2016년 4월부터 시행되고 있다.Accordingly, the government revised the'Rules on the Standards for Evacuation/Fire Protection of Buildings, etc.' to reinforce the fire safety standards for building finishing materials, which have been implemented since April 2016.

종래 단열 시공에 사용되는 단열재의 대표적인 예로는, 스티로폼, 발포 폴리우레탄, 발포 폴리에틸렌이 주종을 있다. 그 중에서도 폴리우레탄 계열이 가장 우수한 열전도 특성을 갖고 있어 많이 사용된다. 그러나, 단열재로 많이 사용되고 있는 발포 폴리우레탄의 경우, 화재시 인화성이 높고, 화재 초기에 다량의 유독가스가 발생되는 문제로 인해 사용상의 많은 문제점을 갖고 있다.Typical examples of heat insulating materials used in conventional heat insulation construction include styrofoam, foamed polyurethane, and foamed polyethylene. Among them, the polyurethane series is widely used because it has the most excellent heat conduction properties. However, in the case of foamed polyurethane, which is widely used as an insulating material, there are many problems in use due to the high flammability in case of fire and a large amount of toxic gas generated at the beginning of the fire.

종래 우수한 단열재를 제공하기 위하여 페놀 폼 단열재가 개발되기도 하였으나, 페놀 폼 단열재의 경우 강도가 비교적 약하고, 가공이 용이하지 않아 현장에서 단독으로 사용하기에는 한계가 있다.Conventionally, phenolic foam insulation has been developed in order to provide excellent insulation, but in the case of phenolic foam insulation, strength is relatively weak and processing is not easy, so there is a limit to use alone in the field.

또한 대한민국 특허 제1177383호에서는 단열재의 전면에 불연재를 형성하는 단계와, 상기 불연재의 전면과, 상기 단열재의 이면에 알루미늄박지를 형성하는 내화성 복합 소재 제조방법을 개시하였다. 그러나 상기 방법은 내화성 복합소재의 제조가 공정이 지나치게 복잡한 문제가 있으며, 알루미늄 박지가 쉽게 찢어지고 손상되어 단열재의 설치 및 유지에 어려움이 있어 이에 대한 개선이 절실히 요청되고 있다. In addition, Korean Patent No. 11737383 discloses a method of manufacturing a fire-resistant composite material in which a non-combustible material is formed on the front surface of an insulation material, and an aluminum foil is formed on the front surface of the non-combustible material and the rear surface of the insulation material. However, the above method has a problem that the manufacturing process of the fire-resistant composite material is too complex, and the aluminum foil is easily torn and damaged, making it difficult to install and maintain the insulation material, and thus improvement is urgently required.
