Abstract
Description
본 발명은 연소가스 유독성이 저감된 폴리이소시아누레이트를 포함하는 단열재에 관한 것이다.The present invention relates to a heat insulating material containing polyisocyanurate with reduced flue gas toxicity.
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 the 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. Since the increase in cooling and heating efficiency of this indoor space can be obtained through insulation, insulation construction using various heat insulating materials is being performed.
특히 최근 대형 화재사고로 많은 인명피해와 재산피해가 발생하였는데, 이 화재사고의 경우 건물의 외벽을 난연 성능 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 large-scale fire accident recently caused a lot of casualties and property damage. In this case of fire, the exterior walls of the building were constructed using the so-called 'dry bit method', in which the building's exterior walls were constructed with insulation, adhesive mortar, and finishing materials without flame-retardant or non-combustible performance. This is attributed to the rapid spread of the fire, which in turn caused more damage.
이에 정부에서는 '건축물의 피난/방화구조 등의 기준에 관한 규칙'을 개정하여 건축물 마감재료의 화재안전성 기준을 대폭 강화하였으며, 2016년 4월부터 시행되고 있다.Accordingly, the government has significantly strengthened the fire safety standards for building finishing materials by amending the 'Rules on Standards for Evacuation/Fire Protection Structures of Buildings', and has been in effect 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, 화재 시 인화성이 높고, 화재 초기에 다량의 유독가스가 발생되는 문제로 인해 사용상의 많은 문제점을 갖고 있다.Representative examples of thermal insulation materials used in conventional insulation construction include styrofoam, polyurethane foam, and polyethylene foam. Among them, polyurethane is widely used because it has the best thermal conductivity. However, polyurethane foam, which is widely used as an insulator, has many problems in use due to its high flammability in case of fire and the generation of a large amount of toxic gas in the early stage of a 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, phenol foam insulation has been developed to provide an excellent insulation material, but in the case of phenol foam insulation material, the strength is relatively weak and processing is not easy, so there is a limit to use alone in the field.
본 발명은 난연성이 우수하며, 방수성이 우수하며, 화재발생시 유해가스의 발생을 현저히 줄일 수 있으며, 단열성이 우수하며, 경량으로 단열재의 설치가 용이하며, 강도가 우수하며, 외관이 수려하며, 동시에 내구성이 우수한 폴리이소시아누레이트를 포함하는 단열재 및 이를 생산성이 높게 제조하는 것이 가능한 폴리이소시아누레이트를 포함하는 단열재를 제공하는 것을 목적으로 한다.The present invention has excellent flame retardancy, excellent waterproofness, can significantly reduce the generation of harmful gases in case of fire, has excellent thermal insulation properties, is lightweight and easy to install, has excellent strength, has a beautiful appearance, and at the same time An object of the present invention is to provide an insulating material containing polyisocyanurate having excellent durability, and an insulating material containing polyisocyanurate capable of producing the same with high productivity.
