본 발명은 다중 일체형 제조공정을 통해 내화층과 화재확산방지층이 형성된 준불연 우레탄 단열재 및 그 제조방법에 관한 것으로, 더욱 상세하게는 우수한 단열성능을 나타내어 열손실을 저감할 뿐만 아니라, 화재시 난연성 및 내화성을 나타내어 불길의 확산을 차단하고 유독가스의 발생을 억제하는 준불연 우레탄 단열재 및 그 제조방법에 관한 것이다.The present invention relates to a quasi-non-combustible urethane insulator having a fireproof layer and a fire diffusion prevention layer formed through a multi-integral manufacturing process and a manufacturing method thereof, and more particularly, it exhibits excellent thermal insulation performance to reduce heat loss, as well as flame retardancy and It relates to a semi-non-combustible urethane insulation material that exhibits fire resistance to block the spread of flame and suppress the generation of toxic gas, and a method for manufacturing the same.

폴리우레탄 폼으로 이루어진 단열재는 기계적 강도, 치수안정성 및 단열성능 등이 우수하고 시공이 간편하여 샌드위치 패널 사이에 적용되는 형태로 건설현장 등에서 널리 사용되고 있으며, 그 외에도, 냉동이나 냉장창고용 패널 및 LNG, LEG, LPG 등의 탱크 단열용 소재로도 적용되고 있다.Insulation made of polyurethane foam has excellent mechanical strength, dimensional stability and thermal insulation performance, and is easy to construct, so it is widely used in construction sites, etc. It is also applied as a material for insulating tanks such as LEG and LPG.

종래에 폴리우레탄 폼으로 이루어진 단열재는 폴리에테르 폴리올, 폴리에스터 폴리올, 정포제, 촉매 및 발포제 등을 혼합하여 제조된 혼합물에 이소시아네이트계 화합물을 추가로 혼합하고 고압스프레이 기기 등를 통해 발포하는 과정으로 제조되고 있다.Conventionally, insulation made of polyurethane foam is manufactured by adding an isocyanate-based compound to a mixture prepared by mixing polyether polyol, polyester polyol, foam stabilizer, catalyst and foaming agent, and foaming through a high-pressure spray device, etc. have.

그러나, 종래와 같이 폴리우레탄 폼으로 이루어진 단열재의 경우 단열성 뿐만 아니라, 압축강도, 인장강도 및 굴곡강도 등과 같은 기초적인 물성은 우수하지만 화재에 취약하고 발화시 유독가스를 다량 발생시키는 문제점이 있었다.However, in the case of a thermal insulation material made of polyurethane foam as in the prior art, basic physical properties such as compressive strength, tensile strength and flexural strength as well as thermal insulation are excellent, but there is a problem of being vulnerable to fire and generating a large amount of toxic gas when ignited.

상기의 문제점을 해소하기 위해 종래에는 난연성 재료 등을 단열재에 적용하여 난연성능을 부여하고자 하는 시도가 있었으며, 그 예로 인계, 브롬계 및 할로겐계 난연제 등을 첨가하여 일정한 수준으로 화재에 대한 안전성을 확보하였으나 여전히 화재에 취약하고 발화시 유독가스를 다량 발생하는 문제점이 있었다.In order to solve the above problems, there have been attempts to impart flame retardant performance by applying flame retardant materials to insulating materials in the past. For example, phosphorus-based, bromine-based and halogen-based flame retardants, etc. However, it was still vulnerable to fire and generated a large amount of toxic gas when ignited.

최근에는 난연제와 함께 이소시아네이트의 삼량화를 통한 폴리 이소시안유레이트 폼을 형성하여 상기의 문제점에 대해 많은 개선이 있었으나, 상기와 같이 폴리 이소시안유레이트 폼 단독으로는 여전히 난연등급을 충촉하기 어려운 실정이다.Recently, there have been many improvements to the above problems by forming a polyisocyanate foam through trimerization of isocyanate with a flame retardant, but as described above, it is still difficult to meet the flame retardant grade by using the polyisocyanate foam alone. am.

따라서, 이소시안유레이트 폼 위에 난연성을 부여하기 위하여 알루미늄호일이나 유리섬유 등에 팽창흑연을 함유하는 난연성 재료를 이소시안유레이트 폼상하부에 접착하는 연구가 있었으며, 일 예로 대한민국 등록특허 제10-2190353호에는 차열도료층을 가지는 고난연성 단열재가 기재되어 있으나, 상기의 선행기술에는 접착기제로 유기 접착제인 아크릴계 접착제가 사용되어 화재발생시 취약성이 내포되어 있음은 물론 유리섬유 등에 팽창흑연을 함유하는 난연성 재료를 접착하는 공정 접착제를 알미늄호일이나 유리섬유에 도포하는 공정에 사용되는 장비는 제조공정에 중요요소로 코팅 두께를 결정하는 공정인데 종래에는 저 점도는 그라비아 또는 마이크로 그라비아 방식으로, 고점도(1000cps 이상 at room temperate ) 는 콤마방식으로 코팅하였는데. 이는 고가의 장비와 고도의 숙련자가 필요한 공정으로 원가에 매우 큰 비중을 차지하는 부분으로 이다. 이것을 직접 생산하기 위하여 설비를 도입시 우레탄 발포에 비하여 생산속도가 빨라 이 설비는 매우 낮은 가동율을 유지함에따라 높은 가동비용, 높은 감가상각 및 관리인력 등이 결과적으로 외주비용보다 높아질 가능성이 크다 결국 이 부분이 소재의 화재에 대한 안전성이 확보된다하여도 경제성을 이유로 보편적인 보급의 걸림돌로 작용하는 실정이다.Therefore, in order to impart flame retardancy on the isocyanurate foam, there has been a study of adhering a flame retardant material containing expanded graphite to the upper and lower parts of the isocyanurate foam, such as aluminum foil or glass fiber, for example, Republic of Korea Patent No. 10-2190353 Although a high-flammability insulating material having a heat-shielding paint layer is described, in the prior art, an organic adhesive acrylic adhesive is used as an adhesive base, so that it is vulnerable to fire, as well as a flame-retardant material containing expanded graphite on glass fiber. The equipment used in the process of applying the adhesive to aluminum foil or glass fiber is a process that determines the coating thickness as an important factor in the manufacturing process. ) was coated with a comma method. This is a process that requires expensive equipment and highly skilled workers, and is a part that occupies a very large part in the cost. When a facility is introduced to directly produce this, the production speed is faster than that of urethane foam, and as this facility maintains a very low operating rate, high operating costs, high depreciation, and management personnel are likely to be higher than outsourcing costs as a result. Even if the safety of the material is secured against fire, it acts as a stumbling block for universal distribution due to economic reasons.

이에 본 발명의 개발자들은 매우 경제적이며 내화성능이 획기적인 우레탄 단열재를 제공하여 국민의 안전과 열효율을 극대화한 소재로 탄소저감에 기여하고자 본 발명을 개발하게 되었다.Accordingly, the developers of the present invention have developed the present invention to contribute to carbon reduction as a material that maximizes public safety and thermal efficiency by providing a very economical and innovative urethane insulation material with fire resistance performance.
