Description
본 발명은 난연보드 및 그의 제조방법에 관한 것으로, 보다 상세하게는 에멀젼 상태의 멜라민 수용성 수지 제조 단계, 상기 에멀젼 상태의 멜라민 수용성 수지에 화이바 글라스를 함침시키는 단계, 건조 단계, 성형 단계, 냉각 단계 및 글래스 코팅 단계를 포함하는 난연보드의 제조방법 및 상기의 방법에 의해 제조된 난연보드에 관한 것이다.The present invention relates to a flame retardant board and a method for manufacturing the same, and more specifically, to a step of producing a melamine water-soluble resin in an emulsion state, a step of impregnating fiber glass into the melamine water-soluble resin in an emulsion state, a drying step, a molding step, a cooling step, and It relates to a method of manufacturing a flame retardant board including a glass coating step and a flame retardant board manufactured by the above method.
난연성 보드는 불연(난연 1급), 준불연(난연 2급), 난연(난연 3급)으로 나누어지는데, 난연성 보드는 통상 발포 입자에 난연제를 코팅하고, 코팅된 난연비드를 성형하는 방식으로 제조되고 있다.Flame retardant boards are divided into non-retardant (flame retardant grade 1), semi-incombustible (flame retardant grade 2), and flame retardant (flame retardant grade 3). Flame retardant boards are usually manufactured by coating foam particles with a flame retardant and molding the coated flame retardant beads. It is becoming.
상기 불연 등급인 난연 1등급 단열재의 종류로는 그라스울, 미네랄울 등이 있고, 준불연 등급인 난연 2등급 단열재의 종류로는 준불연 EPS, 준불연 비드법 단열재, PF보드, 준불연 경질 우레탄보드, 준불연 열반사 단열재 등이 있으며, 상기 난연 등급(실제론 가연 제품)인 난연 3등급에는 압출법 보온판, 일반 경질 우레탄보드, 일반 열반사 단열재, 일반 비드법 단열재 등이 있다.Types of flame retardant grade 1 insulation materials that are non-combustible include glass wool and mineral wool, and types of flame retardant grade 2 insulation materials that are semi-non-combustible include semi-non-combustible EPS, semi-non-combustible bead method insulation, PF board, and semi-non-combustible hard urethane board. , semi-non-combustible heat-reflecting insulation materials, etc., and flame retardant grade 3, which is the above-mentioned flame retardant grade (actually combustible product), includes extruded insulation boards, general rigid urethane boards, general heat-reflecting insulation materials, and general bead-based insulation materials.
난연성 보드의 난연성은 난연제의 양에 의해서 결정되는데, 난연성을 높이기 위하여 난연제를 다량으로 사용하는 경우 난연 입자들 간의 융착력이 약해져서 부스러지는 문제점과, 열전도성이 높아져서 단열성이 저하되는 문제점이 발생한다. 이로 인해 난연성 보드로 샌드위치 패널을 제조하는 경우 금속판과 난연성 보드가 서로 박리되 는 경우가 발생하기도 한다.The flame retardancy of a flame retardant board is determined by the amount of flame retardant. If a large amount of flame retardant is used to increase flame retardancy, the adhesion between flame retardant particles becomes weak and the board crumbles, and the thermal conductivity increases, causing a decrease in insulation properties. Because of this, when manufacturing a sandwich panel with a flame retardant board, there are cases where the metal plate and the flame retardant board are separated from each other.
난연보드에 관한 종래기술로는 건축용 불연 보드 및 그 제조방법(대한민국 등록특허공보 제10-1551542호), 난연성 보드의 제조방법(대한민국 등록특허공보 제10-2024348호), 난연 단열보드(대한민국 공개특허공보 제10-2022-0012469호) 등이 알려져 있다. Conventional technologies related to flame retardant boards include fire-retardant boards for construction and their manufacturing method (Korea Patent Publication No. 10-1551542), flame-retardant board manufacturing methods (Korea Patent Publication No. 10-2024348), and flame-retardant insulation boards (Korea Publication). Patent Publication No. 10-2022-0012469) etc. are known.
그러나, 상기 종래기술들을 포함하여 실제 시중에 판매되는 많은 난연성 보드들의 실제 제품은 규격시험을 통과하지 못하는 것이 많아, 실질적으로 인명과 재산을 보호할 수 있는 난연성 보드와 관련된 기술개발이 요청되고 있는 실정이다.However, many of the actual products of flame retardant boards sold on the market, including the above prior technologies, do not pass the standard test, so there is a demand for technology development related to flame retardant boards that can actually protect life and property. am.

본 발명의 상기 난연본드는 건축용 내장재로서의 사용을 목적으로 제조되는 것으로서, 이러한 건축용 내장재의 난연성 성능 평가의 기준인 '건축물 마감재료의 난연성능 및 화재 확산 방지구조 기준'(국토해양부 고시 제2012-624호)에 의한 성능 시험에 의할 때 난연 2급 이상을 만족한다.The flame retardant bond of the present invention is manufactured for the purpose of use as an interior material for construction, and is the standard for evaluating the flame retardancy performance of such interior materials for construction, 'Standards for flame retardant performance and fire spread prevention structures of building finishing materials' (Ministry of Land, Transport and Maritime Affairs Notification No. 2012-624) According to the performance test according to (#), it satisfies flame retardancy grade 2 or higher.
'건축물 마감재료의 난연성능 및 화재 확산 방지구조 기준'(국토해양부 고시 제2012-624호)는 그 난연 등급을 난연 1급(난연재료), 난연 2급(준불연재료), 난연 3급(불연재료)로 구분하는데, 이러한 난연성능 기준에 있어 가장 중요한 문제는 다음과 같이 요약된다.'Standards for flame retardant performance and fire spread prevention structures of building finishing materials' (Ministry of Land, Transport and Maritime Affairs Notice No. 2012-624) categorizes the flame retardancy grades into flame retardant grade 1 (flame retardant materials), flame retardant grade 2 (semi-non-combustible materials), and flame retardant grade 3 ( The most important issues in these flame retardant performance standards are summarized as follows.
먼저, 연소시 연소가스의 발생이 적어야 한다. 이는 연소시 발생하는 가스가 인화하여 총열방출률을 높이거나, 로 내에서 온도를 상승하는 작용을 할 수 있기 때문이며, 또한 가스 유해성 시험에서 마우스의 행동정지시간을 단축하는 악영향이 있기 때문이다.First, the generation of combustion gases during combustion must be small. This is because the gas generated during combustion can ignite and increase the total heat release rate or increase the temperature within the furnace, and also has the negative effect of shortening the mouse's behavioral suspension time in the gas hazard test.
둘째, 발생가스에 독성이 적어야 한다. 이는 연소시 발생하는 독성 가스가 마우스의 행동정지시간을 단축하는 가장 중요한 요소이기 때문이다.Second, the generated gas must be less toxic. This is because the toxic gases generated during combustion are the most important factor in shortening the mouse's behavioral suspension time.
마지막으로 연소시 증발량이 적어야 한다. 이는 난연재료 성능 시험시 질량 감소율을 증대할 수 있기 때문이다. Lastly, the amount of evaporation during combustion must be low. This is because the mass reduction rate can be increased when testing flame retardant material performance.
