Abstract

Fireproof insulation materials are integrally molded by spraying non-combustible inorganic materials when full water is foamed, so that a sealing body is seamlessly connected in the fireproof insulation materials to effectively block heat conduction, thereby enhancing energy saving effects while enhancing fire protection and insulation effects. In particular, since only water is foamed through full-water foaming, it is not necessary to use a foaming agent when foaming, so that odors caused by the use of a foaming agent can be prevented. Since the fireproof insulation materials are molded in a full-water foaming method, CO_2 generated by a reaction between water and isocyanate swells and remains in the grooves formed in the foam, thereby improving thermal conductivity to obtain a superior insulation effect compared to existing expanded polystyrene (EPS), extruded polystyrene (XPS), and polyurethane.

It is relatively high and easily diffuses heat, so it can increase the thermal insulation performance.

(3) 이에, 기존의 다른 보온재인 EPS(Expanded PolyStyrene), XPS( Extruded PolyStyrene), 그리고 폴리우레탄보다 우수한 보온 효과를 얻을 수 있다.(3) Accordingly, it is possible to obtain a better thermal insulation effect than other existing insulation materials such as EPS (Expanded PolyStyrene), XPS (Extruded PolyStyrene), and polyurethane.

(4) 또한, 이처럼 보온 효과가 우수하므로, 전수 발포 방식과 불연 무기재료의 혼합 비율을 조절하여 원하는 보온 효과를 얻을 수 있는 두께로 방화 보온 재료를 제작할 수 있다.(4) In addition, since the thermal insulation effect is excellent, a fireproof thermal insulation material can be manufactured with a thickness capable of obtaining a desired thermal insulation effect by adjusting the mixing ratio of the water-cold foaming method and the non-combustible inorganic material.

(5) 그리고 이처럼 전수 발포 방식으로 물이외의 다른 발포제를 사용하지 않고 발포 성형하므로, 다른 발포제 사용으로 인한 악취 발생을 사전에 방지할 수 있다. 이에, 작업자는 쾌적한 작업환경에서 작업할 수 있을 뿐만 아니라 이용자는 안전하게 사용할 수 있다.(5) And since it is foam-molded without the use of other foaming agents other than water in this full-water foaming method, it is possible to prevent the occurrence of odors caused by the use of other foaming agents. Accordingly, not only the worker can work in a comfortable working environment, but the user can use it safely.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 더욱 상세히 설명하기로 한다. 이에 앞서, 본 명세서 및 청구범위에 사용된 용어나 단어는 통상적이거나 사전적인 의미로 한정해서 해석되어서는 안 되며, 발명자는 그 자신의 발명을 최고의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 따라 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as being limited to their usual or dictionary meanings, and the inventor should appropriately define the concept of terms in order to describe his own invention in the best way. It should be interpreted as a meaning and concept consistent with the technical idea of the present invention according to the principle that it can be.

따라서 본 명세서에 기재된 실시예와 도면에 도시된 구성은 본 발명의 가장 바람직한 일 실시예에 불과할 뿐이고 본 발명의 기술적 사상을 모두 대변하는 것은 아니므로, 본 출원 시점에서 이들을 대체할 수 있는 다양한 균등물과 변형례가 있을 수 있음을 이해하여야 한다.Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiment of the present invention and do not represent all the technical spirit of the present invention, and various equivalents that can replace them at the time of the present application And it should be understood that there may be variations.

본 발명의 [실시예 1]에 따른 방화 보온 재료의 발포 성형방법은, 멜라민 수지(A)와 이소시아네이트(B)를 혼합하고, 동시에 불연 무기재료(C)를 함께 분사하여 전수(全水) 발포 방식으로 성형하되, 상기 멜라민 수지(A)와 이소시아네이트(B)의 질량비(A:B)를 1: 1~1.2로 혼합한 것이다.In the foam molding method of the fireproof insulating material according to [Example 1] of the present invention, a melamine resin (A) and an isocyanate (B) are mixed, and at the same time, a non-combustible inorganic material (C) is sprayed together to form full water. However, the mass ratio (A:B) of the melamine resin (A) and the isocyanate (B) is mixed in a ratio of 1: 1 to 1.2.

이에, 상기 불연 무기재료(C)가 전수 발포 성형한 방화 보온 재료 안에서 끊김 없이 밀봉체를 형성함으로써, 열전도를 효과적으로 차단함에 따라 에너지 효율을 높이고 이에 보온 효과를 높일 수 있게 한 것이다.Accordingly, the non-combustible inorganic material (C) forms a sealing body seamlessly in the fireproof thermal insulation material formed by water-foaming, thereby effectively blocking heat conduction, thereby increasing energy efficiency and thus increasing the thermal insulation effect.

또한, 전수(全水) 발포 방식으로 방화 보온 재료를 발포 성형함으로, 물과 많은 이소시아네이트가 반응하여 생기 CO2가 방화 보온재료 안에 잔류하게 되고, CO2의 비교적 높은 열전도도를 이용하여 쉽게 확산 작용이 이루어지게 하여 보온성능을 높일 수 있게 한 것이다. 그리고 전수 발포로 다른 발포제를 사용하지 않고 물로 발포 성형하므로, 발포제 사용으로 인한 악취가 생기지 않아 쾌적한 작업 환경에서 작업할 수 있을 뿐만 아니라 안전하게 사용할 수 있게 한 것이다.In addition, by foaming the fireproof insulation material in a full water foaming method, CO 2 generated by the reaction of water and many isocyanates remains in the fire protection insulation material, and it diffuses easily using the relatively high thermal conductivity of CO 2 This is done so that the thermal insulation performance can be improved. In addition, since it is foam-molded with water without using other foaming agents, it is possible to work in a comfortable working environment as well as safely use because there is no odor caused by the use of the foaming agent.

이하, 이러한 구성에 관해 상세하게 설명하면 다음과 같다. 여기서는, 발포 성형에 사용하는 재질을 먼저 설명하고, 전수 발포 성형에 관해서는 후술한다.Hereinafter, this configuration will be described in detail. Here, the material used for foam molding will be first described, and the total water foam molding will be described later.

가. 멜라민 수지end. Melamine resin

멜라민 수지(A)는 멜라민과 폼아데하이드 사이에 축합반응으로 생성하는 열경화성 재질로, 단단하고 열에 강하고 내마찰력과 열안정성 그리고 내화학성이 우수한 것으로 알려졌다.Melamine resin (A) is a thermosetting material that is generated by a condensation reaction between melamine and formaldehyde, and is known to be hard, heat-resistant, and excellent in friction resistance, thermal stability, and chemical resistance.

특히, 본 발명에 따른 멜라민 수지(A)는, 다음과 같은 (1) 히드록시메틸화 반응과 (2) 에테르화 반응을 거쳐서 얻은 헥사메틸멜라민 수지를 사용한다.In particular, the melamine resin (A) according to the present invention uses a hexamethylmelamine resin obtained through the following (1) hydroxymethylation reaction and (2) etherification reaction.

1. 히드록시메틸화 반응1. Hydroxymethylation reaction

히드록시메틸화 반응은, 멜라민, 파라포름알데히드, 메탄올을 반응용기에 투입한 다음, 무기염기를 사용하여 pH 지수 7.5~9.5로 조절하고, 온도 60℃~70℃로 2~3시간 유지하여 헥사메틸멜라민이 결정화가 될 때까지 반응한다. 이때, 헥사메틸멜라민이 결정화가 이루어질 때까지는 보온을 유지한 다음 다시 온도를 낮춘다.In the hydroxymethylation reaction, melamine, paraformaldehyde, and methanol are added to the reaction vessel, and then the pH index is adjusted to 7.5 to 9.5 using an inorganic base, and the temperature is maintained at 60 to 70° C. for 2 to 3 hours. It reacts until the melamine crystallizes. At this time, the heat retention is maintained until the hexamethylmelamine crystallizes, and then the temperature is lowered again.

이때, 상기 멜라민 수지와 파라포름알데히드 그리고 메탄올의 반응 분자비는 1:(8~9):(15~20)으로 혼합하여 사용하는 것이 바람직하다.At this time, the reaction molecular ratio of the melamine resin, paraformaldehyde, and methanol is preferably used by mixing 1: (8 ~ 9): (15 ~ 20).

2. 2. 에테르화Etherification 반응 reaction

에테르화 반응은, 상술한 히트록시메탈 반응으로 얻은 헥사메틸멜라민에 에탄올과 유기산을 넣어 pH 지수를 3~6으로 조절하여 에테르화 반응을 진행한다. 이때, 온도는 60℃~70℃로 10~20시간으로 반응한 다음, 다시 무기염기를 넣어 중성으로 조절한 뒤에 진공에서 메탄올과 수분을 제거하여 헥사메틸멜라민 수지를 얻는다.In the etherification reaction, ethanol and an organic acid are added to hexamethylmelamine obtained by the above-described heat oxymetal reaction, and the pH index is adjusted to 3 to 6 to proceed with the etherification reaction. At this time, the temperature is reacted at 60°C to 70°C for 10 to 20 hours, and then the inorganic base is added to neutralize it, and methanol and moisture are removed in a vacuum to obtain a hexamethyl melamine resin.

이때, 상기 무기염기로는 수산화나트륨을 사용하고, 상기 유기산으로는 포름산을 사용하는 것이 가장 바람직하다.In this case, sodium hydroxide is most preferably used as the inorganic base, and formic acid is most preferably used as the organic acid.

이처럼, 상술한 (1) 히드록시메틸화 반응과 (2) 에테르화 반응을 거쳐서 얻은 헥사메틸멜라민 수지의 물성은 다음과 같다.As described above, the physical properties of the hexamethylmelamine resin obtained through the above-described (1) hydroxymethylation reaction and (2) etherification reaction are as follows.

나. 이소시아네이트I. Isocyanate

이소시아네이트(B)는, 폴리우레탄을 제조할 때 폴리올과 함께 주원료로 사용하는 것으로 잘 알려졌다. 특히, 본 발명에서, 상기 이소시아네이트(B)로는 헥사메틸에틸렌글리콜을 사용하고, 상술한 멜라민 수지(A)와 이소시아네이트(B)의 질량비(A:B)는 1:(1~1.2)로 혼합하여 사용한다.Isocyanate (B) is well known to be used as a main raw material together with polyols when producing polyurethane. In particular, in the present invention, hexamethylethylene glycol is used as the isocyanate (B), and the mass ratio (A:B) of the melamine resin (A) and isocyanate (B) is 1: (1 to 1.2) use.

다. 불연 무기재료All. Incombustible inorganic material

불연 무기재료(C)는 상술한 멜라민 수지(A)와 이소시아네이트(B)를 혼합하여 전수 발포할 때 함께 혼합함에 따라 방화 보온 재료 안에서 넓게 분산하여 끊김 없이 밀봉체가 연결되게 하여 열 전도를 효과적으로 차단하여 에너지 절약 효과를 높이면서도 방화와 보온 효과를 높일 수 있게 한다. 이러한 불연 무기재료(C)로는 무기광물 섬유, 유리섬유 및 글라스 울 중에서 적어도 하나로 이루어진 것을 사용한다.The non-combustible inorganic material (C) is mixed with the above-described melamine resin (A) and isocyanate (B) and dispersed widely in the fire-retardant insulation material as they are mixed together when the above-described melamine resin (A) and isocyanate (B) are mixed together, so that the sealant is seamlessly connected to effectively block heat conduction. While increasing the energy saving effect, it is possible to increase the fire prevention and thermal insulation effect. As the nonflammable inorganic material (C), at least one of inorganic mineral fibers, glass fibers and glass wool is used.

라. 전수 발포la. Full foam

전수 발포는, 상술한 멜라민 수지(A)와 이소시아네이트(B) 그리고 불연 무기재료(C)의 조성비는 1:(1~1.2): (0.5~1.5)인 준비하고, 상기 멜라민 수지(A)와 이소시아네이트(B)를 혼합할 때, 상기 불연 무기재료(C)를 함께 분사하여 방화 보온 재료를 형성하는 발포 방식이다.Total water foaming was prepared in which the composition ratio of the above-described melamine resin (A), isocyanate (B), and non-combustible inorganic material (C) was 1: (1 to 1.2): (0.5 to 1.5), and the melamine resin (A) and When mixing the isocyanate (B), it is a foaming method in which the above non-combustible inorganic material (C) is sprayed together to form a fire protection insulating material.

이러한 전수 발포 방식은 물을 기반으로 사용하므로, 발포 과정에서 물과 이소시아네이트가 반응하여 CO2를 생성하게 되고, 생성된 CO2가 발포한 홈 안에 잔류하여 방화 보온 재료가 발포 생성된다. 이때, CO2는 열전도도가 비교적 높아 열이 잘 확산하므로 보온 성능을 높일 수 있다. 이때 전수 발포 방식의 열전도도가 대략 0.024-0.028w/m·k 정도로, 보온재로 사용하는 기존 EPS(Expanded PolyStyrene), XPS( Extruded PolyStyrene), 그리고 폴리우레탄보다는 우수한 보온 효과를 얻는다.Since this water-based foaming method is based on water, water and isocyanate react during the foaming process to generate CO 2 , and the generated CO 2 remains in the foamed grooves, thereby foaming the fireproof insulating material. At this time, the thermal conductivity of CO 2 is relatively high, so heat spreads well, so the thermal insulation performance can be improved. At this time, the thermal conductivity of the full water foaming method is about 0.024-0.028w/m·k, and it obtains a better thermal insulation effect than the existing EPS (Expanded PolyStyrene), XPS (Extruded PolyStyrene), and polyurethane used as insulation materials.

특히, 이러한 전수발포 방식은 발포 성형할 때 발포제를 사용하지 않고 물로 발포 성형한다. 이에, 멜라민 수지(A)를 발포 성형할 때 발포제를 사용하지 않으므로, 발포제 사용으로 인한 악취가 생기지 않아 쾌적한 작업 환경에서 작업할 수 있을 뿐만 아니라 이용자도 안전하게 사용할 수 있다.Particularly, in this full-water foaming method, foam molding is performed with water without using a foaming agent. Accordingly, since a foaming agent is not used when the melamine resin (A) is foamed, there is no odor caused by the use of the foaming agent, so that not only can work in a comfortable working environment, but also users can safely use it.

한편, 이러한 전수 발포는, 아래의 [표 2]와 같은 조건에서 전수 발포가 이루어지게 한다.On the other hand, such water-repellent foaming allows water-tight foaming to occur under conditions as shown in [Table 2] below.

여기서, CT(Cream Time)은 멜라민 수지(A)와 이소시아네이트(B)를 혼합하기 시작할 때부터 반응 혼합액이 크림(Cream) 상태로 변화가 일어났을 때까지의 시간(Sec)을, GT(Gel Time)는 멜라민 수지(A)와 이소시아네이트(B)를 혼합한 뒤에 점도가 상승하여 굳어지는데 걸리는 시간을, TFT(Track free Time)은 멜라민 수지(A)와 이소시아네이트(B)의 반응 혼합물로 얻은 폼 표면의 접착성이 없어지는 시간을 각각 나타낸다. Here, CT (Cream Time) is the time (Sec) from the start of mixing the melamine resin (A) and the isocyanate (B) until the reaction mixture changes to a cream state (Sec), and GT (Gel Time) ) Is the time it takes for the viscosity to increase and harden after mixing the melamine resin (A) and isocyanate (B), and the TFT (Track Free Time) is the foam surface obtained from the reaction mixture of melamine resin (A) and isocyanate (B). The time at which the adhesiveness disappears is shown, respectively.

한편, 이처럼 전수 발포 방식으로 얻은 방화 보온 재료는, 다음이 [표 3]과 같은 제품 성능을 갖는다.On the other hand, the fireproof heat insulating material obtained by the water-cold foaming method has the following product performance as shown in [Table 3].

이상과 같이 전수 발포하면서 불연 무기재료를 함께 분사하면서 전수(全水) 발포 방식으로 제작한 방화 보온 재료는 악취가 많이 나지 않으면서도 열전도도가 우수하여 에너지 절약 효과를 높일 수 있을 뿐만 아니라 흡음 효과도 뛰어나며 내부에 불연 무기재료가 포함되어 방화 등급을 올릴 수 있게 된다. As described above, the fireproof insulating material produced by the all-water foaming method while spraying non-combustible inorganic materials together with water-absorbing foaming does not produce much odor and has excellent thermal conductivity, thereby enhancing energy saving effect as well as sound-absorbing effect. It is excellent and contains non-combustible inorganic materials inside, which makes it possible to raise fire protection ratings.

Accordingly, a detailed description of the same configuration as in [Example 1] is omitted here, and a description will be made focusing on a method of mixing and injecting a non-combustible inorganic material (C) as a different configuration.
