Description
본 발명은 섬유로서 마(麻) 섬유를 포함하는 압출성형 패널과, 이러한 압출성형 패널의 표면에 도포되는 무기계 내화도료 조성물, 그리고 이를 이용하여 압출성형 패널의 내화성능을 향상시키는 방법에 관한 것이다. The present invention relates to an extrusion-molded panel containing hemp fiber as a fiber, an inorganic fire-resistant paint composition applied to the surface of such an extrusion-molded panel, and a method of improving the fire-resistant performance of the extrusion-molded panel using the same.
구체적으로 본 발명은 무기 바인더(구체적으로는 액상 규산나트륨)을 용매로 사용하고, 무기계(non-organic) 분말로서 밀드 카본, 마이카 및 알루미나 분말을 포함하는 조성을 가지고 있으며, 압출성형 패널의 표면에 도포됨으로써 압출성형 패널의 내화(耐火)성능을 향상시키는 "무기계 내화도료 조성물"에 관한 것이다. Specifically, the present invention uses an inorganic binder (specifically, liquid sodium silicate) as a solvent, has a composition containing milled carbon, mica, and alumina powder as an inorganic (non-organic) powder, and is applied to the surface of an extrusion molded panel. It relates to an “inorganic fire-resistant paint composition” that improves the fire resistance performance of extrusion molded panels.
또한 본 발명은 상기한 무기계 내화도료 조성물에 의해 표면이 도포되어 있으며, 더 나아가 내열성이 우수한 마(麻) 섬유를 포함하도록 성형 제작됨으로써 우수한 내화성능 및 보강성능을 발휘하게 되는 압출성형 패널에 관한 것이다, In addition, the present invention relates to an extrusion-molded panel whose surface is coated with the above-described inorganic fire-resistant paint composition, and which is further molded to include hemp fibers with excellent heat resistance, thereby exhibiting excellent fire resistance and reinforcement performance. ,
또한 본 발명은 압출성형 패널에 상기한 무기계 내화도료 조성물을 도포함으로써 압출성형 패널의 내화성능을 향상시키는 방법에 관한 것이다. The present invention also relates to a method of improving the fire resistance performance of an extrusion-molded panel by applying the above-described inorganic fire-resistant paint composition to the extrusion-molded panel.
각종 제품의 내화성능 개선을 위한 방법으로서 내화(耐火)도료를 사용하는 것이 일반적이다. 통상 내화도료는 온도가 상승함에 따라 표면에 다공성의 기포를 생성하게 되고, 이를 통해서 열을 차단하는 기능을 발휘하게 된다. 철골내화 피복재로서 많이 사용하는 종래의 도료형 내화 페인트는 최대 2시간까지 내화성능 시간을 연장시키는 작용을 한다. 여기서 "내화성능 시간"은 화재를 견디거나 방호할 수 있는 시간으로서, 구체적으로는 압출성형 패널에 열이 가해졌을 때, 패널에서 열이 직접적으로 가해진 면의 반대쪽 면 즉, 패널의 이면에서의 온도가 평균 섭씨 140도, 그리고 최대온도가 섭씨 180도에 도달하는 시점이 내화성능 시간이 된다.It is common to use fire-resistant paint as a way to improve the fire resistance of various products. Typically, as the temperature of fireproof paint increases, porous bubbles are created on the surface, and through this, it exerts the function of blocking heat. Conventional paint-type fireproof paint, which is widely used as a fireproof covering material for steel structures, has the effect of extending the fireproof performance time by up to 2 hours. Here, “fire resistance time” refers to the time that can withstand or protect against fire. Specifically, when heat is applied to an extrusion molded panel, the temperature on the side of the panel opposite to the side to which heat is directly applied, that is, the temperature on the back side of the panel. The average temperature is 140 degrees Celsius, and the point at which the maximum temperature reaches 180 degrees Celsius is the fire resistance performance time.
대부분의 발포성 내화도료는 유기계 재료를 기반으로 만들어지므로, 실내에 사용되는 제품의 표면에 유기계 재료로 만들어진 종래의 내화도료("유기계 내화도료")를 도포하게 되면, 화재 발생시 유기계 내화도료의 연소로 인하여 실내공기품질에 악영향을 미칠 수 있다. 또한 일반적으로 유기계 내화도료는 5~20mm 정도의 도포 두께를 가지게 되는데, 압출성형 패널 등과 같은 패널 제품에는 이러한 유기계 내화도료의 두꺼운 두께는 적절하지 않을 수 있으며, 경제적 측면에서도 압출성형 패널의 가격 보다 도료의 가격이 더 높아지게 되어 불합리한 상황이 유발되는 문제점이 있다.Since most foamable fire-resistant paints are made based on organic materials, when a conventional fire-resistant paint (“organic fire-resistant paint”) made of organic materials is applied to the surface of a product used indoors, the combustion of the organic fire-resistant paint occurs in the event of a fire. This may have a negative impact on indoor air quality. In addition, organic fire-resistant paints generally have an application thickness of about 5 to 20 mm, but such a thick thickness of organic fire-resistant paints may not be appropriate for panel products such as extruded panels, and from an economic perspective, the paint is cheaper than the price of extruded panels. There is a problem with the price becoming higher, causing an unreasonable situation.
이러한 종래 기술을 대체할만한 기술로서 무기계 내화도료를 사용하는 방안이 적극 고려되고 있다. 대한민국 등록특허 제10-2065560호 및 제10-2362584호에는 매우 유용한 무기계 도료 조성물 및 이와 관련된 기술이 개시되어 있는데, 이들 종래 기술은 주로 전자파 차폐를 주된 목적으로 하는 것이어서, 내화성능 향상과는 다소 거리가 있다. The use of inorganic fire-resistant paints is being actively considered as a technology that can replace these conventional technologies. Republic of Korea Patent Nos. 10-2065560 and 10-2362584 disclose very useful inorganic paint compositions and related technologies, but these prior technologies are mainly aimed at shielding electromagnetic waves, and are somewhat far from improving fire resistance. There is.
한편, 이러한 내화도료의 사용이 절실히 필요한 제품으로는 압출성형 패널이 있다. 대한민국 등록특허 제10-2186229호에는 볏짚을 이용하여 제작됨으로써 우수한 품질과 높은 경제성을 가지는 압출성형 시멘트 패널이 개시되어 있다. 이러한 종래 기술의 패널을 포함하는 다양한 시멘트계 압출성형 패널에 대해서도 높은 내화성능을 가질 것이 요구되고 있는데, 그 표면에 내화도료를 도포하는 것만으로는 원하는 정도의 충분한 내화성능을 구현하는데에는 상당한 애로사항이 있는 바, 압출성형 패널 자체의 내화성능을 향상시킬 필요가 있다. 일본 공개특허 제2022-113645호에는 반응성 내열 조성물을 이용하여 적층 패널을 제조하는 기술이 개시되어 있지만, 이러한 외국의 기술은 시멘트계 압출성형 패널에 적용하기가 사실상 불가능하다는 한계가 있다. Meanwhile, products that desperately need the use of such fire-resistant paints include extruded panels. Republic of Korea Patent No. 10-2186229 discloses an extrusion molded cement panel that is manufactured using rice straw and has excellent quality and high economic efficiency. Various cement-based extrusion panels, including these panels of the prior art, are also required to have high fire resistance performance, but there are significant difficulties in realizing sufficient fire resistance performance to the desired level simply by applying fire resistance paint to the surface. As such, there is a need to improve the fire resistance of the extruded panel itself. Japanese Patent Publication No. 2022-113645 discloses a technology for manufacturing a laminated panel using a reactive heat-resistant composition, but this foreign technology has a limitation in that it is virtually impossible to apply to cement-based extrusion panels.
본 발명은 위와 같은 종래 기술의 한계를 극복하기 위하여 개발된 것으로서, 무기계 재료(구체적으로는 무기계 분말)를 포함하는 조성을 가지고 있어서 제작 비용이 저렴하면서도, 도료로서 압출성형 패널 등의 제품 표면에 도포되었을 때 우수한 내화성능을 발휘할 수 있는 무기계 내화도료 조성물을 제공하는 것을 목적으로 한다. The present invention was developed to overcome the limitations of the prior art as described above. It has a composition containing inorganic materials (specifically, inorganic powders), so it is inexpensive to manufacture, and can be applied as a paint to the surface of products such as extruded panels. The purpose is to provide an inorganic fire-resistant paint composition that can exhibit excellent fire-resistant performance.
특히 본 발명은 압출성형 패널에 도포되기에 적합하며, 압출성형 패널에 도포되었을 때 압출성형 패널이 월등하게 연장된 내화성능 시간을 발휘할 수 있게 만드는 무기계 내화도료 조성물을 제공하는 것을 목적으로 한다. In particular, the present invention aims to provide an inorganic fire-resistant coating composition that is suitable for application to extrusion-molded panels and allows the extruded panels to exhibit significantly extended fire resistance performance time when applied to the extrusion-molded panels.
더 나아가 본 발명은 위와 같은 무기계 내화도료 조성물이 표면에 도포됨으로써 내화성능을 발휘할 뿐만 아니라, 압출성형 패널을 이루는 섬유가 내열성이 우수한 것으로 교체된 구성을 가짐으로써 패널 자체적으로 발휘되는 내화성능이 크게 향상된 압출성형 패널을 제공하는 것을 목적으로 한다. Furthermore, the present invention not only exhibits fire resistance performance by applying the above inorganic fire resistant paint composition to the surface, but also has a structure in which the fibers that make up the extruded panel are replaced with ones with excellent heat resistance, thereby greatly improving the fire resistance performance of the panel itself. The purpose is to provide an extruded panel.

The inorganic fire-resistant paint composition according to the present invention exhibits very excellent fire resistance performance, and the extrusion-molded panel according to the present invention contains hemp fibers with excellent heat resistance, so the inorganic fire-resistant paint composition of the present invention is used in the extrusion-molded panel of the present invention. When applied to the surface, the inorganic fire-resistant paint composition primarily blocks heat and delays the temperature rise of the extruded panel, and secondarily, heat transfers to the area left as a void by burning the fibers in the extruded panel. As the rapidly progressing phenomenon is blocked through the excellent heat resistance of the hemp fiber contained in the extrusion molded panel, the extrusion molded panel exhibits excellent heat resistance performance and ensures sufficient heat resistance performance time required to combat fire. The advantage of being able to do this is demonstrated.
특히, 본 발명의 무기계 내화도료 조성물은, 50mm 두께의 압출성형 패널의 표면에 바름두께 2~3mm로 도포되었을 때, 압출성형 패널의 내화성능 시간을 기존의 30~35분 수준을 60분 이상으로 향상시키게 되며, 도료로서의 발림성이 우수할 뿐만 아니라, 도장 시 갈라짐이 없으며 우수한 내후성을 발휘하게 되는 장점이 있다. In particular, the inorganic fire-resistant paint composition of the present invention, when applied to the surface of a 50 mm thick extruded panel with an application thickness of 2 to 3 mm, increases the fire resistance performance time of the extruded panel from the existing 30 to 35 minutes to 60 minutes or more. It not only has excellent spreadability as a paint, but also has the advantage of not cracking during painting and exhibiting excellent weather resistance.
또한 본 발명의 무기계 내화도료 조성물은 고가의 유기계 내화도료 조성물에 비하여 경제성, 장기 저장성, 및 친환경성이 우수하고, 내화성과 시공성 면에서도 매우 유리한 장점을 가지며, 건축환경기준에도 부합된다는 장점을 가진다.

도 1은 본 발명의 실시예와 비교예에 대하여 측정한 내화성능 비교 그래프도이다. Figure 1 is a graph comparing fire resistance performance measured for Examples and Comparative Examples of the present invention.
이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명한다. Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings.
본 발명에 따른 무기계 내화도료 조성물은, 밀드 카본 5 - 15중량%, 마이카 10 - 25중량%, 알루미나 분말 1 - 5중량%, 무기 바인더 20 - 35중량%, 분산제 2.5 - 4.5중량%, 계면활성제 0.5 - 1.5중량%, 및 물 35 - 45중량%를 포함하는 조성을 가진다. The inorganic fireproof paint composition according to the present invention contains 5 - 15% by weight of milled carbon, 10 - 25% by weight of mica, 1 - 5% by weight of alumina powder, 20 - 35% by weight of inorganic binder, 2.5 - 4.5% by weight of dispersant, and surfactant. It has a composition comprising 0.5 - 1.5% by weight, and 35 - 45% by weight water.
밀드 카본(Milled Carbon)은 실 형태의 카본 섬유를 분말형태로 분쇄한 것, 즉 미분말 형태의 카본 섬유로서, 본 발명의 무기계 내화도료 조성물에서 밀드 카본은 내열성 필러재로서의 기능과 시공성 향상을 위하여 점성을 감소시키는 기능을 한다. 본 발명에서 밀드 카본은 무기계 내화도료 조성물의 총 중량 100중량% 중에서 5 내지 15중량%로 함유된다. 밀드 카본의 함유량이 5중량% 미만이면 도료로서의 점성이 과도하게 높아져서 시공성이 떨어지며 도장 후 건조 과정에서 표면 갈라짐 현상이 일어날 수 있다. 밀드 카본의 함유량이 15중량%를 초과하게 되면 과도한 섬유상 물질의 중첩으로 도료 특성이 저하된다. 본 발명에서 특별히 바람직한 밀드 카본의 함유량은 13.0중량%이다. 밀드 카본의 평균 섬유 길이는 20~80μm인 것이 바람직한데, 비표면적이 작아 점성 감소에 효과적일 수 있는 평균 길이 50~80μm인 밀드 카본을 사용하는 것이 가장 바람직하다. 바람직한 밀드 카본의 물리적 특징은 아래의 표 1과 같다. 본 발명에서 밀드 카본으로는 재활용된 재생제품을 사용할 수도 있다. Milled carbon is carbon fiber in the form of fine powder, which is obtained by pulverizing thread-shaped carbon fiber into powder form. In the inorganic fire-resistant paint composition of the present invention, milled carbon functions as a heat-resistant filler material and has a viscosity to improve constructability. It functions to reduce. In the present invention, milled carbon is contained in an amount of 5 to 15% by weight out of 100% by weight of the total weight of the inorganic fireproof paint composition. If the content of milled carbon is less than 5% by weight, the viscosity of the paint increases excessively, resulting in poor workability, and surface cracking may occur during the drying process after painting. If the content of milled carbon exceeds 15% by weight, the paint properties deteriorate due to excessive overlap of fibrous materials. The particularly preferred content of milled carbon in the present invention is 13.0% by weight. The average fiber length of milled carbon is preferably 20 to 80 μm, but it is most desirable to use milled carbon with an average length of 50 to 80 μm, which has a small specific surface area and can be effective in reducing viscosity. The physical characteristics of preferred milled carbon are shown in Table 1 below. In the present invention, recycled products can also be used as milled carbon.
본 발명에 따른 무기계 내화도료 조성물에는 마이카가 포함되는데, 마이카는 무기계 내화도료 조성물의 총 중량 100중량% 중에서 10 내지 25중량%로 함유된다. 마이카의 함유량이 10중량% 미만이면 내열성능이 저하되어 압출성형 패널의 내열성을 보강할 수 있는 내화 도료로서의 요구성능을 만족시키지 못할 수 있다. 마이카의 함유량이 25중량%를 초과하게 되면 도료의 점성이 높아져 시공성이 떨어지며 바인더가 받아들일 수 있는 양을 초과하게 되어 도장 후 표면 마감이 거칠게 되고, 바인더에 혼합되고 남은 마이카의 잔량이 도장면 위로 떠서 접촉 시 묻어나는 현상이 발생할 수 있다. 본 발명에서 특별히 바람직한 마이카의 함유량은 12.0중량%이다. 마이카를 밀드 카본과 혼합하여 사용함에 있어서, 마이카와 밀드 카본은 중량비로서 거의 1:1(정확하게는 0.9:1)로 포함되는 것이 가장 바람직하다. 마이카의 함유량에 비해 밀드 카본의 함유량이 크면 열전달 차단 효과가 낮아질 수 있다. The inorganic fireproof paint composition according to the present invention contains mica, and mica is contained in 10 to 25% by weight out of 100% by weight of the total weight of the inorganic fireproof paint composition. If the mica content is less than 10% by weight, heat resistance performance may deteriorate and the required performance as a fire resistance paint that can reinforce the heat resistance of extrusion molded panels may not be satisfied. If the mica content exceeds 25% by weight, the viscosity of the paint increases and workability deteriorates. The amount that the binder can accept is exceeded, resulting in a rough surface finish after painting, and the remaining mica mixed with the binder spills over the painted surface. It may float and smear when touched. A particularly preferable mica content in the present invention is 12.0% by weight. When using mica mixed with milled carbon, it is most preferable that mica and milled carbon are included in a weight ratio of approximately 1:1 (0.9:1 to be exact). If the milled carbon content is large compared to the mica content, the heat transfer blocking effect may be reduced.
본 발명에서 알루미나 분말은 무기계 내화도료 조성물의 총 중량 100중량% 중에서 1 내지 5중량%로 함유된다. 알루미나 분말은 무기계 내화 도료에서 열성능을 차단하는 역할을 한다기 보다는 온도가 높아지는 상황에서도 물리적 특성을 상실하지 않아 도료 자체의 보형성 및 탈락을 방지할 수 있는 기능을 한다. 알루미나 분말의 함유량이 1중량% 미만이면 부착성 기능이 낮아지며, 5중량%를 초과하게 되면 경제성을 상실한다. 알루미나 분말은 2.5중량%로 함유되는 것이 특히 바람직하다. In the present invention, alumina powder is contained in an amount of 1 to 5% by weight based on 100% by weight of the total weight of the inorganic fireproof paint composition. Rather than playing a role in blocking the thermal performance of inorganic refractory paints, alumina powder does not lose its physical properties even when the temperature rises, and thus functions to maintain the paint itself and prevent it from falling off. If the content of alumina powder is less than 1% by weight, the adhesive function is lowered, and if it exceeds 5% by weight, economic feasibility is lost. It is particularly preferable that the alumina powder is contained at 2.5% by weight.
무기(無機) 바인더는 혼합 실리케이트를 주성분으로 하는 것으로서, 본 발명에서 무기 바인더는 무기계 내화도료 조성물의 총 중량 100중량% 중에서 20 내지 35중량%로 함유된다. 무기 바인더의 함유량이 20중량% 미만이면, 하지면에 대한 도막의 부착성이 저하되며, 35중량%를 초과하게 되면 도료의 내열성능이 저하된다. 바람직한 무기 바인더의 함유량은 25.5중량%이다. 무기 바인더로서는 액상 규산나트륨을 사용할 수 있다. The inorganic binder is mainly composed of mixed silicates, and in the present invention, the inorganic binder is contained in an amount of 20 to 35% by weight out of 100% by weight of the total weight of the inorganic fireproof paint composition. If the content of the inorganic binder is less than 20% by weight, the adhesion of the coating film to the substrate decreases, and if the content of the inorganic binder exceeds 35% by weight, the heat resistance performance of the paint decreases. The preferred content of inorganic binder is 25.5% by weight. Liquid sodium silicate can be used as an inorganic binder.
본 발명에서 분산제는 무기계 내화도료 조성물의 총 중량 100중량% 중에서 2.5 내지 4.5중량%로 함유된다. 분산제의 함유량이 2.5중량% 미만이면 마이카, 밀드 카본 및 알루미나 분말이 혼합된 혼합물의 분산이 잘 이루어지지 않아 도료로서의 품질이 낮아지며, 4.5중량%를 초과하게 되면 점성이 낮아져 시공이 어려워지고 내화성능도 저하되는 현상이 발생한다. 본 발명에서는 분산제는 4.3중량%로 사용하는 것이 가장 바람직하다. In the present invention, the dispersant is contained in an amount of 2.5 to 4.5% by weight based on 100% by weight of the total weight of the inorganic fireproof paint composition. If the dispersant content is less than 2.5% by weight, the mixture of mica, milled carbon, and alumina powder is not dispersed well, which lowers the quality of the paint. If it exceeds 4.5% by weight, the viscosity decreases, making construction difficult, and fire resistance also decreases. A deterioration phenomenon occurs. In the present invention, the dispersant is most preferably used at 4.3% by weight.
본 발명에서 계면활성제는 무기계 내화도료 조성물의 총 중량 100중량% 중에서 0.5 내지 1.5중량%로 함유된다. 계면활성제는 부분적으로 존재하는 소수성 물질의 분산과 도료의 윤활성 확보를 위하여 사용되는데, 계면활성제의 함유량이 0.5중량% 미만이면 전체 혼합물이 충분히 분산되지 않아 도료의 품질 및 시공성이 낮아지고, 마이카, 알루미나 분말 및 밀드 카본이 혼합된 혼합물의 조직을 치밀하게 해주지 못하기 때문에 내열성능이 저하된다. 계면활성제의 함유량이 1.5중량%를 초과하게 되면 혼합물을 분산시키고 남은 잔여 계면활성제로 인하여 내화성능이 저하되는 현상이 발생할 수 있다. 본 발명에 따른 계면활성제의 최적 함유량은 1.0중량%이다. In the present invention, the surfactant is contained in an amount of 0.5 to 1.5% by weight out of 100% by weight of the total weight of the inorganic fireproof paint composition. Surfactants are used to disperse partially existing hydrophobic substances and ensure the lubricity of the paint. If the surfactant content is less than 0.5% by weight, the entire mixture is not sufficiently dispersed, which lowers the quality and workability of the paint, and mica and alumina Since the structure of the mixture of powder and milled carbon cannot be made dense, heat resistance performance is reduced. If the surfactant content exceeds 1.5% by weight, fire resistance performance may deteriorate due to residual surfactant remaining after dispersing the mixture. The optimal content of surfactant according to the present invention is 1.0% by weight.
본 발명에서는 압출성형 패널의 내열성을 위하여 상기한 본 발명의 무기계 내화도료 조성물을 압출성형 패널의 표면에 도포하게 된다. 이를 통해서 압출성형 패널의 표면에 대하여 효과적인 내열성능 확보가 가능하게 된다. In the present invention, the inorganic fire-resistant paint composition of the present invention described above is applied to the surface of the extrusion-molded panel to improve the heat resistance of the extrusion-molded panel. Through this, it is possible to secure effective heat resistance performance on the surface of the extruded panel.
다음에서는 본 발명의 실시예와 비교예를 설명한다. 아래의 표 2는 본 발명의 실시예와 비교예의 조성을 정리한 것이다. 도 1에는 상기한 본 발명의 실시예와 비교예에 대하여 측정한 내열성 결과를 보여주는 그래프도가 도시되어 있다. In the following, examples and comparative examples of the present invention will be described. Table 2 below summarizes the compositions of the examples and comparative examples of the present invention. Figure 1 shows a graph showing heat resistance results measured for the examples and comparative examples of the present invention described above.
본 발명에 따른 실시예 및 이와 대비되는 비교예에 대한 특성 평가를 위해서 실시예와 비교예 모두에 대해 ISO 834-1 표준에 제시되어 있는 시험 방법 및 성능 평가 규격에 따라 가열온도를 제시하고, 압출성형 패널의 이면온도가 섭씨 260도에 도달하는 시점을 성능 상실 기준 즉, 내화성능 시간으로 설정하여 시험을 진행하였다. 또한 도료로서의 성능 확보를 위하여 KS 표준의 수성도료 성능 평가 기준에 따른 시험을 실시하여 주도, 비휘발분, 건조시간, 은폐율. 내세척성, 광택, 용기 내에서의 상태, 내 알칼리성 등을 평가하여 도료로서의 기본적인 성능 충족도를 확인하였다. 실시예와 비교예에서 무기 바인더로는 액상 규산나트륨을 사용하였다. 또한 실시예와 비교예에서 도료 조성물은 50mm 단판의 압출성형 패널의 표면에 2mm 두께로 도포하여 실험을 수행하였다. In order to evaluate the characteristics of the examples and comparative examples according to the present invention, the heating temperature was presented according to the test method and performance evaluation standard presented in the ISO 834-1 standard for both examples and comparative examples, and extrusion The test was conducted by setting the time when the back temperature of the molded panel reached 260 degrees Celsius as the performance loss standard, that is, the fire resistance performance time. In addition, to ensure performance as a paint, tests were conducted according to the KS standard's water-based paint performance evaluation criteria to determine the percentage of lead, non-volatile content, drying time, and hiding rate. Washing resistance, gloss, condition in the container, alkali resistance, etc. were evaluated to confirm the basic performance as a paint. In the examples and comparative examples, liquid sodium silicate was used as an inorganic binder. Additionally, in Examples and Comparative Examples, the paint composition was tested by applying it to a thickness of 2 mm on the surface of a 50 mm veneer extrusion panel.
위 표 2에서 비교예1,2는, 대한민국 등록특허공보 제10-0458587호에 제시된 성분을 조정하여 적용한 것으로서 SiO2 성분 보강으로 실리카 분말을 사용하였으며, 알루미나 성분은 분말을 그대로 적용하였다. 알루미나의 경우 비용이 고가이기 때문에 적용에 한계가 있다. 특히, 실시예2는 밀드 카본과 마이카가 중량비로서 0.9:1로 함유된 것이고, 실시예1, 3 경우는 밀드 카본과 마이카의 중량비가 상이한 것이다. In Table 2 above, Comparative Examples 1 and 2 were applied by adjusting the components presented in Korean Patent Publication No. 10-0458587, and silica powder was used to reinforce the SiO 2 component, and the alumina component was applied as is. In the case of alumina, its application is limited because it is expensive. In particular, Example 2 contains milled carbon and mica at a weight ratio of 0.9:1, and Examples 1 and 3 contain different weight ratios of milled carbon and mica.
위의 표 2 및 도 1에 정리된 바와 같이, 비교예1,2의 경우 초기 30분대에서 압출성형 패널의 이면 온도 섭씨 273도에 도달하는 시간 즉, 내화성능 시간이 60분에 미치지 못하였지만 본 발명의 실시예1,2,3은 모두 내화성능 시간이 60분을 초과하는 것으로 측정되었다. 이는 본 발명에 따른 무기계 내화도료 조성물의 실시예1, 실시예2, 실시예3 모두가 비교예1 내지 2에 비하여 매우 우수한 내열성능을 발휘하고 있음을 확인해주는 것이다. As summarized in Table 2 and Figure 1 above, in the case of Comparative Examples 1 and 2, the time to reach the back temperature of the extrusion panel at 273 degrees Celsius in the initial 30 minutes, that is, the fire resistance performance time, did not reach 60 minutes, but this Examples 1, 2, and 3 of the invention were all measured to have fire resistance performance times exceeding 60 minutes. This confirms that Examples 1, 2, and 3 of the inorganic fire-resistant paint composition according to the present invention all exhibit very excellent heat resistance performance compared to Comparative Examples 1 and 2.
한편, 무기계 내화도료 조성물에서 발림성과 도장시 갈라짐 발생여부는 모두 시공성과 관련이 있는 물리적 성능으로서 이는 도료 조성물을 시공한 후 부착 상태의 유지 성능을 좌우하게 된다. 위의 표 2에 정리된 바와 같이, 도료 조성물 시공 후의 부착 강도 측정치에 있어서, 실리카 분말과 벤토나이트를 사용한 비교예1, 2 경우보다, 밀드 카본과 마이카 등을 사용한 실시예1,2,3의 특성값이 2배 이상 높은 것으로 나타났다. Meanwhile, in inorganic fire-resistant paint compositions, spreadability and whether or not cracks occur during painting are both physical performances related to workability, which determine the ability to maintain the attached state after applying the paint composition. As summarized in Table 2 above, in terms of adhesion strength measurements after applying the paint composition, the characteristics of Examples 1, 2, and 3 using milled carbon and mica were higher than those of Comparative Examples 1 and 2 using silica powder and bentonite. The value was found to be more than twice as high.
표 3은 한국산업표준에서 규정하는 수성도료의 물리적 성능 기준과, 본 발명의 상기한 실시예1에서 측정된 물리적 성능을 정리한 것으로서, 본 발명의 실시예는 한국산업표준에서 규정하는 수성도료의 물리적 성능 기준을 모두 충족하는 것으로 나타났다. Table 3 summarizes the physical performance standards of water-based paints specified in the Korean Industrial Standard and the physical performance measured in Example 1 of the present invention. The Examples of the present invention are those of water-based paints specified in the Korean Industrial Standards. It was found to meet all physical performance criteria.
이와 같이, 본 발명에 따른 무기계 내화도료 조성물을 50mm 단판의 압출성형 패널의 표면에 2mm 두께로 도포하였을 경우, 60분 이상의 내화성능 시간의 우수한 성능을 보이며, 발림성이 우수하고, 도장 시 갈라짐이 없어 도료로서의 사용성을 충분히 나타내었다. 특히, 본 발명에 따른 무기계 내화도료 조성물은 고가의 금속 조성물을 사용한 종래의 도료에 비하여 경제성, 장기 저장성이 우수하고, EMP 차폐성능, 유기계 도장에 비해서도 경제성 등 유리한 장점을 가지며, 건축환경기준에도 부합된다는 장점을 가진다. In this way, when the inorganic fire-resistant paint composition according to the present invention is applied to the surface of a 50 mm veneer extrusion panel with a thickness of 2 mm, it shows excellent fire resistance performance of more than 60 minutes, has excellent spreadability, and does not crack during painting. It showed sufficient usability as a paint. In particular, the inorganic fire-resistant paint composition according to the present invention is superior in economic efficiency and long-term storage compared to conventional paints using expensive metal compositions, has advantageous advantages such as EMP shielding performance and economic efficiency compared to organic paints, and meets building environment standards. It has the advantage of being
한편, 본 발명에 따른 압출성형 패널은, 그 표면에 상기한 본 발명의 무기계 내화도료 조성물이 도포된다는 특징뿐만 아니라, 압출성형 패널을 이루는 성분 중의 하나인 섬유로서, 내화성이 우수한 마(麻) 섬유를 사용한다는 특징을 가진다. 즉, 종래의 압출성형 패널에 사용하던 폴리프로필렌 섬유, 볏짚 등의 종전 보강섬유를 대체하여 마 섬유를 보강섬유로서 사용하는 것이다. 이 때, 마 섬유는 길이 6~10mm, 두께 0.1~0.2mm를 가지도록 만들어진 것을 이용하는 것이 바람직하다. On the other hand, the extrusion-molded panel according to the present invention not only has the feature that the inorganic fire-resistant paint composition of the present invention described above is applied to its surface, but is also a fiber that is one of the components that make up the extrusion-molded panel, and is a hemp fiber with excellent fire resistance. It has the characteristic of using . In other words, hemp fiber is used as a reinforcing fiber, replacing existing reinforcing fibers such as polypropylene fiber and rice straw used in conventional extrusion panels. At this time, it is desirable to use hemp fibers made to have a length of 6 to 10 mm and a thickness of 0.1 to 0.2 mm.
마 섬유가 기존 보강섬유를 대체하여 사용된다는 본 발명의 특징을 제외하고, 기타 본 발명의 압출성형 패널의 성분 및 함유량은 대한민국 공개특허공보 제10-2020-0061768호에 개시된 내용을 참조할 수 있다. Except for the feature of the present invention that hemp fibers are used to replace existing reinforcing fibers, other components and contents of the extruded panel of the present invention can refer to the information disclosed in Korean Patent Publication No. 10-2020-0061768. .
위에서 살펴본 바와 같이 본 발명에 따른 무기계 내화도료 조성물은 매우 우수한 내화성능을 발휘하며, 본 발명에 따른 압출성형 패널은 내열성이 우수한 마 섬유를 포함하고 있는 바, 본 발명의 무기계 내화도료 조성물이 표면에 도포된 본 발명의 압출성형 패널은, 1차적으로 무기계 내화도료 조성물이 열을 차단하여 압출성형 패널의 온도 상승이 지연된다. 그리고 2차적으로는 높은 연소온도를 가지는 마 섬유의 사용에 의해서 보강섬유의 섬유 연소 방지와 이를 통한 고열의 이동 차단 효과가 발휘되어 압출성형 패널의 내화성능을 크게 향상시키게 된다. 즉, 종래의 폴리프로필렌 섬유 등을 보강섬유로 사용하던 기존 압출성형 패널에서 보강섬유가 연소되어 공극으로 남는 부분으로 열전달이 빠르게 진행되는 현상을, 본 발명에서는 압출성형 패널에 함유되어 있는 마 섬유가 우수한 내열성을 통해서 차단시키게 되는 것이며, 이를 통해서 본 발명의 압출성형 패널은 우수한 내열 성능을 발휘하게 되며, 화재에 대항하기 위하여 요구되는 내열성능 시간을 충분히 확보할 수 있게 된다. As seen above, the inorganic fire-resistant paint composition according to the present invention exhibits very excellent fire resistance performance, and the extruded panel according to the present invention contains hemp fibers with excellent heat resistance, so the inorganic fire-resistant paint composition of the present invention is applied to the surface. In the applied extrusion-molded panel of the present invention, the inorganic fire-resistant paint composition primarily blocks heat, thereby delaying the temperature rise of the extrusion-molded panel. Secondly, the use of hemp fibers, which have a high combustion temperature, prevents combustion of reinforcing fibers and blocks the movement of high heat, greatly improving the fire resistance of extruded panels. In other words, in the existing extrusion molded panel that used conventional polypropylene fibers, etc. as reinforcing fibers, heat transfer progresses rapidly to the area where the reinforcing fibers are burned and remain as voids. In the present invention, hemp fibers contained in the extrusion molded panel are used as reinforcing fibers. It is blocked through excellent heat resistance, and through this, the extrusion molded panel of the present invention exhibits excellent heat resistance performance and can secure the heat resistance performance time required to fight fire.
