Description

내외장재용 합성패널 제조방법 및 이를 이용하여 제조된 내외장재용 합성패널{Composite panel manufacturing method for interior and exterior materials and composite panel for interior and exterior materials}Composite panel manufacturing method for interior and exterior materials and composite panel for interior and exterior materials manufactured using the composite panel manufacturing method for interior and exterior materials

본 발명은 내외장재용 합성패널을 제조하는 방법과 이를 이용한 합성패널에 관한 것으로서, 보다 상세하게 설명하면, 외관을 미려하게 하는 세라믹 재질로 이루어진 표면층과 상기 표면층의 하부에 유리 또는 폐유리 재질로 이루어진 발포유리층이 일체화되도록 하여 경량, 방음, 단열, 난연성이 향상된 내외장재용 합성패널 제조방법 및 이를 이용하여 제조된 내외장재용 합성패널에 관한 기술분야이다.The present invention relates to a method of manufacturing a composite panel for interior and exterior materials and to a composite panel using the same, and in more detail, a surface layer made of a ceramic material to enhance the appearance and a foam made of glass or waste glass material under the surface layer This is a technical field related to a method for manufacturing a composite panel for interior and exterior materials with improved light weight, sound insulation, heat insulation, and flame retardancy by allowing the glass layer to be integrated, and a composite panel for interior and exterior materials manufactured using the same.

일반적으로, 내외장재용 패널은 주로 암면, 석고보드, 유리섬유, 스티로폼 등 단열재와 압축목재와 접착제로 구성된 하드보드 등이 사용되고 있으나, 이러한 판재들은 인체에 유해한 물질을 배출하는 것으로 알려져 있으며 또한 재활용이 불가능하여 환경공해를 일으키는 등의 문제점이 있다.In general, panels for interior and exterior materials are mainly used as insulation materials such as rock wool, gypsum board, glass fiber, and styrofoam, and hard boards made of compressed wood and adhesives, but these boards are known to emit substances harmful to the human body and cannot be recycled. Therefore, there are problems such as causing environmental pollution.

이에 따라 현장에서는 건축물의 외장재로 세라믹 재질의 패널을 많이 사용하고 있고, 상기 세라믹 재질의 패널 중 저렴하면서도 미려한 미관을 형성할 수 있는 타일의 사용이 점차 늘어나고 있는 추세이다.Accordingly, in the field, ceramic panels are widely used as exterior materials of buildings, and among the ceramic panels, the use of tiles capable of forming a beautiful appearance while being inexpensive is gradually increasing.

상기와 같은 타일은 종래에 도기나 자기의 형태로 제조되어 공급되고 있으나 재료 자체의 조직 치밀성이 매우 높아 단열성을 발현시킬 수 없고, 다공성 재료의 타일을 만들어질 수 없기 때문에 단열 특성을 갖는 타일의 개발과 제조에 많은 어려움을 겪어 왔으며, 현재까지 단열재의 표면에 유리질의 유약 또는 도포제로 코팅한 다음 높은 온도에서 소성하여 단열 특성이 있는 타일을 제조하였으나 공정상의 어려움 및 생산 에너지 비용 등으로 인해 가격이 높아 대중적으로 활용되기 어려운 실정이다.Tiles such as the above are conventionally manufactured and supplied in the form of pottery or porcelain, but the material itself has very high organizational density, so it cannot exhibit heat insulation, and it is not possible to make tiles made of porous materials. It has suffered a lot of difficulties in manufacturing and, until now, the surface of the insulation material was coated with a glassy glaze or a coating agent and then fired at a high temperature to produce a tile with insulation properties, but the price is high due to process difficulties and production energy costs. It is difficult to use in the public.

한편, 발포유리(foamed glass)는 아주 미세하게 분쇄된 특수한 조성을 갖는 유리에 발포제를 혼합하여 열처리한 무기질 유리로서 세포성 유리(cellular glass) 또는 다세포성 유리(multicellular glass)로 불리워진다.On the other hand, foamed glass is an inorganic glass that is heat-treated by mixing a foaming agent with glass having a very finely pulverized special composition and is called cellular glass or multicellular glass.

상기와 같은 발포유리는 경량이면서 불꽃차단, 단열, 내열, 흡음 등에 탁월한 성능을 발휘하여 산업상 방수, 내열성, 내구성이 요구되는 경우에 사용되며, 특히 구조물이나 건축물에 있어서 훌륭한 보온단열재 및 흡음재로 사용되고 있다.Foamed glass as described above is lightweight and exhibits excellent performance in flame protection, heat insulation, heat resistance, sound absorption, etc., and is used when industrial waterproofing, heat resistance, and durability are required.In particular, it is used as an excellent thermal insulation material and sound absorbing material in structures or buildings. have.

발포유리의 제조 원리는 1930년대 후반에 이미 제안된 바 있다. 그 일례로서 특별한 조성의 유리에 탄소와 같은 환원제와 산화물, 설페이트(sulfate) 또는 다른 형태의 산화성분들을 함유하는 기포형성제를 함께 혼합하여 이를 분쇄한 후, 이 분쇄된 혼합물을 일정한 용기 또는 틀에 넣어 연화 또는 용융 전까지 소성시키는 것이다.The manufacturing principle of foamed glass had already been proposed in the late 1930s. As an example, after mixing together a reducing agent such as carbon and a bubble-forming agent containing oxides, sulfates, or other types of oxidizing components in glass of a special composition and pulverizing it, the pulverized mixture is placed in a certain container or frame. Put it and fire it until softening or melting.

이 열처리 과정에서 탄소와 황산화물(또는 산화제 또는 유리의 산화물) 사이에 산화-환원반응이 일어나고 그 결과 용융된 유리는 SO2 , CO2 , N2 , H2S 또는 다른 가스를 함유하게 되며 이것이 저밀도이며 열전도 및 복사에 저항이 되는 구조를 형성하게 하는 물질을 만들며 유리가스를 형성한다. 그 결과 가장 최상의 결과를 얻을 경우 유리의 구조는 물 또는 수증기, 또는 다른 액체 및 기체 등이 스며들지 않는 밀폐기공을 갖게 된다.In this heat treatment process, an oxidation-reduction reaction occurs between carbon and sulfur oxides (or oxides of oxidizer or glass), and as a result, the molten glass contains SO 2 , CO 2 , N 2 , H 2 S or other gases. It makes a material that is low-density and that resists heat conduction and radiation, and forms glass gas. As a result, when the best results are obtained, the structure of the glass will have closed pores that are impermeable to water or steam or other liquids and gases.

이와 같은 제조 원리에 따라 제조되는 발포유리 블록의 제조 공정에 대해서는 많은 연구결과 및 관련 특허가 제안된 바 있다. 미국의 피츠버그 코닝(Pittsburg Corning)사에서 상용화한 발포유리를 제조하기 위해서는 일차적으로 특별한 조성의 발포유리 제조용 원료유리를 제조하여야 한다. 이를 위해서 통상의 유리 제조용 원료 성분에다 발포유리가 될 수 있도록 Na2SO4, CaCO3, MgCO3, Na2O, As2O3 등의 여러 성분을 가하여 1300∼1600℃의 용융과정을 거쳐 발포유리를 만들 수 있는 발포유리제조용 원료유리를 만들고 있다. 그리고 이렇게 만들어진 유리를 분쇄하고 여기에 다른 성분과 반응하여 직접적인 발포제 역할을 하는 기체를 생성하는 발포조제인 탄소 등을 첨가하여 잘 혼합한 다음, 이 혼합된 발포유리 제조용 원료유리 분말을 일정한 용기에 담아 400∼650℃에서 예열하고, 800∼900℃의 조건하에서 발포과정을 거친 후 안정화를 위한 냉각, 서냉 등의 열처리 과정을 거친 것을 일정한 크기로 절단하여 포장 판매하고 있다.A number of research results and related patents have been proposed for the manufacturing process of the foamed glass block manufactured according to such a manufacturing principle. In order to manufacture the foamed glass commercialized by Pittsburg Corning of the United States, the raw glass for manufacturing the foamed glass of a special composition must be manufactured. To this end, various ingredients such as Na 2 SO 4 , CaCO 3 , MgCO 3 , Na 2 O, As 2 O 3 are added to the usual raw materials for glass manufacturing to become foamed glass, and foamed through a melting process of 1300 to 1600°C. We are making raw glass for foaming glass that can make glass. Then, the glass thus made is pulverized, and carbon, which is a foaming aid that reacts with other components to generate a gas that acts as a direct blowing agent, is added and mixed well, and the mixed raw glass powder for foaming glass is put in a certain container. After preheating at 400 to 650°C, foaming under conditions of 800 to 900°C, heat treatments such as cooling and slow cooling for stabilization are cut into certain sizes and packaged.

그러나 이 공정은 발포유리 제조용 원료유리를 만드는 과정에서 상기한 바와 같이 열처리 온도가 1300∼1600℃로 되어 다량의 에너지가 소요되고, 그에 따른 시설투자 및 관리비용이 필요하기 때문에, 발포유리 제조용 원료유리의 생산비용이 발포유리 생산원가의 절반 이상을 차지하고 있다. 이에 따라 근래에는 상기와 같이 발포유리 제조용 원료유리를 만드는데 많은 시간과 비용이 필요하여 폐유리를 이용하는 기술이 개발되고 있는 실정이다.However, this process requires a large amount of energy as the heat treatment temperature is 1300 to 1600°C as described above in the process of making the raw glass for foamed glass manufacturing, and thus requires facility investment and management costs. The production cost of is more than half of the production cost of foamed glass. Accordingly, in recent years, a lot of time and cost are required to make a raw glass for manufacturing foamed glass as described above, and thus a technology using waste glass is being developed.

상기와 연관하여, 앞서 설명된 내외장재로 활용되는 타일은 저렴하면서도 미려하기 때문에 건축 현장에서 많이 사용하고 있음에도 불구하고 단열 시공과 타일의 마감공사 시공은 항상 별도의 개념으로 시행되어 왔으며 현재도 이러한 시공 방법을 답습하고 있는 실정이다.In connection with the above, the tiles used as interior and exterior materials described above are inexpensive and beautiful, so even though they are widely used in construction sites, the insulation construction and the finishing of tiles have always been carried out as separate concepts, and these construction methods are still present. The situation is following.

그러나 점차로 요구되는 친환경 제품의 사용 강제화, 에너지 절감 기준의 강화 등에 따라 단열재의 사용이 급격히 늘어갈 것으로 판단되는 반면에 무기 소재에 의한 친환경적인 단열제품은 그 가격이 고가이며, 단열성능이 유기 소재 단열재에 비하여 낮은 단점이 있어 이러한 추세에 적극적으로 부응하지 못하고 있는 현실이다.However, it is estimated that the use of insulation materials will increase rapidly due to the increasingly demanded use of eco-friendly products and strengthening of energy saving standards, while eco-friendly insulation products made of inorganic materials are expensive and have organic insulation performance. It is a reality that it is not able to actively respond to this trend because it has a lower drawback than that of.

이러한 관점에서 볼 때, 발포유리 단열재가 비교적 저렴하기 때문에 유기 단열재를 대체할 수 있는 가장 근접된 대안으로 연구되고 있으나 기존의 용융법으로는 제조 단가가 매우 높아 이를 타일에 적용하여 단열 타일을 제조하기에는 수요처인 산업 현장에서의 경제적 활용과 이용에 큰 걸림돌이 되고 있어 사용이 어려운 문제점이 있다.From this point of view, since foam glass insulation is relatively inexpensive, it is being studied as the closest alternative to organic insulation, but the manufacturing cost is very high with the existing melting method, so it is difficult to manufacture insulation tiles by applying it to tiles. There is a problem that it is difficult to use because it is a big obstacle to economic utilization and use in the industrial field, which is a consumer.

In preparation, as shown in FIG. 2, the ceramic tile 20 is turned over and seated so that the printing layer is located under the molding mold 10.

이때, 상기 세라믹타일(20)을 형성하는 세라믹 재질은 유리분말과 발포재의 혼합재(30)가 발포되어 형성되는 발포층(32)에 상기 세라믹타일(20)이 안정적으로 결합을 유지할 수 있도록 인쇄층의 이면에 도포되는 유약조성물에 유리프릿이 포함되는 것이 바람직하다.At this time, the ceramic material forming the ceramic tile 20 is a printed layer so that the ceramic tile 20 can stably maintain bonding to the foam layer 32 formed by foaming the mixture 30 of the glass powder and the foam material. It is preferable that the glass frit is included in the glaze composition applied to the back side of the glass.

구체적으로, 본 발명의 제1준비단계(S10)는 이미지가 인쇄된 인쇄층이 상부면에 형성된 세라믹 재질(유약 조성물 포함)로 이루어진 세라믹타일(20)을 1.5~20㎜의 두께로 소성하여 준비하고, 성형틀(10)에 인쇄층이 상부면에 형성된 상기 세라믹타일(20)을 안착시키되, 상기 인쇄층이 하부에 위치되도록 안착시켜 최종적으로 제조되어 지는 내외장재용 합성패널의 상부면에 이미지가 인쇄된 인쇄층이 형성될 수 있도록 하는 것을 특징으로 한다.Specifically, the first preparation step (S10) of the present invention is prepared by firing a ceramic tile 20 made of a ceramic material (including the glaze composition) formed on the upper surface of the printed layer on which the image is printed to a thickness of 1.5 to 20 mm. And, the ceramic tile 20 having the printing layer formed on the upper surface is mounted on the molding frame 10, and the image is finally placed on the upper surface of the composite panel for interior and exterior materials produced by placing the printing layer at the bottom. It is characterized in that the printed printing layer can be formed.

부가하여 설명하면, 본 발명의 제1준비단계(S10)는 이후에 자세히 설명될 유리분말과 발포재가 혼합된 혼합재(30)를 발포시켜 형성되는 발포층(32)과 재질이 다른 세라믹타일(20)을 동시에 소성하지 않도록 함으로써, 발포층(32) 또는 세라믹타일(20)에 크랙의 발생을 방지하는 효과를 실현케 한다.In addition, the first preparation step (S10) of the present invention is a ceramic tile 20 having a different material from the foam layer 32 formed by foaming the mixed material 30 in which the glass powder and the foaming material are mixed, which will be described later in detail. ) Is not fired at the same time, thereby realizing the effect of preventing the occurrence of cracks in the foam layer 32 or the ceramic tile 20.

즉, 본 발명의 내외장재용 합성패널은 이후에 자세히 설명될 제2준비단계(S20)와 소성단계(S30)에서 기 성형된 세라믹타일(20)의 하부에 발포층(32)이 형성되도록 함으로써, 세라믹타일(20)이 성형되는 온도까지 소성온도를 높이지 않고 소성되기 때문에 상기 발포층(32)이 파손되는 것을 방지할 수 있는 것이다.That is, in the composite panel for interior and exterior materials of the present invention, the foam layer 32 is formed under the ceramic tile 20 previously formed in the second preparation step (S20) and the firing step (S30) to be described in detail later, Since the ceramic tile 20 is fired without raising the firing temperature to the temperature at which it is molded, the foam layer 32 can be prevented from being damaged.

다음으로, 본 발명의 제2준비단계(S20)는Next, the second preparation step (S20) of the present invention

상기 제1준비단계(S10) 이후의 상기 성형틀(10)에 유리분말과 발포재가 혼합된 혼합재(30)를 채우는 것으로서, 상기 성형틀(10)에 기 성형되어 안착된 세라믹타일(20)의 상부 즉, 세라믹타일(20)의 인쇄층 이면에 이후에 자세히 설명될 소성단계(S30)에서 소성되어 발포되는 발포층(32)이 형성될 수 있도록 발포유리 원료인 유리분말 또는 폐유리분말과 발포재를 채우는 것을 특징으로 한다.Filling the mixed material 30 in which the glass powder and the foaming material are mixed in the molding mold 10 after the first preparation step (S10), and the ceramic tile 20 preformed and seated in the molding mold 10 Foaming with glass powder or waste glass powder as a raw material for foamed glass so that the foam layer 32 that is fired and foamed in the firing step (S30) to be described later in detail can be formed on the upper side, that is, on the back side of the printed layer of the ceramic tile 20 It is characterized by filling ash.

이때, 상기 유리분말은 상기 발포유리 원료인 유리분말의 가격이 고가이므로, 폐유리를 이용한 분말 즉, 폐유리분말을 이용하는 것이 바람직한데, 일반적으로 생활상이나 산업적으로 발생되는 폐유리를 이용하여 발포유리의 제조를 위한 다른 특별한 전처리공정을 거치지 않고 폐유리를 직접 발포시켜 발포유리를 제조하는 것을 특징으로 한다.At this time, since the glass powder is expensive, it is preferable to use a powder using waste glass, that is, a waste glass powder. It is characterized in that the foamed glass is manufactured by directly foaming the waste glass without going through other special pretreatment processes for the manufacture of.

부가하여 설명하면, 상기 유리분말은 발포유리 원료로서의 소듐-실리케이트(sodium-silicate) 또는 보로알루미노-실리케이트(boroalumino-silicate)조성의 폐유리를 간단히 분쇄기 등을 이용하여 분말의 형태로 만든 후 상기 성형틀(10)에 채워 넣는다.In addition, the glass powder is a waste glass composed of sodium-silicate or boroalumino-silicate as a raw material for foamed glass, and then simply made into a powder form using a pulverizer, etc. Fill in the molding mold (10).

덧붙여, 상기 폐유리는 디스크밀, 볼밀 등의 분쇄장치를 이용한 습식분쇄공정으로 분쇄하고, 용매로는 물, 에틸 알코올, 메틸 알코올 및 아세톤으로 이루어지는 군으로부터 선택되는 적어도 하나의 용매를 사용할 수 있으며, 효율적인 분쇄를 위해 복수의 단계 일례로, 1차 건식방법 조분쇄, 2차 습식분쇄방법 미세분쇄를 거쳐 진행될 수 있다. 즉, 앞서 언급된 발포재는 일례로 물이 될 수 있다.In addition, the waste glass is pulverized by a wet pulverization process using a pulverizing device such as a disk mill or a ball mill, and at least one solvent selected from the group consisting of water, ethyl alcohol, methyl alcohol and acetone may be used as a solvent, As an example of a plurality of steps for efficient pulverization, it may be carried out through a first dry method coarse pulverization and a second wet pulverization method fine pulverization. That is, the foam material mentioned above may be water as an example.

발포유리의 생성메카니즘은 아래의 식 1과 같이 진행된다.The mechanism for generating foamed glass proceeds as shown in Equation 1 below.

식 1)Equation 1)

Figure 112019106187614-pat00001
Figure 112019106187614-pat00001

부가하여 설명하면, 식 1에 나타나는 바와 같이, 특정 조성을 가지는 원료유리, 예를 들어 소듐-실리케이트와 같이 상기 식 1의 M이 Na인 경우, 물을 가하면 가수분해에 의하여 물속의 H+이온과 유리의 Na+이온이 서로 교환되며 NaOH 알칼리용액이 형성되게 된다. 다음, NaOH 알칼리 용액의 OH-이온이 유리에 침투하며 SiO2 방목구조를 파괴하게 된다. 이후 소성 발포 공정을 거치면서, 가수분해결과 유리에 함유된 유리상태 수분 또는 OH-성분이 분해되어 연화 또는 용융된 유리입자의 내부에 기포를 형성하게 되고 이와 같이 유리입자 내부에 트랩(trapped)된 결과 유리 내에 기포가 형성되어 발포유리가 된다.In addition, as shown in Equation 1, when M in Equation 1 is Na, such as a raw material glass having a specific composition, for example, sodium-silicate, when water is added, H + ions in water and free from water are hydrolyzed. Na + ions of are exchanged with each other to form NaOH alkali solution. Next, the OH - ions of the NaOH alkali solution penetrate the glass and destroy the SiO 2 grazing structure. After going through the plastic foaming process, as a result of hydrolysis, the glassy moisture or OH - component contained in the glass is decomposed to form bubbles inside the softened or melted glass particles, and thus trapped inside the glass particles. As a result, bubbles are formed in the glass to form a foamed glass.

즉, 앞서 설명된 세라믹타일(20)에 포함된 유리프릿 또한 소듐-실리케이트(sodium-silicate) 또는 보로알루미노-실리케이트(boroalumino-silicate)조성으로 이루어지는 것이 바람직하며, 상기에서 설명된 바와 같이, 이후에 자세히 설명될 소성단계(S30)에서 함께 발포되며 결합되어 안정적인 일체화가 이루어지는 효과를 실현케 한다.That is, the glass frit included in the ceramic tile 20 described above is also preferably made of a sodium-silicate or boroalumino-silicate composition, and as described above, since It is foamed together in the firing step (S30) to be described in detail and is combined to realize the effect of achieving stable integration.

아울러, 상기 발포층(30)은 이후에 자세히 설명될 소성단계(S30)에서 발포된 후 약 3~4㎜의 두께를 갖도록 채워질 수 있으나, 이는 시공조건 및 단열, 방음의 효과를 고려하여 당업자에 의해 다양한 두께 일례로, 100~120㎜ 이상으로 형성될 수 있다.In addition, the foam layer 30 may be filled to have a thickness of about 3 to 4 mm after being foamed in the firing step (S30), which will be described in detail later, but this is considered by those skilled in the art in consideration of construction conditions and effects of heat insulation and sound insulation. As an example of various thicknesses, it may be formed to be 100 to 120 mm or more.
