한지를 이용한 건물의 마감재{finishing materials for floor and wall using korean paper}Finishing materials for buildings using Korean paper {finishing materials for floor and wall using korean paper}

본 발명은 한지를 이용한 건물의 바닥 및 벽면용 마감재에 관한 것으로서, 더욱 상세하게는 건축용 보드의 표면에 가공처리한 한지를 덧붙여 친환경적이면서 내구성이 우수하고 인체 및 내부환경에 유익함과 동시에 표면에 선명한 칼라 패턴을 형성할 수 있어서 미려한 외관을 제공할 수 있는 건물의 바닥 및 벽면용 마감재에 관한 것이다. The present invention relates to a finishing material for floors and walls of buildings using Korean paper, and more specifically, by adding processed Korean paper to the surface of a building board, it is eco-friendly, has excellent durability, is beneficial to the human body and the internal environment, and has a clear appearance on the surface. This relates to finishing materials for floors and walls of buildings that can form color patterns and thus provide an attractive exterior.

일반적으로 건축용 마그네슘 보드(Magnesium Board)난연성과 방수성과 경제성과 보온성 등 장점이 있어 건물의 바닥이나 벽면의 마감재로 많이 사용되고 있다.In general, magnesium board for construction has advantages such as flame retardancy, waterproofing, economics, and thermal insulation, so it is widely used as a finishing material for floors and walls of buildings.

그러나, 건축용 마그네슘 보드는 인장강도와 경도가 약하여 충격에 부서지고 금이 가는 문제점, 흡수율이 높아 발생되는 길이변화로 크랙발생이 잦은 문제점, 햇빛이나 고온에 노출시 심하게 휘어지는 문제점, 경도를 높이고자 시멘트 강화제를 사용하여 냄새가 역겨운 문제점, 유해물질로 인한 피부 따가움과 호흡곤란의 문제점 등이 있다.However, magnesium boards for construction have problems such as breaking and cracking on impact due to weak tensile strength and hardness, frequent cracks due to changes in length due to high water absorption, severe bending when exposed to sunlight or high temperatures, and cement to increase hardness. There are problems such as unpleasant smell due to the use of strengthening agents, skin irritation and breathing difficulties due to harmful substances.

이에 따라 다양한 기능성 마감재나 친환경 마감재에 대한 수요가 증가하고 있다. Accordingly, demand for various functional and eco-friendly finishing materials is increasing.

최근 자연친화적인 마감소재로서 한지가 각광받고 있다. 한지는 원적외선 및 음이온 방출, 탈취능력이 우수하고 인체에 유해한 포름알데히드나 VOC, 환경호르몬 배출이 없는 친환경소재이다.Recently, Hanji has been in the spotlight as an eco-friendly finishing material. Hanji is an eco-friendly material that emits far-infrared rays and negative ions, has excellent deodorizing ability, and does not emit formaldehyde, VOC, or environmental hormones harmful to the human body.

이러한 친환경소재인 한지를 건축용 보드에 접촉한 마감재가 개발되고 있다. 대한민국 공개특허 제10-2011-0102668호에는 황토보드의 표면에 옻칠한지장판을 부착한 한지장판보드가 개시되어 있다.Finishing materials made by contacting construction boards with Hanji, an eco-friendly material, are being developed. Republic of Korea Patent Publication No. 10-2011-0102668 discloses a Korean paper floor board in which a lacquered floor board is attached to the surface of a red clay board.

상기 한지장판보드는 한지를 부착하여 친환경적이다는 장점은 있으나, 단순히 옻칠을 바른 한지만으로는 기능성이 매우 낮다는 단점이 있다. The above-mentioned Korean paper flooring board has the advantage of being environmentally friendly by attaching Korean paper, but has the disadvantage of being very low in functionality with just the Korean paper coated with lacquer.

Figure 2 is a front view of Figure 1,
Figure 3 is a cross-sectional view of the Korean paper sheet applied in Figure 1.

이하, 본 발명의 일 예에 따른 한지를 이용한 건물의 마감재에 대하여 구체적으로 설명한다. Hereinafter, a finishing material for a building using Korean paper according to an example of the present invention will be described in detail.

도 1 내지 도 3을 참조하면, 본 발명의 건물의 마감재(10)는 판상의 보드(11)와, 보드(11)의 표면에 부착되는 한지시트(15)를 구비한다. Referring to Figures 1 to 3, the building finishing material 10 of the present invention includes a plate-shaped board 11 and a Korean paper sheet 15 attached to the surface of the board 11.

보드(11)는 일정한 두께의 판상으로 이루어진다. 보드(11)는 도시된 사각형 외에도 다양한 형태와 크기로 이루어질 수 있음은 물론이다. The board 11 is made of a plate shape with a certain thickness. Of course, the board 11 can be made of various shapes and sizes other than the square shown.

보드(11)로 통상적인 건축용 보드가 사용될 수 있다. 가령, 마그네슘 보드나 황토보드 등 다양한 소재로 형성된 보드가 사용될 수 있다. 바람직하게 보드(11)는 황토포졸란이 함유된 마그네슘 보드일 수 있다. 일 예로 등록특허 제10-2231962호에 개시된 마그네슘 보드를 이용할 수 있다. 이러한 마그네슘 보드는 강도가 우수하고 황토포졸란 성분을 함유하고 있어서 친환경적이면서 인체 및 내부환경에 유익하다. As the board 11, a typical building board can be used. For example, boards made of various materials such as magnesium board or red clay board can be used. Preferably, the board 11 may be a magnesium board containing yellow topozzolan. As an example, the magnesium board disclosed in Patent Registration No. 10-2231962 can be used. This magnesium board has excellent strength and contains yellow pozzolanic ingredients, so it is environmentally friendly and beneficial to the human body and internal environment.

보드(11)는 건물의 바닥 및 벽면에 부착된다. 보드(11)를 건물의 바닥 및 벽면에 부착하기 위해 보드(11)의 하면에는 접착층이 형성될 수 있다. The board 11 is attached to the floor and walls of the building. In order to attach the board 11 to the floor and wall of a building, an adhesive layer may be formed on the lower surface of the board 11.

또한, 보드(11)의 하부에 흡음패드(13)가 부착될 수 있다. 흡음패드(13)는 얇은 두께의 판상으로 이루어진다. 흡음패드(13)는 소음이나 충격을 흡수할 수 있도록 발포수지로 형성될 수 있다. 흡음패드(13)가 보드(11)의 하부에 부착되어 있을 경우, 흡음패드(13)의 하면이 건물의 바닥 및 벽면에 부착된다. Additionally, a sound-absorbing pad 13 may be attached to the lower part of the board 11. The sound-absorbing pad 13 is made of a thin plate shape. The sound-absorbing pad 13 may be made of foam resin to absorb noise or shock. When the sound-absorbing pad 13 is attached to the lower part of the board 11, the lower surface of the sound-absorbing pad 13 is attached to the floor and wall of the building.

한지시트(15)는 보드(11)의 상부에 부착된다. The Korean paper sheet 15 is attached to the top of the board 11.

한지시트(15)는 합지층(16)과, 합지층(16)의 표면에 백색도료를 도포하여 형성시킨 백색도장층(17)과, 백색도장층(17)의 표면에 인쇄되어 특정한 패턴을 형성하는 패턴층(18)과, 패턴층(18)의 표면에 형성되는 코팅층(19)을 구비한다.The Korean paper sheet 15 includes a laminate layer 16, a white painted layer 17 formed by applying white paint to the surface of the laminate layer 16, and a specific pattern printed on the surface of the white painted layer 17. It is provided with a pattern layer 18 to be formed and a coating layer 19 formed on the surface of the pattern layer 18.

합지층(16)은 적어도 2장의 한지(16a)가 겹쳐져 형성된다. 가령, 2장의 한지(16a)를 겹쳐서 형성하거나, 3장 이상의 한지를 겹쳐서 형성할 수 있다. 한지(16a)는 닥나무 펄프로 만들어진 한국 전통의 종이이다. 각각의 한지(16a)에 전분풀(16b)을 바른 다음 한지(16a)를 겹쳐서 합지시킬 수 있다. The laminate layer 16 is formed by overlapping at least two sheets of Korean paper 16a. For example, it can be formed by overlapping two sheets of Korean paper 16a, or by overlapping three or more sheets of Korean paper. Hanji (16a) is a traditional Korean paper made from mulberry pulp. The starch paste 16b can be applied to each Korean paper 16a and then the Korean paper 16a can be overlapped.

한지 차체는 수분에 약하므로 한지(16a)에 식물성 오일을 함침시켜 사용한다. 이를 위해 합지된 한지(16a)를 식물성 오일에 침지시켜 식물성 오일이 한지에 함침되도록 한다. 침지는 6 내지 24시간 동안 수행할 수 있다. 식물성 오일로 대두유와 아마인유를 3:1의 중량비로 혼합한 것을 사용할 수 있다. 식물성 오일을 한지에 충분히 함침시킨 후 합지된 한지를 꺼내서 음지에서 약 10 내지 30일 정도 건조시켜 합지층(16)을 수득할 수 있다. Since the Korean paper car body is weak against moisture, the Korean paper (16a) is impregnated with vegetable oil. For this purpose, the laminated Korean paper 16a is immersed in vegetable oil so that the vegetable oil is impregnated into the Korean paper. Soaking can be carried out for 6 to 24 hours. Vegetable oil can be used by mixing soybean oil and linseed oil in a weight ratio of 3:1. After sufficiently impregnating the Korean paper with vegetable oil, the laminated Korean paper is taken out and dried in the shade for about 10 to 30 days to obtain the laminated layer 16.

이와 같이 식물성 오일이 함침된 합지층(16)은 한지의 강도를 높이며, 방수성을 부여한다. In this way, the composite layer 16 impregnated with vegetable oil increases the strength of the Korean paper and provides waterproofness.

백색도장층(17)은 식물성 오일이 함침된 합지층(16)의 표면에 백색도료를 도포하여 형성시킨다. 합지층(16)과 패턴층(18) 사이에 백색도장층(17)이 형성됨으로써 패턴층(18)에 선명한 칼라 패턴을 구현하기가 용이하다. The white paint layer 17 is formed by applying white paint to the surface of the laminate layer 16 impregnated with vegetable oil. Since the white coating layer 17 is formed between the laminate layer 16 and the pattern layer 18, it is easy to implement a clear color pattern on the pattern layer 18.

백색도료는 베이스 수지에 안료를 혼합하여 얻을 수 있다. 베이스 수지로 천연수지를 사용한다. 천연수지로 곤충의 분비물을 가공하여 만든 셀락(shellac) 수지 또는 옻나무에서 추출한 옻칠을 이용할 수 있다. 셀락 수지 및 옻칠은 상업화된 제품을 구입하여 이용할 수 있다. White paint can be obtained by mixing pigment with base resin. Natural resin is used as the base resin. You can use shellac resin, which is a natural resin made by processing insect secretions, or lacquer extracted from the lacquer tree. Shellac resin and lacquer are available as commercial products.

안료로 무기계 백색안료를 이용한다. 이러한 무기계 백색 안료로 이산화티탄을 들 수 있다. Inorganic white pigment is used as the pigment. Titanium dioxide is an example of such an inorganic white pigment.

베이스 수지의 종류에 따라 백색도료는 2가지로 준비될 수 있다. 가령, 셀락 수지에 백색안료를 혼합한 백색도료와, 옻칠에 백색안료를 혼합한 백색도료를 준비할 수 있다. Depending on the type of base resin, white paint can be prepared in two ways. For example, white paint can be prepared by mixing white pigment with shellac resin and white paint by mixing white pigment with lacquer.

셀락 수지에 백색안료를 혼합한 백색도료를 합지층(16)에 1차로 도포한다. 그리고 1차로 도포된 백색도료가 건조되면 옻칠에 백색안료를 혼합한 백색도료를 그 위에 도포하여 백색도장층(17)을 형성할 수 있다. 옻칠에 백색안료를 혼합한 백색도료는 추가로 1~2회 더 도포할 수 있다. White paint mixed with shellac resin and white pigment is first applied to the laminate layer 16. And when the initially applied white paint dries, white paint mixed with lacquer and white pigment can be applied thereon to form the white paint layer 17. White paint mixed with lacquer and white pigment can be applied one to two additional times.

이와 같이 셀락 수지에 백색안료를 혼합한 백색도료를 도포하고, 그 위에 옻칠에 백색안료를 혼합한 백색도료를 추가로 더 도포하는 방식으로 백색도장층(17)을 형성함으로써 백색도장층(17)의 강도를 높이고 백색도를 향상시킬 수 있다. In this way, the white paint layer 17 is formed by applying white paint mixed with white pigment to shellac resin and additionally applying white paint mixed with white pigment to lacquer on top of the white paint layer 17. It can increase the intensity and improve whiteness.

패턴층(18)은 백색도장층(17)의 표면에 특정한 패턴을 형성한다. 이러한 패턴층(18)은 통상적인 프린팅 방법을 통해 인쇄되어 형성될 수 있다. 패턴층의 인쇄시 자외선 경화형 잉크를 사용한다. 이 경우 자외선을 조사하여 빠른 시간에 패턴층을 경화시킬 수 있다. The pattern layer 18 forms a specific pattern on the surface of the white painting layer 17. This pattern layer 18 can be formed by printing using a conventional printing method. When printing the pattern layer, ultraviolet curable ink is used. In this case, the pattern layer can be cured quickly by irradiating ultraviolet rays.

패턴층(18)의 패턴은 다양한 무늬와 다양한 색상으로 이루어질 수 있다. 특히, 백색도장층(17)에 형성되는 패턴층(18)은 백색과 대비되는 선명한 칼라 색상의 패턴을 연출할 수 있다. The pattern of the pattern layer 18 may have various patterns and colors. In particular, the pattern layer 18 formed on the white painting layer 17 can produce a vivid color pattern that contrasts with white.

코팅층(19)은 패턴층(18)의 표면에 형성된다. 코팅층(19)은 한지시트(15)의 최상부층을 이루는 것으로서, 한지시트(15)를 외부로부터 보호하는 역할을 한다. The coating layer 19 is formed on the surface of the pattern layer 18. The coating layer 19 forms the uppermost layer of the Korean paper sheet 15 and serves to protect the Korean paper sheet 15 from the outside.

코팅층(19)은 코팅제를 패턴층(18)의 표면에 1회 또는 2회 내지 3회 도포하여 형성시킬 수 있다. 코팅제로 물리적 성능을 개선하고 상온 경화 및 높은 내열성을 제공하는 투명 실리콘 수지를 이용할 있다. 가령, 상업화된 다우코팅사의 US-CF 2403 제품을 이용할 수 있다. The coating layer 19 can be formed by applying a coating agent to the surface of the pattern layer 18 once or two to three times. As a coating agent, transparent silicone resin can be used to improve physical performance and provide room temperature curing and high heat resistance. For example, Dow Coating's commercial US-CF 2403 product can be used.

상술한 바와 같이 합지층(16), 백색도장층(17), 패턴층(18), 코팅층(19)이 순차적으로 적층되면 한지시트(15)가 만들어진다. 이러한 한지시트(15)는 강도가 높고 내구성이 우수하다. 또한, 한지시트(15)는 투습방수성을 갖는다. As described above, when the laminate layer 16, the white painting layer 17, the pattern layer 18, and the coating layer 19 are sequentially stacked, the Korean paper sheet 15 is created. This Korean paper sheet 15 has high strength and excellent durability. In addition, the Korean paper sheet 15 has moisture-permeable and waterproof properties.

한지시트(15)는 접착제로 보드(11)의 상부에 부착시킨다. 접착제로 식물성인 송진 접착제를 이용할 수 있다. The Korean paper sheet 15 is attached to the top of the board 11 with adhesive. Vegetable rosin adhesive can be used as an adhesive.

보드(11)의 상부에 한지시트(15)를 부착한 본 발명의 마감재(10)는 마루 또는 장판과 같은 건물 바닥의 마감재로 사용된다. 또한, 본 발명의 마감재는 건물 벽면의 마감재로 사용될 수 있음은 물론이다. The finishing material 10 of the present invention, which has a Korean paper sheet 15 attached to the top of the board 11, is used as a finishing material for building floors such as flooring or flooring. In addition, of course, the finishing material of the present invention can be used as a finishing material for building walls.

이러한 본 발명의 마감재는 내구성이 우수할 뿐만 아니라 단열성, 흡음성, 방수성을 높인다. 또한, 친환경적인 소재가 사용되므로 인체 및 내부환경에 유익함과 동시에 표면에 선명한 칼라 패턴을 형성할 수 있어서 미려한 외관을 갖는다. The finishing material of the present invention not only has excellent durability, but also improves insulation, sound absorption, and waterproofing. In addition, since eco-friendly materials are used, it is beneficial to the human body and the internal environment, and at the same time, it has a beautiful appearance by forming a clear color pattern on the surface.

한편, 본 발명은 다른 예로 입상의 다공체가 첨가된 코팅제를 패턴층에 상부에 도포하여 코팅층을 형성시킬 수 있다. Meanwhile, in the present invention, as another example, a coating layer can be formed by applying a coating agent to which granular porous bodies are added onto the pattern layer.

다공체는 표면과 내부에 많은 기공이 형성된 구조를 갖는다. 다공체의 소재로 펄라이트, 제올라이트, 실리카 등을 들 수 있다. 다공체는 평균 입경이 0.01 내지 1mm인 입상으로 이루어진다. A porous material has a structure in which many pores are formed on the surface and inside. Porous materials include pearlite, zeolite, and silica. The porous body consists of particles with an average particle diameter of 0.01 to 1 mm.

바람직하게 다공체에는 별꽃아재비 추출액이 함침된다. 별꽃아재비 추출액은 우수한 항균활성을 갖는다. 따라서 별꽃아재비 추출액은 다공체의 기공에 함침되어 서서히 외부로 방출되면서 장기간 항균성을 부여할 수 있다. Preferably, the porous body is impregnated with chickweed extract. Chickweed extract has excellent antibacterial activity. Therefore, the chickweed extract can be impregnated into the pores of the porous body and slowly released to the outside, providing long-term antibacterial properties.

별꽃아재비(Galinsoga parviflora)는 국화과의 1년생 초본으로서, 잎 또는 전초를 이용한다. Galinsoga parviflora is an annual herb of the Asteraceae family, and its leaves or whole plants are used.

별꽃아재비 추출액은 송장풀의 전초에 추출용매를 가해 추출할 수 있다. 추출용매로 물, 탄소수 1 내지 4의 저급 알코올, 다가 알코올 또는 이들의 혼합물로부터 선택된 적어도 어느 하나를 이용할 수 있다. 탄소수 1 내지 4의 저급 알코올로 메탄올, 에탄올 등을 이용할 수 있고, 다가 알코올로 부틸렌글리콜 및 프로필렌글리콜, 펜틸렌글리콜 등을 이용할 수 있다. 그리고 혼합물로는 물 및 저급 알코올의 혼합물, 물 및 다가 알코올의 혼합물, 저급 알코올 및 다가 알코올의 혼합물, 또는 물 및 저급알코올 및 다가 알코올의 혼합물을 이용할 수 있다.Chickweed extract can be extracted by adding an extraction solvent to the root of the pine plant. As an extraction solvent, at least one selected from water, lower alcohols having 1 to 4 carbon atoms, polyhydric alcohols, or mixtures thereof can be used. Methanol, ethanol, etc. can be used as lower alcohols having 1 to 4 carbon atoms, and butylene glycol, propylene glycol, pentylene glycol, etc. can be used as polyhydric alcohols. The mixture may be a mixture of water and a lower alcohol, a mixture of water and a polyhydric alcohol, a mixture of a lower alcohol and a polyhydric alcohol, or a mixture of water, a lower alcohol, and a polyhydric alcohol.

추출의 일 예로 별꽃아재비의 전초에 대하여 추출용매를 중량비로 2 내지 20배를 가한 후 10 내지 120℃에서 1 내지 48시간 동안 열수추출, 냉침추출 또는 온침추출의 방법으로 추출할 수 있다. As an example of extraction, 2 to 20 times the weight ratio of the extraction solvent can be added to the whole plant of Chrysanthemum chickweed and then extracted by hot water extraction, cold needle extraction, or hot needle extraction at 10 to 120°C for 1 to 48 hours.

추출한 별꽃아재비 추출액에 다공체를 침지시켜 별꽃아재비 추출액을 다공체에 함침시킬 수 있다. 별꽃아재비 추출액을 함침시킨 다공체는 코팅제 100중량부에 대하여 2 내지 10중량부를 첨가할 수 있다. The porous body can be immersed in the extracted chickweed extract and the porous body can be impregnated with the chickweed extract. To the porous body impregnated with chickweed extract, 2 to 10 parts by weight can be added based on 100 parts by weight of coating agent.

별꽃아재비 전초에 물을 중량비로 8배를 가한 후 90℃에서 6시간 동안 추출하여 수득한 별꽃아재비 추출액을 시료로 하여 황색포도상구균(Staphylococcus aureus), 대장균(E. coli)을 대상으로 항균실험을 한 결과, 24시간 후 초기균수에 대한 감소율(%)이 각각 82.5%, 86.2%로 나타나 별꽃아재비 추출액의 항균활성이 확인되었다. An antibacterial test was conducted on Staphylococcus aureus and E. coli using the Chrysanthemum aureus extract obtained by adding 8 times the weight of water to the starch plant and extracting it at 90°C for 6 hours. As a result, the reduction rate (%) in the initial bacterial count after 24 hours was 82.5% and 86.2%, respectively, confirming the antibacterial activity of the chickweed extract.

이와 같이 본 발명은 별꽃아재비 추출액이 함침된 다공체를 첨가한 코팅제를 이용하여 코팅층을 형성할 경우 마감재의 기능성을 더욱 높일 수 있을 것으로 보인다. In this way, the present invention appears to be able to further increase the functionality of the finishing material when the coating layer is formed using a coating agent added to the porous body impregnated with chickweed extract.

이상, 본 발명은 일 실시 예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 실시 예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 보호 범위는 첨부된 청구범위에 의해서만 정해져야 할 것이다.Above, the present invention has been described with reference to one embodiment, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom.
