Description
본 고안은 장식용 시트에 관한 것으로, 보다 상세하게는, 음이온을 방출하는 기능성 장식용 시트에 관한 것이다.The present invention relates to a decorative sheet, and more particularly, to a functional decorative sheet that releases anions.
일반적으로, 장식용 시트는 문짝이나 가구의 표면에 부착되어 외관을 보기 좋게 하는 것이다.Generally, decorative sheets are attached to the surface of a door or furniture to enhance the appearance.
최근에, 건강에 대한 관심이 증가하면서 장식용 시트로부터 건강에 유익한 성분이 방출되게 할 필요가 있다.In recent years, there has been a need for the release of beneficial ingredients from decorative sheets with increasing health concerns.
소정의 물질로부터 방출되는 유익한 성분으로는 여러 가지가 있는데, 그 중에서 음이온은 인체와 접촉하여 인체 내의 혈액 중 나트륨이나 칼슘의 이온화 양을 증가시켜서 산성의 혈액을 약 알칼리성으로 변화시킬 뿐만 아니라 세포를 활성화시켜 인체의 저항력을 증진시키고 또한 교감신경의 흥분을 억제하는 효능을 가지고있다. 그 외에, 음이온은 공기정화작용, 탈취작용, 항균작용 등의 효능을 가지고 있다.There are many beneficial ingredients released from certain substances, among which anions come into contact with the human body to increase the amount of sodium or calcium in the blood in the human body, which not only changes the acidic blood to slightly alkaline, but also activates the cells. It has the effect of improving the body's resistance and suppressing the excitability of the sympathetic nerve. In addition, the anion has the effect of air purification, deodorization, antibacterial action.
따라서, 음이온을 방출하는 장식용 시트에 대한 필요성이 있다.Thus, there is a need for decorative sheets that release negative ions.
따라서, 본 고안은 전술한 필요성을 충족시키고자 안출된 것으로서, 음이온 방출 물질을 함유한 음이온 방출층이 시트의 상면에 소정의 두께로 도포된 장식용 시트를 제공하는데 있다.Accordingly, the present invention has been made to meet the above-described need, and provides a decorative sheet in which an anion emitting layer containing an anion emitting material is applied to a top surface of a sheet to a predetermined thickness.
도 1은 본 고안에 따른 장식용 시트의 단면도,1 is a cross-sectional view of a decorative sheet according to the present invention,
도 2는 본 고안에 따른 장식용 시트를 제조하는 공정을 개략적으로 도시한 도면이다.2 is a view schematically showing a process for producing a decorative sheet according to the present invention.
본 고안은 상기 목적을 달성하기 위해, 폴리염화비닐 기층과, 상기 폴리염화비닐 기층의 상면에 전사된 무늬층과, 상기 무늬층의 상면에 폴리염화비닐 필름을 코팅하여 형성된 표면보호층으로 이루어진 장식용 시트에 있어서, 상기 표면보호층의 상면에는 음이온 방출 물질을 함유한 음이온 방출층이 10-20㎛의 두께로 도포 형성된 것을 특징으로 한다.The present invention is a decorative material comprising a polyvinyl chloride base layer, a pattern layer transferred to the upper surface of the polyvinyl chloride base layer, and a surface protective layer formed by coating a polyvinyl chloride film on the upper surface of the pattern layer. In the sheet, the upper surface of the surface protection layer is characterized in that the anion-emitting layer containing an anion-emitting material is formed to have a thickness of 10-20㎛.
이하, 본 고안에 따른 음이온 방출 장식용 시트에 대하여 도 1을 참조하여 설명하면 다음과 같다.Hereinafter, with reference to Figure 1 with respect to the anion-emitting decorative sheet according to the present invention.
도 1에 도시된 본 고안의 장식용 시트(1)는, 폴리염화비닐 기층(2)과, 폴리염화비닐 기층(2)의 상면에 전사된 무늬층(3)과, 무늬층(3)의 상면에 폴리염화비닐 필름을 코팅하여 형성된 표면보호층(4)으로 이루어져 있다. 특히, 본 고안의 장식용 시트(1)는 음이온을 방출하기 위해 표면보호층(4)의 상면에 음이온 방출 물질을 함유한 음이온 방출층(5)을 10-20㎛의 두께로 도포 형성한 것이다.The decorative sheet 1 of the present invention shown in FIG. 1 includes a polyvinyl chloride base layer 2, a pattern layer 3 transferred to an upper surface of the polyvinyl chloride base layer 2, and an upper surface of the pattern layer 3. It consists of a surface protective layer (4) formed by coating a polyvinyl chloride film. In particular, the decorative sheet 1 of the present invention is formed by applying an anion-releasing layer 5 containing an anion-releasing material on the upper surface of the surface protective layer 4 in a thickness of 10-20 μm in order to release anion.
여기에서, 음이온 방출 물질은, 자연상태에서 음이온을 다량 방출하는 물질로 알려진 ZrO2, Na2O, SiO2, Al2O3, P2O, K2O, MgO을 분말화한 것이다.Here, the anion-releasing material is a powder of ZrO 2 , Na 2 O, SiO 2 , Al 2 O 3 , P 2 O, K 2 O, and MgO, which are known as substances which release large amounts of anions in nature.
이하, 상면에 음이온 방출 물질을 함유한 음이온 방출층(5)이 형성된 본 고안의 장식용 시트(1)를 제조하는 방법에 대하여 설명한다.Hereinafter, a method of manufacturing the decorative sheet 1 of the present invention having an anion emitting layer 5 containing an anion emitting material on its upper surface will be described.
먼저, ZrO2분말 11.9-15.6중량%와, Na2O 분말 3.3-4.1중량%와, SiO2분말 65.4-72.9중량%와, Al2O3분말 4.6-5.8중량%와, P2O 분말 2.4-3.0중량%와, K2O 분말 1.1-1.3중량%와, MgO 분말 3.8-4.8중량%를 혼합한 음이온 방출 물질 분말 혼합물과 2액형 폴리우레탄 수지도료를 1.0-2.0:100의 중량비율로 혼합하여 용기(8)에 수용한다.First, 11.9-15.6% by weight of ZrO 2 powder, 3.3-4.1% by weight of Na 2 O powder, 65.4-72.9% by weight of SiO 2 powder, 4.6-5.8% by weight of Al 2 O 3 powder, P 2 O powder 2.4 Anion-releasing material powder mixture of -3.0% by weight, 1.1-1.3% by weight of K 2 O powder, and 3.8-4.8% by weight of MgO powder, and a two-component polyurethane resin were mixed in a weight ratio of 1.0-2.0: 100. In the container 8.
여기에서, 2액형 폴리우레탄 수지도료는 우레탄결합(-OCONH-)을 도막 중에 갖는 도료의 총칭이다. 따라서, 도막형성 요소중에 우레탄 결합을 함유치 않아도 도막형성 반응과정에서 우레탄결합이 만들어지는 도료도 폴리우레탄 수지 도료라 한다. 즉, 2액형 폴리우레탄 수지도료는 OH기를 다수 가진 폴리올 성분과 이소시아네이트기 (-NCO-)를 다수 가진 가교성분을 사용직전에 혼합하여 우레탄결합을 만들어 도막을 형성하는 것이다.Here, the two-component polyurethane resin is a generic term for a paint having a urethane bond (-OCONH-) in the coating film. Therefore, even when the urethane bond is not contained in the film forming element, the paint in which the urethane bond is made during the film forming reaction is also called a polyurethane resin paint. That is, the two-component polyurethane resin is a polyol component having a large number of OH groups and a crosslinking component having a large number of isocyanate groups (-NCO-) to form a coating film by mixing a urethane bond just before use.
시판되는 2액형 폴리우레탄 수지도료는 에폭시도료와 같이 각종 타입이 있으며 그 도막형성 기구도 다르다. 폴리우레탄 수지도료의 타입에 관계없이 공통되는 특징은 폴리올과 이소시아네이트의 우레탄 결합으로 인해 강인한 도막을 형성하므로 평활성 및 밀착력이 우수하다는 점이다. 시판되는 2액형 폴리우레탄 수지도료의예를 들면, 경기도 시흥시 정왕동 시화공단 1마 306호에 소재한 주식회사 경동실업에서 제조하여 판매하는 상품명 "KU 처리제" 등이 있다.Commercially available two-component polyurethane resins have various types, such as epoxy paints, and their coating film forming mechanisms are also different. Regardless of the type of polyurethane resin, a common feature is that the urethane bonds of polyol and isocyanate form a strong coating film, so that smoothness and adhesion are excellent. Examples of commercially available two-component polyurethane resins include the trade name " KU treatment agent " manufactured and sold by Kyungdong Industrial Co., Ltd., located at 1306, 306, Sihwa Industrial Complex, Jeongwang-dong, Siheung-si, Gyeonggi-do.
음이온 방출 물질 분말 혼합물과 2액형 폴리우레탄 수지도료의 혼합중량비율이 상기 범위를 벗어나면 문제가 있다. 즉, 2액형 폴리우레탄 수지도료의 중량 100에 대한 음이온 방출 물질 분말 혼합물의 중량이 1.0 이하이면, 음이온의 방출수가 너무 적어 음이온 방출 장식용 시트로서의 효능이 없으며, 또한, 2액형 폴리우레탄 수지도료의 중량 100에 대한 음이온 방출 물질 분말 혼합물의 중량이 2.0 이상이면, 투명성이 저하되어 무늬층(3)의 무늬가 잘 보이지 않게 되는 문제가 있다.There is a problem if the mixed weight ratio of the anion-releasing material powder mixture and the two-component polyurethane resin is outside the above range. That is, when the weight of the anion-releasing material powder mixture with respect to the weight 100 of the two-component polyurethane resin is less than 1.0, the number of anions is too small to be effective as an anion-releasing decorative sheet, and the weight of the two-component polyurethane resin is also If the weight of the anion-releasing material powder mixture with respect to 100 is 2.0 or more, there is a problem that the transparency is lowered and the pattern of the pattern layer 3 is hardly visible.
또한, 용기(8)에 수용된 혼합물은 메시롤(40)에 묻혀져 메시롤(40)과 러버롤(50) 사이에 끼여 진행하는 시트(1)의 상면에 도포된다. 이때, 혼합물은 메시롤(40)에 묻혀진 다음 닥터블레이드(60)로 긁어내어진다. 여기에서, 닥터블레이드(60)와 메시롤(40) 사이의 각도(θ)가 40-50°로 되게 함과 동시에 닥터블레이드(60)와 메시롤(40) 사이의 간격(t)이 0.01-0.03㎜로 되게 하여야 된다. 닥터블레이드(60)와 메시롤(40) 사이의 각도(θ)가 상기 범위를 벗어나면 닥터블레이드(60)에 의해 긁어진 메시롤(40)에 묻은 혼합물의 표면이 매끄럽게 되지 않게 된다. 또한, 닥터블레이드(60)와 메시롤(40) 사이의 간격(t)이 상기 범위를 벗어나면 표면보호층(4)의 상면에 도포되는 음이온 방출층(5)이 10-20㎛의 두께를 벗어나게 되는데, 음이온 방출층(5)의 두께가 20㎛ 이상이 되면 음이온이 그만큼 많이 방출되기는 하나 고가의 음이온 방출물질이 많이 들게 되므로 제조비용이 많이 들게 되고, 음이온 방출층(5)의 두께가 20㎛ 이하가 되면 음이온 방출량이 너무 적어 음이온의 효능이 잘 나타나지 않게 된다. 특히, 닥터블레이드(60)와 메시롤(40) 사이의 각도(θ)는 45°로 되게 하고, 닥터블레이드(60)와 메시롤(40) 사이의 간격(t)은 0.02㎜로 되게 하는 것이 보다 바람직하다.In addition, the mixture contained in the container 8 is buried in the mesh roll 40 and applied to the upper surface of the sheet 1 advancing between the mesh roll 40 and the rubber roll 50. At this time, the mixture is buried in the mesh roll 40 and scraped off with the doctor blade 60. Here, the angle θ between the doctor blade 60 and the mesh roll 40 is 40-50 ° and the interval t between the doctor blade 60 and the mesh roll 40 is 0.01-. It should be 0.03mm. When the angle θ between the doctor blade 60 and the mesh roll 40 is out of the above range, the surface of the mixture buried in the mesh roll 40 scratched by the doctor blade 60 is not smoothed. In addition, when the interval t between the doctor blade 60 and the mesh roll 40 is out of the above range, the anion emitting layer 5 applied to the upper surface of the surface protection layer 4 may have a thickness of 10-20 μm. If the thickness of the anion emitting layer (5) is 20㎛ or more, the anion is released as much, but the expensive anion emitting material is expensive because it takes a lot of manufacturing cost, the thickness of the anion emitting layer (5) 20 If the thickness is less than or equal to anion, the amount of anion released is so small that the effect of the anion is hardly shown. In particular, the angle θ between the doctor blade 60 and the mesh roll 40 is set to 45 °, and the distance t between the doctor blade 60 and the mesh roll 40 is set to 0.02 mm. More preferred.
또한, 메시롤(40)의 회전속도는 20-30m/mim 인 것이 바람직하다. 메시롤(40)의 회전속도가 20-30m/mim 를 벗어나면 용기(8) 내의 혼합물이 메시롤(40)에 제대로 묻혀지지 않거나 너무 많이 묻혀진다.In addition, the rotation speed of the mesh roll 40 is preferably 20-30 m / mim. If the rotational speed of the mesh roll 40 is out of 20-30 m / mim, the mixture in the container 8 may not be properly buried in the mesh roll 40 or may be buried too much.
이하, 본 고안에 따른 음이온 방출 장식용 시트의 일실시예에 대하여 설명한다.Hereinafter, an embodiment of the anion-emitting decorative sheet according to the present invention will be described.
먼저, ZrO2분말 14.2중량%와, Na2O 분말 3.7중량%와, SiO2분말 68.5중량%와, Al2O3분말 5.3중량%와, P2O 분말 2.7중량%와, K2O 분말 1.2중량%와, MgO 분말 4.4중량%를 혼합한 음이온 방출 물질 분말 혼합물과 2액형 폴리우레탄 수지도료를 1.5:100의 중량비율로 혼합하여 용기(8)에 수용한 다음, 상기 용기(8)에 수용된 혼합물을 장식용 시트(1)의 표면보호층(4)의 상면에 도포하여 음이온 방출층(5)을 15㎛의 두께로 형성한다. 이렇게 제조된 음이온 방출 장식용 시트의 음이온 방출수를 측정하기 위해, 본 출원인은 서울시 서초구 서초3동 1465-4에 소재한 한국건자재시험연구원에 상기 실시예로 제조된 음이온 방출 장식용 시트의 음이온 방출수를 측정 시험을 의뢰하였다. 한국건자재시험연구원에서는, 상기 실시예의 음이온 방출 장식용 시트를 내경이 44mm이고 높이가 297mm인 원기둥으로 만들어 시험편으로 하였으며, 전하입자 측정장치를 이용하여 온도 24℃, 습도 42%, 대기중 음이온수52/cc의 조건에서 상기 시험편에서 방출되는 음이온을를 측정하였다. 방출되는 음이온은 단위 체적당 이온수로 표시된다. 그 결과, 상기 시험편에서 방출되는 음이온수가 660/cc인 것으로 측정되었으며, 이는 단위면적당 음이온수가 우수한 것으로 인정된다.First, 14.2% by weight ZrO 2 powder, 3.7% by weight Na 2 O powder, 68.5% by weight SiO 2 powder, 5.3% by weight Al 2 O 3 powder, 2.7% by weight P 2 O powder, K 2 O powder An anion-releasing material powder mixture of 1.2% by weight, 4.4% by weight of MgO powder, and a two-component polyurethane resin were mixed in a weight ratio of 1.5: 100 and accommodated in the container 8, and then in the container 8 The received mixture is applied to the upper surface of the surface protective layer 4 of the decorative sheet 1 to form the anion emitting layer 5 to a thickness of 15 mu m. In order to measure the anion emission number of the anion emission decorative sheet thus prepared, the applicant measures the anion emission number of the anion emission decorative sheet manufactured in the above example at the Korea Building Materials Testing Institute located at 1465-4, Seocho 3-dong, Seocho-gu, Seoul. A test was requested. At the Korea Institute of Construction Materials and Materials, the anion-emitting decorative sheet of the above example was made into a cylinder having an inner diameter of 44 mm and a height of 297 mm to form a test piece. The anion released from the test piece under the conditions of cc was measured. The anions released are expressed in number of ions per unit volume. As a result, it was determined that the anion number released from the test piece was 660 / cc, which is considered to be excellent in the number of anions per unit area.
한편, 음이온 방출 물질들 중에서 SiO2, Al2O3는 음이온을 방출하는 것 외에 원적외선을 방출하기도 한다.On the other hand, among the anion emitting materials, SiO 2 and Al 2 O 3 may emit far infrared rays in addition to emitting anions.
전술한 본 고안의 음이온 방출 장식용 시트에 의하면, 시트의 표면에서 음이온이 다량 방출되므로 실내의 가구 등에 부착되는 경우 인체에 도움을 준다.According to the anion-emitting decorative sheet of the present invention described above, since a large amount of negative ions are released from the surface of the sheet, it helps the human body when attached to indoor furniture and the like.
