Description
본 발명은 건축 및 일반 산업용으로 사용되는 보온 단열재의 페이싱지 (facing 紙)에 관한 것으로서, 특히 매트(mat)나 보오드(board) 또는 파이프 커버용으로 사용되는 페이싱지에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to facing paper for thermal insulation used in construction and general industries, and more particularly to facing paper used for mats, boards or pipe covers.
도 5에 나타낸 바와 같이 종래에는 건축 및 산업용으로 사용되는 보온 단열재의 페이싱지를 제조함에 있어서, 알루미늄호일(26)에 유리실(glass yarn)(28)과 크라프트지(kraft paper)등의 종이류(22)와 폴리에틸렌 계열(20)을 순차적으로 적층하여 페이싱지(1)를 형성하고, 도 6에 도시된 페이싱지 접착 설비에 의해 유리 섬유(glass wool)(2)등 같은 보온 단열재와 열 접착시킨다.As shown in Fig. 5, conventionally, in the manufacture of facing paper for thermal insulation materials used for building and industrial purposes, paper 22, such as glass yarn 28 and kraft paper, is made of aluminum foil 26. ) And the polyethylene series 20 are sequentially laminated to form a facing paper 1, and thermally bonded with a thermal insulating material such as glass wool 2 by means of the facing paper bonding facility shown in FIG. 6.
이와 같은 종래의 페이싱지는 사용중 페이싱지 표면의 알루미늄층의 부식과 습기의 침투를 예방할 수 없고 불에 대해 매우 취약하였다. 또한 유리실을 사용하고 있는데 이것은 제조설비가 특수하여 생산성이 극히 저조하고 제조시에 손실율이 커서 원가 손실을 유발하는 요인이 되어왔다. 또한 고온에 의해 서로 다른 박막을 상호 열 접착시키는 과정에서 박막별 열전달 차이에 의해 페이싱지 표면에 열수축에 의한 주름이 발생하여 외관 상태가 불량해지고, 충분한 강도를 가지지 못하는 단점이 있어왔다. 또한 습식접착방식(wet lamination)을 사용함으로써 생산성이 저조한 문제가 있어왔다.Such conventional facing paper was unable to prevent corrosion and moisture penetration of the aluminum layer on the surface of the facing paper during use and was very vulnerable to fire. In addition, glass chambers are used, which has been a special factor in manufacturing equipment, which has been extremely low in productivity and has a high loss rate during manufacturing, causing cost loss. In addition, in the process of thermally bonding different thin films to each other by high temperature, wrinkles due to heat shrinkage are generated on the surface of the facing paper due to differences in heat transfer for each thin film, resulting in poor appearance and poor strength. In addition, there has been a problem of low productivity due to the use of wet lamination.
이러한 종래 기술의 문제점을 해결하기 위한 기술수단이 제안되었는 바, 미국특허 제4310587호에서는, 화염에 대한 취약성과 습기침투를 방지할 목적으로 알루미늄박막층에 유기수지물이 도포된 비닐 보호층이 제시되고 있으며, 미국특허 제 4700521호에서는 금속제 박막층의 산화를 방지하기 위하여 플라스틱제 필름층이 금속제 박막층에 접합되어 있음을 명시하고 있다. 또한 영국특허 제 2011836호에서는 알루미늄박막층의 산화 방지를 위하여 광택제 혹은 이와 유사한 것으로 코팅된 것을 권리로 주장하고 있다. 한편 실용신안공보 공고번호 96-5147 제 2348호에서 제안되고 있는 단열재 커버지는 유리실을 제거하고 종이류의 이면에 염화고무계열의 난연제를 코팅처리하고 상기 종이류의 표면에 우레탄 계열 또는 폴리에틸렌 계열의 부식방지접착제를 도포한 후 그 위에 알루미늄증착층을 형성하고, 최종적으로 알루미늄증착층위에 공지의 필름류를 접착시켜서 구성되는 것을 특징으로 하고 있다. 상기와 같은 구조의 커버지를 통하여 알루미늄층의 부식을 억제하고, 최외면의 필름류을 통하여 습기의 침투를 예방하며, 종이류이면에 염화고무계열의 난연제로 코팅처리 되기 때문에 고열로부터의 커버지의 소손변형을 막아 내화성을 제고시킨다. 아울러 유리실로 기한 생산성저하 및 제조시 손실문제를 해결하고 있다. 그러나 상기 제안된 종래 기술에서는 고온에 의한 열접착방식에 의해 발생하는 필름의 열수축에의한 주름의 발생문제와 페이싱지의 강도부족문제는 해결 되고 있지 않다.Technical means for solving the problems of the prior art has been proposed, US Patent No. 4310587, a plastic protective layer coated with an organic resin on the aluminum thin film layer for the purpose of preventing fragility and moisture penetration into the flame is proposed. , US Patent No. 4700521 specifies that the plastic film layer is bonded to the metal thin film layer in order to prevent oxidation of the metal thin film layer. British Patent No. 2011836 also claims to be coated with a varnish or the like to prevent oxidation of the aluminum thin film layer. On the other hand, the insulation cover proposed in Korean Utility Model Publication No. 96-5147 No. 2348 removes the glass chamber, coated the flame retardant of chlorinated rubber series on the back side of paper, and prevents the corrosion of urethane or polyethylene series on the surface of the paper. After apply | coating an adhesive agent, an aluminum vapor deposition layer is formed on it, and finally it is characterized by consisting of adhering well-known films on an aluminum vapor deposition layer. It prevents the corrosion of the aluminum layer through the cover of the structure as described above, prevents the penetration of moisture through the film on the outermost surface, and prevents burnout deformation of the cover from the high temperature because the paper is coated with a flame retardant of chlorinated rubber series. Improve fire resistance. In addition, productivity problems due to glass chambers are being solved. However, the proposed prior art has not solved the problem of wrinkles caused by thermal contraction of the film and the lack of strength of the facing paper caused by the thermal bonding method due to the high temperature.
본 발명은 고온에의한 열접착방식 대신 저온에 의한 열접착방식을 사용가능케 하여 열 수축에 의한 표면의 주름발생문제를 제거하고, 종이류 대신 고밀도 폴리에틸렌(High Density Poly Ethylene ; HDPE 라고 함)계열의 필름을 사용함으로써 강도를 보강하고, 접착방식을 습식접착방식에서 건식접착방식(dry lamination) 또는 압출 접착방식(extrusion lamination)으로 변경함으로써 접착력 향상 및 생산성을 향상시킬 수 있고 아울러, 컷팅등의 작업성이 우수하고 외관의 상품성이 우수하여 상품의 고급화를 추구할 수 있는 페이싱지를 제공하는것을 그 목적으로 한다. 또한 본 발명의 다른 실시형태에 있어서는 고온의 파이프의 보온 단열재에 사용되는 페이싱지로서 기존의 것보다 매우 질기고 난연효과가 뛰어난 염화비닐필름을 접착하여 사용함으로써 고온의 파이프의 보온단열재에 보다 적합한 페이싱지를 제공하는 것을 그 목적으로 한다.The present invention eliminates the problem of wrinkles on the surface due to heat shrinkage by using a low temperature thermal bonding method instead of a high temperature thermal bonding method, and instead of paper, a high density polyethylene (HDPE) series By using a film, the strength is strengthened, and the adhesion method is changed from the wet bonding method to the dry lamination method or the extrusion lamination method, thereby improving adhesion and productivity, and also cutting workability. The purpose of the present invention is to provide a pacing paper which is excellent in appearance and excellent in merchandise so as to pursue high-quality products. In another embodiment of the present invention, a facing paper used for thermal insulation of a high temperature pipe is more suitable for thermal insulation of a high temperature pipe by bonding a vinyl chloride film which is very tough and flame retardant effect is superior to the conventional one. The purpose is to provide knowledge.
