이하에서는 보다 구체적으로 첨부도면을 참조하여 본 발명을 설명하다. 하기의 설명은 본 발명의 이해와 실시를 돕기 위한 것이지 본 발명을 이에 한정하는 것은 아니다. 당업자들은 하기의 특허 청구범위에 기재된 본 발명의 사상 내에서 다양한 변형 및 수정이 있을 수 있음을 이해할 것이다.Hereinafter, the present invention will be described more specifically with reference to the accompanying drawings. The following description is provided to assist the understanding and implementation of the present invention, but the present invention is not limited thereto. It will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention as set forth in the following claims.

먼저, 본 발명에서 사용하는 PC는 내충격, 투명성, 내열성 및 전기적 성질이 뛰어나며 플라스틱 소재 중 충격강도가 우수하여 광학부품, 방음설비 등 다양한 분야에서 사용되는 소재이다.First, the PC used in the present invention is excellent in impact resistance, transparency, heat resistance and electrical properties, and is excellent in impact strength among plastic materials and used in various fields such as optical parts and soundproofing facilities.

또한 PCTG는 텔레프탈레이트(PET)의 물성을 개선한 원료로 유해물질인 비스페놀A가 포함되어 있지 않으며 내화학성이 뛰어나 화학적 성분 반응에 강하며 투명도가 높고 내구성이 뛰어난 물질이고, 에코젠을 옥수수나 밀과 같은 곡물에서 추출한 원료인 바이오 모노머를 섞어서 만들기 때문에 친환경소재이며 내화학성 및 접착성, 투명성 및 고광택 등을 갖고 있다. 이러한 물질들을 PC판넬이나 판재에 적용한 예는 없는것으로 판단된다.PCTG is a raw material that improves the physical properties of terephthalate (PET). It does not contain a toxic substance, bisphenol A, has excellent chemical resistance, is resistant to chemical reaction, has high transparency and durability, and echogen is used in corn, It is an eco-friendly material and has chemical resistance, adhesiveness, transparency and high gloss because it is made by mixing bio-monomer which is raw material extracted from the same grain. These materials are not considered to be applied to PC panels or plate materials.

본 발명에서의 판재는 PC플라스틱인 모재판재의 적어도 일면, 바람직하게는 상·하면에 PCTG를 40~120마이크론코팅한 내화학성이 강화된 폴리카보네트판재를 제공하는데, 상기에서 PCTG의 코팅층이 40마이크론 이하가 되면 내화학성이 약해지고, 120마이크론 이상이 되면 비경제적이기 때문에 상기와 같은 두께로 코팅한다.The plate material according to the present invention is a polycarbonate plate having a chemical resistance enhanced by coating 40 to 120 microns of PCTG on at least one surface, preferably upper and lower surfaces of a base material plate of PC plastic, wherein the coating layer of PCTG is 40 When it is less than microns, the chemical resistance is weakened. When it is not less than 120 microns, it is not economical.

코팅방법은 통상의 양면 코팅을 할 수 있는 공압출기를 사용하면 된다.As the coating method, a co-extruder capable of performing normal double-side coating may be used.

상기의 공압출기는 통상의 방법이므로 그 구체적 설명은 생략한다.Since the above co-extruder is a usual method, a detailed description thereof will be omitted.

본 발명에서는 압출기의 코팅층 온도를 130~160℃로 함이 바람직한데, 압출온도가 너무 낮으면 재료가 경화되어 원하는 제품이 나오지 않고, 온도가 너무 높으면 재료가 너무 묽게 되어 흐느적거리는 현상이 발생하며 제품에 하자가 발생하기 때문이다.In the present invention, the temperature of the coating layer of the extruder is preferably 130 to 160 ° C. If the extrusion temperature is too low, the material is hardened and the desired product is not produced. If the temperature is too high, the material becomes too thin, Because of defects.

상기와 같이 제조된 PC판재(10)는 중앙부위의 PC플라스틱(100)의 적어도 일면에 U.V차단재가 포함된 PCTG 또는 에코젠 코팅층(200)이 있어서 U.V는 차단되며 PCTG 또는 에코젠이 갖고 있는 내화학성으로 인하여 PC판재(10)의 내화학성을 크게 향상시킬 수 있게 된다.The PC plate material 10 manufactured as described above has a PCTG or ecojacent coating layer 200 containing a UV blocking material on at least one surface of the PC plastic 100 at the central portion thereof so that the UV is blocked and the PCTG or eco- The chemical resistance of the PC plate member 10 can be greatly improved due to chemical properties.

본 발명에서는 또한 도 2에서와 같이 PC플라스틱(100)의 적어도 일측, 바람직하게는 양측에 PCTG코팅층(200)의 적어도 일측에 PE폼(300)을 점착시킬 수도 있는데, 상기 PE폼(300)은 코팅층(200)에 본딩제로 점착하여 접착하고 50~80℃의 온도에서 1m당 10초의 통과속도로 통과시켜 열풍건조 후 통상적인 방법으로 압연 하면 된다.2, the PE foam 300 may be adhered to at least one side of the PCTG coating layer 200 on at least one side, preferably both sides, of the PC plastic 100, It may be adhered to the coating layer 200 with a bonding agent and then passed through at a passing speed of 10 seconds per 1 m at a temperature of 50 to 80 ° C, followed by hot air drying and rolling by a conventional method.

상기에서 온도가 너무 낮으면 접착시간이 느려지고, 너무 높으면 접착전 경화되어 불량이 일어날 수 있으므로 상기와 같이 한다.If the temperature is too low, the bonding time is slow. If the temperature is too high, it may be cured before bonding to cause defects.

상기와 같이 PE폼(300)층이 접착되면 보온 및 단열효과를 볼 수 있고 수증기를 흡수할 수가 있어서 결로방지에도 효과적이어서 창고나 축사 등의 천정재 또는 벽체용으로 용이하게 사용할 수가 있게 된다.When the PE foam 300 layer is adhered as described above, the heat insulation effect and the heat insulation effect can be seen and the water vapor can be absorbed, so that it is effective to prevent condensation, so that it can be easily used for a ceiling material such as a warehouse or a house or a wall.

상기와 같은 판재는 그 용도에 따라 절곡하여 사용할 수 있다. The above-mentioned sheet material can be used by bending according to its use.
