본 발명은 화장판에 관한 것으로, 보다 상세하게는 메라민수지가 함침된 투 명지를 사용하여 화장판과 MDF, 또는 P, B를 일시에 적층하여 제조공정을 간단히 할 수 있도록 한 것이다.The present invention relates to a decorative plate, and more particularly, by using a transparent paper impregnated with a melamine resin to laminate a decorative plate and MDF, or P, B at a time to simplify the manufacturing process.

일반적으로 마루판이나 마감판, 또는 테이블용 상판 등으로 사용되는 마감재는 고압과 저압의 메라민 화장판으로 구성된다.In general, the finishing material used as a floor board or a finishing plate, or a table top plate is composed of a high pressure and low pressure melamine veneer.

이중 고압메라민화장판(일명 HPL이라 함)은 인쇄지를 메라민수지나 요소수지 또는 메라민수지와 요소수지가 6:4로 혼합된 수지에 그리고 크라프트지를 페놀수지에 함침건조시킨 다음 건조된 크라프트기재 여러 장을 적층하고 상단에 건조된 인쇄지를 적층시켜 고압프레스에 삽입한 후 열경화시킨 얇은 판으로 구성되는 화장판으로 라미네이트화된 화장판은 가구마감재나 건축내장재로 사용되어 지고 있는 것이다.The high-pressure melamine cosmetic plate (also called HPL) is made by drying impregnated paper with resin of melamine or urea resin or resin mixed with 6: 4 mixture of melamine resin and urea resin, and kraft paper with phenol resin, and then drying several kraft substrates. Laminate and laminated on the top of the dried printing paper is inserted into the high-pressure press and laminated with a decorative plate consisting of a thin plate heat-cured is used as furniture finishing materials or building interior materials.

이때 열경화에 사용되는 프레스는 다단프레스로 작업조건은 통상적으로 단위압력40㎏/㎝에서 100㎏/㎝로 성형온도를 120도-140도로 유지시간을 20-40분 정도로 성형을 하고 성형이 완료되면 냉각수를 사용하여 냉각한 다음 열경화된 제품을 해체하고 피착제에 접착을 용이하게 샌딩설비를 이용하여 제품의 후면을 샌딩처리한 다음 P. B 또는 MDF에 별도의 접착설비를 이용하여 접착제를 도포한 다음 고압메라민화장판을 올려놓고 냉압프레스를 이용하여 2시간 이상 저압으로 유지시킨 다음 상온에서 1일 이상 양생한 다음 제단 가공하는 것이다.At this time, the press used for thermosetting is a multi-stage press. The working conditions are generally 100 kg / cm to 40 kg / cm in unit pressure. After cooling with coolant, disassemble the thermoset product and sand the back side of the product by using sanding equipment for easy adhesion to the adherend. After coating, put the high-pressure melamine cosmetic plate and keep it at low pressure for 2 hours or more by using a cold press, and then cure at least 1 day at room temperature, and then process the altar process.

그러나 이와 같은 제품은 재단가공시 절단면이 매끄럽고 충격강도에 매우 강한 장점은 있으나 복잡한 가공 공정과정 때문에 가격이 매우 비싸고 접착시간이 오래 걸리는 결함이 있는 것이다.However, these products have the advantages of smooth cutting edge and very strong impact strength when cutting, but they are very expensive and have a long adhesion time due to the complicated machining process.

저압메라민 화장판(일명 LPL이라 함)은 인쇄지에 메라민수지를 함침 건조시킨 시이트를 가공한 다음 P. B또는 MDF 상단과 하단에 메라민 시트를 적층하여 저압프레스 열판 내부에 삽입하여 열경화시킨다.The low pressure melamine decorative plate (also called LPL) is processed by printing a sheet of impregnated and dried melamine resin on a printing paper, and then laminated with a melamine sheet on the top and bottom of P. B or MDF and inserted into the low pressure hot plate to be thermally cured.

이때 열경화된 제품은 별도의 냉압공정을 거치지 않고 해체하여 사용한다.At this time, the thermoset product is used after being disassembled without going through a separate cold press process.

가공되는 설비의 조건은 단위압력 15㎏/㎝에서 20㎏/㎝로 성형온도를 160도-180도로 유지시간을 20-40초 정도로 열경화시키는 것이다.The condition of the equipment to be processed is to heat-set the holding temperature of 20-40 seconds at a molding temperature of 160 degrees to 180 degrees at a unit pressure of 15 kg / cm to 20 kg / cm.

그러나 이 제품은 가공공정이 간단하고 제품가격이 저렴하며 P. B 또는 MDF에 접착이 성형공정에서 바로 이루어지기 때문에 접착 공정이 필요치 않은 장점은 있으나, 가공절단 단면이 매끄럽지 못하고 약한 충격에도 깨짐 현상이 발생되는 결함과 피막두께가 얇기 때문에 충격강도에 약한 결함이 있는 것이다.However, this product has the advantage that the process is simple, the product price is low, and the adhesion process is not necessary because the adhesion to P. B or MDF is done directly in the molding process. Since the defects and the thickness of the coating are thin, there is a weak defect in the impact strength.

본 발명은 상기 고압메라민화장판과 저압메라민화장판의 결함을 해결하는 화장판을 제조하는 방법을 제공하고자 개발한 것이다.The present invention has been developed to provide a method for manufacturing a decorative plate to solve the defects of the high-pressure Meramine cosmetic plate and the low-pressure Meramine cosmetic plate.

또한 본 발명은 제조된 화장판을 구입하여 제품을 제조하는 것이 아니라 메라민이 함침된 무색투명지 또는 무색지를 P. B나 MDF 양면에 사용하고 그중 일면 또는 양면에 메라민수지가 함침된 인쇄지와 페놀수지가 함침된 크라프트지를 함께 적층시킨 다음 열압프레스를 사용하여 접착 구성하도록 함으로서 종래의 결함을 해결하도록 한 것이다.
In addition, the present invention does not manufacture the product by purchasing the manufactured decorative plate, but instead of using a colorless transparent paper or colorless paper impregnated with melamine on both sides of P. B or MDF, one side or both sides of the printing paper and phenolic resin impregnated with The conventional defect is solved by laminating impregnated kraft paper together and then adhesively constructing using a hot press.

이하 본 발명을 첨부된 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 P. B나 MDF(10)와 페놀수지가 함침된 크라프트지(11)와 메라민수지(또는 요소수지나 메라민수지와 요소수지가 6:4로 혼합된 수지)가 함침된 인쇄지(12)를 적층시킬 때 메라민수지가 함침된 무색투명지 또는 무색지(13)를 P. B나 MDF(10)와 페놀수지가 함침된 크라프트지(11)사이와 P. B나 MDF(10)의 이면에 위치시켜 함께 접착 구성하여 P. B나 MDF(10)에 화장판을 구성하도록 한 것으로, 메라민수지가 함침된 무색투명지 또는 무색지(13)를 이면에 구성하는 것은 힘을 방지하기 위한 발란스 시트로서의 역활을 수행하게 되는 것이다.The present invention is a printing paper impregnated with P. B or MDF (10) and phenol resin impregnated kraft paper (11) and the melamine resin (or resin mixed with urea resin or melamine resin and urea resin 6: 4) 12) When laminating the colorless transparent or colorless paper (13) impregnated with the melamine resin between P.B or MDF (10) and the kraft paper (11) impregnated with phenol resin and the P.B or MDF (10) It is placed on the back side and bonded together to form a makeup plate on P. B or MDF 10. The colorless transparent paper or colorless paper 13 impregnated with the melamine resin on the back side is a balance for preventing force. It will serve as a sheet.

이때 P. B나 MDF(10)의 이면에도 도2와 같이 페놀수지가 함침된 크라프트지(11)와 메라민수지(또는 요소수지나 메라민수지와 요소수지가 6:4로 혼합된 수지)가 함침된 인쇄지(12)를 적층시킴으로서 양면에 화장판을 구성할 수도 있는 것이다.At this time, the back surface of P. B or MDF 10 is impregnated with kraft paper 11 impregnated with phenolic resin and a melamine resin (or a resin in which urea resin or melamine resin and urea resin are mixed with 6: 4) as shown in FIG. By laminating the printed paper 12, a decorative plate may be formed on both sides.

또한 도3과 같이 인쇄지(12)의 표면에 메라민수지가 함침된 무색투명지(20)를 적층 성형할 수도 있는 것이다.In addition, as shown in FIG. 3, the colorless transparent paper 20 impregnated with the melamine resin may be laminated on the surface of the printing paper 12.

이때 사용되는 설비는 저압메라민화장판을 가공할 때 사용되는 설비를 사용할 수 있으며 성형조건을 단위압력 18㎏/㎝에서 30㎏/㎝로 성형온도를 180도-220도로 유지시간을 25-60초 정도로 열경화시키는 것이다.The equipment used at this time can use the equipment used to process the low-pressure melamine cosmetic sheet, and the molding condition is from 18 kg / cm to 30 kg / cm in unit pressure. It is thermosetting enough.

특히 본 발명은 메라민수지가 함침된 무색투명지 또는 무색지(13)를 사용함으로서 크라프트지와 인쇄지가 P. B나 MDF(10)에 접착될 때 우수한 접착력을 가질 수 있는 것이다.In particular, the present invention is capable of having excellent adhesion when kraft paper and printing paper are adhered to P. B or MDF 10 by using a colorless transparent or colorless paper 13 impregnated with a melamine resin.

상기와 같이 제조되는 본 발명은 화장판을 별도로 제조하여 이를 접착제를 사용하여 P. B나 MDF와 접착 구성할 때에 비해 제조시간이 아주 적게 소요될 뿐만 아니라 고압메라민화장판의 장점과 저압메라민화장판의 장점을 가질 수 있는 효과가 있는 것이다.The present invention prepared as described above takes a very short manufacturing time compared to when constructing a cosmetic plate and adhesive composition with P. B or MDF using an adhesive, as well as the advantages of high-pressure melamine cosmetic plate and low-pressure melamine cosmetic plate There is an effect that can have advantages.
