As a method of laminating kraft paper and shape paper, for example, In the "non-flammable panel and its manufacturing method" of Korean Patent Application No. 2004-0042892, "the first process (shape paper manufacturing process); melamine resin 40% by weight, urea resin 40% by weight, methyl ethyl alcohol 2% by weight, release agent 0.5 To prepare a melamine resin impregnation solution in a conventional manner by mixing the weight%, 0.5% by weight surfactant, 10% by weight water, 7% by weight methanol, and then impregnated with the melamine resin impregnation liquid (80g / ㎡) After impregnating the resin impregnation to 55 ± 5%, and dried at 110 ℃ to prepare a melamine resin paper, the second step (board manufacturing process): calcium carbonate 10g, silicon oxide 30g, pumice 30g, magnesium oxide 2g,5 g of magnesium chloride was added to the stirrer and stirred, 30 g of water was added to the mixture, and then mixed into a mold, and then the board was molded and cured for 20 hours, after which the non-flammable board was manufactured. Panel manufacturing process); After applying the adhesive on the upper part of the board manufactured in the second step, and laminated one sheet of melamine resin-shaped paper prepared in the first step on the upper part, and then 2000kg / at 120 ℃ to 150 ℃ After 2 hours of heat pressurization at a pressure of cm 2, cooling to room temperature over 24 hours, and then demolding to produce a non-combustible panel, the fourth step (processing step); After cutting according to the standard by using a cutting machine used), a groove is formed in the upper side and the side with a terona (a machine that cuts a part of the groove or the side), and protrusions are formed in the other side and the lower side, and then the non-combustible paint Machined with sprayer Discloses a method for producing a non-flammable panel characterized by coating powder.
그러나, 상기한 종래의 방법은 제3공정에서 나타난 바와 같이 필수적으로 접착제의 사용을 요하며 이에 의해 난연 테스트에 불리하고 유광제품의 경우 표면에 자국이 남아 광택이 저하할 뿐 아니라 접착제를 보다 균일하게 도포되도록 하기 위해 가압조건이 높은 온도에서 장시간 동안 수행하여야 하므로 작업공정이 복잡하다는 단점이 있다.However, the conventional method described above essentially requires the use of an adhesive, as shown in the third step, which is disadvantageous to flame retardant testing, and in the case of a glossy product, marks remain on the surface to reduce gloss and make the adhesive more uniform. In order to be applied, the pressurization condition has to be performed for a long time at a high temperature, so there is a disadvantage that the work process is complicated.

실험예.Experimental Example
상기 각 실시예 및 비교에에 따라 얻어진 모양지가 적층된 성형 마그네슘 보드를 적절한 사이즈로 재단하여 각층 간의 박리 현상의 발생 여부와 표면 상태를 육안으로 검사하여 그 결과를 다음 표 1에 나타냈다. 자세하게는 재단된 말단 부분을 손으로 까보았을 때 쉽게 박리되면 접착 불량으로, 그렇지 않으면 접착 양호로 나타냈으며, 표면 상태는 육안으로 관찰하였을 때 표면에 평탄화 정도와 광택의 상태를 평가하였다.The molded magnesium board on which the pattern paper obtained according to each of the above examples and the comparison was laminated was cut to an appropriate size to visually inspect the occurrence and the surface state of the peeling phenomenon between the layers, and the results are shown in Table 1 below. In detail, when the peeled terminal part was easily peeled by hand, it was shown to be poor in adhesion and otherwise in good adhesion, and the surface state was evaluated by the degree of flatness and gloss on the surface when visually observed.
상기와 같이 구성되는 본 발명의 모양지가 적층된 성형 마그네슘 보드의 제조방법은 접착제를 사용하지 않으면서도 각층 간의 박리가 발생하지 않는 단단한 접착력을 얻을 수 있고, 난연성이 우수하고 유광제품의 경우 표면에 자국을 전혀 남기지 않아 광택이 우수할 뿐 아니라 제조공정이 단순화되고 제조비용이 크게 줄어든 성형 마그네슘 제조 방법을 제공하는 유용한 발명이다.The method of manufacturing a molded magnesium board laminated with the pattern paper of the present invention configured as described above can obtain a firm adhesive force without peeling between layers without using an adhesive, and has excellent flame retardancy and marks on the surface of a glossy product. It is a useful invention that provides a method for producing molded magnesium, which leaves not at all excellent in gloss, but also simplifies the manufacturing process and greatly reduces the manufacturing cost.
