본발명을 첨부도면에 의해 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings as follows.

도 1은 본발명의 공정도이다.1 is a process diagram of the present invention.

본발명은 그을음이 나지 않는 다층 접합 제조 방법으로 제조하게 되면 그을음이나 탄 흔적없이 레이저 커팅을 할 수 있다.If the present invention is manufactured by a multi-layer bonding manufacturing method without soot, laser cutting can be performed without soot or burn marks.

본발명의 제조방법은 천연펄프칩이나 천연펄프를 물에 풀어 섬유질을 분리한 후 펠트인 모포위에 섬유질을 다층으로 뿌려준후 드라이 공정을 거쳐 종이판지로 제작한다The manufacturing method of the present invention separates fibers by dissolving natural pulp chips or natural pulp in water, then spraying the fibers in multiple layers on a felt-in blanket and then drying them to produce paperboard.

통상 뿌려서 다층을 만듬에 있어서, 2, 3개층이 적정하다. 드라이공정은 종이판지 수분95% 건조후 6~7%를 함유하게 건조하는 것으로, 건조온도는 140~180℃의 온도에서 3~6분 동안건조한다.Usually, in making a multi-layer by spraying, two or three layers are appropriate. The drying process is to dry the paperboard to contain 6-7% after drying 95% of the moisture, and the drying temperature is 140-180℃ for 3-6 minutes.

이렇게 완성된 종이판지를 전분이나 밀풀을 이용하여 층을 이루게 접합을 하게 된다.The finished paperboard is joined to form a layer using starch or wheat paste.

이때 접착력을 높이기 위해 최소한의 부재료가 첨가 될 수 있으나, 어디까지나 최소한으로 첨가해야 한다.At this time, a minimum amount of auxiliary material may be added to increase the adhesion, but it should be added to the minimum.

다층의 경우 전분이나 밀풀을 이용하여 2중으로 접합하여 접합이 용이하게 프레스등을 통하여 누르는 공정을 거치게 된다.In the case of multi-layers, they are double-bonded using starch or wheat paste, so that bonding is facilitated through a pressing process such as a press.

위와 같은 공정을 여러번 거치게 되면서 원하는 두께로 제작한다.It is manufactured to the desired thickness by going through the above process several times.

그러므로 그을음이나 탄 자국이 남지 않는 레이저 커팅을 위해 중요한 사항은 불순물이 들어가지 않은 순수한 펄프 섬유질로 종이 판지를 만드는 것이다.Therefore, for laser cutting without soot or burn marks, it is important to make paperboard from pure pulp fibers that do not contain impurities.

따라서 본발명의 제조방법에 의해 제조된 다층 접합종이보드는 레이저 커팅시 그을음이 나지 않거나 극히 미량으로 발생하기에 절단 면이 깨끗하며 작업이 위생적이라는 현저한 효과가 있다.Therefore, the multilayer laminated paper board manufactured by the manufacturing method of the present invention has a remarkable effect that the cut surface is clean and the operation is hygienic because there is no soot or is generated in a very small amount during laser cutting.
