Abstract

본 발명은 아크릴 쟁반 등의 용기를 제조하는데 사용하는 무늬 아크릴 판재와 이를 양산할 수 있는 성형방법 및 성형장치에 관한 것으로서, 종래에는 금형에 무늬지를 깔고 그 위에 액상의 아크릴수지를 부어서 무늬 아크릴 판재를 성형하거나 제품을 직접 성형하였는바, 이는 무늬지가 말린 꽃이나 면직물 원단과 같이 신축성이 없는 것일 경우에는 액상의 아크릴수지가 경화될 때 기포발생이 심하여 불량률이 많았으며, 하나의 형틀에 의해서 무늬아크릴 판재를 낱개로 성형하는 것이므로 작업시간에 비해 생산성이 상당히 떨어지는 문제점이 있었다.The present invention relates to a patterned acrylic sheet used to manufacture a container such as an acrylic tray, and a molding method and a molding apparatus capable of mass-producing the same. In the related art, a patterned acrylic sheet is formed by placing a patterned paper on a mold and pouring a liquid acrylic resin thereon. Molded or molded directly to the product, which is the case that the pattern paper is not stretchy, such as dried flowers or cotton fabric fabric, when the acrylic resin of the liquid is hard foamed a lot of defect rate, the pattern acrylic plate by one mold Since the molding to a single, there was a problem that the productivity is significantly lower than the working time.

이에따라 본 발명은 투명한 아크릴판(10a) (10b) 사이에 접착제(11)와 무늬지(12)를 삽착한 상태에서 표, 이면에 PP 필름이나 셀로판 재질의 커버지(13)로 감싸 다수의 무늬아크릴 소재(10)를 준비한 후 이러한 무늬아크릴 소재들을 차례로 승강되면서 80∼90℃의 온도로 가열되는 다수의 히팅다이 위에 하나씩 올려놓고 유압실린더로 상기 히팅다이들을 한꺼번에 차례로 압압하면서 20∼40분동안 가열 압착하고, 그후 압착된 무늬아크릴 소재들을 내어 자연건조 시킨 다음 표, 이면을 덮고 있는 커버지의 불필요한 테두리를 트리밍하여 무늬아크릴 판재를 제공하는 것으로서, 이러한 본 발명은 신축성이 없는 무늬지의 경우에도 기포발생이 없고 상기 무늬지가 항시 아크릴층의 중앙에 위치하여 판재에 휨 발생이 없으므로 성형성과 생산성이 뛰어난 것이다.Accordingly, in the present invention, the adhesive 11 and the pattern paper 12 are inserted between the transparent acrylic plates 10a and 10b. After preparing the acrylic material 10, these pattern acrylic materials are sequentially elevated and placed one by one on a plurality of heating dies heated to a temperature of 80 to 90 ° C., and then heated for 20 to 40 minutes while pressing the heating dies one by one with a hydraulic cylinder. After pressing, and then dried out by pressing the patterned acrylic materials, and then trimming the unnecessary edges of the cover paper covering the table, the back surface to provide a patterned acrylic sheet material, the present invention is a bubble generation even in the case of a non-elastic pattern paper Since the patterned paper is always located in the center of the acrylic layer, there is no warpage in the plate, which is excellent in formability and productivity.
