Description

폴리스티렌압출 시트의 미장코팅 형성방법Plastering coating method of polystyrene extrusion sheet

본 발 명은 폴리스티렌압출시-트 표면에 안료가 혼합된 폴리스티렌 코팅재를 코팅하여 나무결무늬와 같은 미장무늬가 형성되는 코팅이 이루어저서 외관이 아름다운 시-트가 되게 한 것이다.The present invention is to coat a polystyrene coating material mixed with pigment on the polystyrene extrusion sheet surface to form a plastering pattern such as wood grain pattern to make a beautiful sheet.

종래의 폴리스티렌압출시-트는 표면에 각종무늬를 내기 위해 무늬가 인쇄된 코팅용 필름을 별도로 제조하고 이를 시트에 접착하여 미장시-트를 제조하였기 때문에 제조공정이 복잡하고 다단의 공정을 거처야하므로 생산가격이 고가로 되는 결점이 있었다.Since the conventional polystyrene extrusion sheet is manufactured by separately coating a coating film with a pattern printed on the surface to produce various patterns and by attaching it to a sheet to prepare a plastering sheet, the manufacturing process is complicated and requires a multi-step process. There was a flaw that the production price became expensive.

본 발명은 이러한 종래의 결점을 시정하기 위하여 개발한 것으로 코팅재속에 일정비율의 안료를 혼합하여 코팅재를 조성하고 이 코팅재를 이동하는 시-트에 낙하시켜 압착 코팅하므로서 나무결 모양과 같은 무늬가 코팅과 동시에 현출되게 한 것인데 이를 도면에 의거 상세히 설명하면 다음과 같다.The present invention was developed to correct these conventional drawbacks by mixing a certain proportion of pigments in the coating material to form a coating material and the coating-like pattern, such as wood grain texture by dropping on the sheet to move the coating material at the same time The present invention is described in detail with reference to the drawings as follows.

도 1에서 표현되어 있는 바와 같이 시트제조용 폴리스티렌 칩을 압출기(1가)에서 용해하여 원통형(1a)으로 압출하고 절개하여 시-트(1)상태로 인출로울러(9)(9a)로 인출하여 권취부(10)로 이송시키고 인출로울러와 권취부사이에 코팅장치(가)를 설치하여 코팅용 폴리스티렌압출기(2)의 압출부와 코팅다이스(3)사이에 안료공급통(4)을 부착하여 250℃로 용융된 코팅재에 3∼4중량%에 해당하는 안료를 혼합하여 안료가 혼합된 코팅재(5)를 만들고 이를 가이드로울러(8)(8a)에 안내되면서 이송되는 폴리스티렌시-트(1) 표면에 낙하시켜 코팅재가 응고되기전에 표면온도가 60∼70℃정도되는 냉각로울러(7)로 코팅재표면을 압착하여 시-트 표면에 접합시키므로서 나무결무늬와 같은 미장문양(51)이 형성되는 코팅을 형성하는 것이다.As shown in FIG. 1, the polystyrene chip for sheet manufacturing is melted in an extruder (1), extruded into a cylindrical shape (1a), cut, and taken out to a take-out roller (9) (9a) in a sheet (1) state. Transfer to the installation section 10 and install the coating device (A) between the take-out roller and the winding section to attach the pigment supply cylinder (4) between the extrusion section of the coating polystyrene extruder (2) and the coating die (3). The surface of the polystyrene sheet (1) which is transported while being guided to the guide roller (8) (8a) by mixing the pigment corresponding to 3 to 4% by weight to the coating material melted at ℃ ℃ mixed with the pigment (5) Before the coating material is solidified and the coating material is solidified, the surface of the coating material is pressed with a cooling roller (7) having a surface temperature of about 60 to 70 ° C. and bonded to the sheet surface to form a plastering pattern (51) such as wood grain pattern. To form.

이때 안료공급통 속에는 표현하고저 하는 색상에 맞도록 상호친화력을 가지는 안료와 첨가물을 적절한 비율로 혼합하여 투입하게 되고 안료공급부가 코팅재 압출부와 압출다이스사이에 장치되므로 용융상태로 압출되는 코팅재에 일정량을 혼합하여 압출다이스를 거처 시-트 표면에 낙하시키게 되고 용융액이 냉각되기 전에 냉각로울러에 의하여 압착이 되므로 시트에 낙하되는 속도와 시트의 이송속도 및 첨가제 및 압착로울러의 압착작용에 의하여 도 4에서와 같이 미장무늬를 나타내는 코팅층이 형성되게 된다.In this case, the pigment supply container is mixed with an appropriate ratio of pigments and additives having mutual affinity to match the color to be expressed, and a certain amount is applied to the coating material extruded in a molten state because the pigment supply part is installed between the coating material extrusion part and the extrusion die. 4, and the extrusion die is dropped to the sheet surface and compressed by the cooling roller before the melt is cooled, so that the dropping speed of the sheet and the feeding speed of the sheet and the compression action of the additive and the pressing roller are shown in FIG. As described above, a coating layer showing a plastering pattern is formed.

따라서 본 발명의 미장무늬는 코팅과 동시에 무늬가 형성되므로 종래보다 간편하게 가격이 저렴한 코팅무늬시-트를 만들 수 있고 이로인해 각종 포장용기는 물론이고 건축용 내장재와 같은 다목적 에 유효적절하게 활용을 할수 있는 효과가 있다.Therefore, the plastering pattern of the present invention is a pattern is formed at the same time as the coating can be easily made inexpensive coating pattern sheet than before, thereby making it possible to effectively use for various purposes such as various packaging containers as well as building interior materials It works.
