Description

Sublimation Heat Transfer Paper for PCM Steel Plates {A sublimation heating-transfer sheet for a PCM steel plate}

The present invention relates to a sublimation heat transfer paper capable of printing various patterns on a PCM steel plate, and in particular, it is possible to have a sublimation heat transfer surface in a good state while performing a transfer process in a short time using little sublimation heat transfer. The present invention relates to a sublimation heat transfer paper for PCM steel sheets, which enables the transfer of three-dimensional surfaces, planes, and edge surfaces of PCM steel sheets more efficiently.

In general, transfer paper is a kind of thermal transfer film used to print a wood pattern or marble pattern on the surface of the underlying PCM steel plate, and is usually thermoelectric because the transfer paper is bonded to the surface of the PCM steel plate by thermal reaction. It is also called a limb.

That is, the transfer paper is divided into an outer sheet and a transfer layer attached to the sheet, and the sheet is detached after bonding the transfer layer to the PCM steel plate surface as an outer surface for transport and protection of the transfer paper. , The transfer layer is to be bonded to the surface of the PCM steel sheet to exhibit a pattern.

Therefore, by attaching the transfer paper to the object surface through the appropriate temperature and pressure it is possible to express the desired pattern on the object.

On the other hand, in the case of displaying the pattern color on the PCM steel plate surface using the transfer paper, because the transfer paper is bonded to the PCM steel plate surface through an adhesive, the PCM steel plate surface to show the pattern should be processed, PCM steel plate to which the transfer paper is bonded The surface is precisely processed and polished, and then the primer coating layer is transferred to the surface of the PCM steel sheet using a spray coating, reverse coating, roll coating method, etc. to form a primer coating layer for transfer. After drying the fryer coating layer, the transfer paper is contacted with the primer coating layer and compressed while applying a temperature of about 150-200 ° C. to attach the transfer paper to the surface of the PCM steel sheet.

However, when the transfer paper is attached to the PCM steel plate by using the above method, the process of polishing the PCM steel plate, applying the primer coating for the transfer, and drying the coating layer are complicated and time-consuming. When workability is remarkably inferior and the complicated shape of the PCM steel plate becomes three-dimensional, the transfer paper is difficult to adhere to the coating layer precisely, so that the shape of the pattern is deformed by shrinkage of the sheet. Since the attached transfer paper has a uniform thickness and is difficult to attach, there are various problems such as poor product quality of the processed surface.

The present invention has been devised to solve the above problems, and it is possible to have a sublimation heat transfer surface in a good state while performing the transfer process in a short time with little effort using sublimation heat transfer. It is an object of the present invention to provide a sublimation heat transfer paper for PCM steel sheets which can more efficiently transfer three-dimensional surfaces, flat surfaces, and edge surfaces.

The present invention for achieving the above object is a sheet that is attached to the sublimation heat transfer layer to protect the sublimation heat transfer layer, and the acrylic resin, polyethylene wax, surfactants, dichloropropane and the like are mixed on the sheet surface and fixed The release layer is applied to a thickness to facilitate the removal of the sheet after transfer, and the celluloid acrylic resin, the additive and the sublimation dye are applied to the release layer by applying a predetermined thickness to various patterns appear on the surface of the PCM steel sheet. It is a structure made of ink layers.

That is, the sublimation heat transfer paper is composed of a sheet and a sublimation heat transfer layer, and the sublimation heat transfer layer is composed of a release layer and a print layer, but the print layer is various food package designs, furniture wood patterns, architectural marble, textile designs, stationery designs. By printing a desired color with a gravure printing copper plate, such as flooring design, and the release layer is formed so that the sheet can be easily peeled off, the role of this release layer sublimation heat transfer during the sublimation heat transfer operation of the sublimation heat transfer layer It can be easily sublimated heat transfer into the surface of the PCM steel sheet to accept, and also has a peelability.

Therefore, the sublimation heat transfer paper is directly in contact with the surface and the back surface of the PCM steel sheet, so that the pattern can be printed through the heat and constant pressure, sublimation heat transfer is possible in a short time with little effort, thereby improving the workability of the operator and In addition, the productivity of color-printed steel sheet can be improved, and even if the surface of the PCM steel sheet is flat, three-dimensional, or edge, easy sublimation heat transfer is possible. It can improve the quality and produce environmentally friendly products that prevent environmental pollution by sublimation heat transfer directly on the surface of PCM steel sheet.
