Description

Blocking prevention sheet for thermal transfer paper {A prevention blocking sheet for a heating-transfer sheet}

The present invention relates to a thermal transfer paper capable of printing various patterns on an object. Especially, the thermal transfer paper can be stored in a good state for a long time even in a high temperature and high humidity place, and also in a high temperature and humid climate change working environment. The present invention relates to a non-blocking sheet for thermal transfer paper, which is capable of producing a better thermal transfer paper by preventing poor blocking of limbs.

In general, the thermal transfer paper forms a release layer on the inner surface of a polyethylen terephthalate (PET) sheet, and the top layer is coated and then cured for a long time in a closed curing chamber, and then the base layer is coated on the pattern printed surface, and the base layer It is manufactured by apply | coating an adhesive layer to this.

That is, the thermal transfer paper is divided into an outer PET sheet and a transfer layer attached to the PET sheet. In the case of the PET sheet, the transfer layer is heated at a high temperature as an outer surface for transferring and protecting the thermal transfer paper. By compressing, the thermal transfer paper can be separated from the bonded state of the object surface.

Therefore, the desired pattern can be expressed on the surface of the object by adhering the thermal transfer paper to the object surface at an appropriate temperature and pressure, which is a general hot stamping thermal transfer paper using thermal energy.

In addition, the thermal transfer paper as described above is formed with a base layer on the printing surface of the pattern so that the transfer pattern can be clearly displayed on the surface of the object, by applying an adhesive to the base layer the thermal transfer paper on the surface of the object through the adhesive Is compressed while heating at a high temperature to attach the thermal transfer layer to the surface of the object.

By the way, the thermal transfer paper is wound on a winding roller using a winding machine in the form of a product, and is genuinely packaged in a roll form. In the case of the wound thermal transfer paper, the thermal transfer paper is stored for a long time in a high temperature and high humidity or exposed to direct sunlight for a long time When a high temperature is received in a closed space, blocking (ie, thermal transfer papers) may be caused to stick to each other, resulting in a poor thermal transfer paper.

In addition, in the manufacturing of the thermal transfer paper, since the blocking phenomenon is frequently generated in a working environment having a high temperature and a humid climate change, there are various problems such as deterioration of productability and processability of the thermal transfer paper.

The present invention has been devised to solve the above problems, and it is possible to store the manufactured thermal transfer paper in a good state for a long time even in a high temperature and high humidity place, and also in the working environment of high temperature and wet climate change. It is an object of the present invention to provide a blocking sheet for thermal transfer paper, which is capable of producing a better thermal transfer paper by preventing poor blocking.

The present invention for achieving the above object is a PET sheet attached to the thermal transfer layer to protect the thermal transfer layer and to perform thermal transfer, and a siloxane polymer, a crosslinking agent, a catalyst, etc. on the back of the PET sheet. The slip layer is mixed with the solvent and applied to a predetermined thickness so that the thermal transfer paper wound in the form of a roll can be smoothly released from the winding roller, and acrylic resin, polyethylene wax, surfactant, dichloropropane, etc. on the inner surface of the PET sheet. Is mixed and applied to the release layer to facilitate separation of the PET sheet, and a curing agent such as acryl, polystyrene wax, urethane polyester, vinyl chloride sol to attach the printing layer of various patterns to the release layer And a transparent upper primer layer coated with a predetermined thickness by adding a catalyst or the like.

That is, the anti-blocking sheet for thermal transfer paper consists of a PET sheet, a back slip layer, an inner surface release layer, and a transparent upper primer layer, wherein the back slip layer is dried and cured at a high temperature after application in a corrugator, The inner release layer and the transparent upper primer layer are coated in a corgi and dried and cured at a high temperature to attach printed layers of various patterns, and also prevent blocking from occurring in the thermal transfer paper on which the adhesive layer is formed. It is.

Therefore, the thermal transfer paper wound by the anti-blocking sheet can be stored in a good state for a long time even in a high temperature and high humidity place, and prevents poor blocking of the thermal transfer paper even in a high temperature and humid climate change working environment, thereby providing a better thermal transfer paper. It is possible to manufacture and improve the productivity and workability by remarkably shortening the transfer process even in the environment such as high temperature and humid subtropical region, and good quality thermal transfer paper is transferred directly to the object's surface. It can improve the quality of the product by making it appear.
