CN-224210802-U - Viscous thermal sublimation transfer paper

Abstract

The utility model discloses adhesive thermal sublimation transfer paper, which relates to the technical field of thermal sublimation transfer paper and comprises a base paper body, wherein an adhesive layer is adhered to the top of the base paper body, a base material layer is adhered to one side of the adhesive layer, which is far away from the base paper body, and an ink layer is adhered to one side of the base material layer, which is far away from the adhesive layer. The substrate layer maintains the paper stiffness while isolating the bond layer decomposition products from ink contamination. The grid structure of the adhesive layer reduces the high-temperature contact area, accommodates the decomposed gas, and has stable melting and solidifying process, thereby ensuring the structural integrity when the transfer paper is fixedly separated from the printing stock.

Description

Viscous thermal sublimation transfer paper Technical Field The utility model relates to the technical field of printing of Bluetooth circuit control boards, in particular to adhesive thermal sublimation transfer paper. Background The thermal sublimation transfer printing is a new technology that images and texts such as portrait, landscape, characters and the like are printed on thermal sublimation transfer printing ink-jet paper in a mirror image mode by using an ink-jet printer filled with thermal sublimation transfer printing ink, and then the thermal sublimation printing ink on the thermal sublimation paper is heated to about 200 ℃ by thermal transfer printing equipment, so that the thermal sublimation printing ink on the thermal sublimation paper sublimates and permeates into a printing stock, and color images on the paper are realistically transferred onto materials such as textiles, porcelain cups, porcelain discs, porcelain plates and metals. In the use of current thermal sublimation photographic paper, transfer paper is more level and smooth when thermal transfer, and the heat can not be crooked immediately under the press, and paper and cloth can paste the level. At the moment of lifting the hot pressing plate during thermal transfer printing, the paper is adsorbed on the upper pressing plate together with the fabric and then falls down. At this time, the high-temperature transfer paper drifts to the cloth to generate shift secondary transfer, and ghost images with light colors are formed. In order to avoid double image, the four corners of the transfer paper, which are not printed with patterns, are coated with a little clear water to be adhered with the fabric or the rising speed of the pressing plate is reduced, and the problems of reducing the working efficiency and affecting the transfer quality exist in the prior art. For this purpose, the prior Chinese patent (publication No. CN 206913968U) discloses a viscous thermal sublimation transfer paper, the thermal sublimation transfer paper is provided with a base paper, an adhesive layer, an ink layer and a transfer paper from bottom to top, a sucrose layer is coated below the adhesive layer, and a plurality of pores with regular hexagon shapes are formed in the sucrose layer. According to the utility model, when the hot pressing plate is lifted during thermal transfer printing, the sucrose layer is adhered to the fabric, the thermal sublimation transfer printing square paper cannot be adsorbed and then falls down to cause ghost, the phenomena of ghost, edge warping and the like are avoided, the thermal sublimation transfer printing quality is improved, and the thermal sublimation transfer printing device is reasonable in structure and low in production cost. Above-mentioned transfer paper in the in-process of using, utilize the sucrose layer that sets up to promote the bonding effect of transfer paper in the use, avoided transfer paper to appear dropping and lead to the printing to produce the ghost image or the condition of perk limit at the in-process of printing, but the sucrose layer receives the temperature influence comparatively showing at the in-process of using, and sucrose probably decomposes under high temperature, and remaining caramelization material probably adheres to the printing stock surface, forms the spot or influences surface feel. For this purpose, we have devised a viscous thermal sublimation transfer paper to solve the above-mentioned problems. Disclosure of utility model The utility model aims to provide a viscous thermal sublimation transfer paper, which solves the problems in the background technology.
