Embodiment Construction

[0026] In order to better understand the present invention, the content of the present invention is further illustrated below in conjunction with the examples, but the content of the present invention is not limited to the following examples.

[0027] one. Production of Thermal Transfer Coated Films

[0028] 1. Corona treatment on one side of Dupont 25um BOPET film (carrier film) to a surface tension of 48 dynes or more;

[0029] 2. Dilute KP-1153 silicone resin (Shanghai Kaiping Resin Co., Ltd.) with butanone and toluene (the mass ratio of butanone and toluene is 1:1), and coat it on the surface of BOPET to form a uniform silicone resin coating , the coating amount is 4g per square meter; then, at 180°C, cure for 6 seconds;

[0030] The typical physical properties of silicone resin diluted with methyl ethyl ketone and toluene are shown in Table 1.

Abstract

The invention discloses a thermal transfer in-mould decoration and a preparation method thereof. As the thermal transfer in-mould decoration and the method adopt laser to grave metal gravure, and adopt a method for gravure printing and thermal transferring, a high-resolution effect (which is 600 dpi) of PET film sheet printing is realized, continuous patterns and gradient patterns can completely reappear, and the color with high transparence and high transmittance on the PET back surface can be realized. The color saturation is high, and the adhesion of a graphic ink layer and a PET film is firm. The in-mould decoration can bear the high-temperature impact, can extend while the PET film is extended in a 3D thermal forming process, and has high extension. The extended surface is completed, the ink layer cannot be broken and has no wrinkles. The thermal transfer in-mould decoration and the preparation method not only can realize the large-scale continuous production, but also can perfectly overcome the shortcoming that hot-melt resin of the ink coating layer cannot bear the high temperature impact during the molding process. Products obtained by using the method cannot flush ink and glue and has complete patterns. The patterns have the performances of high gloss, anti-friction, anti-scratch and weather resistance, so that the thermal transfer in-mould decoration and the preparation method can be permanently used with fidelity.

Description
