Embodiment 1

[0035] Such as figure 1 Shown: a thermosetting IMD film, including: PET base film 1, anti-scratch coating layer 2, film layer 3, and ink adhesion layer 4. An anti-scratch coating layer 2 is arranged on the upper surface 11 of the PET base film 1, a film layer 3 is arranged on the anti-scratch coating layer 2, and an ink adhesion layer 4 is arranged on the lower surface 12 of the PET base film. A film layer 3 is arranged on the layer 4 . The material of the film layer 3 is PE. The coating layer 2 is two layers. The first layer is a primer coupling layer 21 , and the second layer is a slide extrusion anti-scratch coating layer 22 . The primer coupling layer 21 is one layer. The thickness of the underlying coupling layer 21 can be selected to be 1-2 um, and in this embodiment, the thickness of the underlying coupling layer 21 is selected to be 1 um. The slide extrusion scratch-resistant coating layer 22 is one layer. The thickness of the slide extrusion anti-scratch coating...

Abstract

The invention provides a thermosetting type IMD film and a preparation method thereof. The IMD film comprises a PET (polyester) base film, wherein an anti-scraping coating layer is arranged on the upper surface of the PET base film; a film layer is arranged on the anti-scraping coating layer; an ink adhesion layer is arranged on the lower surface of the PET base film; the film layer is arranged on the ink adhesion layer; and the anti-scraping coating layer is a thermosetting coating layer. The preparation method comprises the following steps of performing corona on the PET base film; coating the PET base film; drying the coated PET base film; drying and curing the dried PET base film; coating the ink adhesion layer on the back of the thermoset PET base film; and drying and curing the PET base film of which the back is coated with the ink adhesion layer, coating the film on the two surfaces, and curing, rolling and cutting the film. The thermosetting type IMD film has the characteristics of high transmittance, flexibility and adhesion. The process of strengthening the coating is a progressive temperature raising process, the cross-linking of the coating is fuller, and the requirements of high transmittance, flexibility and adhesion are met.

Description

technical field [0001] The invention relates to the technical field of interior decoration films, in particular to a thermosetting IMD film and a preparation method thereof. Background technique [0002] As we all know, the surface of plastic products is not resistant to abrasion. In response to this feature, in recent years, a new injection molding process for interior decorative films has emerged, that is, in-mold injection molding technology. Specifically, the surface of a PET film is first coated with a scratch-resistant strengthening coating, and the other side is coated with an ink-absorbing layer. When processing plastic products, first print the required colors, patterns, trademarks, etc. on the inner layer. Then heat-setting according to the structure of the product, and then put it into the injection molding machine for injection molding, so that the inner decorative film and the plastic are integrated. And because some plastic parts need windows (such as panels...
