preparation example Construction

[0037] The embodiment of the present invention also provides a preparation method of IMR matte ink, which includes the following steps: first dissolve the resin with a solvent, then add additives, fillers, and matting materials for mixing treatment, and finally filter the mixed solution obtained from the mixing treatment .

[0038] The method for preparing IMR matte ink provided by the invention has the advantages of simple process, low cost and small occupied space, and the ink directly obtained by the method can achieve the matte effect of IMR printing surface.

[0039] The embodiment of the present invention also provides a method for using IMR matte ink, which includes the following steps: printing the matte ink on the surface of the sheet, and covering it with PE film after drying; then drying, plastic molding; assembling into a mold for injection molding; mold, remove the PE film.

[0040] Specifically, the drying process of the method for using the IMR matte ink is: ba...

Abstract

The invention belongs to the technical field of inks and particularly relates to IMR (in-mold decoration by roller) matte ink and preparation and application methods thereof; the IMR matte ink is characterized by being made from, by weight, 20-30% of resin, 0-1% of a filling material, 3-20% of a dulling material, 0.2-1% of an aid, and 48-76.8% of a solvent. The IMR matte ink may replace matte coating spraying process, IMR printed surface can be matted, the cost is low, the yield is high, VOCs (volatile organic compounds) emission is low, and the IMR matte ink preparation and application methods are simple and feasible and high in efficiency and use small space.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to an IMR matte ink and a preparation and use method thereof. Background technique [0002] IMD is extrusion surface decoration technology (also known as in-mold decoration technology), which is characterized by surface hardened transparent film, middle printing pattern layer, back injection molding layer, and ink middle. This technology makes the product resistant to friction, prevents the surface from being scratched, and can keep the color bright and not easy to fade for a long time. It is mainly used in surface decoration and functional panels of home appliances. IMD is further divided into IML (in-mold insert extrusion) and IMR (in-mold transfer printing). The surface of IML has PET or PC sheet, while the surface film of IMR products is removed, only ink; the biggest difference between these two processes is the product Whether there is a transparent protective film on...
