Problems solved by technology

However, the problem with the ink currently used is that during the high-temperature injection molding process, the high-temperature resin fluid impacts the ink layer on the sheet under high pressure, and the ink layer is often washed away.
In addition, for high-stretch samples, the adhesion between the ink and the sheet is not enough to cause serious warping problems, the flexibility and temperature resistance of the ink are not enough, and the existing ink has a strong odor and high environmental load, which limits the IML Use and Promotion of Technology

Abstract

The invention discloses IML gloss oil and IML printing ink, a preparation method and an application thereof. The IML gloss oil is obtained by dissolving saturated polyester resin in an organic solvent. The IML printing ink comprises an A component and an isocyanate curing agent with a mass ratio of 10:0.9-2; the A component comprises the following components: 40-89% of the IML gloss oil, 8-55% of pigment, 0.5-2% of a wetting dispersant, 0.5-1% of a defoamer, 0.5-1% of a levelling agent, 0.5-2% of a thickening agent, and 0-1.5% of extinction powder. The IML printing ink does not contain harmful or toxic substances for human body, such as benzene, toluene, xylene, isophorone and the like, and has the advantages of low odor environment and low environmental load; the IML printing ink has good adhesion performance, high-temperature ink-sweeping resistance, and tensile property, is widely applicable to fields of panels of household appliances, display screens and control panels, 3C product buttons, housing, and large-scale casings, automotive upholstery, and the like.

Description

technical field [0001] The invention belongs to the technical field of screen printing inks, and in particular relates to an IML varnish and an IML ink as well as a preparation method and application thereof. Background technique [0002] The traditional surface decoration is to print different patterns on the surface of injection-molded plastic devices, and the thickness of these pattern layers on the surface of the product is only a few microns. is to touch the button) and disappear, and cannot maintain a long-term bright color without fading, resulting in an unsightly surface, and is not scratch-resistant, and is prone to scratches. Even if printed on transparent materials, these patterns will not transmit light. For materials with uneven surfaces, the patterns can only be printed by transfer, which makes mass production difficult. In order to meet the new needs of society for surface decoration, new surface Decoration technology, namely IML technology, came into being. ...
