Abstract

The invention relates to gloss oil for IMD (In-Mold Decoration) printing ink, IMD printing ink, an IMD film and a preparation method of the gloss oil. The gloss oil for IMD printing ink consists of the following components by weight percent: 25-30% of cyclohexanone, 15-20% of isophorone, 15-20% of trimethylbenzene, 15-20% of Shenzhen PuRuiSen polyester resin ES-300 and 25-30% of Shenzhen PuRuiSen polyester resin ES-410. The preparation method of the gloss oil comprises the following steps: adding the cyclohexanone, isophorone and trimethylbenzene in a blender, turning on the blender, adding the polyester resin ES-300 and the polyester resin ES-410 during stirring, and stirring uniformly. Compared with the prior art, the invention has the advantages that the IMD film printed with the IMD printing ink prepared from the gloss oil provided by the invention does not deform during high-temperature injection, and the adhesion of the printing ink is good; and the curing agent prepared from 70% of 1,6-diisocyanatohexane and 30% of toluene diisocyanate can ensure the yellowing resistance and enhance the hardness of the printing ink at the same time.

Description

technical field [0001] The invention belongs to the technical field of ink, and more specifically relates to a varnish for IMD ink, an IMD ink, an IMD film and a preparation method thereof. technical background [0002] The traditional surface decoration of plastic parts is to print different patterns on the surface of plastic parts after plastic injection molding, or to apply a layer of coating, and these patterns or coatings will wear off due to long-term friction during use. It disappears, loses luster, is not scratch-resistant, and is prone to scratches; at the same time, during the construction process, the ink or paint solvent volatilizes and causes environmental pollution. In order to meet people's new requirements for surface decoration and environmental protection, IMD technology has been produced. [0003] IMD (In-Mold Decoration) is a new technology that places a film in the injection mold to decorate the appearance of plastic parts. That is to print the pattern ...
