Abstract

The invention discloses a transfer printing ink for polypropylene plastics, and a preparation method and application thereof. The transfer printing ink for polypropylene plastics is composed of the following components: 15-35% chlorinated polypropylene resin, 20-30% thermoplastic acrylic resin, 5-15% polyketone resin, 1-2% stuffing, 4-20% pigment, 5-10% auxiliaries, and 20-40% solvent. The transfer printing ink is high in drying speed and stable, high in color concentration and stable in colloid properties; the transfer printing ink has good effects if being applied to direct transfer printing on the surface of the polypropylene plastics without pre-treatment; besides, the transfer printing ink is good in continuous printability, free of wire drawing, convenient for cleaning, clear in printed patterns, good in third dimension and excellent in adhesion.

Description

technical field [0001] The invention relates to a transfer ink, in particular to a pad printing ink for polypropylene plastic and its preparation method and application. Background technique [0002] At present, it is not possible to directly pad-print on polypropylene plastic in China. The reason is that polypropylene has high stereoregularity, is easy to crystallize, and has low surface polarity. It uses general ink for pad printing, and its adhesion is extremely poor. Therefore, it is usually necessary to use complex acid mixed solution etching, surface corona or flame treatment, and plasma treatment before pad printing. These pretreatments require large-scale machinery and equipment, and the treatment methods are unsafe and pollute the environment. [0003] Therefore, the existing technology needs further development. Contents of the invention [0004] The object of the present invention is to provide a kind of connecting material is chlorinated polypropylene resin an...
