Abstract

The invention discloses a heat transfer printing foaming ink, a preparation method thereof and application of the heat transfer printing foaming ink in plastic products. The raw materials include thefollowing substances in parts by weight: 10-20 parts of low molecular alcohol, 5-10 parts of organosilicon microspheres, 10-20 parts of acrylic resin, 2-4 parts of XL-70, 0.2-0.5 part of a thickener,0.1-0.2 part of a defoamer, 8-10 parts of pigment and 30-50 parts of water. The organosilicon microsphere foaming ink of the invention effectively improves the performance of the final product throughself-made organosilicon microspheres, has good adhesion fastness, bright color, clear lines, and wide foaming multiple range, uses water as a solvent, is green and environmentally friendly, has simple preparation process and low cost, and is especially suitable for printing on the surface of plastic products.

Description

technical field [0001] The invention relates to the field of microsphere foaming inks, in particular to organosilicon microsphere foaming inks. Background technique [0002] Foaming ink means that after the printed ink is heated and cured, it will initiate a dot matrix of bubbles, making the patterns and imprints raised, and has a certain height of ink. There are two kinds of foaming inks: one is microsphere foaming ink, and the other is groove bottom foaming ink. [0003] Microsphere foaming ink is made by using the unique properties of microspheres, dispersing them into special polymer binders, and adding some other raw materials. This kind of ink is printed on paper, textiles and other substrates by screen printing. After low-temperature drying and heating in an oven to 120-140°C, the microspheres in the ink will expand to form countless tiny pores after a few seconds, so that Graphics present a three-dimensional effect. [0004] Microsphere foam inks are widely used i...
