Flexible special extinction printing ink containing modified glass powder and preparation method of flexible special extinction printing ink

Abstract

The invention relates to special printing ink and particularly relates to flexible special extinction printing ink containing modified glass powder and a preparation method of the flexible special extinction printing ink. The flexible special extinction printing ink is prepared from the following raw materials in parts by weight: 20-30 parts of hydroxyl acrylic resin, 2-3 parts of lead-free glass powder, 30-38 parts of alkyd resin, 2-4 parts of vinyl n-butyl ether, 2-3 parts of amino silicon oil, 4-8 parts of ethylene glycol diglycidyl ether, 2-5 parts of cellulose sulfate, 1-3 parts of borax, 15-20 parts of a DBE solvent, 12-18 parts of ethyl acetate, 20-30 parts of environment-friendly pigment and 2-4 parts of auxiliaries. The flexible special extinction printing ink disclosed by the invention adopts the hydroxyl acrylic resin and the alkyd resin as connecting materials and adopts the environment-friendly low-toxicity solvent to greatly improve the environment friendliness of the printing ink; the lead-free glass powder containing borax molten and mixed in the raw materials is subjected to surface modification with amino silicon oil, and thus the dispersibility of the lead-free glass powder containing borax in a resin solution is improved, and the glass powder mixed with the borax is capable of effectively quickening the curing of the printing ink slurry. The printing ink coating obtained by the special printing ink disclosed by the invention is excellent in mechanical performance after being dried, unlikely to scrape off and soft in gloss. The printed object has a great aesthetic feeling.

Description

technical field [0001] The invention relates to a special printing ink, in particular to a flexible special matting ink containing modified glass powder and a preparation method thereof. Background technique [0002] Special printing ink is a kind of ink developed to adapt to different printing materials and to achieve different printing effects. There are many types of special inks, common ones include luminous ink, sterilization ink, anti-counterfeiting ink, magnetic ink, scented ink, conductive Ink and so on, at present, toluene, xylene and other volatile solvents with high hazards are mostly used in the formula of special ink, which poses a great safety hazard, and the performance of water-based ink using water as the main solvent is not exhausted. As desired, therefore, there is an urgent need to develop special printing inks with low toxicity and good performance. Contents of the invention [0003] The object of the present invention is to provide a flexible special...
