Abstract

The invention relates to environmentally-friendly plastic table printing black ink and a preparation method thereof. In the invention, the characteristic of modified polyamide resins capable of being dissolved in alcohol is fully utilized to prepare an alcohol-soluble polyamide resin solution, the obtained alcohol-soluble polyamide resin solution can effectively form affinity with nitrocellulose resins having a low-molecular-weight structure and has excellent intermiscibility and good leveling property during the printing process, thus high-solid-content ink is prepared. The obtained ink has the printing viscosity capable of being diluted to 12 seconds, is adaptable to printing at a machine speed more than 350 m / min, and improves production efficiency.

Description

technical field [0001] The invention relates to a printing ink and a preparation method thereof, in particular to an environmentally friendly surface printing plastic black ink and a preparation method of the surface printing black ink. Background technique [0002] Plastic surface printing black ink is applied to the packaging and printing of PE and OPP plastic substrates. After printing on the surface of PE and OPP plastic films, the surface of the ink film does not need to be compounded with a layer of plastic film after the film is formed. The ink film is completely exposed to the packaging. Therefore, the requirements for good adhesion, wear resistance, light fastness, frost resistance, temperature resistance and environmental protection of the product are even more important. The surface printing black ink currently on the market mainly uses benzene and ketones as solvents, and polyamide resin and nitrocellulose resin as ink binders. Surface printing plastic inks are ...
