Problems solved by technology

The disadvantage is that the solvent volatilizes quickly and has a strong pungent smell. According to US Patent US 5371279, ethylene glycol butyl ether acetate decomposes in an environment with high water content or heavy humidity, and will produce acidic substances; The patent US 2009/0139432A1 pointed out that such acidic substances can easily cause corrosion of the nozzle, causing the nozzle to produce oblique spraying and hole breakage, which affects the quality of inkjet, and the acidic substance is suppressed by adding alcohol amine compounds; similarly, the European patent EP 2284226A1 also pointed out the problem of acid corrosion of ink, which changed to use cyclohexylamine and imidazole compounds as acid regulators, but the regulators such as alcohol amines and imidazoles all have high toxicity and corrosion, and are difficult to operate and use. ha

Embodiment Construction

[0020] For a further understanding of the present invention, please refer to the following examples. The following examples are only preferred examples of the present invention, and cannot be used to limit the scope of the claims of the present invention.

[0021] (Preparation of Nano Pigment Dispersion Liquid)

[0022] In 68 parts by weight of diethylene glycol diethyl ether, add 20 parts by weight of carbon black (Mitsubishi Chemical, MA-100R) and 12 parts by weight of dispersant (Evonik, Germany, TEGO Dispers-652), and stir the disperser at a high speed , the rotation speed was set at 500 rpm, and after stirring for 1 hour, 50% volume zirconium beads (2.0 mm) were added to the bead mill for pre-dispersion. The obtained coarsely ground pigment dispersion had an average particle diameter of 1 μm or less. The coarsely ground pigment dispersion was transported to a nano grinder for dispersion, and a black pigment dispersion was obtained through particle size analysis and filt...

Abstract

A low odor environment-friendly type nano pigment inkjet ink composition has excellent storage stability, inkjet stability and printing quality. A spray nozzle orifice is not easy to be blocked, printed images are high in gloss, resistant to scraping and resistant to weather. A low toxicity and low odor material is used. The ink has a high flash point and is safe for human health and environment, and meets the needs of environmental protection and maintaining print quality. The ink composition comprises 1-10% of N-ethyl pyrrolidone, 1-20% of propylene carbonate, 50-80% of ether alcohol solvents, pigments, a dispersant, resin, a plasticizer, a surface active agent and a cyclic tertiary amine compound as an acid adjusting agent.

Description

technical field [0001] The invention relates to an inkjet ink composition, in particular to a low-odor environment-friendly nano-pigment inkjet ink composition, which can be used in a solvent-type piezoelectric inkjet printer. The ink uses a low-odor, low-toxicity solvent , without adding any harmful substances, the ink has good storage stability and inkjet stability, the printed image has high gloss, scratch resistance and weather resistance, and more importantly, the ink is not easy to block the nozzle holes of the nozzle, and can have Requirements for environmental protection and maintaining print quality. Background technique [0002] Digital inkjet is controlled by software, using the nozzle to spray ink onto the printing medium to form text or images. This liquid inkjet method can be divided into thermal head and piezoelectric (Piezo head) according to the mechanism of the nozzle. , under the control of the piezoelectric technology, the piezoelectric element is deform...
