Problems solved by technology

In my country, the ink manufacturing industry basically produces traditional synthetic resin inks, which contain 35% to 40% of high-boiling petroleum solvents, so they contain more polycyclic aromatic hydrocarbons, and 3,4 of them are -Benzopyridine, 3-nitrobenzoketone, etc. also contain carcinogenic components, which have a large amount of residue on printed matter and last for a long time, which will endanger the health of users and are also an important source of pollution in the ink production process

Embodiment 1

[0015] Put 20% water, 25% vegetable oil, 15% ethanolamine, 0.5% organic silicon defoamer and 1% soybean lecithin wetting agent into a dispersion cylinder, and disperse evenly at 500r / min for 2 Hours, after the dispersion is even, the liquid is filtered, and the filtered emulsion is put into the dispersion tank again, and 25% water-soluble acrylic resin, 10% water-based acrylic color paste and 3% rosin polyol ester are added successively, according to 600r / Min speed, disperse evenly for 4 hours, finally add 0.5 parts of silicone defoamer and filter, then you can get an ink with strong adhesion and stable performance.

Embodiment 2

[0017] Put 20% water, 25% vegetable oil, 15% ethanolamine, 0.5% organic silicon defoamer and 1% soybean lecithin wetting agent into a dispersing cylinder, and disperse evenly at a speed of 600r / min for 1 Hours, after the dispersion is even, the liquid is filtered, and the filtered emulsion is put into the dispersion tank again, and 25% water-soluble acrylic resin, 10% water-based acrylic color paste and 3% rosin polyol ester are added successively, according to 600r / Min speed, disperse evenly for 4 hours, finally add 0.5 parts of silicone defoamer and filter, then you can get an ink with strong adhesion and stable performance.

Embodiment 3

[0019] Put 20% water, 25% vegetable oil, 15% ethanolamine, 0.5% organic silicon defoamer and 1% soybean lecithin wetting agent into a dispersion cylinder, and disperse evenly at 500r / min for 2 hour, after the dispersion is uniform, the liquid is filtered, and the filtered emulsion is put into the dispersion tank again, and 25% of water-soluble acrylic resin, 10% of water-based acrylic color paste and 3% of rosin polyol ester are added successively, according to 800r / min speed, disperse evenly for 2 hours, and finally add 0.5 parts of silicone defoamer and filter to get an ink with strong adhesion and stable performance.

Abstract

The invention relates to a method for modifying printing ink by adding colophony polyol ester. Modified colophony polyol ester is added, so that the adhesive force of the printing ink is modified, and besides, colophony glyceride overcomes the defect of poor heat stability of colophony. The prepared printing ink not only is high in adhesion strength, but also is good in stability, and has a broad application prospect.

Description

technical field [0001] The invention relates to a modification method of a novel ink, in particular to a modification method of an environment-friendly ink, and belongs to the field of ink chemical industry. Background technique [0002] With the continuous development of the printing industry, the application of ink has become more and more extensive, and the output has continued to increase. In 2010, the production of my country's ink industry reached the highest level in history. The output totaled 589,900 tons, accounting for 14% of the world's total, surpassing Germany and Japan for the first time to rank second in the world. [0003] Ink is a viscous colloidal fluid that is uniformly mixed with pigments, linking materials and additives and repeatedly rolled. In my country, the ink manufacturing industry basically produces traditional synthetic resin inks, which contain 35% to 40% of high-boiling petroleum solvents, so they contain more polycyclic aromatic hydrocarbons,...
