Problems solved by technology

[0005] Moreover, with the increase of social demand, the types and output of ink have also expanded and increased accordingly, but there are still some defects, such as poor adhesion, easy to be scratched, and poor use effect; Toluene is the main solvent, the residual solvent is large, and the benzene content exceeds the standard, which is easy to cause pollution in packaging and printing, especially not suitable for food packaging and printing

preparation example Construction

[0036] The present invention also provides the preparation method of above-mentioned printing ink, comprises the following steps:

[0037] A) mixing chlorinated polypropylene carbonate, rosin and / or rosin derivatives, acetone and part of the solvent, and dissolving to obtain the first mixed solution;

[0038] B) mixing and dissolving fillers, pigments, additives and the remaining solvent to obtain a second mixed solution;

[0039] C) mixing the first mixed liquid with the second mixed liquid to obtain ink.

[0040] Among the present invention, use chlorinated polypropylene carbonate, rosin and / or rosin derivative, acetone, solvent, filler, pigment and auxiliary agent as raw material to prepare printing ink, the type and consumption of raw material used are the same as the raw material type and amount in the above-mentioned ink. The dosage is the same, so I won’t repeat them one by one here.

[0041] In the present invention, chlorinated polypropylene carbonate, rosin and / or ...

Embodiment 1

[0050] Mix 45g chlorinated polypropylene carbonate, 9gDCH2102 rosin modified phenolic formaldehyde, 6g acetone and 12g ethyl acetate, use a disperser to disperse, adjust the rotating speed to 700 rpm, and disperse for 15 minutes to obtain the first mixed solution; Mix kaolin, 16g benzidine yellow, 0.4g polydimethylsiloxane, 3.6g diethyl phthalate and 5g ethyl acetate, disperse with a disperser, adjust the speed to 700 rpm, and disperse for 10 minutes , to obtain the second mixture. Add the second mixed solution to the first mixed solution, use a disperser to disperse, adjust the speed to 1200 rpm, disperse for 30 minutes, then put it into a sand mill for sand milling, adjust the feed pressure to 0.1MPa, and sand mill The temperature is 45° C., and the ink is sanded until the fineness reaches 6 μm.

[0051] The adhesion of the ink obtained in this embodiment was tested by the alcohol test method and the cross-knife test method. The test results showed that no ink fell off in t...

Embodiment 2

[0053] Mix 47g chlorinated polypropylene carbonate, 9gDCH2102 rosin modified phenolic, 7g acetone and 10g ethyl acetate, use a disperser to disperse, adjust the rotating speed to 700 rpm, and disperse for 15 minutes to obtain the first mixed solution; Kaolin, 15g of titanium dioxide, 0.5g of low molecular weight unsaturated polycarboxylic acid polymer solution BYK-P104, 2.5g of diethyl phthalate and 6g of ethyl acetate are mixed, and the disperser is used for dispersion, and the speed is adjusted to 700 rpm minutes, dispersed for 10 minutes to obtain the second mixed solution. Add the second mixed solution to the first mixed solution, use a disperser to disperse, adjust the rotating speed to 1200 rpm, disperse for 30 minutes, then put it into a sand mill for sand milling, adjust the feed pressure to 0.05MPa, sand The grinding temperature is 35° C., and the ink is sanded until the fineness reaches 6 μm.

[0054] The adhesion of the ink obtained in this embodiment was tested by...

Abstract

The application provides an ink, which comprises the following components by weight percentage: 25%-70% of chlorinated polypropylene carbonate; 5%-15% of rosin and / or rosin derivatives; 10%-30% 1% to 10% of acetone; 1% to 10% of filler; 5% to 25% of pigment; 1% to 10% of auxiliary agent. The invention adopts chlorinated polypropylene carbonate as the connecting material of the ink, and cooperates with other components to form the ink with good adhesion, and the solvent does not contain benzene substances, which will not cause pollution and is very environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of printing ink, in particular to an ink and a preparation method thereof. Background technique [0002] Ink, as the material basis of printing, appeared 2,000 years ago, and it is internationally recognized that China was the first country to use ink in ancient civilizations. At that time, ink was mainly used to write on bamboo and silk to convey information. [0003] In the later period, people improved the ink, using binders, pigments, fillers, additives and solvents, etc., uniformly mixing them and rolling them repeatedly to obtain a viscous colloidal fluid, which is modern ink, which can be used for printing. The pattern and text are displayed on the substrate by means of printing, which is used for various printings such as books, packaging and decoration, architectural decoration and electronic circuit boards. [0004] The development of the printing industry has greatly promoted the development of t...
