A kind of high-performance printing ink
Technical field
The present invention relates to a kind of high-performance printing ink.
Background technology
Water color ink mainly is the different of solvent with the difference of oil-based ink, and water color ink is solvent with water, and content of volatile organic compound is extremely low, and environmental pollution is little; Oil-based ink with the organic solvent is solvent, and is big for environment pollution.In the soft packaging industry; Because it is main mode that solvent type ink all adopts the volatility drying; The boiling point of solvent is low more, and is just volatile more and discharge the toxic gas contaminate environment, residual toxic substance also arranged being completed for printing its surface, back; And the solvent that high-performance printing ink uses is a water, can reduce the discharging of organic cpds greatly.
At present, high-performance printing ink generally adopts maleated rosin ester, WL 140 and modified acrylic acid emulsion etc. as connecting material, on glossiness, water resisting property and stability, have more problem, and the high-performance ink setting time is long, badly influences print speed.
Summary of the invention
The purpose of this invention is to provide a kind of high-performance printing ink, overcome the deficiency of oil-based ink and water color ink in the prior art.
To achieve these goals, technical scheme of the present invention is:
A kind of high-performance printing ink comprises the component of following parts by weight: cation aqueous polyurethane 20-22 part, alcohol-soluble polyurethane solution 13-15 part; Water-based paint 20-23 part; Ethanol 10-12 part, 1 part of the cured resin of binary chlorine, propyl acetate 5-7 part; The mass concentration that water 20-22 part, alcohol contain intermingle with the ammonia ester solution is 30-35%.
In order further to improve the performance of high-performance printing ink, preferred, said cation aqueous polyurethane is the ammonium ion aqueous polyurethane.
In order to guarantee the quality of high-performance printing ink, preferred, the number-average molecular weight of said cation aqueous polyurethane is 12-13 ten thousand.
In order to guarantee the dispersiveness of gained printing ink, preferred, the solvent that said alcohol contains intermingle with the ammonia ester solution is that Virahol and ethanol mass ratio are the mixture of (1:2)-(6:1).
In order to prolong the duration of service of high-performance printing ink, preferred, also comprise sanitas 1.1-1.3 weight part.
High-performance printing ink of the present invention has overcome the deficiency that oil-based ink in the prior art pollutes big and water color ink poor performance, has good dispersiveness, thermotolerance, attachment fastness, glossiness, water tolerance and a high print speed, and good bonding force.
Embodiment
In order to understand the present invention better, further illustrate content of the present invention below in conjunction with embodiment, but content of the present invention not only is confined to following embodiment.
Following water-based paint is the environment-friendly water-based pigment available from Toyo Ink limited-liability company; The cured resin of binary chlorine, brand: YG, model 14/50 is available from Dongguan City one sail resin ltd; Sanitas, model are TLR-703, available from the former chemical ltd of Dalian star, alcohol dissolve urethane available from the Zhong Shan of Guangdong Province stone east rise the smooth back of the body in town white in the manufacturing district, the trade mark is XH-PU304; Other is an analytical pure.
Embodiment 1
A kind of high-performance printing ink comprises the component of following parts by weight: 21 parts of ammonium ion aqueous polyurethanes, 14 parts of alcohol-soluble polyurethane solution; 22 parts of water-based paints, 1 part of the cured resin of binary chlorine, 5 parts of propyl acetates; The mass concentration that 11 parts of ethanol, 21 parts in water, alcohol contain intermingle with the ammonia ester solution is 30%.Ammonium ion aqueous polyurethane number-average molecular weight is 120,000, prepares according to ordinary method.
The solvent that said alcohol contains intermingle with the ammonia ester solution is that Virahol and ethanol mass ratio are the mixture of 1:2.
With the above-mentioned raw materials mixing, be ground to particle diameter and be not more than 4 microns, get high-performance printing ink.

The solvent that said alcohol contains intermingle with the ammonia ester solution is that Virahol and ethanol mass ratio are the mixture of 6:1.
With the above-mentioned raw materials mixing, be ground to particle diameter and be not more than 4 microns, get high-performance printing ink.
Embodiment 3
A kind of high-performance printing ink comprises the component of following parts by weight: 22 parts of ammonium ion aqueous polyurethanes, 15 parts of alcohol-soluble polyurethane solution; 20 parts of water-based paints, 1 part of the cured resin of binary chlorine, 10 parts of ethanol; 6 parts of propyl acetates, 22 parts in water, 1.3 parts of sanitass; The mass concentration that alcohol contains intermingle with the ammonia ester solution is 30%, and ammonium ion aqueous polyurethane number-average molecular weight is 130,000, prepares according to ordinary method.
The solvent that said alcohol contains intermingle with the ammonia ester solution is that Virahol and ethanol mass ratio are the mixture of 3:1.
With the above-mentioned raw materials mixing, be ground to particle diameter and be not more than 4 microns, get high-performance printing ink.
High-performance printing ink with the foregoing description gained carries out performance test, and testing method is with reference to " the stdn Performance Detection standard of printing ink ", and the result sees table 1.
