Background technology
Water color ink is mainly the different of solvent from the difference of oil-based ink, and water color ink take water as solvent, and content of volatile organic compound is extremely low, and environmental pollution is little; Oil-based ink take organic solvent as solvent, big for environment pollution.At Flexible-Packaging Industry, because solvent type ink all adopts volatility drying to be main mode, the boiling point of solvent is lower, more volatile and discharge toxic gas contaminate environment, after being completed for printing, also there is residual toxic substance on its surface, and the solvent that High-performance ink uses is water, the discharge of organic compound greatly can be reduced.
At present, High-performance ink generally adopts maleated rosin ester, polyacrylic resin and modified acrylic acid emulsion etc. as binder, glossiness, water resisting property and stability exist more problem, and High-performance ink is long for time of drying, badly influences print speed.
Summary of the invention
The object of this invention is to provide a kind of High-performance ink, overcome the deficiency of the medium oil ink of prior art and water color ink.
To achieve these goals, technical scheme of the present invention is:
A kind of High-performance ink, comprise 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, the cured resin of binary chlorine 1 part, propyl acetate 5-7 part, water 20-22 part, the mass concentration of the molten polyurethane solution of alcohol is 30-35%.
In order to improve the performance of High-performance ink further, preferably, described cation aqueous polyurethane is ammonium ion aqueous polyurethane.
In order to ensure the quality of High-performance ink, preferably, the number-average molecular weight of described cation aqueous polyurethane is 12-13 ten thousand.
In order to ensure the dispersiveness of gained ink, preferably, the mixture of the solvent of the molten polyurethane solution of described alcohol to be Virahol and ethanol mass ratio be (1:2)-(6:1).
In order to extend the duration of service of High-performance ink, preferably, sanitas 1.1-1.3 weight part is also comprised.
High-performance ink of the present invention overcomes the deficiency of the large and water color ink poor performance of the medium oil ink contamination of prior art, has good dispersiveness, thermotolerance, attachment fastness, glossiness, water tolerance and high print speed, and good bonding force.
