Aqueous dual-PE printing ink

Abstract

The invention discloses aqueous dual-PE printing ink. The printing ink is prepared via the following processing steps: (1) preparation of varnish: mixing aqueous PU resin with acrylic resin in a proportion of 6 to 4 to obtain a mixed solution, adding 1-2% of DC-51, 0.5-1% of DC65 and 1-5% of deionized water to perform dispersion by taking the mass of the mixed solution as 100% in calculation so as to enable the viscosity of the mixed solution to be kept for 15-20 seconds; (2) preparation of color paste: enabling the following ingredients as raw materials, of which the mass percent is as follows, to be prepared into the color paste: 30-35% of resin, 4.5-5% of a wetting agent, 0.5-1% of a surface active agent, 25-27% of deionized water, stirring evenly, then adding 38-40% of an organic pigment, grinding the ingredients below 7.5 microns to prepare the color paste; (3) ink blending: mixing and dispersing 74% of varnish, 25% of color paste, 0.3% of DC-51, 0.5% of DC-65, and 0.2% of AWP95 to prepare the printing ink. By the DC-51, the scraping resistance of an ink layer is improved; and the aqueous PU resin and the acrylic resin are mixed, and the cost is low.

Description

technical field [0001] The invention relates to water-based ink, in particular to water-based double PE ink. Background technique [0002] At present, in the existing water-based ink, the content of toner is usually only 35%. Increasing the amount of toner will lead to poor state of the color paste, which will affect the quality of the ink. Therefore, it is impossible to improve the ink quality by changing the amount of toner. Contents of the invention [0003] Aiming at the above problems, the present invention provides a water-based double PE ink, which uses ammonia water to dissolve the resin, increases the drying speed, increases the ratio of toner, improves the quality of the ink, and overcomes the problem that the amount of toner cannot be increased in the traditional method. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted in the present invention is: water-based double PE ink, comprising the following process steps, ...
