Problems solved by technology

[0004] At present, in the development of water-based gravure plastic film surface printing matte ink, the main problems include: first, in terms of the balance between drying rate and VOC content, the current situation is mainly that when the VOC content is lower than 30%, the printing speed is higher than 100m / s, When the coaxing channel is extended to the limit of 3 meters, the printed matter cannot be completely dried; the second is that the leveling property of the solvent-based surface printing matte ink is worse than that of the previous solvent-based surface printing matte ink. When KPP proofing, the second printing plate (80% neutral depth plate ) are all transferred unevenly, and the water-based ink of the third shallow screen plate is not transferred in place, resulting in the water-based gravure plastic film surface printing matte ink temporarily failing to meet environmental protection requirements and printing effects

Embodiment 1-3

[0028] Adopt the components and proportions shown in Table 1 respectively

[0029] The preparation methods are as follows: except the adhesion agent, antifoaming agent, drying regulator and 9% deionized water, the rest of the resin emulsion and solvent are first stirred evenly, and then the pigment and matte material are added and the stirring is continued. Uniform; the mixed components are then ground by a grinder, and the grinding is stopped after the fineness reaches # The cup is 20-28 seconds / 25°C, the pH value is between 8.0-9.0, and finally filtered and packaged.

[0030] Printing requirements: printing speed: 150-240 m / min;

[0031] Gravure depth: 30-45 microns;

[0032] Drying temperature: 45-55°C;

[0033] Printing viscosity: 11-15 seconds / 25°C / thin-walled 3# Zahn cup.

[0034] Components and ratios thereof of the printing ink of table 1 embodiment 1-3

[0035]

[0036] Among them, the "self-modifying resin emulsion" in Table 1 is obtained by emulsifying and mi...

Abstract

The invention discloses water-based gravure surface printing matte ink for a plastic film and a preparation method thereof. The water-based gravure surface printing matte ink comprises the following raw materials by weight (totaling 100%): 10 to 15% of a pigment, 6 to 8% of a matt material, 38 to 42% of a composite connection material, 32.5-27.8% of a solvent and 6-8% of accessories. The water-based gravure surface printing matte ink has the advantages of safety, environmental-friendliness, lower VOC content, good fluidity, high color concentration, good printability, low printed product glossiness, good leveling property, layered hue, good fastness, and no harmful substances after drying. Prints have blocking resistance, migration resistance, rub resistance, and water resistance. The water-based gravure surface printing matte ink is suitable for market requirements.

Description

technical field [0001] The invention relates to an ink, in particular to a water-based gravure plastic film surface printing matte ink and a preparation method thereof. Background technique [0002] Environmental protection and the ink industry combine the actual situation of water-based gravure inks, according to the requirements of the "People's Republic of China Environmental Protection Industry Standard HJ / T371-2007", the corresponding environmental protection and related testing standards for gravure water-based inks GB / T4103-2010 " "Water-based gravure plastic film surface printing ink" aims to specify the technical requirements, test methods, etc. of water-based gravure plastic film surface printing ink. The special function water-based gravure plastic film surface printing matte ink has low gloss, and the printed matter has a hazy and mysterious feeling. Large market demand, but also within the standard requirements. [0003] HJ / T371-2007 standard for water-based gr...
