Decorative paper water-based gravure printing ink composition

Abstract

The invention provides a decorative paper gravure printing ink composition which comprises the components in parts by weight: component A: 10-50 parts of at least one organic pigment and/or inorganic pigment, component B: 10-40 parts of at least one acrylic resin or the solution thereof, component C: 0.5-1 part of at least one wetting agent, component D: 0-10 parts of water-soluble supporting substance, component E: 0-5 parts of additive and component F: 100 parts of water. A method for preparing the composition comprises: the components are mixed for pulping according to the parts by weight and ground by a bead mill to have the grain diameter of 0.5-2mum under the cooling condition; then, the concentration of the final pigment is adjusted by softened water, and the ink is obtained by separating grinding medium and water-based color paste.

Description

technical field [0001] The invention relates to the application field of gravure printing and coloring technology for decorative paper, in particular to a water-based gravure printing ink composition for decorative paper. Background technique [0002] The global shortage of forest resources has promoted the mass production of wood-based panels, and the surface decoration problem has become an urgent task to solve the application of wood-based panels instead of solid wood. Therefore, the production technology of decorative paper has developed rapidly, and signs and trends of development have also appeared in our country. This kind of paper has beautiful appearance, realistic texture, soft luster, warm touch, wear-resistant, stain-resistant, flexible and elastic, suitable for various shapes, and opens up more space for furniture design and wood-based panel utilization. Because it has a final decorative surface, it simplifies the furniture production process, improves producti...

AI Technical Summary

Problems solved by technology

The fastness is improved, the printing line, the pressure plate sticking to the plate, the heat resistance and light resistance (weather resistance) are insufficient; in recent years, with the progress of synthetic water-based resin, there has been great progress in the printing of decorative paper, which still cannot meet the requirements of decorative paper printing. In terms of printing applicability, print clarity, adhesion, melamine-formaldehyde resin-impregnated resin penetration, press plate heat resistance, UV resistance and light resistance, the requirements are comparable to the highest level of German Hartmann ink and Spanish Tianba ink. The level of gravure printing ink of similar products is far behind

[0005] 1. Common problems in printing suitability: (1) In the printing process, it is dark first and then light, and after 500-1000m, the color becomes lighter; (2) During the printing process, the knife line, printing jumping knife, and insufficient dry fastness of the printed product , poor color reproduction reproducibility;

[0006] 2. Common problems of dipping melamine glue: dipping glue fades, miscible with glue, color drift; dipping speed car 10-40m.;

[0009] 5. Plate processing crisp edge

[0010] For a long time, the printing of high-grade decorative paper and export products have mainly relied on imported ink, which has reduced the competitiveness of product exports in the international market.
