Embodiment Construction

[0007] Below in conjunction with embodiment the present invention is further described.

[0008] A water-based ink, the components and their weight percentages are: 50%-60% of spare binder, 30%-35% of water-based pigment paste, 2%-3% of water-based wax paste, some deionized water, water-based defoaming 0.3% of the agent, 0.5%-1% of the water-based dispersant, and the acid-base neutralizer can be adjusted to a ratio range of pH 7-7.5.

[0009] The connecting material is synthesized from film-forming emulsion and dry resin emulsion dissolved in water-based modified polyurethane resin.

[0010] The present invention replaces the solvent-type PVC heat-shrinkable ink currently on the market, strengthens the development of beverage outer packaging bags in the direction of environmental protection, non-toxicity, and energy saving, enhances social benefits and economic benefits of enterprises, and guides the market to move towards VOC-free and zero-emission.

Abstract

The invention relates to water-based ink. The water-based ink is prepared from, by weight, 50-60% of spare connecting materials, 30-35% of water-based pigment color paste, 2-3% of water-based max paste, a quantity of deionized water, 0.3% of water-based defoaming agent, 0.5-1% of water-based dispersing agent and an acid-base neutralization agent, wherein a pH value of the ink is adjusted to be 7-7.5. The water-based ink replaces water-based PVC thermal shrinking ink in the current market, development of beverage external packaging bags towards environmental protection, innocuity and energy conservation is enhanced, social benefits and economic benefits of enterprises are increased, and the water-base ink guides the market into VOC zero release.

Description

technical field [0001] The invention belongs to the technical field of surface printing films, and relates to a water-based ink applied to the surface (inside) printing of OPS heat shrinkable films, PVC heat shrinkable films and PET heat shrinkable films. Background technique [0002] The water-based PVC heat-shrinkable inks currently on the market cannot be completely environmentally friendly, non-toxic, and have VOC emissions, and the inks produced can only be printed at a printing speed of 80m / min, and cannot be compared with solvent-based inks in terms of efficiency. . Contents of the invention [0003] In order to overcome the above-mentioned technical shortcomings, the present invention provides a water-based ink, which replaces the water-based PVC heat-shrinkable ink currently on the market, strengthens the development of beverage outer packaging bags in the direction of environmental protection, non-toxicity, and energy saving, and enhances social benefits and econ...
